The aim of this study was to examine low hedonic responsivity, a facet of hedonic capacity, as a potential explanatory variable in the relationship between attention deficit/hyperactivity disorder (ADHD) symptoms and depressive symptoms.
One hundred ninety-eight undergraduate students (mean age = 21.3, standard deviation = 4.6; 59.6% women) from a large, public university completed self-report measures for this cross-sectional study.
Results indicated that ADHD symptoms were significantly associated with depressive symptoms, and that low hedonic responsivity partially accounted for this association. This effect was statistically significant for total ADHD symptoms and inattentive symptoms, but not for hyperactive-impulsive symptoms.
Findings are consistent with the possibility that impaired hedonic responsiveness may be a common endophenotype for depression and the inattentive symptoms of ADHD. Implications for future research and clinical work are discussed.
本研究旨在探讨愉悦反应性低下(愉悦能力的一个方面)是否可以作为注意缺陷多动障碍(ADHD)症状与抑郁症状之间关系的一个潜在解释变量。
本横断面研究招募了来自一所大型公立大学的 198 名本科生(平均年龄=21.3,标准差=4.6;59.6%为女性),并让他们完成了自我报告式的测量。
结果表明,ADHD 症状与抑郁症状显著相关,而愉悦反应性低下部分解释了这种关联。这种关联在 ADHD 症状的总分和注意力不集中症状上具有统计学意义,但在多动冲动症状上不具有统计学意义。
这些发现与愉悦反应性低下可能是抑郁和 ADHD 的注意力不集中症状的共同内表型的可能性一致。讨论了对未来研究和临床工作的影响。
