The responses provided the foundation for a new model of how couples keep their relationship exciting. The model includes exciting activities that are passionate, adventurous, playful, sexual, spontaneous, and romantic, along with three relationship-maintaining activities: communicating effectively, joint activities, and autonomy. In Study 2, 104 adults rated their relationship on the three relationship-maintenance variables, on exciting activities, on excitement, and on relationship satisfaction. The relationship-maintenance and exciting activities showed significant associations with both excitement and satisfaction, providing preliminary support for the model.
