Overview

Randomized trial demonstrates sustained reductions in inattention after group CBT in adults with ADHD, suggesting long-term durability supported by digital boosters.

Key Points

  • To assess the 8-year durability of group cognitive behavioral therapy (CBT) and examine the exploratory role of digital booster sessions for adults with ADHD.
  • Forty-eight adults from outpatient clinics across Japan (mean age = 39, 87% female) were randomized to group CBT or treatment-as-usual (TAU), with an optional digital booster offered to CBT participants at 5 years.
  • Follow-up assessments occurred at 8 years evaluating the primary outcome (CAARS Inattention/Memory) and secondary functional outcomes using intention-to-treat linear mixed models and multiple imputation sensitivity analyses.
  • At the 8-year follow-up (n=24 completers, 50% attrition), CBT showed lower inattention relative to TAU (p = .038, d = -0.65), though this did not survive multiple imputation.
  • Improvements in DSM inattentive symptoms (p = .025, ηp² = .09) and family functioning (p = .025, ηp² = .08) remained statistically significant after multiple imputation.
  • Reliable Change Index analysis revealed reliable improvement in 43% of the CBT group compared with 10% in the TAU group, with all improved CBT participants belonging to the digital booster subgroup.
