Effect of Community-Based Cervical Cancer Self-Sampling Education on Cervical Cancer Screening Knowledge among Women in Nigeria

Abstract

Cervical cancer remains an important public health concern among women in Nigeria and is largely preventable through vaccination, regular screening, early detection, and appropriate treatment of precancerous lesions. However, participation in cervical cancer screening may be limited by inadequate knowledge, fear of the procedure, embarrassment, concerns about privacy, limited availability of screening services, geographical barriers, cost, and misconceptions about cervical cancer. Community-based cervical cancer self-sampling education provides an opportunity to introduce women to self-collected cervical samples as an alternative approach to conventional clinician-collected screening methods while providing information on screening eligibility, procedures, benefits, limitations, follow-up, and referral. Against this background, this study investigates the effect of community-based cervical cancer self-sampling education on cervical cancer screening knowledge among women in Nigeria. The study will be anchored on the Health Belief Model, Health Belief Model–based Self-Sampling Framework, and Social Ecological Model. The Health Belief Model explains how perceived susceptibility to cervical cancer, perceived severity, perceived benefits of screening, perceived barriers, and cues to action may influence women's understanding and acceptance of cervical cancer screening. The self-sampling framework emphasizes how knowledge, perceived convenience, privacy, acceptability, confidence, and understanding of self-collection procedures may influence women's engagement with self-sampling-based screening. The Social Ecological Model recognizes the influence of individual, interpersonal, community, healthcare, and environmental factors on access to and utilization of cervical cancer screening services. Collectively, these theoretical perspectives provide a suitable framework for explaining how community-based self-sampling education may influence cervical cancer screening knowledge among women in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise women of appropriate cervical cancer screening age residing in selected communities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, local government areas, communities, households, and eligible women. Community-based cervical cancer self-sampling education will be assessed using indicators such as frequency and duration of education sessions, educational content, explanation of self-sampling procedures, demonstration of sample collection where appropriate, information on screening eligibility, benefits and limitations of self-sampling, privacy and confidentiality information, use of educational materials, involvement of trained healthcare professionals, use of local languages, opportunities for questions and clarification, referral information, and follow-up education. Cervical cancer screening knowledge will be assessed using indicators such as knowledge of cervical cancer risk factors, human papillomavirus (HPV), signs and symptoms, prevention, HPV vaccination, recommended screening, self-sampling procedures, sample handling, interpretation of screening results, follow-up after abnormal results, treatment of precancerous lesions, and appropriate healthcare-seeking. Data will be collected using structured questionnaires, interviewer-administered cervical cancer knowledge assessment tools, health education attendance records, educational materials, self-sampling demonstration records where applicable, and relevant community health programme documents. Descriptive statistics will be used to summarize participants' characteristics, exposure to self-sampling education, and cervical cancer screening knowledge scores. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the effect of community-based cervical cancer self-sampling education on screening knowledge. Where a quasi-experimental design is adopted, knowledge scores before and after the educational intervention may be compared with those of a comparison group or community to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that community-based cervical cancer self-sampling education has a significant positive effect on cervical cancer screening knowledge among women in Nigeria. Women exposed to structured self-sampling education are expected to demonstrate greater knowledge of cervical cancer prevention, HPV infection, screening procedures, self-sample collection, and appropriate follow-up than women without comparable exposure. Community-based education may help reduce misconceptions and concerns related to embarrassment, privacy, discomfort, and the perceived complexity of screening. Demonstrations, visual materials, local-language explanations, and opportunities for questions may improve women's understanding and confidence in the self-sampling process. Education may also clarify that a self-collected sample does not eliminate the need for appropriate clinical evaluation and follow-up when indicated by the screening result. However, limited availability of approved self-sampling materials, inadequate training of health workers, cultural misconceptions, fear of cancer, low literacy, misinformation, language barriers, and weak referral systems may reduce effectiveness. The study therefore expects accessible, accurate, culturally appropriate, and professionally supported community-based self-sampling education to contribute significantly to improved cervical cancer screening knowledge among women in Nigeria. The study is expected to contribute to the literature on cervical cancer prevention, HPV screening, cervical cancer self-sampling, community health education, women's health, cancer screening knowledge, health literacy, preventive healthcare, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Primary Health Care Development Agency, state ministries of health, primary healthcare centres, cancer-control programmes, healthcare professionals, community health workers, women's organizations, development partners, and policymakers regarding strategies for improving knowledge of accessible cervical cancer screening approaches. The study will also provide evidence-based recommendations for integrating self-sampling education into community health programmes, training healthcare workers to provide accurate self-sampling information, developing culturally appropriate educational materials, using local languages, strengthening referral and follow-up systems, addressing misconceptions about HPV and cervical cancer, and improving access to appropriate cervical cancer screening services among women across Nigeria.
