Ottawa Couples Diary Study, 2016

We recruited 122 mixed-sex couples from Canada via online ads posted in five major Canadian cities (Reddit, Kijiji) and through advertisements posted in public locations in a major Canadian city. Couples were eligible to participate if they were in an exclusive, monogamous relationship for at least 2 years and were living together (couples were pre-screened for eligibility via email and telephone).

Couple members each completed a background survey (approximately 55 minutes in length). Then, each couple member started the 21-day diary study on the same day. Each couple member completed 21 daily diaries in total. On average, participants completed 19.56 out of 21 days. We followed-up with each couple member 3-months later.

At the daily level, we assessed relationship and sexual experiences (e.g., satisfaction, commitment, boredom, conflict, types of love, sexual desire and satisfaction).

At the 3-month follow-up, we assessed relationship quality (e.g., satisfaction, thoughts of separation, boredom, self-expansion).
