Daily Relationships Experiences Study, 2018

We recruited 122 couples through online (e.g., Reddit, Kijiji, Facebook, Craigslist) and physical (e.g., university campuses, public transportation centers) advertisements in Canada and the United States.

Eligible couples were currently living together or seeing each other at least five out of seven days, sexually active, 18 years of age or older, residing in Canada or the United States, able to read and understand English, and had daily access to a computer with internet. Both partners had to agree to participate.

One couple was excluded because they only completed the baseline survey of the study. The final sample consists of 121 couples ranging in age from 20 to 78 years (M = 32.63, SD = 10.19). The sample was primarily White/Caucasian (65.3%), straight/heterosexual (81.4%), and married (46.7%), and the average relationship length was 8.50 years (SD = 8.41).

Couples were pre-screened for eligibility via e-mail and telephone. Once eligibility and consent were confirmed, each partner completed a 60-minute online background survey, followed by 10- to 15-minute online surveys for 21 consecutive days, and a 20-minute online follow-up survey three months later. Participants were asked to complete the surveys before bed each night and to begin the study on the same day as their partner. Each partner was compensated up to $60 CAD ($48 USD).
