It's great you're looking into the impacts of ABA and ESDM! A 2025 study showed both therapies lead to significant improvements in autistic children over six months. Interestingly, ESDM showed greater gains in social skills, while ABA excelled in gross motor skills. This suggests matching therapies to specific needs could be beneficial [1].

Even low-intensity ESDM (3 hours/week) has shown meaningful improvements in imitation and language [3]. Meta-analyses confirm ESDM boosts cognition and language in young children [5]. Parent-led ABA has also shown improved skill acquisition [4].
