Screening Performance of the Korean Version of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI GPSS)

Abstract

The CAGI GPSS is the only instrument that was specifically developed to measure adolescent problem gambling. The purpose of this study is to evaluate the screening performance of the Korean version of the CAGI GPSS. The Korean version of the CAGI GPSS was validated with 1456 adolescents in South Korea. The results indicated that the Korean version of the CAGI GPSS was a unidimensional instrument, like its English version, and that it showed satisfactory internal consistency reliability and convergent validity. The Korean version of the CAGI GPSS demonstrated optimal performances at a cut-off score of 5. The cut-off score of 5 found in this study should be used to identify adolescents in school settings who had gambling problems. However, the sensitivity and specificity results should be interpreted with caution, because the adolescents included in the reference group might not represent all adolescents with gambling problems. Further evaluation is needed to heighten the values of the Korean version of the CAGI GPSS.
