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)
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)
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)
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)
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)
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)
BACKGROUND Serotonin transporter promoter (5-HTTLPR) genotype appears to increase risk for depression in the context of stressful life events. However, the effects of this genotype on measures of stress sensitivity are poorly understood. Therefore, this study examined whether 5-HTTLPR genotype was associated with negative information processing biases in(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)
Adolescence is a developmental period characterized by significant increases in the onset of depression, but also by increases in depressive symptoms, even among psychiatrically healthy youth. Disrupted reward function has been postulated as a critical factor in the development of depression, but it is still unclear which adolescents are particularly at(More)
Item response theory (IRT) methods allow for comparing the utility of instruments based on the range and precision of severity assessed by each instrument. As adolescents and young adults can display rapid increases in depressive symptoms, there is a crucial need to sensitively assess mild elevations of symptoms (as an index of initial risk) and(More)
