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 undergraduate-level student populations are less understood. The current project aimed to investigate whether self-reported measures of sleep quality would moderate the relationship between social functioning and PLE endorsement in a community sample of 3042 undergraduate student participants between the ages of 18–35. Participants completed the Social Functioning Scale, the Pittsburgh Sleep Quality Index, and the Prodromal Questionnaire, which indexed 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. In hierarchical multiple regression models, the interaction between social functioning and sleep was not associated with PLE endorsement. Results indicated that both poor sleep and poor social functioning were significantly associated with PLEs when included in the same model. These findings suggest that poor social functioning and disrupted sleep may act additively to influence PLEs, and that they are both important contributors to 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 using such high-resolution methods as actigraphy, mobile sensing, ecological momentary assessment, and neuroimaging.

社会和角色功能的损害与精神病的前驱期有关。此外，已在精神分裂症谱系中检测到影响日常功能的睡眠障碍。本科生群体的社会功能、睡眠质量和精神病样体验 (PLE) 之间的关系鲜为人知。目前的项目旨在调查自我报告的睡眠质量测量是否会在 18-35 岁的 3042 名本科生参与者的社区样本中调节社会功能和 PLE 认可之间的关系。参与者完成了社会功能量表、匹兹堡睡眠质量指数和对 PLE 进行索引的前驱问卷。双变量相关性揭示了社会功能、睡眠和 PLE 之间的显着关联。正如预期的那样，睡眠不足和社交功能不佳与对 PLE 的认可增加有关。与预期相反，睡眠质量差与更好的社会功能有关。在分层多元回归模型中，社会功能和睡眠之间的相互作用与 PLE 认可无关。结果表明，当包含在同一模型中时，睡眠质量差和社交功能差都与 PLE 显着相关。这些发现表明，不良的社会功能和睡眠中断可能会叠加影响 PLE，并且它们都是精神病症状的重要贡献者。由于睡眠不足对身体和情绪健康的有害影响，
