Outcome Measures

Primary Outcomes (3)

  • Functioning: Measured by Social and Occupational Functioning Assessment Scale (SOFAS)

    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.

    Changes from baseline to immediate, 6- and 12-month post-intervention

  • Functioning: Measured by Role Functioning Scale (RFS)

    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.

    Changes from baseline to immediate, 6- and 12-month post-intervention

  • Conversion of psychosis

    Proportion of subject that convert from at-risk state to psychosis
