Table 2 Characteristics of an ideal fatigue assessment tool (Adapted from Whitehead, 2009 [42])

From: Rethinking fatigue in Gaucher disease

Parameter Ideal tool
Scale usability • Easy to understand and complete
• Minimal burden for patient and physician
Clinical utility • Discriminates presence versus absence of fatigue with acceptable sensitivity and specificity
• Provides description of severity of fatigue and its impact
• Useful as outcome measure sensitive to changes with disease worsening or therapeutic intervention
Psychometric properties • Robust precision and accuracy
• Reliable and consistent with good reproducibility
• Stable and repeatable over time and among raters
• Possesses stable structure that measures what is intended
• Correlates reasonably with similar fatigue-specific tools
• Discriminates between different patient groups and symptoms
• Captures change in fatigue symptoms over time
