Measure Description |
Time Frame |
|---|---|---|
|
The percentage of patients with a 30% reduction from baseline in Positive and Negative Syndrome Scale (PANSS)
Time Frame: Baseline, Week 13
|
The PANSS is a 30-item scale (range 30-210) designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control.
The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology).
The PANSS total score consists of the sum of all 30 PANSS items.
Higher scores indicate worsening.

The change from baseline in Positive and Negative Syndrome Scale (PANSS) score
Time Frame: Baseline, Week 13
|
The PANSS is a 30-item scale (range 30-210) designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control.
The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology).
The PANSS total score consists of the sum of all 30 PANSS items.
Higher scores indicate worsening.
|
Baseline, Week 13
|
|
The change from baseline in Clinical Global Impression - Severity (CGI-S)
Time Frame: Baseline, Week 13
|
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 patient.
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 patients".
Higher scores indicate worsening.
|
Baseline, Week 13
|
|
The change from baseline in Medication Satisfaction Questionnaire (MSQ)
Time Frame: Baseline, Week 13
|
The MSQ is a 7-point, Likert-type scale rated as follows: 1=Extremely Dissatisfied, 2=Very Dissatisfied, 3=Somewhat Dissatisfied, 4=Neither Satisfied or Dissatisfied, 5=Somewhat Satisfied, 6=Very Satisfied, 7=Extremely Satisfied.
Worst value is 1 (Extremely Dissatisfied) and best value is 7 (Extremely Satisfied).
|
Baseline, Week 13
|
|
The change from baseline in Involvement Evaluation Questionnaire (IEQ)
Time Frame: Baseline, Week 13
|
The IEQ is a 31-item questionnaire that assesses the encouragement and care that the caregiver has to give to the patient, to personal problems between patient and caregiver, and to the caregiver's worries, coping and subjective burden.
All items are scored on 5-point Likert scales (never, sometimes, regularly, often, always).
|
Baseline, Week 13
|
|
The change from baseline in Medication Adherence Rating Scale (MARS)
Time Frame: Baseline, Week 13
|
The MARS is a ten-item yes/no self-report measure of medication adherence in psychosis.
Total scores range from 0 (low likelihood of medication adherence) to 10 (high likelihood of medication adherence).
|
Baseline, Week 13
|
|
The change from baseline in Medication Preference Questionnaire (MPQ)
Time Frame: Baseline, Week 13
|
The MPQ is used to investigate which treatment (oral or injection) the patients prefer and why they prefer this treatment, and to investigate which injectable site (deltoid or gluteal) they prefer and why they prefer this treatment.
