66 percent of patients with TBI remained married to the same person, without separation or divorce. Of marriages that ended, 68 percent did so within five years after TBI, including 39 percent within the first year.

“Marital stability over the 10-year period was higher for those who were older, were female, and had no problematic substance use history,” the researchers write. The risk of a breakup didn’t seem to be related to race/ethnicity, education, cause of injury, or injury severity.

Some reports suggested high divorce rates after TBI. However, in previous studies, reported rates of marital instability after TBI varied widely: from 22 to 85 percent. Long-term follow-up in a large sample of patients with TBI are major strengths of the new study.

The results question previous studies suggesting a high divorce rate among patients who are married at the time they sustain a TBI. The study also provides insights into risk factors for a marital breakup after TBI. The findings are consistent with the known bidirectional link between TBI and substance use.

“While substance use itself may not cause marital instability, a spouse’s perception that substance use is problematic may contribute to marital instability,” Dr. Hammond and coauthors write.

The high risk of marital loss within the first few years after TBI suggests that early education and support might be helpful. The researchers note some important limitations of their study – including the lack of information on the quality of the marital relationship before TBI.

The findings may help to identify couples who may be at high risk of marital instability after TBI, and to guide patient and family education, relationship counseling, and other marital interventions, Dr. Hammond and colleagues believe.

They conclude, “Interventions aimed at substance use prevention and functional improvement may also have relevance to facilitating marital stability.”
