Abstract (Summary)

When adolescents deemed at Clinical High Risk (CHR) for developing psychosis are left untreated, significant observable improvements rarely occur. But does an early intervention program designed for them increase global functioning and decrease positive symptoms? Archival data were examined for 72 adolescents and young adults between the ages of 12 and 25 who were enrolled at First Hope of Contra Costa County (California, USA, 01/01/2014 to 12/31/2017), a program designed to emulate the Portland Identification and Early Referral (PIER) program model. The following assessment data from the Structured Interview for Psychosis-Risk Syndromes (SIPS assessment) were collected at intake and one year in the program: (1) Global Assessment of Functioning (GAF-M) scores (n=72); and (2) five Scales of Psychosis-Risk Symptoms (SOPS) scales of positive symptoms (n=45, including P.1 (unusual thought content), P.2 (suspiciousness/persecutory ideas), P.3 (grandiose ideas,) P.4 (perceptual abnormalities/hallucinations), P.5 (disorganized communication). As hypothesized, participants after one year showed significant increases in global functioning (GAF-M scores), and significant decreases in positive symptoms (Total SOPS scores, and scores on all SOPS P scales). The present study provides non-experimental evidence based on trained clinicians’ impressions using well-developed assessment tools to support the efficacy of programs like First Hope, and the Portland Identification and Early Referral (PIER) treatment program model.
