Hope is a mental resource and a robust predictor of well-being, which allows individuals to better cope with hardship. Little is known about dyadic hope - i.e., hope serving as a joint resource within intimate relationships. We examined dyadic hope in a sample of 100 couples in early parenthood, a challenging though common phase in couples' lives. Three months after becoming parents, both partners completed daily diaries for 3 weeks, reporting their daily hope, stressors, and three types of outcomes: individual, relational, and parental. Using multilevel actor-partner interdependence models, we found that greater hope (both daily and person-level) was positively associated with better actor and partner outcomes of all three kinds. Additionally, hope buffered various daily stressors. Our results show that hope is a personal and shared resource for couples in this pivotal juncture, and thus may constitute a target for future interventions.
