A study of an isolated Bolivian society found that five widely accepted personality traits may not be universal, instead revealing a unique 'Big Two' structure including prosociality and industriousness. Researchers suggest expanding beyond Western populations to better understand personality development.
Patients with depressive disorders and borderline personality disorder have significantly higher unemployment rates than those without the condition. Persistent unemployment poses a significant public health burden, with 13.4% of patients missing up to two years or more from work.
A study by UK researchers found that attending physicians tend to rate borderline performances lower when previously exposed to good, rather than poor, performances. This contrast bias may result in biased judgments in competency-based education assessment systems.
Researchers found that the order of symptoms matters more for clinicians' descriptions of disorders that are different than those that overlap. This contradicts the assumption that order doesn't matter in psychiatric diagnoses. The study's findings have implications for bringing classification and clinical practice closer together.
