The longitudinal study showed that 81.6% of children surveyed within 4 weeks following a VAS campaign reportedly received VAS during the campaign and 13.4% of caregivers incorrectly reported receiving VAS when no campaign had actually occurred. False-positive reporting was more likely when oral polio vaccine (OPV) was distributed during the reporting period (20.6% vs 5.4%; P &lt; .001). Showing a photo of OPV during the interview reduced the odds ratio (OR) of false-positive reports (OR = 0.7 [0.6-0.8]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The PEC surveys should include children outside the target age to assess targeting efficiency, and pictures of both VAS and oral vaccines distributed during the same period should be shown during interviews to enhance reporting accuracy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0379572116666167","type":"journal-article","created":{"date-parts":[[2016,9,7]],"date-time":"2016-09-07T20:48:44Z","timestamp":1473281324000},"page":"529-543","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Factors Affecting the Validity of Coverage Survey Reports of Receipt of Vitamin A Supplements During Child Health Days in Southwestern Burkina Faso"],"prefix":"10.1177","volume":"37","author":[{"given":"C\u00e9saire T.","family":"Ou\u00e9draogo","sequence":"first","affiliation":[{"name":"Institut de Recherche en Sciences de la Sant\u00e9, Bobo-Dioulasso, Burkina Faso"},{"name":"Helen Keller International, Dakar, Senegal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elodie","family":"Becquey","sequence":"additional","affiliation":[{"name":"Helen Keller International, Dakar, Senegal"},{"name":"Department of Nutrition, University of California, Davis, CA, USA"},{"name":"International Food Policy Research Institute, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shelby E.","family":"Wilson","sequence":"additional","affiliation":[{"name":"Department of Nutrition, University of California, Davis, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lea","family":"Prince","sequence":"additional","affiliation":[{"name":"Department of Nutrition, University of California, Davis, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amadou","family":"Ou\u00e9draogo","sequence":"additional","affiliation":[{"name":"Institut de Recherche en Sciences de la Sant\u00e9, Bobo-Dioulasso, Burkina Faso"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"No\u00ebl","family":"Rouamba","sequence":"additional","affiliation":[{"name":"Institut de Recherche en Sciences de la Sant\u00e9, Bobo-Dioulasso, Burkina Faso"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Bosco","family":"Ou\u00e9draogo","sequence":"additional","affiliation":[{"name":"Institut de Recherche en Sciences de la Sant\u00e9, Bobo-Dioulasso, Burkina Faso"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen A.","family":"Vosti","sequence":"additional","affiliation":[{"name":"Department of Nutrition, University of California, Davis, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth H.","family":"Brown","sequence":"additional","affiliation":[{"name":"Department of Nutrition, University of California, Davis, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonja Y.","family":"Hess","sequence":"additional","affiliation":[{"name":"Department of Nutrition, University of California, Davis, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,9,20]]},"reference":[{"key":"bibr1-0379572116666167","volume-title":"Global Prevalence of Vitamin A Deficiency in Populations at Risk 1995-2005.
