Cross-Cultural Validation of the Short Form of the Life Skills Scale for Adolescents and Adults in Adolescents in Four Countries

Abstract

This study aimed to translate the Japanese version of the Life Skills Scale for Adolescents and Adults (LSSAA) into Chinese, English, and Korean, simplify it, and assess its reliability and validity. Validation was performed using individual data of 9941 high-school students from China, Japan, Korea, and the United States collected by the 2021 “Survey on Experiences and Attitudes Related to the Corona Crisis” conducted by the National Institution For Youth Education. Confirmatory factor analysis showed that the four-factor model of the LSSAA fit the data for all four countries. Testing of the measurement invariance of the four-factor model among the four countries supported the adoption of a weak invariance model, and the LSSAA scores were comparable across all four countries. These results suggest that the LSSAA has good reliability and validity and applies to adolescents in English-speaking countries and some Asian counties.
