Study Links Unpredictable Childhoods to Borderline Personality Traits in Adults
A study published in Evolutionary Psychological Science has found a correlation between unpredictable childhood environments and the development of borderline personality traits in adulthood. Researchers, including Virgil Zeigler-Hill, examined how childhood instability affects traits such as emotional volatility, impulsivity, and interpersonal conflict. The study involved 4,993 participants across three separate studies, including U.S. adults and students, as well as Israeli adults. Participants reported their childhood experiences using the Perceived Childhood Harshness and Unpredictability Scale. The findings suggest that those who experienced more unpredictable childhoods reported higher levels of borderline traits, regardless of the severity of childhood hardship.
