Abstract

ABSTRACT The nine-item Problem Gambling Severity Index (PGSI) is a self-report measure of problem gambling severity used in empirical and prevalence studies. This study examined the psychometric properties of the PGSI among older adult samples (60+ years), which have not yet been evaluated in the literature. Age equivalence of measures originally developed for use among general adult samples cannot be assumed; thus, such instruments should be evaluated to ensure appropriate use of such measures. Data were derived from the Leisure, Lifestyle, and Lifecycle Project and Quinte Longitudinal Study. Results of exploratory and confirmatory factor analyses supported a single-factor structure. Factor invariance between genders was identified. Internal consistency was considered good for the overall sample (α = .86). Concurrent validity between monthly overall gambling frequency and game types (EGMs, bingo, and instant win tickets) were supported for both continuous PGSI total score and categorical PGSI. In sum, the PGSI total score accurately reflects the construct of problem gambling among older adults.

老年人问题赌博严重程度指数的心理测量特征

九项问题赌博严重程度指数(PGSI)是在实证和流行研究中使用的问题赌博严重程度的自我报告措施。本研究考察了老年人样本(60岁以上)PGSI的心理测量特性，这在文献中尚未得到评估。不能假设最初用于一般成人样本的测量方法的年龄等效;因此，应评价这些文书，以确保适当使用这些措施。数据来源于休闲、生活方式和生命周期项目和昆特纵向研究。探索性和验证性因素分析的结果支持单因素结构。确定了性别间的因素不变性。整体样品的内部一致性被认为是良好的(α = .86)。连续PGSI总分和分类PGSI均支持每月总体赌博频率和游戏类型(egm，宾果和即时中奖票)之间的并发效度。总之，PGSI总分准确地反映了老年人问题赌博的结构。
