Psychometric properties of Chinese version of post-event processing inventory trait in high school students / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To Chinesize Post-Event Processing Inventory Trait (PEPI-T) and verify the reliability and validity of its application in high school students.Methods:First, the PEPI-T was translated and pre-measured, then the wording according to the pre-measurement results was adjusted and back-translated.Then, the Chinese version of PEPI-T(PEPI-T-C) was finalized.In total, 947 adolescents aged from 15 to 19 were recruited to complete Social Anxiety Scale for Adolescents, Short Mood and Feelings Questionnaire, General Self-Efficacy Scale and PEPI-T-C, which were used as validity indicator.Results:Confirmatory factor analysis results showed that the PEPI-T-C still followed the three dimentions of self-judgement, frequency and intensity of the original scale and showed good model fit indices (χ 2/ df=2.59, RMSEA=0.04, CFI=0.97, TLI=0.95, SRMR=0.03). The internal consistency coefficients for PEPI-T-C was 0.78, while the three subscales was (0.44-0.75). PEPI-T-C and its subscales were significantly correlated with social anxiety and depression ( r=0.22-0.43, all P<0.01). The subscale of intensity showed significant correlation with self-efficacy( r=-0.11, P<0.01). PEPI-T-C and its subscale of self-judgement and frequency showed no significant correlations with self-efficacy( P>0.05). Conclusions:PEPI-T-C showed an acceptable reliabilities and validities in Chinese high school students, and would be used to assess their post-event rumination.Future research should examine the psychometric properties of PEPI-T-C in other Chinese adolescents’ samples.
