Depression and suicidal ideation among Black individuals in Canada: mediating role of traumatic life events and moderating role of racial microaggressions and internalized racism.

PURPOSE: Although suicidal ideation (SI) is a serious concern in Canada, its prevalence and related factors among Black individuals are poorly documented. Using data from the Mental Health of Black Communities in Canada project (BeCoMHeal), this study aimed to assess the prevalence of SI in Black individuals aged 15-40 years old in Canada, the mediating role of traumatic life events in the association between depression and SI, and the moderating role of racial microaggressions and internalized racism. METHODS: Eight hundred and sixty participants aged between 15 and 40 years (Mage =24.96, SD = 6.29) completed the online questionnaire assessing sociodemographic data, depression symptoms, traumatic life events, racial microaggressions, internalized racism, and SI. RESULTS: Findings showed that 25.7% of the participants reported having experienced SI (26.5% women, 22.7% men, 𝛘2 = 1.08, p = .299). The moderated-mediation model revealed that traumatic life events fully mediated the association between depression and SI (B = 0.12, p = .004; 95% CI, [0.04, 0.20]) and that racial microaggressions (B = - 0.03, p = .042; 95% CI [-0.07, - 0.00]) and internalized racism (B = 0.06, p = .006; 95% CI [0.02, 0.10]) moderated this relationship. CONCLUSION: These findings underscore the importance of addressing racial microaggressions and internalized racism in therapy contexts among Black individuals to mitigate the potential negative impacts on their mental health. They also emphasize the need to develop effective, culturally sensitive, and racially adapted suicide prevention and intervention programs for Black communities in Canada.

Longitudinal Impact of the COVID-19 Pandemic on Stress and Occupational Well-Being of Mental Health Professionals: An International Study.

BACKGROUND: Increased levels of occupational stress among health professionals during the COVID-19 pandemic have been documented. Few studies have examined the effects of the pandemic on mental health professionals despite the heightened demand for their services. METHOD: A multilingual, longitudinal, global survey was conducted at 3 time points during the pandemic among members of the World Health Organization's Global Clinical Practice Network. A total of 786 Global Clinical Practice Network members from 86 countries responded to surveys assessing occupational distress, well-being, and posttraumatic stress symptoms. RESULTS: On average, respondents' well-being deteriorated across time while their posttraumatic stress symptoms showed a modest improvement. Linear growth models indicated that being female, being younger, providing face-to-face health services to patients with COVID-19, having been a target of COVID-related violence, and living in a low- or middle-income country or a country with a higher COVID-19 death rate conveyed greater risk for poor well-being and higher level of stress symptoms over time. Growth mixed modeling identified trajectories of occupational well-being and stress symptoms. Most mental health professions demonstrated no impact to well-being; maintained moderate, nonclinical levels of stress symptoms; or showed improvements after an initial period of difficulty. However, some participant groups exhibited deteriorating well-being approaching the clinical threshold (25.8%) and persistently high and clinically significant levels of posttraumatic stress symptoms (19.6%) over time. CONCLUSIONS: This study indicates that although most mental health professionals exhibited stable, positive well-being and low stress symptoms during the pandemic, a substantial minority of an already burdened global mental health workforce experienced persistently poor or deteriorating psychological status over the course of the pandemic.

Incidence, Racial Disparities and Factors Related to Psychosis among Black Individuals in Canada: A Scoping Review.

OBJECTIVE: Black communities are increasingly concerned about psychosis, a worry echoed by provincial health-care systems across Canada. Responding to the lack of evidence on psychosis in Black communities, this scoping review examined the incidence and prevalence of psychosis, access to care (pathways to care, coercive referrals, interventions, etc.), treatments received, and stigma faced by individuals with psychosis. METHOD: To identify studies, a comprehensive search strategy was developed and executed in December 2021 across 10 databases, including APA PsycInfo, CINAHL, MEDLINE and Web of Science. Subject headings and keywords relating to Black communities, psychosis, health inequalities, Canada and its provinces and territories were used and combined. The scoping review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping review (PRISMA-ScR) reporting standard. RESULTS: A total of 15 studies met the inclusion criteria, all of them conducted in Ontario and Quebec. Results highlight different disparities in psychosis among Black communities. Compared to other Canadian ethnic groups, Black individuals are more likely to be diagnosed with psychosis. Black individuals with psychosis are more likely to have their first contact with health-care settings through emergency departments, to be referred by police and ambulance services, and to experience coercive referrals and interventions, and involuntary admission. Black individuals experience a lower quality of care and are the ethnic group most likely to disengage from treatment. CONCLUSION: This scoping review reveals many gaps in research, prevention, promotion and intervention on psychosis in Black individuals in Canada. Future studies should explore factors related to age, gender, social and economic factors, interpersonal, institutional and systemic racism, and psychosis-related stigma. Efforts should be directed toward developing trainings for health-care professionals and promotion and prevention programs within Black communities. Culturally adapted interventions, racially disaggregated data, and increased research funding are needed.

Case-controlled field study of the ICD-11 clinical descriptions and diagnostic requirements for Bodily Distress Disorders.

AIMS: Mental disorders characterized by preoccupation with distressing bodily symptoms and associated functional impairment have been a target of major reconceptualization in the ICD-11, in which a single category of Bodily Distress Disorder (BDD) with different levels of severity replaces most of the Somatoform Disorders in ICD-10. This study compared the accuracy of clinicians' diagnosis of disorders of somatic symptoms using either the ICD-11 or ICD-10 diagnostic guidelines in an online study. METHODS: Clinically active members of the World Health Organization's Global Clinical Practice Network (N = 1065) participating in English, Spanish, or Japanese were randomly assigned to apply ICD-11 or ICD-10 diagnostic guidelines to one of nine pairs of standardized case vignettes. The accuracy of the clinicians' diagnoses as well as their ratings of the guidelines' clinical utility were assessed. RESULTS: Overall, clinicians were more accurate using ICD-11 compared to ICD-10 for every presentation of a vignette characterized primarily by bodily symptoms associated with distress and impairment. Clinicians who made a diagnosis of BDD using ICD-11 were generally correct in applying the severity specifiers for the condition. LIMITATIONS: This sample may represent some self-selection bias and thus may not generalize to all clinicians. Additionally, diagnostic decisions with live patients may lead to different results. CONCLUSIONS: The ICD-11 diagnostic guidelines for BDD represent an improvement over those for Somatoform Disorders in ICD-10 in regard to clinicians' diagnostic accuracy and perceived clinical utility.

Frequency and factors related to substance use among Black individuals aged 15-40 years old in Canada: The role of everyday racial discrimination.

OBJECTIVE: Despite evidence that Black individuals are confronted with various types of racial discrimination that put them at risk for alcohol and substance use disorders, no study in Canada has assessed the frequency and factors related to substance use in Black communities. This study thus aims to examine the frequency and factors related to substance use in Black communities in Canada. METHOD: A total of 845 Black individuals in Canada (76.6% female) completed questionnaires assessing substance use (i.e., alcohol, cannabis, and other drugs), everyday racial discrimination, resilience, religious involvement, and sociodemographic information. Multivariable regression analyses were used to determine factors related to substance use among Black individuals. RESULTS: The findings showed that 14.8% (95% CI [8.60, 20.94]) of participants reported using any substance (i.e., alcohol, cannabis, and other drugs) in the past 12 months. Men reported a significantly higher frequency of substance use than women (25.7% vs. 11.1%; x² = 27.67, p < .001). Everyday racial discrimination (ß = .27, p < .001) and place of birth (born in Canada, ß = .14, p < .001) were positively associated with substance use, whereas it was negatively associated with religiosity, resilience, and gender (being a female; ß = -.08, p < .05; ß = -.21, p < .001; ß = -.12, p < .001). CONCLUSIONS: Racial discrimination is associated with substance use among Black individuals in Canada. The study findings inform potential prevention and intervention strategies by examining protective factors related to substance use (e.g., religiosity, resilience, gender) among Black individuals.

Prevalence and risk factors associated with psychostimulant use among Black individuals: A meta-analysis and systematic review.

BACKGROUND: Psychostimulants (e.g., cocaine, amphetamine) are among the most widely used drugs globally with detrimental short and long-term physical, psychological and social consequences. There is limited data on psychostimulant use for various racial and ethnic groups, including Black people, and the challenges they face living as minorities overcoming historical challenges including increased incarceration associated with drug possession. METHODS: Peer-reviewed articles were identified in five databases (APA PsycInfo, CINAHL, Cochrane CENTRAL, Embase, MEDLINE). Eligible studies were published in French or English, provided empiral data on psychostimulant use in Black individuals living in a minority context. The PRISMA guideline was used for structuring the review. Random-effects meta-analyses were generated to estimate the pooled prevalence of lifetime and periodic psychostimulant use among Black individuals using STATA 16. RESULTS: Sixty-three studies published from 1991 to 2022 with a sample size of 139,683 Black individuals were included in the current meta-analysis. Results indicate a pooled prevalence estimate of 11.4% for any form of psychostimulant use among Black individuals. The pooled prevalence estimates were 12.4% (95% CI, 8.4% - 16.4%) for cocaine, 8.3% (95% CI, 0% - 19.1%) for amphetamines, and 11.4% (95% CI, 4.6% - 18.1%) for other stimulants. Prediction intervals for all psychostimulant types were highly heterogenous ranging from 0% to as high as 51.2% for amphetamine suggesting prevalence of use in some studies of Black people could be found to be as low as zero. Subgroup analyses were conducted to examine differences between age groups, gender, reference period, and type of assessment. CONCLUSIONS: High prevalence rates of psychostimulant use among Black people argues for greater access to evidence-based treatments. However, current psychosocial interventions are suboptimal, warranting further study. Consideration needs to be given to the challenges of the large range of prediction intervals, living in urban areas, racial discrimination experiences, race-based stress, and sociodemographic characteristics, including poverty, education level, age, gender.

Prevalence of Current PTSD Symptoms Among a Sample of Black Individuals Aged 15 to 40 in Canada: The Major Role of Everyday Racial Discrimination, Racial Microaggresions, and Internalized Racism.

OBJECTIVE: Most Black individuals in Canada report having experienced racial discrimination. Although previous studies have shown that there is a strong relationship between racial discrimination and posttraumatic stress disorder (PTSD), no studies in Canada have documented this association among Black individuals. The present study documents (1) the prevalence of PTSD among Black individuals using data from the Black Communities Mental Health project and (2) risk factors associated with PTSD, including racial microaggressions, everyday racial discrimination, and internalized racism. METHOD: A total of 860 participants (75.6% of women) aged 15 to 40 years old (M = 24.96, SD = 6.29) completed questionnaires assessing PTSD, experience of traumatic events, racial microaggressions, everyday racial discrimination, and internalized racism. RESULTS: Findings showed that 95.1% of participants reported exposure to at least one traumatic event during their lifetime. In total, 67.11% of participants reported probable PTSD with no significant difference between men and women (68.2% and 67.8%, χ2 = 0.132, p = 0.72). Participants born in Canada were more likely to experience significant PTSD symptoms, compared to those born abroad (70.92% and 53.14%, χ2 = 19.69, p < 0.001). A multivariable linear regression model of PTSD symptoms was computed using sociodemographic variables and exposure to traumatic events as independent variables, which explained 25.9% of the variance. In addition to these variables, a second model included racial microaggressions, everyday racial microaggressions, and internalized racism, which explained 51.8% of the variance. The model showed that traumatic events (b = 0.6; p = 0.02), racial microaggressions (b = 0.5; p < 0.001), everyday discrimination (b = 0.2; p = 0.03) and internalized racism (b = 0.5; p < 0.001) were positively associated with PTSD symptoms. CONCLUSIONS: This article highlights the detrimental consequences of racial discrimination against Black people in Canada. Prevention and mental health programs aimed at mitigating its consequences on the lives of Black people and other racialized populations must be implemented.

Perceived racial discrimination, psychosomatic symptoms, and resilience among Black individuals in Canada: A moderated mediation model.

OBJECTIVE: Although no study has explored psychosomatic symptoms in Black communities in Canada, several studies in the United States showed that psychological distress is often express as physical pain among African Americans. Using a cross-sectional design, the present study documents the frequency of psychosomatic symptoms and its association to racial discrimination, and resilience among Black individuals aged 15 to 40 in Canada. METHOD: A total of 860 participants (Mage = 25.0 years, SD = 6.3), predominantly born in Canada (79.1%) and women (75.6%), completed the Symptom Checklist-90-Revised (somatization subscale), the Everyday Discrimination Scale, and the Resilience Scale-14. RESULTS: Findings revealed that 81.7% of participants experienced psychosomatic symptoms, with higher prevalence among women (84.2%) compared to men (70.7%;), ꭓ2 = 21.5, p < .001; participants aged 25 to 40 years old (93.7%) compared to those aged 15-24 years old (75.2%) (ꭓ2 = 45.0, p < .001). Participants reporting greater racial discrimination had more psychosomatic symptoms (89.4%) compared to others (72.9%), ꭓ2 = 39.2, p < .001). A moderated mediation model showed that everyday racial discrimination was positively associated with psychosomatic symptoms (B = 0.1, SE = 0.01, p < .001). The model showed that the association between racial discrimination and psychosomatic symptoms was partially mediated by resilience (B = -0.01, SE = 0.0, p < .01), and negatively moderated by gender (B = -0.04, SE = 0.01, p < .01). In other words, being a woman is associated with higher levels of psychosomatic symptoms among those who have experienced racial discrimination. CONCLUSION: By highlighting the association between racial discrimination and psychosomatic symptoms and the role of resilience and gender in this relation, this article reveals important factors to integrate to improve healthcare services, prevention, and interventions among Black individuals with psychosomatic symptoms.

Prevalence and correlates of anxiety symptoms among Black people in Canada: A significant role for everyday racial discrimination and racial microaggressions.

OBJECTIVE: Anxiety disorders are highly prevalent worldwide but vary significantly by country and ethnoracial background. Minimal published data exist on the prevalence of clinically significant anxiety among Black people in Canada and none using validated measures. Therefore, this study sought to establish the frequency of clinically significant anxiety symptoms among a sample of Black people living in Canada as well as examine the association with two forms of racism (racial discrimination and racial microaggressions). METHODS: Data collected from the Black Community Mental Health project in Canada was analyzed. Participants provided (N= 845) sociodemographic information and completed measures assessing anxiety symptomology (GAD-7), everyday racial discrimination, racial microaggressions, and resilience. Prevalence of anxiety symptomatology was determined across sociodemographic variables as well as categories of everyday racial discrimination and racial microaggressions. Two regression models were conducted to examine the relationship between anxiety symptoms and the two forms of racism controlling for sociodemographic factors. RESULTS: Overall, nearly a third of participants endorsed clinically significant levels of anxiety symptoms, with higher rates observed among men, unemployed people, those with higher education, people who are separated, and those with no reported family history of mental health problems. Logistic regression models demonstrated that, except for those reporting the greatest frequency of racial discrimination, there is a general linear trend such that those experiencing higher levels of racial discrimination or racial microaggressions are increasingly more likely to present with anxiety symptoms when compared to those reporting low levels of discrimination or microaggressions. Psychological resilience afforded nominal protection but only against exposure to racial microaggressions. CONCLUSIONS: Rates of clinically significant anxiety are higher among Black people in Canada than reported previously. Both racial discrimination and racial microaggressions predicted higher rates of anxiety symptoms. The results are discussed in relation to previous findings from the US that report similar findings.

Prevalence of ADHD among Black Youth Compared to White, Latino and Asian Youth: A Meta-Analysis.

OBJECTIVE: To systematically review the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) among Black children and adolescents compared to White, Latino and Asian children and adolescents. METHOD: Peer-reviewed articles were identified in seven databases and included if they reported prevalence of ADHD among Black children and adolescents living in a minority context and compared rates to at least one of White, Latino or Asian samples. A total of 7050 articles were retrieved and 155 articles were subjected to full evaluation. Twenty-three studies representing 26 independent samples were included. RESULTS: The pooled sample size was n = 218,445 (k = 26), n = 835,505 (k = 25), n = 493,417 (k = 24), and n = 66,413 (k = 7) of Black, White, Latino, and Asian participants, respectively. Pooled prevalence rate of ADHD was 15.9% (95%CI 11.6% - 20.7%) among Black children and adolescents, 16.6% (95%CI 11.6% - 22.2%) among Whites, 10.1% (95%CI 6.9% - 13.8%) among Latinos and 12.4% (95%CI 1.4% - 31.8%) among Asians. There was no significant difference in prevalence between ethnic groups, whereas both Black and White children and adolescents had marginally statistically significant higher prevalence than Asians. The results of a meta-regression analysis showed no moderating effects of the type of sample and the year of publication of studies. A significant publication bias was observed, suggesting that other moderators were not identified in the present systematic review. CONCLUSION: In contrast to the assertion in the DSM-5 that clinical identification among Black children and adolescents is lower than among White children and adolescents, the present meta-analysis suggests similar rates of ADHD among these two groups. The importance of considering cultural appropriateness of assessment tools and processes is emphasized.

Perceived racial discrimination, internalized racism, social support, and self-esteem among Black individuals in Canada: A moderated mediation model.

OBJECTIVES: Black Canadians report experiencing various forms of racial discrimination disproportionately. This study aimed to: (a) examine the association between everyday racial discrimination and self-esteem; (b) test the mediating role of internalized racism and social support in the association between racial discrimination and self-esteem, and (c) test the moderating role of gender and age in this same relationship. METHOD: A total of 860 participants (76.60% female) aged 15-40 (Mage = 24.96, SD = 6.31) completed questionnaires assessing racial discrimination, self-esteem, internalized racism, and social support. Descriptive and moderated mediation analyses were performed. RESULTS: A total of 65.33% of participants were categorized as endorsing low self-esteem, with no significant difference between males and females (66.67% and 62.20%, respectively; χ² = 1.56, p = .47). Participants aged 25-40 exhibited a higher prevalence of low self-esteem compared to those aged 15-24 (89.91% and 58.54%, respectively, χ² = 37.31, p < .001). The results showed a progressive increase in the prevalence of low self-esteem commensurate with increasing levels of reported racial discrimination. Internalized racism (ß = -.09, SE = .01, p < .001) and social support (ß = .10, SE = .01, p < .001) mediated the association between everyday racial discrimination and self-esteem; whereas gender moderated the latter association (ß = .17, SE = .04, p < .001; being a woman). CONCLUSIONS: Results indicate a strong association between racial discrimination and low self-esteem. These findings provide a better understanding of the mechanisms underlying the development of self-esteem problems among Black individuals in Canada. They also have important relevance for the development of educational and clinical programs for prevention and intervention. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

An international survey examining the impact of the COVID-19 pandemic on telehealth use among mental health professionals.

BACKGROUND: COVID-19 has profoundly affected the work of mental health professionals with many transitioning to telehealth to comply with public health measures. This large international study examined the impact of the pandemic on mental health clinicians' telehealth use. METHODS: This survey study was conducted with mental health professionals, primarily psychiatrists and psychologists, registered with WHO's Global Clinical Practice Network (GCPN). 1206 clinicians from 100 countries completed the telehealth section of the online survey in one of six languages between June 4 and July 7, 2020. Participants were asked about their use, training (i.e., aspects of telehealth addressed), perceptions, and concerns. OUTCOMES: Since the pandemic onset, 1092 (90.5%) clinicians reported to have started or increased their telehealth services. Telephone and videoconferencing were the most common modalities. 592 (49.1%) participants indicated that they had not received any training. Clinicians with no training or training that only addressed a single aspect of telehealth practice were more likely to perceive their services as somewhat ineffective than those with training that addressed two or more aspects. Most clinicians indicated positive perceptions of effectiveness and patient satisfaction. Quality of care compared to in-person services and technical issues were the most common concerns. Findings varied by WHO region, country income level, and profession. INTERPRETATION: Findings suggest a global practice change with providers perceiving telehealth as a viable option for mental health care. Increasing local training opportunities and efforts to address clinical and technological concerns is important for meeting ongoing demands.

Exploring Mental Health Professionals' Experiences of Intimate Partner Violence-Related Training: Results From a Global Survey.

Intimate partner violence (IPV) is a global public health problem that has been shown to lead to serious mental health consequences. Due to its frequent co-occurrence with psychiatric disorders, it is important to assess for IPV in mental health settings to improve treatment planning and referral. However, lack of training in how to identify and respond to IPV has been identified as a barrier for the assessment of IPV. The present study seeks to better understand this IPV-related training gap by assessing global mental health professionals' experiences of IPV-related training and factors that contribute to their likelihood of receiving training. Participants were French-, Spanish-, and Japanese-speaking psychologists and psychiatrists (N = 321) from 24 nations differing on variables related to IPV, including IPV prevalence, IPV-related norms, and IPV-related laws. Participants responded to an online survey asking them to describe their experiences of IPV-related training (i.e., components and hours of training) and were asked to rate the frequency with which they encountered IPV in clinical practice and their level of knowledge and experience related to relationship problems; 53.1% of participants indicated that they had received IPV-related training. Clinicians from countries with relatively better implemented laws addressing IPV and those who encountered IPV more often in their regular practice were more likely to have received training. Participants who had received IPV-related training, relative to those without training, were more likely to report greater knowledge and experience related to relationship problems. Findings suggest that clinicians' awareness of IPV and the institutional context in which they practice are related to training. Training, in turn, is associated with subjective appraisals of knowledge and experience related to relationship problems. Increasing institutional efforts to address IPV (e.g., implementing IPV legislation) may contribute to improved practices with regard to IPV in mental health settings.

Evaluating the Relationship Between Intimate Partner Violence-Related Training and Mental Health Professionals' Assessment of Relationship Problems.

Intimate partner violence (IPV) is a serious public health problem associated with increased risk of developing mental health conditions. Assessment of IPV in mental health settings is important for appropriate treatment planning and referral; however, lack of training in how to identify and respond to IPV presents a significant barrier to assessment. To address this issue, the World Health Organization (WHO) advanced a series of evidence-based recommendations for IPV-related training programs. This study examines the relationship between mental health professionals' experiences of IPV-related training, including the degree to which their training resembles WHO training recommendations, and their accuracy in correctly identifying relationship problems. Participants were psychologists and psychiatrists (N = 321) from 24 countries who agreed to participate in an online survey in French, Japanese, or Spanish. They responded to questions regarding their IPV-related training (i.e., components and hours of training) and rated the presence or absence of clinically significant relationship problems and maltreatment (RPM) and mental disorders across four case vignettes. Participants who received IPV-related training, and whose training was more recent and more closely resembled WHO training recommendations, were more likely than those without training to accurately identify RPM when it was present. Clinicians regardless of IPV-related training were equally likely to misclassify normative couple issues as clinically significant RPM. Findings suggest that IPV-related training assists clinicians in making more accurate assessments of patients presenting with clinically significant relationship problems, including IPV. These data inform recommendations for IPV-related training programs and suggest that training should be repeated, multicomponent, and include experiential training exercises, and guidelines for distinguishing normative relationship problems from clinically significant RPM.

A global field study of the international classification of diseases (ICD-11) mood disorders clinical descriptions and diagnostic guidelines.

BACKGROUND: We report results of an internet-based field study evaluating the diagnostic guidelines for ICD-11 mood disorders. Accuracy of clinicians' diagnostic judgments applying draft ICD-11 as compared to the ICD-10 guidelines to standardized case vignettes was assessed as well as perceived clinical utility. METHODS: 1357 clinician members of the World Health Organization's Global Clinical Practice Network completed the study in English, Spanish, Japanese or Russian. Participants were randomly assigned to apply ICD-11 or ICD-10 guidelines to one of eleven pairs of case vignettes. RESULTS: Clinicians using the ICD-11 and ICD-10 guidelines achieved similar levels of accuracy in diagnosing mood disorders depicted in vignettes. Those using the ICD-11 were more accurate in identifying depressive episode in recurrent depressive disorder. There were no statistically significant differences detected across classifications in the accuracy of identifying dysthymic or cyclothymic disorder. Circumscribed problems with the proposed ICD-11 guidelines were identified including difficulties differentiating bipolar type I from bipolar type II disorder and applying revised severity ratings to depressive episodes. Clinical utility of ICD-11 bipolar disorders was found to be significantly lower than for ICD-10 equivalent categories. LIMITATIONS: Standardized case vignettes were manipulated to evaluate specific changes. The degree of accuracy of clinicians' diagnostic judgments may not reflect clinical decision-making with patients. CONCLUSIONS: Alignment of the ICD-11 with current research appears to have been achieved without sacrificing diagnostic accuracy or clinical utility though specific training may be necessary as ICD-11 is implemented worldwide. Areas in which the ICD-11 guidelines did not perform as intended resulted in further revisions.

An organization- and category-level comparison of diagnostic requirements for mental disorders in ICD-11 and DSM-5.

In 2013, the American Psychiatric Association (APA) published the 5th edition of its Diagnostic and Statistical Manual of Mental Disorders (DSM-5). In 2019, the World Health Assembly approved the 11th revision of the International Classification of Diseases (ICD-11). It has often been suggested that the field would benefit from a single, unified classification of mental disorders, although the priorities and constituencies of the two sponsoring organizations are quite different. During the development of the ICD-11 and DSM-5, the World Health Organization (WHO) and the APA made efforts toward harmonizing the two systems, including the appointment of an ICD-DSM Harmonization Group. This paper evaluates the success of these harmonization efforts and provides a guide for practitioners, researchers and policy makers describing the differences between the two systems at both the organizational and the disorder level. The organization of the two classifications of mental disorders is substantially similar. There are nineteen ICD-11 disorder categories that do not appear in DSM-5, and seven DSM-5 disorder categories that do not appear in the ICD-11. We compared the Essential Features section of the ICD-11 Clinical Descriptions and Diagnostic Guidelines (CDDG) with the DSM-5 criteria sets for 103 diagnostic entities that appear in both systems. We rated 20 disorders (19.4%) as having major differences, 42 disorders (40.8%) as having minor definitional differences, 10 disorders (9.7%) as having minor differences due to greater degree of specification in DSM-5, and 31 disorders (30.1%) as essentially identical. Detailed descriptions of the major differences and some of the most important minor differences, with their rationale and related evidence, are provided. The ICD and DSM are now closer than at any time since the ICD-8 and DSM-II. Differences are largely based on the differing priorities and uses of the two diagnostic systems and on differing interpretations of the evidence. Substantively divergent approaches allow for empirical comparisons of validity and utility and can contribute to advances in the field.

Accuracy of diagnostic judgments using ICD-11 vs. ICD-10 diagnostic guidelines for obsessive-compulsive and related disorders.

BACKGROUND: We report results of an internet-based field study evaluating the diagnostic guidelines for the newly introduced ICD-11 grouping of obsessive-compulsive and related disorders (OCRD). We examined accuracy of clinicians' diagnostic judgments applying draft ICD-11 as compared to the ICD-10 diagnostic guidelines to standardized case vignettes. METHODS: 1,717 mental health professionals who are members of the World Health Organization's Global Clinical Practice Network completed the study in Chinese, English, French, Japanese, Russian or Spanish. Participants were randomly assigned to apply ICD-11 or ICD-10 guidelines to one of nine pairs of case vignettes. RESULTS: Participants using ICD-11 outperformed those using ICD-10 in correctly identifying newly introduced OCRD, although results were mixed for differentiating OCRD from disorders in other groupings largely due to clinicians having difficulty differentiating challenging presentations of OCD. Clinicians had difficulty applying a three-level insight qualifier, although the 'poor to absent' level assisted with differentiating OCRD from psychotic disorders. Brief training on the rationale for an OCRD grouping did not improve diagnostic accuracy suggesting sufficient detail of the proposed guidelines. LIMITATIONS: Standardized case vignettes were manipulated to include specific characteristics; the degree of accuracy of clinicians' diagnostic judgments about these vignettes may not generalize to application in routine clinical practice. CONCLUSIONS: Overall, use of the ICD-11 guidelines resulted in more accurate diagnosis of case vignettes compared to the ICD-10 guidelines, particularly in differentiating OCRD presentations from one another. Specific areas in which the ICD-11 guidelines did not perform as intended provided the basis for further revisions to the guidelines.

The classification of feeding and eating disorders in the ICD-11: results of a field study comparing proposed ICD-11 guidelines with existing ICD-10 guidelines.

BACKGROUND: The World Health Organization (WHO) International Classification of Diseases and Related Health Problems (ICD) is used globally by 194 WHO member nations. It is used for assigning clinical diagnoses, providing the framework for reporting public health data, and to inform the organization and reimbursement of health services. Guided by overarching principles of increasing clinical utility and global applicability, the 11th revision of the ICD proposes major changes that incorporate empirical advances since the previous revision in 1992. To test recommended changes in the Mental, Behavioral, and Neurodevelopmental Disorders chapter, multiple vignette-based case-controlled field studies have been conducted which examine clinicians' ability to accurately and consistently use the new guidelines and assess their overall clinical utility. This manuscript reports on the results from the study of the proposed ICD-11 guidelines for feeding and eating disorders (FEDs). METHOD: Participants were 2288 mental health professionals registered with WHO's Global Clinical Practice Network. The study was conducted in Chinese, English, French, Japanese, and Spanish. Clinicians were randomly assigned to apply either the ICD-11 or ICD-10 diagnostic guidelines for FEDs to a pair of case vignettes designed to test specific clinical questions. Clinicians selected the diagnosis they thought was correct for each vignette, evaluated the presence of each essential feature of the selected diagnosis, and the clinical utility of the diagnostic guidelines. RESULTS: The proposed ICD-11 diagnostic guidelines significantly improved accuracy for all FEDs tested relative to ICD-10 and attained higher clinical utility ratings; similar results were obtained across all five languages. The inclusion of binge eating disorder and avoidant-restrictive food intake disorder reduced the use of residual diagnoses. Areas needing further refinement were identified. CONCLUSIONS: The proposed ICD-11 diagnostic guidelines consistently outperformed ICD-10 in distinguishing cases of eating disorders and showed global applicability and appropriate clinical utility. These results suggest that the proposed ICD-11 guidelines for FEDs will help increase accuracy of public health data, improve clinical diagnosis, and enhance health service organization and provision. This is the first time in the revision of the ICD that data from large-scale, empirical research examining proposed guidelines is completed in time to inform the final diagnostic guidelines.

The reliability and clinical utility of ICD-11 schizoaffective disorder: A field trial.

A major goal for the revision of the International Classification of Diseases and Related Health Problems, Tenth Edition (ICD-10) is to increase the clinical utility of the diagnostic system. Schizoaffective disorder has a history of poor diagnostic reliability due to the similarities and overlap in symptoms that it shares with other disorders, especially primary psychotic and mood disorders. The present study was part of the case-controlled field trials for ICD-11 and examines how the proposed changes for schizoaffective disorder may improve differential diagnosis and diagnostic accuracy. Clinicians from around the globe (n = 873) were provided with either ICD-10 or ICD-11 diagnostic guidelines and asked to apply them to case vignettes comparing schizoaffective disorder to schizophrenia and mood disorders with psychotic symptoms. Participants were asked to respond to follow-up diagnostic questions to determine which components of the diagnostic guidelines affected diagnostic accuracy. Overall, clinicians showed small improvements in accurately diagnosing vignettes using ICD-11 over ICD-10. Results suggest the discrepancy in diagnosing schizoaffective disorder is related primarily to the presence of mood symptoms and discrepancies about whether those symptoms are more consistent with schizoaffective disorder or a mood disorder diagnosis. Continuing to identify ways to more accurately capture this symptom picture will be important in the future as well as systematic efforts to educate clinicians about differential diagnosis.
