ABSTRACT
PURPOSE: The purpose of this study was to identify the influencing factors on mental health related quality of life (MHRQoL) in adults across the lifespan. METHODS: A total of 688 Korean adults aged 19 years and older were selected. Data were collected by personal interviews or self report using structured questionnaires. For data analysis, t-test, ANOVA, Pearson's correlation coefficients and Stepwise multiple regression were used. RESULTS: Mental health related quality of life (MHRQoL) differed significantly according to life cycle, especially showing a lower score in the elderly than others. In addition, elderly adulthood reported the highest stress and depression. The most significant predictors of MHRQoL in young and middle aged people were stress, depression, and subjective health status. Predictors of MHQoL in the elderly were stress and religion. CONCLUSION: The results indicate that MHRQoL of adult is associated with stress and depression. When the programs are developed to enhance mental health in elderly adulthood, religion should be considered as well as stress.
