Currently, there are a several measures which can assess headache disability, but there is a significant burden to assess each individual symptom given this heterogeneous polymorbid population. The objective of this proposed study was to validate the single headache item from the Neurobehavioral Symptom Inventory (NSI) compared to the 6-item Headache Impact Test (HIT-6).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Materials and Methods<\/jats:title>\n                  <jats:p>Participants included consecutive treatment-seeking outpatients at the Brain Injury Rehabilitation Service at the Brooke Army Medical Center from August 2007 to January 2010 who were administered a battery of assessment measures at initial intake, as part of usual care. Archival record review was conducted using procedures approved by the local Institutional Review Board. Inclusionary criteria included completion of both the HIT-6 and NSI. Participants with a cut-off score of &gt;22 on the NSI Validity-10 were excluded in a post hoc analysis to validate findings among those who passed validity screen.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The Pearson correlation between the single-item NSI headache measure and the HIT-6 revealed at least 64% shared variance in this military sample (r = 0.8, p &lt; 0.001), indication a high association between the two measures.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The NSI single-item headache measure adequately captured headache severity in this military cohort. Use of the single-item NSI headache measure may minimize survey burden on participants whose primary complaint is not headaches, or who present with multiple symptoms. Future studies are needed to validate the single-item headache measure in other samples.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/milmed\/usz173","type":"journal-article","created":{"date-parts":[[2019,7,23]],"date-time":"2019-07-23T17:00:02Z","timestamp":1563901202000},"source":"Crossref","is-referenced-by-count":4,"title":["Single-Item Versus Multiple-Item Headache Ratings in Service Members Seeking Treatment for Brain Injury"],"prefix":"10.1093","author":[{"given":"Lisa H","family":"Lu","sequence":"first","affiliation":[{"name":"Defense and Veterans Brain Injury Center, Neurology Service, Brooke Army Medical Center, 3551 Roger Brooke Dr, JBSA Ft Sam Houston, TX"},{"name":"General Dynamics Information Technology, San Antonio, TX"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3690-1906","authenticated-orcid":false,"given":"Amy O","family":"Bowles","sequence":"additional","affiliation":[{"name":"Brain Injury Rehabilitation Service, Department of Rehabilitation Medicine, Brooke Army Medical Center, 3551 Roger Brooke Dr, JBSA Ft Sam Houston, TX"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan E","family":"Kennedy","sequence":"additional","affiliation":[{"name":"Defense and Veterans Brain Injury Center, Neurology Service, Brooke Army Medical Center, 3551 Roger Brooke Dr, JBSA Ft Sam Houston, TX"},{"name":"General Dynamics Information Technology, San Antonio, TX"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Blessen C","family":"Eapen","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, VA Greater Los Angeles Health Care System, 11301 Wilshire Blvd, Los Angeles, CA"},{"name":"Department of Medicine, David Geffen School of Medicine at UCLA, 10833 Le Conte Ave, Los Angeles, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Douglas B","family":"Cooper","sequence":"additional","affiliation":[{"name":"General Dynamics Information Technology, San Antonio, TX"},{"name":"Defense and Veterans Brain Injury Center, Polytrauma Rehabilitation Center, Audie L.
