Validation of a clinical instrument for measuring the severity of acute bronchitis in children – the BSS-ped

  • Background: There are no validated standardised clinical procedures for severity measurement of acute bronchitis in children. The "BSS-ped", a short version of the physician-rated assessment scale BSS (Bronchitis Severity Scale), can fill this gap, if it is valid. Objective: To examine the scale´s validity. Methods: Investigations were planned according to classical clinical-psychometric validity criteria including a formal competence evaluation of the scale´s authors and statistical analyses of data from 78 patients aged 1-6 and diagnosed with "acute bronchitis". Cross-validation was provided by analysis of data from 70 children with matching age, sex and diagnosis. All children were examined three times (day 0, 3-5 and 7) using the BSS-ped in addition to other clinical and psychometric monitoring procedures. Results: The evidently high level of expertise of the scale’s authors substantiates pronounced content validity and relevance of the BSS-ped and its items. The validity criterion, i.e. to reflect the unidimensional severity of acute bronchitis and its change using the BSS-ped score, was fulfilled. There were substantial correlations with other scales measuring the current health-related quality of life, as well as satisfaction and success of treatment. Severity change prognoses for acute bronchitis under placebo and an active substance were correct. The BSS-ped was found to be a feasible instrument because it can be repeated at short intervals (minute range) without any special technical aids or extended training. Conclusion: The BSS-ped is a valid procedure for measuring the severity of acute bronchitis in children.
