Cognitive behavioural therapy (CBT) involves self-instructional training administered in a group or individual basis, to help the individual with ADHD to develop a more planned and reflective approach to thinking and behaving, including social interactions.1 It can also help individuals adopt a more reflective, systematic and goal-oriented approach to everyday tasks, activities and problem solving, including academic functioning.2

Results from a randomised controlled trial of a CBT group in adolescents with ADHD (n=119; aged 15–21 years) receiving pharmacological therapy with methylphenidate or atomoxetine, showed that:3

  • Patients who received CBT showed significantly reduced symptoms of ADHD compared with the control group on the Clinical Global Impression Self-Report Scale (p<0.001) and the Clinical Global Impression Clinician-Report Scale (p<0.001)3
  • Patients who received CBT showed a significant reduction in functional impairment compared with the control group on the Global Assessment of Functioning (p<0.001) and the Weiss Functional Impairment Rating Scale Parent Version (p<0.05).3

CBT in combination with pharmacological treatment may reduce the symptoms of ADHD in adolescents.3

In a 6-month study of two internet-based CBT modular programmes in adults with ADHD (n=45), 48% of whom were receiving pharmacological therapy,4 participants were assigned to either:

  • Self-help internet-based CBT
  • Self-help internet-based CBT plus weekly group therapy sessions
  • Wait list (control group).

Modules covered topics including behaviour analysis, mindfulness and acceptance, time management, gauging attention span, reducing distractors, organisation and planning, problem solving, behaviour activation, cognitive restructuring and anger control training.

  • Patients in the self-help intervention treatment arm showed significantly greater improvement in ADHD symptoms versus the wait-list control patients on the Current Symptoms Scale – Self-Report Form (p=0.027)4
  • The difference in self-reported symptoms of ADHD observed between patients in the group therapy intervention arm versus the wait-list control patients did not reach statistical significance4
  • Exploratory analysis of the 6-month follow-up scores showed that patients in the self-help intervention treatment arm maintained the improvements in their ADHD symptoms 6 months after treatment.4

A randomised, controlled trial has explored the effectiveness of group-based CBT in adults who were already receiving medication for ADHD (n=86).5 Therapy included three core modules, focusing on:5

  1. Psychoeducation about ADHD, and training on organisation and planning, including problem-solving
  2. Skills to reduce distractibility, such as techniques to time the length of one’s attention span
  3. Cognitive restructuring, involving learning to think more adaptively in situations that cause distress.

Twelve 50-minute sessions of CBT significantly reduced ADHD symptom scores compared with relaxation and educational support, with responders continuing to maintain benefit over a 12-month follow-up period.5

Other group-based approaches to CBT have also been associated with symptomatic improvements in adults with ADHD.

  • In a study of 29 adults with ADHD, 10–11 weekly sessions of cognitive–behaviourally oriented psychological group rehabilitation reduced self-reported ADHD symptoms6
  • Two studies assessing an 8- or 12-week programme of meta-cognitive therapy to target executive self-management skills in 30 and 88 adults with ADHD, respectively, reported reduced symptoms of inattention and improved executive functioning.7,8

There is also some evidence to support the use of CBT approaches in children with ADHD. In a randomised study of boys aged 7–13 years with ADHD (n=25), CBT improved parent perception of hyperactivity in the home and child-rated self-esteem, compared with a supportive therapy control group.9

Some evidence suggests that CBT may enhance activity in neural structures typically affected by ADHD, in a similar manner to treatment with methylphenidate.10 Similarly, data from another small imaging study suggested that CBT may increase grey matter volume in structures typically characterised by volume reduction in ADHD patients, versus an ADHD control group, and that these increases may be associated with attentional performance.11 However, this research is in its infancy and further investigation is warranted.
