The current study aims to examine the contribution of personal resources such as selfesteem, and interpersonal resources such as emotional and instrumental support, perception of the grandparenting role, and the emotions shame and guilt, to stress and well-being among mothers, and well-being and personal growth among grandmothers. As these are subjective variables, and as mothers and grandmothers are likely to have different perspectives on these issues while reciprocally affecting one another, we examined differences between mothers and grandmothers. Additionally, the reciprocal contribution of mother and grandmother variables on mental health was examined, as were the contribution of the grandmother’s variables on maternal mental health and vice versa. To identify the unique characteristics of mothers and grandmothers of children with intellectual disabilities, these groups were compared with mothers and grandmothers of typically developed children. The study sample was composed of 100 Arab mothers of children with disabilities (aged 3-14), 96 Arab mothers of typically developed children, 101 Arab grandmothers of children with disabilities, and 100 Arab grandmothers of typically developed children. Mothers and grandmothers of children with disabilities were identified through local social v services and Akim frameworks, while the comparison group participants were identified as residing in the same areas as mothers and grandmothers from the research group
