Sexual and Relationship Satisfaction associated with Shifts in Dyadic Trajectories of Depressive Symptoms in German Couples across Four Years.

Depression is a pervasive mental health concern; thus, it is important to identify modifiable factors associated with reducing depressive symptoms across time. Using 1,876 heterosexual couples assessed annually across 4 years from the Panel Analysis of Intimate Relationships and Family Dynamics (Pairfam) study, time-varying covariate growth models tested if sexual and relationship satisfaction were linked with shifts in trajectories of depressive symptoms across time. For both men and women, higher sexual and relationship satisfaction scores were significantly associated with decreasing their own depressive symptom trajectories, but only relationship satisfaction was linked with their partners' depressive symptom trajectories. Potential clinical implications include the treatment of depressive symptoms by making changes across time in their own relationship satisfaction and sexual satisfaction.
