Validation of the Chinese Version of the Sinus and Nasal Quality of Life Survey (SN-5)
Condition: Chronic Rhinosinusitis
Study type: Observational

Summary: 
      The purpose of our study was to validate the Chinese version of the Sinus and Nasal Quality
      of Life Survey (SN-5)and correlation with the incidence of pediatric obstructive sleep apnea
      and asthma.

      The study will enroll pediatric patients of rhino-sinusitis and their parents to finish
      Questionnaire 1, including Chinese version of SN-5, visual analogue scale (VAS), Pediatric
      allergy disease Pediatric Allergic Disease Quality of Life Questionnaire (PADQLQ), OSA-18
      quality of Life Survey, and asthma-diagnostic questionnaire . Some patients re-tested SN-5 in
      1 week later. After four weeks, participants finish these questionnaire 2, including SN-5,
      VAS, and PADQLQ. In addition, the author will invite health children without rhino-sinusitis
      disease and their parents to fill in Questionnaire 1. The Chinese version of SN-5 will be
      validated to establish its reliability and validity.

      From December 2016 to December 2017, healthy volunteers and children with persistent
      sinonasal symptoms were enrolled. Guardians of the participants completed the SN-5, a visual
      analog scale (VAS) of nasal symptoms, and the Obstructive Sleep Apnea-18 (OSA-18) ; the
      responses were used to assess internal consistency, discriminant validity, and treatment
      responsiveness. A nontreatment group was administered the SN-5 1 week later to assess
      test-retest reliability.
    

Intervention name(s): Sinus and nasal quality of life survey questionnaire (SN-5)
Intervention type(s): Other
Intervention description(s): The SN-5 consists of five questions on a 7-point scale that assesses the frequency of the following symptoms: (1) nasal obstruction, (2) sinus infection, (3) allergies, (4) emotional distress, and (5) activity limitations. The scoring system is as follows: 1 indicates "none of the time," 2 indicating "hardly any time at all," 3 indicates "a small part of the time," 4 indicates "some of the time," 5 indicates "a good part of the time," 6 indicates "most of the time," and 7 indicates "all of the time." Higher scores indicate more severe sinonasal symptoms. One item from a global faces scale scored from 0 to 10 is used to evaluate overall QoL related to nasal or sinus disease. Higher scores on this scale indicate a less severe impact of nasal or sinus disease. The scores from the first five items (1-7 each)
Observational model: Case-Control
Time perspective: Prospective
Sampling method: Probability Sample

        Rhinosinusitis patients were recruited from pediatric clinics practicing Western or Chinese
