BACKGROUND This study was initiated to examine the psychometric components of the Diabetes Empowerment Scale (DES) by translating and validating the scale into the Malay language (DES-M) which is the main language spoken in Malaysia. This study can determine the level of empowerment among diabetic patients towards diabetes management. In addition, the reliability and validity of the DES-M was also demonstrated. METHODS A total of 151 patients with type 2 diabetes mellitus were recruited (between June 2016 and October 2016) to complete sets of questionnaires, which were DES-M, the Malay versions of the Diabetes Quality of Life (DQOL) for Adults and Summary of Diabetes Self Care Activities Questionnaire (SDSCA). Confirmatory and Exploratory factor analysis (CFA and EFA) were carried out to determine the factor structures of the DES-M. RESULTS There were 100 males and 51 females with ages ranging from 19 to 81 years old (55 ± 13) included in this study. The instrument displayed good internal consistency (Cronbach's α =0.920) and the respective coefficients ranged from 0.65-0.84. Discriminant validity showed adequate correlations ranged from 0.257-0.744. Concurrent validity with SDSCA (Pearson's correlation = 0.313, p = 0.012). Predictive validity with DQOL (B = 0.27, p = 0.016). CFA indicated that four factor model of the DES-M has good fit to the data. CONCLUSION This study indicates that the DES-M has a good internal consistency and validity. Therefore, it is a valid and reliable instrument for assessing empowerment score among patients with diabetes in Malaysia. TRIAL REGISTRATION NMRR-16-805-30503 (IIR).

使用探索性因子分析的医院Serdang 2型糖尿病患者的马来版糖尿病赋权量表的心理计量学特性。

背景技术本研究的开始是通过翻译和验证该量表到马来西亚使用的主要语言马来语（DES-M）来检查糖尿病权能量表（DES）的心理计量学组成部分。这项研究可以确定糖尿病患者对糖尿病管理的赋权水平。此外，还证明了DES-M的可靠性和有效性。方法（2016年6月至2016年10月），共纳入151名2型糖尿病患者，以完成DES-M，马来版成人糖尿病生活质量（DQOL）和糖尿病自我护理活动调查表（SDSCA）。进行了验证性和探索性因素分析（CFA和EFA）来确定DES-M的因素结构。结果本研究纳入了100例男性和51例女性，年龄在19至81岁之间（55±13）。仪器显示出良好的内部一致性（Cronbach'sα= 0.920），各个系数的范围为0.65-0.84。判别有效性显示出足够的相关性，范围从0.257-0.744。与SDSCA并发有效（皮尔森相关系数= 0.313，p = 0.012）。使用DQOL的预测有效性（B = 0.27，p = 0.016）。CFA指出，DES-M的四因素模型与数据非常吻合。结论本研究表明DES-M具有良好的内部一致性和有效性。因此，它是评估马来西亚糖尿病患者赋权得分的有效和可靠工具。试用注册NMRR-16-805-30503（IIR）。
