Sure. In some ABA therapy setups, the therapists were so obsessed with achieving quick results that they didn't respect the child's natural pace of development. For example, a child who was just starting to communicate verbally was pushed too hard to form complete sentences immediately. This put a lot of pressure on the child and made them reluctant to communicate at all.
There are reports of ABA therapy where the family was not involved in the decision - making process adequately. The therapists made all the plans without really understanding the family's values and the home environment. So, the therapy that was implemented didn't mesh well with the child's overall life, like the child being taught skills that were not relevant or useful in their home setting, which was really a waste of time and resources and also a source of stress for the child.
