Unit 6 – Adjustment & Breakdown Psychological Disorders
Psychological Disorders • Normal or Abnormal? • What most people (majority) do is normal Deviation is abnormal • Getting along on the world is normal Failure to adjust physically, emotionally or psychologically is abnormal • Striving for ideal psychological functioning (self-actualization) is normal
Abnormal Behavior • Is normal better than abnormal? • Oppression, stonings, tax evasion, speeding, smoking, drinking, late assignments, skipping class, … • Why study abnormal behavior? • Harmful behaviors (crime, drug use, violence) might be changed / stopped (i.e. BAU)
Abnormal Behavior • Depends on situation - where/ when ??
Abnormal Behavior • Depends on situation - where/ when ?? • (comfort in environment, clothes for season / venue, urgency) • Cultural differences ?? • (hand holding, men kissing, bowing, evil spirits) • Occasional abnormal behavior does not mean a psychological disorder (TRY IT)
Failure to adjust • Does abnormal behavior cause difficulty getting along in the world? • (can’t leave house…can’t work) • Everyone strives toward ideal functioning = self-actualization
Sanity • Legal definition – far too simple for psychologists • “most people labelled mentally ill are not ill at all” (Szasz)…simply have problems with daily living • Convenient to label people ill and hospitalize them
Classification • DSM (Diagnostic and Statistical Manual of Mental Disorders) – classify mental illness • DSM IV uses 5 major axes (dimensions): • Explicitly defined categories (mood, schizophrenia & other psychotic, eating…) • Developmental or long standing personality disorders • Physical disorders or medical conditions • Measures stress level • Highest level of adaptive functioning
Mental Illness • Who is affected? • Mental illness indirectly affects all Canadians at some time through a family member, friend or colleague. • 20% of Canadians will personally experience a mental illness in their lifetime. • Mental illness affects people of all ages, educational and income levels, and cultures. • Approximately 8% of adults will experience major depression at some time in their lives. • About 1% of Canadians will experience bipolar disorder (or “manic depression”).
Mental Illness • How common is it? • Schizophrenia affects 1% of the Canadian population. • Anxiety disorders affect 5% of the household population, causing mild to severe impairment. • Suicide accounts for 24% of all deaths among 15-24 year olds and 16% among 25-44 year olds. • Suicide is one of the leading causes of death in both men and women from adolescence to middle age. • The mortality rate due to suicide among men is four times the rate among women. http://www.cmha.ca/media/fast-facts-about-mental-illness/
The Issues • How many undiagnosed / misdiagnosed? • Problem getting better or worse? Why? • Are awareness campaigns successful? • Why is there still such a stigma?

Mood Disorders • Types ?? • Major depressive disorder – feelings of worthlessness and diminished pleasure • Case study: Kari • Bipolar disorder – cycle between alternating phases: manic (euphoria / frantic action) and depressive (deep despair) • Case study: Moira
Mood Disorders • Seasonal Affective Disorder (SAD) – melatonin high (sleep) + serotonin low (mood) • Post partum depression (PPD) – 3-4 weeks after birth, cause may be hormone shift, may lead to other depressive disorders
Mood Disorders • Causes ?? • Self-esteem, social support, coping with stress • Draw illogical conclusions about self (Beck) • Learned helplessness (Seligman) • No control – useless to try • Reduced serotonin and/or noradrenaline • Therefore, both biological & psychological • Risk of suicide (3rd leading cause of death for teens)
