No scales measure self-efficacy in women with Type 2 diabetes. A scale was developed and tested.
Items generated, content validity index (CVI) assessed by experts, the 2-part Diabetes Self-Efficacy Scale (DSLF-I and DSLF-II) was piloted with 62 women, administered to 208 women, and then readministered to 30 women to determine initial reliability. Factor analysis was conducted for construct validity. Discriminant, convergent, and predictive validity was examined.
The CVI index was 98%. Cronbach's alphas were 0.88 (DSLF-I) and 0.82 (DSLF-II; pilot) and 0.87 and 0.86, respectively (main study); test-retest correlation was .60 (DSLF-I) and .69 (DSLF-II). There were 3 factors that emerged: diabetes knowledge of self-care activity, diabetes diet self-care, and diabetes medication self-care.
The Diabetes Self-Efficacy Scale demonstrates good initial reliability and validity.
尚无量表可用于测量2型糖尿病女性的自我效能感。因此开发并测试了一种量表。
生成条目，由专家评估内容效度指数（CVI），对两部分组成的糖尿病自我效能量表（DSLF - I和DSLF - II）在62名女性中进行预试验，施用于208名女性，然后再次施用于30名女性以确定初始信度。进行因子分析以检验结构效度。检验区分效度、聚合效度和预测效度。
CVI指数为98%。克朗巴哈系数在预试验中DSLF - I为0.88，DSLF - II为0.82，在主要研究中分别为0.87和0.86；重测相关性DSLF - I为0.60，DSLF - II为0.69。出现了3个因子：自我护理活动的糖尿病知识、糖尿病饮食自我护理和糖尿病药物自我护理。
糖尿病自我效能量表显示出良好的初始信度和效度。
