Prior depressive symptoms and persistent child problem behaviours predict future depression in parents of children with developmental disabilities: The growing up in Ireland cohort study.
When a parent of a child with developmental delays is already depressed and behaviors stay tough, expect depression to linger—so screen again soon.
01Research in Context
What this study did
Gallagher et al. (2018) tracked parents of children with developmental delays over several years. They asked: if a parent is already depressed and the child’s tough behaviors stick around, will the parent still be depressed later?
The team used the Growing Up in Ireland data set. They compared parents of kids with delays to parents of typically developing kids.
What they found
Parents of children with delays showed higher depression rates, and the gap stayed wide year after year.
Two red flags stood out: a parent who was depressed at the start and a child whose problem behaviors did not improve. When both were present, later depression was very likely.
How this fits with other research
Kellett et al. (2015) used the same Irish cohort and found child behavior problems also forecast parent obesity, not just mood. Together the papers show child behaviors wear on both mind and body.
Baker et al. (2005) first linked child behaviors to lower maternal well-being, but only at one time point. The 2018 study proves the risk lasts for years.
Tan et al. (2026) flip the lens: when parents struggle to regulate their own emotions, autistic children later show more problem behaviors. The two studies sketch a feedback loop—child behaviors fuel parent depression, and parent negativity fuels child behaviors.
Why it matters
You already watch for skill gains; now watch for parent mood too. If intake notes show prior depression and the child’s behaviors are still high, schedule a quick depression screen at every visit. A two-minute checklist can catch a slide early and open the door to supports that help both parent and child stick with treatment.

03Original abstract
Predictors of depression over time were examined in parental carers of children with developmental disabilities (DD) and parents of typically developing children (controls) who participated in the Growing up in Ireland Study. Parents completed measures of depression, the Centre for Epidemiological Depression Scale (CES-D) and child problem behaviours, the Strength and Difficulties Questionnaire when the children were aged 9 (Wave 1) and 13 (Wave 2). Using CES-D cut-off scores to indicate probable depression, caregivers were more likely to be depressed at both waves compared to controls with a Wave 1 rate of depression of 14.6% vs. 7.9% (p < 0.001, Cramer`s V = 0.059) and Wave 2 (14.8% vs. 10%, p = 0.003, Cramer`s V = 0.038). While overall rates of depression were stable for caregivers, a shifting pattern emerged; 59.6% of those who were depressed at Wave 1, were not at Wave 2; similarly, 10.9% who were not depressed at Wave 1, were at Wave 2. Parents of children with DD were also more likely to report greater problem behaviours in their children compared to controls at both waves. Depression in caregivers at Wave 1 and persistent child problem behaviours were significant predictors of depression at Wave 2. In conclusion, while overall rates of depression remain stable in caregivers, there are shifting patterns evident with prior depression and persistent behaviour problems predictive of ongoing depression.
