A longitudinal investigation of marital dissolution, marital quality, and generalized anxiety disorder in a national probability sample

Generalized anxiety disorder (GAD) is a common psychiatric disorder that is associated with high levels of distress and impairment. The present study was conducted to examine the 10-year longitudinal associations between marital dissolution, three measures of marital quality, and GAD among married participants from the Midlife in the United States (MIDUS) survey, a probability sample of American adults aged 24-74 years. Results indicated that GAD at baseline was significantly and positively associated with incidence of marital dissolution during the 10-year follow-up and marital strain (i.e., negative partner interaction) at baseline was significantly and positively associated with incidence of GAD at the 10-year follow-up. These associations remained statistically significant after adjusting for demographic characteristics and neuroticism. In comparison, marital satisfaction and marital support (i.e., positive partner interaction) at baseline were not significantly associated with incidence of GAD, GAD at baseline was not significantly associated with any of the three measures of marital quality at follow-up, and marital dissolution during follow-up was not significantly associated with incidence of GAD. These findings suggest that negative interactions with one's partner may be a risk factor for GAD and that improving marital functioning may be important for the prevention and treatment of GAD.
