Variation in Behavior Analysts’ Treatment Intensity Recommendations for Patients with Autism Spectrum Disorder
BCBAs use inconsistent rules to set ABA hours, even though dose-response research exists.
01Research in Context
What this study did
The authors sent an online survey to 559 Board Certified Behavior Analysts.
They asked which child and family factors make BCBAs recommend more or fewer ABA hours.
Choices covered diagnosis, skills, problem behavior, family stress, insurance, and more.
What they found
Clinicians agreed on only two things: an autism diagnosis and big skill gaps mean more hours.
On every other factor—age, IQ, family income, problem behavior—BCBAs split.
Some said the same factor should raise hours; others said it should lower them.
How this fits with other research
Linstead et al. (2017) showed kids who get more hours master goals faster.
That dose-response idea is what clinicians try to apply, yet they disagree on the rules.
Ostrovsky et al. (2022) muddies the water: children improved no matter how many hours they got.
Those authors looked at real gains, not clinician guesses, and found hours did not predict progress.
Together the papers reveal a gap: clinicians use uneven rules to chase a dose effect that sometimes vanishes when tested.
Why it matters
You may be recommending 15 hours while a colleague recommends 35 for a similar child.
Until the field writes clear, data-based guidelines, insurance reviewers and families will keep seeing conflicting prescriptions.
Start tracking your own client outcomes by hours received; your data can help build the uniform rules we clearly lack.

03Original abstract
Most outcome research on Applied Behavior Analysis (ABA) treatment suggests that high intensity yields the best outcomes for patients with autism spectrum disorder (ASD). However, little is known about what impacts the determinations behavior analysts make regarding individualized treatment intensity recommendations. We conducted a cross-sectional survey of behavior analysts with experience developing and overseeing behavior analytic treatment for individuals with ASD (N = 559). We asked participants to report how 36 patient, familial, and logistical factors impact their treatment intensity recommendations using a 7-point Likert scale (ranging from significantly decrease to significantly increase recommended treatment intensity). Results indicated variation in the factors that impact recommendations as well as the direction of impact, with the greatest agreement that patient diagnosis and skills deficits lead to increased treatment intensity recommendations. Although the data reveal patterns and areas of seemingly greater consensus, the significant variability in clinicians’ approaches to individualizing treatment intensity recommendations indicates a need for future research on training and standards for clinicians to ensure appropriate treatment intensity recommendations are provided to all patients receiving ABA treatment.
