“…Similar to the findings in the original study by Hopkins, the German SNOT-22 demonstrated an excellent correlation to the single global disease-specific question (p < 0.0001), further supporting the criterion validity of the questionnaire. Similar to previous reports, but unlike the Austrian validation, no significant correlation could be found between the SNOT-22 and the Lund-Mackay scores [9,12,31]. This underlines the fact, that it is the patient with his or her perceived impairment that should be treated and not the radiological image.…”

“…This finding is comparable to other existing language translations, as the mean score for Cronbach's alpha of 15 versions of the SNOT-22 is 0.88 with a minimum of 0.8 in the Arabic [10] and a maximum of 0.96 in the Moroccan translation [30]. A recent publication from Austria which validated but did not translate or adapt the German SNOT-22, also showed a comparable result of 0.93 for internal consistency [31]. An overview of the results of the different SNOT-22 translations is indicated in Table 2.…”

“…The differences in measurements in the different countries could be explained by several demographic confounders and comorbidities [35] or could indicate a cultural difference in the perceived impairment in quality of life due to the disease. The slightly weaker results of the Austrian validation of the German SNOT-22 in terms of validity and responsiveness could also be due to demographic confounders or to the fact that the German spoken in Austria is only similar to the German spoken in Germany, as the authors themselves admit [31]. Similar to the findings in the original study by Hopkins, the German SNOT-22 demonstrated an excellent correlation to the single global disease-specific question (p < 0.0001), further supporting the criterion validity of the questionnaire.…”

Purpose Chronic rhinosinusitis (CRS) is a common condition associated with a significant reduction of the health-related quality of life. One of the most widely used assessment tools in CRS is the disease-specific, health-related questionnaire SNOT-22. The aim of this study was to translate and validate the SNOT-22 into the German language. Methods The questionnaire was translated using the forward–backward translation technique. After the translation its reliability, validity, and sensitivity were evaluated. For this purpose, the questionnaire was completed by patients diagnosed with CRS before, 3 months and 1 year after endoscopic sinus surgery and by healthy individuals as controls at three university hospitals in Germany. The individual scores of the questionnaire before surgery was correlated with the Lund–Mackay score as well as a global disease-specific question. Results A total of 139 CRS patients and 31 healthy individuals participated in the study. Internal consistency at all timepoints was very good, with Cronbach’s alpha scores of 0.897, 0.941, and 0.945. The questionnaire was able to discriminate between CRS patients and control subjects (p < 0.0001) and scores improved significantly 3 month and 1 year after sinus surgery (p < 0.0001), indicating a good test–retest reliability, validity, and responsiveness. A significant correlation to the single global disease-specific question could be found (p < 0.0001), but no correlation with the Lund–Mackay score. Conclusion The German Version of the SNOT-22 is a reliable, valid, and sensitive instrument for measuring health-related quality of life in patients with CRS. It can be recommended for clinical practice and outcome research for German-speaking patients.

“…In a recent survey among head and neck surgeons, more than half reported that they do not systematically record functional outcomes, in part because the instruments are too cumbersome and the time required is too long. In contrast to other common otorhinolaryngologic diseases such as chronic rhinosinusitis [ 25 , 26 ], simple, clinically applicable instruments for recording HNC-related basic physical and mental functions are rare [ 8 , 27 ]. The aim of this study was to develop and validate an instrument to assess a basic functional status of HNC patients at oncological follow-up visits.…”

Head and neck cancer (HNC) and its treatment can lead to various functional impairments. We developed and validated an instrument for rapid physician-rated assessment of basic functional outcomes in HNC patients. HNC-relevant functional domains were identified through a literature review and assigned to verbal ratings based on observable criteria. The instrument draft was subjected to systematic expert review to assess its face and content validity. Finally, the empirical validity, reliability, and responsiveness of the expert-adapted Functional Integrity in Head and Neck Cancer (HNC-FIT) scales were assessed in healthy controls and in HNC patients. A matrix of the 6 functional domains of oral food intake, respiration, speech, pain, mood, and neck and shoulder mobility was created, each with 5 verbal rating levels. Face and content validity levels of the HNC-FIT scales were judged to be adequate by 17 experts. In 37 control subjects, 24 patients with HNC before treatment, and in 60 HNC patients after treatment, the HNC-FIT ratings in the 3 groups behaved as expected and functional domains correlated closely with the outcome of corresponding scales of the EORTC-HN35-QoL questionnaire, indicating good construct and criterion validity. Interrater reliability (rICC) was ≥0.9 for all functional domains and retest reliability (rICC) was ≥0.93 for all domains except mood (rICC = 0.71). The treatment effect size (eta-square) as a measure of responsiveness was ≥0.15 (p < 0.01) for fall domains except for breathing and neck and shoulder mobility. The median HNC-FIT scale completion time was 1 min 17 s. The HNC-FIT scale is a rapid tool for physician-rated assessment of functional outcomes in HNC patients with good validity, reliability, and responsiveness.

BackgroundThe chronic rhinosinusitis patient‐reported outcome (CRS‐PRO) is a recently published disease‐specific questionnaire designed for CRS patients, with fewer entries and ease of completion. This study aimed to translate the CRS‐PRO questionnaire into Chinese and assess its reliability, validity, and responsiveness to provide Chinese patients with a more concise and efficient subjective assessment instrument.MethodsThe Chinese version of the CRS‐PRO was created through forward‐backward translations and cultural adaptation. Here, 168 CRS patients (118 patients CRS with nasal polyps [CRSwNP] and 50 patients with CRS without nasal polyps [CRSsNP]) and 43 healthy individuals were enrolled. All participants completed the CRS‐PRO, 22‐item Sinonasal Outcome Test (SNOT‐22), and EuroQol five dimensions questionnaire (EQ‐5D) questionnaires preoperatively as well as 3 and 6 months after surgery.ResultsThe Chinese version of the CRS‐PRO demonstrated good internal consistency, with a Cronbach's α of 0.813. It also exhibited a higher criterion validity (r = 0.65, p < 0.05) than the SNOT‐22. A moderate association was found between the CRS‐PRO and objective indicators such as the Lund–Mackay and endoscopic scores. Furthermore, the CRS‐PRO, like the SNOT‐22, could clearly distinguish CRS patients from healthy subjects (p < 0.01), as well as between the CRSwNP and CRSsNP subtypes (p < 0.01). Additionally, changes in the CRS‐PRO exhibited a larger effect size compared to changes in the SNOT‐22 (Cohen's d = 1.05 and 0.93 vs. 0.71 and 0.90 for 3 and 6 months, respectively, all p < 0.01).ConclusionsThe Chinese version of the CRS‐PRO is a concise, reliable, and responsive instrument that can be utilized as a novel subjective evaluation tool for future clinical practice.
