PID-5 Trait Indicators of Emotional Instability and Childhood Adversity Antecedents

Personality traits provide natural mechanisms through which childhood maltreatment may translate into psychiatric symptomatology. The PID-5 has provided a DSM-supported exemplar for canvassing traits that may contribute to the developmental trajectories of many personality and mood disorders. This general population survey (N = 2,430) examined associations between adverse childhood experiences (ACE questionnaire) and selected PID-5 trait indicators of emotional well-being (Depressivity, Anxiousness, and Emotional Lability). These associations were contrasted with others derived from traditional dimensional measures of childhood maltreatment. ACE counts and all six of the dimensional maltreatment indicators were linked to the three trait scores. Family emotional abuse and ACE counts provided equally strong correlates of Depressivity and Anxiousness. ACE counts and childhood sexual abuse were especially strong in their associations with all three traits. Graded relationships were found in these trait-adversity relationships with polyvictimized respondents generating the highest personality maladjustment. The odds of a trait score elevation (>1 SD) were raised substantially (two to five fold) by singular adversity exposures, and the co-occurrence of only two different forms of adversity maximized odds of extreme trait expression. These results contribute to an evidentiary base suggesting steeper developmental trajectories for personality maladjustment among maltreated youth.
