Cognitive Fitness for Depression in Older Adults
Depression MildDepressive Disorder2 moreThis research is being done to determine if computerized administered cognitive fitness activities will improve thinking and depression in older depressed adults who are being treated with antidepressants. The investigators are also interested in whether participating in the treatment will result in changes to brain activity measured with magnetic resonance imaging (MRI).
Neuromodulation of Mind-Wandering in Depression
DepressionThe specific aim of this proposed study is to investigate the feasibility and therapeutic potential of LIFUP in changing negative cognition in depression. Specifically, the investigators will study if modulating DMN activity can change maladaptive mind-wandering. The investigators hypothesize that DOWN-modulation of the posterior cingulate cortex (PCC), a key DMN node, will decrease DMN resting state functional connectivity, perfusion, and activation during a cognitive-affective task (description below). The investigators also hypothesize that DOWN-modulation of the PCC will be associated with decreased mind-wandering and increased mindfulness. Finally, the investigators hypothesize that the opposite will be true for UP-modulation of the PCC.
Affect Treatment for Depression and Anxiety
DepressionAnxietyThe purpose of this study is to evaluate the efficacy and mediators of change in Positive Affect Treatment, a psychotherapy specifically aimed at enhancing reward sensitivity in individuals with low positive affect (a core feature of anhedonia) in the context of depression or anxiety. Target enrollment is 100 male and female participants with low positive affect and depression or anxiety and impaired functioning, between the ages of 18 and 65 years, who will be randomized to either Positive Affect Treatment or Negative Affect Treatment (designed to reduce threat sensitivity). Participants will complete laboratory tests, psychiatric assessments, and self-report questionnaires as part of the study. The total length of participation is around 5 months.
Cognitive Behavioral Therapy (REBT) Evaluation for Depression at Primary Care.
DepressionBackground: Rational Emotional Behavioral Therapy (REBT) applied by the Primary Health Care (PC) Social Worker reduces psychotropic drug use and overcrowding at medical appointments. Hypothesis: The REBT in people diagnosed with mild-moderate depression in the social work consultation of PC, improves the clinical control of this disorder, with lower consumption of health resources, better quality of life and user satisfaction, with respect to the usual clinical practice, in addition to being cost-effective. Goals: To compare the effectiveness, cost-effectiveness and cost-utility of REBT as an intervention tool with respect to the usual clinical practice in adults with a diagnosis of mild-moderate major depression in PC. Methodology: Randomized clinical trial with control group, in people diagnosed with major depression attached to the PC. This study is carried out in 9 primary care centers in Catalonia. Determinations: Participants are measured at the beginning of the study, end of the intervention and at 1 year of the beginning: Control of symptoms using PHQ-9; Health-related quality of life using the EQ-5D-5L scale; Self-perceived well-being, using the Ryff Psychological Well-Being Scale; Pharmacological prescription and withdrawal of anxiolytics, hypnotics and antidepressants; Frequency of PC consultations; Assignable costs through TIC-P; Functional social support perceived prior to the intervention using the Duke questionnaire; and user satisfaction with the treatment at the end of the intervention using CRES-4. The exposure variable is the assignment to the REBT psychosocial intervention group or the usual clinical practice control group. Statistical analysis: Description of the items of the measuring instruments used per month will calculate the cost by variation of quality-adjusted life year (QALY) and the increase of associated cost-effectiveness ratio contrasting the hypothesis that this is different to 22000 € by means of t-test. Expected results: REBT in people diagnosed with mild-moderate depression in the social work consultation of PC, will improve in the clinical control of this disorder, a lower consumption of health resources, improvement in the Quality of Life and in the user satisfaction. Therefore, REBT is effective, and cost-effective in managing people diagnosed with mild-moderate major depression. Applicability and Relevance: REBT will help people to acquire tools to deal with difficulties in daily life and provide economic savings in health care costs.
Testing a Lifestyle Physical Activity Intervention for Women With Depression in Alcohol Treatment...
Alcohol Use DisorderDepressionThe primary aim of this project is to test the efficacy of a technology-supported lifestyle physical activity (LPA) intervention for preventing relapse among women with depression engaged in alcohol treatment. Participants are randomized to either 1) LPA+Fitbit intervention or 2) Fitbit Only control condition. Follow-up assessments and EMA data will be collected.
Internet-Based Cognitive Behavioural Program for Managing Stress With IBD: An RCT
Inflammatory Bowel DiseasesAnxiety2 moreThe study will examine the efficacy of an internet-based cognitive behavioural therapy (iCBT) for Inflammatory Bowel Disease (IBD) intervention to reduce stress, anxiety, and depression in individuals with IBD and comorbid clinically elevated t anxiety and/or depressive symptoms. The investigators will conduct a two-arm RCT comparing participants receiving the iCBT intervention (intervention group) and those receiving Treatment As Usual (TAU).
To Improve Depressive Symptoms Using a Web-App
DepressionThis study is being done to answer a question on whether a Web App-based Lifestyle Physical Activity Promotion Program is effective in improving depressive symptom experience of midlife Korean American women (WPAPP-K).
The Effects of Videogames on Depression Symptoms and Brain Dynamics
Major Depressive DisorderThe purpose of the study is to evaluate the effects of a game-based digital-therapeutics (DTx) medical software device on the symptoms of depression in adults with confirmed major depressive disorder.
Dorsomedial Prefrontal Neuromodulation in Treatment-resistant Depression
Treatment-resistant DepressionMajor Depressive DisorderMajor depressive disorder (MDD) is a common and troublesome disorder, with high risk of physical and psychiatric comorbidity. At least one-third of patients could not achieve a response after several antidepressant trials, so-called treatment-refractory depression (TRD). The high-frequency repetitive transcranial magnetic stimulation (rTMS) or intermittent theta-burst stimulation (iTBS) at left-sided dorsolateral prefrontal cortex (DLPFC) have a response rate of 40-60%. Obviously, not all TRD patients achieve the remitted state after treatment with antidepressants or DLPFC-rTMS, which may result from the heterogeneity of MDD. More and more evidence, such as brain lesion studies, deep brain stimulation, open-labeled rTMS case series, and neuroimaging studies, suggests that dorsomedial prefrontal cortex (DMPFC) might play a more central role in the pathophysiology of major depression. The DMPFC demonstrated as a "dorsal nexus" phenomenon in depression, which means a unique brain region where cortical networks for affect regulation, default mode control and cognitive control coverage in depressed subjects but not in healthy persons. In addition, another meta-analysis of resting-state functional MRI (fMRI) demonstrated the abnormal functional connectivity from DMPFC. These abnormalities of networks were highly associated with several depressive symptoms such as anhedonia, emotional regulation, somatic markers, rumination, self-reflection, poor attention and poor decision-making. However, only a handful of studies investigated the brain stimulation targeting DMPFC and the further changes in brain functional connectivity. The clinical efficacy and the fMRI changes of prolonged intermittent theta-burst stimulation (piTBS) and 20Hz- rTMS targeting bilateral DMPFC were investigated, and the predictive value of baseline networks by fMRI for antidepressant responses was also assessed to find a reliable approach to gauge treatment response prospectively.
Light and Ion Maintenance In Treatment for Depression (LIMIT-D): Feasibility Study
Major Depressive DisorderRecurrent1 moreAntidepressants are widely used as first-line treatments for major depressive disorder (MDD). Clinical guidelines recommend 6-24 months of "maintenance" antidepressant treatment, after patients achieve symptom remission, to prevent relapse but many people stop antidepressants too soon relapse into another depressive episode. We will test non-medication treatments, negative ion therapy and light therapy, to see they can substitute for antidepressants to prevent relapse. This is a "feasibility" study to see if participants use study treatments properly, before doing a larger, definitive trial. In this 28-week study, 100 participants with recurrent MDD who are in remission with antidepressants will be treated with light therapy or negative ion therapy (with half of devices active and half inactive) while slowly discontinuing the antidepressant, and monitored for relapse.
