A randomized trial of a group cognitive intervention for preventing depression in adolescent offspring of depressed parents.

BACKGROUND: Adolescent offspring of depressed parents are at high risk for development of depression. Cognitive restructuring therapy holds promise for preventing progression to depressive episodes. METHODS: A randomized, controlled trial was conducted to prevent depressive episodes in at-risk offspring (aged 13-18 years) of adults treated for depression in a health maintenance organization (HMO). Potential adult cases were found by reviewing the HMO pharmacy records for dispensation of antidepressant medication and the mental health appointment system. Medical charts were reviewed for a depression diagnosis. Recruitment letters signed by treating physicians were mailed to adults. Eligible offspring had subdiagnostic depressive symptoms insufficient to meet full DSM-III-R criteria for affective disorder and/or a past mood disorder. These youth were randomized to usual HMO care (n = 49) or usual care plus a 15-session group cognitive therapy prevention program (n = 45). RESULTS: We detected significant treatment-by-time (program) effects for the Center for Epidemiological Studies Depression Scale (P=.005) and the Global Assessment of Functioning scores (P =.04). Survival analysis of incident major depressive episodes during a median 15-month follow-up found a significant advantage (P =.003) for the experimental condition (9.3% cumulative major depression incidence) compared with the usual-care control condition (28.8%). CONCLUSION: A brief, group cognitive therapy prevention program can reduce the risk for depression in the adolescent offspring of parents with a history of depression.

Corticotropin releasing hormone increases apparent potency of adrenocorticotropic hormone stimulation of cortisol secretion.

HYPOTHESIS: Corticotropin releasing hormone (CRH) has a regulatory effect on cortisol secretion in addition to its classic effect of stimulating adrenocorticotropic hormone (ACTH) secretion. REVIEW: There is growing evidence of "long-loop" and paracrine adrenal stimulation by CRH. Data from a study of the ovine-corticotropin releasing hormone (oCRH) stimulation test in 13 sexually abused girls and 13 normal controls was used in Montecarlo simulations of the hypothalamic-pituitary-adrenal axis, to get estimates of adrenal sensitivity to ACTH and cortisol elimination kinetics before and after oCRH administration. In both controls and sexually abused girls, ACTH had an apparent greater effect on cortisol secretion after administration of oCRH compared to its effect during the baseline period. This lends support to the hypothesis and suggests that it should be tested experimentally.

Using 'off the shelf', computer programs to mine additional insights from published data: diurnal variation in potency of ACTH stimulation of cortisol secretion revealed.

We describe the use of available computer programs to mine additional insights from published data. Graphs from four studies of ACTH and cortisol plasma levels collected throughout the 24 h day in humans were scanned into digital form and the data points extracted. To investigate the magnitude of ACTH stimulation of cortisol secretion across the 24 h, Monte Carlo methods were used to fit the parameters of a computer model of the ACTH-adrenal axis to the extracted data. ACTH was found to have a greater effect on cortisol secretion during the peaks of the cycle than at the nadir. This finding could not be explained by previously published dose response curves of ACTH effect. This implies that other modulators influence the effect of ACTH on the adrenal. This study also demonstrates how available computer programs can be used to examine models of physiologic regulation using data already available in the literature.

Clinical course and outcome of substance abuse disorders in adolescents.

Seven percent (19 of 275) of children and adolescents not ascertained for seeking treatment received a DSM-III diagnosis of alcohol or drug use disorder. Their entire families were recruited into a research program designed to study the risk to offspring of parental psychopathology. The ages of those diagnosed were between 12 and 18 years. The drug and alcohol use disorders had a mean duration of 2 years, and the adolescents who remitted had a high likelihood of developing subsequent psychopathology. These adolescents also showed high rates of other psychiatric disorders. A high rate of alcoholism was found among their parents.

Mental health of adolescent mothers: the implications of depression and drug use.

Childbearing and child rearing during adolescence result in poor health and psychosocial outcomes for some mothers and their children. Whereas the mental health problems of adolescent mothers are common in clinical experience, they are infrequently investigated and discussed in the literature. Mental health problems such as depression and/or drug use may be key factors in determining which mothers and their children will have poor outcomes. The purpose of this paper is to explore how depression and drug use may affect the health and development of adolescent mothers and their children. Because of their relevance to adolescent motherhood, this paper brings together information from three research areas: adolescent depression, adolescent drug use, and maternal depression.

Evaluating ego defense mechanisms using clinical interviews: an empirical study of adolescent diabetic and psychiatric patients.

Ego defense mechanisms were studied in three groups of early adolescents: diabetic patients, non-psychotic psychiatric patients, and healthy high school students. Defenses were assessed from ratings of open-ended, in-depth interviews. High levels of denial and low levels of asceticism were found in all three groups. Comparisons between groups indicated that psychiatric patients had a distinctive profile of defense usage, in comparison to adolescents from the other two groups. An independent measure of ego development was positively correlated with the defenses of altruism, intellectualization, and suppression, while it was negatively correlated with acting out, avoidance, denial, displacement, projection, and repression. The findings of substantial differences in defense usage between the psychiatric and non-psychiatric samples, and the size and directions of the correlations with ego development level, lend support to the validity of the defense codes.

Course of major depression in non-referred adolescents: a retrospective study.

This article reports on a naturalistic study of the course of illness of 38 children diagnosed as having a current or past episode of major depression out of a sample of 275 children who were selected by a method not related to their psychopathology or treatment-seeking behavior. Assessments of the presence of depression and the course of this disorder were made using structured clinical interviews (DICA and DICA-P) and a criterion-based diagnostic system (DSM-III). Longitudinal methods of data analysis included the use of life tables. The proportion of children depressed for 2 years closely resembles the results found in investigations of children who sought treatment for a psychiatric disorder. The probability of remaining depressed in these children was 21% at 1 year after onset, and 10% at the 2-year point. This parallels the rate of chronicity and the decline in rates of recovery which occur over time in adult depression.
