Over 15 million people participated in racial justice protests nationwide during 2020-2021 spotlighting activism as a collective tool against structural racism and discrimination (SRD). SRD manifests as policies and practices (e.g., redlining, voter suppression, mass incarceration) that produce hostile environments that contribute to psychological distress, elevated allostatic load, and an elevated risk for chronic diseases and premature death, concentrated within Black and Latinx populations. While the connection between SRD and health is well documented, few studies provide evidence on strategies to reduce SRD and mitigate consequences on psychological and physiological outcomes. Thus, there is a critical need to rigorously test interventions that improve the mental and physical health of Black and Latinx populations, beginning in adolescence. The study's specific aims are to 1) Determine whether a racial justice activism behavioral intervention prevents and reduces depressive symptoms in Black and Latinx adolescents and young adults and 2) Determine whether a racial justice activism behavioral intervention lowers allostatic load scores in Black and Latinx adolescents and young adults. To accomplish these aims, the team will conduct a stage II group-based, multi-component, and multilevel randomized behavioral clinical trial. The investigators will collect psychological and physiological measures at baseline, then at defined intervals for 2 years post the racial justice activism intervention.

The goal of this clinical trial is to adapt a sleep intervention for individuals representative of all demographic groups, including those who are at the highest risk for suicidal behavior. Sleep difficulties are a promising target for youth with suicidal thoughts and behavior to focus on as a prevention measure. We aim to increase intervention acceptability and impact by adapting it for the adolescent populations at highest risk for suicidal thoughts and behavior. The research project will compare Transdiagnostic Sleep and Circadian Intervention (TranS-C), an evidence based, modularized intervention that targets a range of sleep difficulties to a treatment as usual or control condition including providing weekly sleep feedback reports from data entered into a daily sleep diary and from wearing a sleep sensing, actigraphy watch. Participants in both conditions (TranS-C vs. Sleep Feedback) will wear an actigraphy sleep watch that monitors sleep, and complete daily sleep diaries via smartphone or email. Participants in the TranS-C condition will also wear bright light (BL) and blue blocking glasses each day as well as attend weekly or biweekly sessions with a Sleep Therapist. The sleep therapist will review sleep feedback during sessions.

The purpose of this research study is to evaluate different depression treatment approaches among cancer survivors. A cancer survivor is defined as anyone who is living and has been diagnosed with cancer. Participants will be randomly assigned to either receive a mobile app for depression treatment, called "Moodivate", or to receive telehealth depression treatment sessions. Approximately 2/3 of participants enrolled will receive the mobile app and the remaining 1/3 will receive depression treatment via telehealth. Participants that receive Moodivate may later be assigned to also receive depression treatment via telehealth based their response to the Moodivate app. Participants will be asked to either use the Moodivate app and/or receive depression treatment via telehealth for a period of 10 weeks. All participants will be asked to electronic questionnaire measures throughout the study period. Questionnaires will assess symptoms of depression, as well as general experiences using Moodivate and participating in this trial. Participation in this study will take about 24 weeks. Participation in this study may help improve options for emotional wellness for cancer survivors. The greatest risks of this study include frustration, worsening of emotional distress, data breach, and/or loss of confidentiality.

The U.S. Deaf community - a group of more than one million Americans who communicate using American Sign Language (ASL) - experiences nearly triple the rate of lifetime problem drinking and twice the rate of trauma exposure compared to the general population. Although there are several treatments for alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) in hearing populations, none have been developed for or tested with Deaf clients. To address these barriers, the study team developed Signs of Safety, a Deaf-accessible therapy toolkit for treating AUD and PTSD. Their aims are to conduct a nationwide, virtual clinical trial to compare (1) Signs of Safety with (2) treatment as usual and (3) a no treatment control, to collect data on clinical outcomes, and to explore potential mediators and moderators of outcome.

This protocol will test the effectiveness of an intervention, iCHART (integrated Care to Help At-Risk Teens) and facilitate recruitment for other studies in the larger ETUDES Center grant, which are focused on treatment development for target risk factors for suicidal behavior, specifically, sleep, anhedonia, and stress related to cybervictimization. This study will recruit 900 adolescents which will be enrolled in a randomized controlled trial to test iCHART and will be randomized to iCHART or treatment as usual (TAU). Based on previous work, the investigators hypothesize that iCHART, compared to TAU, will decrease suicidal-related events by 50%, and the effects will be mediated by increases in referrals, treatment engagement, and safety planning. The investigators will use implementation science methods to assess contextual factors (i.e., barriers and facilitators) and implementation outcomes specifically, acceptability, feasibility, appropriateness, and cost for our predictive algorithm and iCHART to inform future implementation efforts and promote health equity.

Bipolar disorder is a severe chronic mood disorder that affects up to 4% of the adult population and 1.8% of the pediatric population in the United States. The treatment of the depressive episodes of bipolar disorder in the pediatric population has not been as widely studied as the treatment of depressive episodes in bipolar disorder in adults, therefore pharmacotherapeutic options are limited. Given the change in disease state and safety demonstrated in adults with depressive episodes associated with bipolar I disorder, the purpose of this study is to evaluate the change in disease state and safety of cariprazine in the treatment of depressive episodes associated with bipolar I disorder in the pediatric population. Cariprazine is an approved drug for the treatment of depressive episodes in adult participants with bipolar I disorder. Study doctors put participants in 1 of 2 groups, called treatment arms. There is a 1 in 2 chance that a participant will be assigned to placebo. Around 380 Participants ages 10-17 years with bipolar I disorder will be enrolled in approximately 60 sites worldwide. Participants receiving the study drug will receive Dose A or B of Cariprazine based on age and weight. At Week 3, participants with insufficient response will have their dose increased to Dose B or Dose C, while participants with sufficient response will continue receiving the Dose A or B for the remainder of the treatment period. The treatment period will be followed by a safety follow-up (SFU) period for 4 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular weekly visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
