Life Story Research with People Aging with Intellectual Disabilities: An Adaptation of the Lifeline Interview Method

Abstract

A key feature of inclusive research is the accessibility of research procedures to meaningfully engage people with intellectual disabilities in research processes. Creating accessible research procedures requires innovations in methods traditionally used in research. This paper describes how the Lifeline Interview Method by Assink and Schroots was adapted and implemented in a study using life story research to better understand the experiences of older adults with intellectual disabilities. Twelve adults with intellectual disabilities over the age of 50 participated between two and seven times in interviews about their life histories. The interviewer assisted in the construction of timelines of key events in the participants’ individual life stories, and the participants decorated their lifelines throughout the course of the interviews. The lifeline process was an effective tool to engage the participants in the research process, support participation, and provide access for people with intellectual disabilities to retrieve their life experiences. Challenges in the lifeline process included barriers to gathering sufficient information to construct timelines and gatekeepers withholding access to information.
