This paper provides a speculative discussion on what quasi-experimental designs might be useful in various aspects of HIV/AIDS research. The first author’s expertise is in research design, not HIV, while the second author has been active in HIV prevention research. It is hoped that it may help the HIV/AIDS research community in discovering and inventing an expanded range of possibilities for valid causal inference. DOI:10.2458/azu_jmmss_v3i1_campbell

With the growth of product search engines such as pricegrabber.com, web vendors have many more casual visitors. This research examines how web vendors may foster “swift trust” as a means to convert casual visitors to paying customers. We examine whether perceptions of website’s appearance features (normality, social presence and third-party links) and functionality features (security, privacy, effort expectancy and performance expectancy) positively relate to swift trust in a web vendor. Using a quasi-experimental research design, we empirically test the proposed relationships. Based on an analysis of 224 respondents, we found appearance and functionality features explained 61% of the variance in swift trust. The paper concludes with a discussion of findings and implications.
