Service Delivery

From Concerns to Care: Understanding Parental Priorities and Access to Early Intervention for Infants With Fragile X Syndrome.

Scott et al. (2026) · Journal of intellectual disability research : JIDR 2026
★ The Verdict

Even with a gene diagnosis, half of FXS babies miss early intervention by one year unless you push the referral through.

✓ Read this if BCBAs in early-intervention or pediatric clinics who see babies with genetic diagnoses.
✗ Skip if Practitioners serving only school-age children with no intake role.

01Research in Context

01

What this study did

The team asked families how they got early-help services for babies with fragile X.

They mixed surveys and interviews. All infants had a gene test proving FXS.

Parents told their stories from diagnosis day until the first birthday.

02

What they found

Only half of the babies were in Part C by age one.

Families noticed motor delays first, then speech delays.

Occupational therapy was the service most families used.

03

How this fits with other research

Pitchford et al. (2019) show parent coaching can work for FXS toddlers, yet Samantha et al. reveal most families never reach those programs.

Capio et al. (2013) urged newborn FXS screening so infants could start therapy early. Samantha et al. prove the screening is only step one; the referral bridge still breaks.

Finucane et al. (2013) found autism clinicians rarely ask about FXS. The new data explain why: low provider knowledge keeps the Part C door closed.

04

Why it matters

You can close the gap. When an infant tests positive for FXS, write the Part C referral the same day. Track if services start within 30 days. If they do not, call the service coordinator yourself. One extra phone call can move a baby from the 50 % who wait to the 50 % who get help.

03Original abstract

BACKGROUND: This study examined the experiences of infants diagnosed with fragile X syndrome (FXS) in the newborn period and their caregivers during the infant's first year of life. The primary objective was to understand caregiver concerns and access to early intervention services for infants diagnosed with FXS presymptomatically. METHODS: Participants for this study were part of a pilot intervention programme for newborns with FXS and their caregivers. A mixed-methods approach was taken combining data from caregiver questionnaires as well as intervention session notes to identify caregiver concerns and early intervention services. RESULTS: Caregivers of infants with FXS consistently reported concerns in motor development in the first few months of life with increasing concern regarding communication development closer to 12 months of age. Despite all being eligible based on having an established condition and instruction for accessing early intervention services provided by the intervention team, only half of participants were enrolled in their state's Part C programme by the child's first birthday. Occupational therapy was the most accessed service (33% of infants), followed by physical therapy (27%), feeding therapy (20%), speech therapy (13%) and developmental play therapy (7%). CONCLUSIONS: Although one of the main benefits of earlier diagnosis is purported to be earlier access to interventions, we found infants diagnosed with FXS prior to emergence of symptoms experienced barriers to accessing early intervention services, despite FXS being an established condition for Part C services. These findings highlight the need for further exploration of the referral process for infants diagnosed with neurogenetic conditions in infancy.
