  • Translation, adaptation and validation of the SRI questionnaire: A cross-sectional survey including patients receiving long-term mechanical ventilation in Norway

Abstract

The aims of this study were to translate and adapt the Severe Respiratory Insufficiency (SRI) questionnaire into Norwegians and to test its reliability and validity.Data were collected from a cross-sectional survey and were linked to the Norwegian Registry of patients receiving long-term mechanical ventilation (LTMV). Of 193 potential participants, 127 responded to the SRI questionnaire. Reliability as measured with Cronbach's α varied between 0.68 and 0.88 for the subscales and was 0.94 for SRI-sum score. Construct validity was obtained with high correlations between subscales in SF-36 and SRI. The SRI questionnaire discriminated well between universally accepted clinical differences among categories of patients receiving LTMV by significant dissimilarities in SRI-sum score and SRI subscales. The Norwegian version of SRI has well-documented psychometric properties regarding reliability and validity. It might be used in clinical practice and in international studies for assessing health-related quality of life in patients receiving LTMV.
