A cross-sectional study on the acceptability of self-collection for HPV testing among women in rural China

Objective To assess the acceptability of using self-collection as a method of sampling for human papilloma virus testing in rural China. Methods 174 women from the national cervical cancer screening programme in Xiangyuan County, China, were enrolled in our study and underwent self-collection, clinician collection, colposcopy examination and were administered questionnaire. The questionnaire assessed the patients' preference and acceptability of collection method. Results The mean overall acceptability score for self-collection, although significantly less than the overall score for clinician collection (p<0.01), still is well above 4 (4.33 of 5), indicating high acceptability. The acceptability scores for self-collection and clinician collection were not significantly different on scales measuring comfort and convenience (p>0.05). The scores were significantly lower for self-collection on scales measuring trust, ability to collect specimen and perceived effects of testing compared with clinician collection (p<0.01). 74% of participants preferred clinician collection, and of these participants, 86% preferred it because they thought the results were more accurate. Conclusions The study shows that self-collection was highly acceptable and that self-collection and clinician collection were equally comfortable and convenient; however, the participants still preferred clinician collection because of lack of trust in the results of self-collection. This indicates that self-collection is an acceptable potential method for screening but education programmes about the validity of self-collection that target general population may be needed prior to implementation.
