在之前的一篇论文中，我们在一项大型双胞胎研究中证明了DSM-IV症状集定义的赌博障碍（DG）在家庭中运行，大约一半的DG责任变化是由于家庭因素，所有这些都是由共同的遗传而不是共同的环境影响所解释的。本研究的目的是扩展这项工作，也包括另一种概念化的DG，这是由南橡树赌博屏幕（SOGS）的项目集，以（a）比较的幅度获得的家族相似性时，使用两个定义的DG（基于DSM-IV和SOGS），（B）检查这两个定义在多大程度上利用了遗传和环境变异的相同潜在来源，以及（c）研究在男性和女性中是否会获得相同的结果。双变量双模型拟合分析的结果表明，DG定义的DSM-IV和SOGS基本上重叠在男性和女性之间的病因水平，这支持了结构效度的DSM和SOGS概念化的DG。这项研究强调了双胞胎研究的效用，用于评估诊断命名法的有效性。
In a previous paper we demonstrated in a large twin study that disordered gambling (DG) as defined by the DSM-IV symptom set runs in families, that about half of the variation in liability for DG was due to familial factors, and that all of this was explained by shared genetic rather than shared environmental influences. The purpose of the present study was to extend this work to also include an alternative conceptualization of DG that is provided by the South Oaks Gambling Screen (SOGS) item set in order to (a) compare the magnitude of the familial resemblance obtained when using the two definitions of DG (based on the DSM-IV and the SOGS), (b) examine the extent to which the two definitions tap the same underlying sources of genetic and environmental variation, and (c) examine whether the same results will be obtained among men and women. The results of bivariate twin model-fitting analyses suggested that DG as defined by the DSM-IV and SOGS substantially overlapped at the etiologic level among both men and women, which supports the construct validity of both the DSM and SOGS conceptualizations of DG. This study highlights the utility of twin studies for appraising the validity of the diagnostic nomenclature.
