The purpose of this study was to develop and psychometrically test a new instrument for measuring self-management of adults with type 2 diabetes. Data were collected from 634 diabetic adults recruited from three teaching hospitals in Taiwan. Construct validity was determined by confirmatory factor analysis (CFA). Tests of internal consistency and test-retest were used to assess the reliability of the diabetes self-management instrument (DSMI). Initial results of CFA did not fully support the proposed five-factor model. After the model was modified, the fit indices indicated that this model fits the data best. This model was further cross validated in a second sample. Cronbach's alpha coefficient of the DSMI total scale was .94. The test-retest correlations for the DSMI total scale were acceptable (r = .73, p < .01).
本研究的目的是开发并对一种用于测量2型糖尿病成年患者自我管理能力的新工具进行心理测量学测试。数据收集自台湾三所教学医院招募的634名糖尿病成年患者。通过验证性因子分析（CFA）确定结构效度。使用内部一致性检验和重测法来评估糖尿病自我管理工具（DSMI）的信度。CFA的初步结果并未完全支持所提出的五因素模型。在对模型进行修改后，拟合指数表明该模型最适合数据。该模型在第二个样本中进一步进行了交叉验证。DSMI总量表的Cronbach's alpha系数为0.94。DSMI总量表的重测相关性是可接受的（r = 0.73，p < 0.01）。
