Objective:To expand on current adult ADHD literature by investigating the stability of ADHD symptomatology (i.e., inattention and hyperactivity-impulsivity) across a 15-year period (from emerging adulthood to early middle adulthood) and the relative contributions of ADHD symptomatology to life success.Method:A sample of 320 post-secondary students was initially assessed for ADHD symptomatology using the Conners’ Adult ADHD Rating Scale (CAARS). Fifteen years later, participants were re-assessed using the CAARS and several measures of life success (e.g., relationship satisfaction, career satisfaction, and stress levels).Results:Inattention and hyperactivity-impulsivity symptoms showed strong stability across the 15-year period. Additionally, inattention symptoms during emerging adulthood and early middle adulthood were consistently associated with poorer life success (i.e., lower relationship and career satisfaction), particularly for men. Associations for hyperactivity-impulsivity symptoms were less consistent.Conclusion:ADHD symptomatology can be conceptualized as a stable, dimensional trait across adulthood, with important impacts on life success.

ADHD 症状与人生成功之间的纵向关联：从成年初期到中年早期

目的：通过调查 15 年期间（从成年初期到成年早期）ADHD 症状（即注意力不集中和多动-冲动）的稳定性以及 ADHD 症状对人生成功的相对贡献，扩展当前成人 ADHD 文献。方法：使用康纳斯成人 ADHD 评定量表 (CAARS) 对 320 名专上学生样本进行 ADHD 症状初步评估。十五年后，使用 CAARS 和多项生活成功指标（例如，关系满意度、职业满意度和压力水平）对参与者进行了重新评估。结果：注意力不集中和多动冲动症状在 15 年期间表现出很强的稳定性。此外，成年初期和中年早期的注意力不集中症状始终与较差的生活成功率（即较低的人际关系和职业满意度）相关，特别是对于男性而言。多动-冲动症状之间的关联不太一致。结论：ADHD 症状可以被概念化为整个成年期的稳定的维度特征，对人生成功具有重要影响。
