A variety of diabetes self-management instruments have been developed but few of them consist of the preparedness for diabetes self-management behavior. The novel psychometric evaluation tool "the LMC Skills, Confidence & Preparedness Index (SCPI)" measures three key aspects of a patient's diabetes self-management: knowledge of the skill, confidence in being able to perform skill and preparedness to implement the skill. The objective of this study was to translate, adapt and validate the SCPI for use in Chinese adult patients with type 2 diabetes.
This study followed the guideline recommended by the American Academy of Orthopaedic Surgeons Evidence Based Medicine Committee (AAOS) to indigenize the scale. Forward and back translation, and cross-cultural language debugging were completed according to the recommended steps. A convenience sample of Chinese patients with type 2 diabetes (n = 375) were recruited from a university-affiliated hospital in Shanghai. The validity (criterion, discriminant validity, and construct validity), reliability (internal consistency and test-retest reliability) and the interpretability of the instrument were examined. The content validity was calculated by experts' evaluation.
The Chinese version of SCPI (C-SCPI) has good internal consistency with a Cronbach's alpha of 0.92. The ceiling effects of the preparedness subscales is 21%. The criterion validity of three dimensions of C-SCPI was established with significantly moderate correlations between the DKT, DES-SF and SDSCA (p < 0.05). The S-CVI of the whole scale was 0.83. Except for entry 21, the I-CVI values of all entries were greater than 0.78. The C-SCPI has also shown good discriminative validity with statistically significant differences between the patients with good and poor glycemic control. Confirmatory factor analysis showed that modified results indicate that the fitting degree of the model is good, χ/df = 2.775, RMSEA = 0.069, CFI = 0.903, GFI = 0.873, TLI = 0.889, IFI = 0.904. The test-retest reliability coefficient was 0.61 (p < 0.01).
We established a Chinese version of SCPI through translation and cross-cultural adaptation. The C-SCPI is reliable and valid for assessment of the level of self-management in Chinese patients with type 2 diabetes.
已经开发出各种糖尿病自我管理工具，但其中很少有工具包含糖尿病自我管理行为的准备情况。新颖的心理测量评估工具“LMC 技能、信心和准备指数（SCPI）”衡量患者糖尿病自我管理的三个关键方面：技能知识、执行技能的信心和实施技能的准备情况。本研究的目的是翻译、改编和验证 SCPI，使其可用于中国成年 2 型糖尿病患者。
本研究遵循美国矫形外科医师学会循证医学委员会（AAOS）推荐的指南对量表进行本土化。根据推荐步骤完成了正向和反向翻译以及跨文化语言调试。从上海一所大学附属医院招募了 375 名方便的中国 2 型糖尿病患者作为研究对象。检验了该工具的有效性（标准、判别有效性和结构有效性）、信度（内部一致性和重测信度）和可解释性。通过专家评估计算了内容效度。
SCPI 的中文版（C-SCPI）具有良好的内部一致性，克朗巴赫系数为 0.92。准备分量表的天花板效应为 21%。C-SCPI 的三个维度的标准有效性得到确立，DKT、DES-SF 和 SDSCA 之间存在显著中度相关性（p<0.05）。整个量表的 S-CVI 为 0.83。除条目 21 外，所有条目的 I-CVI 值均大于 0.78。C-SCPI 还具有良好的判别有效性，血糖控制良好和不佳的患者之间存在统计学显著差异。验证性因子分析表明，修正后的结果表明模型拟合度良好，χ/df=2.775，RMSEA=0.069，CFI=0.903，GFI=0.873，TLI=0.889，IFI=0.904。重测信度系数为 0.61（p<0.01）。
我们通过翻译和跨文化适应建立了 SCPI 的中文版。C-SCPI 可靠且有效，可用于评估中国 2 型糖尿病患者的自我管理水平。
