Research on Outpatient Adolescent Treatment for Comorbid Substance Use and Internalizing Disorders
Adolescent substance abuse results in significant negative outcomes and extraordinary costs for youths, their families, communities, and society. Moreover, rates of psychiatric comorbidity among substance abusing youth range from 25% up to 82%, and youths with a dual diagnosis are more than twice as costly to treat compared to those with no comorbidity. The applicant principal investigator recently completed a pilot project funded by the National Institute on Drug Abuse focused on developing and piloting a psychosocial treatment specifically for youth presenting for outpatient treatment with co-occurring substance use and internalizing (i.e., mood and/or anxiety) problems. Results were promising with the experimental group exhibiting significantly less substance use and more rapid reductions in anxiety and depressive symptoms compared to the control group. The proposed research is a randomized clinical trial (RCT) to compare the experimental treatment (OutPatient Treatment for Adolescents; OPT-A) to an "active placebo" on key clinical indices from pre-treatment through 18 months. The proposed RCT (n = 160) employs the treatment manual, quality assurance protocol, and therapist training protocol developed and successfully tested in the pilot study, to evaluate the efficacy of OPT-A for youth referred to outpatient treatment of co-occurring substance use and internalizing problems. The following outcomes will be evaluated: drug use; mental health; behavioral, school, peer, and family functioning; and consumer satisfaction. The intervention addresses one of the more prevalent and most challenging, costly, and understudied presenting problems among adolescent outpatients. If successful, this research could provide a considerable contribution in the treatment field for youth with co-occurring substance use and internalizing disorders.

Feasibility Study of UP-A-AST Parent Group for Adolescents With Autism and Co-occurring Anxiety/Depression
Autism spectrum disorder (ASD) is associated with high rates of psychiatric comorbidity, particularly anxiety and depressive disorders, which contribute to significant impairment for affected youth and their families. Although cognitive behavioral therapy (CBT) is recommended as a first-line treatment for anxiety and depression in children and adolescents, there is a lack of evidence-based interventions specifically adapted for youth with ASD and co-occurring emotional disorders. The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Children and Adolescents (UP-C/UP-A) is a CBT-based intervention targeting shared mechanisms underlying anxiety and depression. A parent-mediated adaptation, the Unified Protocol-Adolescent Autism Parent Group (UP-A-AST), has been developed to address the specific needs of adolescents with ASD and co-occurring anxiety and/or depressive disorders. Preliminary quality improvement work has shown promising results. This study aims to evaluate the feasibility, acceptability, and preliminary effects of the UP-A-AST Parent Group in a child and adolescent outpatient psychiatric setting. The study will include parents of adolescents aged 12-17 years with ASD and co-occurring anxiety and/or depressive disorders. Outcomes include changes in adolescents' psychiatric symptoms and functional impairment, as well as parents' perceived parenting competence. Additionally, parents' experiences of participating in the intervention will be explored.

Integrating a Stepped Care Model of Screening and Treatment for Depression Into Malawi's National HIV Care Delivery Platform
Malawi is a low-income country in sub-Saharan Africa that has limited resources to address a significant burden of disease-including HIV/AIDS. Additionally, depression is a leading cause of disability in the country but largely remains undiagnosed and untreated. Lack of cost-effective, scalable solutions is a fundamental barrier to expanding depression treatment. Against this backdrop, one major success has been the scale-up of a network of more than 700 HIV clinics, with over half a million patients enrolled in ART. As a chronic care system with dedicated human resources and infrastructure, this presents a strategic platform for integrating depression care, and responds to a robust evidence base outlining the bi-directionality of depression and HIV outcomes. The investigators will evaluate a stepped model of depression care that combines group-based Problem Management Plus (group PM+) with antidepressant therapy (ADT) for 420 adults with moderate/severe depression in Neno District, Malawi, as measured by the Patient Health Questionnaire-9 (PHQ-9). Rollout will follow a stepped-wedge cluster randomized design in which 14 health facilities are randomized to implement the model in five steps over a 15-month period. Primary outcomes (depression symptoms, functional impairment, and overall health) and secondary outcomes (e.g. HIV: viral load, ART adherence; diabetes: A1C levels, treatment adherence; hypertension: systolic blood pressure, treatment adherence) will be measured every three months through 12-month follow-up. The investigators will also evaluate the model's cost-effectiveness, quantified as an incremental cost-effectiveness ratio (ICER) compared to baseline chronic care services in the absence of the intervention model. This study will conduct a stepped-wedge cluster randomized trial to compare the effects of an evidence-based depression care model versus usual care on depression symptom remediation as well as physical health outcomes for chronic care conditions. The investigators will also look at the indirect effects of the intervention at the household level. The investigators' hypothesis is that the intervention will be effective at reducing depression symptoms, improving physical health, and improving household members' wellbeing, compare to treatment as usual. The investigators also hypothesize that the intervention will be highly cost-effective, meaning that the cost per QALY gained will be less than Malawi's median GDP per capita. If determined to be effective and cost-effective, this study will provide a model for integrating depression care into HIV clinics in additional districts of Malawi and other low-resource settings with high HIV prevalence.

Depressed Mood Improvement Through Nicotine Dosing-3 (Depressed MIND3) Extension
Deficits in cognitive control are core features of late-life depression (LLD), contributing both to emotion dysregulation and problems with inhibiting irrelevant information, conflict detection, and working memory. Clinically characterized as executive dysfunction, these deficits are associated with poor response to antidepressants and higher levels of disability. Improvement of cognitive control network (CCN) dysfunction may benefit both mood and cognitive performance, however no current pharmacotherapy improves Cognitive Control Network deficits in LLD. The study examines the hypothesis that nicotine acetylcholine receptor agonists enhance Cognitive Control Network function. This effect may resultantly improve mood and cognitive performance in LLD. Small, open-label studies of transdermal nicotine (TDN) patches have supported potential clinical benefit and provided support that transdermal nicotine administration engages the Cognitive Control Network. This is an open-label, extension to the blinded Depressed MIND 3 (Depressed Mood Improvement through nicotine dosing) study. It will evaluate longer-term safety and efficacy of Transdermal Nicotine Patches for potential benefit in cognitive and depression outcomes in elderly depressed participants. Subjects complete blinded randomized trial of Depressed MIND-3 will be eligible for continuation in this extension. This extension study will consist of up to 12 weeks of treatment and a 3 -week safety follow-up period.

Adaptation of Individual Dialectical Behavior Therapy Intervention for Transdiagnostic Treatment of Emotional Disorders
Anxiety and depressive disorders, referred to as emotional disorders, have high rates of prevalence, recurrence, and functional impairment. Transdiagnostic psychotherapy targeting shared features of these disorders has recently emerged. Dialectical behavior therapy (DBT) for the transdiagnostic treatment of emotional disorders is a promising approach, as results of preliminary studies for use in a broad range of mental disorders are encouraging. Since there is a lack of research on transdiagnostic psychotherapy in Taiwan, the investigators thus propose this 3-year randomized controlled trial to test the efficacy of a modified DBT for the treatment of transdiagnostic emotional disorders and to further evaluate whether the efficacy of modified DBT differs in the specific emotional disorders. The investigators expect that patients with emotional disorders receiving modified DBT are more likely to improve clinical outcomes, functioning, and quality of life.

Whole Health in VA Mental Health: Omnis Salutis
Recent Veterans of the Afghanistan and Iraq conflicts are presenting in VA care with high rates of posttraumatic stress disorder (PTSD), depression, anxiety, and substance use disorders. Difficulties with social relationships and community reintegration are common functional impairments with these disorders. VA is transforming to a Whole Health, patient-centered system of care that will address these issues as part of health care. In a previous study, Omnis Salutis (OS) was developed with Veteran and clinician input. OS is a three-session intervention in which Veterans learn about Whole Health and practice communicating their health mission to providers and social supports. OS was shown feasible to deliver, acceptable to Veterans, and preliminarily effective at improving physical, mental, and social functioning. This study will use a large, multisite randomized controlled trial to test the impact of OS on Veterans' social and physical functioning and Veteran engagement in mental health care. Results will support broad delivery of OS throughout the VA.

A Feasibility Study of Nature-based Health Interventions for People With Mild to Moderate Anxiety, Depression and Stress
Background and aimThe increased burden on mental health both globally and nationally is a serious challenge that requires attention and action from healthcare professionals, politicians, and decision-makers. According to the report "The National Health Profile 2021" from the Danish Health Authority, the number of adult Danes (over 16 years) with a low mental health score has increased by seven percentage points from 2010-2021 and now stands at 17.4%. A significant proportion of these individuals suffer from anxiety, depression, and/or stress. This increase in people with reduced mental health has consequences both for the individual's quality of life and for society as a whole. Thus, more than 13% of the Danish population is prescribed medication for the treatment of mental illnesses, and only 28% of them are able to work while experiencing their illness.There is a growing recognition that the challenges associated with mental health cannot be solved solely through clinical treatment or medication. In order to offer citizens and patients the best possible support, it is important to look for sustainable solutions to promote mental health and ensure access to effective treatment options. Despite a significant increase in the number of published research studies on the positive impact of nature on mental health, there has not previously been developed a theoretical foundation and a comprehensive evidence base for nature-based health interventions in a Danish context, and there has been a lack of a structured and systematically developed understanding of the mechanisms of change in nature-based health interventions (NBHIs), so they can be implemented in a way that aligns with the best available knowledge in the field.In phase 1 of the project, a systematic review of the literature has been conducted. Hereby followed an extensive co-creation process, including the development of a logic model and an underlying program theory, and established collaboration with three relevant implementation partners.In phase 2 of the project, the aim was to test the feasibility of three locally adapted NBHIs in a feasibility study with up to 120 participants (40 participants per partner) at three different partners. MethodsThe locally adapted NBHIs will be tested at the Psychiatric Center Glostrup and at the Kolding and Silkeborg municipal health centers from March to November 2025. The intervention will be carried out as an interdisciplinary initiative facilitated by two healthcare professionals employed at the respective partners, who already have experience in delivering NBHIs to the target group.The NBHIs are organized according to the following structure:• Duration of the program: Minimum 10 weeks, once a week, 1.5-2.5 hours per session• Group composition: Across conditions: mild to moderate anxiety, depression, and/or stress• Group size: 8-12 participants in a closed groupIn the locally adapted programs, activities in nature are based on three main mechanisms of change (nature interaction and sensory experiences, social communities, and physical activity and movement), identified in phase 1 of the project. The healthcare professionals responsible for the programs will tailor the activities individually. All activities are designed based on a generic logic model, developed through a co-creation process.Safety plays a central role in the nature-based health interventions. All activities are planned with a focus on the participants' physical and mental well-being. Potential risks are assessed and minimized through the selection of suitable natural environments, appropriate equipment, and thorough instruction. The healthcare professionals ensure a safe environment where participants can feel comfortable, both physically and psychologically. Additionally, accessibility and any individual needs are considered, so all participants can safely engage in the activities. With this study, the results of a new treatment or examination will not be conduced (and none of the participants will receive a worse treatment offer than what currently exists). It is about investigating the feasibility of locally adapted NBHIs at three different partners who already have nature-based programs.Both quantitative and qualitative data will be collected. These will include questionnaire data, data from registration of participation by the partner, participant observation, focus group interviews with participants from the NBHIs, as well as focus group interviews with the healthcare professionals who are carrying out the NBHIs. As part of the qualitative research, experiences with and perceptions of the process, including the feasibility of the NBHI and how the participants respond to the intervention will be examended. Written consent will be obtained from the participants and healthcare professionals prior to this.

Improving Outcomes in Depression in Primary Care in a Low Resource Setting
The OptimizeD study aims to improve outcomes in depression in primary care in India. This study will randomize 1500 patients with moderate to severe depression to either psychotherapy based on behavioral activation called the Healthy Activity Program (HAP) or antidepressant medication (fluoxetine). The study has two primary objectives: 1. Use patient characteristics to generate a precision treatment rule based on baseline information for predicting in advance what works best for whom (and which patients are unlikely to respond to either treatment and should be referred to specialist care). 2. Conduct a cost-effectiveness analysis by comparing relative costs and effectiveness between those who were randomly allocated to their optimal treatment with those who were randomly allocated to a non-optimal treatment based on the precision treatment rule.

Internet Transdiagnostic-CBT for Anxiety and Depression in Adolescents
This study represents the first research program to assess the efficacy of transdiagnostic cognitive behavior therapy (T-CBT) delivered via internet for anxiety and depression in adolescents. The primary aim of the study was to implement the program AMTE (Aprende a Manejar tus Emociones \[Learn to Manage Your Emotions\]), an internet delivered T-CBT protocol designed to target both anxiety and depression symptoms and disorders (major depression disorder, dysthymic disorder, panic disorder, agoraphobia, generalized anxiety disorder, and social anxiety disorder) in adolescents, and to establish its preliminary efficacy on anxiety and depressive symptomatology. A secondary objective is to demonstrate its potential effect regarding: (a) transdiagnostic measures associated with etiology of emotional disorders including negative affect, anxiety sensitivity, and emotional avoidance, and (b) positive factors including satisfaction with life and positive affect. It is expected that the T-CBT condition will be more effective than an active control condition (ACC) on the primary (anxiety and depression) and secondary (transdiagnostic and positive factors) outcome measures. The study is a randomized controlled trial with two arms (an experimental group and an active control condition). Assessment is contucted at pre-treatment, post-treatment, and at 3-, 6- and 12-month follow-up. For ethical reasons, participants in the ACC condition are offered the opportunity to receive the experimental condition (i.e., the iUP-A) following the completion of the post-treatment assessment.

PB-18 Probiotic for Mild to Moderate Depression
The goal of this clinical trial is to learn if Bifidobacterium PB-18 can treat mild to moderate depressive disorder in adults aged 18 to 65 years who are not taking antidepressants or other psychotropic medications during the study. It will also learn about the safety of Bifidobacterium PB-18 and explore its potential effects on the gut-brain axis. The main questions it aims to answer are: Does Bifidobacterium PB-18 increase the response rate at Week 8, defined as a reduction of at least 50% from baseline in the 17-item Hamilton Depression Rating Scale (HAMD-17)? What adverse events occur in participants receiving Bifidobacterium PB-18? How do gut microbiota, metabolite profiles, and related biological markers change after treatment with Bifidobacterium PB-18? Researchers will compare Bifidobacterium PB-18 with a placebo, a look-alike powder that does not contain PB-18, to see if Bifidobacterium PB-18 improves depressive symptoms. Participants will: Be randomly assigned to receive Bifidobacterium PB-18 or placebo in a 1:1 ratio Take the assigned study product once daily for 8 weeks Visit the study site at baseline, Week 4, and Week 8 for symptom and safety assessments Complete study questionnaires, including HAMD-17, HAMA, PSQI, and CBCT Provide blood and stool samples at baseline and Week 8 for exploratory biological analyses

Mindfulness Engaged Neurostimulation for Depression (MEND II)
Repetitive Transcranial Magnetic stimulation (rTMS) is an FDA-approved therapy for treatment resistant depression (TRD) that involves brief magnetic stimulation pulses on the dorsolateral prefrontal cortex (DLPFC) brain region. But studies of rTMS alone show remission rates of \~30%. Additionally, rTMS has not been shown to improve cognitive functioning that may be an independent factor predicting treatment success. This study will develop a novel multimodal treatment, which combines intermittent theta burst stimulation (iTBS) - a type of rTMS with digital mindfulness training to engage brain plasticity, enhance cognition and alleviate depression symptoms in individuals with TRD.

The STEP-MIED Trial: Digital Stepped-Care for Emotional Disorders
The goal of this clinical trial is to evaluate the effectiveness and cost-effectiveness of a digital mindfulness-based intervention in adults (aged 18-65) diagnosed with emotional disorders like depression or anxiety. The main questions it aims to answer are: * Does adding a digital mindfulness intervention to usual care help people recover from emotional disorders faster and more sustainably over two years? * Is this combined approach more cost-effective than usual care alone? Researchers will compare the group receiving the digital mindfulness intervention plus their usual treatment to the group receiving only their usual treatment to see if the intervention leads to better long-term recovery and represents good value for money. Participants in the intervention group will: * Attend eight weekly 2-hour online group mindfulness sessions. * Use a WeChat mini-program for 49 days of guided mindfulness exercises and daily tasks. * Patients who have not achieved reliable recovery after group retraining voluntarily participate in individual UP\&MIED counseling. * Complete regular questionnaires and interviews over two years to track their progress. All participants will continue to receive their usual medical care from their doctors throughout the study.
