Primary Outcome Measures
NameTimeMethod
changes in personal and social performance (PSP) scores at week 2626 weeks

PSP consists of four main areas: 1. Socially useful activities (e.g., housework, voluntary work) including work and study; 2. Personal and social relationships (i.e., partner, family relationships, friends); 3. Self-care (i.e., personal hygiene, care of one's appearance); 4. Disturbing and aggressive behavior. The maximum scores is 100, the minimum scores is 1, higher values represent a better outcome

Secondary Outcome Measures
NameTimeMethod
changes in MATRICS Consensus Cognitive Battery (MCCB) domain scores at week 26 in treatment group26 weeks

MATRICS Consensus Cognitive Battery (MCCB) includes 10 tests that measure seven cognitive domains: speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving and social cognition. Scores for the individual tests will be calculated according to the developer's recommended scoring algorithms

changes in Paced Auditory Serial Addition Task (PASAT) test at week 26 in treatment group26 weeks

PASAT is a neuropsychological test used to assess capacity and rate of information processing and sustained and divided attention

changes in PANSS five-factor model scores at week 26 in treatment group26 weeks

five-factor model is another model of PANSS. It is a medical scale used for measuring symptom severity of patients with schizophrenia. the maximum scores is 210, the minimum scores is 30. the higher values represent a worse outcome. the total scores are the sum of subscales.

changes in MCCB at every visit in treatment group during 26 weeksbaseline, week 8, week 26

MATRICS Consensus Cognitive Battery (MCCB) includes 10 tests that measure seven cognitive domains: speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving and social cognition. Scores for the individual tests will be calculated according to the developer's recommended scoring algorithms

changes in Groove Pegboard Test (GPT) at week 26 in treatment group26 weeks

GPT is a test used to assess fine motor skills and speed. this test measure the time it takes to put 25 nails in the pegborad in a defined order

changes in PSP at every visit in treatment group during 26 weeksbaseline, week 8, week 26

PSP consists of four main areas: 1. Socially useful activities (e.g., housework, voluntary work) including work and study; 2. Personal and social relationships (i.e., partner, family relationships, friends); 3. Self-care (i.e., personal hygiene, care of one's appearance); 4. Disturbing and aggressive behavior. The maximum scores is 100, the minimum scores is 1, higher values represent a better outcome

changes in positive and negative syndrome scale (PANSS) total scores at week 26 in treatment group26 weeks

PANSS is a medical scale used for measuring symptom severity of patients with schizophrenia. the maximum scores is 210, the minimum scores is 30. the higher values represent a worse outcome. the total scores are the sum of subscales.
