Commentary* by Dr. Margaret Weiss: Combination CBT and medication treatment for adults with ADHD has unique advantages – but not often available.
The study aimed to evaluate the efficacy of group cognitive behavioural therapy (CBT) in medicated adults with attention-deficit/hyperactivity disorder (ADHD) with a multidimensional evaluation and follow-up to week 36. Ninety-eight adult ADHD were randomly allocated to the CBT combined with medication (CBT + M) group or the medication (M) only group.
The primary endpoint was the ADHD-Rating Scale (ADHD-RS). Secondary endpoints included emotional symptoms, self-esteem, automatic thoughts, quality of life (QoL), and executive function (EF).
The outcome measures were obtained at baseline (T1), after the 12-week CBT treatment (T2), and at two follow-up time points (week 24, T3, and week 36, T4). Compared to the M-only group, the patients in the CBT + M group showed an overall significantly greater reduction from baseline in ADHD core symptoms (ADHD-RS total score at T3, and inattention subscale at T2 and T3), depression and anxiety symptoms (T2-T4), state anxiety (T2 and T3) and trait anxiety (T2), automatic thoughts questionnaire at T3, and QoL (physical domain, psychological domain, and social domain, most significant at T3 and weakened at T4).
These findings further confirmed the efficacy of CBT on multiple dimensions and verified improvements in automatic thinking in adult ADHD. The superiority of the combination treatment mainly manifested in reduced inattention, emotional symptoms, and maladaptive thoughts and improved QoL.
