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 .
Randomized phase III clinical trial of five different arms of treatment for patients with cancer cachexia: interim results.
OBJECTIVE In April 2005 a phase III r and omized study was started to establish which was the most effective and safest treatment of cancer-related anorexia/cachexia syndrome and oxidative stress in improving identified primary endpoints : increase of lean body mass , decrease of resting energy expenditure ( REE ) , increase of total daily physical activity , decrease of interleukin-6 and tumor necrosis factor-alpha , and improvement of fatigue assessed by the Multidimensional Fatigue Symptom Inventory-Short Form ( MFSI-SF ) . METHODS All patients were given as basic treatment polyphenols plus antioxidant agents alpha-lipoic acid , carbocysteine , and vitamins A , C , and E , all orally . Patients were then r and omized to one of the following five arms : 1 ) medroxyprogesterone acetate/megestrol acetate ; 2 ) pharmacologic nutritional support containing eicosapentaenoic acid ; 3 ) L-carnitine ; 4 ) thalidomide ; or 5 ) medroxyprogesterone acetate/megestrol acetate plus pharmacologic nutritional support plus L-carnitine plus thalidomide . Treatment duration was 4 mo . The sample comprised 475 patients . RESULTS By January 2007 , 125 patients , well balanced for all clinical characteristics , were included . No severe side effects were observed . As for efficacy , an interim analysis on 125 patients showed an improvement of at least one primary endpoint in arms 3 , 4 , and 5 , whereas arm 2 showed a significant worsening of lean body mass , REE , and MFSI-SF . Analysis of variance comparing the change of primary endpoints between arms showed a significant improvement of REE in favor of arm 5 versus arm 2 and a significant improvement of MFSI-SF in favor of arms 1 , 3 , and 5 versus arm 2 . A significant inferiority of arm 2 versus arms 3 , 4 , and 5 for the primary endpoints lean body mass , REE , and MFSI-SF was observed on the basis of t test for changes . CONCLUSION The interim results obtained thus far seem to suggest that the most effective treatment for cancer-related anorexia/cachexia syndrome and oxidative stress should be a combination regimen . The study is still in progress and the final results should confirm these data
