Applying the Somatic Symptom Disorder Diagnosis to Individuals with Fibromyalgia: Strengths and Limitations.

Amidst broad changes to the somatic disorder diagnoses, DSM-IV pain disorder was absorbed into DSM-5's somatic symptom disorder (SSD) as a specifier. However, clinical research testing of its use for the chronic pain population has been limited and its utility remains inconclusive. Using the exemplar of fibromyalgia, this article evaluates the validity, reliability, clinical utility, and acceptability of the SSD pain specifier. The diagnosis appears to have moderate validity but low specificity for the fibromyalgia population. The pain specifier has neither undergone sufficient field testing nor been evaluated for use by medical providers, with available data suggesting low reliability. Further research is needed to establish clinical utility via assessment of differential treatment outcomes. Concerns about social, legal, and economic consequences of classifying pain patients with a mental health diagnosis are outstanding. The current SSD criteria should be used with caution among the fibromyalgia patient population until its application for chronic pain has been further researched.

Mental health professionals' use of the ICD-11 classification of impulse control disorders and behavioral addictions: An international field study.

Background and aims: The ICD-11 chapter on mental, behavioral and neurodevelopmental disorders contains new controversial diagnoses including compulsive sexual behavior disorder (CSBD), intermittent explosive disorder (IED) and gaming disorder. Using a vignette-based methodology, this field study examined the ability of mental health professionals (MHPs) to apply the new ICD-11 diagnostic requirements for impulse control disorders, which include CSBD and IED, and disorders due to addictive behaviors, which include gaming disorder, compared to the previous ICD-10 guidelines. Methods: Across eleven comparisons, members of the WHO's Global Clinical Practice Network (N = 1,090) evaluated standardized case descriptions that were designed to test key differences between the diagnostic guidelines of ICD-11 and ICD-10. Results: The ICD-11 outperformed the ICD-10 in the accuracy of diagnosing impulse control disorders and behavioral addictions in most comparisons, while the ICD-10 was not superior in any. The superiority of the ICD-11 was particularly clear where new diagnoses had been added to the classification system or major revisions had been made. However, the ICD-11 outperformed the ICD-10 only in a minority of comparisons in which mental health professionals were asked to evaluate cases with non-pathological high involvement in rewarding behaviors. Discussion and Conclusions: Overall, the present study indicates that the ICD-11 diagnostic requirements represent an improvement over the ICD-10 guidelines. However, additional efforts, such as training programs for MHPs and possible refinements of diagnostic guidance, are needed to avoid over-diagnosis of people who are highly engaged in a repetitive and rewarding behavior but below the threshold for a disorder.

Examining accurate diagnosis of complex PTSD in ICD-11.

BACKGROUND: Complex posttraumatic stress disorder (complex PTSD), the most frequently suggested new category for inclusion by mental health professionals, has been included in the Eleventh Revision of the World Health Organization's International Classification of Diseases (ICD-11). Research has yet to explore whether clinicians' recognition of the distinct complex PTSD symptoms predicts giving the correct diagnosis. The present study sought to determine if international mental health professionals were able to accurately diagnose complex PTSD and identify the shared PTSD features and three essential diagnostic features, specific to complex PTSD. METHODS: Participants were randomly assigned to view two vignettes and tasked with providing a diagnosis (or indicating that no diagnosis was warranted). Participants then answered a series of questions regarding the presence or absence of each of the essential diagnostic features specific to the diagnosis they provided. RESULTS: Clinicians who recognized the presence or absence of complex PTSD specific features were more likely to arrive at the correct diagnostic conclusion. Complex PTSD specific features were significant predictors while the shared PTSD features were not, indicating that attending to each of the specific symptoms was necessary for diagnostic accuracy of complex PTSD. LIMITATIONS: The use of written case vignettes including only adult patients and a non-representative sample of mental health professionals may limit the generalizability of the results. CONCLUSIONS: Findings support mental health professionals' ability to accurately identify specific features of complex PTSD. Future work should assess whether mental health providers can effectively identify symptoms of complex PTSD in a clinical setting.

Measurement invariance of the Personality Inventory for the DSM-5 (PID-5) for Nigerian and White American university students.

In a previous study, it was reported that the typically replicable factor structure of the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders, fifth edition (PID-5) was noninvariant across samples of Black American and White American university students. The investigators of that study attributed this noninvariance across these two racial groups to Black American racialization, defined as Black individuals living in a predominantly non-Black society. In the current investigation, we examined further the effects of Black racialization by examining PID-5 factor structure invariance using a sample of nonracialized Black (Nigerian) university students (i.e., Black people living in a primarily Black society) and a sample of White American students. The factor structure of the PID-5 across the samples indicated overall configural invariance, suggesting that the same PID-5 facet traits, for the most part, load on the same factors for the nonracialized Black people and White Americans. This result is consistent with the view that Black racialization likely contributes to PID-5 factor structure noninvariance across White and Black Americans. There were some differences, however, between the Nigerian and White American students with respect to metric invariance and scalar invariance, suggesting the facet-to-factor loadings have different magnitudes of association across groups and that domain scale score elevations in Nigerian and White American students are not comparable; this was particularly prominent for the disinhibition domain.

Utility of the Teacher Behavior Checklist beyond Psychology Majors: Replication with Brazilian Physical Education Students / Utilidad del Teacher Behavior Checklist más allá de la psicología: replicación con estudiantes brasileños de educación física

Abstract The Teacher Behavior Checklist (TBC) is a worldwide valued instrument to measure teachers' performance. Nonetheless, the studies about TBC in Brazil are still scarce, with samples mainly composed of psychology and civil engineering students. The aim of this study was to replicate the research by Keeley et al. (2010) to evaluate the psychometric properties of the Brazilian version of the TBC with a new sample. Participants were 107 undergraduates from physical education courses from a Brazilian public university. Participants used the TBC to evaluate three types of teachers: the worst they had ever had, a regular one, and the best one. The order of evaluation of teacher types did not interfere with the response patterns, but as expected, statistically significant differences were found among the three types of teachers. Additionally, the two-factor model of the TBC was confirmed through Confirmatory Factor Analysis, providing additional evidence of construct validity. However evidence to advocate in favor of a one-factor solution was also found. McDonald's Omega results provided evidence of reliability. These findings support the use of TBC in the formative evaluation of teachers in Brazil.

Resumen The Teacher Behavior Checklist (TBC) es un instrumento valorado en todo el mundo para medir el desempeño de los profesores. Sin embargo, los estudios sobre el TBC en Brasil siguen siendo escasos, con muestras compuestas principalmente por estudiantes de psicología e ingeniería civil. El objetivo de este estudio fue replicar la investigación de Keeley et al. (2010) para evaluar las propiedades psicométricas de la versión brasileña del Teacher Behavior Checklist (TBC) con una nueva muestra. Participaron 107 estudiantes de educación física de una universidad pública brasileña. Los participantes utilizaron el TBC para evaluar tres tipos de profesores: el peor que hayan tenido, uno regular y el mejor. El orden de evaluación de los tipos de docentes no interfirió con los patrones de respuesta, pero como se esperaba, encontramos diferencias estadísticamente significativas entre los tres tipos de docentes. Además, el modelo de dos factores del TBC se confirmó a través de un análisis factorial confirmatorio, proporcionando evidencia adicional de validez de la construcción. No obstante, también encontramos evidencia para abogar a favor de una solución de un factor. Los resultados del Omega de McDonald indicaron evidencia de confiabilidad. Estos hallazgos apoyan el uso de TBC en la evaluación formativa de los docentes en Brasil.

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.

The association between recreational cannabis use and posttraumatic stress disorder: A systematic review and methodological critique of the literature.

BACKGROUND: Given recent changes in the legal status of cannabis, the risks and benefits associated with its use have become an important public health topic. A growing body of research has demonstrated that posttraumatic stress disorder (PTSD) and recreational cannabis use (RCU) frequently co-occur, yet findings are inconsistent (e.g., direction of effect) and methodological variability makes comparison across studies difficult. METHODS: We conducted a comprehensive systematic review of all studies (N = 45) published before May 2020 regarding etiologic models of co-occurring RCU and PTSD, as well as provided a methodological critique to inform suggestions for future research initiatives. RESULTS: Findings indicate that a majority of studies (n = 37) demonstrated a significant association between RCU and PTSD. Findings provide evidence for the self-medication and high-risk models posited to explain co-occurring RCU and PTSD despite variability in assessment of RCU, which includes commonly used non-standardized self-report questions. CONCLUSION: The association between RCU and PTSD is likely bidirectional. Results inform clinicians and researchers working in the mental health and cannabis use fields how the variability in findings on the association between RCU and PTSD may be attributable, in part, to methodological issues that permeate the extant literature pertaining to RCU and PTSD.

The Influence of Clinician Gender and Attitudes on Judgments Related to Forensic Considerations in ICD-11 Paraphilic Disorders: An Internet-based Field Study

Aim: This study aimed to identify whether clinicians’ gender, clinical experience, and personal attitudes influenced their perception of criminality of specific sexual behaviours, their judgments about criminal liability if mentally disordered, and the need for treatment as part of criminal settings for those having ICD-11 paraphilic disorders. Method: In a secondary analysis of data only vignettes with the least (do not meet paraphilic disorder diagnostic requirements) and most extreme (met paraphilic disorder diagnostic requirements) descriptions of ICD-11 frotteuristic, coercive sexual sadism, and exhibitionistic arousal patterns and related behavior were randomly presented to participants. A total of 1,101 clinicians rated one to three vignettes (a total of 1,884) answering questions regarding diagnosis, criminal features, and their own attitudes. Results: The ICD-11 diagnostic guidelines were adequately used to distinguish paraphilic disorders from non-pathological arousal patterns.Vignette severity was the most important predictor for clinicians’ determination that a crime was committed. Results showed an interaction of the classification of paraphilic disorders, clinicians’ gender, and personal attitudes with judgments about concepts associated with criminality, criminal liability if a diagnosis was indicated, and the need for treatment in forensic settings. Conclusions: Increased formal education, clinical training about these disorders, and evidence-based treatment guidelines are required to avoid biases that may come from preconceived ideas and personal attitudes. Laws and policies that unnecessarily restrict the treatment of these patients in non-forensic settings—for example, when the individual is distress about the arousal pattern but no crime has been committed—should be examined.

Objetivo: Se diseñó un estudio con el objetivo de identificar si el género, la experiencia clínica y las actitudes personales de los clínicos influyen en su percepción de la criminalidad de conductas sexuales concretas, sus juicios sobre la responsabilidad criminal en evaluaciones forenses en presencia de un trastorno mental y con la necesidad de tratamiento para aquellos que tienen un trastorno parafílico de la CIE-11. Método: En un análisis secundario de los datos, se presentaron al azar viñetas con una descripción mínima (no cumple con los requisitos diagnósticos para un trastorno parafílico) y una descripción completa (cumple con los requisitos diagnósticos para un trastorno parafílico) de los patrones de excitación froteurismo, sadismo sexual coercitivo, exhibicionismo y conductas relacionadas de la CIE-11. Un total de 1,101 clínicos calificaron de una a tres viñetas (un total de 1,884) respondiendo a preguntas sobre el diagnóstico, las características criminales y sus propias actitudes. Resultados: Las guías diagnósticas de la CIE-11 fueron adecuadamente utilizadas por los clínicos para distinguir los trastornos parafílicos de los patrones de excitación no patológicos. La gravedad de la viñeta fue el predictor más importante para la determinación de los clínicos de que se había cometido un delito. Los resultados mostraron una interacción de la clasificación de los trastornos parafílicos, el género de los clínicos y las actitudes personales con los juicios sobre conceptos asociados con la criminalidad, la responsabilidad criminal en presencia de un trastorno mental y la necesidad de tratamiento en contextos de evaluación forenses. Conclusiones: Se requiere mayor educación formal, entrenamiento clínico sobre estos trastornos y guías de tratamiento basadas en evidencia para evitar sesgos que puedan provenir de ideas preconcebidas y actitudes personales.

The initiation or continuation of mental health services in the transition to college.

Objective: To examine what factors impact college students in the United States who are deciding to initiate or continue mental health services. Participants: Spring 2021 undergraduate students (N = 453) at a large urban university. Methods: Online, cross-sectional survey with mental health service experience as the independent variable and social support, accessibility, attitudes toward mental health, mental health literacy, and trust of mental health professionals as the dependent variables, as well as thematic analysis of reasons to discontinue services. Results: Individuals with lower levels of social support and higher levels of mental health literacy were more likely to have received therapy. Participants tended to discontinue services because of negative experiences, accessibility problems, negative attitudes toward services, or they felt better. Conclusions: Mental health literacy, social support, and accessibility are significant predictors of college student service use and should be taken into consideration by university administration.

Analysis of Mental Health Workforce: Implications for Social Work Practice and Profession.

This analysis was undertaken to better understand what factors may contribute to the relative strength or weakness of the clinical social work professional workforce. We explored the relationship between social work workforce numbers and social work licensure laws/policies. We also examined relationships between population factors and mental health workforce, including examining ratios of other mental health professions nationwide. Additionally, we explored mental health workforce strengths as it relates to state mental health needs and utilization of mental health services. Our findings were consistent with past research with respect to proportion of overall mental health workforce across mental health professionals. We did not find a direct relationship between licensure laws/policies and state social work workforce numbers. However, we found some relationships between the ratio of social workers to the population and state health rank, as well as the overall mental health workforce availability in a state. In addition, a relationship was found between ratio of social workers to the population and adults with mental illness not receiving care. Given the results, the authors posit that these findings could be used to promote the social work discipline in targeted ways, such as promotion of the discipline in states where mental health needs are underserved or in states with lower health rankings. Factors to consider at the macro and micro levels, as well as interprofessional issues in training and work, are discussed. We believe the findings from this analysis can be used to inform policy and promote the discipline of social work.

Validity of Categories Related to Gender Identity in ICD-11 and DSM-5 Among Transgender Individuals who Seek Gender-Affirming Medical Procedures / Validez de las categorías relacionadas con la identidad de género en la CIE-11 y el DSM-5 entre personas transgénero que buscan procedimientos médicos que afirmen su género

Background/Objective The most recent versions of the two main mental disorders classifications—the World Health Organization's ICD-11 and the American Psychiatric Association's DSM–5—differ substantially in their diagnostic categories related to transgender identity. ICD-11 gender incongruence (GI), in contrast to DSM-5 gender dysphoria (GD), is explicitly not a mental disorder; neither distress nor dysfunction is a required feature. The objective was compared ICD-11 and DSM-5 diagnostic requirements in terms of their sensitivity, specificity, discriminability and ability to predict the use of gender-affirming medical procedures. Method A total of 649 of transgender adults in six countries completed a retrospective structured interview. Results Using ROC analysis, sensitivity of the diagnostic requirements was equivalent for both systems, but ICD-11 showed greater specificity than DSM-5. Regression analyses indicated that history of hormones and/or surgery was predicted by variables that are an intrinsic aspect of GI/GD more than by distress and dysfunction. IRT analyses showed that the ICD-11 diagnostic formulation was more parsimonious and contained more information about caseness than the DSM-5 model. Conclusions This study supports the ICD-11 position that GI/GD is not a mental disorder; additional diagnostic requirements of distress and/or dysfunction in DSM-5 reduce the predictive power of the diagnostic model

Antecedentes/Objetivo Las versiones más recientes de las clasificaciones de trastornos mentales —CIE-11 de la Organización Mundial de la Salud y DSM–5 de la Asociación Psiquiátrica Americana— difieren en sus categorías diagnósticas relacionadas con la identidad transgénero. La discordancia de género (DiscG) de la CIE-11, en contraste con la disforia de género (DisfG) del DSM-5, no es considerada un trastorno mental; el distrés y la disfunción no son características requeridas para el diagnóstico. El objetivo fue comparar los requisitos diagnósticos de la CIE-11 y el DSM-5 en términos de sensibilidad, especificidad y capacidad para discriminar casos y predecir el uso de procedimientos médicos de afirmación de género. Método 649 adultos transgénero de seis países completaron una entrevista estructurada retrospectiva. Resultados De acuerdo con el análisis ROC, la sensibilidad de ambos sistemas fue equivalente, aunque la CIE-11 mostró mayor especificidad que el DSM-5. Los análisis de regresión indicaron que la historia de uso de hormonas o cirugía se predijo por variables intrínsecas a la DiscG/DisfG y no por el distrés o disfunción. Según los análisis de respuesta al ítem (TRi) la formación CIE-11 resulta más parsimoniosa y contiene mayor información sobre los casos. Conclusiones Se aporta evidencia a favor de que la DiscG/DisfG no es un trastorno mental; los criterios diagnósticos adicionales de distrés y/o disfunción del DSM-5 reducen su poder predictivo.

Evaluating the measurement invariance of the Personality Inventory for DSM-5 (PID-5) in Black Americans and White Americans.

The Personality Inventory for the DSM-5 (PID-5) assesses the five pathological personality trait domains that comprise the descriptive core of the DSM-5 Alternative Model of Personality Disorders (AMPD). The PID-5 five-domain factor structure is aligned with the AMPD and is reported as replicable across samples in the U.S., in other countries, and in different languages. In this study, the PID-5 factor structure is examined in two distinct racial groups within the U.S.-White Americans (WA) and Black Americans (BA). Student participants from four universities in the U.S. (N = 1,834)-composed of groups of WA (n = 1,274) and BA (n = 560)-were proportionally parsed into derivation and replication subsamples. The "traditional" PID-5 five-factor structure emerged for the WA group in the derivation subsample and was subsequently confirmed in the WA replication subsample. In the BA group derivation subsample, a single-factor solution emerged, which was also confirmed in the BA replication sample. This single-factor solution in the BA group reflects large shared covariation across all pathological personality domains, suggesting an undifferentiated, broadly based level of demoralization represented by the item pool of the PID-5. We argue that this structure can be construed as mirroring a racialized and prejudice-based living experience for many BAs in a predominantly non-Black society. Based on the results with the samples employed in the present study, we conclude that the PID-5 is not an equivalent measure of pathological personality traits across Black Americans and White Americans.

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.

Can Clinicians Use Dimensional Information to Make a Categorical Diagnosis of Paraphilic Disorders? An ICD-11 Field Study.

BACKGROUND: The diagnosis of paraphilic disorder is a complicated clinical judgment based on the integration of information from multiple dimensions to arrive at a categorical (present/absent) conclusion. The recent update of the guidelines for paraphilic disorders in ICD-11 presents an opportunity to investigate how mental health professionals use the diagnostic guidelines to arrive at a diagnosis which thereby can optimize the guidelines for clinical use. AIM: This study examined clinicians' ability to use the ICD-11 diagnostic guidelines for paraphilic disorders which contain multiple dimensions that must be simultaneously assessed to arrive at a diagnosis. METHODS: The study investigated the ability of 1,263 international clinicians to identify the dimensions of paraphilic disorder in the context of written case vignettes that varied on a single dimension only. OUTCOMES: Participants provided diagnoses for the case vignettes along with dimensional ratings of the degree of presence of five dimensions of paraphilic disorder (arousal, consent, action, distress, and risk). RESULTS: Across a series of analyses, clinicians demonstrated a clear ability to recognize and appropriately integrate the dimensions of paraphilic disorders; however, there was some evidence that clinicians may over-diagnose non-pathological cases. CLINICAL TRANSLATION: Clinicians would likely benefit from targeted training on the ICD-11 definition of paraphilic disorder and should be cautious of over-diagnosing. STRENGTHS AND LIMITATIONS: This study represents a large international sample of health professionals and is the first to examine clinicians' ability to apply the ICD-11 diagnostic guidelines for paraphilic disorders. Important limitations include not generalizing to all clinicians and acknowledging that results may be different in direct clinical interactions vs written case vignettes. CONCLUSION: These results indicate that clinicians appear capable of interpreting and implementing the diagnostic guidelines for paraphilic disorders in ICD-11. Keeley JW, Briken P, Evans SC, et al.

Taxonomy and utility in the diagnostic classification of mental disorders.

OBJECTIVE: One strategy for improving the clinical utility of mental health diagnostic systems is to better align them with how clinicians conceptualize psychopathology in practice. This approach was used in International Classification of Diseases 11th Revision (ICD-11) development, but its underlying assumption-a link between taxonomic "fit" and clinical utility-remains untested. METHODS: Using data from global mental health clinician samples (combined N = 5404), we investigated the association between taxonomic fit and clinical utility in mental disorder categories. RESULTS: The overall association between fit and utility was positive (r = 0.19) but statistically not different from zero (95% confidence interval [CI]: -0.06, 0.43) in this small sample (N = 39 ICD/DSM categories). However, a positive association became clear after correcting for outliers (r = 0.34 [0.05, 0.58] or higher). Further insights were apparent for specific diagnoses given their locations in the scatterplot. CONCLUSIONS: Results suggest a positive link between taxonomic fit and clinical utility in mental disorder diagnoses, highlighting future research directions.

Diagnostic classification of irritability and oppositionality in youth: a global field study comparing ICD-11 with ICD-10 and DSM-5.

BACKGROUND: Severe irritability has become an important topic in child and adolescent mental health. Based on the available evidence and on public health considerations, WHO classified chronic irritability within oppositional defiant disorder (ODD) in ICD-11, a solution markedly different from DSM-5's (i.e. the new childhood mood diagnosis, disruptive mood dysregulation disorder [DMDD]) and from ICD-10's (i.e. ODD as one of several conduct disorders without attention to irritability). In this study, we tested the accuracy with which a global, multilingual, multidisciplinary sample of clinicians were able to use the ICD-11 classification of chronic irritability and oppositionality as compared to the ICD-10 and DSM-5 approaches. METHODS: Clinicians (N = 196) from 48 countries participated in an Internet-based field study in English, Spanish, or Japanese and were randomized to review and use one of the three diagnostic systems. Through experimental manipulation of validated clinical vignettes, we evaluated how well clinicians in each condition could identify chronic irritability versus nonirritable oppositionality, episodic bipolar disorder, dysthymic depression, and normative irritability. RESULTS: Compared to ICD-10 and DSM-5, ICD-11 led to more accurate identification of severe irritability and better differentiation from boundary presentations. Participants using DSM-5 largely failed to apply the DMDD diagnosis when it was appropriate, and they more often applied psychopathological diagnoses to developmentally normative irritability. CONCLUSIONS: The formulation of irritability and oppositionality put forth in ICD-11 shows evidence of clinical utility, supporting accurate diagnosis. Global mental health clinicians can readily identify ODD both with and without chronic irritability.

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.
