The contribution of marital quality to the well-being of parents of children with developmental disabilities.

BACKGROUND This study examines the contribution of the marital relationship to the well-being of both mothers and fathers of children with developmental disabilities. Parent well-being is conceptualized in terms of mental health, parenting stress and parenting efficacy. METHODS These analyses are based on data from 67 families participating in the Early Intervention Collaborative Study, an ongoing longitudinal investigation of the development of children with disabilities and the adaptation of their families. Multidimensional assessment techniques were used to collect data from married mothers and fathers and their child with a disability. Mother and father data were analysed separately using parallel hierarchical regression models. RESULTS For both mothers and fathers, greater marital quality predicted lower parenting stress and fewer depressive symptoms above and beyond socio-economic status, child characteristics and social support. In relation to parenting efficacy, marital quality added significant unique variance for mothers but not for fathers. For fathers, greater social support predicted increased parenting efficacy. Child behaviour was also a powerful predictor of parental well-being for both mothers and fathers. CONCLUSION The findings support the importance of the marital relationship to parental well-being and illustrate the value of including fathers in studies of children with developmental disabilities.
