Linking implementation of evidence-based parenting programs to outcomes in early intervention.

In the field of early intervention, only a few studies of parenting interventions include both participant and facilitator behaviors. Fidelity and supervision (facilitator characteristics) and dosage and satisfaction (participant characteristics) were tested on the outcome of improved parenting style in a sample of 36 parents of young children with disabilities. Results indicated that the facilitator behavior of fidelity was significantly and negatively related to the program outcome of parenting style; no effect was found for the facilitator behavior of supervision. For the participant behaviors, both dosage and satisfaction had non-significant relationships with the program outcome of parenting style at follow-up. The surprising negative relationship between content fidelity and parenting style was discussed.Two possible explanations were: (1) process or quality of intervention delivery is more influential than content fidelity, which considers only adherence to the intervention manual, and (2) the developmental stage of early intervention families calls for more focus on relationships between facilitators and parents and less on content of the specific intervention.
