Estimating meaningful change for The Impact of Weight on Self-Perception (IW-SP) questionnaire among people with type 2 diabetes.

ABSTRACT:

Purpose

The Impact of Weight on Self-perception Questionnaire (IW-SP) is a three-item patient-reported outcome measure (PROM) instrument assessing the impact of body weight on self-perception. To date no published threshold for meaningful change exists. The objective of this study was to estimate the minimal important change (MIC) for the IW-SP among people with type 2 diabetes.

Methods

Responder analyses were conducted using anchor- and distribution-based approaches with existing clinical trial data (SURPASS-2). As SURPASS-2 did not include a priori anchors, a set of alternative exploratory anchors were identified based on the MICs and items from two conceptually related measures used in the trial as well as percent change in body weight. Exploratory anchors with change est
