The dynamics between self-regulation problems and ADHD, MDD, and GAD may reveal insights into the co-occurrence of the three disorders. The present study focused on psychological factors that support or threaten successful self-regulation. Using cross-sectional data, a network analysis was performed based on a sample of 902 students currently enrolled in higher education programs in the Netherlands. The analysis featured 17 commonly studied risk and protective factors associated with all three disorders. The network showed that irritability and impairments in daily functioning were shared problems between ADHD, MDD, and GAD. The network further suggested that impaired cognition and a propensity for procrastination are shared features of ADHD and MDD. ADHD and GAD did not share a direct relationship, diverging from previous assumptions. The findings highlight that the relationship between the disorders may depend on shared vulnerabilities and outcomes that act as bridges in the network. The study illustrates that psychological constructs need to be more clearly defined to move forward when researching co-morbidity beyond the level of symptoms.Show less
