This study identified trajectories of depressive symptoms among mothers of children with or without intellectual disability longitudinally across eight time points. Results of fitting a linear growth model to the data from child ages 3-9 indicated that child behavior problems, negative financial impact, and low dispositional optimism all significantly related to initial maternal depressive symptoms. Child behavior problems were significantly associated with changes in depressive symptoms over time, relating above and beyond child disability status. When looking from late childhood into early adolescence, hierarchical linear regression analysis revealed that maternal depressive symptoms at child age 9 and perceived financial impact significantly related to maternal depressive symptoms at child age 13. Implications for practice and future research directions are discussed. [This research was conducted in collaboration with Dr. Elizabeth Laugeson and The Help Group-UCLA Autism Research Alliance.]
