Background: China was projected to have the highest increase in the prevalence of diabetes from 1995 to 2025 (King, Aubert, & Hermna, 1998). Development of culturally relevant diabetes self-management (DSM) programs is a priority for China. The first step is the use of reliable and valid instruments that measure DSM and its influencing factors among Chinese patients with diabetes. Some instruments on DSM have been developed and tested in American patients with diabetes. However, the reliability and validity of these instruments have not been determined for Chinese patients with diabetes. Purpose: The purpose of the study was to test the reliability and validity of a series of instruments relevant to DSM in Chinese patients with type 2 diabetes. Method: The sample consisted of 30 Chinese patients with type 2 diabetes at a major hospital in Beijing China who completed a survey assessing DSM, diabetes self-efficacy, family support, and provider-patient communication. The content validity of the scales was evaluated for relevance and clarity by a panel of four experts in diabetes who can read both English and Chinese. Confirmatory factor analysis was conducted to evaluate the construct validity. Cronbach's alpha was calculated to evaluate the reliability of the instruments. Results: The DSM and self-efficacy scales had content validity index (CVI) scores higher than .90. The family support and provider-patient communication scales for clarity had CVI scores lower than .80. The items were revised based on the scores and the suggestions. For the four instruments, the Cronbach's alpha varied from .67 to .87. The variances explained by factors varied from 42% to 97.9% and the factor loadings from .334 to .943. Implications to practice: The findings of this investigation into the psychometric properties of the four instruments are promising. These results support the use of these instruments by public health nurses in China to assess the level of DSM and the influences of diabetes self-efficacy, family support, and provider-patient communication on DSM, which will help in the development of effective interventions that promote DSM in Chinese patients with type 2 diabetes.

Learning Objectives: At the conclusion of this session, the learner will be able to

• Discuss the need for reliable and valid instruments to obtain evidence for practice;
• Articulate the procedure for the use of an English instrument in China;
• List one measure for reliability and two measures for validity for validating for measuring diabetes self-management, diabetes self-efficacy, family support, and provider-patient communication
