"Stressful life events like divorce are associated with significant risk for prolonged emotional distress, including clinically-significant depression," notes psychological scientist and lead researcher David Sbarra of the University of Arizona.
"At the same time, we know from considerable research that the experience of divorce is non-random. Some people are much greater risk for experiencing a divorce than other people."
This led Sbarra and colleagues to wonder: Is it divorce, or the factors leading to divorce – such as marital discord, neuroticism, or hostility – that increase the risk for depression?
To investigate this question, the researchers took advantage of data from the longitudinal, nationally representative Midlife Development in the United States (MIDUS) study. The researchers matched each participant who had separated or divorced during the study to a continuously married person in the study who had the same propensity to divorce, based on a number of previously identified factors. By comparing participants to their match, the researchers were able to account for the fact that it's impossible to randomly assign people to divorce or stay married.
In line with previous research, the results showed that divorce had a significant effect on subsequent depression.
But, as Sbarra and colleagues found, the full story was a bit more complex.
Specifically, divorce or separation only increased the likelihood of a later depressive episode for those participants who reported a history of depression. In fact, nearly 60% of adults with a history of depression who divorced during the study experienced a depressive episode at the follow-up assessment.
For all other participants – including those who had a history of depression but hadn't divorced, and those who divorced but had no history of depression – there was no elevated risk for a future depressive episode. Only about 10% of these people experienced a depressive episode at follow-up.
The magnitude of the difference between the two groups – 60% versus 10% – surprised the researchers.
"These findings are very important because they affirm the basic notion that most people are resilient in the face of divorce and that we do not see severe disorder among people without a history of a past depressive illness," says Sbarra. "If you've never experienced a significant depression in your life and you experience a separation or divorce, your odds for becoming depressed in the future are not that large at all."
The findings suggest that separation and divorce may exacerbate underlying risk but don't, in and of themselves, increase rates of depression. It's possible, the researchers speculate, that people with a history of depression have a limited capacity to cope with the demands of the transition out of marriage, but they caution that the specific mechanisms have yet to be explored.
"Do these people blame themselves for the divorce? Do they ruminate more about the separation? Are they involved in a particularly acrimonious separation? These questions deserve much greater attention," says Sbarra.
Sbarra and colleagues also note that the research can't speak to potentially interesting differences between those adults who separate versus those who divorce, since the two categories were combined in the study.
Nonetheless, the researchers believe the new findings have significant clinical implications:
"It is very important for clinicians to know that a person's history of depression is directly related to whether or not they will experience a depressive episode following the end of marriage," says Sbarra. "People with a history of depression who become divorced deserve special attention for support and counseling services."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
