The Efficacy of Metacognitive Skills Training in the Context of Forensic Psychiatric Care

Start date: September 1, 2023
Phase: N/A
Study type: Interventional

Deficiencies in social cognition are part of the core symptomatology of psychotic disorders. And deficiencies in social cognition, the closely related concept of metacognition, and, for example, paranoid attitudes are all associated with violence. The link between social cognition and violence is also observed through rehabilitation, as both group-based Social Cognition Interaction Training (SCIT) and group-based Metacognitive Skills Training (MCT) have reduced violent behavior in patients with psychotic disorders. Thus, a better knowledge of social cognition and its rehabilitation in psychotic disorders can help to reduce risky behavior and to rehabilitate the significant social difficulties often found in psychotic disorders. This research study aims to examine factors underlying the efficacy of group-based MCT. The goal of the metacognitive skills training group developed by Moritz and partners is to strengthen the social and metacognitive skills of the patients participating in the group. The group consists of 10 sessions during which exercises and discussion are emphasized. The themes of the group sessions are, for example, jumping to conclusions -bias, empathy, and memory. Detailed information is available from the MCT website (https://clinical-neuropsychology.de/metacognitive_training-psychosis/). Overall there is meta-analysis-level evidence for the moderate effectiveness of MCT on positive symptoms of psychotic illnesses, such as delusions. Prior studies have argued that the unique factor underpinning MCT's efficacy is its impact on various cognitive biases, and that participating in the group especially reduces patients' tendency to jump to conclusions, which is a cognitive style associated with delusions and deficits in social perception and reasoning. As delusionality is related to the risk of violence, these results form a logical link between jumping to conclusions, delusionality, and violence. But the results regarding the effectiveness of MCT are still somewhat conflicting, and studies seem to be of varying quality. Additional longitudinal research and research related to the jumping to conclusion bias are also needed. The hypothesis regarding this study is that the MCT group reduces patients' tendency to jump to conclusions. These reductions are presumed to be associated in one-year follow-up with fewer mood symptoms, delusions, paranoia, and more psychological flexibility.

NCT ID: NCT05034523 Not yet recruiting - Clinical trials for Psychotic Depression

Voxel Based Morphometry In Patients With Psychotic Versus Non Psychotic Depression

Start date: September 1, 2021
Phase:
Study type: Observational

1. To examine structural brain changes in patients with depression measured using voxel based morphometry(VBM) in comparison with healthy subjects. 2. Relation between grey mater volume (GMV) and other structural changes, and the severity of clinical symptoms. 3. To study if there is structural brain difference between psychotic and non-psychotic depression

NCT ID: NCT02782442 Completed - Schizophrenia Clinical Trials

Cognitive Training Delivered Remotely to Individuals With Psychosis (ROAM)

Start date: September 1, 2016
Phase: N/A
Study type: Interventional

Primary study: This study is a single-site, double-blind, randomized, controlled clinical trial to compare an evidence-based structured program of 30-35 hours of on-line cognitive and social cognitive training exercises performed over 16 weeks (~2 hours per week), delivered with an innovative digital app which provides users with a motivation coach to set personalized goals and with secure social networking for peer support, "PRIME" ; vs. 2) A control condition of computer games, encouraged at ~2 hours per week over 16 weeks, delivered with "PRIME". Unblinded Cognitive Training Sub-Study: Participants who were randomized to the computer games arm of the trial may be offered access to the active cognitive training at the end of their 6 month follow up appointments, if they still meet inclusion criteria. PRIME Super Users Sub-Study: Participants who have provided all follow up data to the initial study, including those who are currently enrolled in the Unblinded Cognitive Training sub-study, may be offered continued participation in the PRIME community as super-users.

NCT ID: NCT01427608 Completed - Clinical trials for Psychotic Depression

Sustaining Remission of Psychotic Depression

STOP-PD
Start date: October 2011
Phase: Phase 4
Study type: Interventional

The acute phase of this study will monitor the response to a combination of an atypical antipsychotic medication olanzapine with an antidepressant medication sertraline in the acute treatment of the disorder. It is predicted that this combination will improve symptoms of psychotic depression and be associated metabolic side effects. Factors that moderate tolerability will be monitored. Improvement in symptoms could take between 4 and 12 weeks, followed by a period of 8 weeks during which participants will continue to take the same medications to stabilize the remission from symptoms of psychotic depression. The maintenance phase will be a randomized, double-blind, placebo-controlled study of olanzapine for a period of up to 36 weeks to test whether continuing this combination decreases the risk of relapse and whether discontinuing the combination leads to improvement in metabolic measures. Subjects who complete the acute phase will be asked to consent separately to the randomized maintenance phase.

Quetiapine in the Treatment of Psychotic Depression - a Pilot Study

Start date: September 2008
Phase: Phase 3
Study type: Interventional

Atypical antipsychotics have been found not only to be beneficial in the treatment of psychotic disorders, but even for depressive symptoms in patients with schizophrenia. Remarkably, preliminary data suggest that the atypical antipsychotic quetiapine has antidepressive properties. Until now, there is limited knowledge concerning the efficacy of quetiapine in major depressive illness and especially in psychotic depression. In our own clinical practice, several patients with psychotic depression were successfully treated with quetiapine as add-on therapy or as monotherapy. On the background of that, the convincing effects of quetiapine in bipolar depression, single-case reports and pilot studies concerning its effectiveness in depressive mood states in psychotic disorders as well as our clinical experiences, it is to assume that a treatment with quetiapine over a 6 weeks period show similar effects in major depressive episode with psychotic features, i.e. psychotic depression. In this pilot study we plan to investigate 20 patients with psychotic features of depression under treatment with quetiapine.

NCT ID: NCT00637494 Terminated - Psychosis Clinical Trials

A Study of Mifepristone vs. Placebo in the Treatment of Patients With Major Depression With Psychotic Features

Start date: March 2008
Phase: Phase 3
Study type: Interventional

Approximately 450 patients will be randomized to receive Mifepristone or placebo for 7 days followed by antidepressant. The purpose is to compare the efficacy of Mifepristone followed by antidepressant versus placebo followed by antidepressant in reducing psychotic symptoms in patients with a diagnosis of psychotic depression.
