Correction to: Psychometric properties of the Turkish version of modified Freedman questionnaire for sleep quality (Sleep and Biological Rhythms, (2022), 20, 4, (459-465), 10.1007/s41105-022-00389-2)

Abstract

One of the reliability analyses of the study is incorrectly labeled as “test-retest”. The appropriate term is “inter-rater reliability”. In the sentence beginning ‘The reliability of the questionnaire…’ in this article, the text ‘The stability of the questionnaire was assessed by the evaluation of the correlation between the questionnaire administered by two observers (researchers) 1 h apart.’ should have read ‘In order to test the inter-rater reliability of the questionnaire, the patients were administered the questionnaire twice by two observers 1 h apart.’.
