The concept of the "authorship of their own lives in people with disabilities" belongs to the trend which creates a positive, capable image of a person with disability in the society. The aim of this article is to relate contemporary theories which conceptualise disability in the categories of a universal human condition, natural human variation and positive aspects of human functioning to AOL-PwD. In particular, the analyses in this work aim to locate AOL-PwD in the perspective of the theories of coherence, well-being, self-determination, quality of life and social belonging. The analysis has allowed to formulate the following theses: (1) the classical theory of needs by Abraham Maslow provides a significant foundation and the leading context for the general explication of the "authorship of their own lives in people with disabilities" idea; (2) the connections between identity and various dimensions of human functioning make it possible to predict the relations of these dimensions with AOL-PwD; (3) specific aspects of the "authorship of their own lives in people with disabilities" can be presented in the light of relevant theories; (4) the AOL-PwD construct is a complex composition of diverse relations and dependencies; (5) the "authorship of their own lives in people with disabilities" concept refers to the holistic model of a person with disability and illustrates comprehensively the specific composition of his or her mental and social condition.
