Abstract

Objective

This study aimed to develop and validate a scale for measuring the care competency of family caregivers in home palliative care (CCSHPC).

Methods

The initial version was established based on the model for caregiver skill building/effectiveness, literature review, qualitative research, expert consultations, and quantitative research. The measurement properties included content validity, structural validity, internal consistency, reliability, measurement error, and construct validity. The survey included 381 family caregivers who had previously or were currently receiving home palliative care services in Shanghai.

Results

The final scale comprised 29 items across 6 dimensions: care knowledge, daily care skills, special care skills, caregiving qualities, self-care practices, and the acquisition of social supports and resources. The cumulative variance contribution rate was 75.406%. Confirmatory factor analysis showed good model fit (χ² = 767.146, df = 357, χ²/df = 2.149, root mean square of approximation error = 0.074, root mean square residual = 0.063, incremental fitting index = 0.904, comparative fit index = 0.903). The content validity at the scale and item levels were 0.97 and 0.86 to 1.00, respectively. The reliability of the scale was acceptable (Cronbach's α = 0.954, McDonald's Omega = 0.959, split-half reliability = 0.886, test-retest reliability = 0.931). The standard error of measurement was 4.38.

Conclusions

The scale is reliable and valid, and it can be applied to measure the care competency of family caregivers in home palliative care, providing a reference for medical professionals to develop targeted intervention strategies. However, the applicability of the scale among family caregivers in different cultural and social contexts, as well as the validation of other measurement properties of the scale, requires further research.

家庭姑息治疗中家庭照顾者护理能力量表的开发与心理测量学评估

目的编制家庭姑息治疗家庭照护者护理能力量表，并对量表进行验证。方法采用照护者技能培养/效果模型、文献回顾、定性研究、专家咨询、定量研究等方法建立初版。测量属性包括内容效度、结构效度、内部一致性、信度、测量误差和结构效度。调查对象包括381名曾经或目前在上海接受过家庭姑息治疗的家庭照顾者。结果最终量表包括护理知识、日常护理技能、特殊护理技能、护理质量、自我护理实践、社会支持和资源获取6个维度共29个项目。累积方差贡献率为75.406%。验证性因子分析显示，模型拟合良好（χ2 = 767.146, df = 357, χ2/df = 2.149，近似均方根误差= 0.074，均方根残差= 0.063，增量拟合指数= 0.904，比较拟合指数= 0.903）。量表和项目水平的内容效度分别为0.97和0.86 ~ 1.00。量表信度可接受（Cronbach's α = 0.954, McDonald's Omega = 0.959，劈半信度= 0.886，重测信度= 0.931）。测定标准误差为4.38。结论该量表可靠有效，可用于衡量家庭照护者在居家姑息治疗中的护理能力，为医护人员制定有针对性的干预策略提供参考。然而，该量表在不同文化和社会背景下对家庭照顾者的适用性，以及该量表的其他测量属性的验证，都需要进一步的研究。
