Comparative responsiveness and minimally important difference of Fatigue Symptom Inventory (FSI) scales and the FSI-3 in trials with cancer survivors.

ABSTRACT:

Background

Fatigue is a highly prevalent and disabling symptom in cancer survivors. Although many measures have been developed to assess survivors' fatigue, their ability to accurately capture change following intervention has rarely been assessed in post-treatment survivors. Ultra-brief fatigue measures are preferable in clinical practice but have limited evidence supporting their use with cancer survivors. We examined the psychometric properties of four Fatigue Symptom Inventory (FSI) measures, including the new FSI-3, in cancer survivors. Examined properties included responsiveness to change and minimally important differences (MIDs).

Methods

We analyzed data from three randomized controlled trials with post-treatment cancer survivors (N = 328). Responsiveness to change w
