Thought-Action-Fusion (TAF) is a cognitive bias that posits (1) having unwanted thoughts is morally equivalent to acting upon the thoughts (TAF-Moral; e.g., "Thinking about harming a child is as immoral as actually harming a child") and (2) having unwanted thoughts will increase the likelihood of t1 expand

Thought-Action-Fusion (TAF) is a cognitive bias that posits (1) having unwanted thoughts is morally equivalent to acting upon the thoughts (TAF-Moral; e.g., "Thinking about harming a child is as immoral as actually harming a child") and (2) having unwanted thoughts will increase the likelihood of the thoughts happening in real life (TAF-Likelihood; e.g., "My mother will get into a car accident, because I thought about it"). Given its central role in the development and maintenance of OCD, TAF has emerged as a potential treatment target for obsessive-compulsive disorder (OCD). Previous research has demonstrated that TAF is indeed a malleable construct. This study aims to examine the effects of a multi-session, personalized cognitive bias modification (CBM) for thought-action-fusion (TAF) on improving obsessive-compulsive (OC) symptoms in a college sample.

The goal of this clinical trial is to conduct a randomized controlled trial to enhance the capacity of pediatric primary care providers to assist their patients who struggle with anxiety. The study aims to refine and assess the feasibility of the Anxiety Action Plan (AxAP), a brief intervention to reduce pediatric anxiety, delivered by primary care providers (PCPs) in community pediatric primary care clinics. The goal of the AxAP is to enhance the capacity of PCPs to identify and intervene with anxious youth, which will enhance access to care in general and especially in locations with few mental health specialists. PCPs participating in this study will attend a training, administer the intervention to enrolled youth assigned to the MAPP condition, participate in coaching sessions, and fill out study questionnaires. Families participating in this study will complete evaluations with the study team, receive the intervention from their PCP (if assigned to the MAPP condition), and fill out study questionnaires. Researchers will compare the MAPP intervention to Enhanced Usual Care (EUC; consisting of videos, handouts, and other resources for anxiety reduction) to see the differences, if any, in child outcomes.

Although there are an increasing number of mental health treatment adaptations for older adults, there are still a number of factors to consider when making these adaptations. Cognitive decline is one such factor that places significant burden on older adults and can interfere with traditional mental health therapies. Engage is a behavioral treatment approach that has shown to be effective in treating late life depression. The investigators are testing the feasibility of Engage as a treatment method for late life depression in older adults with cognitive decline. The objective is to corroborate Engage as an alternative late life depression treatment method for a sub-population of older adults with cognitive decline. Cognitive decline poses a unique mental health treatment barrier that is often over looked in younger populations. With a relatively higher prevalence of cognitive decline in older adulthood, it is imperative that a feasible mental health treatment program that can be effective in the presence of cognitive decline.

Deficits in motivation and pleasure are common in depression, and thought to be caused by alterations in the ways in which the brain anticipates, evaluates, and adaptively uses reward-related information. However, reward processing is a complex, multi-circuit phenomenon, and the precise neural mechanisms that contribute to the absence or reduction of pleasure and motivation are not well understood. Variation in the clinical presentation of depression has long been a rule rather than an exception, including individual variation in symptoms, severity, and treatment response. This heterogeneity complicates understanding of depression and thwarts progress toward disease classification and treatment planning. Discovery of depression-specific biomarkers that account for neurobiological variation that presumably underlies distinct clinical manifestations is critical to this larger effort.

Title: ERG as a potential biomarker of SSRI-responsive PTSD: A pilot study Posttraumatic stress disorder (PTSD) affects many individuals who experience a traumatic event. Previous studies suggest that there is a connection between the brain and the retina, and that the electroretinogram (ERG) may be a valuable biomarker to tell us more about signals in the brain that are related to mental health disorders like PTSD. The goal of this observational study is to examine the ERG waveform in veterans with PTSD before and after a single dose of the selective serotonin reuptake inhibitor (SSRI), sertraline. Sertraline is one of two FDA-approved medications for the treatment of PTSD. The main questions this pilot study aims to answer are: 1. How does sertraline, an SSRI, influence the ERG waveform in veterans with PTSD? 2. Is there a significant correlation between baseline ERG signals and the change in ERG following SSRI treatment? Participants will be asked to: - Undergo ERG recordings before and after a single dose of sertraline. - Provide relevant clinical information related to PTSD symptoms and treatment history. Following the initial study visits, participants will enter an optional open label phase of the study in which qualifying participants who initiate antidepressant treatment through routine clinical care will be invited back for a follow-up ERG recording.

Little is known about whether and how brief mindfulness therapies yield clinically beneficial effects. This gap exists despite the rapid growth of smartphone mindfulness applications and presence of mental health treatment gap. Specifically, no prior brief, smartphone mindfulness ecological momentary intervention (MEMI) has targeted generalized anxiety disorder (GAD). Moreover, although theories propose that mindfulness intervention can boost attentional control (AC), executive functioning (EF), perspective-taking, and social cognition skills they have largely gone untested. Thus, this randomized controlled trial (RCT) aims to address these gaps by assessing the efficacy of a 14-day smartphone mindfulness EMI (vs. placebo). Participants with GAD will be randomly assigned to either MEMI or self-monitoring placebo (SMP). Those in treatment will exercise multiple core mindfulness strategies (open monitoring, acceptance, attending to small moments, slowed rhythmic diaphragmatic breathing). Also, those in MEMI will be reminded before bedtime that mindfulness is a lifelong practice. Comparatively, participants assigned to SMP will only be prompted to practice self-monitoring. They will notice their thoughts, rate any distress associated with them, and will not be taught any mindfulness strategies. All prompts will occur 5 times a day, for 14 consecutive days. They will complete self-reports and neuropsychological assessments at pre-, post-, and 1-month follow-up. Multilevel modeling analyses will determine if treatment (vs. self-monitoring placebo (SMP)) produces substantially larger reductions in trait worry and negative perseverative cognitions as well as steeper increases in AC and EF (inhibition, set-shifting, working memory updating). In addition, the investigators hypothesized that MEMI (vs. SMP) would lead to greater increases in performance-based and self-reported trait mindfulness, empathy, and perspective taking. Findings will advance understanding of the efficacy of unguided, technology-assisted, brief mindfulness in a clinical sample.

Background: Nicotine dependence leads to about 480,000 deaths every year in the United States. People with major depressive disorder (MDD) are twice as likely to use nicotine compared to the general population. They have greater withdrawal symptoms and are more likely to relapse after quitting compared with smokers without MDD. More research is needed on how nicotine affects brain function in those with MDD. Objective: To understand how nicotine affects symptoms of depression and related brain function. Eligibility: People aged 18 to 60 years, at the time of consent, with and without MDD who do not smoke cigarettes or use other nicotine products. Design: Participants will have 2 or 3 study visits over 1 year. Participants will have 2 MRI scans no less than 4 days apart. Each scan visit will last 5 to 7 hours. At each scan, they will have urine and breath tests to screen for recent use of alcohol, nicotine, and illegal drugs. Before each scan, they will take 1 of 2 medications: nicotine or placebo. Participants will receive each medication once. They will not know which medication they are receiving at each scan. For each MRI scan, they will lie on a table that slides into a cylinder. Sometimes they will be asked to lie still. Sometimes they will complete tasks on a computer. Tasks may include identifying colors or playing games to win money. Each scan will take about 2 hours. Participants will answer questions about their thoughts, feelings, and behaviors before and after each scan. They will have a blood test after each scan.
