Cognitive distortions among older adult gamblers in an Asian context

Aims

The study aims to describe the construct of cognitive distortions based on the narratives of older adult gamblers (aged 60 years and above) in Singapore.

Methods

Singapore residents (citizens or permanent residents) aged 60 years and above, who were current or past regular gamblers were included in the study. Participants were recruited using a combination of venue based approach, referrals from service providers as well as by snowball sampling. In all, 25 in-depth interviews were conducted with older adult gamblers. The six-step thematic network analysis methodology was adopted for data analysis.

Results

The mean age of the participants was 66.2 years. The majority were male (n = 18), of Chinese ethnicity (n = 16), with a mean age of gambling initiation at 24.5 years. Among older adult gamblers, cognitive distortions emerged as a significant global theme comprising three organizing themes–illusion of control, probability control and interpretive control. The organizing themes comprised nine basic themes: perception of gambling as a skill, near miss, concept of luck, superstitious beliefs, entrapment, gambler’s fallacy, chasing wins, chasing losses, and beliefs that wins are more than losses.

Conclusions

Cognitive distortions were endorsed by all gamblers in the current study and were shown to play a role in both maintaining and escalating the gambling behaviour. While the surface characteristics of the distortions had a culture-specific appearance, the deeper characteristics of the distortions may in fact be more universal than previously thought. Future research must include longitudinal studies to understand causal relationships between cognitive distortions and gambling as well as the role of culture-specific distortions both in the maintenance and treatment of the disorder.

Why is psychiatric nursing not the preferred option for nursing students: A cross-sectional study examining pre-nursing and nursing school factors

BACKGROUND

There is a shortage of nurses working in the mental health field globally. The aim of the present study was to examine Singapore nursing students' attitudes towards specializing in psychiatric nursing by examining the pre-nursing and nursing school factors as well as attitudes towards psychiatry and personality traits.

METHODS

A cross-sectional online survey was conducted with 500 nursing students from four nursing institutions in Singapore. Students' attitudes towards psychiatry (ATP-18), perception of psychiatric nursing career aspects relative to other fields, and personality traits (mini-IPIP) were assessed. The main outcome measure was likelihood of specializing in psychiatric nursing. Logistic regression was used to examine the combined effect of factors upon the outcome.

RESULTS

Twenty-six students (5.2%) rated "definitely decided to do" psychiatric nursing. Pre-nursing school factors associated with choosing psychiatry included ethnicity, current education, parents' wishes, having personal/family experience of mental illness, prior work experience, interest in psychiatric nursing and psychology module taken prior to current school admission. Nursing school factors such as teaching methods and clinical exposure were not associated with choosing psychiatric nursing. Positive attitudes towards psychiatry, perception of better career aspects in psychiatric nursing relative to other fields, and the personality traits of extraversion and intellect/imagination were associated with likelihood of choosing psychiatric nursing. Logistic regression revealed Malay (OR: 1.90, 1.14-3.16, p=0.013) and Indian ethnicity (OR: 2.56, 1.32-4.96, p=0.005), interest in psychiatry (OR: 22.56, 8.22-61.92, p<0.001), psychology module prior to current school admission (OR: 2.31, 1.28-4.17, p=0.005), better perceived job prospects in psychiatric nursing than other fields (OR: 1.91, 1.21-3.04, p=0.006), extraversion (OR: 1.09, 1.02-1.17, p=0.012) and positive attitude towards psychiatry (OR: 2.72, 1.75-4.23, p<0.001) as factors associated with students choosing psychiatric nursing.

CONCLUSIONS

The selection of psychiatry as a specialty by nursing students was affected by pre-nursing school factors. Taking these factors into consideration may improve recruitment and alleviate the shortages in the psychiatric nursing field.

Emotion dysregulation as a mechanism linking child maltreatment exposure and self-harm behaviors in adolescents

Although child maltreatment exposure is a recognized risk factor for self-harm, mechanisms underlying this relationship remain unclear. Self-harm may function as a compensatory strategy to regulate distressing emotions. This cross-sectional study examines if emotion dysregulation mediates between the severity of maltreatment exposure and self-harm, adjusting for demographic variables and depressive symptoms. Participants were 108 adolescent patients recruited from a psychiatric hospital in Singapore (mean age 17.0 years, SD=1.65; 59.3% female). Study measures included the Childhood Trauma Questionnaire (CTQ-SF), Functional Assessment of Self-Mutilation (FASM), Difficulties in Emotion Regulation Scale (DERS), and the Patient Health Questionnaire (PHQ-8). Path analysis was conducted to examine the direct and indirect effects of maltreatment exposure on self-harm via emotion dysregulation, controlling for demographic variables and depressive symptoms. Indirect effects were tested using bootstrapped confidence intervals (CI). Results showed that self-harm was highly prevalent in our sample (75.9%). Emotion dysregulation and depressive symptoms were found to be associated with higher self-harm frequency. In addition, results from path analysis showed that the association between the severity of maltreatment exposure and self-harm frequency was significantly mediated by emotion dysregulation B=0.07, p<0.05, 95% CI [0.02, 0.16]. Thus, emotion dysregulation may be a proximal mechanism linking maltreatment exposure and adolescent self-harm. Notably, self-harm may represent maladaptive attempts to manage emotion dysregulation that may have resulted from maltreatment. Findings from the study have implications for the prevention and treatment of self-harm in maltreated youth.

Employment status among the Singapore elderly and its correlates

AIM

It has been hypothesized that working beyond retirement age may have a protective effect on various aspects of well-being in the elderly. This paper aims to examine the relationship between employment status of elderly Singaporeans and indicators of well-being.

METHODS

As part of the Well-being of the Singapore Elderly study, data relating to sociodemographics, social networks, medical history, physical activity, cognitive function, and disability were collected from 2534 participants aged 60 years and older. Participants included full-time workers (n = 483), part-time workers (n = 205), the unemployed (n = 32), homemakers (n = 808), and retirees (n = 1006). The data were analyzed by multiple logistic regression.

RESULTS

Likelihood of being employed decreased with age, and employment was higher among men. Paid workers had significantly higher levels of physical activity, more extensive social networks, better cognitive function, less disability, and lower risk of dementia than retirees and homemakers. Paid workers had significantly lower chronic disease burden than retirees and rated their health to be better than retirees and the unemployed.

CONCLUSIONS

These findings show that meaningful employment is associated with better psychological and physiological well-being among the elderly, highlighting the importance of studying likely protective effects of employment and creating employment opportunities for elderly Singaporeans.

Validation of the short version of the 10/66 dementia diagnosis in multiethnic Asian older adults in Singapore

Background

To validate the short version of the 10/66 dementia diagnosis against the standard version of the 10/66 dementia diagnosis and clinical diagnosis and examine concurrent validity with the World Health Organisation Disability Assessment schedule and care needs in a multiethnic Asian older adult population in Singapore.

Methods

Data from the Well-being of the Singapore Elderly study, a nationally representative survey of the older Singapore Resident population aged 60 years and above was used. The validity of the short version of the 10/66 dementia diagnostic criteria derived from the Community Screening Instrument for Dementia, the modified Consortium to Establish a Registry of Alzheimer’s Disease 10-word list delayed recall and the EURO-D depression screen were examined against the standard version of the 10/66 dementia diagnosis and clinician diagnosis as a gold standard. Concurrent validity was tested by examining the relationships between the short version 10/66 dementia diagnosis, disability and care needs.

Results

A total of 2373 respondents who had completed data on the short version diagnosis were included in this study. The majority (82.63%) of respondents were of Chinese descent, 9.86% were Malays, 6.12% were of Indian descent and 1.39% belonged to other ethnic group. We found the short version 10/66 dementia diagnosis showed almost perfect agreement with the standard version 10/66 dementia diagnosis (kappa = 0.90, AUC = 0.96) and substantial agreement with clinical diagnosis (kappa = 0.70, AUC = 0.87). The weighted prevalence of dementia in the population was slightly higher based on the short version diagnosis than the standard version diagnosis (10.74% vs. 10.04%). We also found that those with the short version 10/66 dementia were significantly associated with higher disability (β = 28.90, 95% CI = 23.62, 9.62) and needed care occasionally (OR =35.21, 95% CI = 18.08, 68.59) or much of the time (OR = 9.02, 95% CI = 5.21, 15.61).

Conclusions

The study found that the short version 10/66 dementia diagnosis has excellent validity to diagnose dementia in a multiethnic Asian population in Singapore. Further research is required to determine the usefulness of this diagnosis in clinical practice or institutional settings to aid early detection and intervention for dementia.

Continuum beliefs and stigmatising beliefs about mental illness: results from an Asian community survey

OBJECTIVES

To establish the prevalence and correlates of continuum beliefs for five mental illnesses in a multiethnic population and to explore its association with stigma.

DESIGN

A community-based, cross-sectional study.

SETTING

A national study in a multiethnic Asian country.

PARTICIPANTS

A comprehensive study of 3006 Singapore residents (Singapore citizens and permanent residents) aged 18-65 years who were living in Singapore at the time of the survey.

OUTCOME MEASURES

Parameters assessed included belief in a continuum of symptom experience, stigma dimensions and causal beliefs in mental illness. Statistical analyses included descriptive statistics and multiple linear regression (MLR).

RESULTS

About half of the population indicated agreement with a continuum of symptoms for depression (57.9%) and dementia (46.8%), whereas only about one in three respondents agreed with it for alcohol abuse (35.6%), schizophrenia (32.7%) and obsessive-compulsive disorder (OCD) (36.8%). MLR analyses revealed that students (β=0.28; 95% CI 0.05 to 0.50; p=0.018) and those who were unemployed (β=0.60; 95% CI 0.26 to 0.95; p=0.001) (vs employed) as well as those who had previous contact with people with mental illness (β = 0.31; 95% CI 0.18 to 0.45; p<0.001) and believed stress, family arguments, difficulties at work or financial difficulties to be a cause for mental illness (β=0.43; 95% CI 0.13 to 0.73; p=0.005) were associated with a higher belief in a continuum of symptom experience. Continuum beliefs were related to lower desire for social distance in alcohol abuse, OCD and schizophrenia; however, they were associated with higher scores on 'weak-not-sick' stigma dimension in dementia and schizophrenia.

CONCLUSIONS

Perceiving that a person with a mental illness is similar to themselves may reduce social distancing by the public. Thus, the approach may lend itself well to public education aimed at reducing stigma.

Responsible gambling among older adults: a qualitative exploration

BACKGROUND

Responsible gambling (RG) is defined as gambling for pleasure and entertainment but with an awareness of the likelihood of losing, an understanding of the associated risks and the ability to exercise control over one's gambling activity. The current study describes a qualitative approach to explore RG among older adults (aged 60 years and above) in Singapore and reports on the cognitive and behavioural strategies employed by them to regulate their gambling.

METHODS

Inclusion criteria included Singapore residents aged 60 years and above, who could speak in English, Chinese, Malay or Tamil and were current or past regular gamblers. Participants were recruited using a combination of network and purposive sampling. Socio-demographic information on age, age of onset of gambling, gender, ethnicity, marital status, education and employment was collected. The South Oaks Gambling Screen (SOGS) was used to collect information on gambling activities and problems associated with gambling behaviour. Qualitative interviews were conducted with 25 older adults (60 years and above) who currently gambled. The data was analyzed using thematic network analysis.

RESULTS

This global theme of RG comprised two organising themes: self -developed strategies to limit gambling related harm and family interventions to reduce gambling harm. The basic themes included delayed gratification, perception of futility of gambling, setting limits, maintaining balance, help-seeking and awareness of disordered gambling in self or in others. Family interventions included pleading and threatening, compelling help-seeking as well as family exclusion order.

CONCLUSIONS

The study highlights the significant role that families play in Asian societies in imposing RG. Education of family members both in terms of the importance of RG, and communication of the ways in which older adults can incorporate RG behaviours including the use of exclusion in specific scenarios is important.

Gender differences in positive mental health among individuals with schizophrenia

OBJECTIVE

This article aims to investigate the gender differences in positive mental health among outpatients with schizophrenia.

METHODS

142 outpatients (aged 21-65 years) with schizophrenia spectrum disorders were recruited from a tertiary psychiatric hospital. They were administered the following instruments: The Positive Mental Health (PMH) instrument, Patient Health Questionnaire (PHQ)-8 and Generalized Anxiety Disorder (GAD)-7, and the Global Assessment of Functioning (GAF) scale. Socio-demographic and clinical characteristics were gathered from interviews with the participants as well as from their medical records. Independent t-tests and chi-square tests were performed to investigate the gender differences in PMH total and domain-specific scores. Association of socio-demographic and clinical characteristics with PMH was furthered explored in men and women independently using multiple linear regression analyses using backward stepwise method.

RESULTS

PMH total score and Emotional Support (ES) and Global Affect (GA) sub-scale scores were significantly higher among women vs men (PMH = 4.41 vs 4.07, p value = 0.01 and domains ES = 4.56 vs 3.84, p value < 0.01 and GA = 4.44 vs 4.02, p value = 0.01), given that the men and women samples did not differ significantly in their socio-demographic and clinical profiles. After adjusting for all covariates, men with no formal/ primary education were significantly associated with lower PMH total score than those with higher (secondary, A level, pre-university) education. Men belonging to Malay ethnic group had significant higher PMH total score compared to men of Chinese ethnicity. Among the women samples, those with depression as measured by PHQ-8 had significantly lower scores in the PMH total score and higher GAF score was associated with significantly higher scores in PMH total score.

CONCLUSIONS

This study identified gender differences in PMH of patients with schizophrenia spectrum disorders whereby women had higher PMH total score and domain scores than men. The study also identified factors associated with PMH which can aid in designing gender appropriate mental health interventions.

The mediational role of physical activity, social contact and stroke on the association between age, education, employment and dementia in an Asian older adult population

BACKGROUND

Our study aimed to investigate the pathways by which socio-demographic factors, modifiable health and lifestyle risk factors influence each other, and subsequently, lead to dementia.

METHODS

We used data from the Well-being of the Singapore Elderly study, a nationally representative survey of the older adult population aged 60 years and above in Singapore. Dementia diagnosis was established using 10/66 dementia criteria. Structural equation modelling (SEM) without latent variable was applied to confirm the hypothesized model.

RESULTS

The results of SEM supported the hypothesized model (χ ² = 14.999, df = 10, p = 0.132). The final model showed that those aged 75-84 years and 85 years and over (vs. 60-74 years), having no formal education, who had completed primary or secondary education (vs. completed tertiary), who were homemakers and retired (vs. paid work), and with a history of stroke were directly associated with higher odds of having dementia, while those who had more frequent contact with friends and neighbors as well as being physically active were directly associated with lower odds of having dementia diagnosis. The study also found that physical activity, more frequent contact with friends and stroke played a significant role as mediators in these relationships. The overall pathways model explained 57.7% of the variance in dementia.

CONCLUSION

Our results suggest that physical activity, social contact and stroke were potential mediators in the relationship between age, education, employment and dementia. Intervention programmes focusing on physical activity such as exercise and social contact may be useful in reducing the risk of dementia among older adults.

Comorbid Diabetes and Depression among Older Adults - Prevalence, Correlates, Disability and Healthcare Utilisation

INTRODUCTION

The objectives of this current study were to: 1) examine the prevalence and correlates of diabetes mellitus (DM) among older adults (aged 60 years and above) in a multi-ethnic population; 2) examine the prevalence and correlates of comorbid DM and depression among them; and 3) assess the effect of comorbid depression on disability, cognition and healthcare utilisation.

MATERIALS AND METHODS

Data for the current study came from the Well-being of the Singapore Elderly (WiSE) study; a single phase, cross-sectional survey conducted among Singapore residents aged 60 years and above. A total of 2565 respondents completed the survey; depression was assessed using the Automated Geriatric Examination for Computer Assisted Taxonomy (AGECAT) while a diagnosis of DM was considered if respondents stated that a doctor had diagnosed them with DM.

RESULTS

DM was reported by 25.5% of the population. The prevalence of depression was significantly higher in those diagnosed with DM than those without DM (6% vs 3%). After adjusting for sociodemographic correlates, smoking and other chronic conditions, DM remained significantly associated with depression and subsyndromal depression. However, after including measures of functioning and cognitive impairment as covariates, DM was not significantly related to depression and subsyndromal depression. Those with comorbid DM and depression were more likely to be of Indian and Malay ethnicity, aged 75 to 84 years (versus 60 to 74 years) and widowed.

CONCLUSION

Given the significant association of certain sociodemographic groups with comorbid depression among those with DM, targeted interventions for prevention and early diagnosis in these groups should be considered.

The Societal Cost of Dementia in Singapore: Results from the WiSE Study

BACKGROUND

There is currently limited evidence on the economic burden that dementia exerts on multi-ethnic Asian populations.

OBJECTIVE

The present study aimed to estimate the economic cost of dementia in Singapore.

METHODS

We used data from the Well-being of the Singapore Elderly study, a nationally representative survey of the older Singapore Resident population aged 60 years and above. Generalized linear modeling was used to estimate factors associated with costs.

RESULTS

The total cost of dementia in 2013 was estimated at S$532 million (95% CI, S$361 million to S$701 million) while the annual cost per person was estimated at S$10,245 per year (95% CI, S$6,954 to S$12,495). Apart from dementia, higher total societal cost were also significantly associated with older age, Indian ethnicity, and those who were diagnosed with heart problems, stroke, diabetes or depression, whereas being divorced/separated, lower education, and those who were diagnosed with hypertension were significantly associated with lower total societal cost.

CONCLUSION

The study provides a rich body of information on healthcare utilization and cost of dementia, which is essential for future planning of services for the elderly population.

Gender differences in patients with first-episode psychosis in the Singapore Early Psychosis Intervention Programme

AIMS

This study aimed to identify the gender differences among multi-ethnic, Asian patients with first-episode psychosis attending the Early Psychosis Intervention Programme (EPIP) in Singapore.

METHODS

Data for this study were derived from 533 (258 female, 275 male) patients aged 16-41 years old in the EPIP database. Socio-demographic data, Positive and Negative Syndrome Scale for schizophrenia (PANSS) and Global Assessment of Functioning (GAF) scores at baseline, 3 months, 6 months and 1 year were obtained.

RESULTS

Significant gender differences were identified in terms of age, marital status, referral source, PANSS scores, GAF scores, remission and recovery over 1 year in the cohort. At service entry, female participants were older, more likely to be married and more likely to be referred from general practitioner/polyclinics (P < 0.0001). They showed better improvement over 1 year in PANSS positive, PANSS total, GAF disability and GAF total scores.

CONCLUSIONS

Overall, female participants in this sample show better improvement than male participants. They showed a better course of illness over 1 year with one-third (33.3%) of female participants achieving recovery compared with approximately a quarter (23.6%) of male participants.

Diagnosis of dementia by medical practitioners: a national study among older adults in Singapore

OBJECTIVES

Dementia is inevitably associated with an ageing population which has tremendous public health, social and economic implications. Yet the extant evidence suggests that the diagnosis of dementia in general is neither timely nor accurate. The aim of this present study was to establish the prevalence of dementia as diagnosed by medical practitioners in Singapore and its associated factors.

METHOD

The analysis is based on a national epidemiological study of older adults in Singapore which had established the prevalence of dementia using the 10/66 protocol. It was a community based survey, and face-to-face interviews were conducted with 2565 respondents (a response rate of 66%) and 2421 informants.

RESULTS

In all, 3% of the respondents were diagnosed by a medical practitioner to have dementia of which 11.5% were diagnosed by general practitioners. Only 30.3% were prescribed medications specifically for dementia. Those with comorbid depression were more likely to be diagnosed to have dementia.

CONCLUSION

The apparent low rate of diagnosis by medical practitioners is in line with studies done in the West. There is a need to elucidate the reasons underlying this under-diagnosis in order to better address this gap.

Attitudes to Mental Illness and Its Demographic Correlates among General Population in Singapore

Background

Public attitudes to mental illness could influence how the public interact with, provide opportunities for, and help people with mental illness.

Aims

This study aims to explore the underlying factors of the Attitudes to Mental Illness questionnaire among the general population in Singapore and the socio-demographic correlates of each factor.

Methods

From March 2014 to April 2015, a nation-wide cross-sectional survey on mental health literacy with 3,006 participants was conducted in Singapore.

Results

Factor analysis revealed a 4-factor structure for the Attitudes to Mental Illness questionnaire among the Singapore general population, namely social distancing, tolerance/support for community care, social restrictiveness, and prejudice and misconception. Older age, male gender, lower education and socio-economic status were associated with more negative attitudes towards the mentally ill. Chinese showed more negative attitudes than Indians and Malays (except for prejudice and misconception).

Conclusions

There is a need for culture-specific interventions, and the associated factors identified in this study should be considered for future attitude campaigns.

Validation of a Latent Construct for Dementia in a Population-Wide Dataset from Singapore

BACKGROUND

The latent variable δ has been proposed as a proxy for dementia. Previous validation studies have been conducted using convenience samples. It is currently unknown how δ performs in population-wide data.

OBJECTIVE

To validate δ in Singapore using population-wide epidemiological study data on persons aged 60 and above.

METHODS

δ was constructed using items from the Community Screening Instrument for Dementia (CSI'D) and World Health Organization Disability Assessment Schedule (WHODAS II). Confirmatory factor analysis (CFA) was conducted to examine δ model fit. Convergent validity was examined with the Clinical Dementia Rating scale (CDR) and GMS-AGECAT dementia. Divergent validity was examined with GMS-AGECAT depression.

RESULTS

The δ model demonstrated fit to the data, χ2(df) = 249.71(55), p < 0.001, CFI = 0.990, TLI = 0.997, RMSEA = 0.037. Latent variable δ was significantly associated with CDR and GMS-AGECAT dementia (range: β= 0.32 to 0.63), and was not associated with GMS-AGECAT depression. Compared to unadjusted models, δ model fit was poor when adjusted for age, gender, ethnicity, and education.

CONCLUSION

The study found some support for δ as a proxy for dementia in Singapore based on population data. Both convergent and divergent validity were established. In addition, the δ model structure appeared to be influenced by age, gender, ethnicity, and education covariates.

Prevalence and Risk Factors of Caregiver Dependence among Older Adults in a Southeast Asian Population

INTRODUCTION

Currently very little is known about the prevalence or magnitude of caregiver dependence in Singapore and thus, there is a need to fill this gap in this multiethnic ageing population. This study aims to determine the prevalence and risk factors of caregiver dependence among older adults in Singapore.

MATERIALS AND METHODS

Data were used from the Well-being of the Singapore Elderly (WiSE) study, a nationally representative, cross-sectional survey among Singapore residents aged 60 years and above. Caregiver dependence was ascertained by asking the informant (the person who knows the older person best) a series of open-ended questions about the older person's care needs.

RESULTS

The older adult sample comprised 57.1% females and the majority were aged 60 to 74 years (74.8%), while 19.5% were 75 to 84 years, and 5.7% were 85 years and above. The prevalence of caregiver dependence was 17.2% among older adults. Significant sociodemographic risk factors of caregiver dependence included older age (75 to 84 years, and 85 years and above, P <0.001), Malay and Indian ethnicity (P <0.001), those who have never been married (P = 0.048) or have no education (P = 0.035), as well as being homemakers or retired (P <0.001). After adjusting for sociodemographic variables and all health conditions in multiple logistic regression analyses, dementia (P <0.001), depression (P = 0.011), stroke (P = 0.002), eyesight problems (P = 0.003), persistent cough (P = 0.016), paralysis (P <0.001), asthma (P = 0.016) and cancer (P = 0.026) were significantly associated with caregiver dependence.

CONCLUSION

Various sociodemographic and health-related conditions were significantly associated with caregiver dependence. Dependent older adults will put greater demands on health and social services, resulting in greater healthcare expenditures. Hence, effective planning, services and support are crucial to meet the needs of dependent older adults and their caregivers.

Beliefs About Help Seeking for Mental Disorders: Findings From a Mental Health Literacy Study in Singapore

OBJECTIVE

This study investigated beliefs about help seeking, treatment options, and expected outcomes for alcohol abuse, dementia, depression, obsessive-compulsive disorder (OCD), and schizophrenia, by using a vignette-based approach.

METHODS

The Mind Matters study was a comprehensive, population-based, cross-sectional survey conducted among Singapore residents (N=3,006) ages 18 to 65 to establish the level of mental health literacy. Questions were asked about whom the person in the vignette should seek help from, the likely helpfulness of a broad range of interventions, and the likely outcome for the person in the vignette with and without appropriate help.

RESULTS

"Talk to family or friends" was the most common source of help recommended for alcohol abuse (30.1%), depression (54.2%), and schizophrenia (21.5%), and "see a doctor or general practitioner" was the most recommended for dementia (53.8%) and OCD (26.8%). Help-seeking preferences were significantly associated with age, gender, ethnicity, and income and with having a personal experience of or knowing someone with a mental disorder similar to that described in the vignette. Respondents rated seeing a psychiatrist as the most helpful intervention (88.4%) and dealing with the problem on his or her own as the most harmful (64.6%). Most respondents (79.3%) indicated that the condition of the person in the vignette would worsen if appropriate help was not sought.

CONCLUSIONS

Most respondents recommended seeking help for mental disorders from informal sources, such as family and friends. Targeted intervention strategies to improve mental health literacy related to help seeking, treatment beliefs, and effectiveness of evidence-based treatments are needed in Singapore.

Hoarding symptoms among psychiatric outpatients: confirmatory factor analysis and psychometric properties of the Saving Inventory - Revised (SI-R)

BACKGROUND

The growing interest in problematic hoarding as an independent clinical condition has led to the development of the Saving Inventory-Revised (SI-R) to assess hoarding phenomenology. The SI-R is one of the most widely used instruments to measure hoarding symptoms; however, it lacks validation in non-Western samples.

METHODS

The current study examined the construct, convergent, and discriminant validity of the SI-R among 500 outpatients at a psychiatric hospital in Singapore. The three-factor structure solution of the SI-R was fitted in a confirmatory factor analysis.

RESULTS

The final model achieved mediocre fit (χ2 = 1026.02, df = 186; RMSEA = 0.095, SRMR = 0.06; CFI = 0.86; NNFI = 0.85). Two reverse-coded items (items 2 and 4) were removed due to insufficient factor loadings, resulting in the modified 21-item SI-R (SIR-21). Our findings indicate the need to further examine the construct validity of the SI-R, particularly in non-Western samples. Nonetheless, correlations with other hoarding-related constructs, such as anxiety (Beck Anxiety Inventory) and depression (Beck Depression Inventory-II), supported the convergent and discriminant validity of the SIR-21 in our sample.

CONCLUSIONS

Findings in our current majority Chinese sample were consistent with previous observations from other Chinese samples. Implications were discussed from a cross-cultural perspective, such as cultural emphasis on saving for future use and overlap between the concepts of discarding and acquiring in Chinese samples. Future studies should also examine differences among other ethnic groups (e.g., Malay, Indian).

A systematic review on comorbid post-traumatic stress disorder in schizophrenia

Post-traumatic stress disorder (PTSD) appears to commonly co-occur with schizophrenia, which is widely considered the most disabling mental illness. Both conditions share neurological risk factors, and present with symptoms that are superficially similar, complicating diagnostic accuracy. The presence of comorbid PTSD is also of concern as additional diagnoses tend to worsen functioning and quality of life. In the current review, EMBASE, Medline, and PsycINFO were searched for articles pertaining to PTSD comorbidity in schizophrenia spectrum disorders. Articles went through two stages of review prior to inclusion - one at the abstract level and another at the full-text level. Thirty-four articles were ultimately included in the present review. Prevalence of PTSD in schizophrenia ranged from 0 to 57%, likely due to study heterogeneity. Findings generally indicated that comorbid PTSD was associated with higher levels of positive symptoms, general psychopathology, and neurocognitive impairment, as well as worse functioning and quality of life. As such, it is important for clinicians to differentiate between psychotic and PTSD symptoms, and to pay attention to the associated features of comorbid PTSD in order to provide the most appropriate intervention. Unfortunately, epidemiological and longitudinal studies in this area are lacking.

Screening for Drinking Problems in the Elderly in Singapore Using the CAGE Questionnaire

INTRODUCTION

Given that past research on drinking problems has focused primarily on younger samples, the present study sought to examine the prevalence and correlates of alcohol use among the elderly in Singapore.

MATERIALS AND METHODS

Data were extracted from the Well-being of the Singapore Elderly (WiSE) study, a cross-sectional, epidemiological survey conducted among a nationally representative sample of Singapore residents (n = 2565) aged 60 years and above. Variables assessed include drinking problems, depression and anxiety symptoms, obesity, smoking status, chronic physical disorders and disability.

RESULTS

The weighted prevalence of drinking problems (CAGE score ≥2) in our sample was 4.2%. Male sex, Indian ethnicity, and being divorced or separated were associated with a significantly higher likelihood of drinking problems. Participants with drinking problems were also more likely to have subthreshold depression. There were no significant differences in disability among those with drinking problems, those without drinking problems and non-drinkers, after adjusting for demographic variables.

CONCLUSION

Our findings contribute to the body of research that indicates an association between drinking problems and depressive symptoms among the elderly. Thus, screening for depressive symptoms in the elderly with drinking problems may be useful in identifying such comorbidities in order to aid treatment planning.

The importance of considering differential item functioning in investigating the impact of chronic conditions on health-related quality of life in a multi-ethnic Asian population

PURPOSE

The present study aims to examine the impact of chronic conditions after adjusting for differential item functioning (DIF) on the various aspects of health-related quality of life (HRQoL) in a multi-ethnic Asian population in Singapore.

METHOD

Data on 3006 participants from a nation-wide cross-sectional survey of mental health literacy conducted in Singapore were used. Multiple Indicators Multiple Causes model was used to investigate the effects of chronic medical conditions on various HRQoL dimensions assessed with the 36-item Medical Outcomes Study Short Form Health Survey (SF-36) after adjusting for DIF.

RESULTS

Twenty out of 36 items were detected with DIF for chronic conditions including high blood pressure, cardiovascular disorders, diabetes, cancer, neurological disorders and ulcer as well as for a few demographic factors such age, gender and marital status. Twenty significant associations between chronic conditions and SF-36 domains were observed. After controlling for all chronic conditions, socio-demographic and DIF items, a significant association emerged between cardiovascular disorders and physical functioning, while the association between diabetes and ulcer and general health became nonsignificant. All other associations remained statistically significant.

CONCLUSION

Our findings provide useful information and important implications of DIF on the impact of chronic conditions on HRQoL. We found the impact of DIF with respect to the impact of chronic conditions on HRQoL to be minimal after accounting for measurement bias in this multiracial Asian population.

Disrupted latent inhibition in individuals at ultra high-risk for developing psychosis

The addition of off-the-shelf cognitive measures to established prodromal criteria has resulted in limited improvement in the prediction of conversion to psychosis. Tests that assess cognitive processes central to schizophrenia might better identify those at highest risk. The latent inhibition paradigm assesses a subject's tendency to ignore irrelevant stimuli, a process integral to healthy perceptual and cognitive function that has been hypothesized to be a key deficit underlying the development of schizophrenia. In this study, 142 young people at ultra high-risk for developing psychosis and 105 controls were tested on a within-subject latent inhibition paradigm. Additionally, we later inquired about the strategy that each subject employed to complete the test, and further investigated the relationship between reported strategy and the extent of latent inhibition exhibited. Unlike controls, ultra high-risk subjects did not demonstrate a significant latent inhibition effect. This difference between groups became greater when controlling for strategy. The lack of latent inhibition effect in our ultra high-risk sample suggests that individuals at ultra high-risk for psychosis are impaired in their allocation of attentional resources based on past predictive value of repeated stimuli. This fundamental deficit in the allocation of attention may contribute to the broader array of cognitive impairments and clinical symptoms displayed by individuals at ultra high-risk for psychosis.

Gender differences in major depressive disorder: findings from the Singapore Mental Health Study

INTRODUCTION

Major depressive disorder (MDD) is one of the most common psychiatric disorders worldwide and has been associated with various sociodemographic risk factors, including age, gender and ethnicity. The present study aimed to establish whether gender-specific differences relating to the prevalence and correlates of MDD exist in the Singapore adult resident population.

METHODS

The Singapore Mental Health Study was a population-based, cross-sectional epidemiological study among Singapore citizens and permanent residents aged 18 years and above. Face-to-face interviews were completed with 6,616 respondents between December 2009 and December 2010. Psychiatric conditions were established using version 3.0 of the World Health Organization Composite International Diagnostic Interview (CIDI). In addition, data relating to chronic medical conditions was captured using a modified version of the CIDI checklist for chronic medical conditions.

RESULTS

The lifetime prevalence of MDD was higher among women (7.2%) than men (4.3%). MDD was more prevalent among men and women who were divorced/separated and widowed women, as compared to those who were single. Among men, MDD was more prevalent among Indian and other ethnicities as compared to Chinese. Of the 417 respondents with MDD, women had significantly higher odds of having generalised anxiety disorder but lower odds of having high blood pressure, as compared to men.

CONCLUSION

The study highlighted key gender-specific correlates of MDD. Given the comorbidities associated with MDD and other psychiatric disorders and/or physical illnesses, these correlates pose additional challenges for care providers.
