Changes in body mass index and its association with socio-demographic characteristics between 2010 and 2016 in Singapore

A qualitative study was conducted among fifteen psychotherapy recipients se…
How do professionals and non-professionals respond to non-suicidal self-injury? Lived experiences of psychiatric outpatients in Singapore
Our findings provide a better understanding of responses to NSSI that are considered helpful and unhelpful, and can be used to improve existing guidelines on responding to NSSI
Alcohol’s Harm to Others: Victim Data on Prevalence and Risk Factors in a Nationwide Population Survey
Alcohol’s harm to others (AHTO) is a growing concern globally. Yet research in Asia, especially among multi-ethnic populations, remains scarce. This cross-sectional study utilized national population data from the Health and Lifestyle Survey, and aimed to assess the prevalence and risk factors associated with AHTO in Singapore. Among 6465 respondents, findings revealed a lower prevalence of reported harm from others’ drinking (9.6%) compared to W…

Positive mental health in psychotherapy: A qualitative study from psychotherapists’ perspectives
PMH in psychotherapy is a multidimensional concept that means more than symptom management and distress reduction in clients. There is potential value for its application in psychotherapy practice, though some concerns need to be addressed before it can be well integrated
Differences in the Prevalence and Profile of DSM-IV and DSM-5 Alcohol Use Disorders—Results from the Singapore Mental Health Study 2016
While using the DSM-5 criteria would result in a lower prevalence of AUD in Singapore, it remains a highly comorbid condition associated with a poor health-related quality of life that is largely untreated, which makes it a significant public health concern
The Relationship of Socioeconomic Status to Alcohol, Smoking, and Health: A Population-Level Study of the Multiethnic Population in Singapore
This study aimed to (a) describe the differences in the prevalence of alcohol use disorder (AUD), smoking, nicotine dependence (ND), and health conditions (physical and mental) across socioeconomic status (SES); (b) study the differences in alcohol-related characteristics (e.g., frequency, quantity); and (c) assess the association between SES with health behaviors (alcohol use, smoking) and health status. This cross-sectional study recruited part…
Gender Differences in Alcohol Use: A Nationwide Study in a Multiethnic Population
The increase in alcohol consumption, and the greater consequences of chronic alcohol use among females, as well as the convergence of the gender gap warrants investigation. This paper aims to uncover gender differences in individuals with alcohol use disorder (AUD) in Singapore. The SMHS 2016 was a population-based, cross-sectional, epidemiological study. Recruitment spanned from August 2016 to March 2018, where 6126 respondents were recruited. S…

Introduction: The current study aimed to establish the lifetime prevalence of schizophrenia and other psychotic disorders, its sociodemographic correlates and association with physical disorders using data from the Singapore Mental Health Study (SMHS 2016). Methods: A two-phase design comprising population-level screening of psychotic symptoms using the World Health Organization Composite International Diagnostic Interview version 3.0 psychosis s…
Development of the Chinese, Malay and Tamil translations of the Positive Mental Health Instrument: Cross-cultural adaptation, validity and internal consistency
This study describes the development and validation of Chinese, Malay and Tamil translations of the Positive Mental Health Instrument (PMHI) in a general population sample in Singapore. Translations were performed using two independent forward translations followed by expert panel discussions and tested for content, construct and language appropriateness using focus group discussions. The final translated tools were field-tested among 220 residen…
An Exploration of Differences Between Deliberate Self-Harm with and without Suicidal Intent Amongst a Clinical Sample of Young People in Singapore: A Cross-Sectional Study
This study examined differences between young people with mental illness who engage in deliberate self-harm with and without suicidal intent, as well as socio-demographic and clinical factors that are related to the increased likelihood of suicide attempt amongst self-harming young people. A total of 235 outpatients with mental illness who had engaged in deliberate self-harm were recruited from a tertiary psychiatric hospital in Singapore. Partic…
Development and validation of the Rapid Positive Mental Health Instrument (R-PMHI) for measuring mental health outcomes in the population
The unidimensional 6-item R-PMHI offers brevity over the original multidimensional measure while appropriately representing the positive mental health construct. Prospective studies are needed to assess its responsiveness and test-retest reliability
Happiness and Cognitive Impairment Among Older Adults: Investigating the Mediational Roles of Disability, Depression, Social Contact Frequency, and Loneliness
Background: Understanding the lower level of happiness among older adults with cognitive impairment has been a largely neglected issue. This study (1) reports on the level of happiness among older adults in Singapore and (2) examines the potential mediating roles of depression, disability, social contact frequency, and loneliness in the relationship between cognitive scores and happiness. Methods: Data for this study were extracted from the Well-…
Smoking and Socio-demographic correlates of BMI
The study identified certain subgroups and risk factors that are associated with obesity. There is a need for further research to explore and identify genetic, metabolic and ethnic differences that underlie the interaction between ethnicity and smoking status which affects BMI
