Range adaptive value representations in schizophrenia and major depression.

Anhedonia and amotivation are core symptoms of schizophrenia (SCZ) and major depressive disorder (MDD). Reward processing involves constructing and contrasting the representations for expected value (EV) and outcome value (OV) of a given stimulus, a phenomenon termed range adaptation. Impaired range adaptation can lead to anhedonia and amotivation.

Psychometric Properties of the Caregiver Strain Questionnaire in a Chinese Sample of Caregivers of Children with Autism Spectrum Disorder.

The Caregiver Strain Questionnaire assesses the three dimensions of caregiver strain, namely the objective, subjective externalized and subjective internalized strain. It was validated among caregivers of children with Autism Spectrum Disorder (ASD) in the United States and Mainland China with promising psychometric properties.This study aimed to develop and validate the Chinese (traditional script) version of the Caregiver Strain Questionnaire (C-CGSQ) among 198 caregivers of children with ASD in Hong Kong.

Emotional subtypes in patients with depression: A cluster analysis.

Major depressive disorder (MDD) is associated with deficits in emotion experience, expression and regulation. Whilst emotion regulation deficits prolong MDD, emotion expression influences symptomatic presentations, and anticipatory pleasure deficits predict recurrence risk. Profiling MDD patients from an emotion componential perspective can characterize subtypes with different clinical and functional outcomes.

Latent structure of self-report negative symptoms in patients with schizophrenia: A preliminary study.

Introduction: Negative symptoms are associated with poor outcomes and functioning. Latent structure of negative symptoms is important for identifying potential intervention targets for novel treatments. Self-report instruments have been developed to measure negative symptoms.

Staging of Dementia Severity With the Hong Kong Version of the Montreal Cognitive Assessment (HK-MoCA)'s.

Background: The Hong Kong version of Montreal Cognitive Assessment (HK-MoCA) has been used to screen for dementia, but it has not been validated to delineate the stages of Alzheimer disease (AD). This study aimed to determine the cut-off score ranges for mild, moderate, and severe AD.

Methods: The HK-MoCA score was matched against the Clinical Dementia Rating on 155 patients with AD.

Clinical risk model to predict 28-day unplanned readmission via the accident and emergency department after discharge from acute psychiatric units for patients with psychotic spectrum disorders.

Background: Unplanned readmissions rates are an important indicator of the quality of care provided in a psychiatric unit. However, there is no validated risk model to predict this outcome in patients with psychotic spectrum disorders.

Aims: This paper aims to establish a clinical risk prediction model to predict 28-day unplanned readmission via the accident and emergency department after discharge from acute psychiatric units for patients with psychotic spectrum disorders.

Meta-analysis of neuropsychological measures of executive functioning in children and adolescents with high-functioning autism spectrum disorder.

Existing literature on the profile of executive dysfunction in autism spectrum disorder showed inconsistent results. Age, comorbid attention-deficit/hyperactivity disorder (ADHD) and cognitive abilities appeared to play a role in confounding the picture. Previous meta-analyses have focused on a few components of executive functions.
