Attention deficit hyperactivity disorder (ADHD) is a developmental disorder with emotional and cognitive symptoms.
This study aimed to investigate the effect of dialectical behavioural therapy (DBT) on cognitive and emotional aspects of ADHD in adults.
A quasi-experimental pre-test/post-test design with a control group (waiting list) was applied. Forty participants were selected for the study among the target population of adult ADHD patients. They were randomly assigned to the control and experimental (group DBT) groups. The Adult ADHD Self-Report Scale (ASRS), Tower of London, Stroop test, Wisconsin sorting test, Continuous Performance Test, Eysenck Impulsivity Test, and Difficulties in Emotion Regulation Scale (DERS) were used for assessment purposes. The data analysis was conducted using SPSS-23 and the MANCOVA method.
The results showed that DBT was significantly effective in improving emotion regulation (31.4%), impulsivity (37.4%), Stroop scores (21.9%), attention and concentration (31.8%), and hyperactivity (41%) compared to the control group. However, there was no significant difference in the subscales of the Tower of London, Wisconsin test and the attentional subscale of the ASRS.
It can be inferred from this research that DBT can significantly reduce the emotional difficulties of adults with ADHD, but may not be very helpful for the cognitive aspects of this disorder.
