Emotional Dysregulation in Preschoolers with Autism Spectrum Disorder-A Sample of Romanian Children.
Heart-rate watches confirm FCT calms kids but will not forecast meltdowns.
01Research in Context
What this study did
Three Romanian preschoolers with autism wore cheap heart-rate watches during FCT sessions.
The team wanted to know if heart-rate spikes could warn teachers before an outburst started.
What they found
FCT shortened outbursts and lowered heart rate for two kids.
The watch data, however, did not give a clear heads-up that a meltdown was coming.
How this fits with other research
Lindgren et al. (2020) ran a larger parent-coach trial over telehealth and saw a 98% drop in problem behavior within 12 weeks. Their success gives you confidence that FCT works; the Romanian study just adds a heart-rate band-aid.
Tassé et al. (2013) first paired heart-rate and behavior data in kids with autism and ID. They showed anxiety spikes lined up with more problem behavior, setting the table for wearables in FBA.
Sullivan et al. (2026) strapped EDA watches on therapists during functional analyses and caught stress spikes when kids acted out. Together these papers say: biosensors can track arousal in both parties, but they are not crystal balls.
Why it matters
You can keep using off-the-shelf heart-rate watches to show parents that FCT calms the body, not just the behavior. Do not rely on the watch to predict meltdowns—watch the antecedents you already know. Pair the data with your ABC notes to build buy-in for communication training.

03Original abstract
Emotional dysregulation problems seem to affect more than 80% of people with autism spectrum disorder (ASD) and may include irritability, aggressive behaviors, self-injury, and anxiety. Even though these types of problems are very common and affect the well-being of individuals with ASD, there are no objective assessment tools developed for this population and there are only a few intervention techniques meant to address these symptoms. This study investigates the feasibility of using off-the-shelf wearable devices to accurately measure heart rate, which has been associated with emotional dysregulation, and to test the effectiveness of functional communication training in reducing the emotional outburst in preschoolers with ASD. We used a single-case experiment design with three preschoolers with ASD to test if the duration of the emotional outburst and the elevated heart rate levels can be reduced by using functional communication training. Our results show that for two of the participants, the intervention was effective in reducing the duration of behaviors associated with emotional outburst, and that there were significant differences between baseline and intervention phase in terms of heart rate levels. However, our results are inconclusive regarding the association between elevated heart rates and the occurrence of the emotional outburst. Nevertheless, more research is needed to investigate the use of off-the-shelf wearable devices in predicting challenging behaviors in children with ASD.
