Abstract

Objective: To evaluate stimulant medication on symptoms and functioning for college students with ADHD using double-blind, placebo-controlled, crossover design. Method: Participants included 24 college students with ADHD and 26 college students without psychopathology. Lisdexamfetamine dimesylate (LDX) was examined for ADHD participants over five weekly phases (no-drug baseline, placebo, 30-, 50-, and 70-mg LDX per day). Self-report rating scales of functioning and direct assessment of ADHD symptoms, verbal learning/memory, and adverse side effects were collected (baseline only for control students). Results: LDX was associated with large reductions in ADHD symptoms and improvement in executive functioning along with smaller effects for psychosocial functioning. Reduction in ADHD symptoms was found for 86.4% of participants; however, large differences in symptoms and executive functioning remained relative to controls. Conclusion: LDX is a safe, efficacious treatment for symptom relief in college students with ADHD. Research documenting medication effects on academic functioning and evaluating psychosocial/educational interventions is needed.

  • Other studies have observed self-reported EF changes resulting from stimulant medication use among college students with ADHD.

    “Although no studies have used the BDEFS-SF-M, other studies (e.g., DuPaul et al., 2012) have observed self-reported EF changes resulting from stimulant medication use among college students with ADHD.”
  • Specific aspects of executive functioning improved with LDX were BRI, MCI, GEC, including inhibition, initiation, working memory, planning and organizing, task management, and organization of materials.

    “Specific aspects of executive functioning, which improved with LDX, were noted for BRI, MCI, GEC, including inhibition, initiation, working memory, planning and organizing, task management, and organization of materials.”
  • In a double-blind, placebo-controlled crossover study in college students with ADHD, LDX relative to no medication baseline and placebo was associated with significant reductions in ADHD symptoms (CAARS) and improvement in executive functioning for nearly all BRIEF-A subscales (both P < .001), with similar effects for psychosocial functioning (SCL-90-R) (P < .02).

    “LDX relative to no medication baseline and placebo was associated with significant reductions in ADHD symptoms as assessed via Conners’ Adult ADHD Rating Scales (CAARS) and improvement in executive functioning for nearly all BRIEF-A subscales (both, P < .001), with similar effects for psychosocial functioning, using the Symptom Checklist 90-Revised (SCL-90-R) (P < .02).”
  • In a double-blind, placebo-controlled trial in young adults with ADHD, compared with placebo, posttreatment with LDX improved reaction time across 5 surprise events, significantly reduced accidents, produced significantly faster reaction times (91% faster), and lower rate of simulated driving collisions.

    “Compared with placebo, posttreatment with LDX revealed positive effect on reaction time across 5 surprise events and significantly fewer accidents.”
  • LDX compared with placebo from baseline to study end point was associated with small but significant increases in pulse (mean change: 15.8, P < .001) and QTc interval (mean change: 9.7, P = .01), although no serious adverse events were reported.

    “Likewise, LDX compared with placebo from baseline to study end point was associated with small but significant increases in pulse (mean change: 15.8, P < .001) and QTc interval (corrected QT interval) (mean change: 9.7, P = .01), although no serious adverse events were reported during the study period.31”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
