问题赌博严重程度指数（PGSI）是一个广泛使用的九项量表，用于测量一般人群中赌博问题的严重程度。在PGSI定义的四种赌徒类型中，无问题，低风险，中等风险和问题赌徒，只有后一类在量表的开发过程中进行了有效性测试，尽管超过95%的赌徒属于其余三类之一。使用加拿大人口数据超过25,000赌徒，我们进行了全面的有效性和可靠性分析的四个PGSI赌徒类型。PGSI亚型在14个月间隔内的时间稳定性适中，但足够（组内相关系数= 0.63）。有强有力的证据的有效性的非问题和问题赌徒类别，但低风险和中等风险类别显示差的判别效度使用现有的评分规则。通过对评分系统进行简单的修改，这些类别的有效性得到了提高。
The Problem Gambling Severity Index (PGSI) is a widely used nine item scale for measuring the severity of gambling problems in the general population. Of the four gambler types defined by the PGSI, non-problem, low-risk, moderate-risk and problem gamblers, only the latter category underwent any validity testing during the scale's development, despite the fact that over 95% of gamblers fall into one of the remaining three categories. Using Canadian population data on over 25,000 gamblers, we conducted a comprehensive validity and reliability analysis of the four PGSI gambler types. The temporal stability of PGSI subtype over a 14-month interval was modest but adequate (intraclass correlation coefficient = 0.63). There was strong evidence for the validity of the non-problem and problem gambler categories however the low-risk and moderate-risk categories showed poor discriminant validity using the existing scoring rules. The validity of these categories was improved with a simple modification to the scoring system.
