Faciliter les échanges avec les personnes vivant avec un trouble de la communication : une formation pour les chauffeur·e·s de transport adapté

Communicating with family and friends, as well as with unfamiliar partners such as grocery store or pharmacy staff, is at the heart of many activities that enable satisfactory social participation. However, to achieve an inclusive society, human adaptations are essential for people living with a communication disability. Indeed, difficult interactions with individuals encountered in their community(ies) could restrict their social participation. In particular, their access to public transportation seems to be hindered by staff attitude and communication skills. Considering the key role of public transport in social participation, this thesis presents a research project that aims to improve interactions between adapted transport drivers and their passengers living with a communication disability.  A communication partner training program, a speech-language pathology intervention aiming to train communication partner to better interact with people living with a communication disability, has been developed specifically for drivers of an adapted transport service in a large Quebec city. Its development was guided by a model from the field of adult education, the andragogical process model for learning. The training entitled Accessible Communication in Public Transportation was offered to thirteen adapted transport drivers. Its effects on the drivers were explored using an exploratory single-group design.  The first study of the thesis is a scoping review. It describes the scientific literature on paid worker and unfamiliar partner communication training aiming to improve communication with people living with one or more acquired neurogenic communication disorders. The findings of this study are that the majority of communication partner training programs are disorder-specific and that they are mainly offered to health care staff or students. Despite variability in the measures used in the studies, the reported effects were promising for improving interactions between the people trained and individuals living with a communication disability.  The second study of the thesis explores the usefulness of the andragogical process model for learning. The study points out that the model is useful for developing, delivering, and evaluating a workplace training that seemed to be appreciated by participants, even though the majority of the model's elements were adapted to meet organizational constraints. The study also points out that the assessment of learning needs, the establishment of an atmosphere of caring, acceptance, trust and respect conducive to learning, and the choice of training methods appear to be key elements of the model.   The third study explores the effects of the communication partner training on thirteen adapted transport drivers. After being trained, the drivers appeared to have more knowledge about communicating with a person living with a communication disability. In addition, analysis of videos of the travel of passengers living with a communication disability by the driver-participants reveals that the drivers improved their relational communication and increased the number of gestures used with these passengers.  This thesis suggests that a communication partner training based on adult education theories has the potential to improve interactions between adapted transport drivers and people living with communication disabilities. It lays the groundwork for further studies to evaluate the effectiveness and understand further the effects of similar trainings. This thesis reaffirms the importance of research on communication partner training as a promising intervention to realize a more inclusive society for people living with communication disabilities.
