Emerging adulthood is an intense period of personal development and interpersonal exploration; most emerging adults engage in several romantic relationships of varying commitment levels throughout their late teens and early twenties. The current study explored whether one relationship behavior, staying over, is related to specific demographic characteristics, previous experiences, and personal beliefs and attitudes. A sample of 627 emerging adults were surveyed about their experiences with staying overnight with their romantic partners, their reasons for doing so, and their attitudes about fullātime cohabitation. Participants who were older, had cohabited at some point, lived independently from family, viewed religion as unimportant, and had positive attitudes about cohabitation were found to be more likely to stay over.
