The goal of the present research was to examine how approach relationship goals shape shared activity planning and engagement. In a two-part study, 135 primarily dating participants planned a date to engage in with their partner, and were instructed to engage in the date during the next six days. One week later, participants completed a follow-up questionnaire about their enacted date. People higher in approach goals engaged in shared activities that were significantly more self-expanding, and desired to participate in these activities more frequently in their relationship. Thus, people higher in approach goals are more dedicated and committed to the dates that they engage in, believe their partner will be interested in these dates, and have a greater desire to participate in future self-expanding dates. These findings suggest that people higher in approach goals are more adept at planning growth-enhancing time with their partners.
