Are there genetic vulnerabilities for depression across cultures?
Genetic vulnerability differs substantially from country to country. East Asian contexts, for example, show a high prevalence of genes associated with depression. Yet, despite these vulnerabilities, they develop fewer cases of the disorder. One hypothesis is that genetic vulnerabilities have co-evolved with culture, creating extra protective factors (in this case, extra interdependence). However, when these people leave their cultural contexts, they have a higher risk of developing depression.
That is an interview with Yulia Chentsova-Dutton, associate professor of psychology at Georgetown, and a researcher in this area. You can imagine further applications of this mechanism. The interview has other interesting points, for instance:
What is the role of emotion regulation?
Emotion regulation is increasingly becoming understood as a core factor in all affective disorders. In western societies, we don’t see enough adaptive strategies like reappraisal: learning to tell yourself a different story that would eventually lead to different emotions. There is also not enough social regulation of emotion, which occurs by sharing our emotions with others. Research shows that cultures can facilitate functional regulation strategies. For example, Igor Grossmann’s work shows that Russians make rumination (generally considered a dysfunctional strategy) more functional by encouraging people to ruminate about the self from another person’s perspective, making rumination almost reappraisal-like in its quality.
