A behavioral economic risk aversion experiment in the context of the COVID-19 pandemic.

We investigated what degree of risk of infection with COVID-19 is necessary so that people intend to stay home, even when doing so means losing their salary. We conducted an online survey across Brazil during the initial outbreak, in which 8,345 participants answered a questionnaire designed to identify the maximum tolerated risk (k') necessary for them to disregard social distancing recommendations and guarantee their salaries. Generalized linear mixed models, path analysis structural equation, and conditional interference classification tree were performed to further understand how sociodemographic factors impact k' and to establish a predictive model for the risk behavior of leaving home during the pandemic. We found that, on average, people tolerate 38% risk of infection to leave home and earn a full salary, but this number decreased to 13% when the individual risk perception of becoming ill from severe acute respiratory syndrome coronavirus-2 is considered. Furthermore, participants who have a medium-to-high household income and who are older than 35 years are more likely to be part of the risk-taking group who leave home regardless of the potential COVID-19 infection level; while participants over 45 years old and with good financial health are more likely to be part of the risk-averse group, who stay home at the expense of any salary offered. Our findings add to the political and public debate concerning lockdown strategies by showing that, contrary to supposition, people with low socioeconomic status are not more likely to ignore social distancing recommendations due to personal economic matters.

The influence of geographical and economic factors in estimates of childhood abuse and neglect using the Childhood Trauma Questionnaire: A worldwide meta-regression analysis.

This multilevel meta-analysis examined the effects of geographical and economic factors on worldwide childhood maltreatment estimates measured by the Childhood Trauma Questionnaire (CTQ) short-form. The primary outcome extracted was continuous scores on the CTQ subscales - emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect - and total score. Geographical, economical and methodological variables were extracted for use as covariates in meta-regression models. A literature search identified 288 studies suitable for the CTQ total score analysis (N=59,692) and 189 studies suitable for maltreatment subtype analysis (N=44,832). We found that Europe and Asia were associated with lower CTQ estimates while South America presented the highest estimates among continents. Specifically, studies from China, Netherlands and United Kingdom presented the lowest maltreatment estimates. Furthermore, high-income countries presented lower CTQ physical neglect estimates in comparison to low- or middle-income countries, while per-capita gross domestic product of countries was negatively associated with childhood physical neglect estimates. Despite the influence of methodological covariates, these findings indicate that geographical and economic factors could influence variations of childhood maltreatment estimates around the world, particularly when assessed by a structured standardized questionnaire.

Propriedades psicométricas da Cocaine Selective Severity Assessment (CSSA) em mulheres usuárias de crack / Psychometric properties of Cocaine Selective Severity Assessment (CSSA) in crack users

Objetivo Este estudo teve como objetivo adaptar a Cocaine Selective Severity Assessment (CSSA) para o português do Brasil e verificar as propriedades psicométricas do instrumento em uma amostra de usuárias de crack. Métodos Após as etapas de tradução e adaptação, 125 mulheres usuárias de crack, internadas em uma unidade pública de desintoxicação, foram avaliadas. Para caracterização da amostra e análise das validades concorrente, de construto e preditiva, foram utilizados os seguintes instrumentos: SCID-I, ASI-6, BDI-II e CCQ-B. Resultados A análise fatorial exploratória identificou cinco fatores, com níveis adequados de consistência interna tanto para os fatores quanto para o escore geral da CSSA. Quanto à validade concorrente, a CSSA vai ao encontro de instrumentos já utilizados na clínica e em pesquisas. Em relação à validade de construto e preditiva, a CSSA pode ser sensível ao declínio dos sintomas de abstinência durante o processo de desintoxicação do crack. Conclusões Nossos achados foram além da tradução e adaptação da CSSA, proporcionando testes de validade e sugerindo que a CSSA é um instrumento confiável na avaliação dos sintomas de abstinência do crack. .

Objective This study aimed to describe the translation and adaptation of Cocaine Selective Severity Assessment (CSSA) into Brazilian Portuguese and verify the psychometric properties in a sample of crack cocaine users. Methods After the translation and adaptation steps, 125 female crack cocaine-dependent inpatients who were enrolled in an inpatient detoxification unit were evaluated. To characterize the sample and realize the analysis of concurrent validity, construct validity and predictive validity the following instruments were used: SCID-I, ASI-6, BDI-II e CCQ-B. Results The exploratory factorial analysis identified five factors and revealed appropriate levels of internal consistency, as well as the total score of the CSSA. The concurrent validity showed that CSSA was in line with instruments used in clinical practice and in researches. Further, both construct and predictive validity indicated adequate sensitivity to decline of withdrawal symptoms during the detoxification processes. Conclusions Our findings were beyond the translation and adaptation, providing the reliability and validity of CSSA regarding the evaluation of withdrawal symptoms in crack cocaine abstinence. .
