Conditions

Disruptive Behavior, Fragile X Syndrome

Brief summary

Disruptive behaviors such as self-injury, aggression, and property destruction pose significant health-related issues to children diagnosed with fragile X syndrome (FXS), impacting the child's quality of life and causing significant distress to families. Access to appropriate treatment for families is severely limited by factors such as cost of care, shortages of qualified treatment providers, and geographic spread of children with FXS across the country. To address these potential issues, the effectiveness of administering a standardized function-based behavioral treatment for problem behaviors in FXS will be evaluated using telemedicine. The proposed study intervention therefore offers a tremendous step forward in clinical research both in the field of FXS and in the field of developmental disabilities more broadly, and thus will have a significant impact on public health.
