Abstract

OBJECTIVE

This study assessed the psychometric properties of the Caring Efficacy Scale (CES) among personal care attendants providing care to older residents in residential aged care settings.

METHODS

This cross-sectional study was completed in Australia in 2020-2021. Confirmatory factor analysis (CFA) of the 30-item original CES (Model 1) and 28-item CES validated in registered nurses (Model 2) was conducted to assess the goodness of fit of these models in our study population. Due to unsatisfactory fit indices for both models, exploratory factor analysis (EFA) was conducted to examine the dimensionality and underlying structure of the original CES among personal care attendants. Internal consistency of the final scale and subscales identified was examined using item-total correlations and Cronbach's alpha coefficients.

RESULTS

Two hundred and eighty personal care attendants participated in the study. The model fit indices such as Comparative Fit Index and Tucker Lewis Index of both models were less than 0.90, while the Standardised Root Mean Square Residual and Root Mean Square of Approximation values were greater than or equal to 0.08 and 0.06, respectively. The EFA identified a two-factor structure, and 22 items of the 30 in the original scale were retained. Item-total correlations amongst items retained in the scale and subscales were greater than 0.3. Cronbach's alpha for the abbreviated scale was 0.85, with 0.83 and 0.79, respectively, for the two subscales.

CONCLUSIONS

The modified CES can be used as a robust tool to assess the self-efficacy of personal care attendants in providing care to older residents in residential aged care settings.

摘要

目的

本研究评估了关爱效能感量表（CES）在为居住在养老院的老年居民提供护理的个人护理员中的心理测量学特性。

方法

这是一项 2020-2021 年在澳大利亚进行的横断面研究。对 30 项原始 CES（模型 1）和经过注册护士验证的 28 项 CES（模型 2）进行验证性因子分析（CFA），以评估这些模型在我们研究人群中的拟合优度。由于两个模型的拟合指数均不理想，因此进行了探索性因子分析（EFA），以检验原始 CES 在个人护理员中的维度和潜在结构。使用项目总分相关和克朗巴赫 α 系数检验最终确定的量表和子量表的内部一致性。

结果

共有 280 名个人护理员参加了研究。两个模型的模型拟合指数，如比较拟合指数和塔克-刘易斯指数均小于 0.90，而标准化根均方残差和逼近值的根均方分别大于或等于 0.08 和 0.06。EFA 确定了一个两因素结构，原始量表中的 30 个项目中有 22 个被保留。保留在量表和子量表中的项目的项目总分相关大于 0.3。缩写量表的克朗巴赫 α 为 0.85，两个子量表的克朗巴赫 α 分别为 0.83 和 0.79。
