Abstract

The Diabetes Care Profile (DCP) was designed to measure psychosocial factors related to diabetes and its treatment. This study sought to determine the reliability and validity of the DCP in Hispanic veterans with Type 2 diabetes. Hispanic (n = 81) and non-Hispanic White (n = 238) patients were recruited at three southwestern VA hospitals. Scale reliabilities calculated by Cronbach's coefficient alpha revealed reliabilities ranging from .54 to .97 in Hispanics and .63 to .95 in non-Hispanic Whites. Only one scale, Monitoring Barriers, differed significantly between the two patient groups. Mean values on the DCP scales were consistent within and across ethnicities lending support for construct validity of the DCP in Hispanics. Convergent validity was also supported for DCP scales within the Hispanic patients as evidenced by correlations in expected directions with external measures.
