The purpose of this study was to examine the relationship between the chronological age of one's diagnosis and dysfunctional career thoughts among college students with Attention Deficit Hyperactivity Disorder. What is currently known about the timing of ADHD diagnosis and how it could potentially impact or have an effect on one's career thoughts as it pertains to making educational and career decisions is nonexistent. Given the increase of ADHD among college students, it was worth exploring the impact that age of one's diagnosis has on career thoughts.
