Reliability and Validity of Five-Level Response Continua for the Career Decision Self-Efficacy Scale

Abstract

The present study, based on three samples of college students totaling 1,832 participants, resulted in the conclusion that a 5-level response continuum for the short form of the Career Decision Self-Efficacy Scale (CDSE)1 proved at least as reliable and valid as the 10-level continua used in normative studies. Values of coefficient alpha ranged from .78 to .87 for the 5-level continuum, in contrast to .69 to .83 for the 10-level continuum. Criterion-related validity correlations with career indecision and vocational identity were comparable for the two response continua. Validity with respect to the scales of the Career Decision Profile was examined, as was construct validity with respect to measures of hope, goal stability, and positive and negative affect. Overall, the study suggests the psychometric quality of the CDSE when 5-level response continua are used and adds to knowledge of the nomological network of the construct.1
