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 .
Increased Affective Bias Revealed Using Experimental Graded Heat Stimuli in Young Depressed Adults: Evidence of “Emotional Allodynia”
Objective : To examine the hypothesis that young adults with major depressive disorder ( MDD ) would show increased affective bias to painful and nonpainful experimental heat stimuli , as evidence d by an increased responsiveness to warm and hot temperatures . Pain and depression often occur together . Pain is both a sensation and an affective experience . Similarly , depression is associated frequently with somatic symptoms as well as emotional dysphoria . Existing evidence indicates that MDD may be associated with altered pain processing . However , the extent to which alterations in experimentally controlled heat pain sensations are related to increased affective bias in MDD is unknown . Method : Grade d nonnoxious and noxious heat stimuli were delivered r and omly with a thermode applied to the volar surface of the left arm of 15 unmedicated subjects with current MDD and 15 age- and gender-matched healthy comparison subjects . MDD and non-MDD subjects rated the intensity and unpleasantness of all stimuli . Results : Two main results were observed . First , MDD relative to non-MDD subjects showed decreased heat pain thresholds . Second , a significantly increased affective bias ( unpleasantness/intensity ) was observed in subjects with MDD , particularly over the range of nonnoxious heat stimuli . This bias was independent of the change in sensory pain thresholds . Conclusion : These findings represent corroborative evidence of abnormal affective heat pain processing in young adults with MDD , and suggest that MDD is associated with “ emotional allodynia , ” a qualitatively altered negative emotional response to normally nonaversive thermal stimuli . MDD = major depressive disorder
