Longitudinal Change in Response Processes: A Response Shift Perspective

Abstract

This chapter provides a review of response shift theories, methods, and applications in patient-reported outcomes (PROs) research, with particular consideration of measurement validity and response processes. PROs refer to appraisals from patients about their self-perceived health outcomes (e.g., physical, mental, and social) that are relevant to their quality of life. To this end, in the first section, we discuss conceptual foundations of response shift in relation to perspectives of measurement validity. In the second section, we review statistical methods with an eye to their ability to detect, accommodate, and/or explain different types of response shift. The third and final section focusses on opportunities and challenges for response shift research. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
