Do stimulants improve functioning in adults with ADHD?: A review of the literature

ADHD is prevalent in adulthood and stimulant pharmacotherapy is the primary treatment for uncomplicated presentations. ADHD is associated with significant functional impairment in major life roles. Measurement of the efficacy of stimulant treatment for adult ADHD therefore should include assessment of improvement in role function. A literature search was conducted to identify studies that measured change in function with stimulant treatment in adult ADHD using measures other than global clinical impression or global assessment of function ratings. Five studies were identified that met our search criteria. Evidence of functional improvement with stimulant treatment was found with the following validated self-report measures of functional wellbeing employed across these studies: the Medical Outcome Study 36-item Short Form Health Survey; ADHD Impact Module for Adults; Quality of Life Enjoyment and Satisfaction scale—Short Form; Sheehan Disability Scale, and Social Adjustment Scale—Self-Report. We conclude that investigations using self-report scales provide evidence that stimulant treatment translates into measurable improvement in daily function for adults with ADHD. Further investigation could better characterize the mediators and moderators of individual improvement, an important step towards the personalization of treatment for ADHD in adulthood.
