Psychometric validation of the Persian version of the community assessment of psychotic experiences-42 (CAPE-42) in Iranian college students

BackgroundPsychotic-like experiences are common in the non-clinical population, but the fact that they are often neglected can lead to even more serious problems. The present study assessed the psychometric validation of the Persian version of the Community Assessment of Psychotic Experiences (CAPE-42).Methods909 Iranian individuals participated in the study, completing the CAPE-42, as the confirmatory factor analysis was applied to assess the validity of the scale construct. The Pearson correlation coefficient Scale validity was estimated based on self-report measures for depression as well as positive and negative symptoms.ResultsThe result of the Confirmatory factor analysis demonstrated the relevance of the fitness of the current model with the three subscales (RMSEA =.077, SRMR =.09, CFI =.95, NFI =.94, PNFI =.9, IFI = 95, RFI =.94). Cronbach’s alpha for total score was 0.93, and for positive, negative, and depressive factors stood at 0.91, 0.71, and 0.88, respectively. There was a significant correlation among CAPE-42 25 scores and components of the Peters ?40 Delusions Inventory (PDI-40) and DASS-21.DiscussionThe Community Assessment of Psychotic Experiences scale was useful in assessing the psychotic experience in the non-clinical population especially Iranian non-clinical population, who were the subject of the research.
