. The odds ratios
(OR) of predicting bipolar disorder type I, II, mania and hypomania
were calculated using each of the 15 questions about manic and
hypomanic episodes according to WHO-CIDI 3.0. The respondents
diagnosed with bipolar disorder were compared with those who were
diagnosed with major depressive disorder or anxiety disorders. The
ORs of each question ranged from 0.75 to 4.80. Four questions which
had significant ORs were chosen for the items of WBI. These questions
were related to the signs and symptoms of “psychomotor agitation”
(OR¼4.05 [95% CI: 1.13–14.57]), “increase in goal-directed activity”
(OR¼3.70 [95% CI: 1.08–12.66]), “excessive involvement in pleasurable
activities that have a high potential for painful consequences”
(OR¼4.38 [95% CI: 1.21–15.78]), and “more talkative than usual or
pressure to keep talking” (OR¼4.80 [95% CI: 1.38–16.65]).
