Career Adapt-Abilities Scale: Reliability Generalization Meta-Analysis

The concept of career adaptability emerged from the broader field of career development theory and has received increasing attention in the past two decades. To measure career adaptability, there are different scale development studies in the literature, but the most widely used and preferred one is the Career Adapt-abilities Scale developed by Savickas and Porfeli. Therefore, in the present study, the general reliability of the Career Adapt-abilities Scale was measured through meta-analysis. One hundred forty nine study (N = 82519) were included in the analyses. For the CAAS overall score, the average reliability coefficient among the 171 reliability estimations was high. However, reliability estimates in the studies included in the research show high heterogeneity. As a result of the moderator analysis, it was concluded that reliability estimates of these scores differ by item level, culture, language, category of items, different forms of CAAS, age, and SD. Regarding the application of the CAAS in research, the consequences of these findings are discussed in light of the relevant literature.
