目的-本研究的目的是评估糖尿病赋权量表（DES）的有效性、可靠性和实用性，该量表是糖尿病相关心理社会自我效能的衡量标准。研究设计和方法-在本研究中（n = 375），计算了DES的心理测量特性。为了建立有效性，DES分量表与糖尿病护理概况（DCP）的2个先前验证的分量表进行比较。进行因素和项目分析，以开发子量表，是连贯的，有意义的，并有一个可接受的系数α。结果-心理测量学分析导致了28项DES（α = 0.96），包含3个分量表：管理糖尿病的心理社会方面（α = 0.93），评估不满意和准备改变（α = 0.81），以及设定和实现糖尿病目标（α = 0.91）。DES分量表和DCP分量表之间的预期方向一致的相关性提供了证据的并发validity.CONCLUSIONS -这项研究提供了初步证据表明，DES是一个有效的和可靠的措施糖尿病相关的心理社会自我效能。DES应该是一个有用的结果措施，各种教育和心理社会干预有关糖尿病。
OBJECTIVE - The purpose of this study was to assess the validity, reliability, and utility of the Diabetes Empowerment Scale (DES), which is a measure of diabetes-related psychosocial self-efficacy.RESEARCH DESIGN AND METHODS - In this study (n = 375), the psychometric properties of the DES were calculated. To establish validity, DES subscales were compared with 2 previously validated subscales of the Diabetes Care Profile (DCP). Factor and item analyses were conducted to develop subscales that were coherent, meaningful, and had an acceptable coefficient alpha.RESULTS - The psychometric analyses resulted in a 28-item DES (alpha = 0.96) with 3 subscales: Managing the Psychosocial Aspects of Diabetes (alpha = 0.93), Assessing Dissatisfaction and Readiness To Change (alpha = 0.81), and Setting and Achieving Diabetes Goals (alpha = 0.91). Consistent correlations in the expected direction between DES subscales and DCP subscales provided evidence of concurrent validity.CONCLUSIONS - This study provides preliminary evidence that the DES is a valid and reliable measure of diabetes-related psychosocial self-efficacy. The DES should be a useful outcome measure for various educational and psychosocial interventions related to diabetes.
