The objective of this study was to translate the Barriers to Insulin Treatment Questionnaire (BIT) into Chinese and test its psychometric properties in middle-aged and elderly type 2 diabetes mellitus (T2D) patients using insulin in the Han people of urban China.
We established the Barriers to Insulin Treatment Questionnaire in Chinese (BIT-C). We selected 296 patients with T2D for testing BIT-C's the reliability and validity, of which 120 patients were retested four weeks later. Another 200 patients with T2D were selected to perform the confirmatory factor analysis (CFA).
The final BIT-C consisted of 11 items (BIT-C-11) and four factors. The explained variances of the BIT-C-11 and its four factors were 90.153%, 51.308%, 18.810%, 10.863%, and 9.173%. CFA validated that the four-factor model fit with the data of the BIT-C-11. Standardized factor loadings ranged between 0.77 and 0.90. The Cronbach's α coefficients of the BIT-C-11 and its four factors were 0.903, 0.952, 0.927, 0.938, and 0.917. Correlation analysis was performed between the BIT-C-11 and General Adherence Scale in Chinese (GAS-C) to calculate the criterion-related validity (r = 0.598, p < 0.001). The correlation coefficient r of the BIT-C-11's test-retest reliability was 0.810 (p < 0.001).
The BIT-C-11 has good reliability and validity. It can be used for psychological resistance to insulin therapy studies of middle-aged and elderly patients with T2D using insulin in the Han people of Chinese cities.
本研究旨在将胰岛素治疗障碍问卷（BIT）翻译成中文，并在中国城市汉族中老年2型糖尿病（T2D）胰岛素治疗患者中测试其心理测量学特性。
我们建立了中文版胰岛素治疗障碍问卷（BIT-C）。选取296例T2D患者测试BIT-C的信效度，其中120例患者在4周后进行重测。另选取200例T2D患者进行验证性因子分析（CFA）。
最终的BIT-C由11个条目（BIT-C-11）和4个因子组成。BIT-C-11及其4个因子的解释方差分别为90.153%、51.308%、18.810%、10.863%和9.173%。CFA验证了四因子模型与BIT-C-11的数据拟合良好。标准化因子载荷在0.77至0.90之间。BIT-C-11及其4个因子的Cronbach's α系数分别为0.903、0.952、0.927、0.938和0.917。对BIT-C-11与中文版一般依从性量表（GAS-C）进行相关分析以计算效标关联效度（r = 0.598，p < 0.001）。BIT-C-11重测信度的相关系数r为0.810（p < 0.001）。
BIT-C-11具有良好的信效度。可用于中国城市汉族中老年T2D胰岛素治疗患者胰岛素治疗心理阻力的研究。
