The Career-Adaptabilities Scale (CAAS)--Portugal Form consists of four scales, each with seven items, which measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. Internal consistency estimates for the subscale and total scores ranged from good to excellent. The factor structure was fairly similar to the one computed for combined data from 13 countries. The CAAS--Portugal Form includes all the items in the International Form, and it adds one further national item to each scale. The syntheses of a variety of differential studies are presented to illustrate the importance of an adaptability measure to the field of career construction. (Contains 2 tables.)
