*
Separate models are presented at three time points for five outcome variables: overall acceptability and subscales measuring trust, confidence, comfort and perceived effects of testing (15 models in total). Only significant variables are shown.
†
Ever prescribed a vaginal medication.
‡
Concordance between self-test results and clinician-test results.
