Swipe Right: Dating Website and App Use Among Men Who Have Sex With Men.

This study explored the frequency of dating website and app usage among MSM to understand sub-group differences in use. Web-based survey data (<italic>N</italic> = 3105) were analyzed to assess the use of dating websites and apps. More than half (55.7%) of MSM in this sample were frequent users of dating websites and apps. Two-thirds (66.7%) of frequent users had casual partners only in the past 12 months and reported a high average number of casual sexual partners in the past 12 months (<italic>Mdn</italic> = 5.0) compared to never users (<italic>Mdn</italic> = 0.0; <italic>χ</italic>²(2) = 734.94, <italic>adj. p</italic> < .001). The most frequently used dating website or app was Grindr, with 60.2% of the sample reporting some or frequent use. Adam4Adam (23.5%), Jack’d (18.9%) and Scruff (18.7%) were also frequently used. Dating websites and apps may be effective channels to reach a diverse group of MSM with HIV prevention messages. [ABSTRACT FROM AUTHOR]
