Examining the function of problem behavior in fragile X syndrome: preliminary experimental analysis

Area of Science:

• Neurodevelopmental Disorders
• Behavioral Psychology
• Genetics

Background:

• Fragile X syndrome (FXS) is the leading inherited cause of intellectual and developmental disabilities.
• Environmental influences on FXS-associated behaviors are understudied.
• Problem behaviors in FXS may serve specific functions that require investigation.

Purpose of the Study:

• To explore the functional role of problem behavior in children with Fragile X syndrome.
• To identify the environmental variables that maintain problem behaviors in this population.

Main Methods:

• Employed experimental functional analysis methodology.
• Assessed 8 children diagnosed with Fragile X syndrome.
• Categorized problem behavior based on maintaining consequences (attention, escape, tangible).

Main Results:

• No participants exhibited attention-maintained problem behavior.
• Five participants displayed escape-maintained problem behavior.
• Four participants demonstrated tangible-maintained problem behavior.

Conclusions:

• Problem behaviors in Fragile X syndrome are primarily maintained by escape and tangible reinforcement.
• Findings suggest specific targets for intervention development.
• The small sample size limits the generalizability of these results.
