The 1996 Beck Depression Inventory-II was administered to 120 outpatients diagnosed with DSM-IV-TR bipolar I disorders who had recently experienced manic, mixed, or depressed episodes. A focused contrast supported the hypothesis that the mean Beck-II total score for the 40 patients with depressed episodes (M=34.1, SD = 13.2) was higher than the mean Beck-II total score for the 40 patients with mixed episodes (M=25.9, SD= 13.6) which was, in turn, higher than the mean Beck-II total score for the 40 patients with manic episodes (M= 11.7, SD=7.8, p<.001). The Beck Depression Inventory-II appears to be useful for measuring self-reported depression in patients with bipolar I disorders.

Bipolar Disorder01:30

Bipolar Disorder

Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.
Self-Report Tests of Personality01:22

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Depressive Disorders: MDD and Dysthymia

Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men.
