Equipercentile linking of the Sheehan Disability Scale and the World Health Organization Assessment Schedule 2.0 scales in people with mental disorders

BACKGROUND

The Sheehan Disability Scale (SDS) and the World Health Organization Disability Assessment Scale (WHODAS 2.0) have been widely used to measure functional impairment and disability. To ensure that the scores from these two scales are practically exchangeable across diseases, therapies, and care programmes, the current study aimed to examine the linkage of the WHODAS 2.0 with the SDS and develop a simple and reliable conversion table for the two scales in people with mental disorders.

METHODS

A total of 798 patients (mean age = 36.1, SD = 12.7) were recruited from outpatient clinics of the Institute of Mental Health, and the Community Wellness Clinic in Singapore. Using a single-group design, an equipercentile equating method with log-linear smoothing was used to establish a conversion table from the SDS to the WHODAS 2.0 and vice versa.

RESULTS

The conversion table showed that the scores were consistent for the entire range of scores when the scores were converted either from the SDS to the WHODAS 2.0 or from the WHODAS 2.0 to the SDS. The agreement between the WHODAS 2.0's raw and converted scores and SDS's raw and converted scores were interpreted as good with intraclass correlation coefficient of 0.711 and 0.725, respectively.

CONCLUSION

This study presents a simple and reliable method for converting the SDS scores to the WHODAS 2.0 scores and vice versa, enabling interchangeable use of data across these two disability measures.

Barriers to using eHealth/mHealth platforms and perceived beneficial eHealth/mHealth platform features among informal carers of persons living with dementia: a qualitative study

BACKGROUND

New technologies have brought about a new age of technology-enabled aids that can equip informal carers with the relevant resources for better care. These include but are not limited to facilitating access to healthcare providers, knowledge of caring for persons living with dementia, and sources of support for carers' well-being. This qualitative study explores barriers to using eHealth/mHealth platforms and perceived beneficial eHealth/mHealth platform features among informal carers of persons living with dementia.

METHODS

An exploratory qualitative study design was employed. Semi-structured interviews were conducted among 29 informal carers of persons living with dementia in Singapore recruited via convenience and snowball sampling. The interviews were audio-recorded and transcribed verbatim. Thematic analysis was used to analyse the data.

RESULTS

The participants in this study identified several barriers to using eHealth/mHealth platforms, including personal preference, apprehension, poor user experience and lack of skills. On the other hand, knowledge of dementia, caring for persons living with dementia and self-care, a list of resources, social support, location monitoring and alert systems, and the ability to manage appointments and transactions were valuable features for eHealth/mHealth platforms.

CONCLUSIONS

Despite the underutilisation of eHealth/mHealth platforms, carers expressed a keen interest in using them if they are functional and capable of reducing their care burden. The findings from this study can contribute to developing content and features for eHealth/mHealth interventions aimed at lightening carers' burden in their day-to-day caring routine.

Validation of the 12-item World Health Organization Disability Assessment Schedule 2.0 in individuals with schizophrenia, depression, anxiety, and diabetes in Singapore

BACKGROUND

There is limited evidence on the reliability and validity of the 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) in an Asian patient population with mental and physical disorders. The current study aimed to examine the psychometric properties of the WHODAS 2.0 among patients with schizophrenia, depression, anxiety, and diabetes.

METHODS

A total of 1076 patients (M  =  40.9 years, SD  =  14.7) were recruited from the outpatient clinics of a tertiary psychiatric hospital and a primary care clinic. Internal consistency and test-retest reliability, structural validity, convergent validity, agreement, and floor and ceiling effects were examined.

RESULTS

Our confirmatory factor analysis (CFA) showed that the 1-factor model fits our data. Multigroup CFA demonstrated metric and scalar invariance, indicating the scores can be compared across the four conditions. The WHODAS 2.0 scale had excellent reliability in the overall sample and good to excellent reliability across conditions. The test-retest reliability and agreement between self-administered and interviewer-administered modes were good. The WHODAS 2.0 scores had moderate to strong correlations with the Social and Occupational Functioning Scale and the Sheehan Disability Scale scores in the overall sample and across four conditions.

CONCLUSION

Findings suggest that the WHODAS 2.0 is a valid tool to measure functioning and disability in those with schizophrenia, anxiety, depression, and diabetes in an Asian patient population.

Mediating effect of symptom severity on the relationship between aggression, impulsivity and quality of life outcomes among patients with schizophrenia and related psychoses

Aims

Aggression and impulsivity among individuals with schizophrenia have been associated with poor clinical outcomes including worsening of symptoms and substance abuse which have been linked to a lower quality of life (QoL). The current study aimed to look at the mediating effect of symptom severity on the relationship between aggression, impulsivity and QoL among outpatients with schizophrenia and related psychoses in a multi-ethnic Asian population.

Methods

Data (n = 397) were collected from outpatients seeking treatment at the Institute of Mental Health. The World Health Organization quality of life-BREF (WHOQOL-BREF) scale, the symptoms checklist-90 revised (SCL-90-R), Buss Perry aggression questionnaire (BPAQ), and the Barratt impulsiveness scales (BIS) were used to assess subjective well-being, symptom severity, aggression, and impulsivity, respectively. Mediation analysis was performed using the PROCESS macro to understand the mediating effect of symptom severity.

Results

Motor impulsivity (MI) was indirectly associated with both the physical and psychological health domains of QoL while self-control was indirectly associated with the physical, psychological, and environmental health QoL domains through increased symptom severity.

Conclusion

The significant indirect effect of symptom severity in our study highlights one potential pathway through which impulsivity impacts the QoL of individuals with schizophrenia and related psychoses. Elucidating other factors besides symptom severity that have an indirect effect on the QoL of individuals provides alternative approaches for treatment through which better clinical outcomes can be achieved.

Exploring views and experiences of the general public's adoption of digital technologies for healthy lifestyle in Singapore: a qualitative study

Objective

Little is known about the general adult population's adoption of digital technology to support healthy lifestyle, especially when they are expected to take greater personal responsibility for managing their health and well-being today. The current qualitative study intended to gain an in-depth understanding of determinants of digital technology adoption for healthy lifestyle among community-dwelling adults in Singapore.

Design

A qualitative study design, with thematic framework analysis was applied to develop themes from the data.

Setting

Semi-structured individual interviews were conducted with participants either face-to-face or online through a videoconferencing platform.

Participants

14 women and 16 men from the general population who were between the ages of 22 and 71 years.

Results

Three major themes were developed: (1) digitally disempowered (2) safety and perceived risks and harm; (3) cultural values and drives. Adoption of technology among the general population is needs-driven, and contingent on individual, technological and other cross-cultural contextual factors.

Conclusion

Our findings highlight there is no one solution which fits all individuals, emphasizing the challenges of catering to diverse groups to reduce barriers to adoption of digital technologies for healthy lifestyle. Digital guidance and training, as well as social influences, can motivate technological adoption in the population. However, technical problems as well as data security and privacy concerns should first be adequately addressed. This study provides rich cross-cultural insights and informs policy-making due to its alignment with government public health initiatives to promote healthy lifestyle.

Prevalence and correlates of suicide planning and attempt among individuals with suicidal ideation: Results from a nationwide cross-sectional survey

BACKGROUND

Suicidality spans from having suicidal ideation to planning and making an attempt. However, not all individuals with suicidal thoughts will proceed to plan or attempt suicide. Our study investigated (i) the prevalence of suicide planning and attempt among those with suicidal ideation and (ii) their associations with sociodemographic characteristics, mental disorders, adverse childhood events and prior suicidal behaviour.

METHOD

This cross-sectional analysis utilised data from Singapore Mental Health Study 2016. Only respondents with suicidal ideation were included. A total of 411 and 365 individuals were examined to establish the prevalence of suicide planning and attempt respectively. Multivariable logistic regressions were performed to determine associations.

RESULTS

The prevalence of suicide planning and attempt were 17.7 % and 10.6 % respectively, with >80.0 % occurring within a year of suicidal ideation. Suicide planning was more likely among those who had mood disorders. Suicide attempt was more likely for those were currently married, had lower educational qualifications, history of anxiety disorders, history of emotional neglect and parental separation.

LIMITATIONS

Recall bias may be present because the age of onset for various mental disorders and suicidal behaviours were self-reported. As suicide was criminalised when the study was conducted, the prevalence of suicidal behaviours may have been underestimated.

CONCLUSION

Individuals at risk of suicide planning and attempt should be identified early since most of them progressed within a year. Findings suggest the importance of including prior suicide behaviour and history of dysfunctional family and emotional abuse in suicide risk assessment and intervention.

Measuring social desirability bias in a multi-ethnic cohort sample: its relationship with self-reported physical activity, dietary habits, and factor structure

BACKGROUND

Social desirability bias is one of the oldest forms of response bias studied in social sciences. While individuals may feel the need to fake good or bad answers in response to sensitive or intrusive questions, it remains unclear how rampant such a bias is in epidemiological research pertaining to self-reported lifestyle indicators in a multicultural Asian context. The main purpose of the current study is, therefore, to examine the sociodemographic correlates and impact of social desirability responding on self-reported physical activity and dietary habits at an epidemiological scale in a non-western multi-cultural Asian setting.

METHODS

Prior to the main analyses, confirmatory and exploratory factor analyses were conducted to determine the factorial validity of a western derived concept of social desirability. Multiple regression analyses were conducted on cross-sectional data (n = 2995) extracted from a nationwide survey conducted between 2019 and 2020.

RESULTS

A unique factor structure of social desirability was found and was therefore used for subsequent analyses. Multiple regression analyses revealed older age groups, the Indian ethnic group, those with past or present marriages, and having no income, had a significantly greater tendency to act on the bias.

CONCLUSION

The construct of social desirability bias was fundamentally different in a multicultural context than previously understood. Only a small proportion of variance of self-report lifestyle scores was explained by social desirability, thus providing support for data integrity.

Positive aspects of caregiving among informal caregivers of persons with dementia in the Asian context: a qualitative study

BACKGROUND

Positive aspects of caregiving are important coping resources for informal caregivers of persons with dementia (PWD). However, existing studies mostly focused on caregivers from western societies and less attention was paid to the potential cultural differences. This study aims to explore positive aspects of caregiving in the Asian context.

METHODS

A qualitative methodology with semi-structured interviews was adopted. A total of 29 informal caregivers of PWD in Singapore were interviewed from Apr 2019 to Dec 2020. All the interviews were audio-recorded and transcribed verbatim for the analysis. Inductive thematic analysis was conducted.

RESULTS

The results revealed a total of three major themes with 11 sub-themes including: 1) positive aspects within self (i.e., better understanding of dementia and caregiving, personal growth, role satisfaction, and improved awareness of self-care); 2) positive aspects between caregiver and PWD (i.e., chance to demonstrate filial piety towards PWD, happiness and positive attitudes of PWD, positive interactions with PWD, and closer relationships with PWD); and 3) positive aspects between caregiver and others (i.e., empathy towards other caregivers, befriending peers, and sharing dementia and caregiving knowledge with others).

DISCUSSION

Findings from this study improved our understanding on positive aspects of caregiving among informal caregivers of PWD in the Asian context. In addition to similar themes across cultures such as personal growth, our study identified a few unique themes like improved awareness of self-care and chances to demonstrate filial piety. For future studies targeting Asian caregivers, it is necessary to include these cultural-specific positive aspects of caregiving.

Differences in the Prevalence and Profile of DSM-IV and DSM-5 Alcohol Use Disorders-Results from the Singapore Mental Health Study 2016

INTRODUCTION

The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) criteria for alcohol use disorders (AUD) was a significant shift from the historical DSM-IV Text Revised version. Following this shift in diagnostic criteria, a difference in the prevalence of AUD was expected. The current study aimed to evaluate the consequences of the modification of the diagnostic criteria from DSM-IV to DSM-5 AUD using lifetime diagnosis in Singapore's multi-ethnic population using data from a nationwide epidemiological study.

METHODS

Respondents were assessed for lifetime mental disorders using the Composite International Diagnostic Interview (CIDI) administered through face-to-face interviews. Lifetime DSM-IV AUD diagnoses were compared with DSM-5 AUD diagnoses generated by modifying the criteria and the addition of the craving criterion. Sociodemographic correlates of lifetime DSM-IV/DSM-5 AUD were examined using multiple logistic regression analysis. Associations between DSM-IV/DSM-5 AUD, chronic conditions, and the HRQOL summary scores were examined using logistic and linear regression after controlling for significant sociodemographic factors.

RESULTS

The lifetime prevalence of DSM-IV AUD was 4.6% (0.5% for dependence and 4.1% for abuse) in the adult population, while the lifetime prevalence of DSM-5 AUD was 2.2%. Younger age, male gender, and lower education were associated with higher odds of both DSM-IV and DSM-5 AUD. However, those who were economically inactive (versus employed) (AOR, 0.4; 95% CI 0.2-0.9) and had a higher monthly household income (SGD 4000-5999 versus below SGD 2000) had lower odds of DSM-IV AUD (AOR, 0.4; 95% CI 0.2-0.7), but this was not observed among those with DSM-5 AUD. Both DSM-IV and DSM-5 AUD were associated with significant comorbidities in terms of other mental disorders; however, those diagnosed with lifetime GAD had significantly higher odds of having DSM-5 AUD (AOR, 5; 95% CI 1.9-13.2) but not DSM-IV AUD.

CONCLUSIONS

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.

Barriers and facilitators for adopting a healthy lifestyle in a multi-ethnic population: A qualitative study

A healthy lifestyle is defined as ‘a way of living that lowers the risk of being seriously ill or dying early.’ Although barriers and facilitators of healthy lifestyles have been well-studied among populations like those with chronic non-communicable diseases, adolescents, and older adults in Asia, less information is available on barriers and facilitators perceived by the general adult population. Using a qualitative methodology and leveraging the socio-ecological model, the current study aimed to understand the barriers and facilitators of a healthy lifestyle in a sample of Singapore residents. Overall, 30 semi-structured interviews were conducted in English and other local languages from August 2020 to March 2021. Transcripts were analysed using framework analysis. Five main themes pertaining to personal, interpersonal, environmental, socio-cultural, and policy-level factors were classified under the two overarching categories of barriers and facilitators of healthy lifestyles. The results of this study offer important insights into understanding the barriers and facilitators to the adoption of a healthy lifestyle among people in Singapore. Furthermore, our findings illustrate the complex interplay between individuals, social relationships, environment, and policy that can act as either a barrier or a facilitator to adopting a healthy lifestyle.

Religiosity, Religious Coping and Distress Among Outpatients with Psychosis in Singapore

This study aimed to investigate the prevalence of religious coping and explore the association between religious coping, religiosity, and distress symptoms amongst 364 outpatients diagnosed with psychosis in Singapore. Positive and Negative Religious Coping (PRC and NRC), religiosity (measuring the constructs of Organised Religious Activity (ORA), Non-Organised Religious Activity (NORA), and Intrinsic Religiosity (IR)) and severity of distress symptoms (depression, anxiety and stress) were self-reported by the participants. The majority of participants (68.9%) reported religion to be important in coping with their illness. Additionally, multiple linear regression analyses found that NRC was significantly associated with higher symptoms of distress. In contrast, ORA was significantly associated with lower anxiety symptom scores. Overall, the study indicates the importance of religion in coping with psychosis and the potential value in incorporating religious interventions in mental health care.

Factors influencing uptake of diabetes health screening: a mixed methods study in Asian population

BACKGROUND

Health screens are the cornerstones for health promotion and preventive interventions at a community level. This study investigated the barriers and facilitators to the uptake of diabetes health screening in the general population of Singapore.

METHODS

In this mixed methods study, participants without diabetes were recruited from the general population. The quantitative phase (n = 2459) included face to face survey of participants selected through disproportionate stratified random sampling. Those who participated in the quantitative survey were then randomly chosen for a one-to-one semi-structured interview (n = 30).

RESULTS

Among the survey respondents, 73.09% (n = 1777) had attended a diabetes health screening in their lifetime whilst 42.36% (n = 1090) and 57.64% (n = 1328, p < 0.0001) attended the health screens regularly (every 12 months) and irregularly, respectively. A significantly higher proportion of older adults (≥ 40 years) attended regular diabetes health screening compared to younger adults (less than 40 years; 55.59% vs 24.90%, p < 0.001). The top 3 reasons for attending regular health screens were to detect diabetes early, to make lifestyle changes in case of a diagnosis and being health conscious. Qualitative interviews identified similar issues and complex nuances that influenced the uptake of regular diabetes health screening. Several personal factors (laziness, self-reliance, psychological factors, etc.), competing priorities, fatalistic beliefs, affordability, misconceptions about the screens, and appointment related factors (inconvenient location, time, etc.) were identified as barriers, while affordable screens, sense of personal responsibility, perception of susceptibility /risk, role of healthcare team (e.g. reminders and prescheduled appointments) and personal factors (e.g. age, family, etc.) were facilitators. Age, household income, ethnicity and educational level were associated with the uptake of regular diabetes health screening.

CONCLUSION

The uptake of regular diabetes health screening can be improved. Several barriers and enablers to the uptake of diabetes health screening were identified which should be addressed by the policy makers to alleviate misconceptions and create greater awareness of the importance of the programme that will improve participation.

The impact of having foreign domestic workers on informal caregivers of persons with dementia - findings from a multi-method research in Singapore

Background

Informal caregivers of persons with dementia (PWDs) sometimes engage foreign domestic workers (FDWs) to support their caregiving journey. However, there has not been much research to establish if this is really beneficial. The current study aims to investigate whether engaging FDWs specifically for caregiving of PWDs truly moderates caregiver stress and to explore caregivers’ experiences of engaging FDWs.

Methods

A multi-method study design with a quantitative and qualitative sub-study was adopted. For the quantitative sub-study, 282 informal caregivers of PWDs were recruited. Propensity score matching analysis was used. For the qualitative sub-study, 15 informal caregivers with FDWs were interviewed. Inductive thematic analysis was conducted.

Results

The quantitative sub-study confirmed that engaging FDWs did moderate the depressive symptoms of informal dementia caregivers (marginal effect = -3.35, p = 0.0497). However, such support did not affect their caregiving burden, self-efficacy, and perceived positive aspects of caregiving. The qualitative sub-study suggested that engaging FDWs is an ambivalent experience, which entails both support and challenges.

Conclusions

The current study confirmed previous research findings, that engaging FDWs moderated depressive symptoms among caregivers of PWDs, and it could be through their physical support such as in daily caregiving activities. Policy-makers may consider providing more subsidies to caregivers caring for PWDs with mobility issues to hire FDWs. They may also consider providing training to FDWs on dementia caregiving skills and improving the intake of such training as this might be helpful for both FDWs and caregivers during this journey.

The factor structure of the Barratt Impulsiveness Scale (BIS-11) and correlates of impulsivity among outpatients with schizophrenia and other psychotic disorders in Singapore

BACKGROUND

Impulsivity has been linked to risky behaviours amongst patients with schizophrenia or other psychotic disorders. However, there is a dearth of studies examining impulsivity amongst this population in Singapore. Moreover, to date, scales to measure impulsivity have not been validated in this population. The present study seeks to examine the underlying factor structure of the Barratt Impulsiveness Scale (BIS-11) and explore sociodemographic and clinical correlates of impulsivity within this group.

METHODS

Confirmatory factor analyses (CFA) were conducted to test factor structures of the BIS-11 proposed in extant literature. However, due to poor fit statistics, the sample (n = 397) was split into two groups, with Exploratory Factor Analyses (EFA) conducted in the first subgroup (n = 200). The final model of the EFA was then tested within the second subgroup (n = 197) with CFA. Multivariable linear regressions were conducted to examine sociodemographic and clinical correlates of each underlying factor.

RESULTS

CFA indicated a three-factor structure amongst 16-items of the BIS-11 with acceptable fit: i) Non-planning impulsivity (5-items; α = 0.94), ii) Motor impulsiveness (6-items α = 0.84), and iii) Lack of self-control (5-items, α = 0.85). Lower education was associated with higher non-planning impulsivity. While age, ethnicity, marital status, and general psychiatric symptom severity were significant correlates of motor impulsiveness, problematic alcohol use and general psychiatric symptom severity were related to a greater lack of self-control.

CONCLUSION

Factor structures of the BIS-11 suggested by extant literature were not applicable, and we propose an alternative factor structure for BIS-11. Significant correlates of impulsivity are highlighted, and avenues for future research are suggested.

Dietary patterns of persons with chronic conditions within a multi-ethnic population: results from the nationwide Knowledge, Attitudes and Practices survey on diabetes in Singapore

Background

Chronic conditions are a leading cause of death and disability worldwide and respective data on dietary patterns remain scant. The present study aimed to investigate dietary patterns and identify sociodemographic factors associated with Dietary Approaches to Stop Hypertension (DASH) scores within a multi-ethnic population with various chronic conditions.

Methods

The present study utilised data from the 2019-2020 Knowledge, Attitudes, and Practices study on diabetes in Singapore – a nationwide survey conducted to track the knowledge, attitudes, and practices pertaining to diabetes. The study analysed data collected from a sample of 2,895 Singapore residents, with information from the sociodemographic section, DASH diet screener, and the modified version of the World Mental Health Composite International Diagnostic Interview (CIDI) version 3.0 checklist of chronic physical conditions.

Results

Respondents with no chronic condition had a mean DASH score of 18.5 (±4.6), those with one chronic condition had a mean DASH score of 19.2 (±4.8), and those with two or more chronic conditions had a mean DASH score of 19.8 (±5.2). Overall, the older age groups [35– 49 years (B = 1.78, 95% CI: 1.23 – 2.33, p <0.001), 50–64 years (B = 2.86, 95% CI: 22.24 – 3.47, p <0.001) and 65 years and above (B = 3.45, 95% CI: 2.73 – 4.17, p <0.001)], Indians (B = 2.54, 95% CI: 2.09 – 2.98, p <0.001) reported better diet quality, while males (B = -1.50, 95% CI: -1.87 – -1.14, p <0.001) reported poorer diet quality versus females.

Conclusion

Overall, respondents with two or more chronic conditions reported better quality of diet while the sociodemographic factors of age, gender and ethnicity demonstrated a consistent pattern in correlating with diet quality, consistent with the extant literature. Results provide further insights for policymakers to refine ongoing efforts in relation to healthy dietary practices for Singapore.

Mapping the steps to reach psychiatric care in Singapore: An examination of services utilized and reasons for seeking help

OBJECTIVE

The aim of this study is to shed light on the types of services utilized and map the steps taken by patients in their pathways to receiving psychiatric care in Singapore.

METHODS

Participants were outpatients who were recruited from a psychiatric tertiary hospital (n = 323). Pathways to psychiatric care form was administered to collect information on sources of care utilized, reasons for seeking help and the time point of each contact made. Pathways taken by patients to reach psychiatric care were mapped, and reasons for seeking help were reviewed and analyzed. Quantile regression was conducted to explore association between sociodemographic and clinical factors with duration between onset of problem and receiving psychiatric care.

RESULTS

The need to manage symptoms was most commonly endorsed by participants as the reason that first prompted them to seek help. Prior to receiving psychiatric care, participants on average obtained services from 1.2 other care providers and the main pathway to psychiatric services was via primary care and community services (37.2%). The median duration between onset of problem and receiving psychiatric care was 6 months, and age was found to be significantly associated with shorter median duration (β = -0.172, p = 0.009).

CONCLUSIONS

Patients often consult different care providers prior to obtaining psychiatric services and contact was made more frequently via primary care and community care providers. Findings from this study reiterate the need for engaging community partners to render timely and relevant support for individuals with mental health issues.

Asthma Prevalence and its Risk Factors Among a Multi-Ethnic Adult Population

Asthma is a substantial global health problem characterized by chronic airway inflammation, leading to intermittent symptoms. This study aims to establish the prevalence and risk factors of asthma in a multi-ethnic adult population. Data for the study were extracted from the Singapore Mental Health Study 2016, a population-based, cross-sectional, epidemiological study of Singapore residents aged 18 years and above. The data relating to asthma prevalence was captured using the modified World Mental Health Composite International Diagnostic Interview (CIDI) version 3.0 chronic conditions checklist. The prevalence of lifetime asthma in this population was 11.9% (95% CI, 10.83-13.12). Those of Malay and Indian ethnicity (versus Chinese), ex-smokers (versus never smoked) and those who were overweight and obese (versus normal weight) were more likely to be associated with asthma. Participants belonging to the age group of 35 years and above (versus 18-34 years of age), male gender (versus female) were less likely to be associated with lifetime asthma. Asthma was also more likely to be associated with bipolar disorder. Those with current asthma (ie, those who had received treatment during the past 12 months) were significantly associated with lower health-related quality of life in the physical component score (PCS) than those without asthma. The high prevalence and association with lowered health-related quality of life makes asthma a significant public health concern. Our study's findings can help create awareness and encourage integrated approaches for managing asthma in the health sector.

Health Literacy and Diabetes Knowledge: A Nationwide Survey in a Multi-Ethnic Population

Health literacy is a key determinant of the public health and health climate of the nation. This study examined the functional health literacy of the nation, factors associated with health literacy, and its relationship with diabetes recognition. This cross-sectional survey recruited participants (N = 2895) who were 18 years and above from a population registry through disproportionate stratified sampling. The Brief Health Literacy Screen and other questionnaires were administered through face-to-face interviews, in one of the four national languages (English, Chinese, Malay or Tamil). The majority (80.5%) had adequate functional health literacy and were able to recognise symptoms of diabetes correctly (83.5% overall; 83.7% and 82.2% in those with adequate and inadequate health literacy, respectively). Those with inadequate health literacy had a higher incidence of chronic conditions (p < 0.001) compared to those with adequate health literacy in bivariate analysis. The majority of the sample had sufficient levels of physical activity (83.3%), and more than half reported an unhealthy lifestyle (57.4%). Older age, Chinese ethnicity, those who were employed, with lower education (secondary or below), and were married had significantly higher odds of inadequate health literacy. Health literacy was not associated with lifestyle, physical activity, chronic conditions and diabetes recognition. Health literacy interventions should focus on the disadvantaged social groups for improving their health literacy.

Readiness and Acceptance of eHealth Services for Diabetes Care in the General Population: Cross-sectional Study

BACKGROUND

Diabetes management is a growing health care challenge worldwide. eHealth can revolutionize diabetes care, the success of which depends on end user acceptance.

OBJECTIVE

This study aims to understand the readiness and acceptance of eHealth services for diabetes care among the general population, perceived advantages and disadvantages of eHealth, and factors associated with eHealth readiness and acceptance in a multiethnic Asian country.

METHODS

In this cross-sectional epidemiological study, participants (N=2895) were selected through disproportionate stratified random sampling from a population registry. Citizens or permanent residents of Singapore aged >18 years were recruited. The data were captured through computer-assisted personal interviews. An eHealth questionnaire was administered in one of four local languages (English, Chinese, Malay, or Tamil), as preferred by the participant. Bivariate chi-square analyses were performed to compare the sociodemographic characteristics and perception of advantages and disadvantages of eHealth services between the diabetes and nondiabetes groups. Multivariable logistic regression models were used to determine factors associated with eHealth readiness and acceptance. All analyses were weighted using survey weights to account for the complex survey design.

RESULTS

The sample comprised participants with (n=436) and without (n=2459) diabetes. eHealth readiness was low, with 47.3% of the overall sample and 75.7% of the diabetes group endorsing that they were not ready for eHealth (P<.001). The most acceptable eHealth service overall was booking appointments (67.4%). There was a significantly higher preference in the diabetes group for face-to-face sessions for consultation with the clinician (nondiabetes: 83.5% vs diabetes: 92.6%; P<.001), receiving prescriptions (61.9% vs 79.3%; P<.001), referrals to other doctors (51.4% vs 72.2%; P<.001), and receiving health information (34% vs 63.4%; P<.001). The majority of both groups felt that eHealth requires users to be computer literate (90.5% vs 94.3%), does not build clinician-patient rapport compared with face-to-face sessions (77.5% vs 81%), and might not be credible (56.8% vs 64.2%; P=.03). Age (≥35 years), ethnicity (Indian), and lower education status had lower odds of eHealth readiness. Age (≥35 years), ethnicity (Indian), lower education status (primary school), BMI (being underweight), and marital status (being single) were associated with a lower likelihood of eHealth acceptance. Among only those with diabetes, a longer duration of diabetes (4-18 years), higher education (degree or above), and younger age (23-49 years) were associated with eHealth readiness, whereas younger age and income (SGD 2000-3999 [US $1481-$2961]) were associated with acceptance.

CONCLUSIONS

Overall, an unfavorable attitude toward eHealth was observed, with a significantly higher number of participants with diabetes reporting their unwillingness to use these services for their diabetes care. Sociodemographic factors associated with acceptance and readiness identified a group of people who were unlikely to accept the technology and thus need to be targeted for eHealth literacy programs to avoid health care disparity.

Occupational groups and its physical and mental health correlates: results from the Singapore Mental Health Study 2016

Purpose

The physical and mental wellbeing of an individual is impacted by the type occupation one does. This study aims to establish the prevalence of mental and physical disorders, the association of occupational groups and health-related quality of life, and the extent of work-loss and work-cut back in past 30 days among the employed in the Singapore resident population.

Methods

Data from a population-based, epidemiological survey of a representative sample of Singapore citizens and permanent residents aged 18 years and above were used. Lifetime diagnosis of select mental disorders was established using the World Health Organization’s Composite International Diagnostic Interview version 3.0 (WHO-CIDI 3.0). Data on nicotine dependence, work productivity, quality of life and socio-demographics were obtained via self-report. Ten major occupational groups based on the Singapore Standard Occupational Classification were included in the analysis.

Results

The sample comprised 4021 employed individuals who were predominantly males (54.7%) and aged 35–49 years (35.4%). ‘Service and sales workers’ (22.6%), ‘Professionals’ (17.3%) and ‘Legislators, senior officials and managers’ (16.4%) were the three largest occupational groups. Socio-demographic characteristics differed significantly (p < 0.001) across all occupational groups. Lifetime prevalence of mood disorders among the employed was 8.4% and the most prevalent physical disorder was chronic pain (18.9%). No significant differences were observed in work productivity loss across the occupational groups.

Conclusions

The disparities in the socio-demographic characteristics and prevalence of mental and physical disorders across occupational categories provide policymakers with vital information to pilot effective interventions that can improve the psychosocial and physical conditions at work.

Quality of Life and Its Associations with Religiosity and Religious Coping among Outpatients with Psychosis in Singapore

This cross-sectional study investigated the relationship of religiosity, the use of positive and negative religious coping methods, and quality of life (QOL) among 364 outpatients with psychosis in Singapore. Positive religious coping was significantly associated with better scores on physical (β = 0.51, p = 0.02) and psychological (β = 0.64, p = 0.01) QOL domains in the regression model. Negative religious coping was related to worse QOL in all four domains: physical (β = −0.44, p = 0.03), psychological (β = −0.76, p < 0.01), social (β = −0.54, p = 0.03), and environment (β = −0.65, p < 0.01). Increased participation in organizational religious activities was positively associated with higher QOL for psychological (β = 2.47, p < 0.01), social relationships (β = 2.66, p = 0.01), and environment (β = 2.09, p = 0.01) domains. Interestingly, those with no religious affiliation were found with higher scores in the QOL domain for social relationships (β = 4.59, p = 0.02). Religious coping plays an important role for the QOL of outpatients with psychosis. Greater awareness of the importance of religion in this population may improve cultural competence in treatment. Individuals with psychosis may benefit from greater community support and collaboration between clinical and religious community-based organizations to improve social integration and QOL.

Help-Seeking Patterns Among the General Population in Singapore: Results from the Singapore Mental Health Study 2016

This study aimed to establish lifetime mental health service utilisation among the general population of Singapore. The sociodemographic correlates of those seeking help from different service provider groups and changes in lifetime mental health service utilisation between 2010 and 2016 among those with mental disorders were also explored. A population-based cross-sectional epidemiological household survey of the Singapore resident population aged 18 years and above was conducted from 2016 to 2018, using the World Mental Health Composite International Diagnostic Interview (CIDI) version 3.0. Data from two cross-sectional population-based studies were used for comparison of lifetime mental health service utilisation in 2010 (n = 6616) and 2016 (n = 6126). Chi square test and multiple logistic regression were used to analyse the data. A total of 6126 respondents completed the study in 2016. Overall 9.3% of the total sample, 32.0% of those with mental disorders, and 5.7% of those not meeting criteria for mental disorders, ever sought help for their mental health issues in their lifetime, from any treatment service sectors. Several sociodemographic characteristics were found to be correlated with different service provider groups. There was no change in mental health service utilisation between 2010 and 2016 for all mental disorders included in this study, with the exception of a significant increase in help sought from professionals in social services, among those with alcohol abuse. Even though the overall help-seeking rates are low, it is encouraging that those seeking help did so from mental health professionals and professionals working in the social services.

Association of adverse childhood experiences with diabetes in adulthood: results of a cross-sectional epidemiological survey in Singapore

OBJECTIVES

Several studies have linked diabetes mellitus to adverse childhood experiences (ACEs). While a number of studies have examined the association between ACEs and diabetes in Western populations, few have done it in Asian populations. The current study aimed to examine (1) the association between ACEs and diabetes, including the association after age stratification, and (2) the association of comorbid depression, resource use and health-related quality of life (HRQoL) among those with diabetes and ACEs in Singapore.

SETTINGS

Participants were surveyed in their homes or any other preferred venue of their choice.

PARTICIPANTS

6126 individuals aged 18 years and above were randomly selected among Singapore residents.

DESIGN

Cross-sectional nationwide epidemiological study.

RESULTS

Exposure to any ACE was not associated with increased odds of diabetes; however, those who had experienced parental separation, death or divorce of a parent had higher odds of diabetes. In addition, we observed significant interaction between age and ACEs in relation to odds of diabetes. ACEs were significantly associated with higher odds of diabetes mainly in the younger age group. The prevalence of major depressive disorder was significantly higher among those with diabetes and ACEs than those with diabetes alone (3.7% and 0.3% respectively).

CONCLUSIONS

Efforts to promote regular exercise and healthy lifestyles both in the population and among those with diabetes must continue for the prevention and management of diabetes. The findings emphasise the need to create more awareness of both the prevalence and impact of ACEs among those treating chronic diseases.

Prevalence, Lifestyle Correlates, and Psychosocial Functioning Among Multi-Ethnic Older Adults with Mild Cognitive Impairment in Singapore: Preliminary Findings from a 10/66 Population Study

Asia, which has the highest increase in dementia prevalence, is unfortunately lacking recent up-to-date research, with regions of Southeast Asia being the most inadequate. Preventive approaches, such as the understanding of Mild Cognitive Impairment (MCI), are currently the most effective approach in reducing the risk or delaying the onset of dementia but are not adequately understood. Additionally, there is a paucity of research examining lifestyle and sociodemographic correlates of MCI that are relevant to the local population of Singapore. To address these gaps, this study aimed to explore: 1) the prevalence of MCI and Amnestic Mild Cognitive Impairment (aMCI), 2) the psychosocial and lifestyle correlates of MCI and aMCI. Data were drawn from the Well-being of the Singapore Elderly (WiSE) population study, which is a single-phase cross-sectional household survey conducted among older adult residents aged 60 years and above. Analyses revealed that the weighted MCI prevalence (1.2%) was lower than global figures. Few sociodemographic and lifestyle habits were related to MCI prevalence, as only age and physical activeness emerged as significant correlates. Despite the low prevalence of MCI, individuals with MCI experienced marked disability, clinical levels of depression and anxiety, which are all concerning finds. Due to the exploratory and cross-sectional nature of the study, future longitudinal research could further refine our understanding of MCI and confirm the present findings.

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 residents per language using self-administered questionnaires comprising the translated PMHI and other validity measures. Missing data, floor and ceiling effects, confirmatory factor analysis (CFA), internal consistency, item response theory differential item functioning (IRT-DIF) and criterion validity were assessed. A total of 10 PMHI-Chinese items, 26 PMHI-Malay items and six response categories and six PMHI-Tamil items were modified based on expert panel and focus group discussions. PMHI had low missing data and showed negative but acceptable skewness (<2) and kurtosis (<7) for all translations, except for the PMHI-Malay "spirituality" subscale (skewness: -2.8; kurtosis: 12.5). CFA showed that all three PMHI translations fulfilled the original six-factor-higher-order structure (RMSEA = 0.05, CFI = 0.962, TLI = 0.96). Cronbach's alpha coefficients for total PMHI were 0.958, 0.954, 0.945 and 0.949 in the overall sample and the Chinese, Malay and Tamil translations, respectively. The three translations of the PMHI showed expected and significant positive (r = 0.116 to 0.663) and negative correlations (r = -0.137 to -0.574) with established measures. The findings show that the Chinese, Malay and Tamil translations of the PMHI have high internal consistency and validity in this multi-ethnic population.

Gender difference in quality of life (QoL) among outpatients with schizophrenia in a tertiary care setting

BACKGROUND

Patients with mental illness report lower quality of life (QoL) compared to the general population. Prior research has found several differences in clinical features and experiences of male and female patients with schizophrenia. Given these differences, it is also important to explore if there are any gender differences in terms of their QoL. This study aimed to investigate differences in QoL between and within each gender among outpatients with schizophrenia in Singapore.

METHODS

A total of 140 outpatients were recruited through convenience sampling at the Institute of Mental Health, Singapore. QoL was measured using the brief version of World Health Organization Quality of Life (WHOQOL-BREF) which consists of four domains: physical health, psychological health, social relationships, and environment. QoL scores of males and females were compared using independent t-tests, and multiple linear regressions were used to examine sociodemographic correlates of QoL in the overall sample and within each gender.

RESULTS

There was no significant difference in QoL domain scores between genders. Among males, Indian ethnicity (versus Chinese ethnicity) was positively associated with physical health (β=3.03, p=0.018) while males having Technical Education/ Diploma/ A level education (versus Degree and above) were positively associated with social relationships domain (β=2.46, p=0.047). Among females, Malay ethnicity (versus Chinese ethnicity) was positively associated with physical health (β=1.95, p=0.026) psychological health (β=3.21, p=0.001) social relationships (β=2.17, p=0.048) and environment (β=2.69, p=0.006) domains, while females who were separated/divorced (versus single) were inversely associated with psychological health (β=- 2.80, p=0.044) and social relationships domains (β=- 4.33, p=0.011). Females who had Secondary and below education (versus Degree and above) were inversely associated with social relationships (β=- 2.29, p=0.028) and environment domains (β=- 1.79, p=0.048).

CONCLUSIONS

The findings show the importance of treatments targeting QoL to attend to both the clinical features of the illness as well patient's sociodemographic characteristics.

The association between caregiver burden, distress, psychiatric morbidity and healthcare utilization among persons with dementia in Singapore

BACKGROUND

Caregivers of persons with dementia (PWD) face high caregiving burden, distress related to responsive behaviours, and psychiatric morbidity. The present paper examines how these are associated with healthcare utilization of the PWD in Singapore.

METHODS

The data of 399 caregiver-PWD dyads were extracted from a national cross-sectional survey. PWD completed the Client Service Receipt Inventory, which provided information on their healthcare utilization (i.e. emergency service use, hospital admission, length of stay in hospital, and number of outpatient visits) within a frame of 3 months. The Zarit Burden Interview  (ZBI), Neuropsychiatric Inventory Questionnaire (NPI-Q), and Self Reporting Questionnaire (SRQ-20) were administered to caregivers. Information on severity of dementia, physical multimorbidity of the PWD, household composition, and caregivers' sociodemographic characteristics such as age, gender, and education were collected. Variables significantly associated with healthcare utilization in the univariate analyses were selected and included in the final regression models. Emergency service use and hospital admission were investigated using logistic regression analyses, whilst negative binomial models were utilized for length of stay in hospital and number of outpatient visits.

RESULTS

After adjusting for significant correlates such as dementia severity and multimorbidity, only caregiver distress from responsive behaviours was positively associated with emergency room utilization, while caregiver burden was positively associated with length of hospital stay in the final regression model. Psychiatric morbidity was associated with healthcare utilization outcomes at the univariate level but did not reach statistical significance in final models.

CONCLUSION

The study identifies caregiver variables associated with the healthcare utilization of PWD. Policy makers and healthcare professionals should provide interventions to ease burden and distress amongst caregivers of PWD.

Aggression Amongst Outpatients With Schizophrenia and Related Psychoses in a Tertiary Mental Health Institution

Aims: Aggression is defined as "any behavior intended to cause physical, emotional, or psychological harm to another." The aims of the current study were to (i) examine underlying factor structure of the Buss-Perry Aggression Questionnaire (BPAQ) and (ii) explore socio-demographic and clinical correlates (symptom severity, substance use and alcohol use) among patients with schizophrenia and related psychoses in a multi-ethnic Asian population. Methods: Data collected from 397 participants who were seeking outpatient treatment for schizophrenia and related psychoses at a tertiary psychiatric hospital were included in the analyses. BPAQ, a 29-item, four-factor instrument that measures physical aggression, verbal aggression, anger and hostility was used to assess aggression. Data on socio-demographic variables, age of onset of illness, drug use, alcohol use and symptom severity were also collected. Confirmatory factor analysis (CFA) was performed to establish the underlying factor structure of the BPAQ. Multiple regression analyses were utilized to examine socio-demographic and clinical correlates of the BPAQ factors. Results: The mean age of the participants was 36.2 years (SD = 10.9, range: 21-65). Factor structure obtained from the CFA indicated that a higher order four-factor solution had an acceptable fit to the observed data (WLSMV χ² = 1,025.35, df = 320, RMSEA = 0.07, CFI = 0.94, TLI = 0.93, SRMR = 0.05). Females had lower physical aggression and hostility scores as compared to males. Those with lower education had higher physical aggression scores as compared to those with higher education. Participants who received a diagnosis after the age of 30 years had higher physical aggression and anger scores as compared to those who received a diagnosis at or before 20 years of age. Symptom severity was positively associated with higher BPAQ scores. Conclusion: The study findings demonstrated high internal consistency and applicable measurement factor structure of BPAQ in this study sample, making it an appropriate questionnaire for assessing aggressive behavior in this population. We also identified socio-demographic and clinical factors that were associated with aggression in patients with schizophrenia and related psychoses.

Problematic Drug Use Among Outpatients With Schizophrenia and Related Psychoses

Background: Problematic drug use is common among psychiatric patients and is linked with poorer course and outcomes of illness. The aim of this study is to assess the prevalence of problematic drug use, and to explore its sociodemographic correlates and associations with health behaviors and outcomes among outpatients with schizophrenia and related psychoses in Singapore. Methods: Data from 397 individuals who were aged 21-65 years and were seeking treatment for schizophrenia and related psychoses in the outpatient clinics of a tertiary psychiatric hospital were analyzed. The Drug Abuse Screening Test (DAST-10) was used to assess problematic drug use. Information on sociodemographics, smoking status, alcohol use, symptoms severity and quality of life were collected. Multivariable logistic regressions were conducted to explore correlates and associations of problematic drug use. Results: The prevalence of problematic drug use was 5.8% (n = 23) in the sample, and 10.6% (n = 42) of the participants reported having problematic drug use and/or problematic alcohol use. More males than females reported having problematic drug use (p = 0.021), and also problematic drug and/or alcohol use (p = 0.004). Significant associations were observed between problematic drug use and smokers with nicotine dependence, and with physical health domain of quality of life. Individuals with greater symptom severity were approximately twice as likely to have problematic drug use and/or alcohol use. Conclusion: While the prevalence of problematic drug use in this sample population is relatively lower compared to other countries, there is a considerable number who might be at risk. Routine screening and close monitoring of drug use is recommended as part of psychiatric assessment, particularly among males and patients with nicotine dependence.

The association of mental disorders with perceived social support, and the role of marital status: results from a national cross-sectional survey

Background

This study investigated whether (i) mental disorders were associated with perceived social support and its subcomponents, (ii) current marital status was related to perceived social support, and (iii) ‘Married’ status influenced the relationship between mental state and perceived social support.

Methods

Data from a cross-sectional national survey comprising 6126 respondents were used. Lifetime diagnosis for five mental disorders was assessed with a structured questionnaire. Perceived social support was measured with the Multidimensional Scale of Perceived Social Support (MSPSS) that provides Global and subscale scores for Significant Other, Family and Friends. Multiple linear regression analyses were conducted to address the research questions with MSPSS score as the dependent variable. Structural equation modeling (SEM) was performed to test mediation by marital status.

Results

All mental disorders included in the study, except alcohol use disorder (AUD), were significantly and negatively associated with Global MSPSS scores. After controlling for sociodemographic factors and chronic physical illness, major depressive disorder (β = - 0.299, 95% CI: -0.484 – -0.113, p = 002) and having any of the five mental disorders (β = - 0.133, 95% CI: -0.254 – -0.012, p = 032) were negatively associated with support from Significant Other, while support from Family and Friends was lower among all disorders, except AUD. Being married was positively associated with perceived social support in people with and without mental disorders. Results of the SEM partially support mediation by mental state - perceived social support relationship by ‘Married’ status.

Conclusion

Having mental disorders was associated with lower perceived social support. Being married has potential to influence this relationship.

The Public Health Impact and Policy Implications of Online Support Group Use for Mental Health in Singapore: Cross-Sectional Survey

BACKGROUND

The wide mental health treatment gap continues to pose a global and local public health challenge. Online support groups are on the rise and could be used to complement formal treatment services for mental health.

OBJECTIVE

This study aimed to examine the prevalence of online support group use and explore factors associated with the use in the general population using data from a national cross-sectional mental health survey in Singapore.

METHODS

Singapore residents aged 18 years and above participated in a nationally representative household survey in which the World Health Organization Composite International Diagnostic Interview 3.0 was administered by trained interviewers to examine the use of online support groups for mental health. Multiple logistic regressions were used to analyze the association of online support group use with various sociodemographic and health factors.

RESULTS

A total of 6110 respondents with complete data were included in this study. Overall, 10 individuals per 1000 adults (1%) reported seeking help from online support groups for their mental health problems. Compared to younger adults (those aged 18 to 34 years) and those with university education, individuals aged 50 to 64 years (P<.001; OR 0.1, 95% CI 0.0-0.3) and those with preuniversity qualifications (P=.02; OR 0.1, 95% CI 0.0-0.8) were less likely to use online support groups for mental health, respectively. Participants with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) mental disorder were 6.8 times more likely (P<.001; 95% CI 3.0-15.4) to use an online support group; in particular, individuals with major depressive disorder (P<.001; OR 5.4, 95% CI 2.1-13.8) and obsessive compulsive disorder (P=.01; OR 3.5, 95% CI 1.3-9.7) were more likely to use an online support group for their mental health.

CONCLUSIONS

Online support groups could be used to complement formal treatment services, especially for mood and anxiety-related disorders. As online support group use for mental health issues may be more prevalent among younger people, early detection and accurate information in online support groups may guide individuals toward seeking professional help for their mental health problems.

Study protocol for a nationwide Knowledge, Attitudes and Practices (KAP) survey on diabetes in Singapore's general population

INTRODUCTION

This study aims to establish the Knowledge, Attitudes and Practices (KAP) of the general population (people with and without diabetes) towards diabetes. The study will examine (a) recognition and understanding of causes, prevention and treatment strategies of diabetes; (b) identify the knowledge gaps and behavioural patterns that may hamper diabetes prevention and control; (c) stigma towards and stigma perceived by people with diabetes and (d) awareness of anti-diabetes campaigns.

METHODS AND ANALYSIS

The study is a nationwide, cross-sectional study of Singapore's general population aged 18 years and above (n=3000), comprising Chinese, Malay, Indian and other ethnic groups, who can understand English, Chinese, Malay or Tamil language. The sample was derived using a disproportionate stratified sampling using age and ethnicity. The proportion of respondents in each ethnic group (Chinese, Malay and Indian) was set to approximately 30%, while the proportion of respondents in each age group was set around 20% in order to ensure a sufficient sample size. The respondents will be administered questionnaires on diabetes KAP, stigma towards diabetes, lifestyle, diet and awareness of local anti-diabetes campaigns. The analysis will include descriptive statistics and multiple logistic and linear regression analyses to determine the socio-demographic correlates of correct recognition of diabetes, help-seeking preferences, as well as overall knowledge and attitudes among those with and without diabetes. We will consider a p value ≤0.05 as significant.

ETHICS AND DISSEMINATION

This study protocol has been reviewed by the Institutional Research Review Committee and the National Healthcare Group Domain Specific Review Board (NHG DSRB Ref 2018/00430). The results of the study will be shared with policymakers and other stakeholders. There will be a local mass media briefing to disseminate the findings online, in print and on television and radio. The results will be published in peer-reviewed journals and presented in scientific meetings.

Caregivers' causal attributions of their relatives' mental illness and the association with stigma

Causal attributions of mental illness have received substantial attention given their influence on help-seeking patterns of individuals and the level of engagement with health services. Few studies, however, have examined caregivers' perspectives of their relatives' illness. The current study aimed to examine caregivers' causal attributions of their relatives' mental illness and its association with perceived stigma in a multi-ethnic Asian sample. Primary caregivers (N = 350) of psychiatric outpatients were recruited from a psychiatric hospital. The attribution and stigma sections of the Family Interview Schedule (FIS) were utilized to obtain caregivers' causal report of their relatives' illness and stigma perception. Logistic regressions were performed to examine the socio-demographic and diagnostic correlates of the four categories of causal attributions (psychosocial, biological, drug-/substance use-related, supernatural). The majority of caregivers identified psychosocial causes, followed by biological, supernatural, and lastly drug-/substance use-related causes for their relatives' illness. Marital status, religion, employment status and the diagnosis of depressive disorders were significant correlates of biological attributions. Ethnicity and not knowing their relatives' diagnosis were significantly associated with psychosocial attributions. For drug-/substance use-related attributions, ethnicity was the only significant correlate. Supernatural attributions did not yield any significant associations. Caregivers who endorsed drug-/substance use-related reasons also reported significantly higher stigma than caregivers who did not endorse these attributions. A tendency to endorse biological and psychosocial causes for their relative's illness was noted among caregivers. Further research on caregivers' causal attributions is warranted to account for and replicate current study findings.

Understanding the relationships between mental disorders, self-reported health outcomes and positive mental health: findings from a national survey

BACKGROUND

The link between mental illness and mental health is gaining focus in research and practice. This study aimed to investigate the association of mental disorders with positive mental health (PMH), overall health and quality of life. In addition, the role of PMH in mediating the relationships between mental disorders and health outcomes was assessed.

METHODS

The study sample comprised 2270 residents aged 18 years and above who participated in a nationally representative, cross-sectional survey estimating the lifetime prevalence of mood, anxiety and alcohol use disorders, and health outcomes (self-reported overall health, quality of life and PMH) in Singapore. The Positive Mental Health Instrument was used to estimate the level of Total PMH among the respondents with and without mental disorders. Associations between mental disorders and health outcomes were assessed through regression models. Path analyses were conducted to investigate mediating role of PMH.

RESULTS

Total PMH (Mean ± SD) was significantly lower among individuals having any of the studied lifetime mental disorders (4.23 ± 0.64 versus 4.50 ± 0.67 among those without these disorders). Although having a mood or anxiety disorder was associated with significantly lower Total PMH even after controlling for socio-demographic characteristics, similar relationship was not observed for alcohol use disorders. History of any mental disorders was also associated with lower overall health and quality of life. Total PMH mediated the relationships between mental disorders and overall health and quality of life by reducing the effect sizes for the associations between mental disorders and these health outcomes.

CONCLUSIONS

Mental disorders were associated with poor health outcomes in affected individuals. This study showed that PMH can mediate the relationships between mental disorders and health outcomes, and act as an underlying mechanism to improve overall health and quality of life in individuals with mental disorders. Findings thus highlight the significance of incorporating mental health promotion and interventions in clinical populations.

An exploratory study on the lived experiences of hoarding in Singapore

Research studies have revealed that people with hoarding typically collect and keep items due to their aesthetic appeal, utility and strong emotional attachment to the items resulting in clutter and limiting living spaces. This study aims to explore the experiences of individuals with hoarding disorder to understand and describe-the patterns and reasons for hoarding, experiences with decluttering and the impact of hoarding disorder on significant others and society in the context of a multi-ethnic urban Asian country. A total of 12 participants with hoarding disorder were recruited and interviewed using a simple semi-structured interview guide designed for the study. The resulting transcribed interviews were analysed using thematic analysis. The mean age of the participants was 56.7 years (SD = 14.5). Nine super-ordinate and discrete but interconnecting themes emerged from the qualitative interviews: types of hoarded items, sources of hoarded items, ways of storing/arranging hoarded items, help-seeking/treatment contact, reasons for hoarding, experiences with decluttering, impact upon family, community and self, restricting hoarding behaviours and insight. Key themes identified in the study are consistent with the literature on studies on hoarding which have been done in other populations. Hoarding in the community has serious consequences for individuals with hoarding disorder and others living in the community, which is compounded by the lack of insight among these individuals. There is a pressing need to increase public awareness and recognition of hoarding behaviours to aid efforts in bringing timely and appropriate services to the affected individuals.

Obsessive-Compulsive Disorder in Singapore: Prevalence, Comorbidity, Quality of Life and Social Support

Introduction: Using data from Singapore Mental Health Study 2016 (SMHS 2016), we examined the prevalence of lifetime and 12-month obsessive-compulsive disorder (OCD),its sociodemographics correlates and association with comorbid psychiatric disorders and physical conditions, perceived social support and quality of life. Materials and Methods: The World Mental Health Composite International Diagnostic Interview (version 3.0) was administered by trained interviewers to 6126 residents aged ≥18 years old to assess OCD prevalence and that of other select psychiatric disorders. Details on sociodemographics, perceived social support and health-related quality of life were obtained. Results: Lifetimeand 12-month prevalence of OCD was 3.6% and 2.9%, respectively. Adjusted regression analysis showed that those with OCD had significantly higher odds of major depressive disorder (odds ratio [OR], 5.4), bipolar disorder (OR, 8.9), generalised anxiety disorder (OR, 7.3) and alcohol abuse (OR, 2.7). OCD was significantly associated with suicidal ideation and suicidality (OR, 5.1). OCD subjects also had higher odds of chronic pain (OR, 2.4) and diabetes (OR, 3.1). Finally, OCD subjects had lower mean mental composite summary scores than controls (respondents without any of the psychiatric disorders and physical conditions included in SMHS 2016) and those with other lifetime psychiatric disorders and physical conditions. Conclusion: OCD prevalence in Singapore is high. Most people with OCD do not seek treatment despite experiencing significant comorbidity and loss of quality of life. Key words: Composite International Diagnostic Interview, Epidemiology, Multi-ethnic, Psychiatric disorder, Survey

Obsessive-Compulsive Disorder in Singapore: Prevalence, Comorbidity, Quality of Life and Social Support

INTRODUCTION

Using data from Singapore Mental Health Study 2016 (SMHS 2016), we examined the prevalence of lifetime and 12-month obsessive-compulsive disorder (OCD), its sociodemographic correlates and association with comorbid psychiatric disorders and physical conditions, perceived social support and quality of life.

MATERIALS AND METHODS

The World Mental Health Composite International Diagnostic Interview (version 3.0) was administered by trained interviewers to 6126 residents aged ≥18 years old to assess OCD prevalence and that of other select psychiatric disorders. Details on sociodemographics, perceived social support and health-related quality of life were obtained.

RESULTS

Lifetime and 12-month prevalence of OCD was 3.6% and 2.9%, respectively. Adjusted regression analysis showed that those with OCD had significantly higher odds of major depressive disorder (odds ratio [OR], 5.4), bipolar disorder (OR, 8.9), generalised anxiety disorder (OR, 7.3) and alcohol abuse (OR, 2.7). OCD was significantly associated with suicidal ideation and suicidality (OR, 5.1). OCD subjects also had higher odds of chronic pain (OR, 2.4) and diabetes (OR, 3.1). Finally, OCD subjects had lower mean mental composite summary scores than controls (respondents without any of the psychiatric disorders and physical conditions included in SMHS 2016) and those with other lifetime psychiatric disorders and physical conditions.

CONCLUSION

OCD prevalence in Singapore is high. Most people with OCD do not seek treatment despite experiencing significant comorbidity and loss of quality of life.

Prevalence and comorbidity of migraine headache: results from the Singapore Mental Health Study 2016

BACKGROUND AND AIM

Migraine is a highly prevalent and disabling neurological disorder associated with a wide range of psychiatric comorbidities. Studies have revealed that those with migraine headache and coexisting psychiatric disorders have poorer treatment outcomes and increased disability. The study aims to establish the prevalence, correlates, and comorbidities of migraine headache among the multi-ethnic Asian population in Singapore.

METHOD

Data were extracted from the Singapore Mental Health Study 2016 (SMHS 2016), a cross-sectional epidemiological survey of a nationally representative sample. Face-to-face interviews were completed with 6126 participants between 2016 and 2017. The data relating to chronic medical conditions, psychiatric conditions, and 30-day functioning and disability were captured using the World Mental Health Composite International Diagnostic Interview (CIDI) version 3.0.

RESULTS

The lifetime prevalence for migraine headache in the Singapore general population was 8.2%. Malay ethnicity (versus Chinese), female gender (versus male), and diploma holders (versus university) were significantly more likely to experience migraine headache. Participants belonging to the older age group (65 years and above versus 18-34 years of age), and those who were economically inactive (versus employed) were less likely to experience migraine headache. The mean age of onset for migraine was 26.4 years (SD = 11.1). Poisson regression analyses showed that migraine headache was also significantly associated with psychiatric conditions such as major depressive disorder (MDD) (prevalence ratio (PR), 1.80; 95% CI, 1.25-2.58), bipolar disorder (BD) (PR, 3.55; 95% CI, 2.29-5.51), generalized anxiety disorder (GAD) (PR, 2.04; 95% CI, 1.12-3.69), obsessive compulsive disorder (OCD) (PR, 2.20; 95% CI, 1.49-3.26), and alcohol use disorder (AUD) (PR, 1.93; 95% CI, 1.20-3.08). Those with migraine headache were significantly associated with poor functioning and disability compared to those without migraine headache.

CONCLUSIONS AND DISCUSSION

Our study showed significant associations between migraine headache and psychiatric disorders, as well as with role functioning and disability. The findings of our study emphasise the need for screening for psychiatric comorbidity among those with migraine and the development of appropriate interventions for this group.

Cognitive insight and quality of life among psychiatric outpatients

BACKGROUND

Past studies have focused primarily on clinical insight and less on cognitive insight among individuals with mental illness.

METHODS

This study examined the level of cognitive insight (CI) and its association with quality of life (QoL) among psychiatric outpatients (N = 400) in Singapore. The Beck Cognitive Insight Scale (BCIS) consisting of two subscales (self-reflectiveness (SR) and self-certainty (SC)) was used to measure CI while the brief version of the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire was used to assess the subjective well-being of the individual.

RESULTS

Socio-demographic correlates of CI, differences in SR, SC, and CI scores across diagnostic groups, and the association between insight and QoL were examined. Significant differences across diagnostic groups were found only for SR scores. Higher SR and overall CI scores were significantly associated with higher QoL in the environmental domain whereas higher SC scores were associated with lower QoL in the social relationships domain.

CONCLUSIONS

An understanding of cognitive insight is necessary to produce a significant change in the underlying belief system of an individual. Together with clinical insight, these two forms of insight can be used to inform therapeutic approaches to increase awareness and improve the QoL of those with mental illnesses.

Exploring Singapore's consumption of local fish, vegetables and fruits, meat and problematic alcohol use as risk factors of depression and subsyndromal depression in older adults

Background

Depression is a chronic mental disorder that severely impacts the older adult population globally. Nutritional psychiatry is an approach that has gained traction over the years. Exploring locally relevant consumption of common types of fish, vegetables and fruits (V&F), meat and problematic alcohol use (PAU) as risk factors associated with depression and subsyndromal depression (SSD) could reveal modifiable factors that could be targeted in the local older adult population in Singapore.

Methods

Data collected from the Well-being of the Singapore Elderly (WiSE) study, a cross-sectional population-based epidemiological study of Singapore’s older adult population was analysed for the purposes of this study. Two thousand five hundred sixty-five participants were recruited and comprised of Singapore citizens and permanent residents aged ≥60 years. Data on fish, meat, and V&F consumption were collected using the sociodemographic and risk factor questionnaire. The CAGE (Cut, Annoyed, Guilt, and Eye-opener) questionnaire was used to determine PAU. The Geriatric Mental State-Automated Geriatric Examination for Computer Assisted Taxonomy (GMS-AGECAT) was used to obtain participants’ diagnosis of depression or SSD. A multinomial logistic regression was used to explore the relationship between depression and dietary factors.

Results

Consumption of V&F in the last 3 days was less likely to be associated with depression and SSD. Frequent consumption of specific species of fish was associated with depression and SSD. PAU and the frequent consumption of Himantura gerrardi (stingray) were more likely to be associated with SSD. Finally, meat consumption was more likely to be associated with depression and SSD.

Conclusions

The preliminary findings of the study support a need for healthy eating for the older adult population in Singapore. Further directions include a more thorough health and nutrition survey to capture accurate diets among the older adults in Singapore.

Social support network typologies and their association with dementia and depression among older adults in Singapore: a cross-sectional analysis

OBJECTIVES

To examine the social support network type and its associations with depression and dementia among older adults in Singapore.

DESIGN

This study is a cross-sectional analysis of data from the Well-being of the Singapore Elderly study. The Practitioner Assessment of Network Type was used to identify five social support network types. Odds Ratios (OR) of dementia and depression were estimated with logistic regression and multinomial logistic regression, respectively, adjusted for sociodemographic variables.

SETTING

Singapore.

OUTCOME MEASURES

10/66 criteria and Automated Geriatric Examination for Computer Assisted Taxonomy computer algorithm.

PARTICIPANTS

2421 older adults aged 60 years and above, and their informants.

RESULTS

Logistic regression revealed that as compared with participants in the family dependent social support network type, those in the locally integrated social support network type were negatively associated with dementia. It was observed that it is the older adults' perception of the quality of social interaction that influences the likelihood of depression.

CONCLUSION

The social support network typology presents knowledge about the older adults' social network profile and their cognitive functioning-ability which would help stakeholders better identify older adults who might be at risk of cognitive decline or experiencing delay in diagnosis of dementia.

Exploration of illness perception among patients with mental illness in a multi-ethnic Asian sample

Illness perceptions are beliefs that patients have about their illness. These beliefs play an important role in influencing their behaviour and outcomes. This study examined the factor structure and correlates of the Illness Perception Questionnaire Mental Health (IPQ-MH) among patients with mental illness in a multi-ethnic Asian sample. 400 participants with schizophrenia and other psychotic disorders, mood or anxiety disorder were recruited from a tertiary psychiatric institution and administered the IPQ-MH. Data on sociodemographic variables were also collected. A multi-factor structure was identified for the Identity, Structure and Cause subscale of the IPQ-MH. Age was consistently associated with a positive perception of illness across all three disorders; women had a more positive perception of schizophrenia and other psychotic disorders as compared to men while those of Indian ethnicity had a more negative perception of their mood disorder as compared to those of Chinese ethnicity. Those with lower education had a poorer understanding of their illness among those with mood disorder, and a poorer understanding of their illness and the effectiveness of treatment among those with anxiety disorder. The study identified specific groups which can be targeted through tailored and culturally relevant psychoeducational interventions to enhance their understanding and perception of mental illness.

Pathways to care among psychiatric outpatients in a tertiary mental health institution in Singapore

BACKGROUND

Pathways to care studies in Singapore are of high interest given the cultural diversity and various sources of help available for those with mental illnesses, ranging from the more traditional to tertiary-level mental health care services.

AIM

The current study aimed to explore the associations of patients' socio-demographic characteristics with pathways to first contact and duration of untreated mental illness.

METHOD

A total of 402 participants were recruited through convenience sampling. A pathway to care form was used to gather systematic information about the sources of care utilized by participants before approaching a mental health professional. Data were analysed using multinomial logistic regression and multiple linear regression models to assess the associations.

RESULTS

Majority of participants reported primary care (36.0%) as their first point of contact, followed by non-formal sources of help (33.8%), specialist care (21.8%), police/court (4.0%), websites/media (3.3%) and religious/traditional treatment (1.3%). Those belonging to Malay and Indian ethnicity (vs Chinese) were more likely to make first contact with non-formal sources of help than primary care. Those who received a diagnosis of any mood or anxiety disorder (vs schizophrenia and related psychoses) were less likely to make first contact with specialist care or non-formal sources of help than primary care. Those who were separated/divorced/widowed were significantly associated with higher duration of untreated illness compared to those who were single. Participants whose family/relative initiated the first contact were significantly associated with a shorter duration of untreated illness compared to those who initiated first contact on their own.

CONCLUSION

Findings suggest the determinants of the pathways to first contact and duration of untreated illness included diagnosis, ethnicity, marital status and family initiating the first contact. The pathways adopted by these participants need to be kept in mind for planning mental health programmes.

Affiliate stigma and its association with quality of life among caregivers of relatives with mental illness in Singapore

Affiliated stigma often refers to internalized stigma among family members of stigmatized individuals. This study aimed to investigate the relationship between affiliate stigma and quality of life (QOL) among primary caregivers of individuals with mental illness undergoing treatment at the Institute of Mental Health, Singapore. Three hundred and fifty caregivers were recruited for the study. The World Health Organization Quality of Life questionnaire (WHOQOL-BREF) and Family Stigma Scale (FSS) were administered to the primary caregivers of patients with mental illness. Multiple linear regression analyses were conducted to investigate the association of affiliate stigma with QOL. A high proportion of caregivers of individuals with mental illness experience affiliate stigma in Singapore. All four QOL domains were significantly associated with affiliate stigma. These findings entail that it is imperative to improve public's perception of those with mental illness to reduce stigmatization and thus improve caregiver's QOL.

Predictors of General Functioning and Correlates of Quality of Life: A Cross-Sectional Study among Psychiatric Outpatients

INTRODUCTION

Functioning and quality of life (QOL) are negatively impacted as a result of mental illness. This study aimed to determine the: i) socio-demographic and clinical correlates of functioning and; ii) associations between functioning and QOL in a multiethnic sample of psychiatric outpatients.

MATERIALS AND METHODS

This was a cross-sectional study of outpatients receiving treatment from a tertiary psychiatric hospital. Functioning was assessed using the Global Assessment of Functioning (GAF) scale, while QOL was measured using the World Health Organization Quality of Life-BREF (WHOQOL-BREF) which comprises 4 domains: physical health, psychological health, social relationships and environment.

RESULTS

Various socio-demographic and clinical correlates were associated with functioning including employment and marital status, education and diagnosis. Depression was the only clinical characteristic which negatively correlated with functioning (P = 0.035). Amongst the whole sample, multiple linear regressions revealed that functioning was positively associated with all 4 QOL domains (physical health [P <0.001], psychological health [P <0.001], social relationships [P <0.001] and environment [P <0.001]). Further analysis of each diagnostic group revealed that functioning was positively associated with all 4 QOL domains in the anxiety, depression and obsessive compulsive disorder subsamples, while in the schizophrenia subsample, functioning was only significantly associated with all environment domain.

CONCLUSION

Functional impairments were associated with different socio-demographic and clinical characteristics, which should be addressed when planning tailored treatment and interventions. Given that functioning is significantly associated with QOL, it is crucial to regularly assess and monitor them (in addition to symptomatic outcomes and adopting a more holistic and biopsychosocial approach).

Head circumference, leg length and its association with dementia among older adult population in Singapore

BACKGROUND

Head circumference and leg length serve as reliable proxy indicators of early-life environment. Research studies have shown that these anthropometric measurements are associated with cognitive impairment and dementia among older adults. The aim of the present study was to assess the associations between dementia with head circumference and leg length among the older adult population in Singapore. This study also aimed to examine the sociodemographic correlates of these anthropometric measurements.

METHODS

Data were collected from 2565 older adults aged 60 years and above, in a population study on the Well-being of the Singapore Elderly. Head circumference and leg length measurements were obtained, and sociodemographic information was recorded. Dementia diagnosis was made using the 10/66 dementia algorithm. Anthropometric measurements were first stratified into quarters, and then logistic regression analysis was used to examine factors associated with head circumference and leg length, as well as to examine the association between dementia with these measurements.

RESULTS

Sociodemographic correlates of head circumference and leg length include age, gender, ethnicity and education level. Smaller head circumference was independently associated with higher odds of 10/66 dementia (OR = 2.173-2.709). When the regression analysis was stratified by gender, the association was found only in the male sample. Leg length was not significantly associated with dementia after controlling for sociodemographic variables.

CONCLUSION

Smaller head circumference is independently associated with dementia among older adults in Singapore. Findings from this study suggest that risk factors for dementia begin their influence in early life. Copyright © 2017 John Wiley & Sons, Ltd.
