Development of a PROMIS multidimensional cancer-related fatigue (mCRF) form using modern psychometric techniques.

ABSTRACT:

Purpose

To develop a PRO assessment of multidimensional cancer-related fatigue based on the PROMIS fatigue assessments.

Method

Cancer patients reporting fatigue were recruited from a comprehensive cancer care center and completed a survey including 39 items from the PROMIS Cancer Item Bank-Fatigue. Component and factor structures of the fatigue items were explored with Monte Carlo parallel factor and Mokken analyses, respectively. Psychometric properties were determined using item response theory, ensuring unidimensionality, scalability, and item independence.

Results

Fatigue scores from a sample of 333 fatigued cancer patients (mean age = 59.50, SD = 11.62, 67% women) were used in all scale development analyses. Psychometric analyses yielded 3 dimensions: motivationa
