The authors present a psychometric study of the questionnaire proposed by the Gamblers Anonymous organization for the self-assessment of problem gambling. The study was carried out in Spain with two samples: one of 127 problem gamblers (mean age: 41.67; sex: 78.7% men; mean duration of the problem: 5 years) and the other of 142 social gamblers (mean age: 38.46; sex: 60% men). The questionnaire was self-applied, in the presence of one of the investigators in case any doubts arose. The results indicate that it is a good screening instrument, with high reliability (Cronbach's alpha = 0.94), good covergent validity (the correlation with the SOGS questionnaire is high (r = 0.94; p < 0.001)), good factorial validity (the questionnaire's structure is unidimensional and coherent (just one factor explains more than 50% of the variance)), and its discriminative power is high (diagnostic efficacy = 98.88%). The study offers a comparative analysis of this instrument with other measures of problem gambling, emphasizing its extraordinary performance.
作者介绍了匿名戒赌者组织提出的用于问题赌博自我评估的问卷的心理测量学研究。该研究在西班牙进行，有两个样本：一个样本是127名问题赌徒（平均年龄：41.67岁；性别：78.7%为男性；问题平均持续时间：5年），另一个样本是142名社会赌徒（平均年龄：38.46岁；性别：60%为男性）。问卷由被调查者自行填写，如有任何疑问可在一名调查人员在场的情况下进行。结果表明，它是一种很好的筛查工具，具有高信度（克朗巴哈系数α = 0.94）、良好的收敛效度（与SOGS问卷的相关性很高（r = 0.94；p < 0.001））、良好的因子效度（问卷结构是单维且连贯的（仅一个因子解释了超过50%的方差）），并且其鉴别力很高（诊断效能 = 98.88%）。该研究对该工具与其他问题赌博测量方法进行了比较分析，强调了其卓越的表现。
