Construction and Psychometric Properties of a Short Form of the Personal Experiences Checklist.

Abstract

Peer victimization is a significant problem concerning young people. However, there are few brief measures that cover the key domains of victimization, including cyber victimization. Therefore, the objective of the present study was to construct and validate a short form version of the Personal Experiences Checklist (PECK) to be able to measure victimization efficiently and effectively. The PECK was originally developed to measure a young person's experience of victimization and provides scores for four subscales (relational-verbal, cyber, physical, and victimization in relation to culture) as well as a total score. A sample of N = 1,040 school students from Grades 4 to 9 (mean age = 12.2 years) derived from two studies was used to construct and cross-validate the structure of a Personal Experiences Checklist Short Form (PECK-SF) using confirmatory factor analysis and item response theory analysis. Based on discriminative ability and consideration of item content, 14 items were selected to form the PECK-SF, which demonstrated good internal consistency (Cronbach's α = .83). Given the small number of items, the use of subscales is not advised. However the PECK-SF total scale represents a potential alternative to the long form of the PECK and provides a brief and general index of victimization.
