Validation of the Japanese version of the quality of life-Alzheimer's disease for nursing homes.

OBJECTIVES: This study aims to validate the Japanese version of Quality of Life-Alzheimer's Disease for Nursing Homes (QOL-AD NH). This is the modified version of QOL-AD, initially developed for residents living with dementia in long-term care settings. METHODS: Psychometric assessment was conducted in a sample of 101 residents and their professional care staff to obtain self-ratings and proxy-ratings of QOL, respectively. Residents' behavior was observed using Dementia Care Mapping (DCM) method, and their mood/engagement (ME) value was evaluated as a proxy measure of QOL. RESULTS: Self-ratings were higher than proxy-ratings (t = 10.22, p<.001), with moderate correlation (r=.51, p<.001) and strong internal consistency (α=.87 for both). The exact agreement between the two groups was 38.23%. Convergent validity was confirmed with ME value and positive engagements of DCM. Exploratory factor analysis was performed for further validity testing. Three factors - self and life overall, social environment, and physical and psychological health, accounted for 85.9% of the total variance with Cronbach's α of .87, .73, .90, respectively. CONCLUSION: Using a validated Japanese version of the QOL-AD NH may help assess the QOL of older residents living in long-term care settings to improve the continuum of care for dementia.

Japanese Translation and Validation of the Environmental Assessment Tool-Higher Care.

OBJECTIVE: The purpose of this study was to translate the Environmental Assessment Tool-Higher Care (EAT-HC) into Japanese and validate its use in small-scale group living facilities in Japan. BACKGROUND: Environment of a facility is shown to improve its residents' quality of life (QOL). Japan's "welfare-based nursing homes for the elderly" are gradually shifting to a small-scale group living concept called group care units (GCUs). However, there is no appropriate environmental tool available for evaluating GCUs. The application of valid environmental assessment tools brings about a better understanding of the nature of good environments and the relationship between environments and outcomes for residents living with dementia. METHODS: The study had a mixed method design conducted in several steps, covering translation and adaptation. The translation phase involved (1) forward translation and (2) backward translation. The adaptation phase involved (3) content validity and homogeneity reliability and (4) concurrent validity and interrater reliability. RESULTS: 71 Items (92%) met the acceptable level of content validity (item-content validity index [CVI] > .79) and had good scale-CVI of .88. Concurrent validity was confirmed between .65 and .78 (p < .001). For reliability test, the internal consistency of six subscales was between .88 and .98. Overall interobserver agreement was 90.3%. Intraclass correlation coefficients were .80-.98 (p < .001), and homogeneity reliability coefficient for all items was >.76 (p < .01). CONCLUSIONS: Validation of the EAT-HC-Japanese Version (EAT-HC-JV) was confirmed as an appropriate tool for environmental assessment to enhance the QOL in Japan's GCUs. For future study, we plan to modify the EAT-HC-JV to adapt to Japanese cultural aspects in order to increase its usability in Japan.

[The influence of types of living alone on 2-year health changes according to elderly adults' marital status: Based on the Comprehensive Regional Studies for Preventing Isolation of the Elderly Who Live in Metropolitan Area (CAPITAL Study)].

Objectives　The aim of this research is to classify elderly adults who live alone by their marital status type and to clarify how those types affect their higher-level functional capacity and mental health with a 2-year follow-up survey.Methods　This research is based on the results from a survey in 2013. The base-line scores were from 757 participants who completed a survey by mail, carried out in B area of A ward, Tokyo, within the jurisdiction of community general support centers, with people who were not at nursing care levels 4 or 5 and who were not residents of welfare facilities. This study analyzed data for 517 of 527 participants, who answered all questions in the 2015 survey and indicated their marital status. This research categorized the respondents into 4 types of marital status: separation, divorce, bereavement, and unmarried groups. This study adopted the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) as the index of higher-level functional capacity, and the WHO-Five Well-Being Index (WHO-5-J) as the mental health index. In the analysis of the causes of 2-year variations in TMIG-IC total scores and WHO-5-J scores, the dependent variable was each variation. This study used an analysis of covariance in which the fixed factors were types of living alone, sex, annual income, and having children who lived separately in the 2013 survey, and the covariance comprised the base-line scores for the dependent variables, age, and chronic diseases in the 2013 survey.Results　With regards to the variation in TMIG-IC total scores, main effects of the types of living alone were observed. The adjusted variation of covariance decreased most in the separation group (-0.95). For the variation in WHO-5-J scores, main effects of the types of living alone were indicated. In the divorce group, the adjusted variation of covariance was significantly higher than for the unmarried group (2.33 vs. -0.55).Conclusion　The results revealed that the types of marital status: separated, divorced, bereaved, and unmarried, affect changes in the higher-level functional capacity and mental health status of elderly adults living alone, 2 years later. Thus, although previously regarded as a single category, types of marital status should be considered in the analysis of elderly adults who live alone.
