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 Results may not be published yet.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

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 whether using a preferred communication method (like a touch talker or picture cards) helps people with intellectual or developmental disabilities maintain positive behavior changes and avoid relapse. Researchers will compare two groups: one starting with a preferred method, the other with a non-preferred method. The goal is to see which approach leads to longer-lasting improvement when treatment is disrupted.

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 (preferred vs. non-preferred communication strategies)
What this could lead to
If it works, this could point toward better ways to maintain positive behavior changes and reduce relapse in people with intellectual or developmental disabilities.
What could go wrong
This is a small, early-stage behavioral study with only 60 participants. Results may not apply to everyone, and the intervention may not work as well in real-world settings.

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 60 people

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

Started

Expected to finish

Mar 2031

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.

Ages

2 to 90 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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

Inclusion Criteria: * 2 years old and older. * Diagnosis of intellectual or developmental disability. * Referred for assessment and treatment of challenging behavior. Exclusion Criteria: * Challenging behavior does not occur within the context of structured assessment, eliminating the ability to identify its operant function, or the behavior is deemed too dangerous to safely observe during assessment. * Communicate functionally using vocal/verbal communication. * Can only identify one proficient AAC strategy.
