Examining the Links Between Received Network Support and Marital Quality Among Mothers of Children with ASD: A Longitudinal Mediation Analysis

Employing a cohort sequential design and multilevel modeling, the direct and indirect effects (via depressed mood, emotional wellbeing, and perceived support) of received network support on marital quality were assessed over a 7-year period (child age 7-14) on 96 married or cohabiting mothers of children with ASD. Findings indicated several significant direct and indirect effects affecting change within mothers over time, with effects varying by whether the support source was a spouse or partner, family members, or friends. In addition, one moderated mediation effect was noted, with the indirect effect of received spousal support on marital quality via perceived spousal support retaining significance only at low and moderate levels of child problem behavior severity. Study strengths, limitations, and clinical implications are discussed.
