This randomized multiple-baseline single-case experimental study examined three young autistic children during dynamic, play-based naturalistic developmental behavioral intervention (NDBI). It assessed joint engagement after introducing NDBI strategies, then after adding aided augmentative and alternative communication modeling and just-in-time programming of visual scene displays (VSDs). NDBI strategies produced a large positive effect on joint engagement and a corresponding large negative effect on isolated attention. Outcomes after the AAC and VSD components were added were mixed. The findings suggest potential for VSDs as a communication support within play-based NDBI, but do not establish consistent added effects.

Key findings

  • Introducing NDBI strategies had a large positive effect on child joint engagement.
  • NDBI strategies had a corresponding large negative effect on child isolated attention.
  • After aided AAC modeling and just-in-time VSD programming were added, joint engagement and isolated attention outcomes were mixed.

Why it matters

Joint engagement and isolated attention are relevant to social communication during play. The findings indicate that play-based NDBI strategies may support joint engagement in young autistic children, while the mixed outcomes after adding VSD-related components leave their additional contribution uncertain. This distinction can inform interpretation of early single-case evidence on combining behavioral intervention and AAC supports.

What to keep in mind

The study included three participants and used a single-case experimental design; outcomes after adding AAC modeling and VSD programming were mixed.
