Health-promoting behaviors have been shown to enhance the quality of life across diverse populations. In this study, we examined the indirect effects of several health-promoting behaviors on the relationship between parenting stress and health-related quality of life in mothers of children with cerebral palsy (CP). A convenience sample of Korean mothers (N = 180) of children aged 10 months to 12 years with CP was recruited from clinical and school settings. Health-promoting behaviors were measured using the health-promoting lifestyle profile II, which is comprised of six subscales: health responsibility, physical activity, nutrition, spiritual growth, interpersonal relations, and stress management. Multiple mediation analyses were conducted to examine the mediating role of these behavioral categories. Spiritual growth (β = .56, p < .05) had an indirect effect on the relationship between parenting stress and physical health-related quality of life while spiritual growth (β = -1.00, p < .01) and stress management (β = -.80, p < .05) were found to mediate the association between parenting stress and mental health-related quality of life. The findings of multiple mediation analyses provide evidence of the influence of specific health-promoting behaviors on health-related quality of life, thereby informing the development of intervention programs for mothers of children with disabilities.
