What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at a common problem in behavior therapy for children with severe aggression or self-injury: sometimes, when therapists stop rewarding problem behaviors (called extinction), the child's behavior briefly gets worse before improving. This 'extinction burst' can be dangerous. Researchers will test 40 children aged 3-17 to see how often this happens and whether changing how rewards are given can reduce the risk. The goal is to make therapy safer and more predictable.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
behavioral intervention (extinction-based therapy)
What this could lead to
If successful, this could help therapists predict and reduce the temporary increase in problem behavior that sometimes occurs when starting treatment, making therapy safer and more effective.
What could go wrong
This is a small, early-stage study with only 40 children, so findings may not apply to everyone. The research focuses on understanding a side effect, not on testing a new cure or treatment.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 40 people

The number the study aims to enrol. It can still change while the study runs.

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. children aged 3 to 17; 2. problem behavior that occurs at least 10 times a day, despite previous treatment; 3. problem behavior maintained by social positive reinforcement; 4. stable protective supports for self-injurious behavior (e.g., helmet) with no anticipated changes during enrollment; 5. on a stable psychoactive drug regimen for at least 10 half-lives per drug or drug free; 6. stable educational plan and placement with no anticipated changes during the child's treatment. Exclusion Criteria: 1. patients currently receiving 15 or more hours per week of treatment for their problem behavior; 2. DSM-5 diagnosis of Rett syndrome or other degenerative conditions (e.g., inborn error of metabolism); 3. a comorbid health condition or major mental disorder that would interfere with study participation; 4. occurrence of self-injury during study assessments that presents a risk of serious or permanent harm (e.g., detached retinas) based on our routine clinical-risk assessment; 5. patients requiring changes to protective supports for self-injury or drug treatment, but we will invite these patients to participate when protective supports and drug regimen are stable.
