Online Intervention To Improve Motivation

Participants will complete one online intervention lasting 12 weeks. Each week, they will be asked to complete a 20-30 minute session online. The intervention is targeting improved mood and positive affect in order to support increases in motivation and goal-directed behavior. Before and after the intervention, participants will be asked to complete measures to assess symptoms, mood, and behavior.

Non-invasive Brain Stimulation Using Tdcs of the Third (of Many) Visual Pathways

This study investigates the ability of transcranial direct current stimulation (tDCS) applied over the motion processing area of the brain (area MT) to improve face emotion recognition (FER) ability. tDCS is a type of non-invasive brain stimulation in which low level currents are applied over the scalp to influence underlying brain function. In schizophrenia, impaired ability to detect facial motion has been shown to contribute to impaired FER, which, in turn, leads to difficulties in social cognition and poor social outcome. The study will use both fMRI and EEG to measure brain function while participants view moving dot and dynamic face stimuli. Analyses will compare changes in fMRI and EEG activity in individuals receiving active vs. sham stimulation.

Feasibility, Acceptability, and Effectiveness of a Hatha Yoga-in Patients Hospitalized for Schizophrenia

The current study aims to examine the feasibility, acceptability, and preliminary effectiveness of a Hatha yoga-based group intervention on reminiscence functions and mindfulness in a sample of patients hospitalized for schizophrenia.

Cognitive Rehabilitation With Immersive Virtual Reality (IVR) in Schizophrenia: a Pilot Randomized Waiting List Controlled Feasibility Study

Virtual reality-based rehabilitation has recently gained increasing attention in the field of cognitive rehabilitation, allowing patients to engage in simulated real-life scenarios within a safe and controlled setting. The feasibility and safety of immersive VR-based cognitive rehabilitation in individuals with schizophrenia is currently insufficiently explored. This study seeks to evaluate whether immersive immersive virtual reality-based rehabilitation can be safely and practically implemented in a community psychiatric setting. The study also aims to explore preliminary effects on negative symptoms, cognitive performance, and global functioning compared with treatment as usual in a waiting-list control group.

A PET/MRI Study of Cobenfy on Dopamine Transmission in Schizophrenia

This is a single site clinical trial in which 12 participants with schizophrenia will be randomized to one of three doses of treatment with Cobenfy for 5 weeks. \[18F\]DOPA PET scans will be obtained before and after treatment to examine the effects of Cobenfy on dopamine transmission. The overall objective of the current study is to measure Cobenfy's ability to engage its putative target (DA transmission/synthesis capacity in the striatum and midbrain as measured by \[18F\]DOPA Kicer (\[18F\]DOPA relative uptake rate)).

Efficacy of Pediococcus Acidilactici as add-on to Antipsychotic Drugs on Metabolic Syndrome Disturbances in First-episode Psychosis and Schizophrenia Spectrum Disorders. A Double-blind Placebo-controlled Trial.

The aim of the present study is to evaluate the effectiveness of the addition of the postbiotic Pediococcus acidilactici (pA1c®HI) on amelioration of metabolic disturbances in patients with (FEP) or (SSD) treated with antipsychotic drugs.

PS-Trauma - Development of Trauma Treatment for Patients With Co-morbid Psychotic Disorders and Traumas

Overview: People with psychotic disorders frequently have a history of traumatic events such as neglect, bullying, or physical and sexual abuse. Many experience significant symptoms of post-traumatic stress, but trauma-focused treatment is rarely offered in standard psychiatric care. This pilot study investigates whether two established trauma therapies can be delivered safely and acceptably to young adults with psychotic disorders receiving care in the OPUS early-intervention program. Objectives: The main aim is to evaluate the feasibility and acceptability of two trauma-focused treatments-Prolonged Exposure (PE) and Eye Movement Desensitization and Reprocessing (EMDR)-in patients with psychotic disorders and post-traumatic stress symptoms. The study is not designed to test treatment efficacy but to determine whether a larger randomized controlled trial is practical. Study Design: This is a pilot and feasibility study. Twenty OPUS patients with a diagnosis within the schizophrenia spectrum and clinically relevant PTSD symptoms will be randomly assigned to either PE or EMDR. All participants continue their usual OPUS care while attending weekly trauma-focused therapy sessions. Assessments: At baseline and follow-up, participants complete clinical interviews and questionnaires assessing trauma symptoms, psychotic symptoms, functioning, well-being, recovery experiences, and possible negative effects. Instruments include the PCL-5, CAPS-5, Mini-TALE, PANSS-6, PSP, WHO-5, Brief INSPIRE-O, NEQ, and CSQ. Primary Feasibility Outcomes: Recruitment: At least 80% of the planned sample enrolled within 6 months. Retention: At least 70% completing ≥12 therapy sessions. Acceptability: Participant satisfaction measured with the Client Satisfaction Questionnaire (CSQ). Eligibility: Inclusion: Age ≥18 Diagnosis within the schizophrenia spectrum (ICD-10: F20-F29) PTSD symptom score \>31 on PCL-5 Current OPUS patient Sufficient Danish language skills Exclusion: Substance use that prevents participation (e.g., attending sessions intoxicated) Severe cognitive impairment Recent changes in antipsychotic medication (within 1 month) Risks and Safety: Temporary increases in PTSD symptoms may occur when beginning trauma therapy; this pattern is well documented and typically followed by improvement. Previous studies show no higher risk of serious adverse events among patients with psychosis receiving trauma treatment compared with those who do not. Participants are closely monitored, and the study team works in continuous collaboration with OPUS clinicians. If a participant experiences significant clinical deterioration, the therapy can be paused or stopped, and supportive measures will be provided. Potential Benefits: Participants may experience a reduction in trauma-related symptoms and gain access to a treatment that is not otherwise routinely offered to patients with psychotic disorders. The study may help improve future care for this underserved population. Funding: The study is funded by the Nektar Foundation and conducted at the CORE Research Unit, Mental Health Services Copenhagen.

The Effects of a Solution-Focused Approach on Psychosocial Adjustment and Treatment Compliance in Individuals Diagnosed With Schizophrenia

The aim of this study is to evaluate the effects of a solution-focused approach-based individual intervention on psychosocial adjustment and treatment adherence in individuals diagnosed with schizophrenia. The study will be conducted as a randomized controlled trial including 60 clinically stable individuals diagnosed with schizophrenia according to DSM-5 criteria and registered at a Community Mental Health Center affiliated with a university hospital. Participants will be randomly assigned to an experimental group (n=30) and a control group (n=30). The experimental group will receive one individual solution-focused therapy session per week for six weeks. The control group will receive usual care only. Data will be collected using a Personal Information Form, the Psychosocial Adjustment Scale (PSSAS), and the Medication Adherence Scale (MARS).

Disorders of the Sense of Self and Physical Activity

Schizophrenia (SZ) patients with metabolic syndrome, patients with vestibular syndrome, and patients with borderline personality disorder, would benefit from physical activity (PA). Yet patient adherence to PA is low, at least in the case of SZ. the investigators work and the literature lead the investigators to consider that, in addition to motivational aspects, disorders of the bodily sense of self could play a role in this lack of adherence. Simply walking involves visual movements related to the self, which must be distinguished from movements in the environment. This means a distinction between self and not-self. Furthermore, these movements are all the more difficult to distinguish as they may also result from the fact that hidden objects become visible as a result of our own movement. In all sense-of-self disorders can themselves affect physical training, and the investigators will measure them in the first stage. In the second stage, the investigators will apply a standard, risk-free PA protocol by walking (3x3 sessions of 30 min). the investigators will test the impact of physical training on the sense of self under different conditions, with one environment minimizing self-related movement, vs. 2 environments with a variable level of enrichment (i.e. hidden objects inducing more or less self-related movement). At the end of the protocol, the investigators will offer participants who wish to take part in an ancillary study, i.e. a walking session with mixed-reality goggles. These will superimpose a luminous flux on the periphery of the visual field. According to results obtained in the laboratory, this flux could restore sensory mechanisms impaired in schizophrenia. the investigators will use these glasses in the most difficult condition for the patient, and verify their impact.
