Background/Objectives: The purpose of this study is to identify the factors influencing the subjective wellbeing of the middle-aged class and to identify the relative influence of the variables.
Method/Statistical Analysis:The subjects of this study consisted of a middle-aged class group, aged 40 to 64, among the panels of an online research company, and data was collected from a total of 196 subjects. The collected data were analyzed using descriptive statistics, t-test, ANOVA, post-test Scheffé test, Pearson's correlation coefficient and stepwise multiple regression using SPSS 22.0.
Findings:The average score of the subjective well-being of the middle-aged class was 3.34. The difference in subjective well-being according to general characteristics was found to be significant according to education (F=4.89, p=.009) and economic status (F = 9.76, p<.001).Subject's subjective well-being was positively correlated with health status (r=.56, p<.001), meaning in life (r=.66, p<.001), generativity (r=.76, p<.001), self-efficacy (r=.62, p<.001), and social support (r=.57, p<.001). As a result of stepwise regression analysis, generativity (β=.424, p<.001), health status (β=-.209, p<.001), social support (β=.190, p=.001), and self-efficacy (β=.150, p=.014) were factors affecting subjective well-being, and the explanatory power of these 4 variables was 62.6%. The most influential variable was generativity.Improvements/Applications: This study considered variables in various fields to provide nursing intervention to promote subjective well-being of the middle-aged class, and as a result, it will contribute to promoting a qualitative life by improving the health potential of the middle-aged class.
