    PURPOSE: To examine subjective depressive symptoms associated with physical pain symptoms (PPSs) in Asian patients with major depressive disorder (MDD).

    DESIGN AND METHODS: Four PPSs, including headache, chest pain, low back pain, and muscle pain, and subjective depressive symptoms were assessed using the Symptom Checklist-90-Revised.

    FINDINGS: Out of 528 participants, 390 (73.9%) had at least one PPS. After adjusting for sex, depression severity, disability, fatigue, physical health status, and mental health status, PPSs were found to be associated with crying easily, blaming oneself, feeling lonely, feeling blue, and worrying too much.

    PRACTICAL IMPLICATIONS: Almost three-quarters of Asian patients with MDD experience PPSs. PPSs are associated with some subjective feelings of depression.

    Importance: Depression is associated with incidence of and premature death from cardiovascular disease (CVD) and cancer in high-income countries, but it is not known whether this is true in low- and middle-income countries and in urban areas, where most people with depression now live.

    Objective: To identify any associations between depressive symptoms and incident CVD and all-cause mortality in countries at different levels of economic development and in urban and rural areas.

    Design, Setting, and Participants: This multicenter, population-based cohort study was conducted between January 2005 and June 2019 (median follow-up, 9.3 years) and included 370 urban and 314 rural communities from 21 economically diverse countries on 5 continents. Eligible participants aged 35 to 70 years were enrolled. Analysis began February 2018 and ended September 2019.

    Exposures: Four or more self-reported depressive symptoms from the Short-Form Composite International Diagnostic Interview.

    Main Outcomes and Measures: Incident CVD, all-cause mortality, and a combined measure of either incident CVD or all-cause mortality.

    Results: Of 145 862 participants, 61 235 (58%) were male and the mean (SD) age was 50.05 (9.7) years. Of those, 15 983 (11%) reported 4 or more depressive symptoms at baseline. Depression was associated with incident CVD (hazard ratio [HR], 1.14; 95% CI, 1.05-1.24), all-cause mortality (HR, 1.17; 95% CI, 1.11-1.25), the combined CVD/mortality outcome (HR, 1.18; 95% CI, 1.11-1.24), myocardial infarction (HR, 1.23; 95% CI, 1.10-1.37), and noncardiovascular death (HR, 1.21; 95% CI, 1.13-1.31) in multivariable models. The risk of the combined outcome increased progressively with number of symptoms, being highest in those with 7 symptoms (HR, 1.24; 95% CI, 1.12-1.37) and lowest with 1 symptom (HR, 1.05; 95% CI, 0.92 -1.19; P for trend

    BACKGROUND: Several studies have described the presence of perceived cognitive dysfunction amongst Asian patients with major depressive disorder (MDD). To date, no study has been conducted investigating the predictors of perceived cognitive dysfunction amongst Asian MDD patients.

    METHODS: This was a post-hoc analysis of the Cognitive Dysfunction in Asian patients with Depression (CogDAD) study. Descriptive statistics were used to describe the most common cognitive complaints by patients. Univariate and multivariate analyses were performed to determine variables associated with perceived cognitive dysfunction (Perceived Deficit Questionnaire-Depression, PDQ-D).

    RESULTS: The CogDAD study population is comprised of MDD patients with mild-to-moderate depression (Patient Health Questionnaire 9-item [PHQ-9]: 11.3 ± 6.9) who reported perceived cognitive dysfunction (PDQ-D = 22.6 ± 16.2). The most common cognitive complaints were: mind drifting (42.3%), trouble making decision (39.6%) and trouble concentrating (38.0%). Predictors of perceived cognitive dysfunction were: being Southeast Asians (vs. Taiwanese) (p

    A valid method to diagnose depression in palliative care has not been established. In this study, we aim to determine the prevalence of depression and the discriminant validity of the items of four sets of diagnostic criteria in palliative care. This is a cross-sectional study on 240 palliative care patients where the presence of depression was based on the Diagnostic and Statistical Manual of Mental Disorders, DSM⁻IV Criteria, Modified DSM⁻IV Criteria, Cavanaugh Criteria, and Endicott's Criteria's. Anxiety, depression, and distress were measured with Hospital Anxiety and Depression Scale and Distress Thermometer. The prevalence of depression among the palliative care patients was highest based on the Modified DSM⁻IV Criteria (23.3%), followed by the Endicott's Criteria (13.8%), DSM⁻IV Criteria (9.2%), and Cavanaugh Criteria (5%). There were significant differences (p < 0.05) in the depressive symptoms showed by DSM⁻IV item 1 (dysphoric mood), item 2 (loss of interest or pleasure), and Endicott's criteria item 8 (brooding, self-pity, or pessimism) among the palliative patients, even after adjustment for the anxiety symptoms and distress level. We found that dysphoric mood, loss of interest, and pessimism are the main features of depression in palliative patients. These symptoms should be given more attention in identifying depression in palliative care patients.

    There is a growing body of literature showing individuals with depression and other trauma-related disorders (e.g., posttraumatic stress disorder) recall more overgeneral and less specific autobiographical memories compared to normal participants. Although the mechanisms underlying overgeneral memory are quite clear, the search strategy operated within the autobiographical knowledge base, at time of recollection, requires further exploration. The current study aimed to examine the hierarchical search sequence used to recall autobiographical memories in depressed and non-depressed participants, with a view to determining whether depressed participants exhibited truncated search strategies.

    BACKGROUND: The heterogeneity of genetic effects on major depressive disorder (MDD) may be partly attributable to moderation of genetic effects by environment, such as exposure to childhood trauma (CT). Indeed, previous findings in two independent cohorts showed evidence for interaction between polygenic risk scores (PRSs) and CT, albeit in opposing directions. This study aims to meta-analyze MDD-PRS × CT interaction results across these two and other cohorts, while applying more accurate PRSs based on a larger discovery sample.

    METHODS: Data were combined from 3024 MDD cases and 2741 control subjects from nine cohorts contributing to the MDD Working Group of the Psychiatric Genomics Consortium. MDD-PRS were based on a discovery sample of ∼110,000 independent individuals. CT was assessed as exposure to sexual or physical abuse during childhood. In a subset of 1957 cases and 2002 control subjects, a more detailed five-domain measure additionally included emotional abuse, physical neglect, and emotional neglect.

    RESULTS: MDD was associated with the MDD-PRS (odds ratio [OR] = 1.24, p = 3.6 × 10-5, R2 = 1.18%) and with CT (OR = 2.63, p = 3.5 × 10-18 and OR = 2.62, p = 1.4 ×10-5 for the two- and five-domain measures, respectively). No interaction was found between MDD-PRS and the two-domain and five-domain CT measure (OR = 1.00, p = .89 and OR = 1.05, p = .66).

    CONCLUSIONS: No meta-analytic evidence for interaction between MDD-PRS and CT was found. This suggests that the previously reported interaction effects, although both statistically significant, can best be interpreted as chance findings. Further research is required, but this study suggests that the genetic heterogeneity of MDD is not attributable to genome-wide moderation of genetic effects by CT.

    Depression is more frequent among individuals exposed to traumatic events. Both trauma exposure and depression are heritable. However, the relationship between these traits, including the role of genetic risk factors, is complex and poorly understood. When modelling trauma exposure as an environmental influence on depression, both gene-environment correlations and gene-environment interactions have been observed. The UK Biobank concurrently assessed Major Depressive Disorder (MDD) and self-reported lifetime exposure to traumatic events in 126,522 genotyped individuals of European ancestry. We contrasted genetic influences on MDD stratified by reported trauma exposure (final sample size range: 24,094-92,957). The SNP-based heritability of MDD with reported trauma exposure (24%) was greater than MDD without reported trauma exposure (12%). Simulations showed that this is not confounded by the strong, positive genetic correlation observed between MDD and reported trauma exposure. We also observed that the genetic correlation between MDD and waist circumference was only significant in individuals reporting trauma exposure (rg = 0.24, p = 1.8 × 10-7 versus rg = -0.05, p = 0.39 in individuals not reporting trauma exposure, difference p = 2.3 × 10-4). Our results suggest that the genetic contribution to MDD is greater when reported trauma is present, and that a complex relationship exists between reported trauma exposure, body composition, and MDD.

    OBJECTIVE: To test common genetic variants for association with seasonality (seasonal changes in mood and behavior) and to investigate whether there are shared genetic risk factors between psychiatric disorders and seasonality.

    METHOD: Genome-wide association studies (GWASs) were conducted in Australian (between 1988 and 1990 and between 2010 and 2013) and Amish (between May 2010 and December 2011) samples in whom the Seasonal Pattern Assessment Questionnaire (SPAQ) had been administered, and the results were meta-analyzed in a total sample of 4,156 individuals. Genetic risk scores based on results from prior large GWAS studies of bipolar disorder, major depressive disorder (MDD), and schizophrenia were calculated to test for overlap in risk between psychiatric disorders and seasonality.

    RESULTS: The most significant association was with rs11825064 (P = 1.7 × 10⁻⁶, β = 0.64, standard error = 0.13), an intergenic single nucleotide polymorphism (SNP) found on chromosome 11. The evidence for overlap in risk factors was strongest for schizophrenia and seasonality, with the schizophrenia genetic profile scores explaining 3% of the variance in log-transformed global seasonality scores. Bipolar disorder genetic profile scores were also associated with seasonality, although at much weaker levels (minimum P value = 3.4 × 10⁻³), and no evidence for overlap in risk was detected between MDD and seasonality.

    CONCLUSIONS: Common SNPs of large effect most likely do not exist for seasonality in the populations examined. As expected, there were overlapping genetic risk factors for bipolar disorder (but not MDD) with seasonality. Unexpectedly, the risk for schizophrenia and seasonality had the largest overlap, an unprecedented finding that requires replication in other populations and has potential clinical implications considering overlapping cognitive deficits in seasonal affective disorders and schizophrenia.

    PURPOSE: Both increased as well as decreased cancer mortality among psychiatric patients has been reported, but competing death causes were not included in the analyses. This study aims to investigate whether observed cancer mortality in patients with psychiatric disorders might be biased by competing death causes.

    METHOD: In this retrospective cohort study on data from the Psychiatric Case Register Middle Netherlands linked to the death register of Statistics Netherlands, the risk of cancer death among patients with schizophrenia (N = 4,590), bipolar disorder (N = 2,077), depression (N = 15,130) and their matched controls (N = 87,405) was analyzed using a competing risk model.

    RESULTS: Compared to controls, higher hazards of cancer death were found in patients with schizophrenia (HR = 1.61, 95 % CI 1.26-2.06), bipolar disorder (HR = 1.20, 95 % CI 0.81-1.79) and depression (HR = 1.26, 95 % CI 1.10-1.44). However, the HRs of death due to suicide and other death causes were more elevated. Consequently, among those who died, the 12-year cumulative risk of cancer death was significantly lower.

    CONCLUSIONS: Our analysis shows that, compared to the general population, psychiatric patients are at higher risk of dying from cancer, provided that they survive the much more elevated risks of suicide and other death causes.

    The challenge of a cancer diagnosis may eventually lead to the experience of positive psychological changes, also referred to as posttraumatic growth. As most research on posttraumatic growth in cancer patients has been conducted in Western countries, little is known about the experience of such positive psychological changes in non-Western countries. Therefore, the purpose of this cross-sectional study was to investigate the prevalence of posttraumatic growth in a Malaysian sample of cancer patients. Secondly, we examined the association of posttraumatic growth with patients' report of psychological distress and their use of coping strategies.

    PURPOSE: To examine correlates of disability in Asian patients with major depressive disorder (MDD).
    DESIGN AND METHODS: Participants were outpatients with DSM-IV MDD. Global disability and three disability domains (i.e., work/school, social life/leisure, and family/home life) were key outcomes. Several socio-demographic and clinical characteristics were determined for their associations with disability.
    FINDINGS: The sample was 493 MDD patients. Apart from the number of hospitalizations, the global disability was significantly associated with depression severity, fatigue, physical health, and mental health. Several clinical but only few socio-demographic characteristics associated with the other three disability domains were similar.
    PRACTICE IMPLICATIONS: Disability among Asian patients with MDD correlates with the severity of psychiatric symptoms and the hospitalizations due to depression. Socio-demographic characteristics have little impact on the overall disability.

    BACKGROUND: Breast cancer is one of the most feared diseases among women and it could induce the development of psychological disorders like anxiety and depression. An assessment was here performed of the status and to determine contributory factors.

    MATERIALS AND METHODS: A cross-sectional study was conducted among breast cancer patients at University Kebangsaan Malaysia Medical Center (UKMMC), Kuala Lumpur. A total of 205 patients who were diagnosed between 2007 until 2010 were interviewed using the questionnaires of Hospital Anxiety and Depression (HADS). The associated factors investigated concerned socio-demographics, socio economic background and the cancer status. Descriptive analysis, chi-squared tests and logistic regression were used for the statistical test analysis.

    RESULTS: The prevalence of anxiety was 31.7% (n=65 ) and of depression was 22.0% (n=45) among the breast cancer patients. Age group (p= 0.032), monthly income (p=0.015) and number of visits per month (p=0.007) were significantly associated with anxiety. For depression, marital status (p=0.012), accompanying person (p=0.041), financial support (p-0.007) and felt burden (p=0.038) were significantly associated. In binary logistic regression, those in the younger age group were low monthly income were 2 times more likely to be associated with anxiety. Having less financial support and being single were 3 and 4 times more likely to be associated with depression.

    CONCLUSIONS: In management of breast cancer patients, more care or support should be given to the young and low socio economic status as they are at high risk of anxiety and depression.

    Objectives: The Brief Ageing Perceptions Questionnaire (B-APQ) has five domains that explore views about own ageing. The aim of this study was to validate the B-APQ for use among older adults in Malaysia and to explore socio-demographic variations in ageing self-perceptions.Method: Older adults aged 50 years and above were randomly selected to complete a set of questionnaires. Cronbach's α was used to measure internal consistency, while corrected item-total correlations and correlation with DASS-21 and the CASP-19 scores were employed to assess convergent and discriminant validity. Confirmatory Factor Analysis (CFA) was conducted to confirm the factorial structure of the B-APQ. Difference in self-perceptions of ageing across socio-demographic variables was assessed.Results: Internal consistency for each of the domains was good. Item-total correlations within each domain were strong (>0.6) or very strong (>0.8). Convergent and discriminant validity were supported by significant correlations with DASS-21 depression and CASP-19 scores. CFA results indicated good model fit with the original B-APQ model. Presence of chronic illness also has a significant impact on B-APQ domain scores.Conclusion: The B-APQ is a valid and reliable instrument which can be used to assess self-perceptions of ageing among older Malaysian adults.

    Dementia is a neurocognitive disorder that affects a person's abilities in daily functioning. Anxiety and depression symptoms are common among persons with dementia. Cognitive behavioural therapy (CBT) has been tested to manage their depression and anxiety symptoms. However, the purpose of CBT in managing these symptoms is unclear. Therefore, this paper aims to clarify whether CBT can be used to reduce depression and anxiety symptoms in persons with dementia. The electronic databases PubMed, PsycINFO, MEDLINE, and CINAHL were used to locate relevant studies. Eleven studies, which involved a total of 116 older adults, were identified. The findings suggest that CBT can be effective in reducing depression and anxiety symptoms. Based on our current review, the findings from previous studies form a promising foundation on which to conduct a major randomized controlled trial with a larger sample size. This review discusses some of the most important considerations in applying CBT to persons with dementia, and these may be beneficial for future studies that explore this area and seek more conclusive evidence on the use of CBT.

    Objectives: This study investigated the outcomes that an interview-based medical school admission process has on academic performance, psychological health, personality traits, and emotional intelligence.

    Methods: A comparative cross-sectional study was conducted on the interviewed and non-interviewed cohorts. Their examination marks were obtained from the academic office, psychological health was measured by DASS-21, personality traits were measured by USMaP-15, and emotional intelligence was measured by USMEQ-17.

    Results: The interviewed cohort performed significantly better in the clinical examination than the non-interviewed cohort. Conversely, the non-interviewed cohort performed significantly better in the theoretical examination. Depression, anxiety, and stress level between the two cohorts showed no difference. The interviewed cohort demonstrated more desirable personality traits, higher emotional intelligence, and social competence than the non-interviewed cohort.

    Discussion: This study provides evidence to support the claim that the interview-based admission process has favourable outcomes on clinical performance, emotional intelligence, and personality traits. Several insights gained as a result of this study are discussed.

    Introduction: School refusal is a common cause of chronically poor school attendance. The basis of school refusal behaviour can be grouped into the symptomatic and functional models, the operant conditioning model and the cognitive model. Objective: This paper is aimed to discuss the various systems and models which explain the school refusal behaviour. Method: An initial search of published literature in English Language was performed on the online databases including Google Scholar, Science Direct, EBSCOhost, and Proquest with the main keywords were School Refusal and Self–efficacy. Further sources were identified after consulting the original author for recommendations, and references within the literature retrieved in the initial search. Results: Out of 57 articles found, 41 were used in this review. Development and maintenance of school refusal involve heterogeneous risk factors and processes. The existing theoretical basis of school refusal behaviour can be grouped into symptomatic models, the operant conditioning model and the cognitive model. Conclusion: School refusal depicts a symptom, heralding the need for early intervention before development of a more pervasive mental health disorder. Where the problem had persisted for months to years, the child or adolescent would commonly present with coexisting anxiety or depressive disorders.

    The Beck Depression Inventory (BDI) has been shown to have good psychometric properties in Western and non-Western populations for the past 40 years. The present study reported on the factor structures and provided evidence of the psychometric properties of the BDI for the Malays in Malaysia. A total of 1090 Malays in four samples (students, general community, general medical patients, and patients with major depressive disorders) were recruited in this study. They completed a battery of questionnaires that included symptoms, cognition and quality of life measures. Two factors of the BDI-Malay namely Cognitive/Affective and Somatic/Vegetative were extracted from Exploratory Factor Analysis (EFA) and were confirmed through Confirmatory Factor Analysis (CFA). Internal consistency (Cronbach's ) ranging from = .71 to .91 and validity of the BDI-Malay were satisfactory. The BDI-Malay can be used with confidence as an instrument to measure levels of depression for Malays in Malaysia.

    Major depressive disorder (MDD) is a serious mental illness with a multifactorial aetiology that was shown to influence behaviour and affect cognition. Previous research has favoured the involvement of dopamine in the aetiology of the disorder, and since one of the critical regulators of the dopamine levels and activity in the brain is DAT1, the present study investigated the association of a single nucleotide polymorphism in the DAT1gene (rs40184) and MDD in the Malaysian population. A total of 300cases and 300 matched controls were recruited from four Klang valley hospitals and were screened for DAT1rs40184 using high resolution melting assays. The allele and genotype frequencies were analysed by using Chi-square. Hardy Weinberg equilibrium for the distribution of alleles and genotypes was tested by using Chi-square. Determination of the association between rs40184 and MDD was achieved by conditional logistic regression using SPSS. In the present study, no significant association was obtained between DAT1and MDD in the Malaysianpopulation.
