Infant mortality and poor birth outcomes are major public health issues in the United States that disproportionately affect African American families. In response, the researcher created the innovation of e-health featuring nine avatar videos covering the nine contemporary methods of pregnancy prevention, as well as other content hosted on www.DIVAhealth.org/PregnancyPortal . Some 78 African American women met study eligibility criteria, resulting in a sample with a mean age of 32 years (M=32.33, SD = 7.78, Min 20, Max 47), while composed of women mostly born in the United States (66.7%, n= 52). The mean income for the sample was $40,000 (SD= 19,000, Min $0, Max $499,000), while nearly all (97.4%, n=76) were employed. More than one-third (34.6 %, n=27) were married, while most were single (44.9%, n=35). After watching the nine avatar videos as a potential brief e-health intervention, the women rated their knowledge as "very good" post intervention (Mean=5.40; SD=.67) compared to "good" prior intervention (Mean=4.24; SD=1.04); t= - 9.709, df = 76, p =.000). Furthermore, after watching the videos, their stage of change for pregnancy prevention with their main partner went to the higher level—or from between preparation and action but closest to action up to the stage of action. The overall rating for the videos was "Very Good"– Mean = 4.96; SD=1.11 and Mean =5.03; SD=1.01, respectively, for each of the two questions. The best predictors of a high rating of the videos were: 1) living with a partner (B = .803, SE = .216, p = .000); 2) not having a main sexual partner (B = - 1.018, SE = .391, p = .012); 3) not using a method of pregnancy prevention that required negotiation with a partner (B = ha-.567, SE = .256, p = .031); 4) having a lower annual household income (B = - .146, SD = .066, p = .018); and 5) having a higher correct knowledge of pregnancy prevention methods (B == .333, SE = .066, p = .000); R Square = .446, Adjusted R Square = .397, or 39.7% of the variance was explained by the model.
