Efficacy Study of Paliperidone to Evaluate Subjective Change in Well-being and Drug Attitude in Schizophrenic Participants

The DAI-10 is a 10-item questionnaire to assess 1) subjective experience of drug and 2) attitudes and beliefs toward neuroleptics which may influence compliance in schizophrenia participants. It is the binary scale assessing the participant's subjective response. A 'compliant' response is scored as +1; a dysphoric response is scored as -1. A positive sum of items indicates a positive subjective response (SR); a negative sum of scores indicates a negative SR (non-compliant). The final score is the grand total of the positive and negative points. Total score ranges from (-) 10 to (+) 10, higher score indicates positive SR (compliant) and lower score indicates negative SR (non-compliant). Change from Baseline was calculated as value at Baseline minus value at Week 24. Data for three groups is presented here, based on participants' transition to Paliperidone ER from other oral antipsychotics.

Time frame: Baseline and Week 24

Population: The ITT population for efficacy included all the participants who received paliperidone ER at least once and who had at least 1 post baseline efficacy assessment.

The SWN-20 scale is a 20 item scale that was originally designed to explore the subjective experience of psychotic participants. The SWN scale contains five sub-scales consisting of four items each: mental functioning (MF), self-control (SC), emotional regulation (ER), and social integration (SI), physical functioning (PF). The total score ranges from a minimum of 20 (poor subjective experience) to a maximum of 120 (excellent subjective experience). SWN scores appear to correlate with measure of objective psychopathology, quality of life and other self-ratings of mood. Emotional Regulation subscale score ranges from 0 to 24 and higher score indicates improvement of disease. Change from Baseline was calculated as value at Baseline minus value at Week 24. Data for three groups is presented here, based on participants' transition to Paliperidone ER from other oral antipsychotics.

Daytime drowsiness was assessed by an 11-point visual analog scale that rates how well participants slept. Participants indicated on the scale (from 0 to 100 millimeter) how often they felt drowsy in the previous 7 days (from 0: very badly to 100: very well). Change from Baseline was calculated as value at Baseline minus value at Week 24. Data for three groups is presented here, based on participants' transition to Paliperidone ER from other oral antipsychotics.

Higher score indicates worsening of disease. Change from Baseline was calculated as value at Baseline minus value at Week 24.

The SCL90-R (Derogatis, 1992) measures 9 domains, including somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism, which provides a global index of distress, the Global Severity Index (GSI). SCL-90-R includes 90 items rated on 5-point scale, ranging from 0 (not at all) to 4 (extremely). Total scale score range from 0 to 360. Higher scores indicate worsening of disease. Change from Baseline was calculated as value at Baseline minus value at Week 24. Data for three groups is presented here, based on participants' transition to Paliperidone ER from other oral antipsychotics.

Time frame: Baseline and Week 24

Population: The ITT population for efficacy included all the participants who received paliperidone ER at least once and who had at least 1 post baseline efficacy assessment. N (number of participants analyzed) signifies the participants evaluable for this measure.

The PSP scale assesses the degree of dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care and disturbing and aggressive behavior. The score ranges from 1 to 100, divided into 10 equal intervals to rate the degree of difficulty (1, absent to 6, very severe) in each of the 4 domains. Participants with a score of 71 to 100 have a mild degree of difficulty; from 31 to 70, varying degrees of disability; less or equal to 30, functioning so poorly as to require intensive supervision. Change from Baseline was calculated as value at Baseline minus value at Week 24. Data for three groups is presented here, based on participants' transition to Paliperidone ER from other oral antipsychotics.
