Structural equation model of the relationship between functional ability, mental health, and quality of life in older adults living alone.

AIMS: Living alone, a reality in an increasing number of older adults recently, is a risk factor for low quality of life. This study identified the predictors of quality of life in older adults living alone based on mental health and the International Classification of Functioning, Disability, and Health. METHODS: This secondary data analysis used information from the 2018 Assessing the Requirements of Customized Health Care and Daily Living Support Services survey (N = 1,022), collected from adults aged ≥ 65 living alone in Siheung City, South Korea, from August to October 2018. The exogenous variables were body functions (hand grip strength, timed "up and go" test score, and body mass index), daily living activities (Korean Instrumental Activities of the Daily Living Scale), social activity participation (social activity engagement, neighbor contacts, and family contacts), and participation in economic activity (frequency). The endogenous variables were mental health (Geriatric Depression Scale Short Form-Korean Version and UCLA Loneliness Scale) and quality of life (EuroQoL-5 Dimension-3 Level and EuroQoL-Visual Analog Scale). RESULTS: After modifying the hypothetical model, which had failed to satisfy the recommended fitness level, the (modified) model had good fitness indices Q (CMIN / df) 2.90, GFI 1, AGFI 1, RMSEA 0.04, CFI 0.90 and PCFI 0.53. Of the nine pathways of the modified model, five were statistically significant. Quality of life was affected by body functions, daily living activities, social activity participation, and mental health. These variables explained 68.2% of the factors affecting quality of life. CONCLUSIONS: By highlighting the role of mental health, this model provides a useful framework for improving the quality of life of older adults who live alone and function at various levels in the community. Focusing on advancing mental health through body functions, daily living activities, and social activity participation can improve quality of life.

The relationship between communication competence and exercise participation type: focusing on joining clubs and using fitness applications.

The purpose of this study was to determine the effects of the differences in subfactors of communication competence on exercise participation types (clubs, applications use). Communication competence focus on the communication part of the individual's interpersonal competence. Therefore, communication competence can be predicted to be related to the type of exercise participation. Accordingly, the targets of this study were clubs, which had group characteristics, and fitness applications, which had individual characteristics. There was a significant difference as a result of the association between communication competence and the type of exercise participation. In terms of club membership, significant differences were found in communication competence skills according to exercise participation types in that self-disclosure of subjects who joined clubs was significant, social relaxation of subjects who intend to join a club was significant, and the immediacy of fitness applications users was significant.
