Purpose
The purpose of this study was to investigate the roles of the perception of aging symptoms in mediating and moderating the relationship between family function and stress in middle-aged adults.
Methods
This was a cross-sectional correlational study of 244 middle-aged men and women. Self-administered surveys were conducted using the Family APGAR, stress index, and symptom management beliefs questionnaire. The data were analyzed using descriptive statistics, independent t-test, Pearson’s correlation coefficient, hierarchical multiple regression analysis, and PROCESS macro using SPSS 23.0.
Results
A significant interaction between family function and the perception of aging symptoms in predicting stress was found, indicating a moderating effect of the perception of aging symptoms on the relationship between family function and stress. An indirect effect of family function on stress through the perception of aging symptoms was not significant, indicating an insignificant mediating effect of the perception of aging symptoms.
Conclusion
The relationship between family function and stress differed depending on participants’ perceptions of aging symptoms. Individuals with negative perceptions of aging symptoms may be vulnerable to stress caused by poorer family function. It is necessary to develop programs to help modify negative perceptions of aging as well as strengthen family function to decrease the stress of middle-aged adults.
