Risk Factor for Depression Can Be ‘Contagious’

19.04.2013
A new study with college roommates shows that a particular style of thinking that makes people vulnerable to depression can actually “rub off” on others, increasing their symptoms of depression six months later.
The research, from psychological scientists Gerald Haeffel and Jennifer Hames of the University of Notre Dame, is published in Clinical Psychological Science, a journal of the Association for Psychological Science.

Studies show that people who respond negatively to stressful life events, interpreting the events as the result of factors they can’t change and as a reflection of their own deficiency, are more vulnerable to 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.

The 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 3 months and 6 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 3-month and 6-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 3 months of college had nearly twice the level of depressive symptoms at 6 months than those who didn’t show such an increase.

The findings provide striking evidence for the contagion effect, confirming the researchers’ initial hypothesis.

Based on these findings, Haeffel and Hames suggest that the contagion effect might be harnessed 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.”

According to the researchers, 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,” say Haeffel and Hames. “This means that cognitive vulnerability should be thought of as plastic rather than immutable.”

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
