Self-management among adolescents with type 1 diabetes (T1D) is poorer than in other age groups during childhood. A valid and reliable short-form scale to measure self-management in adolescents with T1D is prudent for enhancing their self-management in clinical settings. We used a cross-sectional design to develop a short-form Chinese version of the Self-Management of Type 1 Diabetes for Adolescents Scale (C-SMOD-A) and test its psychometric characteristics. Two hundred adolescents with T1D were recruited from four hospitals in Taiwan through convenience sampling. Content validity, exploratory factor analysis, and corrected item-total correlations were used to shorten the 52-item C-SMOD-A. Confirmatory factor analysis, criterion-related validity, and reliability testing were used to examine the psychometric characteristics of the short-form C-SMOD-A. Finally, the 23-item C-SMOD-A (C-SMOD-A-23) with five inter-correlated factors was developed. Glycated hemoglobin levels were significantly associated with each subscale of the C-SMOD-A-23 with correlation coefficients ranging from -0.18 to -0.31. The composite reliability and test-retest reliability of the five subscales ranged from 0.70 to 0.88 and from 0.78 to 0.93 respectively. Accordingly, the C-SMOD-A-23 has acceptable validity and reliability to measure five specific domains of self-management for adolescents with T1D. Health-care providers could use the C-SMOD-A-23 as a clinical reference to assess specific domains of self-management and provide interventions to enhance self-management for adolescents with T1D.
1型糖尿病(T1D)青少年的自我管理能力比儿童期的其他年龄组要差。开发一种有效且可靠的简短量表来测量T1D青少年的自我管理能力,对于在临床环境中提高他们的自我管理能力而言是审慎之举。我们采用横断面设计来开发青少年1型糖尿病自我管理量表(C-SMOD-A)的中文版简表,并测试其心理测量学特征。通过便利抽样从台湾四家医院招募了200名T1D青少年。采用内容效度、探索性因素分析和校正的项目-总分相关来缩短包含52个条目的C-SMOD-A。采用验证性因素分析、效标关联效度和信度测试来检验C-SMOD-A简表的心理测量学特征。最终,开发出了包含23个条目的C-SMOD-A(C-SMOD-A-23),它有五个相互关联的因子。糖化血红蛋白水平与C-SMOD-A-23的每个分量表显著相关,相关系数范围为-0.18至-0.31。五个分量表的组合信度和重测信度分别为0.70至0.88和0.78至0.93。因此,C-SMOD-A-23在测量T1D青少年自我管理的五个特定领域方面具有可接受的效度和信度。医疗保健提供者可以将C-SMOD-A-23用作临床参考,以评估自我管理的特定领域,并为T1D青少年提供干预措施以增强自我管理能力。
