Kemampuan untuk melakukan komunikasi dua arah merupakan masalah utama anak dengan autisme. Pendekatan DIR/Floortime merupakan pendekatan multi disiplin yang fokus meningkatkan kualitas komunikasi dan interaksi antara caregiver dan anak. Penelitian ini menggunakan desain penelitian single case design (N=1), yang bertujuan untuk melihat efektivitas penerapan prinsip DIR/Floortime untuk meningkatkan kualitas komunikasi dua arah antara ibu dan anak dengan autisme. Peningkatan kualitas komunikasi dua arah diukur melalui peningkatan frekuensi Circle of Communication (CoC) dan skor Functional Emotional Assesment Scale (FEAS) ibu dan anak. Penelitian ini juga menggunakan alat ukur penunjang untuk mengetahui profil biologis ibu dan anak, yaitu Sensory Processing Motor Planning Questionnaire (SPMPQ) dan Observe Child's Behavior Challenge (OCBC).
