| Sumario: | Aim: A study was made of the psychometric characteristics of the modified Freedman questionnaire to assess sleep in critical patients. Design: A psychometric study was carried out, with content validity being explored by a group of experts, and internal consistency based on Cronbach's alpha coefficient. Factor analysis was performed to explore construct validity, and stability was assessed by test-retest analysis. Setting: The Department of Intensive Care Medicine of a reference hospital. Participants: Patients admitted between 23 February 2016 and 20 December 2017. Interventions: Questionnaire administration. Variables: Items of the modified Freedman questionnaire. Results: Item relevance and definition yielded scores > 3 (Likert scale maximum =4). Cronbach's alpha showed a global value of 0.933. The intraclass correlation index was '8.7s for most of the items of the questionnaire. Factor analysis allowed the detection of specific associations between the studied variables and the four factors. Conclusions: The modified Freedman questionnaire showed good psychometric characteristics. It may be a reliable instrument for assessing the quality of sleep in critically ill patients, as well as the environmental factors. (C) 2019 Elsevier Espana, S.L.U. y SEMICYUC.
