Acceptability, engagement, and efficacy of cognitive remediation for cognitive outcomes in young adults with first-episode psychosis and social anxiety: A randomized-controlled trial

This is the authors' abstract. We don't add key points for this paper.

• Cognitive remediation leads to significant improvements in executive functions. • Cognitive remediation leads to significant improvements in visual memory. • Engagement in group cognitive remediation remains a challenge in this population. • Perceived competency and enjoyment influences engagement in cognitive remediation. Social anxiety disorder (SAD) is a frequent comorbidity in first-episode psychosis (FEP) and may increase cognitive impairments. Cognitive remediation (CR) is an effective treatment for cognition, particularly in a group format. This study aims to assess the efficacy, acceptability and engagement of group CR on cognitive outcomes in FEP+SAD compared to group cognitive-behavioral therapy (CBT). Participants with FEP+SAD were randomized to group CR ( n = 45) or CBT-SAD ( n = 51). They were assessed for cognition at baseline, post-therapy and 3- and 6-month follow-up. The CR group additionally completed scale to assess perceived competency and enjoyment in CR. Linear mixed models for repeated measures were used for cognitive scores. Descriptive statistics and t -tests were used to summarize acceptability, perceived competency, and enjoyment, for CR completers and non-completers. The CR group performed significantly better than CBT on executive functions and visual memory at post-therapy compared to baseline. Twenty participants completed CR (44 %; mean 5.5 sessions). At week 1, CR non-completers presented higher levels of perceived competency. Completers reported higher enjoyment scores at the last session compared to the first session. Group CR is effective for cognitive outcomes in FEP+SAD, but acceptability and engagement present a challenge. Future studies are necessary to explore approaches promoting engagement.
