Intensive Behavioral Treatment for Children with Autism: Four-Year Outcome and Predictors
Sallows et al., 2005

RESULT: A comparison of a clinic-directed ABA program consisting of 37 hours per week of ABA for 35 months versus a parent-directed ABA program consisting of 31 hours per week of ABA for 37 months showed that the parent-directed ABA program was more effective than the clinic-directed ABA program. In other words, parents who are trained in ABA and who implement the intensive therapy had better outcomes than training RBT's to conduct the therapy.

  • Clinic-Directed Group

    • Start — 50.85

    • End — 73.08

  • Parent-Directed Group​​​

    • Start — 52.10

    • End — 79.60
