Filter by:This study aims to test the feasibility and acceptability of a brief behavioral intervention that combines two treatments, Motivational Interviewing (MI) and Cognitive Behavioral Therapy (CBT), that have been shown to work in prior research studies. The format of the intervention will be a combination of in-person sessions and remote elements delivered via mobile phone (together called MI-CBTech). The goal of the intervention is to improve community integration in Veterans with serious mental illness (SMI) who have experienced homelessness. A time- and format-matched control arm will include remote mindfulness training. 50 Veterans with SMI experiencing homelessness will be randomized to one of the two arms (25 per arm).
The effectiveness of current treatment options for sociocognitive deficits and negative symptoms (NS) in schizophrenia spectrum disorders (SSD) remains limited. The cause of NS is thought to be an interference between the mesocorticolimbic dopamine system for social reward expectancy and the network for socioemotional processes. Oxytocin (OXT) may enhance functional connectivity between these neuronal networks. Lower plasma OXT levels correlate negatively with NS severity and deficits in social cognition in SSD. It has been shown that intranasal OXT administration improves social cognition in healthy subjects but in SSD results are inconsistent. According to the social salience hypothesis, the effect of OXT varies depending on the social context and individual factors. Also, OXT-mediated effects on psychopathology and NS may depend on genetic variants of OXT receptors (OXTR). In a pilot study, the investigators demonstrated a lower NS by OXT administration in the positive social context of MBGT in SSD. The investigators also demonstrated that NS and other symptoms improved after mindfulness-based group psychotherapy (MBGT). The aim of this study in individuals with SSD is to examine the effect of combining OXT administration with MBGT on NS, affect, and stress with psychological and biological markers. The main hypothesis to be tested is that the use of OXT compared to placebo prior to MBGT in patients with SSD will result in a greater reduction in NS. The research design is based on an experimental, triple-blind, randomized, placebo-controlled trial.
Cognitive symptoms of schizophrenia interfere with daily life-from managing self-care, to more complex tasks like taking medications and living independently. Unfortunately, these cognitive symptoms are not corrected by 'standard of care' treatments (antipsychotic medications), although some schizophrenia patients may experience modest clinical and cognitive benefits from cognitive remediation. To enhance the clinical impact of cognitive remediation and other rehabilitative interventions for Veterans living with chronic psychosis, this study will develop novel brain-based tools to help identify those Veterans who are most likely to benefit from pro-cognitive therapies. These studies may advance predictive algorithms that improve functional outcomes and life quality in Veterans with schizophrenia.
This study is to evaluate the safety and efficacy of Virtual Reality Mindfulness in Patients With Psychosis.
Rates of obesity in patients with schizophrenia-spectrum disorder (SSD)s have reached epidemic proportions, with established contributing effects of antipsychotic (AP) medications. Among agents approved for chronic weight management, glucagon-like peptide-1 receptor agonists (GLP-1RA) are associated with reductions in cardiovascular mortality, with recent FDA approval for once weekly semaglutide for this indication. This study will investigate whether semaglutide is effective in reducing body weight in overweight or obese individuals with SSDs who are on APs and do not demonstrate adequate weight loss on metformin (the first line treatment for weight loss in SSDs).
In previous studies the neuropeptide oxytocin has been in particular associated with social enhancing and anxiety relieving effects. The purpose of this study is to investigate the effect of oxytocin on empathy in patients with schizophrenia. On a neurobiological level, social effects mediated by oxytocin are based on oxytocin's influence on the complexly regulated mesocorticolimbic dopamine system. Preliminary studies have already shown that oxytocin increases neuronal connections between social reward expectancy networks and networks for socioemotional processes in the brain, which on a behavioral level leads to increased social activation, motivation, and also improved social perception. Furthermore, an increase in empathy modulated by the amygdala has been shown in healthy individuals following oxytocin administration. In particular, primary psychotic disorders, such as schizophrenia, are associated with deficits in the domain of social cognition, including empathy, with the degree of negative symptoms playing an important mediating role. Another study demonstrated a significantly lower expression of empathy as well as a significantly lower oxytocin level in patients with schizophrenia compared to healthy subjects. According to the hypothesis of social salience, which describes an increased importance of certain social stimuli, the effect of oxytocin varies depending on specific contexts and individual variables of the perceiving person, such as the degree of negative symptoms. Therefore, based on such preliminary findings, the research project will explore an effect of oxytocin on empathy within a positively experienced and controlled context, especially in patients with schizophrenia regarding their negative symptoms.
The goal is to provide combination of 2 hours of weekly game based telehealth therapeutic intervention along with CBT-P for children identified with first onset psychosis or to be clinically high risk for psychosis thus widening therapeutic services offered. Target outcome measures are improvement in clinical symptoms, treatment engagement, and reduced hospitalization rates.
This is an observational study where digital, clinical and health utilization data are collected from individuals with schizophrenia spectrum disorders who have been recently discharged from a psychiatric hospitalization. The data will be used towards building a model/algorithm capable of monitoring mental health and predicting adverse clinical events, such as relapse and re-admissions.
A large proportion of people with a schizophrenia-spectrum disorder, especially in the early stages of the disease, regularly consume cannabis. Cannabis use is associated with poor prognostic outcome; however, there are no effective interventions targeted at reducing cannabis use or its deleterious effects in this population. The present trial is designed to test whether cannabidiol (CBD), a cannabinoid whose effects are in many ways antagonistic to those of Δ9-tetrahydrocannabinol (THC), can reduce psychiatric symptoms, cognitive deficits, and cannabis use in people with recent-onset psychosis who regularly consume cannabis.
This proposed randomized controlled trial will test the effectiveness of a problem-solving based bibliotherapy program (PSBPF) for Chinese family caregivers in schizophrenia spectrum disorders. A repeated-measures, three-group design will be used to evaluate and compare the effects between two treatment groups (PSBPF and behavioral management group) and routine outpatient service (control group) for 150 randomly selected family caregivers of outpatients with schizophrenia-spectrum disorders over a 18-month follow-up.
