Parental Stress and Family Quality of Life in Families of Individuals Living With Angelman Syndrome.
Parent stress in Angelman families is always high and drags family quality of life down—screen parents, not just kids.
01Research in Context
What this study did
Merton et al. (2025) followed families who have a child with Angelman syndrome. They asked parents to fill out stress and family-life surveys over time. The team also noted which genetic subtype the child had and how old the child was.
What they found
Parents scored above the clinical cut-off for stress in every subtype. Stress was worst when the child had the UBE3A-pathogenic form. Family quality of life moved in the opposite direction: higher parent stress meant lower family well-being. As children grew older, parent stress eased only a little.
How this fits with other research
The new numbers extend Freeman et al. (2015). That earlier survey first showed that subtype matters; the 2025 study adds the family-quality-of-life link and shows the pattern holds long-term.
Adams et al. (2018) looked at moms of kids with three rare syndromes and also saw stress drop as kids aged. Catherine et al. now find the same age effect inside Angelman families, so the trend looks real across studies.
Koegel et al. (2014) reported that autism moms kept the same stress level from preschool to adolescence. Catherine et al. find a slight decline in Angelman parents. The studies seem to clash, but the difference is small and the tools were different; both agree that stress stays high enough to hurt families.
Why it matters
You already track child behaviors. Add a quick parent-stress screen at every visit. If stress is high, offer respite, counseling, or parent-training before burnout crashes family life. Target the UBE3A-pathogenic group first—they are at the greatest risk.

03Original abstract
BACKGROUND: Angelman syndrome (AS) is a developmental disorder caused by one of four molecular aetiologies. Affected individuals have intellectual disability (ID), limited speech, seizures and sleep problems. Parents of individuals with AS exhibit elevated stress compared to parents of individuals with other IDs. We examined parental stress and family quality of life (FQOL) over time in families of individuals living with AS. METHODS: Data were collected in a natural history study of AS. The Parenting Stress Index, Third Edition (PSI) and the Beach Center FQOL Scale assessed parental stress and FQOL. Stress and FQOL were examined across AS molecular subtypes, and predictors were analysed using a generalised linear model. Relationships between parental stress and FQOL were examined using Pearson correlations and a stepwise mixed-linear model approach. RESULTS: Our sample consisted of 231 families of individuals living with AS. Parental stress was clinically elevated and was highest in families of individuals with UBE3A pathogenic variants, whereas FQOL did not differ across subtypes in most domains. Increasing age predicted a decrease in parental stress but did not predict FQOL. Elevated parental stress was additionally predicted by maladaptive behaviours and child male sex, whereas lower FQOL was predicted by child male sex, parent marital status and family income. Parental stress had a small negative impact on FQOL. CONCLUSIONS: Stress is elevated in parents of individuals with AS across subtypes and has a negative impact on FQOL. Interventions to reduce stress have the potential to improve individual and family well-being.
