People with disabilities or special needs can benefit from AI-based conversational agents, which are used in competence training and well-being management. Assessment of the quality of interactions with these chatbots is key to being able to reduce dissatisfaction with them and to understand their potential long-term benefits. This will in turn help to increase adherence to their use, thereby improving the quality of life of the large population of end-users that they are able to serve. We systematically reviewed the literature on methods of assessing the perceived quality of interactions with chatbots, and identified only 15 of 192 papers on this topic that included people with disabilities or special needs in their assessments. The results also highlighted the lack of a shared theoretical framework for assessing the perceived quality of interactions with chatbots. Systematic procedures based on reliable and valid methodologies continue to be needed in this field. The current lack of reliable tools and systematic methods for assessing chatbots for people with disabilities and special needs is concerning, and may lead to unreliable systems entering the market with disruptive consequences for users. Three major conclusions can be drawn from this systematic analysis: (i) researchers should adopt consolidated and comparable methodologies to rule out risks in use; (ii) the constructs of satisfaction and acceptability are different, and should be measured separately; (iii) dedicated tools and methods for assessing the quality of interaction with chatbots should be developed and used to enable the generation of comparable evidence.
