Aim: Emotion dysregulation (ED) is frequently observed in attention deficit and hyperactivity disorder (ADHD). People suffering from ADHD have difficulty with ED, and the nature of the relationship between the two is an important area of research. In this study, we aimed to investigate ED in mothers of children with ADHD. Material and Methods: Seventy-two children (n = 49 male, n = 23 female) with a diagnosis of ADHD and their mothers participated in the study Clinical Interview was used for the the Diagnostic and Statistical Manual of Mental Disorders (fourth edition (DSM-IV) (SCID-II), Child Anxiety Sensitivity Index (CAST)). Mothers completed the McMaster Family Assessment Device (FAD) and Conners' Parent Rating Scale (CPRS-48) as applied to individuals. Results: The distribution of SCID-II diagnoses in mothers was as follows: without diagnosis 73.6 %, avoidant 8.3%, histrionic 5.6%, obsessive-compulsive 5.6%, passive-aggressive 2.8%, dependent 1.4%, self-defeating 2.8%. CASI scale points were higher in children with SOD II (+/- 31.73, +/- 6.98 vs 27.84, +/- 7.19, p = .037). There was no difference in the subscales of Conners and McMaster scales according to the presence or absence of SCID-II diagnoses. Discussion: The relationship of ED with ADHD and personality disorders has been frequently noted. However, a number of questions remain unaddressed about the association between ADHD and ED.
