According to the APSAC Task Force, there are controversies within the attachment therapy community about coercive practices. There has been a move away from coercive and confrontational models towards attunement and emotional regulation amongst some leaders in the field, notably Hughes, Kelly and Popper. A number of therapies are quite different from those that have led to the abuse and deaths of children in much publicized court cases. The Task Force, however, points out that all the therapies, including those using frankly coercive practices, present themselves as humane, respectful and nurturing, therefore caution is advised. Some practitioners condemn the most dangerous techniques but continue to practice other coercive techniques. Others have taken a public stand against coercion. The Task Force was of the view that all could benefit from more transparency and specificity as to how the therapy is behaviorally delivered.
