# Exploring the relationship between self-care agency and quality of life in adults with diabetes: A cross-sectional study

## TL;DR

This study explores how self-care abilities in adults with diabetes relate to their quality of life, focusing on stress coping and support use.

## Contribution

Identifies specific self-care agency factors linked to mental quality of life in diabetic patients, offering targeted nursing support strategies.

## Key findings

- Ability to cope with stress is strongly linked to social/role quality of life in diabetic patients.
- Self-care agency factors like stress coping and support utilization correlate with mental quality of life across age and sex groups.
- No self-care agency factors were associated with physical quality of life in the study population.

## Abstract

Self-care agency is the ability to perform self-care. Clarifying the factors of self-care agency that are related to quality of life can help determine the most effective nursing support. This cross-sectional study of patients with type 1 or type 2 diabetes aimed to explore the relationship between self-care agency and quality of life in adults with diabetes. Using a selective sampling method, we conducted a questionnaire survey using the Instrument of Diabetes Self-Care Agency and the SF-12 Health Survey. After identifying items related to quality of life from single regression and correlation analyses, multiple regression analyses were performed. There were 139 respondents, with an average age of 62.8 ± 11.7 years, of whom 71 were men (51.0%) and 117 had type 2 diabetes (84.1%). The average self-care agency score was 153.6 ± 22.5 points. Based on the results of the single regression analysis, age, sex, HbA1c, and BMI were selected as adjustment factors. Multiple regression analyses showed that the “ability to cope with stress” was related to the role/social component summary of health-related quality of life (β = 0.40, p < 0.01). The association between self-care agency and the mental component summary differed by age and sex, while “ability to cope with stress” was commonly related to this component across all groups (β = 0.39–0.70, p < 0.05). The “ability to make the most of the support available” (β = 0.37–0.52, p < 0.05) and the “ability to self-manage” (β = 0.51–0.56, p < 0.01) were also related to this component in the 65-and-over group. No factors of self-care agency were related to the physical component summary of health-related quality of life. The results suggest that nurses can clarify the type of support that will lead to improved quality of life by evaluating patients’ self-care agency.
