What factor is most associated with the onset of GAD?

The factor most associated with the onset of Generalized Anxiety Disorder (GAD) is adverse childhood experiences. Research indicates that individuals who have encountered negative or traumatic experiences during childhood—such as abuse, neglect, or significant family disruptions—are at a higher risk for developing various mental health issues, including anxiety disorders like GAD. These experiences can contribute to altered brain development and impact emotional regulation, making individuals more vulnerable to anxiety later in life.

Adverse childhood experiences can lead to a heightened sense of threat, increased sensitivity to stress, and learned behaviors that contribute to excessive worrying and anxiety. Consequently, early trauma can establish a foundation for the development of GAD in adulthood, as individuals may carry forward maladaptive coping mechanisms and heightened anxiety responses from their formative years. Understanding this connection helps in creating targeted interventions and support systems for those affected.
