Translation, cross-cultural adaptation, and validation of the sino-nasal outcome test (SNOT)-22 for Lithuanian patients

Abstract

The objective of this study was to perform translation, cross-cultural adaptation, and validation of the SNOT-22 in the Lithuanian language. This is a prospective case-control study. The study was conducted at the University clinic. The sino-nasal outcome test 22 (SNOT-22) was translated into the Lithuanian language; the pilot study involved 34 patients, the test-retest group consisted of 34 patients with chronic rhinosinusitis (CRS), and the control group of 115 patients with no CRS complaints; 36 patients were evaluated before surgery and 3 months after surgery. The results showed a good internal correlation with Cronbach's alpha-0.89 in the initial test, and 0.93 in the retest; both values suggesting good internal consistency within the SNOT-22. Pearson's correlation coefficient was 0.72 (p < 0.001), revealing good correlation between the initial scores and the retests scores. Our sample of healthy individuals had a median score of 12 points, and the instrument was capable of differentiating between the healthy and the patient group, demonstrating its validity (p < 0.0001). The statistically significant reduction in the post-operative scores, vis-à-vis pre-operative values, demonstrates the responsiveness of the instrument. The minimally important difference was 13 points in the SNOT-22 score. The Lithuanian version of the SNOT-22 is a valid instrument for assessing patients with CRS. It demonstrated good internal consistency, reproducibility, validity, and responsiveness.

Validation and cross‐cultural adaptation of the arabic version of the nasal obstruction symptom evaluation scale

“…Responsiveness for change is the capacity of the questionnaire to detect changes over time in health status . In our study, the Wilcoxon signed rank test was used to compare the mean score for each question and the total score of the A‐NOSE scale before and 3 months after septal surgery, with strong statistical difference for each question and the total score, confirming the previous suggestion of Stewart et al, that the brevity of the NOSE scale does not detract from its sensitivity.…”

“…Discriminatory validity of the measure is the ability of the questionnaire to distinguish between the patients and healthy individuals who do not suffer from the disease being studied . In our study, comparing the mean score of the A‐NOSE scale for each item of the scale and for the total score between both groups was done using the Mann‐Whitney test, where there was a highly significant statistical difference among those means for each item of the scale and for the total score between the patients and the controls, assuring the ability of the A‐NOSE scale to distinguish between patients and healthy individuals.…”

“…Moreover, the SNOT22 is extremely important when surgical treatment is a consideration as it can assist in estimating the effect of surgery and the possibility of achieving a realistic outcome. As a result of its popularity, the SNOT22 questionnaire was translated and culturally adapted from English to other languages [12][13][14][15][16][17][21][22][23][24][25][26][27] ; however, a Russian version has yet to be reported.…”

Reliability and Validity of Turkish Nose Obstruction Symptom Evaluation (NOSE) Scale

“…Internal consistency refers to the way in which the items within an instrument relate to each other (11). In the original study by Stewart et al (3), the overall Cronbach's alpha coefficient was 0.785, while in Marro et al 's (4) and Mozzanica et al 's (6) studies it was 0.86 and 0.81, respectively.…”
