The current paper presents the findings from the reliability and validity testing of an 18-item Diabetes Self-efficacy Scale derived from the 28-item Insulin Management Diabetes Self-efficacy Scale. Testing in the Australian context occurred at three points over 9 months. Diabetes self-efficacy is defined as the individual's judgement of confidence to carry out tasks specific to diabetes management. Data were obtained from an Australian metropolitan sample of adult, English speaking men and women with diabetes (N = 226). Participants were insulin-using and non-insulin-using. Factor analysis indicated five subscales. The data support the construct validity and reliability of the 18-item scale in terms of stability, internal consistency and item-total correlation matrices. This study provides consistent evidence that the Diabetes Self-efficacy Scale is a valid and reliable measure over time when the individual's efficacy beliefs are changing. Hence this instrument should be a useful outcome measure for educational diabetes related interventions.
本文介绍了一项源自28项胰岛素管理糖尿病自我效能量表的18项糖尿病自我效能量表的信效度测试结果。在澳大利亚进行的测试在9个月内分三个阶段进行。糖尿病自我效能被定义为个体对执行糖尿病管理特定任务的信心判断。数据来自澳大利亚一个大都市地区的成年糖尿病患者样本，这些患者讲英语，包括男性和女性（N = 226）。参与者既有使用胰岛素的，也有不使用胰岛素的。因子分析表明存在五个子量表。数据在稳定性、内部一致性和项目与总分相关矩阵方面支持了该18项量表的结构效度和信度。这项研究提供了一致的证据，表明当个体的效能信念发生变化时，糖尿病自我效能量表在一段时间内是一种有效且可靠的测量工具。因此，该工具对于与糖尿病相关的教育干预应该是一种有用的结果测量指标。
