Response Shift: A Review of the Literature

1 Presentation 0 Sections

Organized By: Response Shift SIG

A number of methods for measuring and detecting response shift have been developed and tested. Our research team conducted a scoping review on the literature on response shift.
In this webinar, based on the results of our scoping review, participants will learn about the literature on response shift, the different types of response shift, the different statistical methods for detecting response shift, and future directions of research in the field.

Response shift (RS) refers to changes in an individual’s self-evaluation of his/her health status and quality of life because of changes in internal standards, values, or concepts. According to Sprangers and Schwartz (1999), there are three types of RS, including:

  1. Recalibration (change in internal standards of measurements)
  2. Reprioritization (change in prioritization of component domains constituting the target construct)
  3. Reconceptualization (redefinition of the target construct).RS has been investigated in a number of medical conditions where the diagnosis, or treatment, or other factors may act as catalysts that induce change in an individual’s self-perceptions of health status and quality of life.
It has been shown that response shift could influence assessments of treatment effects and changes in patients’ health status and quality of life over time.

Learning Outcomes/Objectives
After the webinar, the learner will be able to:
  • Know the results of our scoping review of the response shift literature
  • Explain the potential influence that response shift has on the assessment of treatment effects, as well as assessment of changes in patients’ health status and quality of life over time
  • Critically evaluate and consider the different commonly used statistical methods of response shift
  • Describe the role of response shift in measurement validation (with an emphasis on the modern theories of measurement validity)
