Objective:To explore the prevalence of adolescent psychotic-like experiences(PLEs)and compared the psychological network features between PLEs-positive and PLEs-negative groups,focusing on the associations and centralities of strengths and difficulties,positive mental health,resilience,and sleep quality.Methods:A cluster sampling survey was conducted among 15,574 students from six secondary schools in Luzhou,Sichuan Province,China,between January and April 2025,utilizing the Luzhou Social Mental Health Management Platform.Partici-pants were screened for psychotic—like experiences(PLEs)using the Chinese version of the 16-item Prodromal Questionnaire(CPQ-16).Psychological status and sleep quality were assessed using the Strengths and Difficulties Questionnaire(SDQ),the Warwick-Edinburgh Mental Wellbeing Scale(WEMWBS),the 10-item Conner-David-son Resilience Scale(CD-RISC-10),and the Pittsburgh Sleep Quality Index(PSQI).Network structure estimation and analysis were performed using R,and bootstrap methods were applied to examine the accuracy and stability of the network.Results:The prevalence of positive psychotic-like experiences(PLEs)among adolescents was 15.82％.Compared to the PLEs-negative group,the PLEs-positive group scored significantly higher on the total SDQ diffi-culties score(t=-68.014,P＜0.01)and across all its subscales,but obtained significantly lower scores on the WEM-WBS and the CD-RISC-10(t=42.264,36.613;P＜0.01).PLEs showed moderately strong positive correlations with emotional symptoms,sleep quality,and the total SDQ difficulties score(r=0.587～-0.590,P＜0.01),and sig-nificant negative correlations with CD-RISC-10 and WEMWBS scores(r=-0.356～-0.391,P＜0.01).Network a-nalysis revealed a denser network in the PLEs-positive group(35 edges,density=0.777),with the PSQI node ex-hibiting the highest strength centrality,betweenness centrality,and expected influence.In the PLEs-negative group,both the PSQI and SDQ-difficulties nodes showed prominent betweenness centrality.Edge weight analysis further indicated that in the PLEs-negative network,the strongest positive edges were between PSQI and SDQ-difficul-ties,SDQ-prosocial and SDQ-peer problems,and WEMWBS and PSQI,while the strongest negative edge was be-tween WEMWBS and SDQ-emotional symptoms.In the PLEs-positive network,the strongest positive edges were between PSQI and SDQ-difficulties and between SDQ-prosocial and SDQ-peer problems,whereas the strongest negative edge was between SDQ-peer problems and SDQ-difficulties.Conclusion:Adolescents with positive psy-chotic—like experiences(PLEs)are associated with elevated psychobehavioral difficulties,poorer sleep quality,and reduce psychological resilience and mental well-being.Sleep problems may serve as a pivotal component within the psychopathological network of these affected youths.
