| Popis: | a b s t r a c t Objective: To evaluate the reliability and validity of the Spanish version of the Newcastle Asthma Knowl- edge Questionnaire (NAKQ) for determining asthma knowledge in teachers. Methods: Design and sample: A cross-sectional observational study in educational centers of A Coru ˜ na providing preschool, primary school and/or compulsory secondary education. Centers were selected by random sampling, stratified by ownership and educational level (24 centers, 864 teachers). A total of 537 (62.1%) teachers responded (precision, ±4%, confidence, 95%). Measurements: Age, sex, academic training, teaching experience, personal/family history of asthma, NAKQ. Analysis: Evaluation of internal consistency (Cronbach's alpha). Concurrent validity was determined by comparing scores of asthmatic teachers or with asthmatic relatives with teachers with no contact with asthma. Test-retest reliability was evaluated in 2 randomly selected centers by the kappa index, Bland-Altman method and intraclass correlation coefficient. Results: Mean score on the NAKQ was 15.7 ± 5.3 (median 17), correctly answering 50.6% of items. Cronbach's alpha coefficient was 0.824 (95% CI: 0.802-0.845). NAKQ score was higher in asthmatic teachers or with close asthmatic relatives (17.7 ± 3.3) than in teachers with distant asthmatic relatives (16.1 ± 5.4) and teachers without close contact with asthma (15.1 ± 5.6; P |
