Systematic review and meta-analysis of internalised stigma and stigma resistance in patients with psychosis: The impact of individualism-collectivism culture and other individual factors.

PURPOSE: This study aimed to meta-analysis the level of internalised stigma experienced by individuals with psychosis worldwide, and the impact of cultural differences, economic status of the studied regions and duration of illness on their levels of internalised stigma. Clinical and individual level factors associated with internalised stigma and stigma resistance were also systematically reviewed. METHODS: A systematic search of keywords on two scholarly databases were conducted. The individualism index of the countries or regions where the studies were conducted was retrieved from Hofstede's updated measurement of individualism. Economic status of regions was categorised based on their per capita gross national income. Meta-analysis and meta-regression were conducted using the 'metafor' package in R. Factors associated with internalised stigma and stigma resistance were also systematically consolidated. RESULTS: Seventy-three articles were included in the meta-analysis and the pooled score of both internalised stigma and stigma resistance of individuals with psychosis were within the mild range (2.20 and 2.44, respectively). The meta-regression analysis found high collectivism culture is significantly related to a higher level of internalised stigma. Economic status was not significant. Thirty-five articles were included in the systematic review and clinical, psychological, psychosocial variables, cognition and sociodemographic factors were found to be associated with internalised stigma. CONCLUSION: Internalised stigma in psychosis is ubiquitous worldwide and high collectivism culture may be related with high internalised stigma. With the presence of multiple individual factors related to internalised stigma, intervention programmes to reduce internalised stigma should consider focussing on both macro- and micro-level factors.

Stigma towards mental illness, resilience, and help-seeking behaviours in undergraduate students in Hong Kong.

AIM: Early interventions have great impact on reducing burden of mental illness. Young people are however the least likely to seek help for psychological issues. Resilience and stigma towards mental illness have been identified as contributing factors, although previous findings were mixed with potentially complex interaction with symptom severity. We investigated the relationship between stigma, resilience, depressive symptom severity, and help-seeking behaviours in undergraduate students in Hong Kong. METHODS: A cross-sectional online survey was conducted among undergraduates from a university in Hong Kong (n = 945). The 21-item Stigma and Acceptance Scale, Connor-Davidson Resilience Scale, and the Patient Health Questionnaire-9 were used. History of help-seeking for psychological issues was self-reported. Path analysis was conducted to test a conceptual model of their relationships. RESULTS: Among those with moderate-to-severe depressive symptoms (39.5%), only one-fourth had sought professional help. The path model showed that depressive symptom severity and stigma were positively associated with help-seeking behaviours, while resilience was negatively associated with help-seeking behaviours independently (all p < .001). Subgroup analyses showed differential contribution of stigma and resilience to a history of help-seeking in those with minimal-to-mild symptoms compared with moderate-to-severe symptoms. CONCLUSIONS: Stigma may be a barrier for help-seeking particularly in students with moderate-to-severe depression. Higher levels of resilience in young people may be protective and reduce the unnecessary seeking of professional help. Therefore, enhancing resilience among students in general, and reducing stigma and promoting help-seeking behaviours for those who have moderate-to-severe symptoms should be consider in parallel as strategies to enhance mental wellbeing of students.

The role of education level on changes in endorsement of medication treatment and perceived public stigma towards psychosis in Hong Kong: comparison of three population-based surveys between 2009 and 2018.

OBJECTIVE: This study aimed to investigate the changes in perceived public stigma (PPS) towards psychosis, and endorsement of medication treatment between 2009 to 2018 in the Hong Kong Chinese population.The role of education level on the changes in PPS and endorsement of medication treatment for psychosis was also examined. METHODS: Telephone survey of the general population was conducted in 2009, 2014, and 2018. PPS was assessed using the revised Link's Perceived Discrimination-Devaluation Scale. Endorsement of medication was measured using an item asking if individuals with psychosis requires medication to manage their symptoms. Education level was separated into three categories (primary, secondary, and tertiary) for analysis. Factorial analysis of covariance was used to examine the main effects of survey year, education and endorsement of medication on stigma, and the interaction between survey year and education level, and survey year and endorsement of medication on PPS. RESULTS: 1016, 1018, and 1514 respondents completed the surveys in 2009, 2014, and 2018, respectively. PPS was found to be stable across the three public surveys. Endorsement of medication treatment was associated with higher PPS. An interaction effect between survey year and education level onPPS was observed. PPS was significantly lower and fewer respondents endorsed medication treatment in 2018 in the tertiary education group than in previous years. CONCLUSION: Current findings suggest that a targeted approach may be required for different education groups when developing anti-stigma public campaigns. Inclusion of other aspects of knowledge about psychosis may also be useful in reduction of PPS.

Elucidating the relationship between internalized stigma, cognitive insight, illness severity, and functioning in patients with schizophrenia using a path analysis approach.

BACKGROUND: There is a paucity of studies examining the interrelationship between internalized stigma, cognitive insight, illness severity, and functioning. AIMS: This study examined the dynamics of the relationship between these factors using a path modelling approach. METHODS: Two hundred and seven patients with schizophrenia spectrum disorders were recruited in this cross-sectional study. Patients were assessed on internalized stigma, cognitive insight (including its two domains, self-reflectiveness and self-certainty), illness severity and functioning. Path analysis was used to test the hypothesized model for the interrelationship between the variables. RESULTS: A direct positive association was observed between self-certainty and internalized stigma. This was also observed via the paths running through illness severity and functioning. Self-reflectiveness was only associated with self-certainty in the model. The residual variance of internalized stigma in the path model was relatively high. CONCLUSION: Our findings highlight that self-certainty is associated with internalized stigma along with illness severity and functioning in individuals with schizophrenia. Therefore, interventions on reduction of internalized stigma may benefit from a multipronged approach targeting self-certainty, illness severity and functioning. The relatively high residual variance of internalized stigma in the model highlights the need for further research to provide better understanding on the mechanisms underlying internalized stigma.

Inter-relationships between perception of educational environment and learning processes within medical undergraduate psychiatry teaching: a mediational analysis.

Amongst medical undergraduates, the perception of educational environment (EE) has been associated with academic achievement and positive attitude toward the course. Nonetheless, there are sparse data on how it influences various learning processes and outcomes especially within psychiatry training. Consistent with situativity and self-determination learning theories, we hypothesized that a positive perception of the EE within psychiatry postings will be beneficial for the learning process, specifically pertaining to greater motivation to learn, better engagement, allowing them to feel more equipped, and greater appreciation of the subject. The DREEM (Dundee Ready Education Environment Measure) was administered to fourth-year medical undergraduate students from the Yong Loo Lin School of Medicine, Singapore, undergoing psychiatry rotations from 2015 to 2019. The students also completed five additional items evaluating the specific learning processes (motivation to learn, engagement, equipping, and appreciation of the subject) and overall rating of the posting. We examined the relationship between DREEM domains and learning processes using correlation analysis. We explored learning processes as mediators of the relationship between total DREEM scores and overall rating of the posting. Altogether, 1343 (response rate 89.5%) medical undergraduates participated in the study. The overall DREEM score was 157.01 ± 15.86. Overall DREEM and subdomain scores were significantly correlated with several learning processes (r = 0.354 to 0.558, all p < .001). Motivation and engagement were significant mediators of the relationship between total DREEM scores and overall rating of the psychiatry posting. Our results highlighted that a positive perception of EE was associated with the specific learning processes that mediated the overall rating of the posting. In the context of relevant learning theories and our study findings, improvement of the EE within undergraduate psychiatry training can potentially enhance overall learning experience through better motivation and engagement of our learners.

Sociodemographic correlates of public stigma about mental illness: a population study on Hong Kong's Chinese population.

BACKGROUND: Individuals with psychiatric disorders are often unwilling to seek help or often follow treatment regimens, fearing public stigma. This study identified the sociodemographic correlates of public stigma while accounting for mental health literacy and life satisfaction. METHODS: This study analysed data for 1514 individuals who participated in a population-based random telephone survey conducted in 2018. Sociodemographic characteristics included gender, age, education level, and occupation. Data on public stigma, mental health literacy, and life satisfaction were also collected. Multiple linear regression was conducted to examine the effects of sociodemographic characteristics on public stigma. A moderation analysis was performed to investigate the role of age and education in the relationship between mental health literacy and public stigma. RESULTS: Sociodemographic characteristics, such as female gender, older age, lower education, and occupation (particularly retired and homemakers), were associated with a higher public stigma. The association between public stigma and mental health literacy was the most significant among individuals aged 50 years and above with lower education levels. CONCLUSIONS: This study showed that certain population subgroups, based on their sociodemographic profile, have a higher stigma about mental illnesses. Understanding the differential effects of sociodemographic factors on public stigma is imperative to developing effective anti-stigma campaigns.

Internalized stigma as an independent predictor of employment status in patients with schizophrenia.

OBJECTIVE: This study aimed to clarify the relationship between employment status and internalized stigma in patients with schizophrenia in Hong Kong. METHODS: One hundred and seventy-nine patients with schizophrenia were included in this study. The employed group included patients with full- or part-time open employment and full-time students. The unemployed group included those attending rehabilitation services and those unemployed. Internalized stigma was assessed using the Internalized Stigma of Mental Illness scale, consisting of alienation, stereotype endorsement, discrimination experience, social withdrawal, and stigma resistance domains. The relationship between these domains and employment status was assessed using logistic regression. FINDINGS: Fifty-seven percent of participants were employed. Employment status was positively associated with stigma resistance and negatively associated with stereotype endorsement, but not with total internalized stigma. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Findings suggest that future interventions can focus on increasing stigma resistance and reducing stereotype endorsement to improve vocational outcomes in patients with schizophrenia.

Relationship between subjective quality of life and perceptions of recovery orientation of treatment service in patients with schizophrenia and major depressive disorder.

OBJECTIVE: This study aimed to investigate the relationship between subjective quality of life (QOL) and the specific domains of perceptions of recovery orientation of treatment services in patients with schizophrenia and major depressive disorder (MDD). METHODS: One hundred and seventy-nine patients with schizophrenia spectrum disorders and fifty-seven patients with MDD were recruited. Patients were assessed on subjective QOL, self-reported depressive symptoms, illness severity, functioning, and perception of recovery orientation of the service environment (RSA). A multiple linear regression model was used to assess the relationship between QOL and RSA score, controlling for all other factors. Spearman correlation analysis was used to examine the relationship between RSA domains and total QOL in each diagnostic group separately. RESULTS: The regression model explained 47.4 % of the variance observed in total QOL. Depressive symptoms, functioning and RSA were significantly associated with total QOL in the model. Domains one (life goals) and five (individually tailored services) of the RSA were associated with QOL in both groups. Domains two (patient involvement) and three (diversity of treatment options) were associated with total QOL only in patients with schizophrenia. CONCLUSION: Our findings highlight that perceptions of recovery orientation of service, depressive symptoms and functioning significantly affected the subjective QOL of patients with serious mental illness. The differential relationship observed between QOL and domains of RSA in patients with MDD and schizophrenia suggests that targeted interventions meeting the needs of different patient groups may be crucial to improve QOL of patients.

Systematic review of the use of debates in health professions education - does it work?

Background: It is unavoidable for learners undergoing health professions training to encounter different complex clinical scenarios related to diagnoses, treatment and ethical dilemmas. The lack of standard answers to such clinical challenges can cause uncertainty in the process of teaching, learning and assessment as learners grapple with the need to critically appraise the specific context, past practices and extant literature to arrive at a thoughtful decision. In this aspect, debate can be a useful pedagogical tool to consider multiple, different perspectives regarding these issues. As the use of debate within the health professions education has not been reviewed, we conducted a systematic review of the current literature on the adoption of debate as a pedagogical tool to clarify the specific context of use as well as its effectiveness in the learning of skills and content within the health professions education. Methods: A systematic review was conducted on relevant published literature in English within journal databases until September 2018 that employed debate as a pedagogical tool within health professions education. Results: Out of 626 screened articles, 12 studies were finally included based on inclusion/exclusion criteria. The 12 studies (9 undergraduate, 3 postgraduate) covered a diverse range of disciplines and debate in health professions education was adopted for acquisition of skills (such as critical thinking, communication skills, teamwork), or learning of specific topics (such as patient safety, ethical issues, teaching of new topics) as well as to examine evidence based practice. In the majority of studies (10 of 12 studies, 83.3%), debate has been deemed by the learners to be effective in facilitating the learning of new content and skills such as communication and critical thinking, which are related to processes aligned with adult learning, motivational, reflective and social learning theories. Conclusion: Overall, sparse studies to date with relatively low risk of bias found debate to be effective in enabling the learning of skills and content within health professions education. Future studies may want to incorporate more objective measures of the learning outcomes of learners following the adoption of debate as a teaching tool as well as to examine the combinatorial use of debate with other pedagogical tools and their longitudinal impact on learners and learning.

Perceptions of the Learning Environment on the Relationship Between Stress and Burnout for Residents in an ACGME-I Accredited National Psychiatry Residency Program.

BACKGROUND: High rates of burnout have been reported in physicians in training, with contributing factors including stress, lack of coping skills, and attributes of the learning environment. The interrelationships among these factors and how they affect versus mitigate burnout in an international cohort of residents have not been studied. OBJECTIVE: We examined the interrelationships between stress, perceptions of the learning environment, and coping strategies used in a cohort of psychiatry residents in Singapore, using burnout as the dependent variable. We hypothesized that perceptions of the learning environment and coping strategies influence the relationship between residency-related stress and burnout in psychiatry residents. METHODS: From June 2016 to September 2017, 67 of 75 (89%) psychiatry residents from a single program in Singapore were assessed on their levels of stress and burnout, perceptions of their learning environment (including role autonomy, teaching, and social support), and the coping mechanisms they used. RESULTS: Psychiatry residents in this Singaporean program perceived their overall learning environment to be positive. Perceptions of the learning environment, not coping strategies, significantly mediated the relationship between stress and burnout. CONCLUSIONS: Findings from this study suggest that perceptions of the learning environment mediate the relationship between stress and burnout. Approaches to evaluate and improve resident perceptions of aspects of their learning environment may be an effective strategy to manage burnout in psychiatry residency programs.

General anesthesia / sedation requirement influences the way MRI brain scans are ordered in a tertiary pediatric hospital.

BACKGROUND: MRI guidelines have been created to help clinicians order scans appropriately. Some scans in children are carried out under general anesthesia (GA) / sedation. PURPOSE: To evaluate if the requirement for GA/sedation influences the way MRI brain scans are ordered. STUDY TYPE: Retrospective. POPULATION: Children with MRI brain scans in 2015 to 2017. FIELD STRENGTH: 3T, 1.5T. ASSESSMENT: Institutional Review Board approval for waiver of consent was obtained. Clinical MRI brain reports for children were classified into whether they conformed to the American College of Radiology (ACR) 2013 guidelines by research assistants under supervision of a pediatric radiologist. Scans were sorted into those with normal brains or abnormality. STATISTICAL TEST: The statistical difference between groups was assessed using t-test for continuous variables and chi-square test for categorical variables with IBM SPSS 19. RESULTS: Of the total 1893 MRI scans, 431 were performed under GA and six under sedation. Of the 431 cases performed under GA/sedation, 383 (87.6%) were ordered according to guidelines. Of the 1456 cases that did not require GA/sedation, 710 (48.8%) conformed to guidelines. The percentage of scans ordered according to guidelines was 38.8% higher in those who had scans performed under GA/sedation (P < 0.001). MRI scans were normal in 635 (58.0%) out of the 1093 cases ordered according to guidelines and normal in 638 (79.8%) out of the 800 cases that did not follow guidelines. Scans not ordered according to guidelines had higher proportion of normal scans (21.8%) compared with those ordered according to guidelines (P < 0.001). DATA CONCLUSION: Higher adherence to imaging guidelines is seen in younger patients who were exposed to the risks of GA/sedation for the MRI. Scans not adhering to guidelines had a higher percentage of having no brain abnormality detected. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 6 J. Magn. Reson. Imaging 2019;49:e250-e255.

Randomized Controlled Trials of Psychoeducation Modalities in the Management of Bipolar Disorder: A Systematic Review.

OBJECTIVE: This review sought to summarize the extant literature on the efficacy of 4 modalities of psychoeducation (individual, group, family, internet- based) in the management of patients with bipolar disorder. DATA SOURCES: We searched the digital databases (Science Direct, Scopus, PubMed/MEDLINE) for relevant randomized controlled trials (RCTs) pertaining to psychoeducation in bipolar disorder from inception to February 2017. Keywords and combinations used included psychoeducation, bipolar disorder, individual, family, group, and internet. Reference lists of review articles were also used for retrieval of relevant articles. STUDY SELECTION: We retrieved 48 studies and ultimately reviewed 40 RCTs meeting inclusion criteria. Studies were included if they were in English, were RCTs of different psychoeducation modalities managing patients with bipolar disorder, and used standardized assessment of outcomes of psychoeducation. DATA EXTRACTION: We examined each of the selected publications for relevant data. RESULTS: The majority of psychoeducation RCTs (28 of 40 studies, 70.0%) focused on group and family psychoeducation, with positive benefits reported in clinical outcomes, treatment, and functioning measures. Group psychoeducation was associated with reduced illness recurrences, decreased number and duration of hospitalizations, increased time to illness relapse, better treatment adherence, higher therapeutic lithium levels, and reduced stigma. Family psychoeducation was associated with reductions in illness recurrence, hospitalization rates, and better illness trajectory as well as increased caregiver knowledge, skills, support, and sense of well-being and reduced caregiver burden. There are fewer RCTs on individual and internet-based psychoeducation, with findings being inconsistent or negative. CONCLUSIONS: Future studies may include direct comparisons of different psychoeducation modalities to elucidate specific benefits of unique psychoeducation interventions at different phases of bipolar disorder.

Neurocognitive functioning and quality of life in patients with and without deficit syndrome of schizophrenia.

Deficit syndrome of schizophrenia is a subtype of schizophrenia characterized by primary and enduring negative symptoms. This study examined the differences in neurocognitive functioning and quality of life (QOL) between deficit and non-deficit patients, and specific predictors of both clinical measures. Overall, 344 subjects (175 patients with non-deficit schizophrenia (NDSZ), 58 patients with deficit schizophrenia (DSZ) and 111 healthy controls) were evaluated on severity of psychopathology, QOL and a smaller subset of 198 subjects (104 NDSZ, 27 DSZ, 67 healthy controls) underwent neurocognitive assessments. Multivariate analyses were used to determine differences in outcomes between subject groups and predictors of clinical measures. Both DSZ and NDSZ had significantly worse QOL compared with healthy controls. DSZ had more extensive cognitive deficits compared with healthy controls and performed worse on semantic fluency task compared to NDSZ. Multiple linear regression analysis found that DSZ, shorter duration of illness were associated with poorer QOL whereas fewer years of education, lower premorbid intelligence were associated with poorer overall neurocognitive functioning. The poorer QOL, greater extent of neurocognitive deficits especially semantic fluency associated with DSZ behoves the need for greater attention during clinical evaluation and treatment planning of this subgroup of individuals with schizophrenia.

Adoption and correlates of the Dundee Ready Educational Environment Measure (DREEM) in the evaluation of undergraduate learning environments - a systematic review.

BACKGROUND: The Dundee Ready Educational Environment Measure (DREEM) was specifically designed to measure the undergraduate medical educational environment. This study seeks to review the adoption of DREEM internationally, and its association with different learning contexts and learner factors in order to better support our learners and facilitate future applications and research. METHOD: A systematic literature review was conducted on all articles that adopted and reported data using the DREEM from 1997 to April 2017. RESULTS: Overall, the majority of 106 included studies from over 30 countries were conducted in Asia and Europe (76.4% of studies) within medical, dental, and nursing programs (86.8% of studies). Seventy-nine out of 98 studies (80.6%) which reported DREEM scores observed a mean total DREEM score within the range of "more positive than negative" (101-150 out of maximum 200 points). Higher DREEM scores were associated with better past academic achievement, quality of life, resilience, positive attitudes towards course, mindfulness, preparedness for practice, less psychological distress, and greater peer support. CONCLUSIONS: Future studies may want to examine other correlates of DREEM such as coping styles, personality profiles, burnout level, and DREEM scores can be incorporated into reviews of learning environments to ascertain longitudinal changes following educational interventions.

Elucidation of shared and specific white matter findings underlying psychopathology clusters in schizophrenia.

BACKGROUND: Schizophrenia is associated with diverse white matter (WM) brain abnormalities. In this study, we sought to examine the WM microstructural findings which underlie clinical psychopathology clusters in schizophrenia and hypothesized that these symptom clusters are associated with common and unique WM tracts. METHODS: Overall, 76 healthy controls (HC), and 148 patients with schizophrenia (SZ) were recruited and severity of symptomatology in schizophrenia was assessed using the Positive and Negative Syndrome Scale. WM fractional anisotropy (FA) values were extracted from their diffusion tensor images. Psychopathology clusters were first determined using factor analysis and the relationship between these symptom factors and FA values were then assessed with structural equation modelling, which included covariates such as age, sex, duration of illness and medications prescribed. RESULTS: Patients with schizophrenia had reduced FA in the genu of corpus callosum (gCC) compared to HC. A three-factor model, namely Positive, Negative, Disorganised factors, was determined as the best fit for the data. All three psychopathology factors were associated with decreased FA in the gCC and bilateral cingulate gyrus. Higher Negative factor scores were uniquely associated with decreased FA in the right sagittal striatum and right superior longitudinal fasciculus. CONCLUSIONS: This study found shared and specific WM changes and their associations with specific symptom clusters, which potentially allows for monitoring of such white matter findings associated with clinical presentations in schizophrenia over treatment and illness course.

Clinical Use of Mood Stabilizers With Antidepressants in Asia: Report From the Research on Asian Psychotropic Prescription Patterns for Antidepressants (REAP-AD) Projects in 2004 and 2013.

OBJECTIVE: As most reports concerning treatment with combinations of mood stabilizer (MS) with antidepressant (AD) drugs are based in the West, we surveyed characteristics of such cotreatment in 42 sites caring for the mentally ill in 10 Asian countries. METHODS: This cross-sectional, pharmacoepidemiologic study used 2004 and 2013 data from the REAP-AD (Research Study on Asian Psychotropic Prescription Patterns for Antidepressants) to evaluate the rates and doses of MSs given with ADs and associated factors in 4164 psychiatric patients, using standard bivariate methods followed by multivariable logistic regression modeling. RESULTS: Use of MS + AD increased by 104% (5.5% to 11.2%) between 2004 and 2013 and was much more associated with diagnosis of bipolar disorder than major depression or anxiety disorder, as well as with hospitalization > outpatient care, psychiatric > general-medical programs, and young age (all P < 0.001), but not with country, sex, or AD dose. CONCLUSIONS: The findings provide a broad picture of contemporary use of MSs with ADs in Asia, support predictions that such treatment increased in recent years, and was associated with diagnosis of bipolar disorder, treatment in inpatient and psychiatric settings, and younger age.

Hemispheric lateralization abnormalities of the white matter microstructure in patients with schizophrenia and bipolar disorder.

BACKGROUND: Hemispheric lateralization of the brain occurs during development and underpins specialized functions. It is posited that aberrant neurodevelopment leads to abnormal brain lateralization in individuals with psychotic illnesses. Here, we sought to examine whether white matter hemispheric lateralization is abnormal in individuals with the psychotic spectrum disorders of schizophrenia and bipolar disorder. METHODS: We examined the white matter microstructure lateralization in patients with schizophrenia, bipolar disorder with psychotic features and healthy controls by measuring the laterality indices of fractional anisotropy (FA) and mean diffusivity (MD). We also correlated the laterality indices with clinical measures. RESULTS: We included 150 patients with schizophrenia, 35 with bipolar disorder and 77 healthy controls in our analyses. Shared FA lateralization abnormalities in patients with schizophrenia and bipolar disorder were found in the cerebral peduncle and posterior limb of internal capsule, with more extensive abnormalities in patients with bipolar disorder than in those with schizophrenia. The shared MD lateralization abnormalities were more widespread, extending to the subcortical, frontal-occipital, limbic and callosal tracts, with patients with bipolar disorder showing greater abnormalities than patients with schizophrenia. While lateralization was decreased in patients with schizophrenia, the lateralization was reversed in those with bipolar disorder, underpinned by the more pronounced microstructural abnormalities in the right hemisphere. The loss of FA lateralization in patients with schizophrenia was associated with lower quality of life and psychosocial functioning. LIMITATIONS: Owing to the cross-sectional study design, we cannot confirm whether the lateralization abnormalities are neurodevelopmental or a consequence of psychosis onset or chronicity. CONCLUSION: Shared and distinct white matter lateralization abnormalities were found in patients with schizophrenia and bipolar disorder. In distinct regions of abnormalities, the lateralization was attenuated in patients with schizophrenia and reversed in those with bipolar disorder.

Factors Associated With Antidepressant Dosing in Asia: Findings From the Research on Asian Psychotropic Prescription Study.

In this study, we sought to examine factors associated with dosing of antidepressants (ADs) in Asia. Based on reported data and clinical experience, we hypothesized that doses of ADs would be associated with demographic and clinical factors and would increase over time. This cross-sectional, pharmacoepidemiological study analyzed data collected within the Research Study on Asian Psychotropic Prescription Pattern for Antidepressants from 4164 participants in 10 Asian countries, using univariate and multivariate methods. The AD doses varied by twofold among countries (highest in PR China and RO Korea, lowest in Singapore and Indonesia), and averaged 124 (120-129) mg/d imipramine-equivalents. Average daily doses increased by 12% between 2004 and 2013. Doses were significantly higher among hospitalized patients and ranked by diagnosis: major depression > anxiety disorders > bipolar disorder, but were not associated with private/public or psychiatric/general-medical settings, nor with age, sex, or cotreatment with a mood stabilizer. In multivariate modeling, AD-dose remained significantly associated with major depressive disorder and being hospitalized. Doses of ADs have increased somewhat in Asia and were higher when used for major depression or anxiety disorders than for bipolar depression and for hospitalized psychiatric patients.

Adoption and correlates of Postgraduate Hospital Educational Environment Measure (PHEEM) in the evaluation of learning environments - A systematic review.

BACKGROUND: The Postgraduate Hospital Educational Environment Measure (PHEEM) is a highly reliable and valid instrument to measure the educational environment during post graduate medical training. This review extends earlier reports by evaluating the extant adoption of PHEEM in various international clinical training sites, and its significant correlations in order to expand our understanding on the use of PHEEM and facilitate future applications and research. METHOD: A systematic literature review was conducted on all articles between 2005 and October 2015 that adopted and reported data using the PHEEM. RESULTS: Overall 30 studies were included, encompassing data from 14 countries internationally. Notable differences in the PHEEM scores were found between different levels of training, disciplines, and clinical training sites. Common strengths and weaknesses in learning environments were observed and there were significant correlations between PHEEM scores and In-Training Exam (ITE) performance (positive correlation) and level of burnout (negative correlation), respectively. CONCLUSIONS: PHEEM is widely adopted in different learning settings, and is a useful tool to identify the strengths and weaknesses of an educational environment. Future research can examine other correlates of PHEEM and longitudinal changes in interventional studies.
