Mental ill-health in mothers of people with intellectual disabilities compared with mothers of typically developing people: a systematic review and meta-analysis.
Across 32 studies, mothers of people with intellectual disabilities show consistently higher anxiety, depression and parenting stress—screen and support these caregivers proactively.
01Research in Context
What this study did
Adams et al. (2021) pulled together 32 studies that compared mental health in two groups of moms. One group was raising a child or adult with intellectual disability. The other group was raising typically developing kids.
The team looked for signs of anxiety, depression, stress, and emotional burden. They ran a meta-analysis to see how big the gap was between the two groups.
What they found
Mothers of people with ID scored higher on every mental-health measure. More anxiety. More depression. More stress. The pattern held across all 32 studies.
The authors warn the numbers vary a lot from study to study, so they treat the results with caution. Still, the trend is clear: these moms carry a heavier emotional load.
How this fits with other research
Fairthorne et al. (2016) saw the same problem from a different angle. They tracked hospital records and found moms of kids with ASD or ID landed in psychiatric wards more often after birth. Adams et al. (2021) now shows the wider picture: the issue is not just hospital stays—it is everyday anxiety and depression.
Chou et al. (2010) zoomed in on older carers. Two-thirds reported high depressive symptoms. The new meta-analysis says the risk starts earlier and lasts throughout the lifespan.
Reeve et al. (2016) added a twist: when the adult with ID also has mental-health or behavior problems, carer stress jumps even higher. Adams et al. (2021) confirms that extra diagnoses magnify the burden, but shows the baseline risk is already elevated for any mom raising a child with ID.
Why it matters
You already track client progress. Start tracking mom’s mood too. Add two quick questions about sleep and worry to every parent meeting. If scores creep up, offer a referral or a short break. Small moves early can prevent big crises later.

03Original abstract
BACKGROUND: Mothers of people with intellectual disabilities (IDs) face exceptional challenges and may be more prone to experiencing mental ill-health compared with mothers of typically developing people. These mental ill-health problems may differ at different stages of the caregiving trajectory. However, there is no evidence synthesis on this topic. We aimed to systematically review evidence in this area and identify gaps in the existing literature. METHOD: Prospero registration: CRD42018088197. Medline, Embase, CINAHL and PsycINFO databases were searched. No time limits were applied. Studies were limited to English language. Inclusion criteria were studies of mothers of people with IDs that also included a comparison group of mothers of typically developing/developed children. Data were extracted from selected studies using a structured database. Study selection and quality appraisal were double rated. Where possible, meta-analyses were performed. RESULTS: Of the retrieved articles, 32/3089 were included, of which 10 reported on anxiety, 21 on depression and 23 on other indicators of mental ill-health. Overall, previous studies reported that mothers of people with IDs experienced poorer mental health as compared with mothers of typically developing people. Meta-analyses revealed significant findings for anxiety, depression, parenting stress, emotional burden and common mental disorders, but not for somatic symptoms. However, there was a considerable heterogeneity; hence, interpretation of results should be cautious. Identified gaps included scarce research on mental ill-health of mothers of adults with IDs at different stages of the caregiving trajectory. CONCLUSIONS: There is evidence of poorer mental ill-health in mothers of people with IDs compared with mothers of typically developing people, but lack of focus on different stages of the caregiving trajectory, methodological inconsistencies between studies and lack of robust studies pose limitations. This highlights the need both for improved support for mothers of people with IDs and for further methodologically robust research.
