Self-care in adults with sickle cell disease.

This article summarizes the psychometric evaluation of the Chronic Illness Assessment Interview for Sickle Cell Disease (CIAI-SCD), an instrument based on a model of self-care for adult patients with chronic medical conditions. The CIAI-SCD was administered to 104 adults with sickle cell disease. A factor analysis identified three factors that reflected the psychological constructs of Personal Satisfaction and Perceived Control (Factor 1), Feeling Concerned and Worried (Factor 2), and Feeling Supported (Factor 3). Preliminary evidence for the internal consistency, test-retest reliability content validity, and construct validity of the CIAI-SCD was obtained. After further refinement and validation, the CIAI-SCD may be a useful tool for assessing factors related to self-care skills among adults with sickle cell disease.
