Two-Dimensional Self-Esteem: Adaptation of the Self-Liking/Self-Competence Scale into Turkish: A Validity and Reliability Study

Abstract

The objective of this study is to adapt the Self-Liking/Self-Competence Scale developed by Tafarodi and Swan (2001) into Turkish and to investigate its psychometric properties in a sampling made up of university students. A total of 604 students from Sakarya University and Hacettepe University participated in the research. The psychometric properties of the scale were analyzed by means of item analysis, internal consistency, test-retest, confirmatory factor analysis (CFA) and criterion-related validity methods. As a result of the CFA, the two-factor structure of the scale was confirmed as in its original form. The Cronbach's alpha coefficient was found to be .83 for the "self-liking" and .74 for the "self-competence". On the other hand, the test-retest reliability coefficient was found to be .72 for both factors. The findings obtained showed that the Self-Liking/Self-Competence Scale had sufficient levels of validity and reliability in the measurement of self-esteem.
