Detailed Description
Elopement (running/wandering away from supervision) affects nearly 50% of children with ASD and is a contributor to the fact that children with ASD have nearly double the premature death rate of their typically developing peers. Existing interventions, such as prevention kits, increase safety by decreasing elopement opportunities (e.g., locking doors), but do not necessarily decrease attempts. Given that a single successful attempt can be fatal, the fact that prevention-only strategies cannot eliminate elopement means that other treatment approaches are necessary. Interventions based in applied behavior analysis (ABA) have been successful in reducing elopement attempts. ABA relies on function-based treatments, which start with assessment to identify why an individual elopes (i.e., its function). Common functions of elopement include accessing attention (e.g., parent's reaction), preferred items (e.g., toys), or escape from nonpreferred situations (e.g., leaving a store). Function is crucial, as common strategies may be contraindicated based on function. For example, a caregiver may pick up a child and discuss safety after elopement. Unfortunately, this may reinforce elopement, and make it worse, if the function for that child is to gain attention. Key elements of function-based treatments include preventing delivery of the functional reinforcer following elopement (i.e., extinction) and teaching an appropriate means of accessing it instead.
While there is support in the literature for function-based treatments, it has relied on small sample sizes. In the largest elopement treatment study to date, the researchers demonstrated significant improvements based on clinical outcomes. However, even this study was relatively small (N=11) and lacked a control group. The bulk of research supporting these interventions has also been conducted in specialized treatment centers by doctoral level professionals. This is in contrast to the majority of ABA services delivered by Master level Board Certified Behavior Analysts (BCBAs) operating in community settings. Thus, even if ABA-based interventions are efficacious, their generality and community viability remain unknown. Finally, research has evaluated either prevention strategies or function-based interventions, while studies combining these are strikingly absent.
A randomized controlled trial designed to test the efficacy of a structured, exportable intervention for elopement with prevention strategies and function-based interventions has not been conducted, but is critical for several reasons. First, rigorous studies with a control group and sufficient sample size are needed for function-based treatments to be widely accepted as empirically supported. Second, evaluation of a manualized intervention combining these approaches implemented in a community context will demonstrate the viability outside of specialized clinics. A manualized treatment can serve as a much needed resource for community providers faced with treating elopement. The researchers have developed a manualized, parent-mediated intervention called Function-Based Elopement Treatment (FBET). In a pilot feasibility study the researchers evaluated FBET with 24 children with ASD (age 4 to 12), who were randomly assigned to FBET (n=12) or a waitlist (n=12).
In this study, participants will be randomized to receive the FBET intervention or PEP for 16 weeks. Participants in the PEP study arm will be offered the opportunity to have the FBET intervention at the end of the 16 week study period. The study aims are to:
Aim 1: Evaluate whether FBET is superior to PEP in reducing elopement in 76 children (age ≥ 4 to ≤ 12) with ASD after 16 weeks of treatment using the Aberrant Behavior Checklist-Hyperactivity subscale (ABC-H).
Aim 2: Evaluate two key secondary outcomes (at Wk 16): a) the independent evaluator ratings on the Clinical Global Impression-Improvement rating (CGI-I) and b) home safety, based on the percentage of prevention items endorsed on the home elopement safety checklist (HESC).
Aim 3: Evaluate whether direct observation of elopement, based on parent data on elopement frequency for one week leading up to each assessment point, demonstrates a significant decrease in the FBET compared to PEP participants.
Aim 4: Evaluate whether gains made in the FBET group are maintained after treatment (at Wk 28, using the ABC-H, HESC, and CGI-I)
Exploratory Aim 1: To evaluate the impact of FBET on disruptive behavior using the ABC-Irritability subscale

Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Function-Based Elopement Treatment (FBET)
Participants in this group will receive Function-Based Elopement Treatment (FBET) for 16 weeks.
|
The Function-Based Elopement Treatment (FBET) includes 12 appointments over 16 weeks. FBET focuses on parent-training, with the parent implementing procedures with therapist support. The goals of FBET are:
|
Active Comparator: Parent Education Program (PEP)
Participants in this group will take part in a parent education program (PEP) for 16 weeks.
|
The Parent Education Program (PEP) will include 12 appointments over 16 weeks, focused on general education about autism spectrum disorder and resources about elopement prevention.
PEP will be administered by a Board Certified Behavior Analyst (BCBA).
Participants randomized to the PEP study arm can receive the FBET intervention after completing the 16 week study period.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Aberrant Behavior Checklist - Hyperactivity (ABC-H) Subscale Score
Time Frame: Baseline, Week 16
|
Elopement will be measured by the hyperactivity subscale of the Aberrant Behavior Checklist (ABC-H).
The full ABC is a 58-item caregiver completed measure with 5 subscales.
It is used extensively with children with ASD in clinical trials and has demonstrated validity and reliability with this population.
Although the ABC-H targets hyperactivity, there are several items directly related to elopement.
The hyperactivity subscale includes 16 items that are answered on a scale of 0 (not a problem) to 3 (severe problem).
Scores for this subscale range from 0 to 48, where higher scores indicate a higher severity of hyperactivity.

Baseline, Week 16
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Clinical Global Impression - Improvement (CGI-I) Score
Time Frame: Week 16
|
CGI-I asks an independent evaluator to rate the degree of improvement, compared to the last visit, on a scale of 1 (very much improved) through 4 (no change) to 7 (very much worse).
|
Week 16
|
Change in Home Elopement Safety Checklist (HESC) Score
Time Frame: Baseline, Week 16
|
The Home Elopement Safety Checklist (HESC) is a 22-item instrument listing steps to prevent elopement (e.g., locks, alarms) and decrease safety risk if elopement were to occur (e.g., purchasing identification bracelets).
Parents indicate if each item has been completed or not and the percentage of completed items is the total safety score.
The a higher percentage means that more safety elements have been implemented in order to reduce elopement or to increase the child's safety if they do elope.
|
Baseline, Week 16
|
Direct observation of elopement frequency
Time Frame: Baseline, Week 16
|
The frequency of elopement will be assessed based on parent data on elopement frequency for one week leading up to each assessment point.
|
Baseline, Week 16
|
Change in Aberrant Behavior Checklist - Hyperactivity (ABC-H) Subscale Score
Time Frame: Week 16, Week 28
|
To evaluate whether gains made in the FBET group are maintained after treatment, the ABC-H will be repeated at the Week 28 follow up visit.
Elopement will be measured by the hyperactivity subscale of the Aberrant Behavior Checklist (ABC-H).
The full ABC is a 58-item caregiver completed measure with 5 subscales.
