This study aimed to develop and validate the Dementia Caregiver Positive Feeling Scale 21-item version (DCPFS-21) in Japan.
We selected and generated 27 items based on the preliminary 25-item version of the DCPFS. Next, the DCPFS-21 was developed and validated through two phases. In Phase 1, we obtained data from 147 caregivers of people with dementia by using the 27-item version, examined the construct validity and internal consistency of the scale and then selected 21 items (DCPFS-21). In Phase 2, we compared the scores of 30 caregivers of people with dementia on the DCPFS-21 with the standard scales. Four weeks after the first examination, we re-examined the intra-rater reliability.
In Phase 1, via factor analysis, we reduced the 27 items to 21 items (DCPFS-21). Moreover, the DCPFS-21 was grouped into four subscales, namely, meaning in caregiving, caregiving mastery, positive emotion on caregiving and support from others. This classification agreed with the following factors extracted from the pilot study. The DCPFS-21 showed good internal consistency (Cronbach's α = 0.92). In Phase 2, the DCPFS-21 correlated with the Caregiving Gratification Scale by 0.54 (P < 0.01). The DCPFS-21 also showed good intra-rater reliability (1.1: ρ = 0.62).
We developed and validated the DCPFS-21, which measures the positive feelings of family caregivers of people with dementia, in Japan.
本研究旨在开发并验证日本版的21项痴呆症照料者积极感受量表（DCPFS - 21）。
我们基于DCPFS最初的25项版本筛选并生成了27个条目。接下来，DCPFS - 21分两个阶段进行开发和验证。在第一阶段，我们使用27项版本从147名痴呆症患者的照料者那里获取数据，检验该量表的结构效度和内部一致性，然后选出21个条目（DCPFS - 21）。在第二阶段，我们将30名痴呆症患者照料者在DCPFS - 21上的得分与标准量表进行比较。首次检查四周后，我们重新检验了评分者内信度。
在第一阶段，通过因子分析，我们将27个条目缩减至21个条目（DCPFS - 21）。此外，DCPFS - 21被分为四个子量表，即照料的意义、照料技能、照料中的积极情绪和他人的支持。这一分类与前期研究中提取的以下因素相符。DCPFS - 21显示出良好的内部一致性（克朗巴哈α系数 = 0.92）。在第二阶段，DCPFS - 21与照料满足感量表的相关性为0.54（P < 0.01）。DCPFS - 21还显示出良好的评分者内信度（ICC：ρ = 0.62）。
我们在日本开发并验证了DCPFS - 21，该量表用于测量痴呆症患者家庭照料者的积极感受。
