Outcome Measures

Primary Outcomes (1)

  • Change from Baseline in Total Personal and Social Performance (PSP) Score at Month 12

    The PSP is a clinician-rated scale that reflects social functioning in 4 domains of behavior (socially useful activities including work and study, personal and social relationships, self care, and disturbing and aggressive behaviors). The total score ranges from 1 to 100 (score of 71 to 100 will have a mild degree of difficulty; from 31 to 70, varying degrees of disability; less than or equal to 30, functioning so poorly as to require intensive supervision) divided into 10 equal intervals to rate the degree of difficulty (i=absent to vi=very severe) in each of the 4 domains.

    Baseline and Month 12

Secondary Outcomes (4)

  • Change from Baseline in Global Assessment of Functioning (GAF) Score at Month 12
