Abstract

Background and aims: There is growing evidence regarding the overlap between trading behaviors and gambling. However, problematic trading behaviors are often assessed using gambling-related instruments, which may not fully capture the nuances of trading. The present study developed and evaluated the psychometric properties of the Trading Disorder Scale (TDS), grounded in in the research criteria proposed by Guglielmo et al. (2016), based on DSM-5 criteria for gambling disorder and internet gaming disorder.

Methods: A cross-sectional survey was administered to 403 Spanish amateur traders. The TDS was tested for reliability, validity, and factorial structure. Latent class analysis (LCA) was used to identify patterns of disordered trading.

Results: EFA and CFA supported a one-factor solution for the TDS, which showed strong internal consistency (ωu-cat = 0.938, KR-20 = 0.877). The scale showed good concurrent validity with PGSI (r = 0.559) and good convergent validity with trading-related variables. LCA identified three classes: non-disordered trading (72.2%), at-risk trading (17.6%), and disordered trading (10.2%). Individuals in the disordered trading group scored higher on TDS, traded more frequently, monitored markets more intensively, and exhibited higher rates of problem gambling (PGSI≥5), impulsivity, and substance use. Guglielmo's cut-off point (≥5 criteria) effectively differentiated individuals with disordered trading behaviors from those at-risk and those without disordered trading.

Conclusions: The TDS is a reliable and valid instrument for assessing disordered trading among amateur investors. Further research is needed to explore the scale's predictive validity.

交易障碍量表用于评估问题交易行为的开发与验证。

背景和目的：越来越多的证据表明，交易行为和赌博之间存在重叠。然而，有问题的交易行为通常是用与赌博有关的工具来评估的，这可能无法完全捕捉到交易的细微差别。本研究基于Guglielmo等人（2016）基于DSM-5赌博障碍和网络游戏障碍标准提出的研究标准，开发并评估了交易障碍量表（TDS）的心理测量特性。方法：对403名西班牙业余交易者进行横断面调查。对TDS进行信度、效度和析因结构检验。使用潜类分析（LCA）来识别无序交易模式。结果：EFA和CFA支持TDS的单因素解决方案，具有较强的内部一致性（ωu-cat = 0.938, KR-20 = 0.877）。量表与PGSI具有良好的并发效度（r = 0.559），与交易相关变量具有良好的收敛效度。LCA确定了三个类别：非无序交易（72.2%）、风险交易（17.6%）和无序交易（10.2%）。交易紊乱组的个体在TDS上得分更高，交易更频繁，更密集地监控市场，并表现出更高的问题赌博（PGSI≥5），冲动和物质使用率。Guglielmo的截止点（≥5个标准）有效地区分了有交易障碍行为的个体、有风险的个体和无交易障碍的个体。结论：TDS是一种可靠、有效的评估业余投资者无序交易的工具。该量表的预测效度有待进一步研究。

期刊介绍： The aim of Journal of Behavioral Addictions is to create a forum for the scientific information exchange with regard to behavioral addictions. The journal is a broad focused interdisciplinary one that publishes manuscripts on different approaches of non-substance addictions, research reports focusing on the addictive patterns of various behaviors, especially disorders of the impulsive-compulsive spectrum, and also publishes reviews in these topics. Coverage ranges from genetic and neurobiological research through psychological and clinical psychiatric approaches to epidemiological, sociological and anthropological aspects.
