Autism spectrum disorders (ASD) are neurodevelopmental disorders characterized by difficulties in communication and social-emotional interaction. It is associated with an increase of parental stress and poor family functioning, both of which are harmful for a child’s functioning and adaptive behavior. An important source of support to parents are grandparents, especially in traditional populations. One such population is the Bedouin population. The present study tested the association between emotional support from mother and mother-in-law to the adaptive behavior of children with ASD, and whether this relation is serially mediated by family functioning and satisfaction in life as reported by Bedouin mothers of children with ASD. 100 mothers of children with ASD fulfilled a questionnaire about emotional support from their mothers and mother-in-law, family functioning, satisfaction in life and child’s adaptive behavior. We found that indeed, family functioning and satisfaction in life serially mediated the relations between emotional support from mother and mother-in-law and child adaptive behavior. These findings indicate that intergenerational solidarity between women can improve not only the functioning of the nuclear family and wife’s satisfaction with life, but also, indirectly, the adaptive behavior of a child with ASD. It highlights the importance of women solidarity, especially in traditional society, where women are kept marginal.
