59. Social Functioning, Sleep Quality, and Psychotic-Like Experiences: Towards an Additive Prediction Model

Impairments in social and role functioning have been associated with the prodromal phase of psychosis. Additionally, sleep disturbances impacting daily functioning have been detected across the schizophrenia spectrum. Relationships between social functioning, sleep quality, and psychotic-like experiences (PLEs) in non-help seeking populations are less understood. The current project aimed to investigate whether sleep quality moderated the relationship between social functioning and PLEs in a community sample of 3,061 non-help seeking participants between the ages of 18-35. Participants completed the Social Functioning Scale (SFS), Pittsburgh Sleep Quality Index (PSQI), and the Prodromal Questionnaire (PQ). PQ-positive items were used to index PLEs. Bivariate correlations revealed significant associations between social functioning, sleep, and PLEs. As expected, poor sleep and poor social functioning were associated with increased endorsement of PLEs. Contrary to expectation, poor sleep quality was associated with better social functioning. A moderation analysis was conducted using Hayes’ PROCESS macro, but results did not support the hypothesized moderation effect. However, results from multiple regression analyses indicated that both poorer sleep and poorer social functioning were significantly associated with PLEs when included in the same model. These findings suggest that sleep disruptions and poorer social functioning act additively to influence PLEs and are both important predictors of psychotic symptoms. Due to deleterious effects of poor sleep on physical and emotional health, these findings provide impetus to further investigate relationships between sleep quality, social functioning, and PLEs in non-help seeking samples using actigraphy, mobile sensing, and EMA techniques.
