Mean Change From Baseline in Simpson-Angus Neurologic Rating Scale (SAS) Total Score
Time Frame: Baseline, Week 32
The SAS scale is used to evaluate extrapyramidal symptoms (EPS) and consists of a list of 10 symptoms of Parkinsonism (gait, arm dropping, shoulder shaking, elbow rigidity, wrist rigidity, head rotation, glabella tap, tremor, salivation, and akathisia). Each item is rated on a 5-point scale, with a score of range of 0 (absence of symptoms) to 4 (severe condition). The SAS total score is the sum of the scores for all 10 items, possible total score is 0 to 40. Negative change from baseline indicates less symptoms.
Baseline, Week 32
Mean Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Movement Score
Time Frame: Baseline, Week 32
The AIMS assessment consists of 10 items describing symptoms of dyskinesia. Facial and oral movements (items 1 through 4), extremity movements (items 5 and 6), and trunk movements (item 7), dyskinesias (items 8 through 10). Each item is rated on a 5-point scale, with a score of 0 representing absence of symptoms (for item 10, no awareness), and a score of 4 indicating a severe condition (for item 10, aware/severe distress). AIMS movement score is the sum of the ratings for the first seven items with the possible total scores of 0 to 28. Negative change from baseline indicates less symptoms.
Baseline, Week 32
Mean Change From Baseline in Barnes Akathisia Rating Score (BARS) Global Score
Time Frame: Baseline, Week 32
The BARS consists of 4 items related to akathisia: objective observation of akathisia by the investigator, subjective feelings of restlessness by the participant, participant distress due to akathisia, and global evaluation of akathisia. The first 3 items are rated on a 4-point scale, with a score of 0 representing absence of symptoms and a score of 3 representing a severe condition. The global clinical evaluation is made on a 6-point scale, with 0 representing absence of symptoms and a score of 5 representing severe akathisia. Total BARS score ranges from 0 to 14 where lower scores indicate less symptoms and negative change from baseline indicate less symptoms.

Mean Change From Baseline in Positive and Negative Syndrome Scale Rating Criteria (PANSS) Total Score
Time Frame: Baseline, Week 32
The PANSS consisted of three subscales: a total of 30 symptom constructs. For each symptom construct, severity was rated on a 7-point scale, with a score of 1 (absence of symptoms) and a score of 7 (extremely severe symptoms). The PANSS total score was the sum of the rating scores for 7 positive scale items, 7 negative scale items, and 16 general psychopathology scale items from the PANSS panel. The PANSS total score ranged from 30 (best possible outcome) to 210 (worst possible outcome). Higher scores indicate worse condition. The PANSS was assessed for schizophrenia participants only.
Baseline, Week 32
Mean Change From Baseline in Clinical Global Impression - Severity Scale (CGI-S) Score
Time Frame: Baseline, Week 32
The CGI-S is a standardized, clinician-administered global rating scale that measures disease severity. To assess CGI-S, the rater or investigator answered the following question: "Considering your total clinical experience with this particular population, how mentally ill is the participant at this time?" Response choices include: 0 = not assessed; 1 = normal, not ill at all; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill participants. The cumulative score range is 0-7. A higher score on the CGI-S represents a higher severity of disease. The CGI-S scale was assessed for schizophrenia participants only.
Baseline, Week 32
Mean Change From Baseline in Clinical Global Impression - Improvement Scale (CGI-I) Score
Time Frame: Baseline, Week 32
The CGI-I scale is a clinician rated scale which assesses the improvement of illness for each participant. To assess CGI-I, the rater or investigator rated the participant's total improvement whether or not it is due entirely to drug treatment. All responses were compared with the participant's condition at baseline. Response choices include: 0 = not assessed, 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse. Scores range from 0 to 7. Higher scores indicate worse condition.
Baseline, Week 32
Mean Change From Baseline in Subjective Well-Being Under Neuroleptic Treatment-Short Form (SWN-S) Total Score
Time Frame: Baseline, Week 32
The participant's feeling of their own well-being was assessed using the 20-question SWN-S. The SWN-S was a validated self-report instrument that evaluated the participant's perception of well-being while receiving antipsychotic medication. The questionnaire consisted of 20 items (10 positive and 10 negative statements) and 5 subscales (mental functioning, social integration, emotional regulation, physical functioning, self-control) whose items followed in random order. For items marked with a '+', the response choices and scoring is not at all = 1, hardly at all = 2, a little = 3, somewhat = 4, much = 5, and very much = 6. For items marked with a '- ', the scoring is reversed; response choices and scoring are as follows: not at all = 6, hardly at all = 5, a little = 4, somewhat = 3, much = 2, very much = 1. SWN-S subscale score's each item was rated on a score of 1 (none) to 6 (severe), and total score ranged from 20 to 120, with higher scores indicating stronger subjective feeling
Baseline, Week 32
Mean Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
Time Frame: Baseline, Week 32
The MADRS is a diagnostic questionnaire used by clinician to assess the participant's severity of depression. This scale consists of 10 items each with 7 defined grades of severity on 0 to 6 scale (reported sadness, apparent sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts). MADRS total score is sum of 10 individual item scores ranging from 0-60 categorized as: 0 to 6: normal/symptoms absent, 7 to 19: mild depression, 20 to 34: moderate depression, and 35 to 60: severe depression. Higher score indicates more depressive symptoms. The MADRS was assessed for bipolar I disorder participants only.
Baseline, Week 32
Mean Change From Baseline in Young Mania Rating Scale (YMRS) Total Score
Time Frame: Baseline, Week 32
The YMRS is an 11-item, multiple-choice diagnostic questionnaire which psychiatrists use to assess the core symptoms of mania and is based on the participants subjective report of their condition. There are four items that are graded on a 0 to 8 scale (irritability, speech, thought content, and disruptive/aggressive behavior), while the remaining seven items are graded on a 0 to 4 scale. Total score is summed of 11 items. Total score range is from 0 to 60 and the higher score represent a worse outcome. The YMRS was assessed for bipolar I disorder participants only.
Baseline, Week 32
Mean Change From Baseline in Clinical Global Impression - Bipolar Version (CGI-BP) Severity of Illness Score
Time Frame: Baseline, Week 32
The CGI-BP scale refers to the global impression of the participants with respect to bipolar disorder. The scale rates the participant's severity of illness (CGI-BP-Severity: mania, depression, and overall bipolar illness) and change from preceding phase (CGI-BP change from preceding phase: mania, depression, and overall bipolar illness) based on a 7-point scale ranging from 1 (normal, not ill) to 7 (very severely ill). A negative change score signifies improvement. The CGI-BP was assessed for bipolar I disorder participants only.
