Eye Movement Abnormalities During the Gaze Perception Task in Individuals With Clinical High Risk for Psychosis: A Discriminant Analysis With Hidden Markov Models.

Objectives: Social cognitive impairments were well-documented in schizophrenia and individuals with clinical high risk for psychosis (CHR). While eye movement abnormalities during gaze perception in schizophrenia have been suggested, such understanding in individuals with CHR is limited.

Design, Settings And Participants: This study recruited 36 CHR individuals and 50 healthy controls (HC) to perform a gaze perception task with eye-tracking techniques analyzed with hidden Markov models for predictability and pattern recognition.

Can headwind, an online clinician-led mental health advisory platform, improve the engagement of distressed young people in community services? A multicohort analysis.

Objective: The study evaluated the effectiveness of service, an online, clinician-led mental health advisory platform, in engaging individuals with moderate to severe psychological distress. It also compared distress reduction achieved through with natural recovery in a community cohort, providing a benchmark for evaluating active interventions.

Design Setting And Participants: The study analysed data from 13 527 people across three cohorts: users (n=3559), participants in a territory-wide youth mental health (YMH) programme (n=6734) and a community youth cohort (n=3234).

Breakfast skipping and depressive symptoms in an epidemiological youth sample in Hong Kong: the mediating role of reduced attentional control.

Introduction: Breakfast skipping is common among young people, although previous work has suggested its negative influences on cognitive and executive functions and mental health outcomes. Whether reduced impulse control, particularly in the cognitive domain, would be a mechanism that links breakfast skipping to elevated psychiatric symptoms remains to be investigated.

Methods: We used data from 3154 young people (aged 15-25 years) in the Hong Kong Youth Epidemiological Study of Mental Health 2019-2022.

The electroencephalography protocol for the Accelerating Medicines Partnership® Schizophrenia Program: Reliability and stability of measures.

Individuals at clinical high risk for psychosis (CHR) have variable clinical outcomes and low conversion rates, limiting development of novel and personalized treatments. Moreover, given risks of antipsychotic drugs, safer effective medications for CHR individuals are needed. The Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ) Program was launched to address this need.

Spurious autobiographical memories of psychosis: a dopamine-gated neuroplasticity account for relapse and treatment-resistant psychosis.

Psychotic disorders are known to be associated with elevated dopamine synthesis; yet, nondopamine factors may underlie the manifestation of some psychotic symptoms that are nonresponsive to dopamine-blocking agents. One under-explored nondopamine mechanism is neuroplasticity. We propose an account of the course of psychotic symptoms based on the extensive evidence for dopamine facilitation of Hebbian synaptic plasticity in cortical and subcortical memory systems.

Exploring the Differentiation of Self-Concepts in the Physical and Virtual Worlds Using Euclidean Distance Analysis and Its Relationship With Digitalization and Mental Health Among Young People: Cross-Sectional Study.

Background: Increasing observation and evidence suggest that the process of digitalization could have profound impact to the development of human mind and self, with potential mental health consequences. Self-differentiation is important in human identity and self-concept formation, which is believed to be involved in the process of digitalization.

Objective: This study aimed to investigate the relationship between digitalization and personal attributes in the actual selves in the physical and virtual worlds.

Can a brief guided nature walk reduce distress and improve resilience, mindful attention, and sleep quality? Evidence from a pilot study with two-week follow-up.

Despite trends of deteriorating mental health globally, help-seeking remains suboptimal. Identifying less stigmatising, low-cost, and scalable approaches to mental health care is critical. We investigated the acceptability and psychological benefits of a 30-minute guided nature walk programme in an accessible country park in Hong Kong among 100 community members.

Low-Intensity Online Intervention for Mental Distress Among Help-Seeking Young People in Hong Kong: A Randomized Clinical Trial.

Importance: Mental health issues among young people are increasingly concerning. Conventional psychological interventions face challenges, including limited staffing, time commitment, and low completion rates.

Objective: To evaluate the effect of a low-intensity online intervention on young people in Hong Kong experiencing moderate or greater mental distress.

Effects of mindfulness-based intervention in preventing relapse in patients with remitted psychosis: a randomized controlled trial.

Stress is a key factor in psychotic relapse, and mindfulness offers stress resilience and well-being benefits. This study examined the effects of mindfulness-based intervention for psychosis (MBI-p) in preventing relapse at 1 year among patients with remitted psychosis in Hong Kong. MBI-p is a newly developed manual-based mindfulness protocol and was tested to have improved well-being and clinical outcomes in a pilot study with remitted psychosis patients.

Reducing mental health distress and preventing depression in young people in the community: A multimethod observational study with a real-world and prospective 12-month controlled approach: mental health distress in community youths.

Community-based youth mental health (YMH) platforms are challenging to evaluate. Using a multi-method approach, we examined the efficacy of an integrated YMH program in Hong Kong. The real-world outcomes of 1047 participants were compared with a propensity score (PS) matched control group randomly selected from the community (study 1).

Psychometric properties of the variants of the Chinese UCLA Loneliness Scales and their associations with mental health in adolescents.

Loneliness is a pervasive and distressing emotional experience that affects individuals of all ages and can have significant consequences for both physical and mental health. The UCLA Loneliness Scale (UCLA-LS) is widely used to assess the subjective feelings of loneliness, but concerns have been raised about its structure and applicability in diverse cultural contexts. This study analysed the reliability and validity of the five Chinese versions of the UCLA-LS in a representative sample of 2,643 adolescents and young adults with Chinese as their first language in Hong Kong.

Mentalizing impairments and hypermentalizing bias in individuals with first-episode schizophrenia-spectrum disorder and at-risk mental state: the differential roles of neurocognition and social anxiety.

Mentalizing, or theory of mind (ToM), impairments and self-referential hypermentalizing bias are well-evident in schizophrenia. However, findings compared to individuals with at-risk mental states (ARMS) are inconsistent, and investigations into the relationship between social cognitive impairments and social anxiety in the two populations are scarce. This study aimed to examine and compare these deficits in first-episode schizophrenia-spectrum disorder (FES) and ARMS, and to explore potential specific associations with neurocognition and symptomatology.

Modeling the effects of treatment resistance and anticholinergic burden on cognitive function domains in patients with schizophrenia.

The contribution of anticholinergic burden to cognitive function in patients with treatment resistant schizophrenia (TRS) is uncertain. This case-control study aims to comprehensively examine the association between treatment resistance and cognitive functions and the contribution of anticholinergic burden in patients with schizophrenia. Anticholinergic burden of all patients was calculated using the Anticholinergic Cognitive Burden scale.

Aberrant connectivity in the hippocampus, bilateral insula and temporal poles precedes treatment resistance in first-episode psychosis: a prospective resting-state functional magnetic resonance imaging study with connectivity concordance mapping.

Functional connectivity resting-state functional magnetic resonance imaging has been proposed to predict antipsychotic treatment response in schizophrenia. However, only a few prospective studies have examined baseline resting-state functional magnetic resonance imaging data in drug-naïve first-episode schizophrenia patients with regard to subsequent treatment response. Data-driven approaches to conceptualize and measure functional connectivity patterns vary broadly, and model-free, voxel-wise, whole-brain analysis techniques are scarce.

Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ): Rationale and Study Design of the Largest Global Prospective Cohort Study of Clinical High Risk for Psychosis.

This article describes the rationale, aims, and methodology of the Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ). This is the largest international collaboration to date that will develop algorithms to predict trajectories and outcomes of individuals at clinical high risk (CHR) for psychosis and to advance the development and use of novel pharmacological interventions for CHR individuals. We present a description of the participating research networks and the data processing analysis and coordination center, their processes for data harmonization across 43 sites from 13 participating countries (recruitment across North America, Australia, Europe, Asia, and South America), data flow and quality assessment processes, data analyses, and the transfer of data to the National Institute of Mental Health (NIMH) Data Archive (NDA) for use by the research community.

Development of an individualized risk calculator of treatment resistance in patients with first-episode psychosis (TRipCal) using automated machine learning: a 12-year follow-up study with clozapine prescription as a proxy indicator.

About 15-40% of patients with schizophrenia are treatment resistance (TR) and require clozapine. Identifying individuals who have higher risk of development of TR early in the course of illness is important to provide personalized intervention. A total of 1400 patients with FEP enrolled in the early intervention for psychosis service or receiving the standard psychiatric service between July 1, 1998, and June 30, 2003, for the first time were included.

Comorbidity of autism spectrum and attention deficit/hyperactivity disorder symptoms and their associations with 1-year mental health outcomes in adolescents and young adults.

Autism spectrum (ASD) and attention deficit/hyperactivity disorders (ADHD) share genetic, neurological, and behavioural features. However, related research in Asia is limited. We collected self-reported ASD and ADHD symptoms from 2186 Hong Kong adolescents and young adults aged 15-24 years, among whom, 1200 provided 1-year data on mental health-related outcomes.

Age-matched versus non-age-matched comparison of clinical and functional differences between delusional disorder and schizophrenia: a systematic review.

Background: It has been widely suggested that delusional disorder (DD) differs from schizophrenia (SZ). However, whether the two disorders are truly distinct from each other is inconclusive as an older age of onset is closely linked to a better prognosis in psychotic disorders. In order to delineate the potential influence of age on outcomes, we undertook a systematic review on the clinical and functional differences between DD and SZ in age-matched and non-age-matched cohorts.

Evaluation of a Low-Intensity Online Intervention (LiON) for Reducing Distress and Mental Health Symptoms in Young People.

Purpose: Enhancing young people's mental health is crucial given that most adult mental disorders develop before age 24 years. However, it is unclear whether low-intensity interventions delivered online can be effective. This study aimed to provide preliminary evidence on whether a low-intensity online intervention (LiON) can effectively lower young people's distress levels and mental health symptoms.

COVID-19 exposure and psychosis: A comparison of clinical, functional, and cognitive profiles in remitted patients with psychosis.

The impact of Coronavirus Disease 2019 (COVID-19) on psychiatric care in remitted patients with first-episode psychosis (FEP) remains unknown. This study compared the demographic, clinical, functional, and cognitive profiles of patients recruited before and during the pandemic. The results showed that COVID patients were significantly older, smokers, alcohol users, experienced more stressors, with better functioning than pre-COVID patients.

Functional and clinical outcomes of delusional disorder and schizophrenia patients after first episode psychosis: a 4-year follow-up study.

Background: Literature has typically associated delusional disorder with a poorer prognosis relative to schizophrenia, without considering the confounding effect of age despite the differential age of onset. This study therefore aims to investigate the diagnostic stability, clinical, functional, and neurocognitive differences of Chinese first-episode psychosis age-matched patients with delusional disorder and schizophrenia at four years.

Methods: 71 delusional disorder and 71 age-matched schizophrenia patients were followed up for four years after their initial episode.

Resilient, undercontrolled, and overcontrolled personality types in Hong Kong youths and the association with mental health outcomes.

Objective: This study aimed to investigate the relationship between RUO types and mental health in a youth sample in Hong Kong.

Background: Previous research has found that Resilient, Undercontrolled, and Overcontrolled (RUO) personality types derived from Big Five personality traits are associated with mental health outcomes. Most studies, however, have predominantly been conducted in Western societies.

Effects of a culturally adapted counselling service for low-income ethnic minorities experiencing mental distress: a pragmatic randomised clinical trial.

Background: Culturally competent early mental health interventions for ethnic minorities (EMs) with no formal diagnoses are needed.

Objectives: To determine whether 8-12 weeks culturally adapted counselling (CAC) is better than waiting (waitlist (WL) group) to reduce depressive and anxiety symptoms and stress levels among EMs with elevated mental distress.

Methods: Hong Kong EMs with mild and above-mild mental distress were randomly assigned to CAC or WL in this pragmatic, randomised, WL-controlled trial.
