Objective: We sought to elucidate the effects of an organization, time management, and planning (OTMP) skills training intervention for college students reporting elevated levels of ADHD symptomatology and academic impairment. Method: Undergraduate participants enrolled in either the intervention (n = 22) or comparison (n = 15) condition in exchange for psychology course credit. Those in the intervention condition attended three weekly group meetings designed to improve organizational skills. Treatment effectiveness was evaluated by comparing pre- and postmeasurements of academic impairment, inattention, hyperactivity/impulsivity, and OTMP skills utilization. Results: Intervention group participants improved significantly on ratings of inattention, hyperactivity/impulsivity, and academic impairment, relative to the comparison group. Intervention group participants also improved in their use of OTMP skills, relative to their baseline ratings. Conclusion: This study suggests an organizational skills intervention has the potential to ameliorating ADHD symptomatology and academic impairment among college students.
