Many caregivers report finding positive meanings in their caregiving roles and activities. The positive aspects of caregiving (PAC) scale was designed to measure positive appraisals of caregiving. This study assessed the reliability and validity of the Korean version of the PAC for family caregivers of people with amyotrophic lateral sclerosis (ALS).
The instrument's content and semantic equivalence were established using translation and back translation of the PAC. A convenience sample of 127 family caregivers of patients with ALS in Korea was recruited. Content, construct, and convergent validity of the Korean PAC were evaluated. Cronbach's α was used to assess reliability. This study used secondary data; the primary study received approval from the Institutional Review Board of H Hospital, from where data were collected. The consent forms did not mention the future use of data. Therefore, we have applied for approval regarding this study's protocol and exemption from informed consent.
The Cronbach's α was 0.92, and internal consistency was acceptable. Exploratory factor analysis supported the construct validity with a two-factor solution explaining 74.73% of the total variance. Regarding convergent validity, the Korean PAC score negatively correlated with caregiver burden and depression and positively with self-rated health status. We were unable to evaluate the suitability of the suggested structural dimensionality through confirmatory factor analysis. Furthermore, as we used secondary data, we could not assess retest reliability for the evaluation of the scale's stability.
The Korean PAC was found to be an applicable instrument with satisfactory reliability and validity and suitable for further use as a measure for positive appraisals of caregiving for family caregivers of people with ALS. It may be effective for measuring caregivers' psychological resources.
许多照顾者报告在他们的照顾角色和活动中找到了积极的意义。积极照顾评估量表（PAC）旨在衡量对照顾的积极评价。本研究评估了韩国肌萎缩侧索硬化症（ALS）患者家属照顾者的 PAC 量表的信度和效度。
使用 PAC 的翻译和回译，确定了工具的内容和语义等效性。本研究在韩国招募了 127 名 ALS 患者的家属照顾者进行便利抽样。评估了韩国 PAC 的内容、结构和收敛效度。使用克朗巴赫α评估信度。本研究使用了二级数据；主要研究获得了 H 医院机构审查委员会的批准，数据就是从那里收集的。同意书并未提及数据的未来用途。因此，我们已申请批准本研究方案并豁免知情同意。
克朗巴赫α为 0.92，内部一致性可接受。探索性因素分析支持具有两个因素的结构效度，可解释总方差的 74.73%。关于收敛效度，韩国 PAC 评分与照顾者负担和抑郁呈负相关，与自我评估的健康状况呈正相关。我们无法通过验证性因素分析评估建议的结构维度的适宜性。此外，由于我们使用了二级数据，因此无法评估重测信度以评估量表的稳定性。
韩国 PAC 被认为是一种具有令人满意的信度和效度的适用工具，适用于进一步作为衡量 ALS 患者家属照顾者积极评价的工具。它可能有助于衡量照顾者的心理资源。
