In common with other professions social workers have the power to articulate certain ''truths'' about the people who use their services (Hare Mustin, 1994). These knowledge statements about people, often situated in case files may become the only background information of the lived experience for people with disability (Gillman, Swain, & Heyman, 1997). Social workers need to develop interviewing, assessment and recording practices that give precedent to the worldview of service users, if they are to truly understand and respond effectively to people's lives (Bigby, 2007). One such way of doing this is by adopting a life story approach to working with vulnerable people, which can provide a holistic stance to a person's social reality (Ortiz, 1985). This article outlines the use of this approach in research with Queensland ex-prisoners who were labelled as having an intellectual disability. By explaining the process used by the first author (hereafter known as the researcher), the methodological findings of this study illustrate how life story work can contribute to social work practice.
