Preferences for online or in-person STI testing vary by where a person lives and their cultural background: a survey of young Australians.

Objectives: The objectives are to explore the acceptability of online sexually transmitted infection (STI) testing services among young Australians (16-29 years) and how this may vary between sociodemographic populations.

Methods: A cross-sectional, online survey (using both closed and open-ended questions) of Australians aged 16-29 years. Of 905 participants, 781 (86%) responded to the question on preference for online versus in-person STI testing and are included in this analysis. Logistic regression was used to identify sociodemographic factors associated with STI testing preferences (online vs in-person). Adjusted ORs (AOR) are reported for each sociodemographic factor. Content analysis was used to code open-ended responses explaining the reasons for the participant's testing preference.

Results: Among the participants, 75% (588/781) preferred online testing over in-person testing. 677 (87%) provided reasons for their preference in an associated, open-ended question. Multivariable analysis found that the odds of preferring online services were significantly increased for those living in rural compared with metropolitan areas (AOR=1.7, 1.0-2.9). The odds of preferring online testing over in-person testing were significantly decreased for those of Asian descent (AOR=0.4, 0.2-0.6) and for those who reported having previously tested for an STI (0.6, 0.4-0.9). Convenience and privacy were key factors from the content analysis underlining preferences for online testing services but tended to be voiced by participants with certain sociodemographic characteristics (ie, men who have sex with men and older participants). Factors related to trust and convenience underscored preferences related to in-person testing.

Conclusions: It is clear that there is considerable interest among young people in using online STI testing, but it may not be right for all individuals. Understanding what factors associated with online testing are valued by young users can help inform marketing strategies that highlight these value propositions in their messaging. Further research is needed to engage young people and develop a high-quality, usable online service.
