Caregiver‐mediated joint attention intervention

Three preschoolers with moderate-to-severe autism got a new coach: their own parents. Hansen et al. (2018) taught each caregiver to run 10-minute joint-attention games at home two or three times a week.

The team used a multiple-baseline design. They waited for each parent to hit mastery before the next family started, so any jump in child skills could be pinned on the training.

Every child climbed from near-zero to high levels of both prompted and independent joint-attention responses. Gains showed up right after parents reached mastery and held while the study tracked them.

The brief, living-room sessions produced what the authors call 'substantial' improvements without extra clinic hours.

Chiang et al. (2016) tested a similar caregiver program but saw only modest gains at a three-month check. The key difference: their toddlers played movement games, while Hansen used shorter, simpler house-hold routines. Method tweak, bigger payoff.

Wong (2013) moved the same idea into preschool classrooms. Eight one-hour teacher-coaching sessions also lifted joint attention, showing the model works beyond mom and dad.

Patton et al. (2020) and Shillingsburg et al. (2022) pushed the skill further. They added script-fading and peer dyads and got generalized initiations across toys and people—something the 2018 study did not test. Think of Hansen as the 'first solid step'; these later papers add the 'travel anywhere' feature.

You can hand families a dirt-simple plan: pick a favorite toy, follow the child's lead, insert a point-and-look prompt, praise any shared gaze. Ten minutes, a few times a week, done in the home you already visit. Start there, then layer script-fading or peer practice if the child stalls or needs wider generalization.
