Filter by:This study is a 28-day randomized controlled trial (RCT). Residents were randomly assigned to an intervention group or a waiting group according to the order in which they were successfully contacted by the staff, and each user was asked to engage in a total of 28 days of dialog intervention with the Douyin companion bot and complete three psychological questionnaires (on Days 1, 14, and 28); however, the intervention group began to receive the dialog intervention after completing the first questionnaire, and the waiting group began to receive the dialog intervention after completing the third questionnaire. During the first four weeks, the waiting group was treated as a blank control. The two groups of subjects completed the three questionnaires at exactly the same point in time. Each user's depression, anxiety, and positive and negative emotions were measured using the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder Scale (GAD-7) and the Positive and Negative Affect Schedule (PANAS), respectively.
Although treatments for depression are effective for many people, not everyone responds to treatment. This lack of treatment response could be due, in part, to the presence of multiple underlying causes of people's depression. This study aims to identify subtypes of depression, based on two factors: how successful people perceive themselves to be at regulating their affect in everyday life; and how much activity in the parasympathetic nervous system increases during moments when people try to regulate. The study involves ambulatory assessment of affect, regulation strategies, and physiological activity in everyday life, in a sample of young adults with remitted major depressive disorder and healthy volunteers. We will study regulation responses in the lab to further determine how subtypes differ in neural, physiological, and behavioral responses. Finally, participants will be randomly assigned to a remote, self-administered biofeedback intervention (vs. control intervention) designed to increase parasympathetic activity and physiological regulation success. While engaging in biofeedback at home for 10 days, participants will simultaneously repeat the ambulatory assessments. This design will allow us to determine the proximal impact of biofeedback on indices of regulation success in everyday life, and whether biofeedback has differential impact on regulation success for different subtypes.
Major depressive disorder (MDD) is a common severe psychiatric disease with enormous socioeconomic costs for the patient and society alike. Current pharmacological treatments are ineffective in a substantial fraction of patients and are accompanied by unwanted side effects. Using a novel non-invasive brain stimulation method to specifically target and modulate dysfunctional brain oscillations with high spatial and temporal precision this study will investigate the efficacy of EEG-triggered transcranial magnetic stimulation to alleviate de-pressive symptomatology in patients with MDD in a double-blind randomized controlled pilot clinical trial.
The purpose of this study is to determine if treatment with a single dose of RE104 for Injection reduces depressive symptoms in participants with moderate-to-severe postpartum depression (PPD) as compared to active-placebo.
This proposal seeks to conduct a pragmatic single arm, open label pilot implementation to validate our individualized functional Magnetic Resonance Imaging (fMRI) connectome-guided localization approach for accelerated TMS among Asian patients with depression. Participants will be patients with Major Depressive Disorder not responding to standard treatment, with no exclusions to fMRI or transcranial magnetic stimulation (TMS) (essentially metal implants in the head) and willing to participate in the pilot. All participants will undergo MRI scans before and after the accelerated TMS treatment. The multi-session hierarchical Bayesian model (MS-HBM) approach will be used to estimate individualized connectome-guided target locations. Patients will undergo accelerated TMS applied to individualized connectome-guided target locations (based on the MS-HBM approach). Patients will undergo 10 sessions (each session lasting 10 min) spread out over 10 hours each day for 5 consecutive working days. All clinical outcome data will be collected for each patient by a pre-defined questionnaire at four time points: at baseline, post-treatment, 1 month and 3 months during follow-up. The clinical outcome data will be analyzed using linear regression or repeated analysis of variance (ANOVA) after adjusting for baseline clinical characteristics and socio-demographics. Trajectories of the clinical outcome data at baseline, post-treatment and all follow-up time points will be plotted and compared with time series statistical analysis models with the other clinical and socio-demographic characteristics included as confounders.
The purpose of this study is to see if one or two doses of psilocybin is more effective in relieving depressive symptoms in patients with treatment-resistant depression (TRD). Researchers also want to know if a second dose of psilocybin is safe and well-tolerated. This study will see if psilocybin is effective, safe, and well-tolerated by tracking changes in depressive symptoms, suicidality, and side effects. This study will also see if a second dose of psilocybin has an effect on quality of life, functioning, cognition (thinking, reasoning, remembering), and how long depressive symptoms improve (or worsen) after psilocybin is administered.
The study is a Phase 2, double-blind, randomized, placebo-controlled study in Major Depressive Disorder (MDD) participants with an inadequate response to standard antidepressants The objective of the study is to assess CLE-100 (oral esketamine) for the treatment of MDD in participants currently treated with an oral antidepressant medication and who have an inadequate response to at least 2 antidepressants.
Objectives: To identify in patients with major depression different peripheral markers of neuroinflammation in relation to affective symptoms (anxiety, depression, irritability), fatigue and cognitive symptoms; and its relationship with the response to antidepressant treatment with selective serotonin reuptake inhibitors (SSRIs). Methodology: This is a prospective observational cohort study in patients with major depression naturally subjected to treatment with SSRIs. For this, 30 patients with major depression attended in the Outpatient Psychiatry Consultations will be selected. All of them will be evaluated at baseline and after 3 months of treatment, collecting demographic and clinical variables, Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) psychiatric diagnoses, psychopathological scales and immunological and biochemical variables. The correlation between immunological markers and affective and cognitive symptoms at baseline, as well as their variation with treatment, will be analyzed. A group of 20 healthy subjects will be used as a control group. Subsequently, a bivariate comparative analysis will be carried out, where the statistically significant or marginally significant variables associated with psychopathological variables will be used to build a multivariate binary logistic regression model.
The goal of this study is to evaluate the effectiveness of an behavioral activation intervention to increase meaningful activity and community participation for people with serious mental illness. The overall objective of this study is to increase engagement in meaningful activities and community participation. The objectives of the project are as follows: 1. To determine if the intervention leads to increases the frequency and variety of activities. 2. To determine if the intervention leads to increases in community mobility. 3. To determine which demographic and environmental factors and mechanisms of action impact the effectiveness of the intervention. 4. To determine if the the intervention leads to an improvement in overall well-being (e.g., improved quality of life). Participants will be asked to attend a 2-hour weekly online session for 10 weeks and then a 1-hour online monthly session for a 3 month maintenance period. For data collection, participants will also be asked to: 1. Complete three, approximately 1-hour interviews at baseline, after the 10 week intervention, and again at the end of the maintenance period; 2. Carry a mobile phone with a global positioning system app to track their movements outside their home for 2 weeks at a time, at three separate times (e.g., baseline, after the intervention, and at the end of the maintenance period); and 3. Complete a 15 minute weekly interviews for 26 weeks about their daily activities and participation. The study will enroll 52 participants split into 4 cohorts of 13. The study will use a multiple baseline design and, as such, all participants will receive the intervention and there is no control group.
The purpose of this research study is to develop and test an intervention designed to improve mood and reduce symptoms of depression.
