Validating knowledge and attitude for cervical cancer screening among rural women: A rasch and factor analysis approach

Objectives This study aimed to validate a questionnaire tool for assessing knowledge and attitude toward cervical cancer screening among rural women using both Factor and Rasch analysis approaches. Material and Methods A cross-sectional study was conducted among 160 rural women in Tamil Nadu. Factor analysis was performed on all 160 responses, while Rasch analysis used a subset of 80. The questionnaire included 12 items addressing cervical cancer risk factors, screening methods, and attitudes toward screening. Content was culturally adapted and validated through expert consultation and pilot testing. Results Factor analysis revealed a multidimensional structure underlying knowledge and attitudes, identifying key latent factors influencing screening behavior. Rasch analysis demonstrated strong item fit, internal consistency, and reliable person separation indices, validating the tool's psychometric robustness. Conclusion The questionnaire showed strong validity and reliability in assessing knowledge and attitudes toward cervical cancer screening. Findings support its use for public health planning and interventions aimed at enhancing awareness, addressing attitudinal barriers, and improving screening participation in underserved rural communities.
