Reliability and validation of the Positive Aspects of Caregiving scale among Japanese caregivers of people with dementia.
Hidetoshi Furukawa, Chieko Greiner
PMID 33997136WHAT IT FOUND
Dementia caregivers' Japanese nine-item positive aspects scale, tested in 194 caregivers, had consistent scores and was linked with lower depression, but its item grouping differed from the original.
It may help nurses assess caregiver strengths, not show a care outcome improved.
Key findings
01The nine-item scale had internal consistency of 0.895 and subscale alphas of 0.896 and 0.823.
02PAC scores had a significant negative correlation with Geriatric Depression Scale scores (r = -0.548, P < 0.01).
03Factor analysis found two factors, Living an enriched life and Self-usefulness, and this construct differed from the original model.

What it does not show
The response rate was low: 199 responses were received from 2,825 mailed questionnaires (7.0%), and the authors say selection bias cannot be ruled out. The sample was analysed as 194 caregivers after 5 were excluded, and it came only from Japan's Kinki region, which involves six of 47 prefectures. Test-retest reliability was checked in only 53 caregivers. Only the first author translated the scale, so cross-cultural adaptation may not have been sufficiently tested. The factor structure differed from the original scale, so the Japanese version is not simply the same two-factor model.
Declared interests
This work was supported by Kansai University of Nursing and Health Sciences and JSPS KAKENHI. The funding sponsor had no involvement. The authors declare no conflict of interest.
The easy way to misread this
Do not assume this scale has been shown to improve caregiver or patient outcomes. It was validated only as an assessment tool in 194 Japanese caregivers, and its factor structure differed from the original scale.
