Primary Outcome Measures

Name	Time	Method
Conversion of psychosis	12-month post-intervention	Proportion of subject that convert from at-risk state to psychosis
Functioning: Measured by Role Functioning Scale (RFS)	Changes from baseline to immediate, 6- and 12-month post-intervention	Measured by Role Functioning Scale (RFS). The RFS is comprised of four single rating scaled for evaluating the functioning of individuals in specified areas of everyday life. The four role functions assessed are:(1)Working: productivity, (2) Independent living and self care, (3) Immediate social network relationships, and (4) Extended social network relationship. The values on each of the four scales range from 1 (minimal level of role functioning), to 7 (hypothetically optimal level of role functioning). Each of the seven points on the scales is accompanied by a behaviorally defined description.
Functioning: Measured by Social and Occupational Functioning Assessment Scale (SOFAS)	Changes from baseline to immediate, 6- and 12-month post-intervention	Measured by Social and Occupational Functioning Assessment Scale (SOFAS). The SOFAS is an observer rating scale. Ratings should be based on subject's behavior during the last 1 month. The score ranges from 0-100. A higher score represents a better outcome.

Secondary Outcome Measures

Name	Time	Method
Social anxiety :Measured by Liebowitz Social Anxiety Scale (LSAS)	Immediate, 6- and 12-month post-intervention	Measured by Liebowitz Social Anxiety Scale (LSAS). The LSAS consists of 24 questions, the rater has to rate from 0-3 in Fear or Anxiety domain or Avoidance domain for each of the 24 questions. The higher score represents more severe social anxiety.

Positive psychotic symptoms	Immediate, 6- and 12-month post-intervention	Measurement of positive symptoms using the Chinese version of the Psychotic Symptom Rating Scales (C-PSYRATS). It comprises of the auditory hallucinations (AHS) and delusions subscales (DS). The AHS has 11 questions and the DS consists of 6 questions, each question has the responses ranging from 0-4. The higher score represents more severe positive psychotic symptoms.
