Response Shift

Purpose of the Special Interest Group

The purpose of the response shift interest group is to bring together investigators and clinicians who are interested in the influence of response shift (a change in an individual’s values, internal standards, and conceptualization of QOL) on QOL assessments.

The ultimate objective is to better understand when and why response shift occurs such that healthcare professionals and researchers using patient reported outcomes across various disciplines can recognize and account for response shift.

Communication and Information Sharing

Response Shift Reference List: Dr. Mirjam Sprangers has graciously shared a list of response shift references with us. Click here to access the reference list.

If you notice that an article that you are aware of is missing, or you would like to add a new article of your own, please contact one of the co-chairs – we will update the list at least twice yearly.

Abstract reviews: Experienced response shift SIG members have offered to review abstracts for any investigator / student who would like feedback on their response shift related abstract prior to submitting the abstract to ISOQOL for peer review.

We encourage you to use this service! Please contact one of the co-chairs for information.
