What was measured

The Multidimensional Fatigue Inventory (MFI) is a 20-item self-report instrument designed to measure fatigue. It covers the following dimensions: General Fatigue, Physical Fatigue, Mental Fatigue, Reduced Motivation and Reduced Activity. Tested for its psychometric properties in cancer patients receiving radiotherapy, patients with the chronic fatigue syndrome, psychology students, medical students, army recruits and junior physicians, it was found to have good Test-retest Reliability (r=0.80) and great Internal Consistency (Cronbach's alpha = 0.92).

Analysis population: Instrument not used and data not collected.

Groups in this outcome

Circadian Active Bright White Light (BWL)

PEI Experimental Light: Ambient Light Fixture delivery of circadian active bright white light (BWL) installed in the patient's hospital room will turn on automatically and illuminate the hospital room from 7 to 10 AM each morning.

Circadian Inactive Dim White Light (DWL)

Comparison Light: Ambient Light Fixture delivery of circadian inactive dim white light (DWL) installed in the patient's hospital room will turn on automatically and illuminate the hospital room from 7 to 10 AM each morning.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
