Refinements of Functional Communication Training for Aggression and Self-injurious Behavior

This study is looking at ways to improve Functional Communication Training (FCT), a common treatment for problem behaviors like aggression and self-injury in children. FCT teaches children to ask for what they want instead of acting out. Sometimes, these problem behaviors can return if the FCT is implemented differently or in new places. This study will test three approaches: Trad FCT, Mult FCT, and Mult FCT + Stimulus Fading. The goal is to see if using treatment signals (like colored cards) and gradually introducing natural items into the treatment setting can prevent problem behaviors from coming back. We are looking for 24 children, ages 3 to 17, who have destructive behaviors that occur at least 10 times a day and are reinforced by social attention. The study will measure how often destructive behaviors occur after treatment.

Eligibility criteria

Inclusion

Boys and girls from ages 3 to 17
Destructive behavior that occurs at least 10 times a day despite previous treatment
Destructive behavior reinforced by social consequences like attention (FCT is not appropriate for automatically reinforced destructive behavior)
On a stable psychoactive drug regimen for at least 10 half-lives per drug or drug free
Stable educational plan and placement with no anticipated changes during the child's treatment
Patients currently receiving 15 or more hours per week of treatment for their destructive behavior
DSM-5 diagnosis of Rett syndrome or other degenerative conditions (e.g., inborn error of metabolism)
A comorbid health condition or major mental disorder that would interfere with study participation
Occurrence of SIB during study assessments that presents a risk of serious or permanent harm (e.g., detached retinas) based on our routine clinical-risk assessment
  • Rate of Destructive Behavior in Renewal TestThrough study completion, an average of 3 weeks.

    The investigators will measure the rate of destructive behavior following successful treatment when the FCT is implemented in a context not associated with treatment (e.g., the baseline, home-like context).

  • Rate of Destructive Behavior in Super-Resurgence TestThrough study completion, an average of 3 weeks.

    The investigators will measure the rate of destructive behavior when FCT is implemented in a context not associated with treatment (e.g., a classroom context) by an implementer who fails to reinforce the communication response. This would be similar to a busy teacher in a classroom who is unable to attend to the child due to assisting another student.

  • Rate of Destructive Behavior in Reinstatement TestThrough study completion, an average of 3 weeks.

    The investigators will measure the rate of destructive behavior when FCT is not implemented as prescribed (i.e., reinforcement is delivered on a time-based schedule, rather than following communication responses). This would be similar to a teacher who delivers breaks from work based on the school schedule (e.g., switching from math to reading) rather than the child's request for a break during the math period).
