The MFSI-SF demonstrated moderate test-retest reliability in a small number of studies .
The MFSI-SF fatigue subscales were positively correlated with measures of distress , depressive , and anxious symptoms .
Purpose Fatigue is a subjective complaint that is believed to be multifactorial in its etiology and multidimensional in its expression .
Fatigue may be experienced by individuals in different dimensions as physical , mental , and emotional tiredness .
The purpose s of this study were to review and characterize the use of the 30-item Multidimensional Fatigue Symptom Inventory-Short Form ( MFSI-SF ) in published studies and to evaluate the available evidence for its psychometric properties .
Light treatment prevents fatigue in women undergoing chemotherapy for breast cancer
Purpose Fatigue is one of the most disturbing complaints of cancer patients and is often the reason for discontinuing treatment . This r and omized controlled study tested the hypothesis that increased morning bright light , compared to dim light , would result in less fatigue in women with breast cancer undergoing chemotherapy . Methods Thirty-nine women newly diagnosed with stage I – III breast cancer were r and omized to either  bright white light ( BWL ) or dim red light ( DRL ) treatment and were instructed to use the light box for 30 min every morning throughout the first four cycles of chemotherapy . The Multidimensional Fatigue Symptom Inventory was administered prior to the start of chemotherapy ( baseline ) , during the chemotherapy treatment week of cycle 1 ( C1TW ) , the last week ( recovery week ) of cycle 1 ( C1RW ) , the chemotherapy treatment week of cycle 4 ( C4TW ) , and the last week ( recovery week ) of cycle 4 ( C4RW ) . Results The DRL group reported increased fatigue at C1TW ( p = 0.003 ) and C4TW ( p < 0.001 ) compared to baseline , while there was no significant change from baseline in the BWL group . A secondary analysis showed that the increases in fatigue levels in the DRL group were not mediated through nor associated with changes in sleep or in circadian rhythms as measured with wrist actigraphy . Conclusions The results of this study suggest that morning bright light treatment may prevent overall fatigue from worsening during chemotherapy . Although our hypothesis that overall fatigue would improve with bright light treatment was not supported , the lack of deterioration in total fatigue scores suggests that bright morning light may be a useful intervention during chemotherapy for breast cancer
