The Health Managerial Appraisal (HMA) is a competency-based assessment that measures a test-taker’s ability to evaluate interpersonal effectiveness and decision-making capabilities in others. The instrument was developed for assessing managers in Health, Human, and Community Service (HHCS) organizations for skills that are essential to managing staff as they provide person-centered care. This study evaluated the construct validity of the HMA through a correlational method. HMA scores were correlated with the Watson-Glaser Critical Thinking Appraisal, California Psychological Inventory, and Behavioral Observations. The sample included 77 managerial job applicants in the HHCS industry. The results yielded convergent and discriminant evidence that the HMA as a valid measure of these necessary constructs for managing in the HHCS industry. The HMA has potential to be used to inform selection of HHCS managerial applicants as well as help current HHCS managers identify areas for professional development.
