Assessment method [1]

The neuropsychiatric symptoms of schizophrenia were assessed using the 30-item PANSS scale, which provides a total score (sum of the scores for all 30 items) and scores for 3 subscales: the 7-item positive-symptom (P) subscale, the 7-item negative-symptom (N) subscale, and the 16-item general-psychopathology symptom (G) subscale. Each item is rated on a scale from 1 (absent) to 7 (extreme). The PANSS total score ranges from 30 (absent disease)-210 (more severe neuropsychiatric symptoms of schizophrenia).

CGI-S is defined as clinician-rated scale that assesses the severity of mental illness on a scale of 0 to 7. Considering total clinical experience, a participant was assessed on severity of mental illness at the time of rating according to:1: normal, not at all ill; 2: borderline mentally ill; 3: mildly ill; 4: moderately ill; 5: markedly ill; 6: severely ill; 7: among the most extremely ill patients. A higher score implies a more severe condition.

The Personal and Social Performance (PSP) scale assesses degree of a participant's dysfunction within 4 domains of behavior: 1) socially useful activities, 2) personal and social relationships, 3) self-care, and 4) disturbing and aggressive behavior. Each domain was assessed on a 6-point scale, from 1 (absent) to 6 (very severe) (1 = absent, 2 = mild, 3 = manifest, 4 = marked, 5 = severe, and 6 = very severe). PSP total score was calculated as sum of all the domain scores and ranges from 1 to 100. Participants with score of 71 to 100 have mild degree of difficulty; from 31 to 70, varying degrees of disability; less than or equal to 30, functioning so poorly as to require intensive supervision. Higher score indicates better performance.

Assessment method [4]

Symptomatic remission was defined as achieving intensity level of mild or moderate on PANSS scale by all 8 items as the determinants for symptomatic remission: delusions, unusual thought content, hallucinatory behavior, conceptual disorganization, mannerisms/posturing, blunted affect, social withdrawal, lack of spontaneity. The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self). The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent), 2 (minimal), 3 (mild), 4 (moderate), 5 (moderately severe), 6 (severe) and 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity.

TSQM-9 consists of 9 questions to assess patients' satisfaction with medication using a range of responses from 1 (extremely dissatisfied) to (7 extremely satisfied). This patient reported outcome provides scores on three parts: effectiveness, convenience, and global satisfaction. The sum of the 9-questions were calculated and used for analysis. The total score ranges from 0 to 63, with higher scores indicating better treatment satisfaction.

Number of Participants With Symptoms of Akathisia Assessed Using Barnes Akathisia Rating Scale (BARS) Score

Assessment method [8]

BARS is used to rate observable, restless movements of drug induced akathisia and subjective awareness of restlessness and any distress associated with the akathisia. BARS consists of the following 4 items: objective assessment of akathisia symptoms, subjective assessment of the participants's awareness of inner restlessness, distress restlessness, and global clinical assessment of akathisia. First three items are rated on a 4-point scale ranging from 0 (no abnormal movements or absence of inner restlessness or no distress) to 3 (severe akathisia or awareness of intense compulsion to move most of the time or severe distress). The last item, the global clinical assessment of akathisia, is rated on a 6-point scale, ranging from 0 (no evidence of akathisia) to 5 (severe akathisia).

Assessment method [9]

AIMS is a 14-item scale. Items 1 to 8 are rated on a 5-point scale ranging from 0 (no dyskinetic movements) to 4 (severe dyskinetic movements). Item 9 assesses the participant's incapacitation due to abnormal movements, and item 10 assesses the participant's awareness of the abnormal movements and associated distress. Items 9 and 10 are rated on 5-point scales ranging from 0 (none or no awareness) to 4 (severe or aware, severe distress). Items 11 to 14 are yes/no questions regarding the global judgement and dental status of the participant. The total score is the sum of the scores for the 14 items and the possible total score ranges from 0 to 44. A higher total score is indicative of more severe dyskinetic movements.
