Adherence
A 1-point change on patient-reported outcome (PRO) measures (SF-36v2 and IWQOL-Lite-CT) represents a meaningful improvement in physical functioning from the patient's perspective.
When tracking your progress using standard health surveys, a small 1-point improvement on specific physical function questions is considered a meaningful, noticeable benefit by patients, indicating that treatment is working.
ModerateSupportsMEDIUM confidence
Participants indicated that an item-level 1-point score change on each measure would represent a noticeable improvement in physical functioning and indicate treatment success.
Why this rating
Based on qualitative cognitive debriefing with a small sample (n=33), not a large-scale statistical analysis.
