MENTAL HEALTH AND MENTAL ILLNESS
Mental Health



The World Health Organization defines health as a state of complete physical, mental, and social wellness, not merely the
absence of disease or infirmity. This definition emphasizes health as a positive state of well-being. People in a state of
emotional, physical, and social well-being fulfill life responsibilities, function effectively in daily life, and are satisfied with
their interpersonal relationships and themselves.
In most cases, mental health is a state of emotional, psychological, and social wellness evidenced by satisfying interpersonal
relationships, effective behavior and coping, positive self-concept, and emotional stability
Mental health has many components, and a wide variety of factors influence it. These factors interact; thus, a person’s mental
health is a dynamic, or ever-changing, state. Factors influencing a person’s mental health can be categorized as individual,
interpersonal, and social/cultural.
Individual, or personal, factors include a person’s biologic makeup, autonomy and independence, self-esteem, capacity
for growth, vitality, ability to find meaning in life, emotional resilience or hardiness, sense of belonging, reality
orientation, and coping or stress management abilities.
Interpersonal, or relationship, factors include effective communication, ability to help others, intimacy, and a balance
of separateness and connectedness.
Social/cultural, or environmental, factors include a sense of community, access to adequate resources, intolerance of
violence, support of diversity among people, mastery of the environment, and a positive, yet realistic, view of one’s
world
Mental Illness



Mental illness includes disorders that affect mood, behavior, and thinking, such as depression, schizophrenia, anxiety
disorders, and addictive disorders. Mental disorders often cause significant distress or impaired functioning or both.
Individuals experience dissatisfaction with self, relationships, and ineffective coping. Daily life can seem overwhelming or
unbearable. Individuals may believe that their situation is hopeless.
Factors contributing to mental illness can also be viewed within individual, interpersonal, and social/cultural categories.
Individual factors include biologic makeup, intolerable or unrealistic worries or fears, inability to distinguish reality
from fantasy, intolerance of life’s uncertainties, a sense of disharmony in life, and a loss of meaning in one’s life.
Interpersonal factors include ineffective communication, excessive dependency on or withdrawal from relationships,
no sense of belonging, inadequate social support, and loss of emotional control.
Social/cultural factors include lack of resources, violence, homelessness, poverty, an unwarranted negative view of the
world, and discrimination such as stigma, racism, classism, ageism, and sexism.
----------------------------------------------------------------------------------------------------------------------------------------------------------HISTORICAL PERSPECTIVES OF THE TREATMENT OF MENTAL ILLNESS
Period of Enlightenment and Creation of Mental Institutions


Sigmund Freud and Treatment of Mental Disorders





Those with mental disorders were viewed as either divine or demonic, depending on their behavior. Individuals seen as divine
were worshipped and adored; those seen as demonic were ostracized, punished, and sometimes burned at the stake.
Later, Aristotle (382–322 BC) attempted to relate mental disorders to physical disorders and developed his theory that the
amounts of blood, water, and yellow and black bile in the body controlled the emotions. These four substances, or humors,
corresponded with happiness, calmness, anger, and sadness. Imbalances of the four humors were believed to cause mental
disorders; therefore, treatment was aimed at restoring balance through bloodletting, starving, and purging.
Possessed by demons
In early Christian times (1–1000 AD), primitive beliefs and superstitions were strong. All diseases were again blamed
on demons, and the mentally ill were viewed as possessed. Priests performed exorcisms to rid sufferers of evil spirits.
When that failed, they used more severe and brutal measures, such as incarceration in dungeons, flogging, and starving.
The period of scientific study and treatment of mental disorders began with Sigmund Freud and others, such as Emil
Kraepelin and Eugen Bleuler. With these men, the study of psychiatry and the diagnosis and treatment of mental illness
started in earnest.
Freud challenged society to view human beings objectively. He studied the mind, its disorders, and their treatment as no one
had done before. Many other theorists built on Freud’s pioneering work. Kraepelin began classifying mental disorders
according to their symptoms, and Bleuler coined the term schizophrenia.
Development of Psychopharmacology


A great leap in the treatment of mental illness began in about 1950 with the development of psychotropic drugs, or drugs
used to treat mental illness. Chlorpromazine (Thorazine), an antipsychotic drug, and lithium, an antimanic agent, were the
first drugs to be developed.
Over the following 10 years, monoamine oxidase inhibitor antidepressants; haloperidol (Haldol), an antipsychotic; tricyclic
antidepressants; and antianxiety agents, called benzodiazepines, were introduced. For the first time, drugs actually reduced
agitation, psychotic thinking, and depression.
Move toward Community Mental Health


Deinstitutionalization, a deliberate shift from institutional care in state hospitals to community facilities, began. Community
mental health centers served smaller geographic catchment, or service, areas that provided less restrictive treatment located
closer to individuals’ homes, families, and friends.
These centers provided emergency care, inpatient care, outpatient services, partial hospitalization, screening services, and
education. Thus, deinstitutionalization accomplished the release of individuals from long-term stays in state institutions, the
decrease in admissions to hospitals, and the development of community-based
----------------------------------------------------------------------------------------------------------------------------MENTAL ILLNESS IN THE 21ST CENTURY

Ancient Times
People of ancient times believed that any sickness indicated displeasure of the gods and, in fact, was a punishment for sins and
wrongdoing.
In the 1790s, formulated the concept of asylum as a safe refuge or haven offering protection at institutions where people had
been whipped, beaten, and starved because they were mentally ill (Gollaher, 1995).
The period of enlightenment was short-lived. Within 100 years after the establishment of the first asylum, state hospitals
were in trouble. Attendants were accused of abusing the residents, the rural locations of hospitals were viewed as isolating
patients from their families and homes, and the phrase insane asylum took on a negative connotation.


Some believe that deinstitutionalization has had negative as well as positive effects. Although deinstitutionalization reduced
the number of public hospital beds by 80%, the number of admissions to those beds correspondingly increased by 90%. Such
findings have led to the term revolving door effect.
Such findings have led to the term revolving door effect. Although people with severe and persistent mental illness have
shorter hospital stays, they are admitted to hospitals more frequently.

Primary function of the nervous system

Coordinates all activities of the body (sending, receiving, and interpreting information)

Enables the body to respond and adapt to changes both inside and out.
Part of Nervous System

Central Nervous System (brain and spinal cord)

Peripheral Nervous System




Brain – located sa cranium ng skull.
Main sections are; cerebrum, cerebellum, diencephalon, midbrain, pons, and medulla oblongata
Protected by meninges, dura mater, arachnoid mater, and pia mater
The space between the arachnoid mater and pia mater is composed of cerebrospinal fluid
The two hemisphere is connected by a nerve tract called corpus callosum
Cerebrum – largest part. Consists of four lobes; frontal, parietal, temporal, occipital;
Frontal Lobe – reasoning and thought
Parietal Lobe – integrating sensory information
Temporal Lobe – processing auditory information from the ears
Occipital Lobe – processing visual information from the eyes
Cerebellum – located below the cerebrum and above the 1st cervical of the neck
Responsible for muscle coordination, balance posture, and muscle tone
Diencephalon – contains two structures; thalamus and hypothalamus
Thalamus behaves like a relay station and direct sensory impulses to the cerebrum
Hypothalamus controls and regulates temperature, appetite, water balance, sleep and blood vessel constriction and
dilation. Plays control in the emotion such as anger, fear, pleasure, pain and affection

Midbrain – located below cerebrum and top of brain stem; responsible for certain eyes and auditory reflexes

Pons – located below the midbrain; responsible for certain reflexes such as chewing, tasting, and saliva production

Medulla Oblongata – located as the bottom of the brainstem; connects to the spinal cord; aka “The Center for Respiration”
Regulates heart and blood vessel function, digestion, respiration, swallowing, coughing, sneezing, blood pressure
Spinal cord – is the link between the brain and the nerves in the rest of the body. Protected by the vertebral column.
Hollow tube containing cerebral spinal fluid
31 spinal nerves arise from the spinal cord ( transmit information form organs to the brain, and vice versa)
4 regions; cervical, thoracic, lumbar, spinal nerves
Afferent spinal nerves – responsible for carrying information from the body to the brain
Efferent spinal nerves – responsible for carrying information from the brain to the body

Neurotransmitters




Approximately 100 billion brain cells form groups of neurons, or nerve cells that are arranged in networks. These neurons
communicate information with one another by sending electrochemical messages from neuron to neuron, a process called
neurotransmission
These electrochemical messages pass from the dendrites (projections from the cell body), through the soma or cell body,
down the axon (long extended structures), and across the synapses (gaps between cells) to the dendrites of the next neuron.
In the nervous system, the electrochemical messages cross the synapses between neural cells by way of special chemical
messengers called neurotransmitters.
Neurotransmitters are the chemical substances manufactured in the neuron that aid in the transmission of information
throughout the body. They either excite or stimulate an action in the cells (excitatory) or inhibit or stop an action (inhibitory).
These neurotransmitters fit into specific receptor cells embedded in the membrane of the dendrite, just like a certain key
shape fits into a lock. After neurotransmitters are released into the synapse and relay the message to the receptor cells, they
are either transported back from the synapse to the axon to be stored for later use (reuptake) or metabolized and inactivated
by enzymes, primarily monoamine oxidase

Modulates other neurotransmitters
Dopamine - a neurotransmitter located primarily in the brain stem. It is generally excitatory and is synthesized from tyrosine, a
dietary amino acid. Dopamine is implicated in schizophrenia and other psychoses as well as in movement disorders such as
Parkinson disease. Antipsychotic medications work by blocking dopamine receptors and reducing dopamine activity.
Norepinephrine - the most prevalent neurotransmitter in the nervous system, is located primarily in the brain stem and plays a role
in changes in attention, learning and memory, sleep and wakefulness, and mood regulation. Excess norepinephrine has been
implicated in several anxiety disorders; deficits may contribute to memory loss, social withdrawal, and depression. Some
antidepressants block the reuptake of norepinephrine, while others inhibit MAO from metabolizing it.
Epinephrine - has limited distribution in the brain but controls the fight or flight response in the peripheral nervous system.
Serotonin - is derived from tryptophan, a dietary amino acid. The function of serotonin is mostly inhibitory, and it is involved in
the control of food intake, sleep and wakefulness, temperature regulation, pain control, sexual behavior, and regulation of emotions.
-
Serotonin plays an important role in anxiety, mood disorders, and schizophrenia. It has been found to contribute to the
delusions, hallucinations, and withdrawn behavior seen in schizophrenia. Some antidepressants block serotonin reuptake,
thus leaving it available longer in the synapse, which results in improved mood.
Histamine – The role of histamine in mental illness is under investigation. It is involved in peripheral allergic responses, control of
gastric secretions, cardiac stimulation, and alertness. Some psychotropic drugs block histamine, resulting in weight gain, sedation,
and hypotension.
Acetylcholine - neurotransmitter found in the brain, spinal cord, and peripheral nervous system, particularly at the neuromuscular
junction of skeletal muscle. It can be excitatory or inhibitory.
-
It is synthesized from dietary choline found in red meat and vegetables and has been found to affect the sleep–wake cycle
and to signal muscles to become active. Studies have shown that people with Alzheimer disease have decreased
acetylcholinesecreting neurons, and people with myasthenia gravis (a muscular disorder in which impulses fail to pass the
myoneural junction, which causes muscle weakness) have reduced acetylcholine receptors.
Glutamate - an excitatory amino acid that can have major neurotoxic effects at high levels. It has been implicated in the brain
damage caused by stroke, hypoglycemia, sustained hypoxia or ischemia, and some degenerative diseases such as Huntington or
Alzheimer.
Gamma-aminobutyric acid (γ-aminobutyric acid, or GABA), an amino acid, is the major inhibitory neurotransmitter in the brain
and has been found to modulate other neurotransmitter systems rather than to provide a direct stimulus. Drugs that increase GABA
function, such as benzodiazepines, are used to treat anxiety and to induce sleep.
More advanced imaging techniques, such as positron emission tomography (PET) and single-photon emission computed
tomography (SPECT), are used to examine the function of the brain.

Limitations of Brain Imaging Techniques
-----------------------------------------------------------------------------------------------------------------------------------------------------------
At one time, the brain could be studied only through surgery or autopsy. During the past 25 years, however, several brain
imaging techniques have been developed that now allow visualization of the brain’s structure and function.
These techniques are useful for diagnosing some disorders of the brain and have helped correlate certain areas of the brain
with specific functions. Brain imaging techniques are also useful in research to find the causes of mental disorders.

NEUROBIOLOGIC CAUSES OF MENTAL ILLNESS


Computed tomography (CT), also called computed axial tomography, is a procedure in which a precise x-ray beam takes crosssectional images (slices) layer by layer. The person undergoing CT must lie motionless on a 65 stretcher-like table for about 20 to
40 minutes as the stretcher passes through a tunnel-like “ring” while the serial x-rays are taken.
CT can visualize the brain’s soft tissues, so it is used to diagnose primary tumors, metastases, and effusions and to
determine the size of the ventricles of the brain. Some people with schizophrenia have been shown to have enlarged
ventricles; this finding is associated with a poorer prognosis and marked negative symptoms
Magnetic resonance imaging (MRI), a type of body scan, an energy field is created with a huge magnet and radio waves. The
energy field is converted to a visual image or scan. MRI produces more tissue detail and contrast than CT and can show blood flow
patterns and tissue changes such as edema.
-
-
The use of radioactive substances in PET and SPECT limits the number of times a person can undergo these tests. There is
the risk that the client will have an allergic reaction to the substances. Some clients may find receiving intravenous doses of
radioactive material frightening or unacceptable.
Imaging equipment is expensive to purchase and maintain, so availability can be limited. A PET camera costs about $2.5
million; a PET scanning facility may take up to $6 million to establish.
Some persons cannot tolerate these procedures because of fear or claustrophobia.
Researchers are finding that many of the changes in disorders such as schizophrenia are at the molecular and chemical levels
and cannot be detected with current imaging techniques

Radioactive substances are injected into the blood; the flow of those substances in the brain is monitored as the client
performs cognitive activities as instructed by the operator. PET uses two photons simultaneously; SPECT uses a single
photon.
PET provides better resolution with sharper and clearer pictures and takes about 2 to 3 hours; SPECT takes 1 to 2 hours.
PET and SPECT are used primarily for research, not for the diagnosis and treatment of clients with mental disorders
These scans have shown that clients with Alzheimer disease have decreased glucose metabolism in the brain and decreased
cerebral blood flow. Some persons with schizophrenia also demonstrate decreased cerebral blood flow.
It can also be used to measure the size and thickness of brain structures; persons with schizophrenia can have as much as
7% reduction in cortical thickness. The person undergoing an MRI must lie in a small, closed chamber and remain
motionless during the procedure, which takes about 45 minutes.
Those who feel claustrophobic or have increased anxiety may require sedation before the procedure. Clients with
pacemakers or metal implants, such as heart valves or orthopedic devices, cannot undergo MRI.
To date, one of the most promising discoveries is the identification in 2007 of variations in the gene SORL1 that may be a
factor in late-onset Alzheimer disease.
Current theories and studies indicate that several mental disorders may be linked to a specific gene or combination of genes
but that the source is not solely genetic; non-genetic factors also play important roles.
Three types of studies are commonly conducted to investigate the genetic basis of mental illness:
1. Twin studies are used to compare the rates of certain mental illnesses or traits in monozygotic (identical) twins, who
have an identical genetic makeup, and dizygotic (fraternal) twins, who have a different genetic makeup. Fraternal twins
have the same genetic similarities and differences as nontwin siblings.
2. Adoption studies are used to determine a trait among biologic versus adoptive family members.
3. Family studies are used to compare whether a trait is more common among first-degree relatives (parents, siblings,
and children) than among more distant relatives or the general population.
Stress and the Immune System (Psychoimmunology)


Psychoimmunology, a relatively new field of study, examines the effect of psychosocial stressors on the body’s immune
system. A compromised immune system could contribute to the development of a variety of illnesses, particularly in
populations already genetically at risk. So far, efforts to link a specific stressor with a specific disease have been unsuccessful.
However, the immune system and the brain can influence neurotransmitters. When the inflammatory response is critically
involved in illnesses such as multiple sclerosis or lupus erythematosus, mood dysregulation and even depression are common.
Infection as a Possible Cause

Theories that are being developed and tested include the existence of a virus that has an affinity for tissues of the CNS, the
possibility that a virus may actually alter human genes, and maternal exposure to a virus during critical fetal development of
the nervous system.

Prenatal infections may impact the developing brain of the fetus, giving rise to a proposed theory that inflammation may
causally contribute to the pathology of schizophrenia.
The conventional, or first-generation, antipsychotic drugs are potent antagonists (blockers) of D2, D3, and D4. This not only
makes them effective in treating target symptoms but also produces many extrapyramidal side effects (discussion to follow) because
of the blocking of the D2 receptors.
-----------------------------------------------------------------------------------------------------------------------------------------------------------PSYCHOPHARMACOLOGY
Medication management is a crucial issue that greatly influences the outcomes of treatment for many clients with mental disorders.





Efficacy- maximal therapeutic effect that a drug can achieve
Potency- Describes the amount of the drug needed to achieve that maximum effect. Low potency drugs require higher
dosages to achieve efficacy, while high-potency drugs achieve efficacy at lower dosages.
Half-life- is the time it takes for half of the drug to be removed from the bloodstream. Drugs with a shorter half-life may
need to be given 3-4 times a day, but drugs with a longer half-life may be given once a day.
The U.S. Food and Drug Administration (FDA) is responsible for supervising the testing and marketing of medications
for public safety. These activities include clinical drug trials for new drugs and monitoring the effectiveness and side effects
of medications.
At times, a drug will prove effective for a disease that differs from the one involved in original testing and FDA approval.
This is called off-label use. An example is some anticonvulsant drugs (approved to prevent seizures) that are prescribed for
their effects in stabilizing the moods of clients with bipolar disorder (off-label use).
When a drug is found to have serious or life-threatening side effects, even if such side effects are rare, the FDA may issue a
black box warning. This means that package inserts must have a highlighted box, separate from the text, which contains a
warning about the serious or life-threatening side effects.
Newer, atypical or second-generation antipsychotic drugs, such as clozapine (Clozaril), are relatively weak blockers of D2,
which may account for the lower incidence of extrapyramidal side effects. In addition, second-generation antipsychotics inhibit the
reuptake of serotonin, as do some of the antidepressants, increasing their effectiveness in treating the depressive aspects of
schizophrenia.
The third generation of antipsychotics, called dopamine system stabilizers, is being developed. These drugs are thought to
stabilize dopamine output; that is, they preserve or enhance dopaminergic transmission when it is too low and reduce it when it is
too high.
---------------------------------------------------------------------------------------------------------------------------------------------------------Side effects of Antipsychotic Drugs

Extrapyramidal Side Effects.
Extrapyramidal symptoms (EPSs), serious neurologic symptoms, are the major side effects of antipsychotic drugs. They
include acute dystonia, pseudoparkinsonism, and akathisia. Although often collectively referred to as EPSs, each of
these reactions has distinct features.
Blockade of D2 receptors in the midbrain region of the brain stem is responsible for the development of EPSs. Firstgeneration antipsychotic drugs cause a greater incidence of EPSs than do second-generation antipsychotic drugs, with
ziprasidone (Geodon) rarely causing EPSs

A medication is selected based on its effect on the client’s target symptoms such as delusional thinking, panic attacks, or
hallucinations. The medication’s effectiveness is evaluated largely by its ability to diminish or eliminate the target symptoms.
Many psychotropic drugs must be given in adequate dosages for some time before their full effects are realized. For example,
tricyclic antidepressants can require 4 to 6 weeks before the client experiences optimal therapeutic benefit.
The dosage of medication is often adjusted to the lowest effective dosage for the client. Sometimes a client may need higher
dosages to stabilize his or her target symptoms, while lower dosages can be used to sustain those effects over time.
As a rule, older adults require lower dosages of medications than do younger clients to experience therapeutic effects. It may
also take longer for a drug to achieve its full therapeutic effect in older adults.
Psychotropic medications are often decreased gradually (tapering) rather than abruptly. This is because of potential problems
with rebound (temporary return of symptoms), recurrence (of the original symptoms), or withdrawal (new symptoms
resulting from discontinuation of the drug).
Follow-up care is essential to ensure compliance with the medication regimen, to make needed adjustments in dosage, and
to manage side effects.
Compliance with the medication regimen is often enhanced when the regimen is as simple as possible in terms of both the
number of medications prescribed and the number of daily doses.

Antipsychotic Drugs



Antipsychotic drugs, formerly known as neuroleptics, are used to treat the symptoms of psychosis, such as the delusions
and hallucinations seen in schizophrenia, schizoaffective disorder, and the manic phase of bipolar disorder.
Antipsychotic drugs work by blocking receptors of the neurotransmitter dopamine. They have been in clinical use since the
1950s. They are the primary medical treatment for schizophrenia and are also used in psychotic episodes of acute mania,
psychotic depression, and drug-induced psychosis.
Clients with dementia who have psychotic symptoms sometimes respond to low dosages of conventional antipsychotics.
Second-generation antipsychotics can increase mortality rates in elderly clients with dementia-related psychosis. Short-term
therapy with antipsychotics may be useful for transient psychotic symptoms such as those seen in some clients with borderline
personality disorder.

Anticholinergic Side Effects.
Anticholinergic side effects often occur with the use of antipsychotics and include orthostatic hypotension, dry mouth,
constipation, urinary hesitance or retention, blurred near vision, dry eyes, photophobia, nasal congestion, and decreased
memory.
These side effects usually decrease within 3 to 4 weeks but do not entirely remit. The client taking anticholinergic
agents for EPSs may have increased problems with anticholinergic side effects. Using calorie-free beverages or hard
candy may alleviate dry mouth, and stool softeners, adequate fluid intake, and the inclusion of grains and fruit in the
diet may prevent constipation.
Ego Defense Mechanisms. Freud believed that the self, or ego, uses ego defense mechanisms, which are methods of attempting to
protect the self and cope with basic drives or emotionally painful thoughts, feelings, or events.

Moving back to a previous developmental stage to feel safe or have needs met
-----------------------------------------------------------------------------------------------------------------------------------------------------------PSYCHOANALYTIC THEORIES
-----------------------------------------------------------------------------------------------------------------------------------------------------Five Stages of Psychosexual Development.
Sigmund Freud: The Father of Psychoanalysis
Sigmund Freud developed psychoanalytic theory in the late 19th and early 20th centuries in Vienna. Psychoanalytic theory supports
the notion that all human behavior is caused and can be explained (deterministic theory). Freud believed that repressed (driven from
conscious awareness) sexual impulses and desires motivate much human behavior.
Freud based his theory of childhood development on the belief that sexual energy, termed libido, was the driving force of human
behavior.
Oral
Birth to
months
18
Personality Components: Id, Ego, and Superego.
Anal
18–36 months
The id is the part of one’s nature that reflects basic or innate desires such as pleasure-seeking behavior, aggression, and sexual
impulses. The id seeks instant gratification, causes impulsive unthinking behavior, and has no regard for rules or social convention.
Phallic/oedipal
3–5 years
The superego is the part of a person’s nature that reflects moral and ethical concepts, values, and parental and social expectations;
therefore, it is in direct opposition to the id.
Latency
5–11
years
Genital
11–13 years
The third component, the ego, is the balancing or mediating force between the id and the superego. The ego represents mature and
adaptive behavior that allows a person to function successfully in the world. Freud believed that anxiety resulted from the ego’s
attempts to balance the impulsive instincts of the id with the stringent rules of the superego.
or
13
Major site of tension and gratification is the mouth, lips, and tongue; includes biting and
sucking activities. Id is present at birth. Ego develops gradually from rudimentary structure
present at birth.
Anus and surrounding area are major source of interest. Voluntary sphincter control (toilet
training) is acquired
Genital is the focus of interest, stimulation, and excitement. Penis is organ of interest for
both sexes. Masturbation is common. Penis envy is seen in girls; oedipal complex (wish
to marry opposite-sex parent and be rid of same-sex parent) is seen in boys and girls.
Resolution of oedipal complex. Sexual drive channeled into socially appropriate activities
such as school work and sports. Formation of the superego. Final stage of psychosexual
development
Begins with puberty and the biologic capacity for orgasm; involves the capacity for true
intimacy.
Transference and Countertransference.


INTERPERSONAL THEORIES
Transference occurs when the client displaces onto the therapist attitudes and feelings that the client originally experienced
in other relationships. Transference patterns are automatic and unconscious in the therapeutic relationship. (patient-nurse)
Countertransference occurs when the therapist displaces onto the client attitudes or feelings from his or her past.
-----------------------------------------------------------------------------------------------------------------------------------------------------------DEVELOPMENTAL THEORIES
Harry Stack Sullivan: Interpersonal Relationships and Milieu Therapy
Five Life Stages. Sullivan established five life stages of development— infancy, childhood, juvenile, preadolescence, and
adolescence, each focusing on various interpersonal relationships. He also described three developmental cognitive modes of
experience and believed that mental disorders are related to the persistence of one of the early modes
Stage
Infancy
Age
Birth to onset of language
Focus
Primary need exists for bodily contact and tenderness. Prototaxic mode
dominates (no relation between experiences). Primary zones are oral and
anal. If needs are met, infant has sense of well-being; unmet needs lead to
dread and anxiety.
Childhood
Language to 5 years
Parents are viewed as source of praise and acceptance. Shift to parataxic
mode; experiences are connected in sequence to each other. Primary zone
is anal. Gratification leads to positive self-esteem. Moderate anxiety leads
to uncertainty and insecurity; severe anxiety results in self-defeating
patterns of behavior
Juvenile
5–8 years
Shift to the syntaxic mode begins (thinking about self and others based on
analysis of experiences in a variety of situations). Opportunities for
approval and acceptance of others. Learn to negotiate own needs. Severe
anxiety may result in a need to control or in restrictive, prejudicial
attitudes.
Preadolescence
8–12 year
Move to genuine intimacy with friend of the same sex. Move away from
family as source of satisfaction in relationships. Major shift to syntaxic
mode occurs. Capacity for attachment, love, and collaboration emerges or
fails to develop.
Adolescence
Puberty to adulthood
Lust is added to interpersonal equation.
Need for special sharing relationship shifts to the opposite sex. New
opportunities for social experimentation lead to the consolidation of selfesteem or self-ridicule. If the self-system is intact, areas of concern expand
to include values, ideals, career decisions, and social concerns.
Erik Erikson and Psychosocial Stages of Development
In each stage, the person must complete a life task that is essential to his or her well-being and mental health. These tasks allow the
person to achieve life’s virtues: hope, purpose, fidelity, love, caring, and wisdom
Stage
Virtue
Trust vs. mistrust (infant)
Task
Hope
Viewing the world as safe and reliable; relationships as
nurturing, stable, and dependable
Will
Achieving a sense of control and free will
Purpose
Beginning development of a conscience; learning to manage
conflict and anxiety
Industry vs. inferiority (school age)
Competence
Emerging confidence in own abilities; taking pleasure in
accomplishments
Identity vs. role confusion (adolescence)
Fidelity
Formulating a sense of self and belonging
Intimacy vs. isolation (young adult)
Love
Forming adult, loving
attachments to others
Generativity vs. stagnation (middle
adult)
Ego integrity vs. despair (maturity)
Care
Being creative and productive; establishing the next generation
Wisdom
Accepting responsibility for oneself and life
Autonomy vs. shame and

Jean Piaget and Cognitive Stages of Development
Jean Piaget explored how intelligence and cognitive functioning develop in children. He believed that human intelligence progresses
through a series of stages based on age, with the child at each successive stage demonstrating a higher level of functioning than at
previous stages. In his schema, Piaget strongly believed that biologic changes and maturation were responsible for cognitive
development.
Therapeutic Community or Milieu. Sullivan envisioned the goal of treatment as the establishment of satisfying interpersonal
relationships. The therapist provides a corrective interpersonal relationship for the client. Sullivan coined the term participant
observer for the therapist’s role, meaning that the therapist both participates in and observes the progress of the relationship.
-
Piaget’s four stages of cognitive development are as follows:
1. Sensorimotor—birth to 2 years: The child develops a sense of self as separate from the environment and the concept of object
permanence, that is, tangible objects do not cease to exist just because they are out of sight. He or she begins to form mental images.
It involved client’s interactions with one another including practicing interpersonal relationships skills, giving one another
feedback about behavior, and working cooperatively as a group to solve day-to-day problems.
Milieu therapy was one of the primary modes of treatment in the acute hospital setting. In today’s health care environment,
however, inpatient hospital stays are often too short for clients to develop meaningful relationships with one another.
Therefore, the concept of milieu therapy receives little attention. Management of the milieu, or environment, is still a
primary role for the nurse in terms of providing safety and protection for all clients and promoting social interaction.
------------------------------------------------------------------------------------------------------------------------------------------------------------
2. Preoperational—2 to 6 years: The child develops the ability to express self with language, understands the meaning of symbolic
gestures, and begins to classify objects.
Hildegard Peplau: Therapeutic Nurse–Patient Relationships
3. Concrete operations—6 to 12 years: The child begins to apply logic to thinking, understands spatiality and reversibility, and is
increasingly social and able to apply rules; however, thinking is still concrete.
Hildegard Peplau was a nursing theorist and clinician who built on Sullivan’s interpersonal theories and also saw the role of the
nurse as a participant observer. Peplau developed the concept of the therapeutic nurse–patient relationship, which includes four
phases: orientation, identification, exploitation, and resolution
4. Formal operations—12 to 15 years and beyond: The child learns to think and reason in abstract terms, further develops logical
thinking and reasoning, and achieves cognitive maturity.
------------------------------------------------------------------------------------------------------------------------------------------------------------
-
During these phases, the client accomplishes certain tasks and makes relationship changes that help the healing process
Stage
Orientation
Identification
Tasks
The orientation phase is directed by the nurse and involves engaging the client in treatment, providing
explanations and information, and answering questions.
------------------------------------------------------------------------------------------------------------------------------------------------------------
Patient’s problems and needs are clarified. Patient asks questions. Hospital routines and expectations are
explained. Patient harnesses energy toward meeting problems. Patient’s full participation is elicited
Abraham Maslow: Hierarchy of Needs Abraham
The identification phase begins when the client works interdependently with the nurse, expresses feelings,
and begins to feel stronger.
Patient responds to persons he or she perceives as helpful. Patient feels stronger. Patient expresses
feelings. Interdependent work with the nurse occurs. Roles of both patient and nurse are clarified
HUMANISTIC THEORIES
Maslow studied the needs or motivations of the individual. Maslow formulated the hierarchy of needs, in which he used a pyramid
to arrange and illustrate the basic drives or needs that motivate people.


Exploitation
Resolution
In the exploitation phase, the client makes full use of the services offered.
Patient makes full use of available services. Goals such as going home and returning to work emerge.
Patient’s behaviors fluctuate between dependence and independence
In the resolution phase, the client no longer needs professional services and gives up dependent behavior.
The relationship ends.
Patient gives up dependent behavior. Services are no longer needed by patient. Patient assumes power to
meet own needs, set new goals, and so forth.


The most basic needs—the physiologic needs of food, water, sleep, shelter, sexual expression, and freedom from pain—
must be met first.
The second level involves safety and security needs, which include protection, security, and freedom from harm or
threatened deprivation.
The third level is love and belonging needs, which include enduring intimacy, friendship, and acceptance.
The fourth level involves esteem needs, which include the need for self-respect and esteem from others. The highest level
is self-actualization, the need for beauty, truth, and justice.
Maslow used the term self-actualization to describe a person who has achieved all the needs of the hierarchy and has developed his
or her fullest potential in life. Few people ever become fully self-actualized.
Carl Rogers: Client-Centered Therapy
Roles of the Nurses in the Therapeutic Relationship. Peplau also wrote about the roles of the nurses in the therapeutic relationship
and how these roles help meet the client’s needs. The primary roles she identified are as follows:





Stranger—offering the client the same acceptance and courtesy that the nurse would to any stranger
Resource person—providing specific answers to questions within a larger context • Teacher—helping the client learn either
formally or informally
Leader—offering direction to the client or group
Surrogate—serving as a substitute for another, such as a parent or sibling
Counselor—promoting experiences leading to health for the client, such as expression of feelings
Four Levels of Anxiety. Peplau defined anxiety as the initial response to a psychic threat. She described four levels of anxiety:
mild, moderate, severe, and panic
Mild
Moderate
Severe
Panic
Sharpened senses
Increased motivation
Alert

Carl Rogers focused on the therapeutic relationship and developed a new method of client-centered therapy. Rogers was one of the
first to use the term client rather than patient. Client-centered therapy focuses on the role of the client, rather than the therapist, as
the key to the healing process.
Rogers believed that each person experiences the world differently and knows his or her own experience best (Rogers, 1961).
According to Rogers, clients do “the work of healing,” and within a supportive and nurturing client–therapist relationship, clients
can cure themselves. Clients are in the best position to know their own experiences and make sense of them, to regain their selfesteem, and to progress toward self-actualization.
The therapist takes a person-centered approach, a supportive role, rather than a directive or expert role, because Rogers viewed the
client as the expert on his or her life. The therapist must promote the client’s self-esteem as much as possible through three central
concepts:
•
•
•
Unconditional positive regard—a non-judgmental caring for the client that is not dependent on the client’s behavior
Genuineness—realness or congruence between what the therapist feels and what he or she says to the client
Empathetic understanding—in which the therapist senses the feelings and personal meaning from the client and
communicates this understanding to the client
--------------------------------------------------------------------------------------------------------------------------------------------------------Treatment Modalities
Individual Psychotherapy - method of bringing about change in a person by exploring his or her feelings, attitudes, thinking, and
behavior. It involves a one-to-one relationship between the therapist and the client.
Group Therapy- A group is a number of persons who gather in a face-to-face setting to accomplish tasks that require cooperation,
collaboration, or working together. It includes family therapy, education groups, support groups, and self-help groups
Complementary and Alternative Therapies
•
•
Complementary medicine includes therapies used with conventional medicine practices (the medical model).
Alternative medicine includes therapies used in place of conventional treatment.
Variety of complementary and alternative therapies
•
Alternative medical systems - include homeopathic medicine and naturopathic medicine in Western cultures, and
traditional Chinese medicine, which includes herbal and nutritional therapy, restorative physical exercises (yoga and tai
chi), meditation, acupuncture, and remedial massage.
•
Mind-Body Interventions - include meditation, prayer, mental healing, and creative therapies that use art, music, or dance.
•
Biologically based therapies - use substances found in nature, such as herbs, food, and vitamins. Dietary supplements,
herbal products, medicinal teas, aromatherapy, and a variety of diets are included
•
Manipulative and body based therapies - are based on manipulation or movement of one or more parts of the body, such
as therapeutic massage and chiropractic or osteopathic manipulation.
•
Energy therapies - include two types of therapy: biofield therapies, intended to affect energy fields that are believed to
surround and penetrate the body, such as therapeutic touch, qi gong, and Reiki, and bioelectric-based therapies involving
the unconventional use of electromagnetic fields, such as pulsed fields, magnetic fields, and alternating current or direct
current fields. Qi gong is part of Chinese medicine that combines movement, editation, and regulated breathing to enhance
the flow of vital energy and promote healing. Reiki (which in Japanese means “universal life energy”) is based on the
belief that when spiritual energy is channeled through a Reiki practitioner, the patient’s spirit and body are healed.
Psychiatric Rehabilitation - involves providing services to people with severe and persistent mental illness to help them to live in
the community. These programs are often called community support services or community support programs.
These programs assist clients with activities of daily living, such as transportation, shopping, food preparation, money
management, and hygiene. Social support and interpersonal relationships are recognized as a primary need for successful
community living.

Anger, Hostility, and Aggression
Anger
Anger results when a person is frustrated, hurt, or afraid. Handled appropriately and expressed assertively, anger can be a positive
force that helps a person resolve conflicts, solve problems, and make decisions.
Although anger is normal, it is often perceived as a negative feeling. Possible consequences are physical problems such as migraine
headaches, ulcers, or coronary artery disease, and emotional problems such as depression and low self-esteem. Anger that is
expressed inappropriately can lead to hostility and aggression.
Assertive communication uses “I” statements that express feelings and are specific to the situation, for example, “I feel angry
when you interrupt me,” or “I am angry that you changed the work schedule without talking to me.”
Hostility, also called verbal aggression, is an emotion expressed through verbal abuse, lack of cooperation, violation of rules or
norms, or threatening behavior (Schultz & Videbeck, 2013)
Physical aggression is behavior in which a person attacks or injures another person or destroys property.

Definition
Signs, Symptoms, and Behaviors
Triggering
An event or circumstances in the
environment initiates the client’s response,
which is often anger or hostility.
The client’s responses represent escalating
behaviors that indicate movement toward a
loss of control.
Restlessness, anxiety, irritability, pacing, muscle tension,
rapid breathing, perspiration, loud voice, anger
Escalation
Crisis
During an emotional and physical crisis,
the client loses control.
Recovery
The client regains physical and emotional
control.
The client attempts reconciliation with
others and returns to the level of
functioning before the aggressive incident
and its antecedents.

screaming, inability to communicate clearly
Lowering of voice; decreased muscle tension; clearer,
more rational communication; physical relaxation
Remorse; apologies; crying; quiet, withdrawn behavior
Acting out - an immature defense mechanism by which the person deals with emotional conflicts or stressors through actions rather
than through reflection or feelings. The person engages in acting-out behavior, such as verbal or physical aggression, to feel
temporarily less helpless or powerless.
Etiology

Neurobiologic Theories - Low serotonin levels increased activity of dopamine and norepinephrine increased activity of
dopamine and norepinephrine structural damage to the limbic system and the frontal and temporal lobes

Psychosocial Theories - Failure to develop impulse control and ability to delay gratification.
Cultural Considerations
In certain cultures, anger expression has been seen as rude and disrespectful. Some culture-bound syndromes involve aggressive,
agitated, or violent behaviour.
Treatments and Medications
The treatment of aggressive clients often focuses on treating the underlying or comorbid psychiatric diagnosis

Ethical Dilemmas in Mental Health
Many dilemmas in mental health involve the client’s right to self- determination and independence (autonomy) and concern for the
“public good” (utilitarianism). Examples include the following:
•
•
•
Are psychotic clients necessarily incompetent, or do they still have the right to refuse hospitalization and medication?
Should a client who is loud and intrusive to other clients on a hospital unit be secluded from the others?
Should physicians break confidentiality to report clients who drive cars at high speeds and recklessly?
Points to Consider When Confronting Ethical Dilemmas
•
Talk to colleagues or seek professional supervision. Usually, the nurse does not need to resolve an ethical dilemma alone.
•
Spend time thinking about ethical issues, and determine what your values and beliefs are regarding situations before they
occur.
•
Be willing to discuss ethical concerns with colleagues or managers. Being silent is condoning the behavior.
