Co-treatment as an approach to providing services to children who use augmentative and alternative communication: lessons learned from a model program

The purpose of the current study was to explore how speech-language pathologists (SLPs) and occupational therapists (OTs) approach co-treatment sessions for children who use augmentative and alternative communication (AAC). Given a lack of research to date on co-treatment between SLPs and OTs, an initial investigation into the relationship between the professions in this setting was warranted. Semi-structured interviews were conducted with 10 dyads of SLPs and OTs with experience treating children who use AAC together. Interviews were conducted either in-person or virtually and then were transcribed for thematic analysis. Reliability measures were completed. Four primary themes emerged from the interviews with 16 subthemes. Results indicated that SLPs and OTs consider their caseload and activities when preparing before sessions. During sessions, considerations include AAC use, communication strategies, and safety. After sessions, SLPs and OTs debrief and educate caregivers. Benefits and barriers to co-treatment were also noted. SLPs and OTs noted a number of factors that impact their co-treatment sessions with AAC users. Results of the study demonstrate that SLPs and OTs can collaborate with this population and feel that the model of care is beneficial.
