Emotional dysregulation and health related quality of life in young adults with ADHD: a cross sectional study

Objective Attention Deficit Hyperactivity Disorder (ADHD) is associated with emotional dysregulation (ED) and impaired health related quality of life (HRQoL). However, the role of ED in explaining the relationship between ADHD and HRQoL is unclear. The purpose of the present study was to do so in a sample of non-referred young adults with and without ADHD. Method The study design was cross-sectional. A non-clinical sample of 63 young adults with ADHD (mean age = 24.86 years, SD = 3.25, 78% university students) and 69 gender-matched controls (mean age = 23.84 years, SD = 2.59, 89% university students) were recruited. The Adult ADHD Quality-of-Life scale was used to measure HRQoL; The Self-Report Wender-Reimherr Adult Attention Deficit Disorder Scale and the Difficulties in Emotion Regulation Scale were used to measure ED. Group differences on all measures were tested using univariate and multivariate analyses of covariance, while controlling for age. Finally, a moderation analysis was used in order to examine the impact of ED on HRQoL beyond that accounted for by ADHD symptoms. Results Both HRQoL and ED were significantly worse for the ADHD group compared to the control group. The medication status of the ADHD group participants had no significant effect on the level of ADHD symptoms, ED or HRQoL. ED moderated the effect of ADHD symptoms on HRQoL for the ADHD group. Conclusion The findings support the centrality of ED in ADHD and its crucial influence on HRQoL. Young adults with ADHD and high levels of ED are at risk for aversive impact on their well-being regardless of their ADHD symptoms level. Plain English summary Young adults with Attention Deficit Hyperactivity Disorder (ADHD) struggle with poor quality of life (QoL). Emotional regulation is one's ability to modify their emotional state to promote adaptive, goal-oriented behaviors. Emotional dysregulation is a common yet neglected feature of people with ADHD. Our results show that young adults with ADHD are twice more likely to suffer from emotional dysregulation then their peers. Moreover, higher levels of emotional dysregulation predicted lower levels of QoL. These findings support the centrality of ED in ADHD and their crucial influence on everyday QoL. These findings are important not only on the theoretical level, but may also contribute to the design of interventions that aim to promote quality of life.
