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.

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. A concurrent joint-rater design was used, focusing specifically on whether two clinicians, relying on the same clinical information, agreed on the diagnosis when separately applying the ICD-11 diagnostic guidelines. A total of 1,806 patients were assessed by 339 clinicians in the local language. Intraclass kappa coefficients for diagnoses weighted by site and study prevalence ranged from 0.45 (dysthymic disorder) to 0.88 (social anxiety disorder) and would be considered moderate to almost perfect for all diagnoses. Overall, the reliability of the ICD-11 diagnostic guidelines was superior to that previously reported for equivalent ICD-10 guidelines. These data provide support for the suitability of the ICD-11 diagnostic guidelines for implementation at a global level. The findings will inform further revision of the ICD-11 diagnostic guidelines prior to their publication and the development of programs to support professional training and implementation of the ICD-11 by WHO member states.
Substance use is a major cause of disability globally. This has been recognized in the recent United Nations Sustainable Development Goals (SDGs), in which treatment coverage for substance use disorders is identified as one of the indicators. There have been no estimates of this treatment coverage cross-nationally, making it difficult to know what is the baseline for that SDG target. Here we report data from the World Health Organization (WHO)'s World Mental Health Surveys (WMHS), based on representative community household surveys in 26 countries. We assessed the 12-month prevalence of substance use disorders (alcohol or drug abuse/dependence); the proportion of people with these disorders who were aware that they needed treatment and who wished to receive care; the proportion of those seeking care who received it; and the proportion of such treatment that met minimal standards for treatment quality ("minimally adequate treatment"). Among the 70,880 participants, 2.6% met 12-month criteria for substance use disorders; the prevalence was higher in upper-middle income (3.3%) than in high-income (2.6%) and low/lower-middle income (2.0%) countries. Overall, 39.1% of those with 12-month substance use disorders recognized a treatment need; this recognition was more common in high-income (43.1%) than in upper-middle (35.6%) and low/lower-middle income (31.5%) countries. Among those who recognized treatment need, 61.3% made at least one visit to a service provider, and 29.5% of the latter received minimally adequate treatment exposure (35.3% in high, 20.3% in upper-middle, and 8.6% in low/lower-middle income countries). Overall, only 7.1% of those with past-year substance use disorders received minimally adequate treatment: 10.3% in high income, 4.3% in upper-middle income and 1.0% in low/lower-middle income countries. These data suggest that only a small minority of people with substance use disorders receive even minimally adequate treatment. At least three barriers are involved: awareness/perceived treatment need, accessing treatment once a need is recognized, and compliance (on the part of both provider and client) to obtain adequate treatment. Various factors are likely to be involved in each of these three barriers, all of which need to be addressed to improve treatment coverage of substance use disorders. These data provide a baseline for the global monitoring of progress of treatment coverage for these disorders as an indicator within the SDGs.
Excess mortality in persons with severe mental disorders (SMD) is a major public health challenge that warrants action. The number and scope of truly tested interventions in this area remain limited, and strategies for implementation and scaling up of programmes with a strong evidence base are scarce. Furthermore, the majority of available interventions focus on a single or an otherwise limited number of risk factors. Here we present a multilevel model highlighting risk factors for excess mortality in persons with SMD at the individual, health system and socio-environmental levels. Informed by that model, we describe a comprehensive framework that may be useful for designing, implementing and evaluating interventions and programmes to reduce excess mortality in persons with SMD. This framework includes individual-focused, health system-focused, and community level and policy-focused interventions. Incorporating lessons learned from the multilevel model of risk and the comprehensive intervention framework, we identify priorities for clinical practice, policy and research agendas.

Abstract: In facilitating the presence of risk behaviors for health, some conditions inherent to the gastronomical and hotel industry may significantly affect the people working in this market. Among them are non-regular working days, temporary employment, law salaries, problems at work, low professional prestige, minimum development opportunities, bad relationships with managers, and unsafe conditions in the job environment. In comparison with other work areas, this is one of the sectors with higher risk of problems related to alcohol use, mainly due to the availability of the substance in the work place, to the social pressure, to the working schedules, and to the way people cope with stress at work. Due to movements, rhythm, and techniques used in the activities performed in this kind of job, it is possible to develop bones and muscles alterations, and because of constant changes in labor shifts circadian cycles suffer disruptions that lead to different somatic symptomatologies. Studies in workers have shown that problematic alcohol consumption is present in 33-44% of this population. Other studies have found prevalences up to 24% of mental disorders in workers. The Department of Labor has reported that, as part of work diseases, mental and behavioral disorders increased its prevalence of 0.3% in 1999 to 1.9% in 2003. On the other hand, some studies report an association between mental disorders, somatization, and alcohol use in general population. People spend a considerable portion of their lives at their work places and working in gastronomic and hotel industry implies high risk for health. The objective of this paper is to know the association among alcohol use, the number of symptoms regarding mental health problems, and the level of discomfort caused by somatic symptoms in a sample of gastronomic and hotel industry workers from Mexico City. Material and method Population and sample Sampling was non-random, on convenience, and by quota. The sample included 194 men, over 18 years old, who were working at companies from the gastronomic and hotel industry in Mexico City. Most of the subjects were under 45 years old, over half of them studied until junior high school. The most frequent position among the subjects was waiter. Working days vary, depending on the day and time banquets and receptions are programmed. Over two thirds of the subjects mentioned having three or less years working in this kind of job. Questionnaire The short version of the AUDIT (first three questions) was used to establish the level of alcohol use. This version allows to rate subjects in three levels, according to the amount and frequency of consumption: low risk use, risk use, and dangerous use. The five-item Mental Health Inventory (MHI-5) was used to determine the presence of mental health problems. The MHI-5 is a screening test that measures non-psychotic affective disorders, according to DSM-IV criteria, with no reference to specific disorders. The Symptoms Check List-90 (SCL-90) was used to identify psychological stress derived from somatic symptoms. The three scales have good levels of reliability and validity. The field team talked to the managers of the training department at the union, because all the subjects in the sample were affiliated, to get permission to collect the information. No invasive techniques were used nor any other type of intervention. Subjects responded to the questionnaire gathered in groups inside a training room. The fieldwork involved trained interviewers, whose training was voluntary. All the workers accepted to participate and to respond the questionnaire through a verbal agreement. Participation was anonymous and neither the union representatives nor the managers had access to individual questionnaires, which granted confidentiality. The union representatives acknowledged a global report that intended to make them aware of the magnitude of the alcohol use and mental health problems among their affiliates. SPSS 10 software was used to analyze data. Results A total of 44.2% of the subjects reported drinking four or more drinks per occasion; 60.9% of them mentioned they had drunk six or more drinks per occasion during the last year; 55.5% of the workers were located in a low risk consumption level; 43.1% had a risky consumption level, and 10.4% consumed at a dangerous level. Results regarding mental health showed that a quarter of the subjects «have felt uneasy¼ (26.1%), 16.7% «have felt happy¼, 9.7% «have felt sad and melancholic¼, 8.4% «have felt down or as if nothing could cheer them up¼, and 4.3% «have been very nervous¼. A cut-off score of 16 or higher allowed identifying 11% of cases with symptoms of a possible mental health problem. Most of the subjects (69.6%) mentioned having experienced at least one somatic symptom during the last month. The ones that caused more discomfort were muscular pain (17.6%), backaches (12%), headaches (9.7%), weakness in some part of the body (7.1%), and nausea (6.7%). A cut-off score of eight or higher allowed to identify 14.7% of cases with somatic symptomatology that caused psychological distress. A Pearson correlation analysis was performed and the results showed a significant association between the level of alcohol consumption and the discomfort due to somatic symptoms (pr=.404^><.01). Significant associations were also found between the mental health state and the discomfort due to somatic symptoms (pr=.339 ^><.01), and between the level of alcohol consumption and the mental health state (pr=.260 ^><.01). Discussion and conclusions The percentage of alcohol consumers, the amount of alcohol consumed, the frequency of consumption, and the prevalence of problematic consumption were higher in this group of workers when compared to employees from other occupations. This can be the result of a mayor substance availability within gastronomic and hotel work environments. The association between alcohol use and the number of symptoms of mental health problems may be an indicator of co-morbidity between both conditions. It is also possible that the association is related to excessive alcohol use as a way to cope with emotional problems. The somatic symptoms with the highest prevalence were part of the somatization scale, but there is a possibility that they are indicators of an illness or disease derived from the labor activity instead of indicators of somatic symptoms. On the other hand, whether alcohol use increases frequency of mental and physical troubles or that consumption is present as a reaction to these troubles, more research is necessary to know more about these variables co-morbidity because these relate to the presence of accidents, problems at work, social and family problems, as well as economic burden. The use of screening scales in working settings is important because it reduces costs and helps to identify related problems. In addition, they are easy to use at factories and businesses without interfering with the manufacturing processes. Nevertheless, it is important to use more specific instruments with identified cases. This would permit a more precise diagnosis and, if necessary, to refer subjects to institutions that provide specialized health care. To have such a structure would reinforce protective factors for subjects to cope with the risks inherent to their professional activity. Limitations and suggestions Conclusions are valid only for the workers in this sample because of the sampling method and they cannot be applied to all the workers of the gastronomic and hotel industry. So far, studies about substance use in working settings have focused on men population; however, women are an important segment that researchers should consider investigating to collect information that can sustain proper and necessary actions.
