Abstract Objective To describe translation to Spanish and Portuguese and adaptation of the Mental Illness Clinicians’ Attitudes Scale version 4 (MICA v4). Methods The questionnaire was administered to primary care physicians (PCPs) from four Latin-American countries, Brazil, Bolivia, Chile, and Cuba. The validation process included four phases: 1) translation of the questionnaire to Spanish and Portuguese; 2) assessment of face validity; 3) assessment of reliability; and 4) evaluation of construct validity with confirmatory factor analysis (CFA). Results The study sample comprised 427 PCPs. The mean age of the Spanish-speaking sample (n = 252) was 40.1 (S.D = 9.7) years and the mean age of the Portuguese-speaking sample (n = 150) was 40.2 (S.D = 10.9) years. Both models demonstrated “appropriate” internal reliability. Total omega was 0.91 for the Spanish-speaking sample and 0.89 for the Portuguese-speaking sample. The CFA of both questionnaires showed an appropriate fit for a three-factor model (Portuguese: CFI = 0.927; TLI = 0.913; RMSEA = 0.066; Spanish: CFI = 0.945; TLI = 0.935; RMSEA = 0.068). Conclusion The Latin-American versions of the MICA v4 in Spanish and Brazilian Portuguese have appropriate psychometric properties, good internal consistency, and are applicable to and acceptable in the Latin-American context. The instrument proved its validity for collecting data on stigmatizing attitudes among health professionals in different contexts and cultures.

Objective: The Identifying Depression Early in Adolescence Risk Score (IDEA-RS) was recently developed in Brazil using data from the Pelotas 1993 Birth Cohort to estimate the individualized probability of developing depression in adolescence. This model includes 11 sociodemographic variables and has been assessed in longitudinal studies from four other countries. We aimed to test the performance of IDEA-RS in an independent, community-based, school-attending sample within the same country: the Brazilian High-Risk Cohort. Methods: Standard external validation, refitted, and case mix-corrected models were used to predict depression among 1442 youth followed from a mean age of 13.5 years at baseline to 17.7 years at follow-up, using probabilities calculated with IDEA-RS coefficients. Results: The area under the curve was 0.65 for standard external validation, 0.70 for the case mix-corrected model, and 0.69 for the refitted model, with discrimination consistently above chance for predicting depression in the new dataset. There was some degree of miscalibration, corrected by model refitting (calibration-in-the-large reduced from 0.77 to 0). Conclusion: IDEA-RS was able to parse individuals with higher or lower probability of developing depression beyond chance in an independent Brazilian sample. Further steps should include model improvements and additional studies in populations with high levels of subclinical symptoms to improve clinical decision making.

Objective: Obstacles for computational tools in psychiatry include gathering robust evidence and keeping implementation costs reasonable. We report a systematic review of automated speech evaluation for the psychosis spectrum and analyze the value of information for a screening program in a healthcare system with a limited number of psychiatrists (Maputo, Mozambique). Methods: Original studies on speech analysis for forecasting of conversion in individuals at clinical high risk (CHR) for psychosis, diagnosis of manifested psychotic disorder, and first-episode psychosis (FEP) were included in this review. Studies addressing non-verbal components of speech (e.g., pitch, tone) were excluded. Results: Of 168 works identified, 28 original studies were included. Valuable speech features included direct measures (e.g., relative word counting) and mathematical embeddings (e.g.: word-to-vector, graphs). Accuracy estimates reported for schizophrenia diagnosis and CHR conversion ranged from 71 to 100% across studies. Studies used structured interviews, directed tasks, or prompted free speech. Directed-task protocols were faster while seemingly maintaining performance. The expected value of perfect information is USD 9.34 million. Imperfect tests would nevertheless yield high value. Conclusion: Accuracy for screening and diagnosis was high. Larger studies are needed to enhance precision of classificatory estimates. Automated analysis presents itself as a feasible, low-cost method which should be especially useful for regions in which the physician pool is insufficient to meet demand.

Resumo: O suicídio entre adolescentes é um importante problema de saúde pública em nível global. O estudo teve como principal objetivo descrever os métodos de suicídio mais usados por adolescentes brasileiros entre 10 e 19 anos de idade, de 2006 a 2015. Foram obtidos dados completos do Departamento de Informática do SUS (DATASUS), codificados em sete categorias de métodos de suicídio. As seguintes análises estatísticas foram realizadas: testes de qui-quadrado (χ2) para examinar a associação entre a frequência de cada método de suicídio e o ano do óbito. As razões de chances (OR) e intervalos de 95% de confiança (IC95%) compararam as chances relativas entre homens e mulheres para cada método de suicídio. Durante o período analisado, houve 8.026 suicídios entre adolescentes. O enforcamento foi o método de suicídio mais usado em ambos os sexos eram (2015 = 70,3%), com um aumento mais agudo em mulheres (2015 = 65,82%). O uso proporcional de armas (2006 = 14,2%; 2015 = 9,1%) e envenenamento (2006 = 13,3%; 2015 = 9,2%) diminuiu ao longo do período. O aumento dos enforcamentos é preocupante, suscitando questões com dificuldades na imposição de barreiras de acesso e a alta letalidade desse método. Nesse contexto, precisa haver uma compreensão mais abrangente dos comportamentos suicidas entre os adolescentes brasileiros para informar as medidas preventivas em geral e, mais especificamente, para elucidar os motivos para o aumento dos suicídios por enforcamento.

Abstract: Suicide among adolescents has become a major public health problem worldwide. Our study sought to describe the most commonly used methods of suicide among adolescents aged 10 to 19 years in Brazil between 2006 and 2015. Complete data were obtained from the Brazilian Health Informatics Department (DATASUS) and coded into seven categories of suicide methods. The following statistical analyzes were performed: chi-square (χ2) tests to examine the association between the frequency of each suicide method and the year; odds ratios (OR) and 95% confidence intervals (95%CI) compared the relative chances of each suicide method occurring between boys and girls. In total, 8,026 suicides among Brazilian adolescents were registered over the analyzed period. The most commonly used method of suicide by both sexes was hanging (2015 = 70.3%), and the most significant increase was observed in girls (2015 = 65.82%). The proportional use of arms (2006 = 14.2%; 2015 = 9.1%) and poisoning (2006 = 13.3%; 2015 = 9.2%) decreased over the period. The increase in hanging is worrisome, mostly due to difficulties to impose access barriers and to its high lethality. In such context, a comprehensive understanding of suicide behaviors among adolescents in Brazil should be drawn to inform general prevention measures and, more specifically, the reasons for the increase in hanging need to be further investigated.

Resumen: El suicidio entre adolescentes se ha convertido en un importante problema de salud pública en todo el mundo. El objetivo de este estudio fue describir los métodos de suicido usados más comúnmente entre adolescentes, con edades comprendidas entre los 10 y 19 años, en Brasil desde 2006 hasta 2015. Los datos completos se obtuvieron del Departamento de Informática del Sistema Único de Salud (DATASUS) y se codificaron en siete categorías de métodos de suicidio. Se realizaron análisis estadísticos: tests chi-cuadrado (χ2) para examinar la asociación entre la frecuencia de cada método de suicidio y año. Odds ratios (OR) y los intervalos del 95% de confianza (IC95%) compararon las oportunidades relativas de cada método suicidio que se produce entre hombres y mujeres. Se registraron 8.026 suicidios entre adolescentes brasileños durante el período analizado. El método de suicidio más comúnmente usado por ambos sexos fue ahorcamiento (2015 = 70,3%), se observó un aumento más pronunciado en mujeres (2015 = 65,82%). El uso proporcional de armas (2006 = 14,2%; 2015 = 9,1%) y envenenamiento (2006 = 13,3%; 2015 = 9,2%) descendió durante este período. El incremento por ahorcamiento es preocupante, principalmente, en lo que se refiere a las dificultades para imponer barreras de acceso, así como por su alta letalidad. En este contexto, se deberían describir más los comportamientos suicidas entre adolescentes en Brasil para comprenderlos mejor, con el fin de que se tomen medidas de prevención general y, más específicamente, se profundice en las razones del incremento de ahorcamientos.

Objective: To examine suicide rates among adolescents from six large cities in Brazil and to analyze the relationship between adolescent suicide rates and socioeconomic indicators between 2006 and 2015. Methods: Generalized estimating equation models were used to assess the impact of socioeconomic factors – including social inequality and unemployment rates – on adolescent suicide rates. Results: The rate of adolescent suicide increased by 24% over the course of the study period. Social inequality (assessed using the Gini index), was positively associated with overall adolescent suicide rates (β = 10.68; 95%CI = 2.32-19.05; p ≤ 0.012). After disaggregating the findings by age (10-14 and 15-19 years), social inequality was associated with suicide rate only for adolescents aged 15-19 years (β = 9.63; 95%CI = 2.31-16.96; p ≤ 0.005). Disaggregating these findings by sex, the association with economic variables became significant only among females. Males had a higher overall suicide rate than females, and the highest rate was observed in male adolescents aged 15-19 years. Higher levels of unemployment were associated with higher suicide rates. Conclusion: Our findings suggest that socioeconomic indicators, particularly unemployment and social inequality, are relevant social determinants of suicide in adolescence.

Objective: Disorders characterized by “distressing unexplained somatic symptoms” are challenging. In the ICD-11 Primary Health Care (PHC) Guidelines for Diagnosis and Management of Mental Disorders (ICD-11 PHC), a new category, bodily stress syndrome (BSS), was included to diagnose patients presenting unexplained somatic symptoms. The present study investigated the association of BSS with anxiety, depression, and four subgroups of physical symptoms in a Brazilian primary health care (PHC) sample. Methodology: As part of the international ICD-11 PHC study, 338 patients were evaluated by their primary care physicians, followed by testing with Clinical Interview Schedule (CIS-R) and World Health Organization Disability Assessment Schedule, Version 2.0 (WHODAS 2.0). BSS was diagnosed in the presence of at least three somatic symptoms associated with incapacity. The association between anxiety, depression, and four subgroups of physical symptoms with being a BSS case was analyzed. Results: The number of somatic symptoms was high in the overall sample of 338 patients (mean = 8.4), but even higher in the 131 BSS patients (10.2; p < 0.001). Most BSS patients (57.3%) had at least three symptoms from two, three, or four subgroups, and these were associated with anxiety and depression in 80.9% of these patients. The symptom subgroup most strongly associated with “being a BSS” case was the non-specific group (OR = 6.51; 95%CI 1.65-24.34), followed by musculoskeletal (OR = 2,31; 95%CI 1.19-4.72). Conclusion: Somatic symptoms were frequent in a sample of PHC patients in Brazil. In the present sample, one third were BSS cases and met the criteria for at least two symptom subgroups, supporting the hypothesis that different functional symptoms are related to each other.
