Background: Evidence regarding the long-term separate and combined impact of adolescent psychiatric disorder and personality disorder (PD) on physical health is absent., Method: A total of 736 people randomly selected in childhood were contacted for home or telephone interviews four times over 20 years. DSM Axis I disorders and Axis II PDs were assessed at mean age 13.7 years in 1983 and physical health was assessed in 1985-1986, 1991-1994 and 2001-2004., Results: Comparisons were made between 506 adolescents without Axis I disorder or PD and adolescents with Axis I disorder or PD or both. Adolescents with an Axis I disorder (n=150) had significantly higher odds of pain and physical illness and poorer physical health. Adolescents with a PD (n=149) had higher odds of pain and physical illness and poorer physical health and a more rapid decline in physical health. In addition, the 81 participants with an Axis I disorder without co-morbid PD had poorer physical health, but this effect did not reach statistical significance, whereas the 80 participants with a PD but no Axis I disorder reported significantly more pain and more rapid decline in physical health. However, the 69 participants with co-morbid Axis I disorder and PD had the highest rates of pain and physical illness and the worst physical health., Conclusions: Co-morbid PD accounted for many of the associations of adolescent Axis I disorder with physical health over the ensuing two decades. Co-morbid adolescent Axis I disorder and PD represent a particularly high risk for physical health.

Context: Although Axis II personality disorders in adolescence have been linked to psychopathology and psychosocial impairment in early adulthood, little is known about their effects over longer periods., Objectives: To evaluate and compare long-term prognoses of adolescent personality disorders and co-occurring Axis I disorders., Design: Population-based longitudinal study., Setting: Upstate New York., Participants: A community sample of 629 adolescents interviewed at a mean age of 13.8 years and again at a mean age of 33.2 years., Main Outcome Measures: Clinically assessed psychiatric disorders and self-reported attainment and function., Results: Axis I (mood, anxiety, disruptive behavior, and substance use disorders) and Axis II disorders in adolescence showed risks for negative prognoses lasting 20 years. Co-occurring Axis I and Axis II disorders consistently presented the highest risk, often approximating the sum of the axis-associated risk or even several times the risk of disorders in either axis alone., Conclusions: Long-term prognoses of Axis I and Axis II disorders are of comparable magnitude and often additive when comorbid. These findings are highly relevant to the current debate over how personality disorders should be handled in DSM-V.

Anxious and avoidant attachment were assessed in the Children in the Community (CIC) Study during adolescence and adulthood using self-report scales developed for this prospective study. The convergent and discriminant validity of the new CIC attachment scales were evaluated and their stability was assessed across a 17-year interval. Attachment scales predicted DSM-IV personality disorders in theoretically coherent and clinically meaningful ways, especially when supplemented with a separate measure of interpersonal aggression. Cluster B and C personality disorder symptoms were associated with elevated anxious attachment. Avoidant attachment was positively associated with Cluster A symptoms and inversely associated with Cluster B and C symptoms. Interpersonal aggression was higher in Cluster B symptoms and lower in Cluster C symptoms, thus differentiating between these symptom clusters.
