The importance of psychosocial aspects has been gradually recognised in the field of inclusive design. A critical review of existing literature, however, such as design, healthcare, psychology, and sociology, on psychosocial aspects of inclusivity identifies a two-fold research gap which is a limited understanding of both definition and dimensions of psychosocial inclusivity in the field of inclusive design. Such concept of psychosocial inclusivity is an inherently context-dependent and multi-faceted concept. Accordingly, a ‘personal mobility’ was focused on in this paper as one key context to explore psychosocial inclusivity to facilitate thorough and in-depth study of this concept. In this study, therefore, the interviews with 37 mobility-challenged participants were performed, and then the interview data was analysed by using a coding analyses to identify key psychosocial factors of inclusive design based on participants' lived-experiences.
