Background:\u00a0<\/strong>Myalgic encephalomyelitis and chronic fatigue syndrome have case definitions with varying criteria, but almost all criteria require an individual to have a substantial reduction in activity level.<\/p>\n Unfortunately, a consensus has not been reached regarding what constitutes substantial reductions.<\/p>\n One measure that has been used to measure substantial reduction is the Medical Outcomes Study Short-Form-36 Health Survey (SF-36). [1]<\/p>\n Purpose:\u00a0<\/strong>The current study examined the relationship between the SF-36, a measure of current functioning, and a self-report measure of the percent reduction in hours spent on activities.<\/p>\n Results:\u00a0<\/strong>Findings indicated that select subscales of the SF-36 accurately measure significant reductions in functioning.<\/p>\n Further, this measure significantly differentiates patients from controls.<\/p>\n Conclusion:\u00a0<\/strong>Determining what constitutes a significant reduction in activity is difficult because it is subjective to the individual.<\/p>\n However, certain subscales of the SF-36 could provide a uniform way to accurately measure and define substantial reductions in functioning.<\/p>\n Assessing current functioning as a measure of significant reduction in activity level<\/a>, by\u00a0Taylor Thorpe, Stephanie McManimen, Kristen Gleason, Jamie Stoothoff, Julia L.
