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 ( = 968, = 29.5 years, = 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.
赌博障碍行为，如某人对赌博的过度关注和/或因赌博导致的情绪改变，其诊断权重/重要性被认为存在差异，尤其是在为诊断量表提供信息时。为提高评估准确性，必须考虑这种潜在差异。鉴于在线提供的赌博机会迅速增加，后者尤为重要。为推动这一知识领域的发展，本研究评估了一个在线成人社区样本（n = 968，M = 29.5岁，SD = 9.36岁）对在线赌博障碍问卷（OGD-Q）的回答。项目反应理论（IRT）程序在项目和量表层面检验了该工具的心理测量特性。结果表明，OGD-Q显示出可靠评估问题赌博以及区分处于类似特质水平个体的良好能力，尤其是在高于均值1至3个标准差之间。研究结果还表明，OGD-Q的各组成部分/项目具有不同的区分能力，而且在不同程度赌博障碍行为的受访者中，其信度也存在差异。因此，支持在评估过程中考虑个体项目反应的差异权重，同时考虑其赌博障碍行为的严重程度。
