Acceptability and Preference for Human Papilloma Virus Self-Sampling among Thai Women Attending National Cancer Institute.

Background: Cervical cancer screening is an important public health strategy to reduce cervical cancer incidence and mortality. Human papillomavirus (HPV) self-sampling is the alternative method that can potentially increase participation in cervical cancer screening. This study aimed to evaluate the acceptability of HPV self-sampling as a primary cervical cancer screening among Thai women.

Methods: A cross-sectional study was conducted at National Cancer Institute, Thailand, between March and September 2021. Eligible women were invited to collect their own samples with a vaginal cotton swab for cervical screening. The data on demographics, acceptability, and preference for HPV self-sampling were collected via a self-administered questionnaire. A Likert scale was used to assess the response of self-sampling acceptability. The multivariable logistic regression determined factors that influence preference for HPV self-sampling.

Results: A total of 265 participants were recruited. Over 70% agreed that self-sampling was easy, less embarrassing, and not painful. They also felt confident in their ability to self-sample correctly and would recommend this method to a friend or relative. For their next screening round, 66.4% preferred self-sampling whereas 33.6% preferred clinician-collected samples as routine screening. The factors that influence preference for self-sampling were age, marital status, feeling less embarrassed, and confidence in performing the tests.

Conclusions: Most of the study participants accepted HPV self-sampling. This suggests that the self-sampling method will be an additional option to increase cervical cancer screening coverage which leads to improving the effectiveness of the national program.
