A VALIDATED KNOWLEDGE, ATTITUDES, AND PRACTICES QUESTIONNAIRE FOR CAREGIVERS OF CHILDREN WITH ASTHMA IN SOUTHERN VIETNAM
Main Article Content
Abstract
Background: Asthma is a chronic inflammatory airway disease with increasing prevalence, yet pediatric control rates remain low. Caregivers' knowledge, attitudes, and practices are crucial for effective asthma management. However, validated knowledge, attitudes, and practices scales using advanced statistical methods are limited in the Mekong Delta. Objectives: To develop and validate a knowledge, attitudes, and practices scale for caregivers of asthmatic children. Materials and methods: A cross-sectional study enrolled 260 primary caregivers of children aged 4-16 years with asthma at Can Tho City Children's Hospital from December 2024 to December 2025. Caregivers completed a standardized questionnaire covering sociodemographic characteristics and a 29-item KAP questionnaire. For scale development and validation, the sample was split into two equal subsamples using the Solomon method. Each domain of the knowledge, attitudes, and practices scale was first examined separately by exploratory factor analysis in subset 1, and the retained factor structure was then tested by confirmatory factor analysis in subset 2. Results: The mean age of caregivers of children with asthma was 38.32 ± 8.194 years. Exploratory factor analysis and confirmatory factor analysis eliminated 10 items, retaining 19 items with satisfactory psychometric properties. The Knowledge, Attitudes, and Practices domains achieved high composite reliability (CR = 0.875-0.940) and good convergent validity (AVE = 0.503-0.759). HTMT indices were <0.85, demonstrating good discriminant validity. All confirmatory factor analysis models showed good data fit. Conclusion: The 19-item knowledge, attitudes, and practices questionnaire demonstrated satisfactory validity and reliability, serving as a simple, concise, and highly feasible tool for rapid outpatient assessment. This instrument represents a practical and reliable tool for assessing caregiver knowledge, attitudes, and practices in both clinical and research settings.
