Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Percentage of Participants Achieving Symptomatic Remission by Means of Positive and Negative Syndrome Scale (PANSS)
Prazo: End of study (Up to Week 12)
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. 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.
End of study (Up to Week 12)
Percentage of Participants Achieving Improvement in Personal and Social Performance (PSP) Score by at Least One Category on PSP Scale
Prazo: End of study (Up to Week 12)
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). Percentage of participants achieving improvement in PSP score by at least one category was reported.
End of study (Up to Week 12)
