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).

Comorbid anxiety, loneliness, and chronic pain as predictors of intervention outcomes for subclinical depressive symptoms in older adults: evidence from a large community-based study in Hong Kong.

Background: Depression is among the leading causes of the global burden of disease and is associated with substantial morbidity in old age. The importance of providing timely intervention, particularly those with subclinical symptoms, has thus increasingly been emphasised. Despite their overall effectiveness, a small but notable subgroup tends to be less responsive to interventions.

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.

Comparison of networks of loneliness, depressive symptoms, and anxiety symptoms in at-risk community-dwelling older adults before and during COVID-19.

Network analysis provides an innovative approach to examining symptom-to-symptom interactions in mental health, and adverse external conditions may change the network structures. This study compared the networks of common risk factors and mental health problems (loneliness, depressive symptoms, and anxiety symptoms) in community-dwelling older people before and during COVID-19. Older adults (aged ≥ 60) at risk for depression were recruited through non-governmental organizations.

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.

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.

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.

The emergence of primary negative symptoms: relevance of timing?

Negative symptoms are an important symptom dimension in schizophrenia that are often least responsive to antipsychotic medications. We revisit the current practice of identifying 'primary' negative symptoms and suggest that its concept would benefit from a further elaboration of their timing of emergence in relation to the dynamic neurobiological changes to enhance their utility in clinical decision-making and research.

The Hong Kong youth epidemiological study of mental health (HK-YES)-A population-based psychiatric epidemiology study of youth mental health in Hong Kong: A study protocol.

Aim: Young people in Hong Kong have been facing numerous population-level events over the past year, including social unrest and the COVID-19 pandemic. Representative data concerning the mental health of youths, however, is limited. The Hong Kong Youth Epidemiological Study of Mental Health (HK-YES) is commissioned to provide the first representative prevalence estimates and correlates of mental disorders among young people in Hong Kong.

Assessing anxiety among adolescents in Hong Kong: psychometric properties and validity of the Generalised Anxiety Disorder-7 (GAD-7) in an epidemiological community sample.

Background: The development of a valid and simple-to-use self-administered tool in Asian adolescents for clinical screening and intervention remains limited. The present study assessed the psychometric characteristics and validity of the Generalised Anxiety Disorder Scale-7 (GAD-7) among adolescents in Hong Kong.

Methods: Epidemiological data from 3,261 Hong Kong adolescents aged 15 - 24 years were analysed for the construct validity, criterion validity, concurrent validity, and Rasch Model.

Social context and loneliness in an epidemiological youth sample using the Experience Sampling Method.

Background: Previous research has shown the relationship between loneliness and affect, as well as the relationship between trait loneliness and state loneliness. However, none has investigated how social context affects the association between loneliness and affect. The current study aims to examine the association between trait loneliness, state loneliness and momentary affects in different social contexts.

Visual-stress-related cortical excitability as a prospective marker for symptoms of depression and anxiety in young people.

Visual stress is thought to reflect cortical excitability and has been associated with many neurological, neuropsychiatric, and neurodevelopmental conditions. However, its relationships with symptoms of depression and anxiety have not yet been elucidated. We conducted two separate studies to first examine visual stress in a longitudinal community sample of 104 participants (aged 12-24) in association with prospective symptoms of depression, anxiety, and distress after 3 months, and subsequently in a cross-sectional epidemiological sample of 530 participants (aged 15-24) to validate its associations with current mood and distress symptoms.

Stressful events as correlates of depressive and PTSD symptoms in Hong Kong women during social unrest and COVID-19 pandemic.

Background: Stressors at the population level affect women more than men. The influence of prolonged stressors on mental disorders in women is yet unknown, especially when social movements and pandemics coexist.

Methods: This study analysed data from an online mental health self-help service for women in Hong Kong between May and September 2020.
