Changes in psychotic-like experiences and related influential factors in technical secondary school and college students during COVID-19

OBJECTIVE: Although students have been found to be at high risk of distress during the COVID-19 pandemic, little is known about the pandemic's impact on psychotic-like experiences (PLEs). We conducted a study in technical secondary school and college students before and during the pandemic to explore changes in PLEs and relevant influential factors. METHODS: A total of 938 students completed both waves of the survey through electronic questionnaires. PLEs were assessed using the 15-item Positive Subscale of the Community Assessment of Psychic Experiences (CAPE-P15). Childhood trauma, perceived stress, resilience, and demographic factors were evaluated at baseline, and psychological status was measured during the pandemic. RESULTS: The overall CAPE-P15 scores significantly decreased during the pandemic. Students with persistent PLEs showed the most severe COVID-19 related psychological symptoms, followed by new-onset and remitted individuals; those without PLEs exhibited the mildest symptoms (all p < .001). A single parent family (OR = 4.707), more childhood trauma (OR = 1.056), and a higher family income (OR = 1.658) were predictive of new-onset PLEs during the pandemic, while better resilience was a protective factor, associated with remission of previous PLEs (OR = 0.932). CONCLUSIONS: Despite a downward trend in the prevalence of PLEs during the pandemic, PLEs predict greater serious psychological impact due to COVID-19, especially for students with persistent PLEs. Interventions that cultivate students' resilience are urgently needed to reduce PLEs and improve mental health, especially for students from single parent households or those who have experienced childhood trauma.
