Filter by:Five collaborating sites in France will study the broad spectrum of schizophrenia in children and adolescents. Patients will be studied with diagnostic interviews, developmental histories, dimensional clinical ratings, comprehensive cognitive assessments, neuroimaging and DNA (copy number variant) analyses (in families and patients who agree), and follow-up of course of illness, cognitive status and treatment response to specific antipsychotic drugs. The goal of the study is to test a prior hypothesis about clinical subgroups in this population and to test whether these subgroups predict antipsychotic medication response.
Single-blind, randomized controlled trial of normobaric oxygen therapy among individuals with first-episode psychosis: Effects on symptomatology and cognition.
The regions which are assumed to underlie the pathophysiology of schizophrenia, namely hypoactivity at the prefrontal level and pathological hyperactivity of the associative regions of the language located in the left temporoparietal region. To assess the efficacy of tDCS on auditory hallucinations, the investigators performs an randomized double blind versus placebo trial. In each arms patients will receive two tDCS sessions a day during two weeks.
The present study is a confirmatory efficacy trial of Family Focused Therapy for youth at clinical high risk for psychosis (FFT-CHR). This trial is sponsored by seven mature CHR clinical research programs from the North American Prodrome Longitudinal Study (NAPLS). The young clinical high risk sample (N = 220 youth ages 13-25) is to be followed at 6-month intervals for 18 months.
The aim of this study is to identify specifics of pre-ECT assessments and ECT application in European psychiatric services. We will engage European centres that provide ECT for psychiatric patients and for psychiatric indications. It could bring better insights on current standards and possibly give some further improvements in the field of European ECT practices.
Recovery-oriented care is an imperative for the VA, particularly in mental health programming for Veterans with serious mental illness (SMI). Collaborative decision-making (CDM) is a recovery-oriented approach to treatment decision-making that assigns equal participation and obligation to patients and providers across all aspects of decision-making, thereby empowering patients and facilitating better decision-making based on patient values and preferences. CDM is associated with several important outcomes including improved treatment engagement, treatment satisfaction, and social functioning. However, current levels of CDM among Veterans with SMI are low, and there is not yet an evidence-based method to improve CDM. Improving Veteran skill sets associated with engaging in CDM is a potential intervention strategy. Collaborative Decision Skills Training (CDST) is a promising new intervention that was previously developed by the applicant for use in adult civilians with SMI and found to improve relevant skills and improve sense of personal recovery. The proposed study has two primary stages. First, a small, one-armed, open label trial will establish CDST's feasibility will evaluate CDST among 12 Veterans with SMI receiving services at the VA San Diego Psychosocial Rehabilitation and Recovery Center (PRRC) and identify and complete any needed adaptations to CDST. Stakeholder feedback from Veterans, VA clinicians, and VA administrators will be collected to assess Veteran needs and service context to identify any needed adaptations to the CDST manual or the delivery of CDST to maximize its impact and feasibility. The developers of CDST will review all feedback and make final decisions about adaptations to ensure that CDST retains its essential components to protect against loss of efficacy. For example, a recommendation to adjust role-play topics to better reflect the needs of Veterans would be accepted because it would increase CDST's relevance without impairing its integrity, but a recommendation to remove all role-plays would not be accepted because it would cause loss of a key component. Second, CDST will be compared to active control (AC) using a randomized clinical trial of 72 Veterans. The primary outcome measure will be functioning within the rehabilitation context, operationalized as frequency of Veteran CDM behaviors during Veteran-provider interactions. Secondary outcomes are treatment attendance, engagement, satisfaction, and motivation, along with treatment outcomes (i.e., rehabilitation goal attainment, sense of personal recovery, symptom severity, and social functioning). Three exploratory outcomes will be assessed: Veteran-initiated collaborative behaviors, acute service use and provider attitudes and behavior. Veterans will be randomly assigned to CDST or AC conditions. Veterans in the both groups will attend eight hour-long group sessions held over eight weeks. All Veterans will complete an assessment battery at baseline, post-intervention, and at three-month post-intervention follow-up. Following the trial and adaptation phase, the findings will be used to develop a CDST service delivery manual and design a logical subsequent study. The results of the proposed study will inform the potential for larger trials of CDST and the utility of providing CDST broadly to Veterans with SMI. The results of this study will expand current understanding of CDM among Veterans with SMI by providing data that will: 1) identify adaptations needed to optimize CDST for Veterans receiving services in PRRCs; 2) identify possible benefits of CDST; 3) inform development of alternate interventions or methods to improve CDM; and 4) further elucidate CDM and associated treatment processes among Veterans with SMI receiving VA rehabilitation services.
To compare two evidence-based treatments, Cognitive Enhancement Therapy (CET) and Social Skills Training (SST) that have been shown in meta-analyses and in our own research to be effective to improve community functioning. The investigators will test the impact of CET and SST on community functioning, with special attention to their relative effectiveness for patients differing in baseline cognitive skills and age. The research uses a cluster design in which different mental health service centers are randomized to one of the two treatments.
Treatment of depression with repetitive transcranial magnetic stimulation (rTMS) has shown high evidence using high-frequency left dorsolateral prefrontal cortex (DLPFC) stimulation. The treatment of negative symptoms with the same protocol in schizophrenia is considered as possible effective. Theta burst stimulation is a new protocol which is characterized by shorter sessions showing first evidence that it's efficacy is comparable to the high-frequency rTMS. In this randomized placebo-controlled study the efficacy of high-frequency rTMS and TBS are evaluated.
Treatment decision-making capacity ('capacity') refers to a person's ability to make decisions about their treatment. It is an important issue for people diagnosed with a schizophrenia-spectrum disorder ('psychosis') because impaired capacity can mean a person does not understand what treatment options are available, or the implications of those options. In 2018 the National Institute of Health & Care Excellence (NICE) called for clinical trials of interventions such as talking therapies to help people regain capacity. However, running these trials can take several years. One way of reducing this delay is to run several trials at the same time, as part of one bigger trial called an 'Umbrella' trial. Although Umbrella trials have been used to accelerate the development of physical health interventions, they have yet to be used in mental health. The main aims of this study are therefore to find out whether people with non-affective psychosis (schizophrenia-spectrum disorder) will take part in a single (rater) blind Umbrella trial of talking therapies to improve their treatment decision-making capacity (the DEC:IDES trial), and to understand their experiences of participation. Before a larger version of the DEC:IDES trial can begin, it needs to be established that people with psychosis will want to take part in it. Specifically, the aim of this study is to establish whether they will stay in the trial until it is finished, or whether they will leave early. It will also examine why people might leave DEC:IDES early, so that it can be improved. For these reasons, a smaller version must be completed first. This will involve 3 small clinical trials, each with N=20 (Treatment N=10; Control N=10), each testing 1 of 3 different interventions. Each intervention has been designed to help participants resolve a problem which previous evidence suggests may reduce their decision-making ability. One intervention is designed to improve self-esteem, another is designed to reduce negative beliefs about psychosis ('self-stigma') and another is designed to help people with psychosis gather more information before making decisions. The investigators will record how many people participate in and complete the trial, and they will ask people for their views on what they liked and did not like about taking part. All this information will help ensure the larger DEC:IDES trial is more acceptable to people with psychosis.
The aim of the study is to check the role of the cerebellum in time prediction in healthy volunteers, by means of magnetic transcranial stimulation targeted on the cerebellum, and recording of behavioural measures indexing time prediction
