Our Fragile X World collects data from families using online surveys and in-person studies. The studies cover topics such as sensory or behavioral challenges, health care experiences, and the impact of fragile X on families.

Stress, Coping, and Mindfulness in Mothers of a Child with Fragile X Syndrome

We are inviting mothers of a child with the full mutation aged 3-25, to take part in a new survey. The survey asks mothers about their stress and how they cope with it. It also asks if they have an interest in learning more about mindfulness, a way to reduce stress.

Raising a child with FX can be a joy, but it can also be a challenge. On top of this, mothers with the premutation may also be facing their own health issues. We hope to use what we learn to create a stress reduction program especially for mothers of children with fragile X syndrome.

If you are in our registry and eligible for this survey, we have emailed you a survey code. Please check your email. You will need to enter this code before you start the survey.

Fragile X Caregiver Burden Survey (2011)

In this survey, we talked to caregivers of people with fragile X. We asked them how caregiving affected their health, finances, and daily lives. We also looked at the health characteristics of children and adults with fragile X syndrome. We asked caregivers about the number of visits their child made to specialists and their child's use of medications.

National Fragile X Survey – Phase I (2008)

In 2007, we led the first national survey of families touched by fragile X syndrome. Over 1,250 families took part in the study. They answered questions about topics such as family adaptation, conditions related to fragile X syndrome, health experiences, and functional skills. This survey provided new knowledge about fragile X syndrome. It showed that parents are a valuable source of research information.
