Very Young Child Well-being in Military Families: A Snapshot

Since the September 11th attacks on the U.S., more than 2 million children have experienced parental deployment during their early years, with potentially lasting impact. When a parent is deployed, a number of factors may affect the well-being of the service member and his/her family. One parental factor—posttraumatic stress disorder or distress—might be particularly powerful in its effect on young children and the family system. We analyzed baseline data from an intervention development project which focused on supporting military families with very young children during post-deployment. The purpose of this research is to understand the relationships between parental mental health status, parenting stress, couple functioning, and young child well-being. The effects of mental health status of home-front and service member parents and the role of couple functioning on parent–child interactions and behavioral problems of young children were examined in a sample of military families during the post-deployment period. Findings suggest that service member posttraumatic stress symptoms are associated with higher parental report of child behavior problems. Higher quality of the couple relationship appears to lessen the impact of parental posttraumatic stress but is not related to parent perceptions of child behavior concerns. Implications for future research with military families are discussed.     

Outcome and epidemiological research on personality disorders: implications for classification

The construct of personality disorder has an overall definition that describes chronicity. However, the findings of outcome research indicate that while many patients stop meeting criteria for specific categories of disorder over time, they often continue to suffer from dysfunctional traits. One can also interpret epidemiological findings on personality disorders as overestimating disorders due to a failure to distinguish them from traits. Taken together, these findings point to the need for a revision of the classification of personality disorders that would separate enduring traits from reversible symptoms.     

Neurobiological dimensional models of personality: a review of the models of Cloninger, Depue, and Siever

Neurobiological dimensional models of personality aim to account for the structure of personality traits and disorders through links to neurotransmitter systems. Three such models are reviewed: those of Cloninger, Depue, and Siever. While these proposals have heuristic value, none of them has obtained strong empirical support. Our current understanding of neurobiology is insufficient to develop a model of personality on this basis. At this point, dimensions of personality should be derived from factor analysis rather than from neurobiological theories.
