Core Self-Evaluations Scale: The Formation of a Construct

This study investigated reliability, validity and confirmatory factor structure of the Core Self-Evaluations Scale (CSES; Judge, Erez, Bono & Thoresen, 2003). Six hundred and twenty two students (198 males, 424 females) were selected using multi-stage sampling method. The participants completed the CSES, the Personal Views Survey (PVS; Hardiness Institute, 1985), the Rosenberg Self-Esteem Scale (1965), the Generalized Self-Efficacy Scale (GSES; Judge, Locke, Durham & Kluger,1998), the Internality, Powerful Others and Chance Scale (IPC; Levenson,1981), the Youth Coping Index (YCI; McCubbin, Thompson & Elver, 1996), the Neuroticism Scale of the Eysenck Personality Inventory (Eysenck & Eysenck, 1968),the Beck Depression Inventory-Short Form (BDI-SF; Beck & Beck, 1972). The factor structure of theCSESwas assessed by exploratory and confirmatory factor analysis.The results indicated that the CSES had a good internal consistency. The Cronbach α and 2-weeks test-retest reliability were .87 and .82, respectively. The positive correlation of the CSES with the Personal Views Survey, the Rosenberg Self-Esteem Scale, the Generalized Self-Efficacy Scale, the Internality, Powerful Others and Chance Scale, and the Youth Coping Index indicated the convergent validity of the CSES. The negative correlation of the CSES with the Neuroticism Scale and the Beck Depression Inventory indicated the divergent validity of the CSES. The factorial analyses indicated that the CSES Scale was unidimensional.The findings suggest that the Core Self-Evaluations Scale has a good psychometric properties in a sample of Iranian Students.
