Effectively and efficiently identifying alcohol use disorder (AUD) is an essential goal for researchers and clinicians alike. To date, there are a limited number of self-reported tools specifically designed for evaluating DSM-5 criteria for AUD. The Brief DSM-5 AUD Diagnostic Assessment is a recently created participant self-reported measure with demonstrated reliability and validity in college student populations. The purpose of this study was to replicate and extend these findings by evaluating the psychometric properties of the Brief DSM-5 AUD Diagnostic Assessment in a geographically diverse adult sample with varying alcohol use history. Participants (N = 1986) were sampled from the crowdsourcing website Amazon Mechanical Turk (mTurk). The Brief DSM-5 AUD Diagnostic Assessment was completed to evaluate scale reliability and validity. A subset of individuals with answers indicative of AUD (N = 448) also completed a battery of standardized alcohol use questionnaires for additional validity assessments. High internal consistency reliability was observed (α = 0.92) along with strong item-total correlations. Convergent validity was supported by significant positive relationships between diagnostic category and measures of alcohol use consumption and severity. Modest relationships that were generally not statistically significant were observed with soda use measures supporting discriminant validity. AUD severity remained a significant predictor of alcohol use measures after accounting for AUDIT scores, thereby establishing incremental validity. These findings collectively support the Brief DSM-5 AUD Diagnostic Assessment as a reliable, valid, and rapid self-report tool for evaluating DSM-5 AUD in diverse research and clinical settings.
有效且高效地识别酒精使用障碍（AUD）是研究人员和临床医生的共同目标。迄今为止，仅有数量有限的自我报告工具是专门为评估 AUD 的 DSM-5 标准而设计的。《DSM-5 AUD 简短诊断评估》是一种最近创建的、参与者自我报告的工具，在大学生群体中已被证明具有可靠性和有效性。本研究的目的是通过在具有不同酒精使用史的地理上多样化的成年样本中评估《DSM-5 AUD 简短诊断评估》的心理测量特性，复制和扩展这些发现。参与者（N=1986）从众包网站 Amazon Mechanical Turk（mTurk）中抽取。完成《DSM-5 AUD 简短诊断评估》以评估量表的可靠性和有效性。一小部分回答表明存在 AUD 的个体（N=448）还完成了一系列标准化的酒精使用问卷，以进行额外的有效性评估。观察到高内部一致性可靠性（α=0.92）以及强烈的项目-总分相关性。诊断类别与酒精使用量和严重程度的测量值之间存在显著的正相关关系，支持了收敛有效性。观察到与苏打水使用测量值的适度关系，但通常不具有统计学意义，支持了区分有效性。在考虑 AUDIT 评分后，AUD 严重程度仍然是酒精使用测量值的显著预测因素，从而确立了增量有效性。这些发现共同支持《DSM-5 AUD 简短诊断评估》作为一种可靠、有效和快速的自我报告工具，可用于评估不同研究和临床环境中的 DSM-5 AUD。
