ABSTRACT
Objective:To compare the clinical value of visual analogue scale （VAS）, Lebel scale and total nasal symptom scores （TNSS） in evaluating nasal allergen provocation test （NAPT）. Methods:A total of 151 patients suspected of allergic rhinitis admitted to the Department of Otolaryngology-Head and Neck Surgery of our hospital from April 2020 to September 2020 were included, of which 76 were positive for house dust mites and 75 were negative for allergens. Nasal airway resistance（NAR） was measured by active anterior nasal manometry. Nasal symptoms were evaluated by VAS, Lebel and TNSS. House dust mite allergen was used for NAPT by spray method. An increase≥40% in NAR was used as the gold standard for objective evaluation of NAPT. ROC curves of VAS, Lebel and TNSS were drawn to compare the evaluation effectiveness of different subjective evaluation methods, and the optimal critical point of each ROC curve was obtained. Results:With NAR increased by ≥40% as the gold standard, the area under ROC curve of VAS was 0.884, and the sensitivity and specificity were 97.75% and 80.65%, respectively. The area under ROC curve of Lebel was 0.773, and the sensitivity and specificity were 68.54% and 75.81%, respectively. The area under ROC curve of TNSS was 0.792, and the sensitivity and specificity were 68.54% and 79.03%, respectively. There was no significant difference between Lebel and TNSS（P>0.05）. The VAS differed significantly from Lebel and TNSS（P<0.05）. The Kappa values of VAS, Lebel, TNSS and NAR were 0.803, 0.432 and 0.459, respectively. Conclusion:The VAS, Lebel, TNSS subjective scale and NAR are consistent in evaluating the efficacy of NAPT, with the VAS assessment showing highest consistency with NAR. As objective assessment instruments are not widely used in China, subjective assessment method could be adopted to evaluate the efficacy of NAPT in clinical practice, and VAS scale is recommended as a priority.

El objetivo de este estudio es confirmar las características psicométricas de la Escala Subjetiva de Carga Mental de Trabajo (ESCAM) en trabajadores sanitarios de hospitales chilenos. Participaron en este estudio 379 trabajadores de tres hospitales. Los instrumentos utilizados fueron: (a) ESCAM y (b) el cuestionario SUSESO-ISTAS 21. Los resultados indican que ESCAM se estructura en cinco dimensiones: Demandas cognitivas y complejidad de la tarea, Características de la tarea, Organización temporal, Ritmo de trabajo y Consecuencias para la salud. Asimismo, se observan correlaciones significativas entre la puntuación total de ESCAM y sus dimensiones con los factores de SUSESO-ISTAS 21. Además, se comprobó la validez de la escala mediante el análisis de perfiles de carga mental con diferentes grupos profesionales.
The aim of this study is to confirm the psychometric characteristics of the Subjective Mental Workload Scale (SCAM) in health workers of Chilean Hospitals. The instruments used were: (1) SCAM; (2) questionnaire SUSESO-ISTAS 21. The sample was composed of 379 workers from three hospitals. The findings showed that SCAM is structured in five dimensions: Cognitive demands and task complexity, Task characteristics, Temporal organization, Work rate, and Health consequences. Likewise, significant correlations between overall score of SCAM and its dimensions with the SUSESO-ISTAS 21 factors were found. Also, scale validity was verified through mental workload profiles with different professional groups.
