摘要

Background

Despite evidence linking psychotic-like experiences (PLEs) and social functioning deficits in youth at the risk of transitioning to psychosis, this association remains poorly understood. To address this, we explored the association between components of social performance and PLEs in adolescents aged 13–18 using a novel virtual reality (VR) paradigm for real-time assessment.

Methods

Adolescents (N = 146) aged 13–18 were recruited as part of a larger cohort study conducted by the same research group (YVORI_PRO) and invited to participate via the following criteria: those reporting highly indicative positive PLEs (HIP, N = 88) and those reporting no or less indicative PLEs (no-HIP, N = 58). Self-report, behavioural and physiological components of social performance were collected using a portable VR headset and a medical wristband. Participants entered a virtual recreational area with three levels of social ambiguity and were encouraged to interact with avatars. MANOVA was performed to check for overall group differences and repeated measures ANOVAs were conducted to examine the effects of group and level of ambiguity, as well as their interaction, on daily social performance.

Results

During virtual social interactions, adolescents with HIP reported higher levels of anxiety, fear of negative evaluation (FNE) and avoidance than the no-HIP group. No significant difference between groups was found for self-confidence. With increasing social ambiguity in VR, anxiety, FNE and avoidance increased in both groups, while self-confidence decreased. No significant group differences were found in behavioural or physiological components of social performance. Interpersonal distance and pulse rate increased significantly with increasing level of ambiguity, but pulse rate variability and skin conductance did not.

Conclusion

The results suggest that adolescents with HIP may present specific difficulties related to social performance, which may carry additional psychosis risk. The new VR social scenario appears to be an acceptable, safe and effective tool to measure social performance in adolescents experiencing PLEs.
