Abstract

This study aims to develop a short form of the Peer Rejection Sensitivity Questionnaire (PRSQ; Choi, 2023) and assess its psychometric properties. A sample of 463 children in the 5th and 6th grades from elementary schools participated in the study. Self-report data were collected using questionnaires on peer rejection sensitivity, in-secure friendship attachment, and peer relationship problems. Exploratory factor analyses yielded a short form of the PRSQ consisting of 17 items with four factors including re-jection expectation, anger/depression, interpretation bias, and anxiety/withdrawal. Correlation analyses demonstrated strong associations between scores of the original and the short forms. The short form of the PRSQ exhibited high internal consistency and split-half reliability. Furthermore, it displayed appropriate criterion-related validity, with substantial associations with the CRSQ. Children in the top 30 percent of insecure friend-ship attachment and peer relationship problems scored significantly and practically higher on peer rejection sensitivity than those in the bottom 30%, supporting the known-group validity of the short form. The short form of the PRSQ serves as a valuable instrument for measuring peer rejection sensitivity of school-age children within research and counsel-ing settings.
