The goal of this exploratory, mixed-method design study is to gather qualitative and quantitative data obtained through interviews and questionnaires with veterans who are currently enrolled at the VA for healthcare. The main question this study aims to answer is: How do veterans aged 65+ who are enrolled for care at the VA understand ketamine assisted psychotherapy for depression and for end-of-life distress? Using a story-completion approach, participants will be provided with a brief story starter involving a fictitious character and scenario and asking them to complete the story. Few contextual details will be offered about the character. In responding to ambiguous cues, participants are thought to project their conscious and subconscious perceptions about the phenomenon in question onto the story, a useful method for exploring stigmatized topics. The purpose of this exercise is to ascertain the participants attitudes and perceptions regarding ketamine assisted psychotherapy.

This study will deploy a scalable secondary prevention program that leverages existing foster youth transition services to improve mental health functioning and service use before and after exiting foster care. Our short-term objective is to remotely test a group intervention called Stronger Youth Networks and Coping (SYNC) that targets cognitive schemas influencing stress responses, including mental health help-seeking and service engagement, among foster youth with behavioral health risk. SYNC aims to increase youth capacity to appraise stress and regulate emotional responses, to flexibly select adaptive coping strategies, and to promote informal and formal help-seeking as an effective coping strategy. The proposed aims will establish whether the 10-module program engages the targeted proximal mechanisms with a signal of efficacy on clinically-relevant outcomes, and whether a fully-powered randomized control trial (RCT) of SYNC is feasible in the intended service context. Our first aim is to refine our SYNC curriculum and training materials, prior to testing SYNC in a remote single-arm trial with two cohorts of 8-10 Oregon foster youth aged 16-20 (N=26). Our second aim is to conduct a remote two-arm individually-randomized group treatment trial with Oregon foster youth aged 16-20 with indicated behavioral health risk (N=80) to examine: (a) intervention group change on proximal mechanisms of coping self-efficacy and help-seeking attitudes, compared to services-as-usual at post-intervention and 6-month follow-up: and (b) association between the mechanisms and targeted outcomes, including emotional regulation, coping behaviors, mental health service use, and symptoms of depression, anxiety, and PTSD. Our third aim is to refine and standardize the intervention and research protocol for an effectiveness trial, including confirming transferability with national stakeholders.

Questions remain regarding MBC's unique added value compared to usual care. Thus, the goal of this clinical trial is to investigate the implementation outcome, effectiveness, and mechanisms of change of measurement-based care in adult behavioral health. This study implemented MBC in adult ambulatory behavioral health and will test outcomes using a pragmatic randomized control trial within the RE-AIM (Reach, Efficacy, Adoption, Implementation, and Maintenance) framework. Researchers will compare three groups: 1) the Measurement-based care group, 2) the treatment-as-usual group, and 3) the waitlist control group. Participants will participate in weekly individual psychotherapy sessions for 12 sessions in total.

Behavioral Exposure for Interoceptive Tolerance (BE-FIT) is a mechanism-informed behavioral intervention to target exercise anxiety. The three primary components of BE-FIT include: (1) exposure to feared bodily sensations and exercise; (2) prevention of safety behavior use before/during/after exercise, and (3) use of a wrist-worn activity monitor for physical activity (PA) feedback and activity goal setting. Evidence from the investigators' Stage I trial indicated that BE-FIT is feasible, acceptable, and safe and produced reductions in exercise anxiety and increased exercise outcomes (short-term moderate-to-vigorous intensity physical activity and steps/day). The investigators' present aim is to conduct a Stage II randomized-controlled trial to further evaluate the efficacy of BE-FIT in decreasing exercise anxiety in cardiac rehabilitation (CR) patients and examine whether changes in this target yield successive changes in exercise adherence outcomes.

Using a hybrid type 1 effectiveness-implementation approach, this study aims to evaluate the impact of a novel stepped care model ("PCT+2HOPE") versus treatment as usual (TAU) on increasing retention in community-based medication for opioid use disorder (MOUD) treatment among women who have experienced intimate partner violence (W-IPV). PCT+2HOPE includes Present-Centered Therapy (PCT+) with stepped care as indicated by moderate, severe, or extreme PTSD-related impairment in psychosocial functioning to Helping to Overcome PTSD through Empowerment (HOPE), two evidence-based behavioral interventions adapted for women with opioid use disorder (OUD). We will examine the effectiveness of PCT+2HOPE vs. TAU on the primary outcome (i.e., retention in MOUD treatment) and secondary outcomes related to trauma (i.e., PTSD-related impairment in psychosocial functioning and depression), substance use (i.e. OUD symptom severity, extra-medical opioid use [i.e., use of prescription opioids without a doctor's prescription; in greater amounts, more often, longer than prescribed, or for a reason other than a doctor said they should be used], and recovery), and empowerment. We will explore the extent to which the effectiveness of PCT+2HOPE vs. treatment as usual differs based on access to basic needs. We will also conduct an implementation-focused process evaluation.

Study Description: This study examines relations between neurocognitive and clinical features of pediatric anxiety disorders. The study uses neuro-cognitive tasks, functional magnetic resonance imaging (fMRI), as well as magneto- and electro-encephalography (M/EEG). Patients will be studied over one year, before and after receiving either one of two standard-of-care treatments: cognitive behavioral therapy (CBT) or fluoxetine, a serotonin reuptake inhibitor (SSRI). Healthy comparisons will be studied at comparable time points. Primary Objectives: To compare healthy youth and symptomatic, medication-free pediatric patients studied prior to receipt of treatment. The study seeks to detect relations between clinical features of anxiety disorders at baseline and a wide range of neurocognitive features associated with attention, memory, and response to motivational stimuli. Secondary Objectives: 1. To document relations between baseline neurocognitive features and response to Cognitive Behavioral Therapy (CBT) or fluoxetine, as defined by the Pediatric Anxiety Rating Scale (PARS) and Clinical Global Improvement (CGI) Scale. 2. To document relations between post-treatment changes in neurocognitive features and anxiety symptoms on the PARS following treatment with Cognitive Behavioral Therapy (CBT) or fluoxetine. 3. To document relations among broad arrays of clinical, cognitive, and neural measures Primary Endpoints: Indices of percent-signal change in hypothesized brain regions, comprising amygdala, striatum, and prefrontal cortex (PFC) for each fMRI and MEG paradigm. Secondary Endpoints: 1. Treatment-response as defined by a continuous measure, the Pediatric Anxiety Rating Scale score (PARS), and a categorial measure, the Clinical Global Improvement (CGI) score. 2. Levels of symptoms and behaviors evoked by tasks that engage attention, memory, and elicit responses to motivational stimuli.

Bipolar disorder often runs in families, but early symptoms in youth can go unrecognized for years. This project evaluates a structured, family-centered approach to informed screening for youth ages 7-21 who have a biological parent with bipolar disorder. The main questions addressed by this project are: Whether a co-designed video decision aid improves caregiver understanding of bipolar disorder genetic risk and supports informed decisions about youth screening. Whether remote mental health screening tools are feasible and acceptable for youth with familial risk for bipolar disorder. Whether screening results can be used to identify early risk patterns and inform tailored follow-up recommendations. Participants may be involved in one or more study activities, including co-design of educational decision-aid content, feedback on decision-aid prototypes, beta testing of the decision aid, and remote youth mental health screening. The study does not assign treatment and does not change existing clinical care or clinic routines.
