Musso, Giovanna (5/08) The parental bond and adverse childhood experiences as predictors of maladaptive personality traits in adulthood (Nicholas Papouchis, Ph.D.; Lisa Samstag, Ph.D.; David Castro Blanco, Ph.D.)

The present study examined the contribution of an inadequate parental bond and adverse childhood experiences as predictors of maladaptive personality traits in a non-clinical college population consisting of 187 student-participants and 126 of their parents. All measures were self-report questionnaires: the Wisconsin Personality Disorders Inventory measures personality traits from the 11 personality disorders on a dimensional scale; the Parental Bonding Instrument measures two factors of the parental bond, namely care and overprotection; and the Childhood Trauma Questionnaire measures trauma of different types, such as emotional neglect, emotional abuse, physical abuse, and sexual abuse. Hierarchical multiple regression analyses were conducted to test the major hypothesis. Results indicated that an inadequate parental bond and the childhood trauma factors were indeed statistically predictive of personality traits in all three clusters (A, B, and C) as well as a total personality score; after controlling for covariates, these results were modest. Emotional abuse emerged as the only significant independent predictor of these personality traits. Correlational analyses showed that both perspectives of the parental bond--student-participant reports and parent-participant reports--were significantly consistent. A significant relationship was also found between a total childhood trauma score and each of the three personality clusters. These results are discussed in relation to relevant theoretical and empirical literature and other exploratory analyses are presented. Given some of the modest results, other possible contributors to personality dysfunction are explored and recommendations for future research provided.
