2) Behaviour is maladaptive Impaired functioning Inability to meet responsibilities
3) Socially Deviant Behaviour is unusual, “not normal”
Classification DSM-IV, p. 580 text Why Classify?

Where is the dividing line between normal and abnormal behavior?
Deviation from statistical average
Deviation from cultural/societal average
1. Classification (cont’d)
Older Distinction: Neurotic vs. Psychotic
Neurotic: Distressing problem but person is still coherent and can
function socially (once acute phase of disorder is treated). E.g. most disorders discussed today
Psychotic: More bizarre, involving delusions or hallucinations.
Individual has impaired thought processes and cannot function socially. Treatment is long term
E.g. schizophrenia (next week)
2. Anxiety Disorders
Anxiety: Fear in situations that pose no objective threat 3 components:
A) Cognitive: Extreme/chronic worry; fear of harm
B) Physiological: Muscle tension, increased heart rate and blood pressure
C) Behavioural: Shaking, jumpiness, pacing, avoidance

3. Somatoform Disorders Hypochondriasis:
4-9% in medical practice Inordinate preoccupation with health and illness excessive anxiety about having a disease http://www.youtube.com/watch?v=lkIQ39538Ig&feature=related http://www.youtube.com/watch?v=tV_ORdpOK3g
Somatization Disorder: (1-2% women) History of diverse physical complaints for which there is NO
organic basis Long medical history of treatments for minor physical
ailments
4. Dissociative Disorders Multiple Personality Disorder (very rare)
Presence of at least 2 distinct personalities within the same individual
Leads to sudden changes in identity and consciousness
Each personality has its unique style and may unaware of the existence of the other personalities
Often related to severe abuse in early childhood
5. Mood Disorders
Depression Lifetime prevalence rates
20% in women; 10% in men Why more common in women?
Cost of caring Greater burden due to nurturing roles Also more affected by disruptions in relational ties
Exposure to higher levels of stress Victimization, abuse
Ruminative cognitive style as opposed to distraction or taking action Perpetuates negative mood
More likely to report symptoms
Seasonal Affective Disorders (SAD) Depressive symptoms related to physiological consequences of shorter winter
days Treatable with light therapy
5. Theories of Depression Biological predisposition
Concordance rates in twins: Identical: 65% Fraternal: 15%
G X E models (interaction of genetic and environmental contributors) Cognitive perspective
Beck: Negative (dysfunctional) attitudes Seligman: Attribution Theory
How do you explain your circumstances? Internal vs external Stable vs unstable Global vs specific
Depression: internal, stable, global attributions for negative events Diathesis-stress models
Depression results from an interaction between personality and negative life events
Dependency and vulnerability to loss Self-Criticism/Perfectionism and vulnerability to perceived failure
Cognitive Risk and Depression Featured Study p. 629
Students with dysfunctional attitudes and depressive attributional style were more likely to become depressed over 2 year period.
5. Mood Disorders (cont’d)
Bipolar Disorders: Periods of depression alternate with manic episodes Mania:
abnormally elevated mood, inflated self-esteem, pressure of speech, increased energy, decreased need for sleep, over-activity, lack of inhibition and impaired judgment

environmental determinants

future Provide support for treatment
