To develop and psychometrically test Character Strengths Use in Diabetes Self-management Scale in people with type 2 diabetes.
Cross-sectional design.
Based on literature reviews and examination by experts, a 20-item scale was developed and administered to 350 participants with type 2 diabetes who were enrolled from two endocrine clinics by convenience sampling in Taiwan. Item analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), concurrent and predictive validity as well as reliability were used to examine the psychometric characteristics of the scale. Data were collected from November 2021 to March 2022.
EFA and CFA supported a 12-item scale with three factors, namely learning proactively, taking on challenges and thinking positively, fit the data well. The total score of the 12-item scale significantly and positively correlated with diabetes-specific quality of life, and significantly and negatively correlated with baseline and 9-month haemoglobin A1c levels. Cronbach's α for overall scale and subscales ranged between .78 and .91.
The 12-item Character Strengths Use in Diabetes Self-management Scale demonstrated satisfactory validity and reliability in people with type 2 diabetes.
Nurses could apply this new scale to identify the degree of using character strengths in self-management in people with type 2 diabetes; accordingly, character strength-based interventions could be provided to improve self-management in such patients with diabetes. Furthermore, the 12-item Character Strengths Use in Diabetes Self-management Scale has the potential to be used to measure the effectiveness of strength-based interventions in people with Type 2 diabetes.
Five patients with type 2 diabetes were invited to take the original 20-item scale to evaluate the clarity, readability and comprehensiveness of the 20 items.
开发并对 2 型糖尿病患者的糖尿病自我管理中性格优势应用量表进行心理测量学检验。
横断面设计。
基于文献回顾和专家检查，开发了一个 20 项的量表，并通过便利抽样从台湾的两家内分泌诊所招募了 350 名 2 型糖尿病患者进行测试。采用项目分析、探索性因子分析（EFA）、验证性因子分析（CFA）、同时和预测效度以及信度来检验量表的心理测量特性。数据收集于 2021 年 11 月至 2022 年 3 月。
EFA 和 CFA 支持一个具有三个因子的 12 项量表，即积极主动地学习、迎接挑战和积极思考，该量表很好地拟合了数据。12 项量表的总分与糖尿病特定生活质量显著正相关，与基线和 9 个月的糖化血红蛋白水平显著负相关。总体量表和分量表的克朗巴赫α系数在.78 到.91 之间。
12 项性格优势在糖尿病自我管理中的应用量表在 2 型糖尿病患者中具有较好的效度和信度。
护士可以应用这个新量表来确定 2 型糖尿病患者在自我管理中使用性格优势的程度；相应地，可以为这些糖尿病患者提供基于性格优势的干预措施，以改善自我管理。此外，12 项性格优势在糖尿病自我管理中的应用量表具有潜力，可用于衡量基于优势的干预措施在 2 型糖尿病患者中的效果。
邀请了 5 名 2 型糖尿病患者来测试原始的 20 项量表，以评估 20 项的清晰度、可读性和全面性。
