REVIEW Depressive Disorders and Bipolar Disorder

LEARNING OBJECTIVES

RETRIEVAL PRACTICE Take a moment to answer each of these Learning Objective Questions (repeated here from within this section). Then click the 'show answer' button to check your answers. Research suggests that trying to answer these questions on your own will improve your long-term retention (McDaniel et al., 2009).

51-1 How do major depressive disorder, persistent depressive disorder, and bipolar disorder differ?

A person with major depressive disorder experiences two or more weeks with five or more symptoms, at least one of which must be either (1) depressed mood or (2) loss of interest or pleasure. Persistent depressive disorder includes a mildly depressed mood more often than not for at least two years, along with at least two other symptoms. A person with the less common condition of bipolar disorder experiences not only depression but also mania—episodes of hyperactive and wildly optimistic, impulsive behavior.

51-2 How can the biological and social-cognitive perspectives help us understand depressive disorders and bipolar disorder?

The biological perspective on depressive disorders and bipolar disorder focuses on genetic predispositions and on abnormalities in brain structures and function (including those found in neurotransmitter systems). The social-cognitive perspective views depression as an ongoing cycle of stressful experiences (interpreted through negative beliefs, attributions, and memories) leading to negative moods and actions and fueling new stressful experiences.

51-3 What factors increase the risk of suicide and what do we know about nonsuicidal self-injury?

Suicide rates differ by nation, race, gender, age group, income, religious involvement, marital status, and (for gay and lesbian youth, for example) social support structure. Those with depression are more at risk for suicide than others are, but social suggestion, health status, and economic and social frustration are also contributing factors. Environmental barriers (such as jump barriers) are effective in preventing suicides. Forewarnings of suicide may include verbal hints, giving away possessions, withdrawal, preoccupation with death, and discussing one’s own suicide.
     Nonsuicidal self-injury (NSSI) does not usually lead to suicide but may escalate to suicidal thoughts and acts if untreated. People who engage in NSSI do not tolerate stress well and tend to be self-critical, with poor communication and problem-solving skills.
