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.

Innovations and changes in the ICD-11 classification of mental, behavioural and neurodevelopmental disorders.

Following approval of the ICD-11 by the World Health Assembly in May 2019, World Health Organization (WHO) member states will transition from the ICD-10 to the ICD-11, with reporting of health statistics based on the new system to begin on January 1, 2022. The WHO Department of Mental Health and Substance Abuse will publish Clinical Descriptions and Diagnostic Guidelines (CDDG) for ICD-11 Mental, Behavioural and Neurodevelopmental Disorders following ICD-11's approval. The development of the ICD-11 CDDG over the past decade, based on the principles of clinical utility and global applicability, has been the most broadly international, multilingual, multidisciplinary and participative revision process ever implemented for a classification of mental disorders.

Global Collaborative Team Performance for the Revision of the International Classification of Diseases: A Case Study of the World Health Organization Field Studies Coordination Group.

: Collaborative teamwork in global mental health presents unique challenges, including the formation and management of international teams composed of multicultural and multilingual professionals with different backgrounds in terms of their training, scientific expertise, and life experience. The purpose of the study was to analyze the performance of the World Health Organization (WHO) Field Studies Coordination Group (FSCG) using an input-processes-output (IPO) team science model to better understand the team's challenges, limitations, and successes in developing the eleventh revision of the International Classification of Diseases (ICD). : We thematically analyzed a collection of written texts, including FSCG documents and open-ended qualitative questionnaires, according to the conceptualization of the input-processes-output model of team performance.

Renaming schizophrenia.

The movement towards renaming of schizophrenia in Japan started in 1993 upon receipt of a letter by The National Federation of Families with Mentally Ill in Japan addressed to the board of Japanese Society of Psychiatry of Neurology (JSPN), requesting to rename schizophrenia as the then-official term for the condition, Seishin-Bunretsu-Byo, or 'mind-splitting disease', was humiliating. A committee was established within JSPN to address the issue, public comments were collected, a new name 'Togo-Shitcho-Sho' ('disintegration disorder') was approved in 2002, and in 2005, the new name was adopted in the Revised Mental Health and Welfare Act. This paper describes the process of renaming, and also the current situation in Korea, Taiwan, China, Hong Kong and Malaysia, where Chinese characters are used.

Clinical utility of ICD-11 diagnostic guidelines for high-burden mental disorders: results from mental health settings in 13 countries.

In this paper we report the clinical utility of the diagnostic guidelines for ICD-11 mental, behavioural and neurodevelopmental disorders as assessed by 339 clinicians in 1,806 patients in 28 mental health settings in 13 countries. Clinician raters applied the guidelines for schizophrenia and other primary psychotic disorders, mood disorders (depressive and bipolar disorders), anxiety and fear-related disorders, and disorders specifically associated with stress. Clinician ratings of the clinical utility of the proposed ICD-11 diagnostic guidelines were very positive overall.

The ICD-11 developmental field study of reliability of diagnoses of high-burden mental disorders: results among adult patients in mental health settings of 13 countries.

Reliable, clinically useful, and globally applicable diagnostic classification of mental disorders is an essential foundation for global mental health. The World Health Organization (WHO) is nearing completion of the 11th revision of the International Classification of Diseases and Related Health Problems (ICD-11). The present study assessed inter-diagnostician reliability of mental disorders accounting for the greatest proportion of global disease burden and the highest levels of service utilization - schizophrenia and other primary psychotic disorders, mood disorders, anxiety and fear-related disorders, and disorders specifically associated with stress - among adult patients presenting for treatment at 28 participating centers in 13 countries.

Categories that should be removed from mental disorders classifications: perspectives and rationales of clinicians from eight countries.

Objective: To explore the rationales of mental health professionals (mainly psychiatrists and psychologists) from 8 countries for removing specific diagnostic categories from mental disorders classification systems.

Method: As part of a larger study, 505 participants indicated which of 60 major disorders should be omitted from mental disorders classification systems and provided rationales. Rationale statements were analyzed using inductive content analysis.

[Recent development of the ICD-11 focusing on the draft of its linear structure].

I overviewed the draft of the linear structure (22nd May, 2013) of the International Statistical Classification of Diseases and Related Health Problems, Eleventh Revision. In this draft, sleep and sexual disorders were not included in mental and behavioural disorders. The World Health Organization decided not to regard them as mental disorders.

Mental health professionals' natural taxonomies of mental disorders: implications for the clinical utility of the ICD-11 and the DSM-5.

Objective: To examine the conceptualizations held by psychiatrists and psychologists around the world of the relationships among mental disorders in order to inform decisions about the structure of the classification of mental and behavioral disorders in World Health Organization's International Classification of Diseases and Related Health Problems 11th Revision (ICD-11).

Method: 517 mental health professionals in 8 countries sorted 60 cards containing the names of mental disorders into groups of similar disorders, and then formed a hierarchical structure by aggregating and disaggregating these groupings. Distance matrices were created from the sorting data and used in cluster and correlation analyses.

[Recent progress of the ICD-11].

The ICD-11 is being developed for publication in 2015, while another important diagnostic classification system, the DSM-5, is being finalized and prepared for publication in 2013. This paper provided an overview of the revision process and also the current status of the drafts of both systems. In addition, the Global Clinical Practice Network, an online network created by the WHO for clinicians throughout the world to participate in the revision efforts for the ICD-11 by reviewing the proposals, providing feedback on them, and participating in field trials, is introduced.

A global clinicians' map of mental disorders to improve ICD-11: analysing meta-structure to enhance clinical utility.

Enhancing clinical utility is an emphasis of the World Health Organization's development of the mental and behavioural disorders chapter of the next International Classification of Diseases (ICD-11). Understanding how clinicians conceptualize the structure of mental disorders can enable a more clinically intuitive classification architecture that will help professionals find the categories they need more efficiently. This study examined clinicians' conceptualizations of the relationships among mental disorders and the dimensions they use in making these judgements.

Schizo-nomenclature: a new condition?

Some psychiatric diagnoses are stigmatic. In August of 2002, at the annual congress of the Japanese Society of Psychiatry and Neurology, the Society decided to change the name of schizophrenia in Japanese from seishinbunretsu-byo ('split mind disease') to togoshitcho-sho ('loss of coordination disorder'). In 2006 a survey was carried out among the 80 members of the Section on Classification, Diagnostic Assessment and Nomenclature of the World Psychiatric Association.

Relationship of nurse burnout with personality characteristics and coping behaviors.

Burnout of nurses at university hospitals was analyzed in relation to their personality characteristics and coping behaviors. A self-administered questionnaire regarding burnout (the Copenhagen Burnout Inventory), work-related stressors (the Nursing Job Stressor Scale), personality characteristics (Short-Form Eysenck Personality Questionnaire-Revised), and coping behaviors (the short Japanese version of Brief COPE) was used. We obtained answers from 778 nurses (response rate: 94.

Reliability and validity of the Japanese version of the Anxiety Sensitivity Index.

This preliminary study evaluated the reliability and validity of the Japanese version of the Anxiety Sensitivity Index (ASI). Its test-retest reliability and internal consistency were found acceptable. Factor analysis of the ASI yielded 4 anxiety-related factors: factor I is heart/lung failure concern; factor II, psychological concern; factor III, physical concern; and factor IV, social concern.

Factor structure of the Dimensional Assessment of Personality Pathology-Basic Questionnaire and its relationship with the revised NEO personality inventory in a Japanese sample.

The Dimensional Assessment of Personality Pathology, Basic Questionnaire (DAPP-BQ) was developed to assess 18 personality traits that provide a systematic representation of personality disorder. This study investigates the reliability and validity of the Japanese version of the DAPP-BQ and the relationship between the DAPP-BQ and Revised NEO Personality Inventory (NEO-PI-R) in a heterogeneous general population sample (n = 1485). Internal consistency (coefficient alpha) and test-retest reliability over a 3-week period was satisfactory for all scales.
