Neurocognitive and social cognitive training for youth at clinical high risk (CHR) for psychosis: A randomized controlled feasibility trial

Cognitive deficits are present in individuals at clinical high risk for psychosis (CHRP). We developed Cognition for Learning and for Understanding Everyday Social Situations (CLUES), an integrated social- and neurocognitive remediation intervention for CHRP, and examined its feasibility and efficacy compared to an active control intervention in a pilot randomized controlled trial. Thirty-eight individuals at CHR-P were randomized to CLUES or Enriched Acceptance and Commitment Therapy (EnACT). Participants were assessed at baseline, end of treatment and 3-month follow-up for changes in social/role functioning, neuro- and social cognition, and symptoms. Social functioning significantly improved for participants in CLUES over EnACT, at end of treatment and 3-month follow-up. CLUES participants also showed greater improvements in social cognition (theory of mind and managing emotions). The results support feasibility of CLUES and suggest preliminary efficacy. Future randomized controlled trials of CLUES in a larger sample, with additional treatment sites, could help determine efficacy of CLUES, and investigate whether CLUES can be effectively implemented in other settings.
