Rethinking device abandonment: a capability approach focused model.

It is estimated that approximately 97 million people in the world have complex communication needs and may benefit from alternative and augmentative communication (AAC). Although AAC is considered an evidenced-based intervention, device abandonment remains common, and researchers have attempted to analyze the causes of people abandoning devices. These devices have been prescribed following extensive assessment and often a protracted period of negotiation with a funding body. In this paper, we present the process of AAC prescription using a new model called the Communication Capability Approach by adding the Capability Approach from Amartya Sen to the widely used Participation Model. This allows clinicians to see individual daily decision-making as a valid choice of the individual. We propose reframing the concept of device abandonment as the person and their family making a choice to use a full range of multimodal communication to meet their own needs. This changes the tone of the narrative to viewing the person using AAC as competent and able to exercise self-determination and agency in this decision rather than as abandoning the device. AAC choices can be made on a day-to-day basis, according to the context of use so that people do not abandon devices but rather use whichever mode of communication is appropriate to the context.
