The goal of this neuroimaging pilot study is to understand developmental differences in the impact of therapeutic wavelength light (blue light) versus a non-therapeutic wavelength (red light) on emotional brain function in depression. The main questions this study aims to answer are: * Does acute exposure to blue light (vs red light) stabilize emotional brain function in depressed individuals? * Are stabilizing effects of blue light (vs red light) stronger for blue light in adolescents than young adults? Participants will complete: * A magnetic resonance imaging brain scan, in which we will examine the effect of blue versus red light on emotional brain function at rest and in response to rewards and losses. * A pupillometry test of sensitivity to blue vs red light * Clinical interviews and surveys * Screening measures for drug and alcohol use, MRI safety, and current pregnancy \[if relevant\] * Home sleep tracking with sleep diary and actigraphy for one week
Depression in youth is a serious public health concern for which more personalized treatments are needed. This randomized controlled trial will test the effect of an intervention aimed at enhancing social cognitive capacities (e.g., ability to take another's perspective), thereby making treatment of depression in youth more efficient and effective. Participants in the R33 (N=82) will be youth between ages 13- through 17-years-old currently experiencing depression. Youth will be randomized to either an enhanced CBT intervention that teaches social cognitive skills, particularly social perspective taking and theory of mind (CBTSCT) as compared to CBT only. The primary target is improvement in both social cognitive skills and depressive symptoms at post-treatment and at a 6-month follow-up.
The primary objective will be to study changes in putamen connectivity and depression severity in depressed teens with meditation training. H1: Putamen node strength will increase in the training group compared to the active controls. H2: This increase in node strength will correlate with practice amount recorded by participants. H3: There will be a significant reduction in self-rated depression symptoms following the training as measured by the Reynolds Adolescent Depression Scale (RADS-2), compared to controls. H4: This reduction will correlate with the increase in putamen node strength. Design and Outcomes: The current research study design will utilize an individually randomized group treatment, open-label, active-controlled clinical trial to test the efficacy and safety of the investigator's innovative mindfulness meditation intervention (Training for Awareness Resilience and Action \[TARA\]) on the primary outcome (Putamen structural node strength) and secondary outcome (depression symptoms measured using Reynolds Adolescent Depression Scale \[RADS-2\]) in depressed adolescents between the ages of 14 to 18 years old.
This study is dedicated to help identify biomarkers for depression and suicide. The purpose of the study is to better understand these links to improve medical and psychiatric care in the future. This research is also to test the effects of standard treatment of depression on improvement in depressive and suicidal behavior and on biomarkers (e.g. miRNA) for these disorders.
This double-blind, placebo-controlled clinical trial will examine the effect of probiotic Visbiome on the brain and gut microbiome of individuals 15 to 24 years of age.
The goal of this interventional study is to compare the baseline neural mechanisms and parenting in depressed and non-depressed children and to examine baseline neural mechanisms and parenting as predictors of Family-Focused Treatment for Childhood-Depression (FFT-CD) outcomes. The main questions it aims to answer are: * What are differences between depressed and non-depressed participants on baseline neural and parenting indicators? * Do baseline neural and parenting indicators predict response to FFT-CD? * Does change in parenting and neural functioning mediate change in depression from baseline to follow-up? Participants will: * complete baseline clinical measures * complete neuroimaging tasks via Functional Magnetic Resonance Imaging (fMR) * undergo a 12-session course of FFT-CD * complete follow up evaluations and neuroimaging
The overall goal of this study is to develop an mHealth intervention (Suubi-Mhealth) for use among Ugandan youth (14-17 years) with comorbid HIV and depression, taking into account their unique contextual, cultural, and developmental needs. This digital therapy intervention delivered via a mobile application, will utilize the core tenets of cognitive-behavioral therapy (CBT) found to improve depression and ART adherence.
Despite experiencing higher rates of depressive symptoms (Center for Disease Control and Prevention, 2020) and similar rates of Major Depressive Disorder (MDD; Substance Abuse and Mental Health Services Administration (SAMHSA), 2019), Latino adolescents in the U.S. are significantly less likely than their non-Latino White peers to receive treatment for MDD (SAMHSA, 2019). The purpose of this study is to identify a stakeholder-preferred implementation strategy that may improve psychotherapy attendance among Latino adolescents. Latino adolescent-parent dyads and healthcare providers will be recruited from healthcare settings and social media. Focus groups will be conducted with healthcare providers (n=5), and individual interviews will be conducted with Latino adolescents with a diagnosis of depression (n=15) and their parents (n=15).
Lack of perceived control, particularly during stress, has been critically implicated in major depressive disorder (MDD) and anhedonic symptoms, especially among female adolescents; yet the neural underpinnings of perceived control disruptions in MDD remain poorly understood. Using functional magnetic resonance imaging with a novel "value of control task" in conjunction with a prospective design, this study will provide a comprehensive understanding of stress and perceived control related mechanisms in female adolescents with MDD and will examine stress-induced disruptions in perceived control as a predictor of "real world" expressions of maladaptive coping and anhedonia.
This study will evaluate whether a newer treatment, rumination-focused cognitive behavioral treatment, which includes mindfulness and can be used to reduce ruminative habits, change ways in which key brain regions interact with each other (e.g.., often called connectivity), and whether these changes in habits and brain connectivity can reduce the risk for recurrence of depression in the next two years.
