Post-stroke complications affect the informal caregivers equally as the stroke survivors, especially those who have a moderate to worst prognosis in functional capacity recovery. Caregiver Assessment of Function and Upset (CAFU) is one of the common tools used in both research and clinical practice to measure the patient's dependency level and the stroke caregivers' upset level.
This study aimed to translate and validate the CAFU instrument into the Malay language and test the validity and reliability of the CAFU among informal stroke caregivers in Malaysia.
A standard forward-backward translation method was employed to translate CAFU. Subsequently, 10 expert panels were included in the validation process, and thereafter reliability testing was conducted among 51 stroke caregivers. The validation of the instrument was determined by computing the content validity indices (CVIs), and we used the Cronbach's alpha method to explore the internal consistency of the overall score and subscales scores of the Malay-CAFU. Finally, the explanatory factor analysis used principal component extraction and a varimax rotation to examine construct validity.
All items of the Malay-CAFU had satisfactory item-level CVI (I-CVI), with values greater than 0.80, and the scale-level CVI (S-CVI) was 0.95. These results indicate that the Malay-CAFU had good relevancy. The internal consistency for the reliability test showed a Cronbach's alpha value of 0.95 for the overall score. The eigenvalues and scree plot supported a two-factor structural model of the instrument. From the explanatory factor analysis, the factor loadings ranged from 0.82 to 0.90 and 0.56 to 0.83, respectively.
The Malay-CAFU questionnaire is a valid and reliable instrument to assess the dependence level of stroke survivors and the upset level of informal stroke caregivers in Malaysia.
中风后的并发症不仅会影响中风幸存者，还会影响他们的非专业照顾者，尤其是那些在功能能力恢复方面预后中等或较差的患者。照顾者评估功能和烦恼量表（CAFU）是一种在研究和临床实践中常用的工具，用于测量患者的依赖程度和中风照顾者的烦恼程度。
本研究旨在将 CAFU 量表翻译成马来语并验证其在马来西亚非专业中风照顾者中的有效性和可靠性。
采用标准的正向翻译和反向翻译方法对 CAFU 进行翻译。随后，邀请 10 位专家小组参与验证过程，然后对 51 名中风照顾者进行可靠性测试。通过计算内容有效性指数（CVI）来确定工具的验证情况，我们使用克朗巴哈的 alpha 方法来探索马来语-CAFU 的总分和子量表得分的内部一致性。最后，使用主成分提取和方差极大旋转进行解释性因子分析，以检验结构有效性。
马来语-CAFU 的所有项目均具有满意的项目水平 CVI（I-CVI），其值均大于 0.80，量表水平 CVI（S-CVI）为 0.95。这些结果表明马来语-CAFU 具有良好的相关性。可靠性测试的内部一致性显示，总分的克朗巴哈的 alpha 值为 0.95。特征值和碎石图支持该工具的两因素结构模型。从解释性因子分析来看，因子负荷范围分别为 0.82 至 0.90 和 0.56 至 0.83。
马来语-CAFU 问卷是一种有效且可靠的工具，可用于评估马来西亚中风幸存者的依赖程度和非专业中风照顾者的烦恼程度。
