Add to Roommate Issues: Their Depression May Be Catching
Provocative new research now suggests that a particular style of thinking that makes people vulnerable to depression can influence others, increasing their symptoms of depression as much as six months later.
Psychological scientists Gerald Haeffel, Ph.D., and Jennifer Hames of the University of Notre Dame studied college roommates to determine if the way in which an individual thinks of things can actually “rub off” on others causing detrimental effects.
It has long been known that some people are more vulnerable to depression than others. Those that respond negatively to stressful life events — interpreting the events as the result of factors they can’t change and, importantly, as a reflection of their own deficiency — are particularly at risk for depression.
This “cognitive vulnerability” is such a potent risk factor for depression that it can be used to predict which individuals are likely to experience a depressive episode in the future, even if they’ve never had a depressive episode before.
Individual differences in this cognitive vulnerability seem to solidify in early adolescence and remain stable throughout adulthood, but Haeffel and Hames predicted that it might still be malleable under certain circumstances.
In the study, published in Clinical Psychological Science, researchers hypothesized that cognitive vulnerability might be “contagious” during major life transitions, when our social environments are in flux.
They tested their hypothesis using data from 103 randomly assigned roommate pairs, all of whom had just started college as freshmen.
Within one month of arriving on campus, the roommates completed an online questionnaire that included measures of cognitive vulnerability and depressive symptoms.
They completed the same measures again three and six months later; they also completed a measure of stressful life events at the two time points.
The results revealed that freshmen who were randomly assigned to a roommate with high levels of cognitive vulnerability were likely to “catch” their roommate’s cognitive style and develop higher levels of cognitive vulnerability; those assigned to roommates who had low initial levels of cognitive vulnerability experienced decreases in their own levels.
The contagion effect was evident at both the three-month and six-month assessments.
Most importantly, changes in cognitive vulnerability affected risk for future depressive symptoms: Students who showed an increase in cognitive vulnerability in the first three months of college had nearly twice the level of depressive symptoms at six months than those who didn’t show such an increase.
The findings provide striking evidence for the contagion effect. As a result of these findings, researchers posited that the contagion effect might be flipped to help treat symptoms of depression.
“Our findings suggest that it may be possible to use an individual’s social environment as part of the intervention process, either as a supplement to existing cognitive interventions or possibly as a stand-alone intervention,” they write.
“Surrounding a person with others who exhibit an adaptive cognitive style should help to facilitate cognitive change in therapy.”
Thus, surrounding an individual during a vulnerable time of life with positive energy givers (those with an adaptive cognitive style), may mitigate the development of depression.
Similarly, the results of this study indicate that it may be time to reconsider how we think about cognitive vulnerability.
“Our study demonstrates that cognitive vulnerability has the potential to wax and wane over time depending on the social context,” said Haeffel and Hames. “This means that cognitive vulnerability should be thought of as plastic [changeable] rather than immutable.”
