Reliability Generalization: An Examination of the Career Decision-Making Self-Efficacy Scale

The purpose of the present study was to explore the variability in reliability scores on a commonly used career scale, the Career Decision-Making Self-Efficacy Scale (CDMSE). Reliability generalization was employed to identify typical score reliability, variability of score reliability, and variables explaining this variability. Forty-nine pieces of work were examined, and the results revealed that 41% of them reported score reliability of their own data. Of the five subscales, Problem Solving showed the lowest score reliability. In addition, higher score reliability was associated with age, sample racial/ethnic demographics, and standard deviation of total mean score.
