Adolescent girls are at substantial risk of sexually transmitted diseases including HIV. To reduce these risks, we developed Health Education And Relationship Training (HEART), a web-based intervention focused on developing sexual assertiveness skills and enhancing sexual decision-making. This study assessed the feasibility and acceptability of this new program and examined if perceived acceptability varied according to participant ethnicity, sexual orientation or sexual activity status. Participants were part of a randomized controlled trial of 222 10th-grade girls (Mage = 15.26). The current analyses included those in the intervention condition (n = 107; 36% white, 27% black and 29% Hispanic). HEART took approximately 45 min to complete and was feasible to administer in a school-based setting. Participants found the program highly acceptable: 95% liked the program and learned from the program, 88% would recommend the program to a friend and 94% plan to use what they learned in the future. The primary acceptability results did not vary by the ethnicity, sexual orientation or sexual activity status of participants, suggesting broad appeal. Results indicate that this new online program is a promising method to reach and engage adolescents in sexual health education.
Pathogen contamination of water has a massive impact on global human health. In particular, viruses pose unique challenges to water treatment techniques due to their small size and presence in water as both individual virions and when absorbed onto larger particles. Low-energy water treatment processes such as media filtration are not capable of completely removing viruses owing to their small size. Hence, less sustainable processes with high chemical or energy consumption such as chemical disinfection, ultraviolet irradiation, and membrane filtration are usually required. To overcome high energy and/or chemical requirements for virus treatment, designs for sustainable fiber filters fabricated from minimally processed natural materials for efficient virus (MS2) and bacteria (E. coli) removal are presented in this work. These filters were created by functionalizing readily accessible natural fibers including cotton, silk, and flax with a simple aqueous extract containing cationic proteins from Moringa oleifera seeds. The proposed filters offer a comprehensive low cost, low energy, and low environmental impact solution for pathogen removal from water with removals of >7log10 (99.99999%) for viruses and bacteria.
This article describes the development of ProjectHeartforGirls.com, an interactive web-based program designed to improve sexual communication skills and reduce the risk of HIV/STDs among adolescent girls, a population at heightened risk for negative sexual health outcomes (CDC, 2013). Although sexual communication is a critical predictor of safer sex among teens, there are few online interventions that target these skills as a central program component. We developed ProjectHeartforGirls.com to fill this gap. Program development involved 1) identifying the target population (ethnically-diverse high school girls); 2) clarifying the theoretical foundation (Reasoned Action Model); 3) conducting formative qualitative research (n=25 girls); 4) drafting initial program content; 5) receiving ongoing feedback from a teen advisory board (n=5 girls); 6) programming online content; and 7) conducting usability testing (n=6 girls). These steps are described along with the final intervention product, which is currently being evaluated in a randomized controlled trial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
