A systematic review of training programs for parents of children with autism spectrum disorders: single subject contributions.

Patterson et al. (2012) looked at every single-subject parent-training paper they could find for kids with autism. They pulled 11 studies that taught parents how to boost child communication. Each study used single-case designs, so parents acted as their own baseline.

Right after training, parents used the new skills and kids talked more. The gains stayed shaky. Few studies checked if parents kept the tactics weeks later. Generalization data was thin.

Gerow et al. (2018) later focused on parent FCT and saw the same quick win, same fade-out pattern. Ouyang et al. (2024) went further. Their 2024 network meta of 32 RCTs showed parents can hit high fidelity if you stage the training: start with ImPACT, add ESDM, finish with PRT.

That looks like a contradiction. Y et al. said maintenance is weak, but Ouyang et al. claim high fidelity. The gap is design. Y et al. pooled early SSRDs with little follow-up. Ouyang et al. only included newer RCTs that added booster sessions and phone check-ins.

Bozkus-Genc et al. (2024) prove the staged idea works. Parents mastered PRT moves by week 5-6 and toddlers kept social gains after 12 short sessions. The field has moved from “parents can learn” to “parents keep the skill if you support them longer.”

Stop treating parent training as a one-off workshop. Use a stepped plan: teach, coach, then taper with remote check-ins. Schedule brief booster sessions at 1, 3, and 6 months. You will keep parent fidelity high and lock in child gains.
