STEP was developed and published by the psychologists Don Dinkmeyer Sr., Gary D. McKay and Don Dinkmeyer Jr. The publication was supplemented by an extensive concept for training and proliferation. STEP has reached more than 4 million parents and has been translated into: Spanish, French, German, Japanese and is presently working on Korean and Chinese adoptions.
An evaluation of the program found that parents who participated in STEP had more positive perceptions of their children and were less likely to abuse them.Dana C. Fennell and Anne H. Fishel, Journal of Child and Adolescent Psychiatric Nursing, vol. 11, no. 3 (2001) pp. 107-120.
