High rates of nonsuicidal self-injury (NSSI; 14%-17%) in adolescents and young adults suggest that some self-injurers may exhibit more or different psychiatric problems than others. In the present study, the authors utilized a latent class analysis to identify clinically distinct subgroups of self-injurers. Participants were 205 young adults with a history(More)
This study examined associations between temperament at age 3 and depressotypic cognitive styles at age 7 in a community sample of children. Sixty-four preschool aged children were assessed for positive emotionality (PE) and negative emotionality (NE) using a standardized battery of laboratory tasks and naturalistic home observations. At follow-up 4 years(More)
We aim to provide a starting point toward the development of an evidence-based assessment of depression in children and adolescents. We begin by discussing issues relevant to the diagnosis and classification of child and adolescent depression. Next, we review the prevalence, selected clinical correlates, course, and treatment of juvenile depression. Along(More)
Margaret Dyson for help with data collection. Thanks also to the families who participated in this study. This study examined associations between temperament at age 3 and maternal reports of youths' depressive symptoms at ages 7 and 10. Fifty-three preschool aged children were assessed for positive emotionality (Pe) and negative emotion-ality (Ne) using(More)
OBJECTIVE This study examines relationships between affect and sleep in youth with affective disorders using ecological momentary assessment (EMA). METHODS Participants included 94 youth, ages 8-16 (M = 11.73, 53% female) years with an anxiety disorder only (n = 23), primary major depressive disorder (with and without a secondary anxiety diagnoses; n =(More)
This study aimed to characterize affective functioning in families of youth at high familial risk for depression, with particular attention to features of affective functioning that appear to be critical to adaptive functioning but have been underrepresented in prior research including: positive and negative affect across multiple contexts, individual and(More)
A key component of temperament models is the presumed temporal stability of temperament traits. Although a substantial literature using parent report measures has addressed this claim, very few investigations have examined the stability of temperament using alternative measurement strategies, particularly those that involve direct assessment of emotional(More)
Major Depressive Disorder (MDD) in adolescents is characterized by alterations in positive emotions and reward processing. Recent investigations using functional magnetic resonance imaging (fMRI) find depression-related differences in reward anticipation. However, it is unknown whether feedback influences subsequent reward anticipation, which may highlight(More)
This study used person-oriented analyses to identify subgroups of individuals who exhibit different patterns of depressive and anxiety disorders over the course of adolescence and young adulthood. Using latent class growth analysis, six trajectory classes were identified. Two classes were mainly characterized by depressive disorders; one class was mainly(More)
Adolescent development encompasses an ostensible paradox in threat processing. Risk taking increases dramatically after the onset of puberty, contributing to a 200% increase in mortality. Yet, pubertal maturation is associated with increased reactivity in threat-avoidance systems. In the first part of this paper we propose a heuristic model of adolescent(More)
