To evaluate the psychometric properties of the Caregiver Self-Efficacy in Contributing to Patient Self-Care Scale (CSE-CSC).
The CSE-CSC scale was developed congruently with the Caregiver Contribution to Self-Care of Patient with Chronic Illness Inventory (CC-SC-CII) to assess caregiver self-efficacy (CSE), the motivation factor of caregiving. Its applicability in Asian populations, including Thailand, was limited.
Psychometric tests were guided by COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) principles. This included translating the English version into Thai, following the principles of good practice for the translation and cultural adaptation process for patient-reported outcome (PRO) measures. Nine nursing experts evaluated the content validity. The analysis included caregivers of patients with chronic conditions from 16 primary care centres in Thailand. We tested the structural validity using exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and concurrent validity for CC-SC-CII-v2. We tested the scale's reliability with methods for multidimensional and unidimensional constructs, the intraclass correlation coefficients (ICCs) and measurement error variance.
Kappa coefficient (k = 1.00) indicated the scale's excellent content validity. The final analysis included a total of 407 samples. The EFA with the first split-half subsample (n = 194) extracted a two-dimensional structure. One reflected CSE in Maintenance and Monitoring behaviour and another captured CSE in Management behaviour. CFA with the second split-half subsample (n = 213) and the overall sample (n = 407) supported the scale's bidimensional model with high factor loadings. Each dimension and the overall CSE-CSC scale positively correlated with each scale and the overall CC-SC-CII-v2. McDonald's ω and Cronbach's α (both ranged from 0.91-0.94) indicated excellent internal reliability. Test-retest reliability showed ICCs between 0.95 and 0.96. Measurement error yielded satisfactory results.
Testing of the Thai CSE-CSC scale supported validity and reliability, indicating that the scale can apply to Thai caregivers. This scale can be used in clinical practice and research to evaluate CSE in contribution to patient self-care.
评估患者自我护理贡献的照顾者自我效能量表（CSE-CSC）的心理计量特性。
CSE-CSC 量表是与慢性病患者自我护理照顾者贡献量表（CC-SC-CII）一致开发的，用于评估照顾者自我效能（CSE），这是照顾的动机因素。其在亚洲人群，包括泰国的适用性有限。
心理计量学测试遵循共识基础的健康测量仪器选择标准（COSMIN）原则。这包括将英文版翻译成泰语，遵循患者报告结局（PRO）测量翻译和文化适应性良好实践原则。9 名护理专家评估了内容效度。分析包括来自泰国 16 个初级保健中心的慢性病患者的照顾者。我们使用探索性因子分析（EFA）、验证性因子分析（CFA）和 CC-SC-CII-v2 的同时效度来测试结构效度。我们使用多维和单维结构的方法、组内相关系数（ICC）和测量误差方差来测试量表的可靠性。
kappa 系数（k=1.00）表明量表具有极好的内容效度。最终分析共纳入 407 例样本。EFA 采用第一半样本（n=194）提取了二维结构。一个反映了维护和监测行为的 CSE，另一个反映了管理行为的 CSE。第二半样本（n=213）和总样本（n=407）的 CFA 支持量表的二维模型，因子负荷高。每个维度和总体 CSE-CSC 量表与每个量表和总体 CC-SC-CII-v2 均呈正相关。McDonald's ω 和 Cronbach's α（均在 0.91-0.94 之间）表明具有极好的内部可靠性。测试-重测信度显示 ICC 在 0.95-0.96 之间。测量误差得出了令人满意的结果。
泰国 CSE-CSC 量表的测试支持了有效性和可靠性，表明该量表可适用于泰国照顾者。该量表可用于临床实践和研究，以评估对患者自我护理的贡献的 CSE。
