The potential for abuse is another problem associated with stimulant use in the college population. Beyond what is known about psychostimulants, little research has been done to develop effective, non-pharmacological interventions for young adults with ADHD. Behavior Therapy has been shown to be one promising adjunctive treatment to central nervous system medication. An emerging adjunctive treatment in health psychology is the use of smartphone applications to manage symptoms and/or increase compliance. At the beginning of 2012, the amount of smartphones in use equaled feature phones and the amount of applications available for download succeeds 500,000. Now more than ever, treatment intervention delivered via smartphone application is a possibility. While past research has focused on the treatment of ADHD through the use of psycho-stimulants and behavioral interventions, this research evaluated the treatment efficacy of a time/goal management smartphone application grounded in evidence-based behavioral therapy.
