Career Adapt-Abilities Scale: Construction, reliability, and measurement equivalence across 13 countries

Researchers from 13 countries collaborated in constructing a psychometric scale to measure career adaptability. Based on four pilot tests, a research version of the proposed scale consisting of 55 items was field tested in 13 countries. The resulting Career Adapt-Abilities Scale (CAAS) consists of four scales, each with six items. The four scales measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. The CAAS demonstrated metric invariance across all the countries, but did not exhibit residual/strict invariance or scalar invariance. The reliabilities of the CAAS subscales and the combined adaptability scale range from acceptable to excellent when computed with the combined data. As expected, the reliability estimates varied across countries. Nevertheless, the internal consistency estimates for the four subscales of concern, control, curiosity, and confidence were generally acceptable to excellent. The internal consistency estimates for the CAAS total score were excellent across all countries. Separate articles in this special issue report the psychometric characteristics of the CAAS, including initial validity evidence, for each of the 13 countries that collaborated in constructing the Scale.
