"Finding Common Ground" - Impact of a Complex Intervention on Collaboration in Augmentative and Alternative Communication Care of People without Natural Speech.

Purpose: Many care settings are characterized by collaboration between a variety of stakeholders. People without natural speech who rely on augmentative and alternative communication (AAC) are often strongly dependent on the involved stakeholders and collaboration among them. Since collaboration can be challenged by many barriers, this study examines the impact of a complex intervention on collaboration in AAC care. Methods: In a quasi-experimental mixed methods intervention study which include AAC training, AAC therapy and case management, caregivers of AAC users were surveyed at 3 time points to assess collaboration and case management in the intervention versus comparison group. In addition, semi-structured focus group interviews were conducted with caregivers in the intervention group. Quantitative data were analyzed descriptively and by comparison of means. Qualitative data were analyzed using qualitative content analysis. Results: The Mann-Whitney Conclusion: The results show a positive impact of the intervention on the collaboration between stakeholders involved in AAC care - especially with active stakeholders. In particular, the organization of care and the accompanying case management by the AAC consultation centers seem to positively affect collaboration.
