Insights

The Chinese version of the Pediatric Asthma Symptoms Scale (C-PASS) is a reliable and valid tool for assessing asthma severity in Taiwanese children. This scale aids clinicians in identifying appropriate interventions for pediatric asthma patients.

Area of Science:

  • Pediatric Pulmonology
  • Psychometrics
  • Clinical Assessment Tools

Background:

  • Assessing pediatric asthma severity is challenging due to a lack of validated home-based instruments.
  • Asthma severity is a crucial construct for understanding varied child responses to their condition.
  • A reliable and valid tool is needed for accurate severity assessment in home settings.

Purpose of the Study:

  • To examine the psychometric properties of the Chinese version of the Pediatric Asthma Symptoms Scale (C-PASS).
  • To validate the C-PASS for use in an ethnic Chinese population in Taiwan.
  • To establish the reliability and validity of C-PASS for assessing pediatric asthma severity.

Main Methods:

  • Translation consistency assessed by five master's-prepared pediatric nurses.
  • Evaluation of internal consistency, split-half reliability, content validity, criterion-related validity, and construct validity.
  • Data collected from mothers of 70 Taiwanese children (mean age 8.35 years) using the 8-item C-PASS.

Main Results:

  • High internal consistency (Cronbach's alpha = .87) and Guttman split-half reliability (.87) were observed.
  • Content Validity Index (CVI) exceeded .80, supporting content validity.
  • Significant correlation (r = .273, p = .022) with concurrent measures supported criterion-related validity; factor analysis revealed two dimensions accounting for 67.92% of variance.

Conclusions:

  • The Chinese version of the Pediatric Asthma Symptoms Scale (C-PASS) is a reliable and valid instrument for Taiwanese children with asthma.
  • C-PASS can be effectively used in clinical practice to identify asthma severity levels requiring intervention.
  • This validated tool addresses the need for accurate pediatric asthma severity assessment in home environments.

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:
Classification of Asthma
Asthma III: Clinical Manifestations01:13

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
