The moderating effect of religiosity on caregiving burden and depressive symptoms in caregivers of patients with dementia.

OBJECTIVES: This study explored whether religiosity/spirituality has a protective role against negative caregiving outcomes, in a large multicenter nationwide sample of caregivers of patients with dementia in South Korea. Additionally, this study was the first to examine whether religiosity/spirituality could affect caregiving outcomes according to the various religious affiliations of caregivers. METHODS: The study was conducted on a sample of 476 caregivers of patients with dementia participated in the Clinical Research Center for Dementia of South Korea (CREDOS). We examined the moderating effect of each of the three dimensions of religiosity/spirituality (organizational religious activity, ORA; non-organizational religious activity, NORA; intrinsic religiosity, IR) on the relationship between activities of daily living (ADL) of patients with dementia and caregiving burden and depressive symptoms of caregivers, using a series of hierarchical regression analyses. In addition, these analyses were conducted according to the religious affiliations of the caregivers. RESULTS: ORA, NORA, and IR of religiosity/spirituality alleviated the effect of ADL of patients on caregiving burden. ORA and IR moderated the relationship between ADL of patients and depressive symptoms of caregivers. These moderating effects of religiosity on caregiving outcomes were different according to various religious groups. CONCLUSION: We have identified religiosity/spirituality as a protective factor for caregivers of patients with dementia. The sub-dimensions of religiosity as moderators were different by religious affiliations of caregivers. Further studies are needed to investigate the specific religiosity-related factors which could positively impact the mental health of the caregivers of patients with dementia by religions.

The relationship of the Korean version of the WHO Five Well-Being Index with depressive symptoms and quality of life in the community-dwelling elderly.

BACKGROUND: Depression in the geriatric population is becoming markedly more prevalent. Quality of life has been linked with the development of depression. A screening tool for assessing both geriatric depression and quality of life is needed. OBJECTIVE: The purpose of this study was to assess the utility of the Korean version of the World Health Organization Five Well-Being Index (WHO-5) in evaluating geriatric depression and quality of life as compared to the widely used Short Geriatric Depression Scale of Korean version (SGDS-K). METHODS: Two hundred and forty four elderly people (>60-years-of-age) living in the Yanggu and Inje areas of Gangwon Province, Korea, were interviewed and responded to scales including WHO-5, SGDS-K, Mini Mental Status Examination in the Korean version of the CERAD assessment packet (MMSE-KC), and Geriatric Quality of Life-Dementia (GQOL-D). A total WHO-5 score<13 indicated low well-being. RESULTS: The SGDS-K score showed a reverse correlation with the WHO-5, MMSE-KC, and GQOL-D scores. The WHO-5 score reversely correlated with the SGDS-K score and positively correlated with GQOL-D, but showed no significant correlation with MMSE-KC score. Subjects ranked as having poor well-being (WHO-5 score<13) had a significantly lower GQOL-D score and a significantly higher SGDS-K score. In multiple regression analysis, WHO-5 was significantly associated with GQOL-D and SGDS-K. CONCLUSION: The Korean version of WHO-5 is useful in evaluating both depressive symptoms and quality of life of community-dwelling elderly.

Association between religiosity/spirituality and quality of life or depression among living-alone elderly in a South Korean city.

INTRODUCTION: This study investigated the effects of religiosity and spirituality on quality of life and depression among older people. METHODS: Two hundred and seventy-four solitary elderly people aged over 65 years living in Chuncheon city, South Korea were selected. Symptoms of depression were evaluated using the Short Geriatric Depression Scale-Korean version (SGDS-K) and quality of life was measured using Geriatric Quality of Life-Dementia (GQOL-D). We used the Duke Religion Index (DUREL) to assess religiosity and spirituality. RESULTS: There was a significant correlation between scales of depression (SGDS-K), quality of life (GQOL-D), and scale of religiosity/spirituality (DUREL) in older people. Depressed people had a lower score GQOL-D than non-depressed people. Among the depressed, those believing in a religion had a higher GQOL-D score than the non-religious. Multiple regression analysis revealed that religiosity and spirituality had significant effects on depression and quality of life among the elderly. Interestingly, religiosity and spirituality were not related to depression and quality of life amongst Buddhists, but were related amongst Protestants and Catholics. DISCUSSION: Religiosity and spirituality had significant effects on depression and on quality of life among the Korean elderly. However, there are different relationships between depression and religiosity, quality of life, and religiosity based on different religions. More research is needed to elucidate these findings.
