The Mental Impact and Distress Scale: COVID-19 (MIDc) was constructed and validated by one of the first pandemic-impact research teams in February 2020 and aims to assess psychosocial impacts of the COVID-19 pandemic. The purpose of the present research was to determine the psychometric properties of the MIDc's Brazilian form and outline a sociodemographic profile of the pandemic's psychosocial impact in a Brazilian sample. Altogether, 1004 Brazilians living in different regions of Brazil completed an online survey. The adapted Brazilian version presented significant validity and reliability as assessed by exploratory and confirmatory factor analysis, Cronbach alpha and Spearman-Brown coefficients, and associations with related psychological measures. Even though the Brazilian version differs from a previous (Macau) version, it contains both anticipation (i.e., the mental engagement processes of managing the unknowns) and modulation (i.e., the mental processes of insulation being activated to maintain a sense of normalcy) factors. Findings indicate greater vulnerability to modulation among younger and female participants. Black participants and those with lower family income were more prone to be economically impacted. Participants living in isolation were more vulnerable to anticipation. Thus, the COVID-19 pandemic was found to differentially affect gender, ethnic, and social groups in Brazil.

巴西 COVID-19 大流行的心理影响：心理影响和痛苦筛查工具的适应和验证以及影响的社会人口学特征

心理影响和痛苦量表：COVID-19 (MIDc) 由首批大流行影响研究团队之一于 2020 年 2 月构建和验证，旨在评估 COVID-19 大流行的心理社会影响。本研究的目的是确定 MIDc 巴西形式的心理测量特性，并概述大流行对巴西样本的心理社会影响的社会人口学概况。总共有 1004 名居住在巴西不同地区的巴西人完成了一项在线调查。通过探索性和验证性因素分析、Cronbach α 和 Spearman-Brown 系数以及与相关心理测量的关联评估，改编的巴西版本具有显着的有效性和可靠性。尽管巴西版本与之前的（澳门）版本不同，它包含预期（即管理未知事物的心理参与过程）和调节（即激活绝缘的心理过程以保持正常感）因素。研究结果表明，年轻和女性参与者更容易受到调制。黑人参与者和家庭收入较低的人更容易受到经济影响。与世隔绝的参与者更容易受到预期的影响。因此，发现 COVID-19 大流行对巴西的性别、种族和社会群体产生了不同的影响。研究结果表明，年轻和女性参与者更容易受到调制。黑人参与者和家庭收入较低的人更容易受到经济影响。与世隔绝的参与者更容易受到预期的影响。因此，发现 COVID-19 大流行对巴西的性别、种族和社会群体产生了不同的影响。研究结果表明，年轻和女性参与者更容易受到调制。黑人参与者和家庭收入较低的人更容易受到经济影响。与世隔绝的参与者更容易受到预期的影响。因此，发现 COVID-19 大流行对巴西的性别、种族和社会群体产生了不同的影响。
