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) to 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity.

The PSP is 100-point validated clinician-rated scale that assesses degree of difficulty in 4 areas of functioning: socially useful activities, personal and social relationships, self-care, disturbing and aggressive behaviors rated on 6-point scale (1=absent to 6=very severe).Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning, with higher transformed score indicating better function. Total score is divided into 3 levels: 71-100 (mild difficulty); 31-70 (marked difficulty) and 1-30 (severe difficulty).

The GAF is a 100-point tool rating overall psychological, social and occupational functioning of adults. The higher score range (91-100) refers to a superior functioning in a wide range of activities, and absence of symptoms. The lower score range (1-10) refers to persistent danger of severely hurting self or others; or persistent inability to maintain minimum personal hygiene; or serious suicidal act with clear expectation of death.

The CGI-S rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants".

The SF-36 is a health status survey with 36 questions measuring 8 dimensions (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health) that are subsequently aggregated into 2 summary scales, Physical Component Summary (PCS) and Mental Component Summary (MCS). Each item is scored into on a 0-100 range so that the lowest and highest possible scores are set at 0 and 100, respectively. All items are scored so that a high score defines a more favorable health state.

Participants assessed their satisfaction with paliperidone ER on a 5-point scale (very good, good, moderate, poor or very poor).

The Sleep Quality and Daytime Drowsiness evaluation scale is a self-administered scale that rates quality of sleep and daytime drowsiness. Participants indicated on a 5 point scale how well they have slept in the previous 7 days, score ranging from 1 (very badly) to 5 (very well) and how often they have felt drowsy within the previous 7 days, score ranging from 1 (not at all) to 5 (all the time).

The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia. The symptoms are rated on a 7-point scale from 1 (absent) to 7 (extreme psychopathology). Marder PANSS subscales include positive symptoms subscale consisting of 8 items with total score range of 8-56; negative symptoms subscale and disorganized thoughts subscale, each consisting of 7 items with total score range of 7-49; and uncontrolled hostility/excitement (UH/E) subscale and anxiety/depression subscale, each consisting of 4 items with total score range of 4-28. Higher score indicates greater severity.

ITT population included all participants who received at least 1 dose of study drug and had at least one post-baseline assessment. Missing data was imputed using LOCF. Here, 'n' signifies those participants who were evaluable for this outcome measure at specified time point.
