Personality impairments link childhood maltreatment to adult anxiety

A recent study published in Psychological Reports has found a strong link between childhood maltreatment and the development of anxiety in adulthood. The research, led by clinical psychologist Stephanie Vaccarezza from the Pontificia Universidad Católica de Chile, reveals how emotional abuse and neglect disrupt fundamental personality traits, contributing to anxiety symptoms.

Generalized anxiety disorder, characterized by excessive and disproportionate worry, is one of the most common mental health conditions worldwide. Childhood maltreatment, which includes physical, emotional, and sexual abuse, as well as emotional and physical neglect, has long been recognized as a risk factor for severe and treatment-resistant anxiety.

This study aimed to explore the psychological mechanisms connecting early adversity to later anxiety, focusing on "personality functioning." This term describes how well a person navigates their own identity and relationships with others. The researchers identified two key aspects of personality functioning: self-functioning and interpersonal functioning.

Self-functioning includes a person's sense of identity, self-esteem, ability to set meaningful goals, emotional regulation, and self-reflection. Interpersonal functioning involves empathy, desire for closeness, and the capacity to maintain mutually beneficial relationships. The study involved 335 adults seeking individual psychotherapy, recruited from four mental health outpatient centers in Santiago, Chile.

Participants completed surveys assessing their early life experiences, current personality functioning, and anxiety levels. Childhood maltreatment was measured by rating the frequency of different forms of abuse and neglect. Personality functioning was assessed through self-reports on self-perception, emotional regulation, and relationship dynamics.

The researchers evaluated participants for generalized anxiety disorder using a standard symptom checklist. The analysis revealed that 64.2% of participants had experienced at least one type of childhood maltreatment, with emotional abuse being the most common (43%). Women were more likely to report histories of sexual abuse. The study found that 64.2% of participants had experienced at least one type of childhood maltreatment, with emotional abuse being the most common (43%).

Both self-functioning and interpersonal functioning were significantly impacted by early maltreatment, accounting for roughly 73% of the relationship between childhood maltreatment and adult anxiety. Self-functioning impairments had a slightly larger impact than interpersonal functioning. Emotional abuse specifically showed a larger effect on self-functioning impairments, particularly in self-perception and emotional regulation.

The findings suggest that personalized therapeutic strategies could better address the lasting effects of early trauma by targeting these specific personality impairments.
