Are lonely people more likely to have problems with mental health? Yes, but the obverse is also true.
“We have found a correlation between loneliness and several mental health problems,” says Associate Professor Rubén Rodríguez-Cano at the Norwegian University of Science and Technology (NTNU’s) Department of Psychology.
In a new study, researchers are looking at whether lonely people are more prone to problems such as depression and psychosis. Based on medication use, the correlation is clear.
The results have been published in BJPsych Open.
The mental health problems identified by the study are both serious and wide-ranging.
“Our research indicates that loneliness increases the risk of developing psychosis, bipolar disorders and severe depression,” says Rodríguez-Cano.
But is it loneliness that causes the mental health problems, or is it the mental health problems that cause people to feel lonely?
It can be both.
“When evaluating how loneliness develops from adolescence to adulthood, we found that people with psychotic and bipolar disorders are more likely to experience increased loneliness after adolescence.
Although we cannot identify causality in our study, the correlation between loneliness and serious mental illness is clear from a long-term perspective,” says Associate Professor Rodríguez-Cano.
