How Relationship Satisfaction and Negative Communication Trajectories Change in Emerging Adults' Dating Relationships: A Group-Based Dual Trajectory Analysis.

Early romantic relationships are salient to the development of healthy future relationships. Yet, little is known about the evolution of romantic relationships of emerging adults since most of the research has been conducted on married or well-established couples. The current study aims to examine how relationship satisfaction and negative communication evolve and are interrelated during emerging adulthood. Using age as a time metric, we conducted group-based dual trajectory modeling analyses on 1566 unmarried Canadian individuals (from 17 to 24 years old) in a relationship, who could either stay with the same partner or change partner over time. A four-group model for relationship satisfaction and a four-group model for negative communication were found. Dual analyses highlighted the high concordance between specific trajectories of both constructs. These findings demonstrate that relationship satisfaction and negative communication do not evolve in the same ways for everyone and provide useful insights to existing clinical interventions.

Spousal Support and Relationship Happiness in Adults With Type 2 Diabetes and Their Spouses.

OBJECTIVES: The purpose of this study was to examine the association between the perceptions of spousal support self-efficacy in terms of dietary self-care and relationship happiness. METHODS: Forty-six couples, in which only one spouse has type 2 diabetes, completed questionnaires on perceptions of spousal support self-efficacy and relationship happiness. RESULTS: Using an actor‒partner interdependence model, we found that, when persons with type 2 diabetes were more confident in their spouse's ability to provide them with support regarding their dietary self-care, they reported more relationship happiness. We also found that, when their spouse without diabetes was more confident in their own abilities to provide such support to their partner, they reported more relationship happiness. However, the person with diabetes' confidence in their spouse's support abilities and the spouse's confidence in their own support abilities were not associated with the other partner's relationship happiness. CONCLUSIONS: This study offers a unique dyadic perspective on the determinants of happiness for couples in which one spouse has type 2 diabetes. The perceived quality of spousal support appears to be associated with relationship happiness in committed couples managing diabetes, regardless of the actual support received or provided.
