The study involved the design and evaluation of e-health using avatar videos designed to serve as a brief online intervention—using a diverse sample (n=115) of men: mean age of 36.99 years (min 18, max 78, SD = 13.008); 60.9% (n=70) U.S. born; and 84% (n=100) having a Bachelor's to Doctoral Degree. The study introduced the Knowledge of HIV Window Period scale and an avatar video educating on the HIV Window Period. For knowledge of the HIV window period, the sample had a mean of 34.496 (min 5, max 51, SD =12.495), suggesting moderate knowledge, while. Most (77.9% , = 93) rated the video as excellent to good.
Paired t-tests showed that post-video viewing mean scores were significantly higher than pre-video viewing means on several scales, suggesting both movement across the stages of change and an increase in self-efficacy from pre- to post-video viewing. This suggested positive brief intervention effects from exposure to e-health.
For the study outcome variable of higher knowledge of the HIV window period, Pearson correlations showed: the higher the knowledge of the HIV window period, then the higher the education level of the men (r=.337, p < .000). When comparing those who had ever tested for HIV compared to those who had never tested for HIV, the group that had tested for HIV had a significantly higher group mean score for knowledge of the HIV window period (t = -2.715, df = 112.997, p = .008). Further, backward stepwise regression showed that the study outcome variable of higher knowledge of the HIV window period was significantly predicted by higher level of education (B=3.085, SEB =.917, p = .001) and higher level of self-efficacy for testing for HIV (B=1.635, SEB =.704, p = .022) [R 2 =.135, Adj R2=.118]—meaning 11.8% of the variance was explained by this model.
Regarding whether the men could be considered adopters of the new innovation of diffusing e-health on the HIV window period, and would diffuse the innovation by sharing the avatar video with others, the vast majority (89.6%, n = 103) indicated that that would recommend the avatar video.
