Longitudinal Change in Response Processes: A Response Shift Perspective

  • Chapter
  • First Online:

Part of the book series: Social Indicators Research Series ((SINS,volume 69))

Abstract

This chapter focuses on the examination of response shift in patient-reported outcomes (PROs) research, with particular attention to measurement validity and response processes. Response shift occurs when changes in PROs over time are the result of changes in how people interpret and respond to PRO measurement items at different points in time. Conceptual foundations of response shift are discussed, followed by a review of statistical methods for examining response shift. The chapter concludes with a discussion of opportunities and challenges for response shift research. We specifically consider that, although response shift is inherently about response processes and measurement validation, most of the methods and applications of response shift are descriptive in nature with an eye towards detecting and controlling for response shift. There is significant opportunity for theoretical and methodological development in focusing on understanding the mechanisms (mediators, moderators and other causes) by which response shift occurs when measuring PROs.
