For comparison of one-, three-, and four-factor structures of the Indecision scale of the Career Decision Scale, results of confirmatory factor analysis (N = 686) indicated the best fit for the three-factor structure. Multiple regression analysis results indicated incremental validity of the five-factor model for predicting dimensions of career…

This article describes the development and revision of the Ethical Decision-Making Scale. Construct and content validity are reported. In addition, the results of a test-retest and a principal component factor analysis are provided. Suggestions for future research are discussed.

Surveyed 92 college students to obtain validity estimates for the Career Decision-Making Self-Efficacy Scale. Results of concurrent and discriminant validity studies only partially supported the construct validity of the scale, and the use of individual subscales proved uncertain. (Author/BH)
