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, 1998) note that a theory of depression should explain the following:

1. Behavioral and cognitive changes2. Common causes of depression

12

Theory of Depression

3. Gender differences

13

14

Theory of Depression

4. Depressive episodes self-terminate.

5. Stressful events often precede depression.

6. Depression is increasing, especially in the teens.

Social-Cognitive Perspective

The social-cognitive perspective suggests that depression arises partly from self-defeating

beliefs and negative explanatory styles.

28

Negative Thoughts and Moods

Explanatory style plays a major role in becoming depressed.

29

Depression Cycle

1. Negative stressful events.

2. Pessimistic explanatory style.

3. Hopeless depressed state.

4. These hamper the way the individual thinks and acts, fueling personal rejection.
