Filter by:This two-armed randomized controlled trial aims to investigate the effectiveness of an emotion regulation intervention in individuals with and without depressive disorders. The study encompasses participants diagnosed with mild to moderate major depression or persistent depressive disorder and healthy controls without a current depressive disorder. Participants will be randomly assigned to either the intervention group, receiving a valence-specific emotion regulation intervention in daily life, or a monitoring-only control group. The valence-specific intervention supports the implementation of different emotion regulation strategies based on whether a person is experiencing mainly positive or negative emotions. In contrast, participants in the control group will solely monitor their positive and negative emotions and the strategies used to regulate them. Outcome measures include emotion regulation ability, self-efficacy, and strategy use, depressive symptoms, positive and negative affect, and emotion beliefs (controllability, usefulness). A second aim of the study is to compare beliefs about positive emotions and strategies to regulate them between individuals with and without current depressive disorders. Furthermore, the investigators aim to examine why individuals might choose unfavorable emotion regulation strategies even when feeling good. Therefore, another research question is, how emotion beliefs might explain emotion regulation strategy choice.
The purpose of this study is to investigate the responses of the brain region known as the subgenual anterior cingulate cortex (sgACC) during transcranial magnetic stimulation (TMS) in individuals with depression. Specifically, investigators aim to determine whether the sgACC is engaged when TMS is delivered to specific targets and if the engagement of sgACC changes throughout a full TMS treatment intervention. To achieve this goal, the investigators will employ a combination of TMS and Magnetic Resonance Imaging (MRI) procedures. Study participation will include completing various questionnaires, clinical assessments, receiving a full transcranial magnetic stimulation (TMS) treatment intervention (every weekday for 4-6 weeks), and undergoing MRI scans, both with and without concurrent TMS.
Depressive disorders are among the most common psychiatric disorders. However, this disorder is multifaceted, as are its etiological factors, and is not yet fully understood. Within the framework of the P4D study, 1000 patients with depression will be comprehensively examined. In addition to the recording of psychological factors by means of questionnaires and third-party assessments, imaging and electrophysiological procedures (functional and structural MRI, EEG) are used to assess brain structure and function. In addition, blood is drawn from the subjects to analyze these samples for various biological markers (e.g., genetics). Drug level measurements are also performed. The goal is to perform an in-depth characterization (phenotyping) of individuals with a depressive disorder. These findings could be used to individualize and improve therapy for depressive disorders.
This study aims to better adapt cognitive behavioral therapy for insomnia (CBTi) for people with comorbid depression by using objective sleep measures to tailor the behavioral interventions components of CBTi. Using ambulatory monitors, we also aim to investigate changes in brain activity and heart rate throughout the intervention. In this parallel-group randomized clinical trial, participants undergo one week of baseline ambulatory monitoring after which they are randomly assigned to one of two intervention arms: 1) digitally delivered CBTi (eCBTi) based on standard subjective sleep measures (sleep diary), or 2) eCBTi based on objective sleep measures (EEG headband). The intervention spans over 5-weeks, followed by a week of ambulatory monitoring and follow-up measures one week and one month after the end of the intervention. The study also includes a post-intervention interview to gather feedback on participant experiences. The overall protocol includes online questionnaires and structured clinical interviews assessing sleep, insomnia, and mental health, as well as treatment-related measures before, during, and after the intervention. It is anticipated that eCBTi using objective sleep measures will lead to better treatment acceptability, satisfaction, and effectiveness, including greater improvements in symptoms of insomnia and depression. It is also anticipated that sleep EEG and heart rate profiles will improve along the course of eCBTi.
The goal of this multiple baseline case series study is to test Imagery Rescripting in depression. The main question[s] it aims to answer are: - does Imagery Rescripting lead to a reduction of depression and of believability of negative beliefs held by the participants? - does Imagery Rescripting also leads to reductions in worrying and brooding? - Participants will wait for 6-10 weeks (to assess time effects without treatment), followed by 5 weekly preparation sessions, 8-12 weekly Imagery Rescripting sessions, and 5 weeks post-treatment. - Participants will rate the believability of 3-5 core dysfunctional beliefs related to their depression as well as 2 items assessing depression severity on a weekly basis. In addition, they will fill out more extensive questionnaires on depression, worry and brooding before each phase, as well as at 5 weeks post-treatment, and 6 and 12 months follow-up.
Depression is a common disorder that often takes a recurrent or chronic course. Recent research has indicated that such courses are associated with significant changes in brain functioning including changes in strength of functional connectivity between regions of the default mode network, a large-scale brain network involved in spontaneous thinking and rumination, and the ability to suppress this network. Training in mindfulness has been found to be an effective treatment for patients with recurrent and chronic courses of depression and there is evidence for beneficial effects on brain structure and functioning. However, it remains unclear whether and in how far the training may serve to reverse brain changes in recurrent and chronic courses of depression. The aim of this research is to test the effects of sustained training in mindfulness meditation on default mode network connectivity and suppression in patients suffering from recurrent or chronic depression. The investigators will invite currently depressed patients with a recurrent or chronic course of the disorder (N = 36) to take part in a 6-month mindfulness intervention and investigate changes in default-mode network connectivity and suppression over repeated assessments. Building on our previous research, the intervention will use a blended format that combines an online app offering psychoeducational materials and meditation guidance with brief individual therapy sessions delivered via videoconference. Eligible participants will be asked to complete questionnaires and take part in brain scans before the start of the treatment, 3 months after the start of the treatment and after the end of treatment.
The study evaluates whether Intensive psychotherapy show superior effect on chronic depression over TAU
The study team will conduct a Multisite Randomized Controlled Trial to evaluate the advantages and disadvantages of two approaches for quitting smoking among people with serious mental illness (SMI). The study will compare a novel app tailored to people with SMI, Quit on the Go, to a standard of care smoking cessation intervention. We will test the effectiveness of the Quit on the Go app, an intervention that has demonstrated feasibility and acceptability in the target population, as a tool for smoking cessation in people with SMI. Participants with SMI will be recruited across 3 sites (Duke University, Univ. at Buffalo, and Wake Forest University).
The purpose of this study is to compare the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) conducted over 16 weeks (acute and continuation treatment) with Behavioral Activation (BA; same dose and duration) in persistently depressed treatment-resistant inpatients regarding efficacy, moderators and mediators of change.
