Abstract

Objectives: The Child Report of Post-traumatic Symptoms (CROPS) and the Parent Report of Post-traumatic Symptoms (PROPS) are screening measures for post-traumatic symptoms in children. The present study aimed to investigate the reliability and validity of the Korean versions of the CROPS and the PROPS. Methods: The Korean versions of the CROPS and the PROPS were administered to a sample of 304 children aged 6 to 15 years old. The internal reliability, test-retest reliability, factorial validity, predictive validity and concurrent validity were evaluated. Results: The reliability of the CROPS and the PROPS was shown to have excellent internal consistency and test-retest correlation. The single factor structure of the PROPS was good and that of the CROPS was borderline acceptable according to confirmatory factor analysis. Other validity measures such as the predictive validity and concurrent validity were also shown to be satisfactory. Conclusion: This study demonstrated that the Korean versions of the CROPS and the PROPS were reliable measures with satisfactory psychometric qualities. Because it takes less than 5 minutes to fill out the CROPS and the PROPS, respectively they can be quick and easy screening scales for assessing post-traumatic symptoms in Korean children.
