Filter by:Although psychotic disorders typically affect less than 1% of the population, they are a significant cause of disability worldwide. Psychotic symptoms such as hallucinations, delusions and suicidal ideation can be profoundly disturbing, and negatively impact daily living. However, the social consequences of psychosis are often even more troubling than the symptoms. For example, people with psychosis have a high risk of experiencing violence, poverty, homelessness, incarceration, and unemployment, among other adverse outcomes. There is a need for a range of accessible, appropriate interventions for people with psychosis to be delivered to those in the most vulnerable situations, including in low-resource settings in sub-Saharan Africa. A systematic review recently carried out as part of the formative research for SUCCEED identified 10 studies evaluating the impact of interventions for people with psychosis in Africa, most of which had a strongly clinical focus. The review concluded that there was a need for further research involving people with lived experience of psychosis in designing and evaluating holistic interventions that meet their diverse needs, within and beyond the health sector. SUCCEED Africa is a six-year Health Research Programme Consortium (RPC) that has brought together people with lived experience of psychosis and people with professional experience (researchers, clinicians) from four African countries (Malawi, Nigeria, Sierra Leone, Zimbabwe) to co-produce a community-based intervention for psychosis, using a Theory of Change-driven approach. The SUCCEED intervention takes the World Health Organisation's (WHO's) CBR Matrix as a point of departure to consider the multifaceted needs of people living with psychosis and other psychosocial disabilities, and how best to meet these needs by mobilising the resources of individuals and families affected, as well as their broader communities. This protocol describes a pilot study in which the SUCCEED intervention will be delivered and evaluated on a small scale, in preparation for a larger multi-country research evaluation using more rigorous methods, including randomised controlled trials in Nigeria and Zimbabwe and observational studies in Malawi and Sierra Leone, respectively. The main outcome of interest is change in subjective quality of life among participants with lived experience of psychosis who are offered the intervention over a four-month follow up period.
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.
This study aims to provide an evidence-based behavioral intervention to reduce violent behavior for individuals experiencing early psychosis.
The OPUS YOUNG (OY) study investigates the efficacy of early intervention service versus treatment as usual (TAU) for adolescents aged 12-17 years with a first-episode psychosis. In Denmark, the yearly incidence of schizophrenia in youth below the age of 18 years has increased from 137 in 2000 to 477 in 2016. Outcomes in people with schizophrenia spectrum disorders are suboptimal with low quality of life, low rates of recovery, substance misuse, higher rates of suicide, violence and legal problems, low educational and vocational attainment, and a significantly reduced life-expectancy of 15-20 year. Schizophrenia imply a large burden of disease with severe impact on patients, their families, the service system and a large economic societal burden. The investigators will include 284 participants age 12-17 years with an early onset psychosis within the following diagnostic classes: schizophrenia spectrum, psychotic depression or drug-induced psychosis. The design is an independent, investigator initiated, pragmatic, randomized clinical trial, with blinded outcome assessment. Participants are randomized 1:1 to OY or TAU. Participants in OY are offered 2 years of specialized intervention (OY) regardless of age, while participants in TAU are switched to adult psychiatry at the age of 18 years. OY builds on the Danish evidenced based intervention for young adults, OPUS, adjusted to meet the specific needs of adolescents: intensified support for caretakers and relatives including siblings; social cognition and interaction treatment; and individual cognitive behavioral case management. OY addresses the specific challenges of psychopharmacologic treatment in youth; supported transition to adult care after OY; school or educational support; and prevention and treatment of substance misuse. The primary endpoint is improved functioning in daily and social life after 24 months. Secondary outcome measures are psychopathology, quality of life, family stress, and retention in treatment and school/employment, and healthcare consumption. The clinical and societal perspective of a large scale implementation is improved prevention of the negative consequences of early-onset psychosis and a reduced burden of severe mental illness.
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.
The study examine the effectiveness of an integrated care program including therapeutic assertive community treatment (ACT) for people with psychotic disorders fulfilling severe and persistent mental illness (SPMI, ACCESS-II study).
In the last decade cognitive behavioural therapy (CBT) approaches for patients with schizophrenia have been developed, which where especially designed to reduce severity of positive symptoms, readmission rates, treatment non-compliance and disability. Although CBT addresses the key problems of early onset psychoses (EOP)treatment and first evaluations of CBT in adults with schizophrenia are promising, no experience with CBT in adolescents with EOP are available. Therefore the present study is conducted to develop a modified CBT (mCBT) for adolescents with EOP, to explore its acceptance and feasibility and to provide data for a realistic estimation of achievable effect size. Patients are randomized to receive either mCBT+TAU or TAU over a 9 month period. mCBT is an individual outpatient treatment of 20 session and 5 psychoeducational sessions with parents. Follow-ups for two years every 6 months are planned.
The following study addresses the hypothesis that cognitive-behavioral interventions will be effective in reducing positive and negative symptoms of schizophrenia under the conditions of the German health care system. It is also hypothesized that interventions designed to reduce delusions will reduce cognitive biases and dysfunctional self-concepts.
