Despite potential differences between computer-based and conventional questionnaire delivery, studies have not evaluated the agreement between electronic and paper versions of the ESS. Given the widespread use of the ESS, a bias between results would present considerable data concerns. Thus, the aim of this study was to examine agreement between electronic and paper ESS responses in obstructive sleep apnoea (OSA).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Design<\/jats:title>\n                  <jats:p>We undertook a secondary analysis of baseline data from a randomised controlled trial (ANZCTR: ACTRN12611000847910).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Setting<\/jats:title>\n                  <jats:p>Data were collected in a tertiary sleep research laboratory located in Sydney, Australia.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Participants<\/jats:title>\n                  <jats:p>Data were analysed from 112 adult patients with OSA.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Measurements<\/jats:title>\n                  <jats:p>Patients were given the English version of the ESS as part of a battery of sleep laboratory questionnaires.
