Abstract Objective To further expand on previous smaller study (with 25 participants) that found that children with ADHD, Mixed Type, improved their cognitive functioning after 12 weeks of CBT. Method In the current study 68 children (20 girls) diagnosed with ADHD, mixed type, between the ages of 9 and 12 (M = 10.25, SD = 1.88) were assessed with the WISC-V, CBCL, TEA-Ch2, and CPT-2, clinical interview with parents and teachers before the beginning of CBT. The same assessment was repeated 14 weeks later, following 12, weeks of individualized CBT. CBT included thought restructuring, impulse control exercises, relaxation techniques, and mindfulness exercises. Results Average Based Change (ABC) was employed and significant improvements, with large Cohen’s d (. 80) effect size, were detected for Working Memory, Hyperactivity, Externalizing Behavior, Impulsivity, Selective, Sustained, and Everyday Attention. Ratings, during interviews, by teachers, psychologists, and parents agreed also that there was a significant clinical improvement. Conclusion In agreement with the first study, and other literature, CBT seems to be an important tool in helping significantly children with ADHD, Mixed Type, improve in behavior and cognitive functioning. More studies with younger and older children are needed to cement the utility of CBT with children and teens.
