Loneliness and its correlation with self-care and activities of daily living among older adults: a partial least squares model.

Background: The growing elderly population worldwide is accompanied by an increased disrupting daily activities and self-care. Neglecting the multifaceted needs of the elderly can lead to detrimental effects such as loneliness or social isolation, threatening healthy aging. Self-care is a key strategy to enhance daily functioning and mitigate feelings of loneliness among the elderly. This study was conducted with the aim of investigating the feelings of loneliness and its relationship with self-care and Activities of Daily Living (ADL) among the older adults of Tabriz city.

Methods: In this observational cross-sectional study, we engaged 315 older adults using a simple random sampling. Participants were selected randomly from Iran's Integrated Health System (IIHS) framework. Three questionnaires including de Jong Gierveld Loneliness Scale, Persian version of self-care scale, and ADL-Katz were used for data collection. The Partial Least Squares and Spearman's correlation were used to investigate the relationships between demographic characteristics, loneliness, self-care, and ADL.

Results: The sample comprised 315 respondents 51.1% were female, 49.5% had a middle school literacy and 86% were married. A significant negative relationship was observed between loneliness and self-care (P < 0.001 and r =-0.311). Demographic characteristics, including age and marital status, were found to negatively moderate the relationship between self-care (path coefficient - 0.07, P = 0.044) and positively moderate the relationship with loneliness (path coefficient 0.29, p < 0.001). ADL was positively associated with self-care (path coefficient 0.41, p = 0.046) and also a direct and significant relationship was observed between ADL and daily self-care (P < 0.001 and r = 0.335).

Conclusion: This study underscores the complex interplay between loneliness, self-care, and ADL. It highlights the need for interventions that address emotional health and daily living skills as part of comprehensive self-care strategies. Further research is needed to explore these relationships in more detail and to develop targeted interventions for different demographic groups.
