(2016). _Date me for science speed-dating study_. doi: 10.17605/osf.io/nwvr3 <br> <br> **Overview of Study Features:** In the “Date me for Science” study, a total of 400 heterosexual participants who were currently looking for a romantic partner were invited to one of 42 speed-dating events in our laboratory. At each speed-dating event, 5 female and 5 male participants had 3-minute videotaped speed-dates with each participant of the opposite sex, resulting in 25 speed-dates per event. After each speed-date, participants filled in a post-date questionnaire about their respective dating partner, including their wish to exchange contact information with the dating partner (“Yes” vs. “No”). Matching pairs (i.e., dating-dyads that “yessed” mutually) were followed up in 3 online questionnaires at 10 days, 20 days, and 40 days after they received the contact information from us. Finally, all participants were contacted again exactly one year after their speed-dating event for a short online questionnaire. <br> <br> **Assessed Measures…**<br> **…before the speed-dating event:** <br> - online pre-event questionnaire (administered at least one day before the speed-dating event): - participants’ self-reports on a wide range of personality traits <br> (e.g., Big Five, sociosexuality, mate value, attachment style, self-esteem, short-term vs. long-term relationship orientation) - demographics and the like (e.g., education, income, body height and weight, health, dating history) - participants’ stated partner preferences on a diverse set of 43 characteristics and participants’ self-evaluation on the same characteristics <br> **…at the speed-dating event:**<br> - post-date questionnaires (after each single speed-date at the speed-dating event): - several measures of romantic attraction towards the respective dating partner <br>(e.g., “I think, this person is romantically appealing”; “To me, this person might be a partner for a one-night stand or a sexual affair”; “To me, this person might be a partner for a long-term committed romantic relationship”), as well as meta-perception on the same measures (e.g., “My speed-dating partner thinks I am romantically appealing”) - ratings about the dating partner on a diverse set of characteristics <br>(e.g., mate value, as well as all 43 characteristics from the partner preferences assessment in the pre-event questionnaire) - wish to exchange contact information with the dating partner (“Yes” vs. “No”) - videotapes of all speed-dates<br> - portrait photograph and full-body photograph of each participant<br> - state measures (affect, mate value) at the beginning and the end of the event <br> **…after the speed-dating event:**<br> - online match follow-up questionnaires (at 10, 20, and 40 days after receiving the contact information): the frequency of and quality of interactions between matching-pair participants (including several measures of romantic attraction) after the speed-dating event<br> - online 1-year follow-up questionnaire (exactly one year after the speed-dating event): <br> - dating history in the past year (including current relationship status)<br> - the frequency of and quality of interactions between speed-dating participants (including several measures of romantic attraction) after the speed-dating event
