Although it is well established that HIV-related stigma, depression, and lack of social support are negatively associated with health-related quality of life (HRQoL) among people living with HIV (PLH), no studies to date have examined how these psychosocial factors interact with each other and affect HRQoL among incarcerated PLH. We, therefore, incorporated a moderated mediation model (MMM) to explore whether depression mediates the effect of HIV-related stigma on HRQoL as a function of the underlying level of social support. Incarcerated HIV-infected men with opioid dependence (N = 301) were recruited from the HIV units in Kajang prison in Malaysia. Participants completed surveys assessing demographic characteristics, HIV-related stigma, depression, social support, and HRQoL. Results showed that the effect of HIV-related stigma on HRQoL was mediated via depression (a1:β = 0.1463, p

Probiotics are live microorganisms that can be found in fermented foods and cultured milk, and are widely used for the preparation of infant food. They are well-known as "health friendly bacteria", which exhibit various health beneficial properties such as prevention of bowel diseases, improving the immune system, for lactose intolerance and intestinal microbial balance, exhibiting antihypercholesterolemic and antihypertensive effects, alleviation of postmenopausal disorders, and reducing traveller's diarrhoea. Recent studies have also been focused on their uses in treating skin and oral diseases. In addition to that, modulation of the gut-brain by probiotics has been suggested as a novel therapeutic solution for anxiety and depression. Thus, this review discusses on the current probiotics-based products in Malaysia, criteria for selection of probiotics, and evidences obtained from past studies on how probiotics have been used in preventing intestinal disorders via improving the immune system, acting as an antihypercholesterolemic factor, improving oral and dermal health, and performing as anti-anxiety and anti-depressive agents.

Introduction: Women are exposed to stress such as working full time while still being responsible for the family and house.
Objective: The objective of this study was to determine the prevalence of depressive symptoms among adult women in Selangor, and to determine the potential risk factors associated with depression.
Method: A community based cross sectional study was conducted in all districts of Selangor state, Malaysia in July 2004. Multi stage stratified proportionate to size sampling method was used to collect data. The Patient Health Questionnaire (PHQ-9) was used to determine the presence or absence of depressive symptoms among the respondents. All respondents aged 20 to 59 years old in the selected households were interviewed.
Results: Out of 1032 women, 972 agreed to participate in this study, giving a response rate of 94.2%. The mean age of the respondents was 37.91 ± 10.91. Majority were Malays (54.9%), married (83.8%) and had secondary education (54.5%). The results showed that the prevalence of depressive symptoms was 8.3% in Selangor. Race, religion, education level, history of having a miscarriage within the last 6 months and history of difficulty in getting pregnant were significantly associated with depressive symptoms (p<0.05). Women with history of a miscarriage within the last 6 months and absence of formal education were potential risk factors for depressive symptoms (OR, CI = 2.576 (1.165-5.696), p<0.01 and OR, CI = 5.766 (1.949-17.053), p < 0.01).
Conclusion: Depressive symptoms among adult women in Selangor was 8.3% and was associated with race, religion, education, history of miscarriage and difficulty in getting pregnant. The main potential risk factors were having a miscarriage within the last 6 months and absence of formal education.

MyJurnal

Objective: The objective of the study is to compare insight in Schizophrenia, bipolar affective disorder with psychosis and major depressive disorder with psychosis. Also to ascertain if impaired insight is associated with poorer psychosocial function. Method: 90 consecutively'admitted patients who were diagnosed with Schizophrenia, bipolar affective disorder with psychosis and major depressive disorder with psychosis were administered the scale to assess unawareness to mental illness to measure insight, the global assessment of function to measure psychosocial function and the brief psychiatric rating scale to measure psychosis.

Results: Schizophrenia was found to be associated wit h the poorest insight compared to the affective disorders. Major depression with psychosis was found to be associated with better insight than bipolar affective disorder. Results being significant in both cases. Also it was noted that there was a negative correlation between insight and psychosocial function.

Conclusion: We can conclude that Schizophrenics have the poorest insight followed by bipolar affective disorder with psychosis and then major depressive disorder with psychosis. We also infer that Schizophrenics have the poorest psychosocial function followed by bipolar affective disorder with psychosis and then major depressive disorder patients with psychosis. Also impaired insight is associated with impaired function.

Sharif SP, Lehto RH, Nia HS, Goudarzian AH, Haghdoost AA, Yaghoobzadeh A, et al.

Support Care Cancer, 2018 Aug;26(8):2571-2579.
PMID: 29450638 DOI: 10.1007/s00520-018-4088-2

PURPOSE: The study investigated relationships among the extent of disease, religious coping, and death depression in Iranian patients with cancer.
METHOD: A descriptive cross-sectional study was conducted with a convenience sample of 482 Iranian cancer patients. Participants completed demographic and health, death depression, and religious coping surveys.
RESULTS: After controlling for demographic and health characteristics, positive and negative religious coping behaviors were significantly related to the experience of death depression. There was an interaction effect between negative religious coping and extent of disease with significant positive relationships to the experience of death depression.
CONCLUSIONS: Negative religious coping was found to be more closely associated with death depression in patients with earlier stage disease than those with advanced stages of cancer in this sample of patients with cancer from Iran. Findings support assessing patients for use of religious coping strategies. Muslim patients who are religiously alienated and have existential anguish may be vulnerable and need heightened support following diagnosis and during treatment of early stage cancer.

Fulltext The Psychometric Properties of the Center for Epidemiological Studies Depression Scale (CES-D) for Iranian Cancer Patients

Sharif Nia H, Rezapour M, Allen KA, Pahlevan Sharif S, Jafari A, Torkmandi H, et al.

Asian Pac J Cancer Prev, 2019 09 01;20(9):2803-2809.
PMID: 31554380 DOI: 10.31557/APJCP.2019.20.9.2803

Objectives: The Center for Epidemiologic Studies Depression Scale (CES-D) was specifically created to assess
depression in cancer patients. However, to date, the CES-D has not been validated in Farsi. Therefore, this study aimed to
assess the psychometric properties of the CES-D in Iranian cancer patients. Methods: During a three-month period
(October to December, 2015), a total of 380 cancer patients completed a Farsi version of the CES-D. The construct
validity of the scale was evaluated by exploratory factor analysis. Reliability was assessed using Cronbach’s alpha
and McDonald Omega. All of the statistical procedure were run by SPSS 22 (SPSS Inc., Chicago, IL, USA). Results:
The construct validity of the CES-D determined three factors (somatic affect, negative affect, and positive affect),
which explained 65.60% of the total variance. The internal consistency was greater than 0.70. Conclusion: Findings
revealed that the Farsi version of the CES-D has acceptable validity and reliability, which can be used to measure
depression in Iranian cancer patients.

Sharif Nia H, Chan YH, Froelicher ES, Pahlevan Sharif S, Yaghoobzadeh A, Jafari A, et al.

Health Promot Perspect, 2019;9(2):123-130.
PMID: 31249799 DOI: 10.15171/hpp.2019.17

Background: Meteorological parameters and seasonal changes can play an important role in the occurrence of acute coronary syndrome (ACS). However, there is almost no evidence on a national level to suggest the associations between these variables and ACS in Iran. We aim to identify the meteorological parameters and seasonal changes in relationship to ACS. Methods: This retrospective cross-sectional study was conducted between 03/19/2015 to 03/18/2016 and used documents and records of patients with ACS in Mazandaran ProvinceHeart Center, Iran. The following definitive diagnostic criteria for ACS were used: (1) existence of cardiac enzymes (CK or CK-MB) above the normal range; (2) Greater than 1 mm ST-segment elevation or depression; (3) abnormal Q waves; and (4) manifestation of troponin enzyme in the blood. Data were collected daily, such as temperature (Celsius) changes, wind speed and its direction, rainfall, daily evaporation rate; number of sunny days, and relative humidity were provided by the Meteorological Organization of Iran. Results: A sample of 2,054 patients with ACS were recruited. The results indicated the highest ACS events from March to May. Generally, wind speed (18 PM) [IRR = 1.051 (95% CI: 1.019 to1.083), P=0.001], daily evaporation [IRR = 1.039 (95% CI: 1.003 to 1.077), P=0.032], daily maximum (P<0.001) and minimum (P=0.003) relative humidity was positively correlated withACS events. Also, negatively correlated variables were daily relative humidity (18 PM) [IRR =0.985 (95% CI: 0.978 to 0.992), P<0.001], and daily minimum temperature [IRR = 0.942 (95%CI: 0.927 to 0.958), P<0.001]. Conclusion: Climate changes were found to be significantly associated with ACS; especially from cold weather to hot weather in March, April and May. Further research is needed to fully understand the specific conditions and cold exposures.

Introduction: Both premature ejaculation(PE) and erectile dysfunction(ED) are prevalent sexual health disorders that have been inadequately investigated in Malaysia, a multiethnic and conservative nation.The objective of the study was to study the relationship between PE and ED, and other common mental health issues, i.e. anxiety and depression in Malaysian urban population.
Methods: The diagnosis for PE was established by clinical diagnosis using DSM-5 and ISSM definition criteria for PE, whereas a diagnosis of ED was established by the International Index of Erectile Function (IIEF) questionnaire. Anxiety and depression levels were detected from the Hospital Anxiety and Depression Scale (HADS).
Results: Based on DSM-V and ISSM clinical diagnosis for PE, the prevalence of PE was found to be 25%. Erectile dysfunction (p = 0.035, OR = 3.315, 95% CI 1.088, 10.103) and severe anxiety (p = 0.020, OR = 7.656, 95% CI 1.383, 42.396) significantly predicted presence of PE.
Conclusion: There was a strong association between PE and ED and between PE and anxiety. Routine examination for PE in male patients should address the issue and the management of both ED and anxiety among PE patients, especially in an urban Malaysian clinical and medical care setting.

The report of posttraumatic growth in Malaysian cancer patients: relationships with psychological distress and coping strategies

Schroevers MJ, Teo I

Psychooncology, 2008 Dec;17(12):1239-46.
PMID: 18457342 DOI: 10.1002/pon.1366

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.

Saravanan C, Alias A, Mohamad M

J Affect Disord, 2017 10 01;220:108-116.
PMID: 28618312 DOI: 10.1016/j.jad.2017.05.037

BACKGROUND: Students who go to other countries for higher education face various psychological problems, particularly homesickness and depression. The objectives of this study were to: (a) identify differences between students who did and did not receive brief individual cognitive behavioural therapy (CBT) for depression to reduce homesickness; (b) identify whether brief individual CBT for depression reduces the level of homesickness in students between pre-, post- and follow-up assessment; and (c) compare the scores of students experiencing only homesickness and those experiencing both homesickness and depression.
METHOD: The sample consisted of 520 first-year undergraduate international students. The experimental group contained students who were diagnosed with depression and homesickness and received seven sessions of brief individual CBT for depression to reduce homesickness. The control group contained students who were diagnosed with depression and homesickness and received one session of advice and suggestions. The comparison group contained students who experienced only homesickness and did not receive any interventions. The study used the comparison group to determine if an interaction effect existed between students experiencing only homesickness and students experiencing both homesickness and depression.
RESULTS: Students who received brief individual CBT displayed a significant reduction in their homesickness and depression scores compared to the scores of students in the control group. Students who experienced only homesickness exhibited a significant reduction in the scores on homesickness in the post-assessment compared to the control group's post-assessment homesickness scores.
LIMITATION: The results of this study cannot be generalized as data were collected from three universities in Malaysia. The follow-up assessment was conducted six months after the post-assessment, which also limits generalizability beyond six months.
CONCLUSION: Overall, homesickness is considered a normal reaction. Brief individual CBT for depression is effective in reducing homesickness and depression among international students.

Salleh MR

Acta Psychiatr Scand, 1994 Mar;89(3):180-5.
PMID: 8178676 DOI: 10.1111/j.1600-0447.1994.tb08089.x

Deinstitutionalization has shifted much of the burden of care of chronic schizophrenia from mental institutions to the family. The aim of this study is to asses the prevalence of mental disorders among 210 primary carers of Malay schizophrenic patients, explored the burden and hardship experienced by them. This is a two-stage psychiatric screening procedure. All the cases suspected from initial screening with WHO Self-Reporting Questionnaires (SRQ-20) were called for clinical interview. Patients' behavioural problems and the burden of relatives were assessed by the Social Behaviour Schedule and the Interview Schedule respectively. It was found that about 23% of the carers developed neurotic disorders resulting from the stress; nearly half of them had neurotic depression. Despite their burden, they do not complaint about it. Neurotic carers compared with non-neurotic carers had significantly more subjective burden and distress related to the product of active psychosis. The carers were generally able to tolerate the negative symptoms of schizophrenia. The number of problem behaviours and previous admissions were significantly correlated with the severity of burden.

PMID: 32013895 DOI: 10.1186/s12877-020-1444-0

BACKGROUND: Depression is one of the most common psychiatric disorders in the older adult and one of the most common risk factors for suicide in the older adult. Studies show different and inconsistent prevalence rates in Iran. This study aims to determine the prevalence of severe depression in Iranian older adult through a meta-analysis approach.
METHODS: The present meta-analysis was conducted between January 2000-August 2019. Articles related to the subject matter were obtained by searching Scopus, Sciencedirect, SID, magiran, Barakat Knowledge Network System, Medline (PubMed), and Google Scholar databases. The heterogeneity of the studies was evaluated using I2 index and the data were analyzed in Comprehensive Meta-Analysis software.
RESULTS: In a study of 3948 individuals aged 50-90 years, the overall prevalence of severe depression in Iranian older adult was 8.2% (95% CI, 4.14-6.3%) based on meta-analysis. Also, in order to investigate the effects of potential factors (sample size and year of study) on the heterogeneity of severe depression in Iranian older adult, meta-regression was used. It was reported that the prevalence of severe depression in Iranian older adult decreased with increasing sample size and increasing years of the study, which is significantly different (P

Saeidi M, Zakiei A, Komasi S

Malays J Med Sci, 2019 Jul;26(4):94-100.
PMID: 31496898 DOI: 10.21315/mjms2019.26.4.11

Background: Depression is one of the most important consequences of cardiovascular diseases (CVDs), and to control and treat it, it is necessary to identify its direct and indirect triggers and underlying factors. Therefore, the current study aims to evaluate and investigate the mediator role of aggression in the relationship between marital stress and depression.
Methods: The sample of current cross-sectional study includes 212 patients with coronary artery disease (CAD) in Iran evaluated from Jan to Jun 2017. The required data were gathered using Beck's Depression Inventory (BDI) questionnaire, Buss and Perry's Aggression Questionnaire (BPAQ), and Hudson's Marital Satisfaction Index (HMSI). The data were analysed using Pearson's correlation coefficient and structural equation modeling (SEM) using SPSS20 and AMOS software.
Results: The mean age of participants (68.4% male) was 58.5 ± 8.9. The results show that there is a significant positive relationship between all the variables (P < 0.05). The results of the model show that marital stress cannot directly predict depression (P = 0.586). However, through aggression, marital stress can significantly predict 18% of the variance of depression (P < 0.001).
Conclusions: Not directly, but indirectly through aggression, marital stress can significantly predict increased depression among patients with CAD. The physiological and psychological pathways of the findings can be discussed.

Fulltext Life satisfaction of middle-aged career women in Kelantan: the mediating role of job satisfaction

Ruzaini I, Siti Marziah Z, Wan Yusoff Wan S, See SY

Jurnal Psikologi Malaysia, 2017;31:21-28.

Job satisfaction is significantly related to overall attitudes towards life or life satisfaction. For most people, work is a central life activity. Full time employees spent substantial amount of time at work. Middle-aged women are working longer hours and spending less time with their families, which has led to family crisis, burn out, and depression. Thus, this study helps to determine the relationship between social support and family attachment on life satisfaction among middle-aged career women in Kelantan. It will also analyse the mediating role of job satisfaction. This study is a quantitative study, which was conducted in Kelantan. It involves 438 middle-aged career women in Kelantan. Social support, family attachment and job satisfaction were found to positively relate to life satisfaction. Moreover, job satisfaction was proven as the mediator in the relationship between social support and life satisfaction. This result indicates that life satisfaction of middle-aged career women rely significantly on job satisfaction. Job satisfaction can intervene the direction and the level of life satisfaction of middle-aged career women. This finding could be used as an input for any intervention programs and policies to uplift the well- being and quality of life of middle-aged women.

Archives of Orofacial Sciences, 2006;1(1):51-56.
MyJurnal

Several studies on job stress have been conducted among nurses, teachers, clerks, lecturers, laboratory technicians, petroleum and automotive workers and the calculated prevalences ranged from 20-35%; associated factors identified include high job demand, low job control and poor social support. Thus, the aim of the present study was to determine the prevalence and associated factors of stress in dental healthcare workers of an institution of higher learning in Kelantan. A cross-sectional study of the prevalence and associated factors of stress in 54 dental healthcare workers of an institution of higher learning in Kelantan [response rate of 63.5 percent] was conducted in March 2006. The Malay version of the validated Depression, Anxiety and Stress Scale and Karasek’s Job Content Questionnaire were used as research instruments in this study. Informed consents were obtained from all participants. The prevalence of stress was 22.2%. One (1.9%) staff member experienced severe stress whilst 20.4% experienced mild to moderate stress. After controlling for age, sex, marital status and duration of work, psychological job demand (adj. b 0.61, 95% CI 0.21, 1.00, p=0.003), toxic exposures (adj. b 1.41, 95% CI 0.47, 2.35, p=0.004) and overtime work (adj. b 5.67, 95% CI - 1.18, 10.16, p=0.015) were directly associated with reported stress in dental healthcare workers. High psychological job demand, increased toxic exposures at work and increased overtime work were significantly associated with stress in dental healthcare workers. These findings can be used to guide preventive measures to reduce stress in dental healthcare settings.

Fulltext Working conditions, self-perceived stress, anxiety, depression and quality of life: a structural equation modelling approach

Rusli BN, Edimansyah BA, Naing L

BMC Public Health, 2008 Feb 06;8:48.
PMID: 18254966 DOI: 10.1186/1471-2458-8-48

BACKGROUND: The relationships between working conditions [job demand, job control and social support]; stress, anxiety, and depression; and perceived quality of life factors [physical health, psychological wellbeing, social relationships and environmental conditions] were assessed using a sample of 698 male automotive assembly workers in Malaysia.
METHODS: The validated Malay version of the Job Content Questionnaire (JCQ), Depression Anxiety Stress Scales (DASS) and the World Health Organization Quality of Life-Brief (WHOQOL-BREF) were used. A structural equation modelling (SEM) analysis was applied to test the structural relationships of the model using AMOS version 6.0, with the maximum likelihood ratio as the method of estimation.
RESULTS: The results of the SEM supported the hypothesized structural model (chi2 = 22.801, df = 19, p = 0.246). The final model shows that social support (JCQ) was directly related to all 4 factors of the WHOQOL-BREF and inversely related to depression and stress (DASS). Job demand (JCQ) was directly related to stress (DASS) and inversely related to the environmental conditions (WHOQOL-BREF). Job control (JCQ) was directly related to social relationships (WHOQOL-BREF). Stress (DASS) was directly related to anxiety and depression (DASS) and inversely related to physical health, environment conditions and social relationships (WHOQOL-BREF). Anxiety (DASS) was directly related to depression (DASS) and inversely related to physical health (WHOQOL-BREF). Depression (DASS) was inversely related to the psychological wellbeing (WHOQOL-BREF). Finally, stress, anxiety and depression (DASS) mediate the relationships between job demand and social support (JCQ) to the 4 factors of WHOQOL-BREF.
CONCLUSION: These findings suggest that higher social support increases the self-reported quality of life of these workers. Higher job control increases the social relationships, whilst higher job demand increases the self-perceived stress and decreases the self-perceived quality of life related to environmental factors. The mediating role of depression, anxiety and stress on the relationship between working conditions and perceived quality of life in automotive workers should be taken into account in managing stress amongst these workers.
