Other Axis I Disorders Eating Disorders Sleep Disorders Disorders of childhood and adolescence Autism, ADHD, Tourette’s, Conduct Disorder Sexual and Gender Identity Disorders Cognitive Disorders Impulse Control Disorders Adjustment Disorders VIII. Personality Disorders Diagnosed on Axis II Stem from the gradual development of inflexible and distorted personality and behavioral patterns that result in persistently maladaptive ways of relating to the world Ego-syntonic…not a problem for the person A problem for others Resistant to treatment (only behavioral) FOCUS Antisocial, Narcissistic, OCPD Symptoms of Obsessive Compulsive Personality Disorder OCPD symptoms tend to appear early in adulthood and are defined by inflexibility, close adherence to rules, anxiety when rules are transgressed, and unrealistic perfectionism.

Psychopathology & The Law Competence to Stand Trial Can individual participate in own defense at time of trial?

Could not determine right from wrong Determined by judge before actual trial Difficult to prove, but prevalent in media Sent for treatment, then released *Insanity is a LEGAL term…! More Legal Issues…State-level Guilty but Mentally Ill Alternative to insanity plea in some states Adopted by Pennsylvania… 1st trial determines guilt or innocence 2nd trial determines sanity or insanity Sent for treatment, then to prison to complete sentence…get treatment as well as punishment TYPES OF PSYCHOTHERAPY — A number of types of psychotherapy are used to treat psychological disorders: •Cognitive therapy identifies habitual ways in which patients distort information (e.g. automatic thoughts) and teaches patients to identify, evaluate, and respond to their dysfunctional thoughts and beliefs, using a variety of techniques to change thinking, mood, and behavior. Cognitive therapy is a structured, goal oriented, problem focused, and time limited intervention. TYPES OF PSYCHOTHERAPY •Behavioral therapy attempts to alter behavior by systematically changing the environment that produces the behavior. Behavioral changes are believed to lead to changes in thoughts and emotions. •Exposure-based behavioral treatments utilize gradual, systematic, repeated exposure to the feared object or situation to allow patients with anxiety disorders to become desensitized to the feared stimulus. TYPES OF PSYCHOTHERAPY •Cognitive Behavioral therapy (CBT) combines principles of both behavioral and cognitive therapy, focusing simultaneously on the environment, behavior, and cognition. Cognitive behavioral therapy is also structured, goal directed, problem focused. Patients learn how their thoughts contribute to symptoms of their disorder and how to change these thoughts. Increased cognitive awareness is combined with specific behavioral techniques. TYPES OF PSYCHOTHERAPY •Problem Solving therapy, a short-term, cognitive behavioral intervention, teaches a systematic method for solving current and future problems. Patients acquire new skills for successfully resolving interpersonal difficulties. These skills include the following sequential steps: 1) Problem definition; 2) Goal setting; 3) Generating, choosing, and implementing solutions; and 4) Evaluating outcomes. TYPES OF PSYCHOTHERAPY •Interpersonal therapy addresses issues such as grief, role transitions, interpersonal role disputes, and interpersonal deficits as they relate to the patient's current symptoms. •Family therapy attempts to correct distorted communications and relationships as a means of helping the entire family, including the identified patient. In patients with serious mental illness, such as schizophrenia, family therapy helps family members learn about the disorder, solve problems, and cope more constructively with the patient's illness. TYPES OF PSYCHOTHERAPY •Psychoeducation provides patients with information about their diagnosis, its treatment, how to recognize signs of relapse, relapse prevention, and strategies to cope with the reality of prolonged emotional or behavioral difficulties. •The goal of psychoeducation is to reduce distress, confusion, and anxiety within the patient and/or the patient's family to facilitate treatment compliance and reduce the risk of relapse. •Psychoeducation is often particularly helpful for patients and the families of patients with chronic, severe psychiatric disorders such as schizophrenia and bipolar disorder.
