The Reliability and Validity of the Diabetes Care Profile for Chinese Populations

摘要

This study aimed to translate into Chinese the Diabetes Care Profile (DCP), a measure of psychosocial factors and diabetes treatment, and to test the reliability and validity of the instrument within a Chinese population. The English version of the DCP was translated into Chinese following the standard translation methodology with consideration to cultural adaptation. The questionnaire was administered to 313 people with type 2 diabetes in an urban community in Beijing, China. Cronbach's coefficient was used to calculate reliabilities, which ranged from .55 to .86 on DCP subscales. Mean values on the DCP differed by diabetes treatment as expected and supports the construct validity of the DCP. The overall score on the DCP correlated well both with blood glucose levels and with a validated measure of a Chinese version of the Diabetes Specific Quality of Life scale, thus supporting the DCP's criterion validity. The DCP is an acceptable measure of the psychosocial factors related to diabetes and its treatment in a Chinese population with type 2 diabetes.
