Adolescent anhedonia is a multidimensional construct defined as the loss of enjoyment or pleasure across multiple domains of life. Anhedonia is concurrently associated with substantial impairment and distress, and it prospectively predicts the onset, severity, and treatment of depression. Despite its demonstrated importance, a limited number of…

The present study investigated child depression symptoms, social skills, and mother-child conflict from mid-childhood to mid-adolescence. Bidirectional effects involving all three constructs were anticipated, as were differential effects for child gender. Participants included 893 families from the Study of Early Child Care and Youth Development…

Depression is common among autistic youth and is associated with worse quality of life in this group. Despite significant need for high-quality efficacious treatments, there has been very limited research on interventions for depression in autistic youth. This single-arm pilot study examined the feasibility and preliminary efficacy of a novel,…

The main aim of this study was to examine one potential mediator of the prospective association between depressive symptoms and peer victimization: sadness rumination. Data were collected from 302 early adolescents (M[subscript age] = 10.53, SD =0.16; 55.3% girls), at two waves, 1-year spaced, using self-reports. Depressive symptoms preceded…

This study examined the extent to which early cumulative risk predicts a range of behavioral and psychological outcomes (i.e., depression, future orientation, risky behavior, educational attainment, and socioeconomic outcomes) measured at ages 15 and 26 and whether executive function (EF) and/or behavioral regulation mediated and/or moderated…

Negative self-esteem is an important transdiagnostic factor underlying various youth psychological problems. Most studies so far have examined the role of more conscious, explicit self-esteem, assessed with self-report questionnaires. Our study investigated the role of explicit as well as implicit self-esteem (with Rosenberg's self-esteem scale…

This study investigated the relationship between mathematics difficulties and psychopathology in a large community sample (N = 881) of youth (8-18 years of age) in the United States. The primary aims of the study were to (a) test the associations between mathematics difficulties and specific components of internalizing, externalizing, attention,…

Purpose: This study investigated the complexity of stuttering behavior. It described and classified the complexity of stuttering behavior in relation to age, behavioral treatment outcomes, stuttering severity, anxiety-related mental health, impact of stuttering, and gender. Method: For this study, a taxonomy was developed--LBDL-C7--which was based…

Adolescent depression is a major concern for public health and is associated with negative consequences and outcomes. Identifying adolescent characteristics that might relate to the risk for developing depression is crucial. This study investigated bidirectional associations between coping strategies and depressive symptoms over time. The…

To examine whether trajectories of participation in organized activities during the high school years and beyond (from ages 14 to 20) predicted outcomes at age 21 (externalizing problems, internalizing problems, civic engagement, number of years of education, and perception of physical health), 354 youths (60% girls) were surveyed annually over…

Although a considerable body of research has documented the association between victimization experience and adolescent mental health, previous studies have not investigated the mediating effects of personality characteristics such as social competence and self-mastery on the associations between cyberbullying victimization and mental health. This…

Recent theory and evidence support an integrated affective-cognitive model of adolescent depressive symptoms in which temperament predicts the use of maladaptive cognitive emotion regulation (ER) strategies which, in turn, predict depressive symptoms. We concurrently and prospectively investigated whether two cognitive ER strategies (dampening and…

Adolescence is a critical period for social development, which COVID-19 has dramatically altered. Quarantined youths had limited in-person interactions with peers. The present study used an intensive longitudinal design to investigate changes in interpersonal dynamics and mental health during COVID-19. Specifically, we investigated whether the…

The aim of this research study was to examine the effects of Assisted Cycling Therapy (ACT) on adaptive/maladaptive behaviors, depression, and self-efficacy in adolescents with Down syndrome (DS). The participants were counterbalanced to either intervention groups of 1) Assisted Cycling Therapy (ACT), in which the participants' voluntary pedaling…

The formation of a stable identity, consisting of a strong set of commitments, is a key developmental task in adolescence and young adulthood. Not resolving this task and lacking strong identity commitments is related to difficulties like depressive symptoms and stressful life events. However, the exact role of identity commitments in these…
