Psychological well-being of mothers of youth with fragile X syndrome: syndrome specificity and within-syndrome variability.
Fragile X syndrome, with or without autism, pushes maternal stress into child-future and family-conflict zones more than Down syndrome, so target those specific worries in support plans.
01Research in Context
What this study did
Researchers compared moms of teens with fragile X, Down syndrome, or fragile X plus autism.
They used surveys to ask about child behavior, family stress, and mom’s own mood.
The design was quasi-experimental: three existing groups, no random assignment.
What they found
Fragile X moms reported more worry about the child’s future and more family conflict than Down moms.
When autism was also present, moms felt less close to their child but did not show worse general mental health.
Overall, fragile X raised child- and family-focused stress, while autism added relationship strain.
How this fits with other research
McCarthy et al. (2006) found the same year that marital satisfaction predicted mom stress in fragile X, matching the family-conflict theme here.
Lanfranchi et al. (2012) later replicated the FXS > Down stress gap and added Prader-Willi families, showing the pattern holds across syndromes.
Raspa et al. (2014) extended the picture: fragile X families can still report high quality of life when strong social supports are present, giving a buffer strategy for the stress found in the 2006 paper.
Eapen et al. (2024) tracked moms longitudinally and showed child behavior problems lead to later maternal depression only when moms also show executive dysfunction, explaining why some fragile X moms stay resilient.
Why it matters
You can’t treat the child without supporting the parent. Screen fragile X moms for worries about the future and family conflict at intake. Offer marital or family counseling, link to fragile X parent groups, and teach problem-focused coping. These low-cost steps can lower stress before it snowballs into depression.

03Original abstract
BACKGROUND: Research on parental well-being has focused largely on Down syndrome and autism; however, fragile X syndrome is likely to pose different challenges for parents compared with these other diagnostic conditions. Moreover, there is considerable variability among youth with fragile X syndrome; for example, 25% to 33% of affected youth meet criteria for a co-morbid diagnosis of autism. It is likely that parents of youth with fragile X syndrome will experience different degrees and patterns of stress, depending on whether their offspring do or do not have a co-morbid diagnosis of autism. In the present study, we compared mothers of three groups of young males on measures of psychological well-being and stress: those with fragile X syndrome and a co-morbid diagnosis of autism; those with fragile X syndrome alone; and those with Down syndrome. METHOD: The sample consisted of mothers of adolescent and young adult males with fragile X syndrome and co-morbid autism (n=9), fragile X syndrome alone (n=19), and Down syndrome (n=19). We screened all youth for autism using the Autism Behavior Checklist, which was completed by mothers, fathers and teachers, and the youth who scored above the suggested cut-off were evaluated by a licensed psychologist to determine autism status. The three groups of youth did not differ in chronological age (16.4, 15.8 and 16.0 years, respectively) or non-verbal mental age (3.8, 3.9 and 3.8 years, respectively). Several self-report measures were completed by mothers. These measures assessed current mental health status (e.g. the Center for Epidemiological Studies Depression Scale), perceptions of their son's and family's functioning (e.g. the Positive Affect Index, which measures closeness felt by the mother to her son and also reciprocated closeness felt by the son towards the mother, as perceived by the mother), and approach to coping with their son's disability [e.g. the Multidimensional Coping Inventory (COPE), which measures emotion-focused and problem-solving focused coping]. RESULTS: The results suggest that fragile X syndrome creates more challenges to maternal psychological well-being than Down syndrome, and that the combination of fragile X syndrome and autism can be particularly challenging. Differences among groups, however, were manifested mainly as concerns about the affected son and about relationships within the family rather than as lower levels of mental health. Thus, mothers of sons with fragile X syndrome, regardless of the son's autism status, reported more pessimism about the son's future and more conflict within the family than mothers of sons with Down syndrome. Additionally, mothers of sons with fragile X syndrome and co-morbid autism reported lower levels of reciprocated closeness than the other two groups of mothers. CONCLUSION: We consider possible causes of these maternal differences, the implications for clinical practice, needs for future research, and the importance of understanding child and contextual factors as well as the dynamics leading to these differences.
