Fatigue.

8 catalogued instruments are currently grouped under this construct, across 2 domains: Clinical: broadband and severity; Health, quality of life and health psychology.

This grouping is editorial and provisional. It is derived from what each entry says it measures, it has not been reviewed instrument by instrument, and 195 catalogued instruments are not yet grouped under any construct. Treat the list as a starting point rather than a complete answer, and read each entry for what it actually covers.
