Sex Touch Dyadic Daily Diary Study, 2016

We recruited 98 couples from Canada via online ads (posted on Kijiji). Couples were eligible to participate if they were together in a relationship for at least 2 years, were living together and each partner was at least 18 years old (couples were pre-screened for eligibility via email and telephone). Participants’ age ranged from 21 to 61 (M=33 years, SD=8 years) and had been in the relationship between 2 to 25 years (M=8 years, SD=5 years). Couple members each completed a background survey. Then, each couple member started the 28-day diary study on the same day. Each couple member had to complete 28 daily diaries each evening in total. On average, participants completed 24.7 out of 28 days. We followed-up with each couple member 3-months later. Measures: At background, we assessed demographics, individual differences (e.g., attachment styles, Big Five, satisfaction with life) and relationship and sexual experiences (e.g., relationship and sexual satisfaction, (sexual) communal strength, communication patterns). At the daily level, we assessed individual experiences (e.g. mood) as well as relationship and sexual experiences (e.g., satisfaction, commitment, sexual desire and satisfaction). At the 3-month follow-up, we assessed individual well-being and relationship quality (e.g., relationship and sexual satisfaction). The study was approved by Office of Research Ethics of the University of Toronto (# 32147).
