Yet disclosure poses significant challenges in the face of persistent societal stigma. Few interventions focus on decision-making self-efficacy, and communication skills to support disclosing HIV status to an intimate partner. Virtual reality (VR) and artifcial intelligence (AI) technologies offer poweful tools to address this gap. Informed by Social Cognitive Theory, we created the Tough Talks VR program for HIV-positive young men who have sex with men (YMSM) to practice status disclosure safely and confidentially. Fifty-eight YMSM (ages 18 - 30, 88% HIV-positive) contributed 132 disclosure dialogues to develop the prototype through focus groups, usability testing, and a technical pilot. The prototype includes three disclosure scenarios (neutral, sympathetic, and negative response) and a database of 125 virtual character utterances. Participants select a VR scenario and realistic virtual character with whom to practice. In a pilot test of the fully automated neutral response scenario, the AI system responded appropriately to 71% of participant utterances. Most pilot study participants agreed Tough Talks was easy to use (9/11) and that they would like to use the system frequently (9/11). Tough Talks demonstrates that VR can be used to practice HIV status disclosure and lessons learned from program development offer insights for the use of AI systems for other areas of health and education.","PeriodicalId":90485,"journal":{"name":"Digital culture & education","volume":"10 ","pages":"22-48"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6097708/pdf/nihms-981443.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36410540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Platforms were compared by study completions (yield), time to completion, completion to enrollment ratios (CERs), and costs/ completion; and by participants' demographic characteristics, HIV testing history, and health literacy levels. Of the 482 English-speaking participants, Amazon Mechanical Turk yielded the most participants, recruited participants at the fastest rate and had the highest CER (0.78) and lowest costs / completion. Of the 335 Spanish-speaking participants, Facebook yielded the most participants and recruited participants at the fastest rate, although Amazon Mechanical Turk had the highest CER (0.72) and lowest costs/completion. Across platforms participants differed substantially according to their demographic characteristics, HIV testing history and health literay skills. The study results highlight the need for researchers to strongly consider choice of Internet or social media plaforms when conducting Internet-based research. Because of the sample specifications and cost restraints of studies, specific Internet/ social media or participant selection plaforms will be much more effective or appropriate than others.","PeriodicalId":90485,"journal":{"name":"Digital culture & education","volume":"7 1","pages":"40-86"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4912013/pdf/nihms785382.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34665116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At first there was enthusiasm—it was a new tool that could be ‘repurposed’ for education; then, as Facebook became more widespread, its use seemed less than opportune. But now, with so many students already engaged before they even come to a university, perhaps it is impossible to avoid the conclusion that Facebook is as natural to education as the commute, the computer, and everything else which students ‘bring’. This paper first presents a summary of what Facebook affords, by way of its design and use, for online communication and networking, demonstrating the central role of reciprocal acts of attention exchange in this system. It then analyses, through a critical reading of research into Facebook and education, the way Facebook challenges traditional understandings of university education and the relationships between teachers and students. It concludes that, however we might seek to use Facebook in higher education (and there are many reasons we might), its use will always be shaped by—and indeed give rise to—a blurring of the traditional boundaries between formal and informal education.","PeriodicalId":90485,"journal":{"name":"Digital culture & education","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70459447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HealthMpowerment.org (HMP) is a mobile phone optimised online intervention that utilises behaviour change and gaming theories to reduce risky sexual behaviours and build community among HIV-positive and negative YBMSM/TW. The intervention is user-driven, provides social support, and utilises a point reward system. A four-week pilot trial was conducted with a diverse group of 15 YBMSM/TW. During exit interviews, participants described how HMP components led to behaviour changes such as asking partners' sexual history, increased condom use, and HIV/STI testing. The user-driven structure, interactivity, and rewards appeared to facilitate sustained user engagement and the mobile platform provided relevant information in real-time. Participants described the reward elements of exceeding their previous scores and earning points toward prizes as highly motivating. HMP showed promise for being able to deliver a sufficient intervention dose and we found a trend toward higher dose received and more advanced stages of behaviour change. In this pilot trial, HMP was well accepted and demonstrates promise for translating virtual intervention engagement into actual behaviour change to reduce HIV risk behaviours.","PeriodicalId":90485,"journal":{"name":"Digital culture & education","volume":"6 3","pages":"164-182"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4292870/pdf/nihms643354.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32979919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
