Childhood trauma can lead to various psychological and cognitive symptoms. It has been demonstrated that high frequency EEG powers could be closely correlated with inattention. In this study, we explored the relationship between high frequency EEG powers, inattention, symptoms of adult attention deficit hyperactivity disorder (ADHD), and childhood traumatic experiences. A total of 157 healthy Korean adult volunteers were included and divided into two groups using the Childhood Trauma Questionnaire (CTQ) score. The subjective inattention scores, ADHD scale, and anxiety and depression symptom were evaluated. Electroencephalogram (EEG) was recorded and quantitative band powers were analyzed. The results were as follows: 1) the high CTQ group showed significantly increased delta, beta1, beta2, beta3, and gamma, and significantly decreased low alpha power compared to the low CTQ group, 2) the high CTQ group had higher inattention score compared to the low CTQ group, 3) the high CTQ group had higher adult ADHD scores, 4) CTQ scores showed significant positive correlations with inattention scores, and adult ADHD scores, 5) unexpectedly, the inattention scores showed significant positive correlations with beta powers and a negative correlation with low alpha power, and 6) The moderated mediation model was confirmed: the depression fully mediated the path from state anxiety to inattention, and the CTQ significantly moderated the pathway between anxiety and depression. Our results show the possibility that childhood adversity may cause subjective inattention and adult ADHD symptoms. Depressive symptoms fully mediated the path from anxiety to inattention, especially in those who report severe childhood

Objective This study standardizes the Parental Stress Scale (PSS) for Republic of Korean parents of children with attention-deficit/hyperactivity disorder (ADHD) and verifies its reliability and validity.Methods Data from 160 parents of children with ADHD who completed the following self-reported questionnaires were analyzed: the Korean ADHD Rating Scales, the Patient Health Questionnaire-9, the State–Trait Anxiety Inventory, the PSS, and the Global Assessment of Recent Stress Scale. All scale items were measured for reliability and validity, and the appropriate factors for measuring stress in Korean parents with ADHD children were extracted.Results Exploratory and confirmatory factor analyses derived two sub-factors and 11 items. Goodness of fit was confirmed, and the scale was deemed suitable for explaining stress in parents of children with ADHD.Conclusion In this study, the validity and reliability of the K-PSS-ADHD were investigated. We expect that the K-PSS-ADHD will be used as a basis for future studies on stress in parents of children with ADHD.
