Impulsivity symptoms have been studied thoroughly in adults with ADHD, including hasty actions and decisions without considering possible consequences. The objective of our study was to investigate impulsive buying and deferment of gratification among adults with ADHD and a comparison group.
The participants were 225 adults with ADHD and 121 university students who completed the Buying Impulsiveness Scale (BIS), the Deferment of Gratification Questionnaire (DOGQ), the Adult ADHD Rating Scale-IV (ADHD-RS), as well as background questions.
Significant differences were found between the two groups on the three scales, the ADHD group showing more ADHD symptoms, more frequent impulsive buying behaviour and less ability to defer gratification. Mediation analyses yielded significant indirect effects in both samples, which suggests that the relationship between ADHD symptoms and impulsive buying is mediated by the ability to defer gratification.
The results suggest that placing emphasis on improving the capacity of adults with ADHD to defer gratification might be beneficial in treatment.
冲动症状在患有注意力缺陷多动障碍（ADHD）的成年人中已得到充分研究，包括不考虑可能后果的仓促行动和决定。我们研究的目的是调查患有ADHD的成年人与对照组之间的冲动性购买和延迟满足情况。
参与者为225名患有ADHD的成年人和121名大学生，他们完成了购买冲动量表（BIS）、延迟满足问卷（DOGQ）、成人ADHD评定量表-IV（ADHD-RS）以及背景问题。
两组在这三个量表上存在显著差异，ADHD组表现出更多的ADHD症状、更频繁的冲动性购买行为以及更低的延迟满足能力。中介分析在两个样本中均产生了显著的间接效应，这表明ADHD症状与冲动性购买之间的关系是由延迟满足能力介导的。
结果表明，强调提高患有ADHD的成年人延迟满足的能力可能对治疗有益。
