The Gambling Attitudes and Beliefs Survey (GABS) is a questionnaire which explores gambling-related dysfunctional beliefs in an unidimensional way. The present research aims to investigate the dimensionality of the scale. 343 undergraduate student gamblers and 75 pathological gamblers seeking treatment completed the GABS and the south oaks gambling screen. Exploratory and confirmatory factor analyses revealed that the original one-factor structure of the GABS did not fit the data effectively. We then proposed a shorter version of the GABS (GABS-23) with a new five-factor structure, which fitted with the data more efficiently. The comparisons between students (problem vs. non-problem gamblers) and pathological gamblers seeking treatment indicated that the GABS-23 can discriminate between problem and non-problem gamblers as efficiently as the original GABS. To ensure the validity and the stability of the new structure of the GABS-23, analyses were replicated in an independent sample that consisted of 628 gamblers (256 non problem gamblers, 169 problem gamblers who are not treatment-seeking and 203 problem gamblers seeking treatment). Analyses showed satisfactory results, and the multidimensional structure of the GABS-23 was then confirmed. The GABS-23 seems to be a valid and useful assessment tool for screening gambling-related beliefs, emotions and attitudes among problem and non-problem gamblers. Moreover, it presents the advantage of being shorter than the original GABS, and of screening irrational beliefs and attitudes about gambling in a multidimensional way. The five-factor model of the GABS-23 is discussed based on the theory of locus of control.
赌博态度和信念调查（GABS）是一种问卷，它以单维的方式探索与赌博相关的功能失调信念。本研究旨在探讨该量表的维度结构。343 名大学生赌徒和 75 名寻求治疗的病态赌徒完成了 GABS 和南奥克斯赌博筛查。探索性和验证性因素分析表明，GABS 的原始单因素结构不能有效地拟合数据。我们随后提出了一个更短的 GABS 版本（GABS-23），具有新的五因素结构，更有效地拟合数据。学生（问题与非问题赌徒）和寻求治疗的病态赌徒之间的比较表明，GABS-23 可以像原始 GABS 一样有效地区分问题和非问题赌徒。为了确保 GABS-23 新结构的有效性和稳定性，在一个由 628 名赌徒（256 名非问题赌徒、169 名不寻求治疗的问题赌徒和 203 名寻求治疗的问题赌徒）组成的独立样本中进行了分析。分析结果令人满意，GABS-23 的多维结构得到了确认。GABS-23 似乎是一种有效的、有用的评估工具，可以筛选问题和非问题赌徒的与赌博相关的信念、情绪和态度。此外，它比原始 GABS 更短，并且能够以多维的方式筛选对赌博的非理性信念和态度。基于控制源理论，讨论了 GABS-23 的五因素模型。
