Group	Intervention	Description
1	Aripiprazole	-
2	placebo	-

Primary Outcome Measures

Name	Time	Method
Young Mania Rating Scale (YMRS)	Day1, Day21	Using LOCF datasets, change in YMRS total score from baseline (Day 1) to endpoint (Day 21) was evaluated through analysis of covariance(ANCOVA).; YMRS is composed of 11 evaluation items with 5 rating levels each. Items rated on a scale of 0 to 4 (comprising 5 rating levels of one point each) are 1) elevated mood, 2) increased motor activity/energy, 3) sexual interest, 4) sleep, 7) language-thought disorder, 10) appearance, and 11) insight. Items rated on a scale of 0 to 8 (comprising 5 rating levels of two points each) are 5) irritability, 6) speech (rate and amount), 8) content, and 9) disruptive-aggressive behavior.; YMRS ranges from 0 (best possible outcome) to 60 (worst possible outcome).

Secondary Outcome Measures

Name	Time	Method
Clinical Global Impression - Bipolar Version (CGI-BP), Severity of Illness Score (Mania)	Day1, Day21	CGI-BP severity of illness is a scale for overall evaluation of the severity of bipolar disorder; it comprises 3 components-mania, depression, and overall bipolar illness.; CGI-BP severity of illness score (mania) ranges form 1 (normal, not ill) to 7 (very severely ill).; Using LOCF datasets, change in CGI-BP severity of illness score (mania) from baseline (Day 1) to endpoint (Day 21) was evaluated through ANCOVA.
