Epidemiology of psychotic-like experiences by subtypes and their relationship with emotional regulation and affective lability among Chinese college students.

Although psychotic-like experiences (PLEs) are transient and not pathognomonic for psychiatric disorders, they may increase the risk of concurrent and future psychiatric disorders. However, the prevalence of PLEs and the different effects of PLE subtypes on mood outcomes are still unclear. Thus, this study seeks to investigate the prevalence of PLE subtypes and explore their relationship with the use of specific emotion regulation strategies and the level of affective lability among college students. The history of PLEs, the level of affective lability, and the use of specific emotion regulation strategies were assessed via self-reported questionnaires, and 1905 college students and 1812 college students were included in separate analyses. This study found that 14.44% of college students reported ever experiencing any of the five PLEs, with males reporting more PLE symptoms and a higher number of PLEs than females. Different PLE subtypes had different effects on the use of specific emotion regulation strategies (cognitive reappraisal or suppression) and the level of affective lability and also showed gender differences. Cognitive reappraisal and suppression differently predicted affective lability in males and females, and cognitive reappraisal mediated the relationship between hearing voices in PLEs and affective lability in males. In conclusion, PLEs were common in Chinese college students and gender differences were revealed in the prevalence of PLE subtypes. PLEs were associated with the use of specific emotion regulation strategies and the level of affective lability. Cognitive reappraisal may be a promising target for intervention aimed at relieving the effect of PLEs in non-clinical individuals.
