Filter by:Connection to Environment with Cognitive Therapy (CONNECT): A Single-Case Experimental Design Exploring Dissociative Experiences and Voices Emerging empirical evidence has suggested that dissociation is a robust determinant of voice-hearing in psychosis, and that dissociation mediates the link between trauma and voices. Despite the emerging evidence-base, targeted therapeutic interventions focusing on dissociation remain largely untested. The aim of the current study is to investigate whether targeting dissociation leads to improvements in distressing voices in people with a history of trauma. This will be done by delivering an eight session intervention called 'CONNECT' to six individuals within the Glasgow Psychological Trauma Service (GPTS) who hear voices, have experienced trauma and are dissociating. The intervention will focus on learning strategies to manage dissociation. It is hypothesised that reduced levels of dissociation will be associated with reduction in the frequency and distress associated with hearing voices. This study will use a randomized multiple baseline single-case experimental design, meaning that participants will be randomly allocated to a baseline of two, three or four weeks and then will begin eight weeks of Connection to Environment Cognitive Therapy (CONNECT). As well as daily measures during baseline and intervention phases, there will be four assessment points (baseline, pre-intervention, post-intervention and follow-up). The study will take approximately three months plus follow-up one month after therapy ends. Individual levels of dissociation and voices will be compared during baseline and intervention periods using visual analysis and Tau-U. This study will contribute to the evidence-based for dissociation interventions targeting distressing voices among this population. It serves to investigate the proposed mechanism in a clinical population using a therapeutic intervention. It will therefore inform clinicians of the effectiveness and feasibility of using such strategies in clinical practice and may have good generalizability to practice.
The Unified Protocol (UP) is an emotion-focused, cognitive-behavioural intervention that is developed to target core temperamental characteristics underlying anxiety and depressive disorders. Ehrenreich and colleagues developed UP for adolescents (UP-A). The current study aims at evaluating efficacy of UP-A for the treatment of emotional disorders in Chinese adolescents in Hong Kong. The current study would recruit 27 Chinese-speaking patients, age 13 to 18, with a primary diagnosis of any Diagnostic and Statistical Manual (Fifth edition) anxiety disorders and/or depressive disorder. They would be randomized into one of the two treatment arms, namely UP-A treatment condition (UP-A), and treatment-as-usual (TAU) condition. Following randomization, participants in the UP-A condition would attend individual treatment based on UP-A, which last for 10 to 12 weeks. Participants in the TAU condition would be provided with usual clinical psychological service (i.e. treatment as usual) in the first 12 weeks before they start attending the same individual treatment program. Primary outcomes would be patient's self-rated measures on clinical symptoms, and secondary outcomes would be their clinical diagnoses, parent-rated and other self-rated measures. It is hypothesized that, comparing to those in TAU, participants in the UP-A condition would show improvements in depressive symptoms, anxiety symptoms and functional impairment at the end of treatment. When the outcomes of all participants are combined, it is hypothesized that participants will show demonstrate improvement in depressive symptoms, anxiety symptoms, and functional impairment after completing the UP-A and at the 3-month follow-up.
This study is a waitlist control trial evaluating the acceptability and preliminary efficacy of a smartphone application with people with mental illness.
The study aimed to investigate the effects of high-definition transcranial random noise stimulation over bilateral prefrontal cortex on psychopathological symptoms, other clinical outcomes, autonomic functioning ,and brain oscillatory activity in schizophrenia patients.
Deficits or abnormalities in reward processing are present in a number of psychiatric disorders. The overarching objective of the study is to conduct initial validation work towards optimising three experimental tasks - which have previously been shown to be sensitive to reward processing deficits - for future use in clinical trials. This initial validation work has the primary objective to uncover group differences in task outcome measures between healthy control participants, participants with Major Depressive Disorder (MDD) and participants with schizophrenia (SZ) using statistical analyses. This may provide some indications for the use of these tasks as clinically-relevant biomarkers. Primary aims include: (i) comparing the investigator's endpoint means and distributions to those in previously published data; (ii) replication of previously-reported differences between MDD/SZ vs. healthy control participants, and, (iii) exploring the relationship between task endpoints and subjective participant- and clinician-rated report of reward-related constructs (e.g. anhedonia, negative symptoms).
The goal of this study is to pilot test a culturally tailored Family Psychoeducation model (KUPAA) for adults with psychotic disorders and their relatives that is appropriate for cultural settings inclusive of both traditional and biomedical ideas about mental illness and that incorporates relatives as co-facilitators of the intervention.
Approximately 60 chronic smokers with bipolar disorder, schizophrenia or schizoaffective disorder who are motivated to try to quit smoking will be randomized to receive smoking cessation treatment with the FDA-approved medication, varenicline, delivered either a) at its standard dose and titration schedule (half of the participants) versus b) at a lower dose and slower titration schedule (the other half), for 12 weeks. All smokers will choose a target quit date sometime between 8 to 35 days after starting the medication. All participants will receive ten 30-minute sessions of a behavioral treatment called Acceptance and Commitment Therapy (ACT). Participants will be followed for an additional 12 weeks off study medication. The major endpoint is the feasibility of combining ACT with the different dosing strategies. Investigators will also conduct a blood test that measures the breakdown of nicotine in the body to explore whether that measure influences treatment response and side effects.
The study population for this research will include parents and concerned significant others (PCSO) of individuals experiencing recent (past five years) onset of a psychotic disorder (hereafter referred to as individuals with psychosis, "IP") who are not currently engaged with, or at risk for disengagement from, treatment. MILO is a brief and structured intervention that teaches motivational interviewing communication strategies. The initial aim (phase 1) of this pilot study is to evaluate feasibility of the intervention. The secondary aims are to evaluate the effectiveness of MILO for (1) enhancing the engagement of IP with evidence-based treatments and (2) reducing distress among PCSO. The investigators hypothesize that the intervention will be superior to control condition for both enhancing IP engagement with mental health services and reducing PCSO distress.
Schizophrenia (Schizophrenia,Sc), biphasic affective disorder (Bipolar disorder,BPD), major depression (major depressive disorder,MDD), anxiety disorder (Anxiety disorder,An) and other mental disorders have obvious family aggregation, with heritability of 60 -90%. This kind of common mental illness seriously affects the psychosomatic health and quality of life of patients, and places a great mental and economic burden on the society and family. At present, the diagnosis of mental illness is mainly based on clinical symptoms. With the development of molecular biology, genomics has become a new way to study mental illness. MicroRNA (miRNA) is a class of eukaryotic endogenously non-coding single-stranded RNA, which can regulate gene expression by binding to specific mRNA or regulating the protein translation process of specific mRNA. MiRNA widely exists in plasma and serum, and the type and quantity of miRNA in plasma and serum change with different physiological and disease conditions. It is reported that the expression profile of miRNA in brain tissue of schizophrenia is significantly different from that of normal subjects. In addition, the study found that the specific miRNA detected in peripheral blood can directly reflect the condition of the disease, which may use miRNA in peripheral blood as a clinical biological marker. In order to detect the expression of various miRNA in plasma, high throughput miRNA chip detection has become the first choice for primary screening. In this study, the investigators intend to detect the difference of miRNA expression in peripheral blood of different types of schizophrenia by high throughput miRNA chip, and analyze the correlation between them. It is hoped to provide the basis for the diagnosis and occurrence and development of clinical psychotic patients.
This clinical trial aims to evaluate the effects of an art therapy intervention carried out in museums to facilitate the process of recovery in mental health. In total 100 users of mental health services will be recruited for this study. Participants in the trial will be assessed at baseline and at 3 months.
