Psychometric Properties of Post Event Processing Questionnaire in student population

Post-event processing involves rumination about perceived inadequacy in a past social situation and has been proposed as an important maintaining factor in social phobia.
Aims: This paper investigated the psychometric properties of Post Event Processing Questionnaire (PEPQ) in a student sample.
Participants were 460 people (280 female, 180 male) who answered the PEPQ, and 284 of the subjects (198 female and 86 male) completed four Social anxiety related questionnaires including SPAI, SAFE, LSAS-SR and SPS in addition to PEPQ. Also, fifty-five Social Phobic patients answered the PEPQ. The Pearson correlation, Independent sample t-test, Cronbach Alpha and Confirmatory Factor Analysis (CFA) is used as the data analysis method.
The Pearson correlation between the PEPQ and the Criteria Scales and between the test and re-test PEPQ score was significant. The CFA replicated the one factor solution for the PEPQ. The Independent sample t-test showed significant difference in PEPQ score between social anxiety group and control group. Also, internal consistency of the PEPQ was acceptable. Comparing with people with self-perspective, participants with observer perspective had a higher score in PEPQ, state anxiety, SPAI, LSAS-SR, SAFE and SPS.
Thereupon, it seems the PEPQ is a reliable instrument for assessment of the Post Event processing in Iranian population.
