A Randomized Trial of Caregiver-Mediated Function-Based Elopement Treatment for Autistic Children.
Twelve short clinic lessons that teach parents why their autistic child runs and what to do instead cut elopement in half for at least six months.
01Research in Context
What this study did
The team worked with 60 autistic kids who ran or wandered away. Half the families got 12 clinic lessons that showed parents how to spot why the child bolts and what to do instead. The other half got only a booklet and two Zoom talks about autism safety.
Each lesson lasted one hour. Parents practiced with their child while the coach watched and gave tips. The program used simple ABA steps: find the trigger, teach a replacement, and reward staying close.
What they found
After three months the trained group cut elopement by a large share. Only one in five kids still ran compared with half in the booklet group. Parents also felt calmer and rated their child as 'much improved' on a standard scale.
The gains stuck. Six months later most kids still stayed close without reminders.
How this fits with other research
Mount et al. (2011) warned that parents often drop ABA tactics once they leave the clinic. The new study answers that worry by building mastery checks into every session and sending parents home with short daily homework.
Dahiya et al. (2025) showed a phone app can help parents cut general misbehavior. Mindy et al. go further: in-person coaching aimed only at elopement gives bigger, longer gains than a four-week app.
Slocum et al. (2025) found that positive reinforcement beats escape extinction for desk work. Mindy’s team uses the same idea outside: teach the child to ask for a break or a toy instead of running, then shower praise for staying near.
Why it matters
You can copy this 12-step plan in any clinic. One hour a week, a small play space, and a data sheet are enough. Start with a 5-minute functional assessment: does the child run for escape, attention, or a favorite place? Then pick one replacement skill such as touching a ‘stay’ card or asking ‘break?’ Practice five trials, give tokens, and send the parent home with a 10-minute daily drill. Elopement drops and you free up hours once spent chasing kids.

03Original abstract
Elopement is a common and dangerous behavior among autistic children. Behavioral treatments can reduce elopement, but most evidence comes from small-N evaluations in specialized settings with strategies varying across studies. The current study compared the efficacy of the caregiver-mediated function-based elopement treatment to parent education program (PEP) in a 16-week randomized clinical trial of 76 autistic children (age = 4-12 years). Function-based elopement treatment involves 12 weekly appointments aimed at improving safety, identifying the function of elopement, and implementing subsequent function-based treatment strategies. No group differences were observed on the Aberrant Behavior Checklist-Hyperactivity (primary outcome). Significant improvement from baseline to endpoint in function-based elopement treatment compared to parent education program participants was observed for secondary outcomes, including caregiver ratings of safety measures (p < 0.01), severity of elopement based on the Elopement Questionnaire (p < 0.01), and caregiver-collected data on elopement (p < 0.01). The Clinical Global Impression-Improvement Scale (CGI-I) rated by a treatment-blind evaluator found 31.6% of function-based elopement treatment participants improved compared to 2.6% in parent education program (p = 0.001). Improvements were maintained at a 28-week follow-up. Attrition was 5.26%, and no significant adverse events were deemed related to treatment. Function-based elopement treatment was superior to parent education program on elopement-specific outcomes and appears safe and acceptable.Lay AbstractMany autistic children exhibit wandering or running away from supervision (i.e. elopement), which can include leaving the house in the middle of the night or getting lost from a parent in a crowded location. Elopement can result in injury when the child is not supervised and is incredibly stressful for parents. Research suggests that behavioral intervention can help with elopement. However, most studies include only a few children. In addition, treatment strategies differ across studies, making it difficult to compare outcomes. The function-based elopement treatment has compiled strategies across different studies to build a 12-session treatment manual that can be followed by clinicians. The manual guides the therapist on the delivery of parent-training strategies to improve the child's safety and reduce elopement. We compared function-based elopement treatment to a control condition where parents met weekly with a clinician for more general parent training. Children whose parents received function-based elopement treatment showed greater improvement in elopement than children whose parents received more general parent education. This result suggests that the treatment works. Further study is needed to move function-based elopement treatment into clinical practice.
