Abstract

Gambling disorder behaviours, such as one’s preoccupation with gambling and/or mood modification due to gambling, have been proposed to differ in their diagnostic weight/importance, especially when informing diagnostic scales. Such potential differences are imperative to be considered to improve assessment accuracy. The latter is particularly important in the light of the rapidly increasing gambling opportunities offered online. To contribute to this area of knowledge, the current study assessed an online adult community sample (N = 968, M_age = 29.5 years, SD_age = 9.36 years) regarding their responses on the Online Gambling Disorder Questionnaire (OGD-Q). Item response theory (IRT) procedures examined the psychometric properties of the instrument, at both the item and the scale level. Results indicated that the OGD-Q demonstrated good capacity to reliably assess problem gambling and differentiate between individuals at similar levels of the trait, particularly between 1 and 3 SDs above the mean. The findings also showed OGD-Q components/items possess varying discrimination capacities, whilst they also differ in reliability across respondents with different levels of disordered gambling behaviours. Thus, it is supported that consideration is required regarding the differential weighting of one’s item responses in the assessment procedure, taking concurrently into account their severity of disordered gambling behaviours.

网络赌博障碍问卷(OGD-Q):项目反应理论检验

赌博障碍行为，如一个人对赌博的专注和/或因赌博而引起的情绪改变，被认为在诊断权重/重要性上有所不同，特别是在告知诊断量表时。为了提高评估的准确性，必须考虑这些潜在的差异。鉴于网上提供的赌博机会迅速增加，后者尤其重要。为了对这一领域的知识有所贡献，目前的研究评估了一个在线成人社区样本(N = 968，年龄= 29.5，年龄= 9.36)关于他们对在线赌博障碍问卷(OGD-Q)的反应。项目反应理论(IRT)程序在项目和量表水平上检查了该工具的心理测量特性。结果表明，OGD-Q在评估问题赌博和区分具有相似特征水平的个体方面表现出良好的能力，特别是在高于平均值的1和3个标准差之间。研究结果还显示，OGD-Q成分/项目具有不同的辨别能力，同时它们在不同程度的赌博行为紊乱的受访者中也存在可靠性差异。因此，需要考虑在评估程序中对一个人的项目反应的不同权重，同时考虑到他们的赌博行为紊乱的严重程度。

期刊介绍： Addictive Behaviors Reports is an open-access and peer reviewed online-only journal offering an interdisciplinary forum for the publication of research in addictive behaviors. The journal accepts submissions that are scientifically sound on all forms of addictive behavior (alcohol, drugs, gambling, Internet, nicotine and technology) with a primary focus on behavioral and psychosocial research. The emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. We are particularly interested in ''non-traditional'', innovative and empirically oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research. Studies that might encourage new lines of inquiry as well as scholarly commentaries on topical issues, systematic reviews, and mini reviews are also very much encouraged. We also welcome multimedia submissions that incorporate video or audio components to better display methodology or findings.
