The modification of parent behavior. A review of generalization and maintenance.

Sobsey et al. (1983) read every parent-training paper they could find. They asked two questions. Do parents keep using the skills after the trainer leaves? Do the child’s new skills last?

They looked at how each study checked for long-term change. They also graded the methods.

Most papers stopped collecting data the day training ended. When follow-up data existed, the methods were weak. The review calls the field “under-studied and methodologically weak.”

Bruder (1986) and Burgio et al. (1986) answered the call. Both ran tight single-case tests. Parents learned skills and used them at home later. Kids kept the gains. These studies show the gap can be filled.

Conard et al. (2016) echoes the same worry in workplaces. OBM papers also quit measuring once the consultant leaves. Same problem, different setting.

Bassett-Gunter et al. (2017) push the idea further. They say we should track parent stress and self-efficacy, not just child skills. Verschuur et al. (2019) proved it works. Group PRT cut parent stress while kids gained language.

Together the chain shows: first we ignored follow-up, then we learned how to produce it, and now we measure parent well-being too.

Build maintenance into every parent program. Add a simple exit plan: written instructions, weekly check calls, and one-month data probe. Measure parent confidence at the same time you measure child targets. You will spot drop-off early and keep both generations progressing.
