Chapter 16: DEVELOPMENTAL
PSYCHOPATHOLOGY
Abnormality
– Statistical deviance
– Maladaptiveness
• Interferes with personal and social life
• Poses danger to self or others
– Personal distress
– DSM-IV diagnostic criteria (APA)

Developmental Aspects
Developmental psychopathology – study of
origins and course of maladaptive behavior
• Disorders and
not disease (you have it or
you don’t)
– A pattern of maladaption, not defects
• Social and Age Norms
• Developmental issues
– Nature/Nurture (origin of maladaptive
behaviors)
– Risk factors
– Prediction

The Diathesis-Stress Model
• Diathesis – predisposition or vulnerability
•
•
•
•
•
(genetic, cognitive, personality)
Stress – environmental pressure
Interaction of genes and environment
Example: Depression
– Genetic vulnerability
– Environmental trigger(s)
Not specific stressors for specific disorders
“Bad things have bad effects for some people
some of the time”
Life-Span Human Development, Fifth Edition, Carol K. Sigelman and Elizabeth A. Rider

• Extreme stress and high vulnerability (severe

disorder)
Extreme stress and high resiliency (mild
disorder)
Low stress and high vulnerability (mild
disorder)
Low stress and high resiliency (no disorder)

Attention-Deficit Hyperactivity Disorder
• DSM-IV Criteria: some combination of
•
•
•
– Inattention
– Impulsivity
– Hyperactivity
– More boys; 3-5% of US kids
– Comorbidity common
Overactive behavior wanes with age
Attentional, adjustment problems remain
Most well adjusted in adulthood

ADHD-Causes and Treatment
• Neurological: low Dopamine, other NT’s
•
•
•
– Differential processing
– Underactivity in motor area
Genetic predisposition; Environmental stress
70% helped by stimulants
– Overprescription a problem
Most successful if combined with behavioral
treatment
Life-Span Human Development, Fifth Edition, Carol K. Sigelman and Elizabeth A. Rider
Chapter 16
Depression
• Childhood
•
– Somatic symptoms
– Psychotherapy, medication effective
– Nature/Nurture question
Adolescence
– Often related to childhood symptoms
Life-Span Human Development, Fifth Edition, Carol K. Sigelman and Elizabeth A. Rider
Chapter 16
Adolescence
• Storm and stress
•
•
– Only about 20%
– Heightened vulnerability to psych disorders
Alcohol and drugs are problems
Eating disorders
– Anorexia nervosa; more girls (3/1)
– Bulemia nervosa; binge-purge
– Some genetic predisposition; stress also
– Psychological treatment usually successful

Adolescent Depression and Suicide
• 35% depressed; 7% diagnosable
•
– Cognitive symptoms
– Behavioral acting out
– Genetic link
– Environmental triggers
Suicide 3rd leading cause of death
– Males commit 3:1 compared to females
– Females attempt 3:1 compared to males

Adulthood
• Rates of disorder decrease after age 18
• Depression
– Elderly less vulnerable to major depression
– Concern with elderly
• Depression often related to health
• 15% have some symptoms
• 1-3% diagnosable
• Difficult to diagnose
– More women (2:1)

Depression and Dementia
•
•
•
•
Many undiagnosed and untreated
Elderly can benefit, should NOT be excluded
from treatment
Dementia: progressive deterioration of neural
functioning associated with memory impairment,
declines in tested intellectual ability, poor
judgment, difficulty thinking abstractly and often
personality changes
Alzheimer’s Disease
– Leading cause of dementia
– Progressive and irreversible
Life-Span Human Development, Fifth Edition, Carol K. Sigelman and Elizabeth A. Rider
Chapter 16
Causes of Alzheimer’s
• Senile plaques – masses of dying neural
material with toxic protein called beta amyloid
• The plaque injures/kills neurons
• Neurofibrillary tangles – twisted strands of
neural material
Early-onset form (prior to age 60)-genetic links
Late-onset form (after age 70)-family history not
predictive
