Objectives: Maternal depression negatively affects depression and anxiety symptoms in the offspring. This study examined the association between maternal depression and their adolescent offspring depression and anxiety, as well as the mediating role of emotional trauma in determining the association. Methods: Participants were 237 mothers (46.08±5.00 years) and their adolescent offspring (16.54±1.51 years). The participants completed the Beck Depression Inventory-II, Early Trauma Inventory Self Report-Short Form, Center for Epidemiological Studies Depression Scale for Children, and the Screen for Children’s Anxiety Related Disorders. The mediating effect of emotional trauma on offspring was explored using mediation analysis. Results: Maternal depressive symptoms were significantly correlated with adolescent offspring traumatic experiences, as well as with their depressive and anxiety symptoms. Mediation analysis results showed that emotional trauma of offspring significantly mediated the effect of maternal depression on their depressive and anxiety symptoms. Conclusion Findings indicate that maternal depression was significantly associated with depressive and anxiety symptoms in adolescent offspring, mediated by their emotional trauma. Future research is needed to investigate pathways and intervention strategies to prevent the intergenerational transmission of emotional problems.

Objectives: This study investigated the relationship between exposure to endocrine-disrupting chemicals (EDCs), specifically phthalates, bisphenol A, bisphenol F, and bisphenol S, and the severity of attention-deficit/hyperactivity disorder (ADHD) symptoms using neuropsychological tests in children diagnosed with ADHD. Methods: This study included 67 medication-naïve children with ADHD aged 6–16 years. The urinary concentrations of EDCs were measured, and ADHD symptom severity was evaluated using neuropsychological tests and clinical symptom scale measurements. The Jonckheere–Terpstra test, Pearson and Spearman correlation analyses, linear regression models, and multiple regression models were used to examine the relationship between EDC exposure and ADHD symptoms. Results: A significant correlation was observed between urinary phthalate metabolite concentrations and commission error T-scores in the visual Advanced Test of Attention test. No significant associations were found with other neuropsychological indicators or bisphenol levels. Conclusion Phthalate exposure affects impulsivity in children with ADHD, which is consistent with the results of previous studies that used parental surveys. However, bisphenols are not clearly associated with ADHD symptoms, which is consistent with the results of previous studies.

Objectives: This study aimed to estimate the prevalence of Internet addiction (IA) among Korean adolescents and examine its association with psychiatric comorbidities and mental health symptoms. Methods: A total of 270 adolescents and their parents participated in this study. Parents completed the Internet Addiction Proneness Scale for Youth: Observer Version and the Diagnostic Predictive Scales, whereas adolescents completed the Center for Epidemiological Studies Depression Scale for Children, the Screen for Child Anxiety-Related Disorders, and the Youth Self-Report. Group differences in psychiatric disorders and mental health symptoms across IA levels were analyzed. Results: Of the participants, 86.3% were classified as general, 11.1% as potential high risk, and 2.6% as high risk for IA. The high risk IA group exhibited significantly higher rates of attention-deficit/hyperactivity disorder (42.9%), major depressive disorder (26.3%), and social anxiety (14.3%) as well as greater attentional and social difficulties. Effect sizes for group differences were small to moderate (ε2 = 0.041 for social problems; ε2 =0.033 for attentional problems). IA scores were positively correlated with attentional difficulties and anxiety. Anxiety was a significant predictor of IA in the regression analysis. Conclusion Adolescents with high IA risk exhibited elevated psychiatric comorbidities and mental health difficulties, with anxiety showing an independent association with IA. These findings suggest incorporating anxiety-management components into IA prevention and care. Given the small sample size of the high risk IA group, caution is warranted when generalizing these findings.

Objective: To examine the effect of mobile neurofeedback training on the clinical symptoms, attention abilities, and execution functions of children with attention deficit hyperactivity disorder (ADHD). Methods: The participants were 74 children with ADHD aged 8−15 years who visited the Department of Child and Adolescent Psychiatry at Seoul National University Children’s Hospital. The participants were randomly assigned to the mobile neurofeedback (n = 35) or control (sham; n = 39) group. Neurofeedback training was administered using a mobile app (equipped with a headset with a 2-channel electroencephalogram [EEG] sensor) for 30 min/day, 3 days/week, for 3 months. Children with ADHD were individually administered various neuropsychological tests, including the continuous performance test, Children’s Color Trails Test-1 and 2, and Stroop Color and Word Tests. The effects of mobile neurofeedback were evaluated at baseline and at 3 and 6 months after treatment initiation. Results: Following treatment, both mobile neurofeedback-only and sham-only groups showed significant improvements in attention and response inhibition. In the visual continuous performance test, omission errors decreased to the normal range in the mobile neurofeedback-only group after training, suggesting that mobile neurofeedback effectively reduced inattention in children with ADHD. In the advanced test of attention, auditory response times decreased in the mobile neurofeedback + medication group after training, but increased in the sham+medication group. Overall, there were no significant between-group differences in other performance outcomes. Conclusion Mobile neurofeedback may have potential as an additional therapeutic option alongside medication for children with ADHD.

Objectives: Non-suicidal self-injury (NSSI) and suicidal behavior, including suicidal ideation (SI) and suicide attempts, are important predictors of suicide in adolescents. This study aimed to investigate the associations between NSSI, SI, NSSI+SI, mental health problems, and family factors in Korean adolescents in Jeju Island, with an emphasis on key findings. Methods: A total of 561 adolescents completed self-report questionnaires regarding demographics, NSSI, SI, suicidal behavior, perceived family functioning, and mental health problems, which were assessed using Center for Epidemiological Studies Depression Scale for Children, Screen for Children Anxiety-Related Disorders (SCARED), and Youth Self-Report (YSR). Data were analyzed using descriptive statistics, one-way analysis of variance, chi-square test, post-hoc analyses, and multivariate logistic regression. Results: In this study, 22.3% of adolescents reported either NSSI or SI, with 5.5% reporting NSSI and 20.7% reporting SI. Combined (NSSI+SI) group showed a significantly higher SCARED score, anxiety/depression, thought problems, attention problem, and rule breaking on YSR than did the SI only group. Higher level of depression and anxiety were significantly associated with NSSI and SI. Female sex and perceived family dissatisfaction were significantly associated factors for SI, but not for NSSI in multivariate logistic regression. Conclusion This study provides insights into the clinical characteristics and associated factors among adolescents with NSSI, SI, and NSSI+SI in Jeju Island. Identifying these results can inform the development of targeted prevention and intervention strategies to mitigate the negative consequences of these behaviors and contribute to a better understanding of the role of family in this context.

Under the Ministry of Health and Welfare of the Republic of Korea, the National Autism and Developmental Disorder Centers for people with developmental disabilities are gradually expanding. The headquarters of the National Autism and Developmental Disorder Center provides support for education, training, and research, and several centers have been effectively operating since 2020. This study aimed to provide practical recommendations and guidelines for specialists such as clinical psychologists, child psychiatrists, allied professionals, community workers, and related administrators. It was developed as a guideline to promote early diagnosis, provide important information on integrated treatment, and assist people with developmental disabilities in Korea to make the best decisions for their quality of life.
