20. Explaining Mood Disorders Since depression is so prevalent worldwide, investigators want to develop a theory of depression that will suggest ways to treat it. Lewinsohn et al., (1985, 1995) note that a theory of depression should explain the following: 1.Behavioral and cognitive changes 2.Common causes of depression

21. Theory of Depression 3.Gender differences

22. Theory of Depression 4.Depressive episodes self-terminate. 5.Depression is increasing, especially in the teens. Post-partum depression Desiree Navarro/ Getty Images

23. Mood Disorders Depression often triggered by stress However, unlikely that stress alone causes depression Some people are more vulnerable to depression – biological vulnerability; developmental vulnerability The Etiology of Depression

24. Biological Perspective Genetic Influences: Mood disorders run in families. The rate of depression is higher in identical (50%) than fraternal twins (20%). Linkage analysis and association studies link possible genes and dispositions for depression. Jerry Irwin Photography

25. Neurotransmitters & Depression Post-synaptic Neuron Pre-synaptic Neuron Norepinephrine Serotonin A reduction of norepinephrine and serotonin has been found in depression. Drugs that alleviate mania reduce norepinephrine.

28. Mood Disorders When people experience a decline in rewards – particularly social rewards – they can enter a downward spiral of decreasing rewards that leads to depression. Theoretical Problem: Does decline in rewards cause depression, or does depression cause decline in rewards? Psychological Views of Depression Behavioral Views

29. Explanatory Style Explanatory style plays a major role in becoming depressed.

31. Mood Disorders Negative Thinking Maladaptive attitudes often rooted in childhood –E.g.: “If I make a mistake, I’m worthless” These attitudes develop into entrenched schemas Stress triggers negative schemas Psychological Views of Depression Cognitive Views

32. Mood Disorders Negative Thinking Controlled by these schemas, self, present & future perceived negatively Schemas lead to “automatic thoughts” that continuously confirm negative perceptions Schemas lead to “thinking errors” –E.g.: “Nobody cares about me” Psychological Views of Depression Cognitive Views

33. Mood Disorders Negative Thinking Considerable research supports the link between depression and: –Maladaptive attitudes; negative schemas; thinking errors; & automatic thoughts However, do cognitive patterns cause depression – or are they caused by it? Psychological Views of Depression Cognitive Views

34. Systems Approach
