ABSTRACT

Objective

The Iowa Gambling Task (IGT) and the Delay Discounting Test (DDT) are two of the most widely used decision-making tests within the field of addiction research. The IGT creates a context of uncertainty where immediate rewards or long-term benefits are chosen, whilst the DDT measures the change in value of a reward as the time taken to obtain it increases. The objective of this study was to analyze the psychometric properties of a new task: Deciding about your health (DAYH), which integrates both components.

Method

Longitudinal observational study. The sample was composed of 97 patients being treated for cocaine use disorder. The DAYH, IGT, DDT and other instruments for measuring dependence severity were administered. Relapse was evaluated within 3 and 6 months after the baseline assessment.

Results

Reliability was indicated by an intraclass correlation coefficient (r) of. 80. DAYH scores showed significant relationships with IGT (r = −.237; p <.05), although not with DDT (r =.048) scores. A relationship was also found between DAYH and dependency severity (r = −.213; p <.05) and craving (r = −.231; p <.05). The DAYH scores showed sensitivity to change, and the capacity to predict relapse.

Conclusions

These findings indicate the utility of DAYH for exploring decision-making in patients with substance use disorders. The relationships with IGT and DDT also indicate the need to further investigate how decisions are made in various contexts of choice.

药物滥用障碍患者的决策：可靠性，收敛效度和对新行为措施改变的敏感性

摘要

目的

爱荷华州赌博任务（IGT）和延迟折扣测试（DDT）是成瘾研究领域中使用最广泛的两个决策测试。IGT在选择即时奖励或长期利益的情况下创造了不确定性，而DDT则随着奖励时间的增加而衡量奖励价值的变化。这项研究的目的是分析一项新任务的心理测量特性：决定您的健康状况（DAYH），该任务综合了这两个方面。

方法

纵向观察研究。该样本由97位因可卡因使用障碍而接受治疗的患者组成。使用了DAYH，IGT，DDT和其他用于测量依赖性严重程度的仪器。在基线评估后3个月和6个月内评估复发率。

结果

可靠性由组内相关系数（r）表示。80. DAYH得分与IGT有显着相关性（r = −.237； p <.05），而与DDT得分则无显着关系（r = .048）。还发现DAYH与依赖严重性（r = -.213; p <.05）和渴望（r = -.231; p <.05）之间存在关系。DAYH得分显示出对变化的敏感性以及预测复发的能力。

结论

这些发现表明，DAYH可用于探索药物滥用障碍患者的决策。与IGT和DDT的关系还表明需要进一步研究如何在各种选择的环境中做出决策。
