Caregiver contribution (CC) is important for the self-care behaviors of chronic disease individuals, as it could enhance patient outcomes. Therefore, it is necessary to assess this CC by using a good validity and reliability instrument. The Caregiver Contribution to Self-Care Chronic Illness Inventory (CC-SC-CII) was designed to assess CC to self-care behaviors of patients with chronic illness in Italy. However, it was unclear whether this tool had sound psychometrics properties in the context of Chinese culture. Therefore, we performed the cross-cultural adaption of the CC-SC-CII and we tested its psychometric properties among Chinese caregivers of patients with chronic disease.
A cross-sectional observational design.
Participants were recruited from communities and institutions in Pingdingshan, Henan Province, China.
301 caregivers of care recipients with chronic disease completed the Chinese version of the CC-SC-CII (C-CC-SC-CII).
The content validity index of items (I-CVI), the scale content validity index-average (S-CVI/Ave), exploratory factor analysis, confirmatory factor analysis (CFA), internal consistency and item analysis were tested.
The range of I-CVI was between 0.833 and 1.00, and the score of S-CVI was 0.991. In CFA, the C-CC to self-care monitoring scale had satisfactory fit indices. However, the C-CC to self-care maintenance and management scales had unsupported fit indices. The reliability coefficients of C-CC-SC-CII were 0.792, 0.880 and 0.870 for its three scales. Item-total correlations were all over 0.590. Test-retest reliability showed that the range of intraclass correlation coefficients was from 0.728 to 0.783.
The C-CC-SC-CII has sound psychometrics characteristics and is a culturally appropriate and reliable instrument for assessing CC to the self-care behaviours of patients with chronic disease in China.
照顾者的贡献（CC）对于慢性病患者的自我护理行为很重要，因为它可以改善患者的结局。因此，有必要使用具有良好有效性和可靠性的工具来评估这种 CC。《照顾者对慢性病自我护理贡献量表》（CC-SC-CII）旨在评估意大利慢性病患者自我护理行为的 CC。然而，尚不清楚该工具在中国文化背景下是否具有良好的心理计量学特性。因此，我们对 CC-SC-CII 进行了跨文化调适，并在中国慢性病患者的照顾者中测试了其心理计量学特性。
一项横断面观察性设计。
参与者来自中国河南省平顶山市的社区和机构。
301 名慢性病照顾者完成了中文版的 CC-SC-CII（C-CC-SC-CII）。
项目内容效度指数（I-CVI）、量表内容效度指数平均值（S-CVI/Ave）、探索性因子分析、验证性因子分析（CFA）、内部一致性和项目分析。
I-CVI 的范围为 0.833 至 1.00，S-CVI 的得分为 0.991。在 CFA 中，C-CC 对自我护理监测量表具有较好的拟合指数。然而，C-CC 对自我护理维持和管理量表的拟合指数支持不足。C-CC-SC-CII 的信度系数为 0.792、0.880 和 0.870，分别为其三个分量表。项目总分相关性均大于 0.590。重测信度显示，组内相关系数的范围为 0.728 至 0.783。
C-CC-SC-CII 具有良好的心理计量学特征，是一种文化适宜且可靠的工具，可用于评估中国慢性病患者的 CC 对自我护理行为的影响。
