The purpose of this study is to test the efficacy of alternative methods to improve survey completion.

Men who have sex with men (MSM) are the risk population most heavily impacted by HIV in the United States by any measure; in 2009, at least 61% of new HIV infections were estimated to have occurred in MSM. MSM are experiencing an increase in HIV transmission that has been occurring since at least 1990, and accelerated in multiple North American and European countries from 2000-2005. The expansion of the HIV epidemic has been proposed to be attributable, in part, to the extent to which the internet has facilitated sexual connectivity among MSM.

Researchers have attempted to reach MSM for HIV prevention research and intervention on the internet. In the past 10 years, there has been a proliferation of internet surveys and HIV research studies among men who have sex with men that utilize the internet for data collection and, in some cases, the delivery of HIV prevention content. The development of internet-based interventions has been recently identified as especially promising because of its potential for scalability. However, there are also important limitations to internet-based data collections and prevention studies. The most important of these relate to representativeness and opportunities to introduce bias to data collections and differences in access to and use of internet among different subgroups of MSM. Equally important, although less discussed, are the unique ethical and human research protections challenges posed by online sexual health prevention studies.

The investigators will conduct an experiment to improve knowledge of how to conduct internet-based HIV prevention research with MSM in ways that decrease biases in data collections. The design will consist of a randomized controlled trials of MSM recruited online. A total of 1000 MSM will be enrolled to determine how to best improve retention in online surveys.
