创伤后应激障碍症状对单亲家庭大学生睡眠质量的影响:精神病性体验的中介作用OA

Objective:To explore the relationship between posttraumatic stress disorder(PTSD)symptoms and sleep quality and the mediating effect of psychotic-like experiences in college students from single parent families.Methods:From March to April 2023,1465 single family college students were investigated using the posttraumatic Stress Disorder Checklist-Civilian version(PCL-C),Pittsburgh Sleep Quality Index(PSQI)and Community Psy-chiatric Experience Assessment Scale(CAPE-P15)by convenience sampling method.Results:The positive detection rates of posttraumatic stress disorder,sleep quality and psychotic-like experiences were 19.7％,19.9％and 11.9％,respectively.10.58％of college students from single-parent families had PTSD symptoms to some extent,and 9.15％of college students from single-parent families had obvious PTSD symptoms.There was no significant difference in PLEs,sleep quality and PTSD between dissociated and widowed college students.The PTSD was posi-tively correlated with sleep quality,PLEs and its dimensions(P＜0.01).PTSD positively predicted psychotic-like experiences(β=0.52,P＜0.001)and sleep quality(β=0.49,P＜0.001),and psychotic-like experiences positively predicted sleep quality(β=0.14,P＜0.001).The total score of psychotic-like experiences and its sub-dimensions(persecution perception,strange experience and perceptual abnormality)had significant partial mediating effects on PTSD and sleep quality of college students from single-parent families,and the mediating effects accounted for 13.01％,11.61％,9.78％and 2.76％of the total effects,respectively.Conclusion:College students from single-par-ent families often face more psychological challenges.In college students from single-parent families,PTSD symp-toms and PLEs can significantly positively predict sleep quality.PTSD symptoms can predict sleep quality directly,and can also predict sleep quality through the mediating role of PLEs.
