Low-quality evidence is likewise a concern in some research reporting on the potential harms of ABA on autistic children.<ref name="Davis2022">{{cite book |doi=10.1002/9781119679028.ch39 |chapter=Helping Autistic Children |title=The Wiley-Blackwell Handbook of Childhood Social Development |date=2022 | vauthors = Davis R, Den Houting J, Nordahl-Hansen A, Fletcher-Watson S |pages=729–746 |isbn=978-1-119-67898-4 |url=https://osf.io/zrfyp/ }}</ref>
Another concern is that ABA research only measures cognition or behavior as a means of success, which has led to a lack of qualitative research about autistic experiences of ABA, a lack of research examining the internal effects (e.g. mental health, well being, emotions) of ABA and a lack of research for autistic children who are [[Nonverbal autism|non-speaking]] or have comorbidco-occurring intellectual disabilities.<ref name=":0">{{Cite journal |vauthors=McGill O, Robinson A |date=October 2020 |title='Recalling hidden harms': autistic experiences of childhood applied behavioural analysis (ABA) |url=https://strathprints.strath.ac.uk/73753/1/McGill_Robinson_AA_2020_autistic_experiences_of_childhood_Applied_Behavioural_Analysis.pdf |journal=Advances in Autism |language=en |volume=7 |issue=4 |pages=269–282 |doi=10.1108/AIA-04-2020-0025 |s2cid=225282499}}</ref><ref name="Sandoval-Norton_2021">{{Cite journal |vauthors=Sandoval-Norton AH, Shkedy G, Shkedy D |date=June 2021 |title=Long-term ABA Therapy Is Abusive: A Response to Gorycki, Ruppel, and Zane |journal=Advances in Neurodevelopmental Disorders |language=en |volume=5 |issue=2 |pages=126–134 |doi=10.1007/s41252-021-00201-1 |s2cid=234848417 |doi-access=free}}</ref><ref name="Schreck-2000">{{cite journal | vauthors = Shreck KA, Metz B, Mulick JA, Smith A |year=2000 |title=Making it fit: A Provocative Look at Models of Early Intensive Behavioral Intervention for Children with Autism |journal=The Behavior Analyst Today |volume=1 |issue=3 |pages=27–32|doi=10.1037/h0099886 }}</ref><ref name="Weiss-2006">{{cite journal | vauthors = Weiss MJ, Delmolino L |year=2006 |title=The Relationship Between Early Learning Rates and Treatment Outcome For Children With Autism Receiving Intensive Home-Based Applied Behavior Analysis |journal=The Behavior Analyst Today |volume=7 |issue=1 |pages=96–105 |doi=10.1037/h0100140}}</ref> Research is also lacking about whether ABA is effective long-term and very little longitudinal outcomes have been studied.<ref name="Sandoval-Norton_2021" />
