Filter by:The hypothesis was that a large fraction of individuals with common mental disorders were undetected in long-term sickness and that detection of the disorders by screening, a psychiatric diagnostic examination and feedback to the individuals, primary care, and rehabilitation officers improved return to work, improved quality of life and reduced psychological distress.
The purpose of this study is to investigate the usefulness of neuroscience-guided cognitive training combined with community-based supported employment for people with schizophrenia. The investigators will examine the effectiveness of moving our study of neuroplasticity-based restorative targeted cognitive training out of the laboratory and into the community setting; and the investigators will also investigate its utility in enhancing functional outcome in chronically mentally ill adults who are participating in supported employment.
The study evaluates the long-term efficacy and safety of SM-13496 in patients with bipolar I disorder.
This study will, in a sample of cocaine-dependent and healthy control subjects, administer corticorelin and compare dopamine release between groups. Dopamine release will be measured using PET neuroimaging with the radiotracer [11C]-(+)-PHNO.
Repetitive negative thinking (RNT) plays an important role in different psychiatric disorders, such as depressive and anxiety disorders, complicated grief, posttraumatic stress disorders, anorexia nervosa. RNT is seen as a vulnerability factor in the onset, duration, severity and relapse of those disorders. Although there is a lot of theoretical research, it is unknown if a group training protocol addressing RNT has an additional effect on Treatment as Usual (TAU) of patients with GAD or Depressive disorder. Our hypothesis is that a training intervention will show a significant effect on declined RNT activity (measured by PSWQ and LARRS), reduced identification with worrying/rumination (measured by CFQ-13 and a Visual Analogue Scale), and reduced scores on metacognitions questionnaire (MCV Dutch version of the MCQ), when compared to TAU (medication, psychotherapy or a combination of both treatments). Further we expect that this effect on RNT will not be temporary and the beneficial effects will remain present over a longer time (9 months). Our third hypothesis claims that reduced RNT will have an effect on Quality of Life, self-esteem and depressive and anxiety scores (measured respectively by WHO-QoL, Rosenberg Self Esteem Questionnaire, BDI-II and STAI; all of them in Dutch version). Fourth hypothesis concerns the effect of the training in the functioning on a neurobiological level. Here we expect that the beneficial effects of training on RNT will increase top-down prefrontal (dorsolateral) cortical control over an overactive bottom-up limbic system. To examine these neurobiological effects, we apply a multimodal approach where we combine resting state fMRI, structural MRI such as diffuse tensor imaging (DTI), anterior spin labelling (ASL). Further, in our department we developed an audio critique task where participants hear different kinds of critique amongst some of negative valence which will be especially problematic for ruminative patients reflecting difficulties and differences these top-down/bottom-up processes when compared to a healthy control group at baseline. Further, we hypothesize that only when coping with RNT is successful these neuronal processes will normalize. We do not expect changes in the waiting list group. To examine these clinical and neuronal effects, people suffering from GAD and/or depression will be allocated by randomisation to an active treatment condition (ATC) and a waiting list control group (WLC). All the participants will be patients treated by general practitioner, psychologist or psychiatrist. Training exists of 8 sessions in group (max 12 participants) on a weekly basis, except for the last session, which takes place after one month). During the training people will get information on RNT, they will be trained in re-allocation of their attention, will receive some basic ideas about becoming aware of dysfunctional thinking and learn coping strategies such as stimulus control and engaging in positive activity. Assessments will take place before and after treatment for the ATC. The WLC will be measured at the start of the WLC and 12 weeks later. Measurement takes place by means of questionnaires and fMRI. During the fMRI, people will undergo a resting state paradigm and some tasks triggering RNT. 3 and 9 months after the group treatment, participants will be evaluated again on RNT by means of questionnaires. Participants in WLC will receive group treatment from the moment the parallel active treatment condition is ended (e.g. after 12 weeks). This group will be evaluated immediately after training and at 3 and 9 months follow-up. At the end of the training, after the 8th session, two participants per run will be asked to cooperate in a qualitative in-depth interview. We are interested in linking results with the group training with some factors such as quantity of sessions, degree of active participation in between sessions. We are also interested in defining which interventions are perceived as most useful and if there is a link between disorder and the usefulness of some interventions.
The aim of this 2-stage, 3-site study is to investigate the effectiveness and safety of a combination of extended-release depot naltrexone plus extended-release bupropion as a potential pharmacotherapy for methamphetamine (MA) use disorder.
This study is a placebo-controlled 12 week trial of DCS augmentation of once-weekly CBT sessions in 60 schizophrenia subjects with antipsychotic-resistant delusions. In addition to testing efficacy, this trial will characterize DCS effects in terms of time course and persistence of response and will examine DCS effects on memory consolidation and cognitive flexibility as possible mediators of DCS enhancement of CBT for delusions.
The specific aim of the study is to evaluate the health benefits of a series of group workshops designed for workers with chronic physical health conditions. The facilitated workshops apply principles of pain and illness self-management to help workers deal with health-related challenges while at work. The workshops address issues of pain management, physical job demands, pacing of work, communication, problem solving, and coping. Half of the participants in the study will be randomly assigned to attend workshop sessions (10 hours total), and all study participants will be followed for one year. The primary hypothesis is that workers who participate in these workshops will show improvements in work engagement and reductions in work limitation in the subsequent 12 months.
The SMART Program at Nationwide Children's Hospital is an interdisciplinary social skills group that teaches children with autism spectrum disorders (ASD) ages 2-12 the fundamental social skills necessary to build and maintain relationships. The manualized curriculum addresses skills such as joint attention, eye contact, play, and peer engagement. Currently individual goals are set for each child who participates and this is documented in the daily treatment note. In order to research group outcomes, the investigators will use parent questionnaires (an addition to current clinical practices) to measure changes in behavior after each 12 week session for up to one year of treatment. The investigators hypothesize that maladaptive behaviors will decrease and adaptive behaviors will increase in children with ASD after participation in the SMART program.
This study aims to investigate reward learning across the mood disorder spectrum and to investigate the predictive validity of reward learning for subsequent symptom severity.
