dc.description.abstract From Beckman Institute press release: “We knew from the clinical literature that there are relationships between brain volume and certain personality traits,” said Sanda Dolcos, a research scientist in psychology, and one of the study’s authors. “Lower brain volume in certain areas is associated with increased anxiety.” Coupled with questionnaires that identified the personality traits, the structural information of the prefrontal cortical regions provided evidence that there are common factors in brain structure and personality that can help provide adaptive behavior in order to avoid negative emotions. “In a statistical model, we extracted these factors, one at the brain level, one at the personality level, and we found that if you have larger volume in this set of brain regions, you had higher levels of these protective personality traits,” Moore said. The researchers are interested in identifying these brain regions along with specific personality traits in order to create ways for individuals to learn how to combat anxiety and depression.... ___________ Clarifying individual differences that predict resilience or vulnerability to emotional distress is crucial for identifying etiological factors contributing to affective disturbances, and to promoting emotional well-being. Despite recent progress identifying specific brain regions and personality traits, it remains unclear whether there are common factors underlying the structural aspects of the brain and the personality traits that, in turn, protect against symptoms of emotional distress. In the present study, an integrative structural equation model was developed to examine the associations among (1) a latent construct of Control, representing the volumes of a system of prefrontal cortical (PFC) regions including middle, inferior, and orbital frontal cortices; (2) a latent construct of Resilience personality traits including cognitive reappraisal, positive affectivity, and optimism; and (3) Anxiety and Depression symptoms, in a sample of 85 healthy young adults. Results showed that the latent construct of PFC volumes positively predicted the latent construct of Resilience, which in turn negatively predicted Anxiety. Mediation analysis confirmed that greater latent PFC volume is indirectly associated with lower Anxiety symptoms through greater latent trait Resilience. The model did not show a significant mediation for Depression. These results support the idea that there are common volumetric and personality factors that help protect against symptoms of emotional distress. These findings provide strong evidence that such brain-personality-symptom approaches can provide novel insights with valuable implications for understanding the interaction of these factors in healthy and clinically diagnosed individuals.
