Turkish adaptation of the post-intensive care syndrome questionnaire: A validity and reliability study

Abstract

Aim: In this study, we aimed to adapt and determine the psychometric properties of the Turkish version of the Post-Intensive Care Syndrome Questionnaire. Material and Methods: This methodological study was conducted with 120 patients discharged from different intensive care units in Turkey between May 2020 and June 2021. Data were collected using a Socio-Demographic Form, Post-Intensive Care Syndrome Questionnaire, the General Health Poll, and the Pittsburgh Sleep Quality Index. Language and content validity were studied to adapt the scale. The construct validity was analyzed using confirmatory factor analysis. Reliability was evaluated with Cronbach's alpha coefficient, item-total score correlation, and similar measurement tools. Results: As a result of confirmatory factor analysis, the 10-item and 3-factor structure of the scale was determined. The factor loads of the items were between 0.60 and 0.90. Cronbach's alpha was determined as 0.94. There was a strong positive correlation between scales. Discussion: The Turkish version of the Post-Intensive Care Syndrome Questionnaire is a valid and reliable instrument for the Turkish population.
