To perform criterion validation of the Key Question in Portuguese for screening at-risk alcohol use among users of Primary Healthcare services.
This is a psychometric study conducted with users of a Primary Healthcare service located in the city of São Paulo, Brazil. Participants responded to the Key Question which was applied in conjunction with the Alcohol Use Disorders Identification Test-C for concurrent validation and measurement of psychometric properties.
The sample consisted of 518 users. The Key Question presented 59% specificity and 99% sensitivity with respect to the Alcohol Use Disorders Identification Test-C in the general population. The accuracy was 81% in relation to this instrument. There was no influence of sociodemographic variables such as gender on the psychometric properties of the Key Question.
The results indicate that the Key Question in Portuguese presented satisfactory psychometric qualities and suggest that its Portuguese version is as efficient for screening at-risk alcohol use as its reference standard, which subsidizes its use in Primary Healthcare.
对葡萄牙语版关键问题进行标准效度验证，以筛查初级医疗服务使用者中存在酒精使用风险的情况。
这是一项针对巴西圣保罗市一家初级医疗服务机构使用者开展的心理测量学研究。参与者回答了关键问题，该问题与酒精使用障碍识别测试-C同时应用，用于并行效度验证和心理测量学特性测量。
样本包括518名使用者。在一般人群中，与酒精使用障碍识别测试-C相比，关键问题的特异性为59%，敏感性为99%。相对于该工具，准确率为81%。性别等社会人口统计学变量对关键问题的心理测量学特性没有影响。
结果表明，葡萄牙语版关键问题具有令人满意的心理测量学质量，其葡萄牙语版本在筛查酒精使用风险方面与参考标准一样有效，这为其在初级医疗保健中的应用提供了支持。
