This study examines the impact of Attention Deficit/Hyperactivity Disorder (AD/HD) on college age students 18-25 years old. Qualitative research methods, including semi-structured interviews with students and significant others, writing samples and transcript documents, examine functional impairments of students with AD/HD as well as functional impairment impact on relationships, academics and work. This qualitative research, grounded theory, provides a model for future research studies confirming existing theory and provides a basis for new theory. The conclusion was that functional impairments continue to exist in college age adults with impairments with issues in concentration, organization, time related issues, time management/scheduling and hyperactivity. These in addition to issues with communication impact relationships with family and academic authority figures and significant other relationships as well as academic performance. The research provides knowledge that contributes to planning for community agency services and academic interventions to ensure the success of students in higher education and future careers.
