Cross-cultural adaptation and validation of Lithuanian-NOSE scale

Purpose To evaluate validity and reliability of Lithuanian version of Nasal Obstruction Symptom Evaluation Scale (L-NOSE), designed for the assessment of nasal obstruction. Methods Cross-cultural adaptation of L-NOSE was accomplished according to generally accepted methodology. L- NOSE was tested for its reliability, validity, and responsiveness in the group of 50 septoplasty patients and 100 healthy volunteers’ controls. Results L- NOSE showed good internal consistency (Cronbach’s alpha coefficient 0.796 for test, 0.791 for retest, 0.792 for post-operative group, and 0.817 for control group) scores and high test–retest reliability ( r = 0.94, p
