Depression and Axis II symptomatology in an adolescent community sample: concurrent and longitudinal associations

The relationship between personality pathology and depression has been the focus of increasing attention, but few investigators have examined this issue prospectively or in adolescent community samples. The present study used both self report and interviewer assessments of personality disorder symptomatology and depression in a sample of 155 late adolescent women followed over three years. Personality pathology cluster and total scores demonstrated moderate to fairly high degrees of stability, indicating endurance of these traits in late adolescence. As predicted, Axis II symptoms were associated with concurrent depressive symptomatology. Overall, self-reported personality disorder symptoms, as well as those specifically in Clusters A and B, predicted interviewer-rated depression over two years beyond the contribution of initial depression, indicating that subclinical Axis II symptoms are a risk factor for subsequent depressive symptomatology.

Predictors of the generation of episodic stress: a longitudinal study of late adolescent women

The effects of depression and Axis I comorbidity on subsequent self-generated life stress were examined in a longitudinal sample of 134 late adolescent women. The results indicated that specific forms of psychopathology constitute a risk factor for future self-generated episodic stress, even when controlling for prior chronic stress. Comorbid depression had a particularly salient effect in the prediction of stress related to interpersonal conflicts. The effects of family psychopathology and sociotropy were mediated through participant psychiatric status, whereas autonomy made an independent contribution to the prediction of episodic stress. These results support C. Hammen's (1991b) stress generation model in a community sample, demonstrating how individuals with depression play a role in the creation of stress, and also refine prior work by showing that only the comorbid form of depression is associated with subsequent conflict-related stress.

Neuropsychological deficits in abstinent cocaine abusers: preliminary findings after two weeks of abstinence

Sixteen subjects hospitalized for treatment of cocaine dependence were administered a battery of neuropsychological tests within 72 h of last cocaine use and again approximately 2 weeks later. Twenty-one non-cocaine using control subjects, matched for age, gender, ethnicity and education, also received neuropsychological testing. Abstinence from mood altering substances during the 2-week study period was verified for both groups on three occasions using quantitative urine analysis. The results suggest that recent cocaine use is associated with impairment in memory, visuospatial abilities, and concentration during the acute phase of withdrawal, independent of withdrawal-related depression. Furthermore, many of these deficits appear to persist at least 2 weeks beyond cessation of cocaine use.

Hypothalamic-pituitary function during alcohol exposure and withdrawal and cocaine exposure

This chapter examines the neuroendocrine effects of acute exposure to and withdrawal from alcohol and cocaine, with special emphasis on the hypothalamic-pituitary-adrenal (HPA) axis. We present the results from two preliminary controlled inpatient studies that document HPA dysfunction during acute exposure to alcohol and cocaine and during withdrawal from alcohol. We discuss the methodological approach of these studies in comparison to related attempts in the literature to use measures of thyroid and prolactin regulation to predict risk of relapse to alcohol and cocaine use, respectively. Our data and the results of related studies are presented in the context of a proposed index of HPA axis dysfunction that may provide a useful clinical measure of susceptibility to relapse during protracted abstinence from alcohol or cocaine.
