Filter by:The aim of this study is to develop a scale to measure the severity of depression with psychotic symptoms (psychotic depression). Furthermore, we hope to detect potential biomarkers (substances in the blood) which can aid in the detection of psychotic depression. Main hypothesis: A clinically valid rating scale measuring the severity of psychotic depression can be developed.
Auditory verbal hallucinations (AVH) are a characterising symptom of schizophrenia. In the majority of patients, these AVH respond well to antipsychotic medication. Yet, a significant minority continues to experience frequent AVH despite optimal pharmacotherapy. The number of alternative treatment options for this medication resistant group is currently low and most of them focus on coping with the hallucinations. Transcranial magnetic stimulation (TMS), in contrast, is a non-invasive technique of influencing cortical excitability. This technique has the potential to actually decrease the frequency and severity of medication resistant hallucinations. Several previous studies have assessed efficacy of low frequency rTMS, with contradicting results. A previous large study by the investigators group could not demonstrate efficacy of low frequency rTMS. A new stimulation protocol using theta burst rTMS (TBS) could provide a more effective therapeutic option. Objective: The present study aims to examine the efficacy of TBS on the severity of AVH. Study design: The objectives are tested in a randomized double blind placebo-controlled trail. Study population: 60 patients with the diagnosis of schizophrenia, schizoaffective disorder, schizophreniform disorder or psychosis not otherwise specified with frequent auditory verbal hallucinations will be included. Intervention: The participant will receive either 10 TBS treatments or 10 placebo treatments consisting of 900 pulses each with a 30 minute interval on the left temporoparietal area, distributed over 5 treatment days. Stimulation will be at 80% of the motor threshold. Main study parameters/endpoints: the main study parameter is the change in the severity of the AVH. The secondary study parameter is the number and severity of adverse events.
The purpose of the present study is to examine whether cognitive behavior therapy will reduce depressive symptoms and increase self-esteem for patients with a first episode psychosis.
In order to meet an existing lack of empirical studies in the field of cognitive behavioral therapy supervision, the present randomized controlled trial is aimed at comparing two different types of supervision. This study compares computer-assisted live supervision and delayed video-based supervision regarding efficacy and acceptance among therapists, patients and supervisors. The efficacy of supervision is defined on different levels such as change of psychotherapeutic competence, nondisclosure, self-efficacy, self-awareness of the supervisee as well as therapeutic alliance, supervisory alliance and therapy outcome.
Learning includes the ability to generalize to new situations and respond to similar, yet not identical stimuli. In previous work, focused on stimulus generalization in healthy volunteers, tones that were negatively reinforced induce wider generalization curves than tones that were positively reinforced, and these in turn induce wider curves than neutral memory (Schechtman et al, 2010). The current study aimed to evaluate those patterns in different clinical disorders (including Schizophrenia, Bipolar disorder, MDD, Anxiety disorders (Panic and GAD) and PTSD, and healthy subjects that would be used as a control), with consideration whether those patterns are unique to any specific disorder or state. The generalization patterns evaluation would conduct twice though enable to compare the stability of those patterns during the course of the illness (i.e during remission compared to acute state). The basic paradigm based on conditioning of a tone (sound) with unpleasant noise, and extinction of that conditioning afterword. During the 60 minutes of evaluation, the capability to discriminate between the original tone and similar but not identical tones, and the tendency to categorize similar tones as identical to the original tone. A neutral tone without conditioning will be used as reference. The clinical diagnosis will conduct by a senior psychiatrist, and the state would be evaluated using standard questionnaires
The investigators will develop, deliver and evaluate a solar powered tablet-based individual and group focused HIV/STI prevention intervention with internally displaced women in Leogane, Haiti. Internally displaced women will be trained as community health workers to deliver the HIV/STI prevention intervention to other internally displaced women.
Persons with serious mental illness (SMI) are at increased risk of cardiovascular disease (CVD). The goals of this study are to test a treatment, Life Goals Collaborative Care to help promote health behavior change and improve mental health and physical health-related quality of life, as well as to get feedback from patients and providers on what is needed to help better coordinate the physical and mental health care of these patients.
Contingency management is efficacious for treating cocaine abuse, but contingency management interventions have rarely been applied to patients with severe and persistent mental health problems. This pilot project will estimate effect sizes of contingency management for reducing cocaine use in patients receiving psychiatric care at a large community based mental health program. In total, 30 cocaine abusing patients will be randomized to one of two 8-week treatment conditions: standard care or standard care with contingency management. Patients in both conditions will provide breath and urine samples for toxicology testing twice per week. In the contingency management condition, patients will receive the opportunity to win prizes for submitting cocaine negative urine samples. The investigators expect that patients receiving contingency management will evidence reductions in cocaine use and may show improvements in psychiatric symptoms and psychosocial functioning relative to patients in standard care. Effect size estimates obtained from this study will be used to guide larger scale and longer duration evaluations of contingency management for dually diagnosed patients.
MAN-BIOPSY pursues the concrete research question whether novel biological and psycho-physiological clusters or categories can be defined to improve treatment and minimize side effects in psychiatry, based on a synopsis of physiological, behavioural, genetic and endocrinological parameters. One major aspect of our research approach is its focuses on the identification of dysfunctions in fundamental information processing mechanisms and neurocomputational mechanisms, and is not restricted to symptom-oriented tasks. The main objectives of MAN-BIOPSY are therefore - to identify biological and psycho-physiological parameters for major depressive disorders and anxiety disorders, and - to identify predictive markers for treatment response and type/severity of side effects for these disorders.
The purpose of this study is to determine the effectiveness, with respect to symptoms and systemic inflammatory level, of mindfulness-based group treatment compared with normal treatment in patients diagnosed with minor to moderate mental disorders. The hypothesis is that mindfulness group-treatment 1) will be at least as effective as normal treatment in reducing psychiatric symptoms; 2) will increase quality of life compared with normal treatment; 3) will be costeffective compared with normal treatment; and 4) will reduce inflammation-related markers. The study will be conducted at primary care centers in Skåne, Sweden. We will assess the effect of mindfulness-based group treatment on psychiatric symptoms, quality of life, and health (as rated by the patients themselves) as well as inflammatory markers.
