Filter by:Depression is one of the most prevalent mental disorders to afflict adults. It seriously impacts role functioning and often takes a recurrent or chronic course. Because most adults who suffer from depression never receive treatment, there is a critical need to develop interventions that can be easily implemented and widely disseminated. Interventions that reduce the performance-impairing symptoms of subclinical depression and prevent the onset of major depression can improve employee well-being, while reducing healthcare costs and improving productivity. This project produced a mobile-web program to activate cognitive behavioral skills in workers with subthreshold depression, reduce depression symptoms, improve functioning in the workplace, and potentially reduce the risk for escalation to full-syndrome depression.
SimCoach, a computer program featuring a virtual human that speaks and gestures in a videogame-like interface, is designed to encourage servicemembers, especially those with signs or symptoms of post-traumatic stress disorder (PTSD) or depression, to seek help to improve their psychological health. The assessment included a formative component assessing SimCoach's design, development, and implementation approaches, as well as a summative component assessing outcomes among participants in a user experience survey and a randomized controlled trial (RCT).
Few studies targeting obesity in serious mental illness have reported clinically significant risk reduction, and non have been replicated in community settings or demonstrated sustained outcomes after intervention withdrawal. The researchers sought to replicate positive health outcomes demonstrated in a previous randomized effectiveness study of the In SHAPE program across urban community mental health organizations serving an ethnically diverse population.
The purpose of the study is to describe the association/correlation between change in patient-reported cognitive symptoms and work productivity in gainfully employed patients receiving vortioxetine for a Major Depressive Episode (MDE).
It can be difficult to achieve remission in individuals with late-life depression (LLD) and they often require aggressive treatment. This challenge is in part due to age-related vascular changes that are common in LLD. Successful antidepressant treatment involve changes across affective, cognitive, and default mode networks. We hypothesize that in LLD, vascular disease adversely affects response to antidepressants by disrupting connectivity of these networks. The primary goal of this project is to characterize how focal vascular damage affects regional connectivity and response to antidepressants. Based on past work and pilot data, we a priori focus on the cingulum bundle and uncinate fasciculus. These key fiber bundles connect frontal, temporal, and cingulate regions involved in cognition and affective responses. Our central hypothesis is that ischemic damage to the cingulum bundle and uncinate fasciculus contributes to structural and functional connectivity deficits of those tracts. This results in a disconnection effect that alters the function of connected regions. In turn, this increases the risk of a poor response to antidepressants. Our approach is to enroll up to 130 adults over age 60 years with a diagnosis of Major Depressive Disorder. Subjects will complete clinical evaluation, cognitive testing, and MRI/functional MRI (fMRI) sessions, including an fMRI emotional oddball task that includes attentional and affective components. Participants will be stratified by cerebral lesion severity and randomized in a 2:1 ratio to a double-blinded 8-week trial of escitalopram or matching placebo. Those who do not remit will transition to an 8-week trial of open-label bupropion, an antidepressant with a different mechanism of action. This will allow us to determine if different and distinct circuit deficits affect response to antidepressants with different mechanisms of action while also accounting for the placebo response.
The purpose of this randomized controlled study is to evaluate acceptability and feasibility, and to gather preliminary data about efficacy, of "iDOVE," a brief emergency department introductory session + longitudinal automated text-message depression prevention program for high-risk teens.
The purpose of this study is to test the effects of a computerized approach/avoidance training (AAT) procedure on behavioral, affective, and brain mechanisms that are important for reward sensitivity and well-being in individuals diagnosed with major depression. The training procedure is designed to modify automatic approach responses for positive social stimuli. The primary aim is to determine the effects of approach/avoidance training on the functioning of brain systems during reward processing in individuals diagnosed with major depression. A secondary aim will determine whether brain activation patterns following approach/avoidance training predict subsequent affective and behavioral responses during reward processing. An exploratory aim will test whether completing the approach/avoidance training procedure in combination with a brief computer-delivered behavioral activation program for depression will produce larger changes in depression symptoms, positive emotions, and social relationship functioning from pre- to post-intervention compared to the control training procedure.
The proposed project aims to test the efficacy and neural correlates of a behavioral treatment program comprised of positive activity interventions in a sample of individuals seeking treatment for anxiety or depression. Participants will be randomly assigned to an immediate or delayed treatment condition, and will be compared on measures of positive and negative emotions, brain responses to reward and punishment/loss, subjective well-being, and symptoms at baseline and post-treatment.
The purpose of this study is to evaluate the feasibility of developing a microbiome probe of depression and to evaluate the microbiome change in a preliminary analysis of treatment response (n=20) vs. non response (n=20) to the antidepressant citalopram. This study is a 12 week open trial that will enroll approximately 80 participants (anticipated 40 study completers with paired biomarker data) with an episode of major depression, Bipolar I or Bipolar II and 40 age- and sex-matched healthy controls.
According to the World Health Organisation, depression and problem drinking are among the leading causes of disability worldwide. Most patients who present with problem drinking and/or depression have poor quality of life and pose a great economic burden to society due to their higher use of health services. We seek to develop a new, enhanced, efficient, innovative and cost effective treatment strategy aimed at reducing the burden that these two mental conditions impose on sufferers, their families as well as the community and health systems. In a recent pilot study of supportive text messages in Ireland conducted by the Principal Applicant and a team of researchers for patients with problem drinking and co-occurring depression, we established that patients who received twice daily supportive text messages for three months had significantly less depressive symptoms than those who did not receive such messages. There was also a trend that patients who received the supportive text messages were more likely to have higher alcohol free days than those who did not receive any supportive text messages.Our study was limited by the small number of participants and it did not examine the impact of the text messages on health services utilization. Our study did not also examine the effects of supportive text messages on those with only depression or only problem drinking. The proposed study seeks to extend the knowledge gained from the pilot study in Ireland by examining the impact of supportive text messages in the individual disorders
