To perform a construct validation of the List of Threatening Events Questionnaire (LTE-Q), as well as convergence validation by identifying its association with drug use in a sample of the Brazilian population.
This is a secondary analysis of the Second Brazilian National Alcohol and Drugs Survey (II BNADS), which used a cross-cultural adaptation of the LTE-Q in a probabilistic sample of 4,607 participants aged 14 years and older. Latent class analysis was used to validate the latent trait adversity (which considered the number of events from the list of 12 item in the LTE experienced by the respondent in the previous year) and logistic regression was performed to find its association with binge drinking and cocaine use.
The confirmatory factor analysis returned a chi-square of 108.341, weighted root mean square residual (WRMR) of 1.240, confirmatory fit indices (CFI) of 0.970, Tucker-Lewis index (TLI) of 0.962, and root mean square error approximation (RMSEA) score of 1.000. LTE-Q convergence validation showed that the adversity latent trait increased the chances of binge drinking by 1.31 time and doubled the chances of previous year cocaine use (adjusted by sociodemographic variables).
The use of the LTE-Q in Brazil should be encouraged in different research fields, including large epidemiological surveys, as it is also appropriate when time and budget are limited. The LTE-Q can be a useful tool in the development of targeted and more efficient prevention strategies.
对威胁事件问卷清单（LTE-Q）进行结构效度验证，并通过确定其与巴西人群样本中药物使用的关联进行收敛效度验证。
这是对第二次巴西全国酒精和药物调查（II BNADS）的二次分析，该调查在4607名14岁及以上参与者的概率样本中对LTE-Q进行了跨文化改编。使用潜在类别分析来验证潜在特质逆境（考虑受访者在前一年经历的LTE中12项清单中的事件数量），并进行逻辑回归以找出其与暴饮和可卡因使用的关联。
验证性因素分析得出卡方值为108.341，加权均方根残差（WRMR）为1.240，验证性拟合指数（CFI）为0.970，塔克-刘易斯指数（TLI）为0.962，均方根误差近似值（RMSEA）得分为1.000。LTE-Q收敛效度验证表明，逆境潜在特质使暴饮的几率增加了1.31倍，使前一年使用可卡因的几率增加了一倍（经社会人口统计学变量调整）。
应鼓励在巴西的不同研究领域使用LTE-Q，包括大型流行病学调查，因为在时间和预算有限时它也适用。LTE-Q可以成为制定有针对性和更有效预防策略的有用工具。
