The South Oaks Gambling Screen–Revised Adolescent (SOGS-RA) is one of the most widely used screening tools for problem gambling among adolescents. In this study, item response theory was used for computing measures of problem gambling severity that took into account how much information the endorsed items provided about the presence of problem gambling. A zero-inflated mixture two-parameter logistic model was estimated on the responses of 4,404 adolescents to the South Oaks Gambling Screen–Revised Adolescent to compute the difficulty and discrimination of each item, and the problem gambling severity level (θ score) of each respondent. Receiver operating characteristic curve analysis was used to identify the cutoff on the θ scores that best distinguished daily and nondaily gamblers. This cutoff outperformed the common cutoff defined on the sum scores in identifying daily gamblers but fell behind it in identifying nondaily gamblers. When screening adolescents to be subjected to further investigations, the cutoff on the θ scores must be preferred to that on the sum scores.

南橡树赌博筛查 - 修订版青少年 (SOGS-RA) 是青少年赌博问题最广泛使用的筛查工具之一。在这项研究中，项目反应理论用于计算问题赌博严重程度的衡量标准，该衡量标准考虑了被认可的项目提供了多少关于问题赌博存在的信息。对 4,404 名青少年对 South Oaks Gambling Screen-Revised Adolescent 的反应进行了零膨胀混合双参数逻辑模型估计，以计算每个项目的难度和辨别力，以及每个受访者的问题赌博严重程度（θ 分数） . 接受者操作特征曲线分析用于确定最能区分每日和非每日赌徒的 θ 分数的截止值。在识别日常赌徒时，该截止值优于根据总分定义的常见截止值，但在识别非日常赌徒时却落后于它。在筛选青少年以进行进一步调查时，必须优先考虑 θ 分数的截止值而不是总分的截止值。
