Abstract

OBJECTIVES
The purpose of this study was to develop a Korean Strength Scale for Youth and to examine its validity and reliability.
METHODS
The Korean Strength Scale for Youth is based on a self-reporting, 100 item questionnaire that measures 25 strengths. Each scale item was given a 0-5 rating on a 6-point scale. In order to test the scale's validity and reliability, data were collected from 422 youths (aged 12-18 years). The strength measures included in our analyses were those contained within the Korean Strength Scale for Youth, the Positive Affect and Negative Affect Schedule, the Korean Well-Being Scale for Adolescents, and the Short Five Factor Personality Scale for Children.
RESULTS
The results of exploratory factor analysis of the Korean Strength Scale for Youth scale-measures indicated the importance of four factors. The Korean Strength Scale for Youth was shown to have acceptable psychometric properties, including good internal consistency, test-retest reliability, and high convergent correlations.
CONCLUSION
The Korean Strength Scale for Youth is a reliable and valid instrument that can be used to assess strengths in adolescents.
