The study was approved by the institutional review board of the University of Salzburg. A link to the online survey at www.unipark.com was distributed via e-mail to student mailing lists at several German and Austrian universities, via social networks, and via a posting on the website of the German version of Psychology Today. Three × 50 € were raffled among participants who completed the survey. The website was visited 1,396 times and n = 805 participants completed the entire set of questions. Fifteen participants were excluded from analyses because they answered questions too rapidly (total completion time less than 5 min), leaving a final sample size of n = 790.
