IntroductionAlthough some studies have found a link between dating apps and sociodemographic variables, sexual attitudes, and sexual risk behaviors, few studies in Spain have explored these relationships. This study analyzes the relationship between the use of dating apps and these variables in this country.MethodA total of 2288 people aged between 18 and 35 years completed a questionnaire, which, in addition to sociodemographic variables, contained questions on the use of dating apps, a measure of attitudes toward online sexual behaviors, and indicators of sexual risk behaviors.ResultsThe percentage of men using dating apps is higher than that of women, and the percentage of LGB users is higher than that of heterosexuals. In addition, users have more positive attitudes toward online sexual behavior than non-users. In general, users are also found to have more sexual partners than non-users, although they more frequently use condoms for vaginal intercourse and anal sex.ConclusionThe present study provides evidence for the relationship between the use of dating apps and certain variables in Spain.Policy ImplicationsDating apps do not have to be equated with sexual risk, but condom use should continue to be encouraged, especially among those who have multiple sexual partners.
