Mediating Parent Learning to Promote Social Communication for Toddlers with Autism: Effects from a Randomized Controlled Trial.

Schertz et al. (2018) ran a randomized trial with toddlers who have autism. Parents got 32 weekly home visits. Coaches taught them to use Joint Attention Mediated Learning (JAML) during normal play. The goal was more shared looks, points, and turns.

Kids in JAML showed clear gains in preverbal social communication right after the program. Most skills stayed strong six months later. Parents kept using the strategies without extra coaching.

Hong et al. (2018) looked at 67 caregiver studies and found many lose steam after coaching stops. JAML’s six-month hold fits the few plans that build generalization into every session.

Weiss et al. (2021) saw toddlers with autism stay flat on joint attention during free play. JAML’s positive curve seems to clash, but W used short lab clips while JAML taught parents across months—time and method explain the gap.

Lee et al. (2023) copied JAML’s targets over telehealth for one child and also saw gains. Moving the same steps online keeps the effect, hinting you can trade couch visits for Zoom when needed.

You can teach parents a simple routine—watch, wait, wonder aloud—and see lasting joint-attention growth. Build generalization into each home visit so parents practice at the park, store, and grandma’s house. If travel is tight, try telehealth; the steps still work. Start early, stay consistent, and let the toddler lead the toy.
