Validation of the Hungarian version of the SRI Questionnaire

Abstract

Background: Home mechanical ventilation is a reliable treatment for patients suffering from chronic respiratory failure, improving survival and quality of life. Prevalence has been increasing worldwide as a result of evolving technical possibilities, telemedicine and improving national guidelines. Projects to establish a national guideline and registry for patients treated with home mechanical ventilation are currently under way in Hungary and our aim was to validate a quality of life questionnaire suited for evaluation and follow up in this specific patient group. The Severe Respiratory Insufficiency Questionnaire (SRI) is a quality of life tool designed to evaluate patients receiving home mechanical ventilation and has been validated both in patient groups receiving invasive and noninvasive ventilation. Methods: The Hungarian version of the SRI was created using the translation-backtranslation method, which was then tested for validity, viability and reliability in a cohort involving patients from three centers, receiving long-term home mechanical ventilation for chronic respiratory failure through an invasive or noninvasive interface. Patient data was collected (demographic data, lung function test, arterial blood gas, ventilation settings) and quality of life was measured with the previously validated SF-36 and newly created Hungarian SRI Questionnaires at two time points. Results: One hundred four patients receiving home mechanical ventilation were enrolled. The time to complete the SRI Questionnaire was 8.6 (±3.1) minutes, 69.2% questionnaires were self-administered. Exploratory factor analysis explained 73.8% of the variance of the questionnaire, but resulted in 13 scales. We found correlations between the SRI subscale scores to corresponding scales of the previously validated general quality of life survey SF-36. The Cronbach alpha coefficient was 0.928 for the Summary Scale of the SRI Questionnaire, proving high internal consistency. Reproducibility was high for most scales, resulting in a high overall correlation for the summary score (0.877, p < 0.001). Conclusions: The Hungarian version of the SRI Questionnaire is a viable, valid, reliable and reproduceable quality of life tool applicable for patients treated with home mechanical ventilation.

Home mechanical ventilation: quality of life patterns after six months of treatment

“…The main limitation of our study is the sample size that might be considered small; however previously published studies on HMV patients utilized similar sample sizes [11,13,14,21,23]. Our study was a single center, prospective HRQL change investigation under optimized care using the SRI Questionnaire, providing valuable "real-life" information on a mixed case population previously not extensively described in the literature.…”

“…The purpose of this prospective observational follow-up study was to evaluate, using the Hungarian validated version of the Severe Respiratory Insufficiency Questionnaire [21], HRQL change 6 months after the initiation of home mechanical ventilation in patients suffering from chronic respiratory failure, and identify possible factors influencing said changes. We enrolled patients diagnosed with chronic respiratory failure in need for long term mechanical ventilation, who were treated through the Semmelweis University Home Mechanical Ventilation Program from January 2014 to December 2018.…”

“…The SRI Questionnaire has been validated in several different conditions and has been proven to be a superior HRQL evaluation tool for patients receiving home mechanical ventilation [9,13]. The questionnaire has been used to evaluate HRQL in both invasively and noninvasively ventilated patients and has been validated in several different languages, including Hungarian [13][14][15][16][17][18][19][20][21].…”

Validation of the Reliability of Machine Translation for a Medical Article From Japanese to English Using DeepL Translator

“…MT using DeepL Translator was performed for each section. The automatically translated English text was back-translated into Japanese by translators [ 9 , 10 ]. The method of the back translation was as follows.…”

Validation of the Polish version of Severe Respiratory Insufficiency Questionnaire

“…The construct validity was confirmed via a factor analysis, indicating one summary scale that accounted for 59.8% of the variance. The SRI has already been translated and validated in several languages, including Spanish [9], English [10], Dutch [11], French [12], Norwegian [13], Finnish [14], Portuguese [15], Greek [16], Hungarian [17], Chinese [18] and Japanese [19] and the process is still ongoing. Almost 20 years after its creation, the SRI has become an international standard assessment tool for HRQL.…”
