The trait-impulsivity hypothesis posits impulsivity as the underlying substrate of Attention-deficit/hyperactivity disorder (ADHD) and Oppositional defiant disorder (ODD) symptom expressions. The current study applied network analysis to evaluate the inter-relationships of dimensions within ADHD (inattention and hyperactivity/impulsivity) and ODD (anger/irritable, vindictiveness, and argumentative/defiant behavior) with components of impulsivity as captured by the UPPS-P model (negative urgency, lack of premeditation, lack of perseverance, sensation seeking, and positive urgency).
A total of 324 emerging adults (women = 246) from the general community completed questionnaires covering these dimensions.
Our findings showed that the ADHD and ODD dimensions were associated differentially with different types of impulsivity, in their unique patterns of network connectivities, a possibility that has had little attention in the trait-impulsivity hypothesis literature.
This study is the first to tease out the unique associations of the ADHD and ODD dimensions with different types of impulsivity, and in that way provide new contributions to our understanding of the existing trait impulsivity theory. Our findings would be especially relevant to those interested in understanding how different dimensions of trait impulsivity underly the ADHD and ODD dimensions.
特质冲动性假说认为冲动性是注意力缺陷多动障碍（ADHD）和对立违抗障碍（ODD）症状表现的潜在基础。当前研究应用网络分析来评估ADHD（注意力不集中和多动/冲动）和ODD（愤怒/易激惹、报复心、爱争论/挑衅行为）维度与UPPS-P模型所捕捉的冲动性成分（消极紧迫感、缺乏预谋、缺乏毅力、寻求刺激和积极紧迫感）之间的相互关系。
来自普通社区的324名新兴成年人（女性 = 246名）完成了涵盖这些维度的问卷调查。
我们的研究结果表明，ADHD和ODD维度在其独特的网络连接模式中与不同类型的冲动性存在差异关联，这一可能性在特质冲动性假说文献中很少受到关注。
本研究首次梳理出ADHD和ODD维度与不同类型冲动性之间的独特关联，从而为我们理解现有特质冲动性理论提供了新的贡献。我们的研究结果对于那些有兴趣了解特质冲动性的不同维度如何构成ADHD和ODD维度基础的人来说尤其相关。
