Cross-cultural adaptation of a Spanish version of a previously validated HPV survey that evaluates dental students' knowledge, perception and clinical practices in Latin America.

BACKGROUND

The global incidence of oropharyngeal cancer (OPC) is increasing. Dental professionals play a key role in the detection of oral lesions that could lead to cancer. However, scientific-based HPV-OPC visual inspection guidelines are underdeveloped and HPV knowledge and awareness has been reported to be low among dental students and professionals. The present study adapted and performed pretesting of a multi-scale survey evaluating knowledge, perceptions, and clinical practices regarding HPV and HPV-OPC for Latin American Spanish-speaking populations.

METHODS

A previously developed questionnaire for English-speaking dental students was translated to Spanish. The questionnaire was administered to first year dental students at two Latin American universities with dental programs. Internal consistencies were measured using Cronbach Alpha. Analyses were conducted in SAS Version 9.4.

RESULTS

Data from a total of 114 students, a majority of the which were female (61%), and Hispanic/Latino(a)/Spanish (91%). The HPV, HPV-OPC, and HPV vaccine knowledge subscales demonstrated good internal consistency, the Cronbach's alpha was 0.83, 0.75, and 0.86 respectively. The Barriers subscale had a Cronbach's alpha of 0.93, showing excellent internal consistency. The Clinical Procedures subscale, focused on factors surrounding dental students' hypothetical clinical practice procedures, had a Cronbach's alpha of 0.86. The Scope of Practice scale had a Cronbach's alpha of 0.93.

CONCLUSIONS

Ultimately, this survey demonstrated reliability and applicability for the assessment of dental students' knowledge, perceptions, and clinical practices regarding HPV and HPV-OPC in Latin America.
