Changes in Knowledge, Attitudes, and Practices Following a Structured Community-Based Dengue Awareness Programme: A Prospective Pre–Post Study in Kolkata, India

This community-based study evaluated the effect of a structured 12-week dengue awareness programme on Knowledge, Attitude, and Practice (KAP) among 385 adults from Wards 57 and 58 of Tangra, Kolkata. Participants were assessed before and after the programme using a 38-item researcher-administered KAP questionnaire. Total KAP scores improved substantially following the intervention, with the median score increasing from 17 to 25 and a large within-participant effect (r = 0.86; p < 0.001). Improvements were observed across all three KAP domains, while education was the most consistent predictor of greater improvement, and socioeconomic status was additionally associated with Practice. The findings support the potential value of structured community-based dengue awareness programmes, while highlighting the need for context-sensitive communication and further evaluation using controlled designs and validated KAP instruments.本项基于社区的研究针对印度加尔各答唐格拉区57与58街坊的385名成年人，评估了为期12周的结构化登革热认知宣教项目对其知识、态度、实践（Knowledge, Attitude, and Practice, KAP）的影响。研究人员采用由研究者施测的38条目KAP问卷，在项目实施前后对受试者开展评估。干预后受试者的KAP总分显著提升，中位数从17分升至25分，受试者内部效应量较大（r=0.86；p<0.001）。三个KAP维度均观察到改善情况，其中受教育程度是提升幅度最一致的预测因素，社会经济地位则与实践维度得分存在关联。本研究结果证实了结构化社区登革热认知宣教项目的潜在应用价值，同时强调需开展贴合当地情境的沟通工作，并采用对照研究设计与经过验证的KAP评估工具开展进一步评估。
