Participants were a diverse set of 222 undergraduate students involved in an ongoing romantic relationship. At the start of the study, participants averaged 23 years of age, and had been with their current partner for an average of 2.5 years. As you can see in the figure on the right, the majority of the participants were women.
Most of the participants (68.4%) were involved in dating relationships, 25% were cohabitating, and 6.6% were married.
