Geosocial networking phone applications (GSN apps) used to meet sexual partners have become popular in the men who have sex with men (MSM) communities of the USA since 2009. Previous studies have shown greater incidence of gonorrhea and chlamydia and lower testing frequency for HIV testing among GSN app users when compared to non-users. The present study aims to determine the type, number, and frequency of apps used, as well as the association between dispositional self-control and health-related behaviors. Participants (n = 146) were recruited from Amazon's Mechanical Turk program to respond to a brief GSN app marketing survey. Multivariate regression was used to determine differences in app priorities, length of app use, and number of sexual partners between high self-control and low self-control participants. A majority of the participants reported using Grindr (78 %) followed by Scruff (19 %), Growlr (12 %), and Jack'd (12 %). Most individuals used one app only (58 %), but a significant proportion reported using two apps (28 %) or three or more apps (14 %). Respondents with low self-control were more likely to report a higher number of hours using GSN apps and a higher number of sexual partners, controlling for race/ethnicity, education, employment, and HIV status. Given the popularity of this burgeoning communication medium, these findings have important implications for developing prevention resources for different segments of GSN app users.
