Background: 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.
Method: 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.
Results: 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).
Conclusion: 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.
