The GENESIS study is a multicenter, prospective, non-interventional, clinical study with a target of 12,000 subjects and an anticipated total duration of 36 months. The aim of study GENESIS is to provide a pilot map of HLA genetic variation in the Greek population in order to be used in medical research and for possible clinical applications (evaluation of possible correlations with selected underlying diseases). During the study, each subject will conduct one visit to the participating cite, in which they will provide: 1. Demographic information \[i.e. date of birth, gender, race, ancestry (including information about the subject's grandparents' birthplace), height, weight\], 2. Other information about smoking/vaping, alcohol consumption, arterial blood pressure, diagnosed diseases (if any), current treatments (if any), and 3. Recent (up to 12 months prior to sample collection) results if/when are available from clinical lab tests such as blood count (Hct, Hb, RBC, WBC, PLT count), including a metabolic panel, liver enzymes and biochemical parameters (Glu, HbA1c, TC, TG, LDL-C, HDL-C, ALT, AST, ALP, γGT, bilirubin, LDH, insulin, C-peptide). Upon completion of the data registry, two buccal swabs will be collected per subject and they will be stored at ALTP premises until their shipment to Galatea.Bio. All buccal swab samples will be subjected to genetic material (DNA) extraction. The DNA samples will be further proceeded for HLA genotyping analysis. A follow up analysis will be performed in selected DNA samples via full low-pass whole genome sequencing (LP-WGS), which aims to further investigate the association between the HLA region and autoimmune diseases. Upon completion of the analysis, an individualized ancestry report will be securely made available to all study subjects which they can access, as and if they elect to.

BACKGROUND Population surveys indicate that people generally hold distorted views and negative stereotypes about individuals suffering from mental disorders. For example, 60% of the population believes that patients with mental disorders are aggressive or violent, and 50% believe they are incapable of working. Research has also found that most individuals with mental disorders are aware of the presence of these stereotypes in society, and over 70% expect to be treated unjustly by others because of their condition. Additionally, 60-70% of patients with mental disorders believe that most people would refuse to have someone with a mental disorder as a friend, neighbor, colleague, or partner. While some individuals with mental disorders may react to these stereotypes with indifference or anger, most end up accepting these stereotypes as true, internalizing them and attributing them to themselves; this phenomenon is known as internalized stigma or self-stigma. One of the largest studies in this field estimated that 41% of individuals with schizophrenia spectrum disorders experience high levels of self-stigma. Other studies have reported similar rates. The literature has found that self-stigma is associated with worse recovery outcomes. A recent meta-analysis reports significant correlations between self-stigma and a lack of hope, self-esteem, and self-efficacy, poorer subjective quality of life, greater symptom severity, and lower treatment adherence. Self-stigma can be both a consequence and a cause of negative outcomes. When self-stigma plays a causal role, it can become a target for treatment. Yanos and colleagues proposed the illness identity model which provides a set of detailed and testable hypotheses regarding the potential causal role that self-stigma plays in influencing recovery outcomes in individuals with mental disorders. This model suggests that when identity is influenced by self-stigma, individuals believe that recovery is not possible, reducing hope (i.e., expectations about one future) and self-esteem. Despair and low self-esteem, in turn, increase the risk of suicide, reduce social interaction, lead to the use of passive coping strategies for symptoms, and reduce treatment adherence. As patients use avoidant coping strategies, they may also lose their jobs. Finally, avoidant coping, social isolation, and reduced social functioning can increase the severity of psychotic symptoms. Empirical support for this model comes from the findings of two studies conducted by different research groups. Building on the evidence of the role that self-stigma plays in recovery processes, Narrative Enhancement and Cognitive Therapy (NECT) was developed as a treatment protocol aimed at reducing self-stigma in individuals with mental disorders. NECT is a structured group treatment that combines psychoeducation (to help participants challenge stigmatizing beliefs about mental illness and recovery with empirical and scientific data), cognitive restructuring (aimed at teaching skills to modify negative beliefs about oneself related to stigma), and narrative enhancement (designed to help participants improve their ability to integrate themes like trust and self-worth into their narratives). To date, five studies have tested the effectiveness of NECT. The first, conducted in the United States with a small group of 39 patients, failed to highlight significant effects of NECT on self-stigma, likely due to the small sample size; however, the intervention was found to be feasible and well-tolerated by participants. A study conducted in Israel with 119 patients showed that participation in the NECT program was associated with significant improvements in self-esteem, quality of life, and hope. Similarly, a randomized controlled trial with a 6-month follow-up conducted in Gothenburg, Sweden, found that the NECT intervention was associated with significant improvements in self-esteem and self-stigma, and that these improvements were maintained at six months. A subsequent randomized controlled study conducted in the United States with 170 patients with schizophrenia spectrum disorders demonstrated that NECT could produce significant improvements in self-stigma and other variables, including avoidant coping, compared to the supportive control intervention. Finally, a randomized controlled trial implemented in Taiwan showed more significant results from NECT in improving self-esteem and reducing perceived discrimination compared to the control intervention. These studies demonstrate that NECT's effectiveness is supported by robust empirical evidence, qualifying it as an evidence-based intervention and suggesting its large-scale implementation. Unfortunately, in Italy, interventions against self-stigma in individuals with mental disorders are not regularly provided. Where anti-self-stigma interventions are offered, they are generally not based on solid evidence of effectiveness. This delay is due to the unavailability of manualized interventions, such as NECT, in our language. Moreover, the anti-self-stigma interventions published in the literature have so far been tested in geographical contexts and within healthcare organizations very different from those in our country. Therefore, it is unclear how these interventions, if made available in Italian, could be applicable within our healthcare settings. OBJECTIVES The objectives of this study are: (1) to evaluate the effectiveness of this approach in the clinical routine of mental health centers; (2) to test the feasibility of the new Italian version of the NECT treatment in patients who seek care at mental health centers in a large area of north-eastern Italy. Overall, this project will enhance knowledge of optimal treatments for patients with mental disorders burdened by high self-stigma, with the aim of improving their recovery outcomes. The study is a pragmatic, multicenter, randomized controlled trial with two parallel arms: intervention group and control group. INTERVENTIONS The intervention group will receive Narrative Enhancement and Cognitive Therapy (NECT), a structured group therapy aimed at reducing self-stigma in individuals with severe mental disorders. NECT, originally developed by Philip Yanos and colleagues, has been adapted into Italian for this study and consists of 20 sessions divided into five parts: orientation, psychoeducation, cognitive restructuring, narrative enhancement, and conclusion. Each part is designed to help participants reflect on their experiences, challenge self-stigmatizing beliefs, and foster a new, positive identity. The control group will continue with their usual care, which typically involves a combination of pharmacological treatment and psychosocial interventions provided by public mental health services. The study will systematically collect information about the care received by participants during the trial. STUDY DURATION AND RANDOMIZATION PROCEDURE NECT sessions during approximately one hour, structured into an introduction, a central discussion, and a conclusion. The NECT intervention is considered an add-on treatment, meaning participants will continue receiving their standard care in addition to the group therapy. The control group will continue with their usual treatment, which may include medication, symptom management, and psychiatric rehabilitation. Staff involved in delivering the NECT intervention will undergo specific training to ensure consistent and effective implementation. Treatment fidelity will be monitored through audio recordings of selected sessions, evaluated using the NECT Fidelity Scale. The study also includes a feasibility assessment, measuring participant engagement, session completion rates, and feedback from both participants and facilitators to identify factors that may impact the implementation of NECT in clinical settings. The study is designed to be completed over 12 months. It begins with protocol approval, followed by a two-month recruitment phase to enroll eligible participants. Once recruitment is complete, a five-month intervention phase will take place, during which participants will undergo the NECT treatment. The final five months are allocated for data entry, analysis, and the preparation of results for publication. The study involves 26 community mental health centers (CMHCs) across the Veneto region, the Trento province, and the city of Bolzano. The randomization process is crucial for ensuring the validity of the trial. Each CMHC will recruit 16 patients, for a total of 416 participants. They will be randomly assigned to either the NECT intervention group or a control group, maintaining a 1:1 allocation ratio. This stratified randomization by CMHC ensures that the unique characteristics of each center are accounted for, contributing to the robustness of the study's findings. The randomization will be carried out using specialized software to ensure fairness and consistency across all centers.

This 5-year study aims to refine and pilot a peer-delivered intervention to improve functional and social recovery to decrease suicide risk; the study consists of two phases. Phase 1 employs a user-centered design approach to refine SUicide Prevention by Peers Offering Recovery Tactics (SUPPORT) aided by scientific and consumer advisory board stakeholders as well as training Peer Specialists to fidelity on pilot cases in an open trial. SUPPORT is a flexibly delivered intervention intended to augment safety planning by addressing functional and social goals personalized to each Veteran's recovery following a suicidal crisis while including cognitive learning strategies to enhance recall and salience of intervention material. Following adaptations from Phase 1, Phase 2 includes a pilot randomized controlled trial of SUPPORT compared to an enhanced standard care condition. Veteran participants in both phases will be quantitatively assessed at baseline, mid-treatment, post-treatment, and 3-months post-treatment (and qualitatively interviewed at post-treatment). Peer Specialists delivering the intervention will also be qualitatively interviewed post-treatment. The primary outcomes to be evaluated is improvement in personal recovery and reduction in suicidal ideation severity. Secondary outcomes concern changes in various domains of personal and social functioning.

This is a definitive, randomized controlled trial that will measure the efficacy of Resilience Training, a four-session group-based behavioral intervention conducted in transdiagnostically at-risk young adults who have psychotic experiences. The primary goal is to determine whether Resilience Training is superior to a time-matched active control condition, Life Skills Training, in reducing transdiagnostic symptoms of psychopathology, such as psychotic experiences, and improving long-term psychiatric (preventing the onset of psychiatric diagnoses) and functional (improving academic performance and retention in college) outcomes in this at-risk population. In addition, a proposed model of the mechanisms of action of RT, involving reducing emotion reactivity and changes in hippocampal function and connectivity, will be assessed.

According to the World Health Organization (WHO), 970 million people worldwide suffer from mental disorders, many of whom are parents. Cross-sectional studies indicate that between 15-55% of the patients attending adult mental health service (AMHS) are parents. In Denmark, about 430.000 children have at least one parent with a mental disorder. Parental mental health problems have a detrimental impact on parenting, leading to long-term negative consequences for their children. Robust evidence shows that children of parents with mental disorders have an elevated risk of various adverse outcomes and events, such as developing a mental disorder themselves and exposure to child maltreatment, compared to children of healthy unaffected parents, suggesting an intergenerational transmission of adversity from parent to child. Mental disorders in parents thus leaves deep traces throughout their children's' lives and entails major socio-economic consequences. Given the high prevalence and substantial burden of parental mental disorders, there is an urgent need for evidence-based interventions targeting the specific needs of this population to prevent the adverse impact on their children. Despite this, the existing services in AMHS for parents with mental disorders are insufficient, and not evidence based. The present trial seeks to fill in this gap. This is an investigator-initiated single-center, two-arm, parallel group randomized clinical trial testing for superiority of a transdiagnostic mentalization-based intervention (Lighthouse MBT Parenting Program) versus care as usual in 170 parents with various mental disorders. The experimental intervention and active control group intervention are delivered as an add-on to the participants' outpatient treatment. Participants will be recruited from the outpatient clinics at Psychotherapy Centre Stolpegaard (PCS), Capital Region of Denmark. Participants will be included if they comply with the eligibility criteria. Participants will be assessed at baseline, and at 6, 12, and 24 months follow-up after randomization.

Paranoia involves intense fears that others intend to cause harm. This fear of being under threat and unable to trust others often causes a young person significant distress and impairs everyday functioning. Paranoia is common in adolescence (20-30% report weekly fears, rising to 35% among those seeking mental health care), occurring not only in psychosis but across a range of mental health disorders. Help-seeking adolescents with various non-psychotic conditions commonly report paranoid thoughts. Despite the prevalence and impact, there are currently no proven therapies designed specifically for young people experiencing paranoia. This trial aims to address this gap. Current treatments for paranoia focus almost exclusively on adults. In adult populations, values-based approaches and mental imagery techniques have shown promise in reducing paranoia. These interventions address underlying cognitive processes, negative beliefs about self and others, distressing mental images, and lack of values-directed behaviour, which maintain paranoid thinking. However, youth mental health interventions require developmentally appropriate approaches. This study's primary aim is to evaluate the feasibility and acceptability of delivering a brief psychological intervention to adolescents experiencing paranoia. Feasibility will assess whether the intervention can be practically delivered within a CAMHS setting, including recruitment capability, participant retention, and completion of study procedures. Acceptability will examine whether young people find the intervention suitable. Secondary aims include exploring preliminary clinical outcomes. We will examine changes in paranoia symptoms, self and other beliefs, mental imagery, valued action and day-to-day functioning. This study employs a single-case experimental design (SCED) with multiple baseline lengths (2, 3 and 4 weeks). After screening for eligibility and completing pre-intervention questionnaires, participants begin a randomly assigned baseline phase to establish stable symptom measurement. Participants then receive six weekly one-hour individual therapy sessions. Outcome measures are completed throughout the intervention to track changes. One month post-intervention, participants complete a follow-up assessment with the same outcome measures to evaluate maintenance of treatment effects and provide further feedback on their experience. This feasibility trial addresses a critical treatment gap for adolescent paranoia. If successful, findings could guide the development of larger definitive trials. Positive findings could contribute to the development of evidence-based interventions for young people experiencing paranoia in routine mental health services.

There are multiple ways to join the present study. Healthcare workers at different institutions across Germany identify eligible participants and invite them to participate in the study. Those institutions include inpatient wards and outpatient facilities. Moreover, participants can join via multiple channels, including online channels and advertising such as social media, etc. Eligibility screenings and baseline clinician ratings are conducted centrally by research associates (psychologists) at Charité Universitätsmedizin Berlin via a video interview. After confirming the inclusion criteria, participants will be randomised and receive the self-report section of the baseline assessment. Randomization is conducted independently by research associates at the Universitätsklinikum Hamburg-Eppendorf in Hamburg. After 12 weeks, participants complete a clinical interview to assess the rater-based section of the post-treatment assessment and receive the self-report section via email. All participant data is stored in a pseudonymized format. No clinical data is saved in combination with clinical data. The participants have the right to access their data and the right to claim deletion of their data. Data are stored in an online database, accessible only to researchers involved in the study. Due to the exploratory nature of this study, we aim to recruit 60 to 80 participants in total until June.

This project is aimed at advancing neuropsychological diagnostics, enriching and modernizing the panorama of both clinical and forensic psychometric testing. The rapid socio-demographic changes, the developments of neuropsychological semiotics and nosography, as well as the growing applicative specialization of neuropsychological assessment make it necessary to introduce further tools to satisfy the diagnostic requests in clinical contexts and more recently in the forensic field (i.e., tests to be administered remotely; bedside screeners; domain-specific in-depth tests; tools for assessing testamentary capacity). Specifically, the present study aims to: a) develop, calibrate and evaluate the psychometric properties of I and II level clinical and/or forensic neuropsychological tests evaluating instrumental and non-instrumental functions in a sample of neurologically healthy individuals representative of the Italian population ; b) evaluate the cross-sectional and longitudinal clinical usability of the aforementioned tests in clinical samples (patients with neurological and neuropsychiatric pathologies of different etiology).
