Efficacy of pedagogical approaches in promoting hepatitis C knowledge and self-efficacy among men living with HIV: A randomized controlled trial
ABSTRACT
Background:
Hepatitis C virus (HCV) transmission rates are high among men who have sex with men (MSM) living with human immunodeficiency virus (HIV), a group with low awareness and limited skills in HCV prevention. However, few educational interventions are specifically designed for this population.
Objective:
This study aimed to evaluate the effectiveness of digital educational interventions on HCV prevention knowledge and self-efficacy among MSM living with HIV.
Methods:
PWH who are MSM were randomly assigned in a 1:1:1 ratio to receive three different HCV educational modalities using serious game interventions (SG), web browsing (WB), or verbal/printed pamphlet (VP). The participants underwent a uniformed questionnaire interview to assess their knowledge and self-efficacy in preventing HCV infection at pre-intervention. The evaluations were repeated 1-week post-intervention and 12-week follow-up after randomization.
Results:
207 PWH were enrolled: 71, 67, and 69 in the SG, WB and VP groups, respectively. At pre-intervention, there were significant differences in the knowledge level among the three groups: 10.51 in SG group (95% CI, 9.60-11.41), 10.93 in WB group (95% CI, 10.16-11.69), and 11.83 in VP group (95% CI, 11.19-12.46) (p<0.05). There were no significant differences in self-efficacy among the three groups. Using GEE models to analyze the effects of different HCV education interventions at different observation points, only SG group were significantly associated with an increase of HCV knowledge score at 12-week follow-up (???? = 1.16, p = 0.02). Analysis of the difference-in-differences estimates also yield similar results.
Conclusions:
All three educational interventions improved HCV knowledge and self-efficacy, with the SG approach enhancing knowledge retention, implying the benefit of digital educational intervention. Clinical Trial: Approved by the National Taiwan University Hospital Research Ethics Committee (registration number: 202206084RIN).
