PROMIS Fatigue

PROMIS. "Fatigue" user manual and scoring instructions.

Key findings used in wiki

  • PROMIS treats fatigue as a distinct physical-strain construct with standardized T-score interpretation and its own reference populations.
  • Items cover both the experience of fatigue (tiredness, exhaustion, lack of energy) and its impact on everyday functioning, not just subjective tiredness.
  • Fatigue is measured separately from depression and anxiety because physical depletion, low mood, and anxiety do not move together and are not interchangeable in treatment or support planning.
  • In GiveCare's methodology pages, this supports the argument that caregiver strain includes a physical-depletion dimension that a burden-only screen may under-represent.
