Evaluating a more cost-efficient alternative to providing in-home feedback to parents: the use of spousal feedback.

Researchers taught six parents of children with autism how to run teaching sessions at home. After the basic class, they asked each parent's spouse to give simple feedback during daily routines.

They used a multiple-baseline design. No extra clinic visits were needed once the spouses began coaching each other.

Five of the six parents already improved with the first class. Adding spouse feedback pushed their skills even higher. The sixth parent stayed flat, but no one lost ground.

The gains stayed up without more professional contact. Cost dropped because the team did not return to the house.

Parsons et al. (1981) did the first spouse-to-spouse test. One mother learned dressing drills in clinic, then trained her husband at home. The 1998 paper keeps the same idea but adds a clear feedback step, making the process easier to copy.

Bhaumik et al. (2008) later showed that feedback also lifts teacher fidelity. Taken together, the three studies say: give feedback, no matter who receives it — parent, spouse, or teacher.

Zhu et al. (2020) looks different on the surface. They used Zoom to give remote feedback to BCBA trainees. Both papers aim to cut travel costs, one through spouses, the other through screens. Same goal, two cheap paths.

You can stretch your caseload without burning hours on the road. Train one parent, then script the spouse to praise, prompt, and correct during nightly play or meal routines. One brief role-play at clinic is enough. You save drive time, and the family keeps improving after you leave. Try adding a simple check-sheet: spouse marks + or – for each teaching step, then gives a quick “good job” or “try wait time.” You will likely see the same bump the study found, at zero extra cost.
