Acceptability and validity of HPV self-sampling for cervical cancer screening among women living in different ecological settings in India

India records one fifth of global cervical cancer burden. Unlike human papillomavirus (HPV) self-sampling, other screening methods may cause discomfort and embarrassment. This study aimed to investigate attitudes, acceptability, barriers, predictors, effective modality of instructions, and validity of HPV self-sampling among Indian women residing in varied settings and different literacy levels. This is community-based interventional study among Indian women 30-55 years, residing in urban slums (500), urban non-slums (500), and rural (600) settings with varied washroom facilities and privacy, to collect self-samples. Each group was subdivided into two arms; in one women received education with pamphlets and other with health education program (HEP). Study involved enlisting eligibles, obtaining informed consents and conducting personal interviews to collect baseline data. Self-samplers were distributed with instructions (pictorial pamphlets in one group and HEP in other) regarding usage, storage and return. Willingness to use self-samplers, refusals, experiences, and so forth were captured. Post-intervention knowledge, attitudes, practices was recorded. HPV reports were distributed. Women with positive result on either test were offered further management. Acceptance rate of self-sampling was 99.2%, 97%, and 98.8% and HPV positivity was 7%, 7.8%, and 8.5%, respectively among urban non-slum, urban slum and rural women. Agreement rate between health personnel collected and self-collected samples was 96.5% in pamphlet and 93.2% in HEP arm. Major barriers of self-sampling were lack of confidence about performing self-test correctly, fear that test would be painful and anxiety about test results. HPV self-sampling has good acceptability among Indian women and good agreement with health personnel collected samples.
