Impact of a community-based educational intervention on knowledge regarding cancer warning signs and screening methods among rural adults: A pre-experimental study

Introduction: Cancer is a major health problem. Early detection depends on recognition of warning signs and screening. Community-based education may improve knowledge and promote appropriate health-seeking practices.Aim and Objectives: The aim and objective of this study was to evaluate the impact of an educational intervention programme on knowledge regarding cancer warning signs and screening methods among adults residing in a community of Rajavoor, Kanyakumari District, Tamil Nadu.Materials and Methods: A quantitative, pre-experimental, one-group pre-test and post-test design was used. Thirty adults were sampled convenience sampling technique. Data were collected using a standardized 20-item knowledge questionnaire and demographics. Each correct answer received one mark. Following the pre-test, participants received a 45-minute educational intervention. Descriptive and inferential statistics were used. Pre-test and post-test scores were compared using the paired t-test, while associations between post-test knowledge and demographic variables were examined using the chi-square test.Results: In the pre-test, 8 participants (27%) had inadequate knowledge, 22 (73%) had moderate knowledge and none had adequate knowledge. Following the intervention, 19 (63%) had adequate knowledge, 11 (37%) had moderate knowledge and none had inadequate knowledge. The mean knowledge score increased from 8.53 ± 2.27 to 14.40 ± 2.27, with a mean difference of 5.87 and a significant paired t-value of 13.53 (p < 0.05). No significant association was found between demographic variables and post-test knowledge.Conclusion: The intervention improved knowledge regarding cancer warning signs and screening methods among rural adults. Community-based cancer education should be strengthened to support early detection.
