Abstract

The purpose of this research was to conduct an examination of the concept of identity, particularly in relationship to potential threats to the sense of self. This involved a synthesis of theoretical perspectives on identity, as well as an evaluation of the nature and dimensions of identity in individual persons. The evolution of identity as a philosophical and psychological concept is described, with an emphasis on theories of identity in disciplines such as personality psychology, psychoanalysis, social psychology, developmental psychology, and neuropsychology. A qualitative research method, the grounded theory approach of Glaser & Strauss , was used to analyze data derived from semi-structured interviews with seven participants who had undergone significant life challenges. The rationale and procedure for the use of this method is provided, as well as a description of the researcher's analytic processes. The results of the data analysis are summarized and a description of the categories of identity is followed by a discussion of the theoretical model derived from the data analysis. In this model, self-identity was characterized as a network of structural processes operating along four dimensions, categorized as physical traits, personality traits, core values, and role structures. These identity contents are subject to change through a mechanism called self-stabilization and adaptation, an evaluative function of awareness of self and environment. The model is discussed with respect to existing theories and research, as well as the ramifications of the model for clinical practice and for future research
