Objective: To better understand current issues with adult ADHD assessment contributing to adult ADHD being under recognized and undertreated. Method: This study examined the relationship between symptoms, impairment, and executive functioning (EF) in a college sample. Results: Among individuals screening negative for ADHD, those higher in EF experienced significantly less impairment than those lower in EF. Executive functioning was shown to have a negative relationship with impairment while ADHD symptomology was shown to have a positive relationship with impairment. In addition, impairment was significantly predicted by ADHD symptom level and EF, and there was a significant interaction between EF and ADHD symptom level in predicting impairment. However, high EF did not significantly protect against impairment in individuals reporting a significant level of ADHD symptoms. Conclusion: Further research is needed to clarify the relationships between these variables in emerging adult college students.
