Couples are more likely to share psychological conditions more than different cases.Credit
People with psychological disorder are likely to marry a person who has the same condition as partnership with someone who does not do so, according to a huge study1 This indicates that the pattern continues through cultures and generations.
The researchers have noticed this trend in the northern countries, but the phenomenon has rarely investigated Europe so far.
The latest study, published in The nature of human behavior Today, data from more than 14.8 million people were used in Taiwan, Denmark and Sweden. He studied the percentage of people in husbands who suffer from one of nine mental disorders: schizophrenia, bipolar disorder, depression, anxiety, hyperactivity disorder in attention deficit, autism, oxzing disorder (OCD), drug use disorder, nervous delicious.
Scientists lack a final understanding of what makes people develop psychological disorders – but genetics and environmental factors believe that both play a role.
The team found that when one of the partners was diagnosed in one of the nine cases, the other was likely to be dramatically diagnosed with the same psychological state or any other psychological state. Participant author Chun Chih, a genetic science researcher at the Institute of Brain Research in Toulsa, Oklahoma, says that the husbands were more vulnerable to the same conditions than having various cases.
“The main result is that the pattern is saved across countries, through cultures, and of course generations,” says Van. Even the changes in psychological care over the past fifty years have not turned this trend, as noted.
Obsessive -compulsive disorder, bipolar disorder and nervousness loss showed different patterns across countries. For example, in Taiwan, husbands were more likely to share obsessive -compulsive disorder than husbands in the northern European countries.
The study separated people into birth groups, from the thirties of the last century to the nineties that extend over ten years. For most disorders, the chances of diagnostic sharing partners have increased slightly with each contract, especially for those with drug abuse disorders.
What is behind this trend?
Although the study was not achieved in the causes of the phenomenon, the fan says that three theories can help explain it. First, people may be attracted to those who resemble them. “They may better understand each other because of the common suffering, so they attract each other,” he says.
Second, the common environment can make partners more similar – a process known as rapprochement. Third, the societal shame stigma represented in the presence of a psychological disorder narrows the person’s choice of the husband.
Jean -Volverton, a psychologist at the University of New South Wales in Sydney, Australia, says social and environmental pressures can contribute to a new diagnosis in a partner not previously affected, especially if they have more moderate symptoms.
