Abstract

Developmental regression is characteristic of Rett syndrome and it also occurs in a number of other develop. mental disabilities. To assist clinicians in identifying promising therapeutic approaches, we identified 38 studies that sought to improve adaptive behavior functioning in cases where developmental regression had either already occurred or was likely to occur. Studies were summarized in terms of (a) participants, (b) intervention, (c) dependent variables, (d) outcomes, (e) study design, and (f) certainty of evidence. The available literature in. eluded 136 participants from preschoolers to adults. Most participants (n = 132) had Rett syndrome. Interventions targeted a range of dependent variables (e.g., challenging behavior, communication, motor, and play skills). Multi-component interventions derived from behavior analytic principles were the norm, suggesting the need for clinical expertise in the application of such principles. However, only 12 studies (with 44 participants) were rated as providing conclusive evidence of a positive intervention effect. Future research on the mechanisms underlying developmental regression might lead to new and more effective interventions.
