Is DIR/Floortime® evidence-based?
A relationship-based approach supported by a growing body of research — including a randomized controlled trial of parent-led, home-based intervention.
DIR/Floortime® is a relationship-based approach supported by a growing body of research. Studies show that when caregivers follow their child’s lead through play, children often make meaningful gains in communication, emotional connection, and social skills.
Research also highlights the importance of using Floortime in everyday environments like home and community settings. When strategies are embedded into daily routines — playtime, mealtime, transitions — children have more natural opportunities to learn and practise new skills.
One of the most consistent findings across studies is the role of parent and caregiver involvement. When caregivers are actively engaged, children show stronger progress in engagement, interaction, and overall development.
Larger studies are still ongoing. Current research and clinical experience consistently support Floortime as an approach that helps build strong relationships, increase engagement, and support long-term developmental growth.
