Since stress is known to play a role in the development of physical and mental illness, empirically validated measurements are required to assess the effect of adverse events such as the COVID-19 pandemic. The purpose of this study was to develop and evaluate the psychometric properties of the Adversity and Stress Scale (ASS). A sample of 3937 adults living in Mexico was used. The structure of the instrument was evaluated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Construct validity was measured through associations between the ASS and psychological symptoms. In the EFA, the relational and contextual dimensions of stress were identified. A good fit was obtained in the CFA (CFI = 0.980, RMSEA = 0.040). The ASS score was associated with all the selected variables in the expected direction, and internal consistency was α = .86. The ASS is a valid, reliable measure, with the potential to be used in other adverse events.
由于压力在身心疾病的发展中起着一定作用，因此需要经过实证验证的测量方法来评估诸如新冠疫情等不良事件的影响。本研究的目的是开发并评估逆境与压力量表（ASS）的心理测量特性。研究使用了居住在墨西哥的3937名成年人作为样本。通过探索性因素分析（EFA）和验证性因素分析（CFA）对该量表的结构进行了评估。通过ASS与心理症状之间的关联来衡量结构效度。在探索性因素分析中，确定了压力的关系维度和情境维度。在验证性因素分析中获得了良好的拟合度（CFI = 0.980，RMSEA = 0.040）。ASS得分与所有选定变量在预期方向上相关，内部一致性为α = 0.86。ASS是一种有效、可靠的测量工具，有可能用于其他不良事件。
