본 연구는 자녀의 역기능적 특성과 관련된 어머니의 양육행동과 아동의 친사회적 행동의 관계를 알아보고, 그 관계에서 아동의 스마트미디어 중독 및 ADHD관련문제 간의 관련성을 살펴보는 것이다. 이를 위해 한국아동패널 7 차년 자료 중 본 연구에서 사용된 도구에 모두 응답한 537명을 대상으로 각 변인들의 기술통계 및 상관관계를 기초작업의 일환으로 살펴보았고, 본 연구문제 검증을 위해 PROCESS Macro version 4.2(Model 6)로 직렬다중매개효과를 분석하였다. 분석 결과 첫째, 아동의 친사회적 행동에 대한 어머니의 역기능적 양육태도의 영향력이 유의하지 않았다. 둘째, 어머니의 역기능적 양육태도와 아동의 친사회적 행동 간 관계에서 스마트미디어 중독과 ADHD관련문제 각각의 매개효과가 유의하였다. 셋째, 어머니의 역기능적 양육태도와 아동의 친사회적 행동 사이 스마트미디어 중독과 ADHD관련문제의 직렬다중매개효과가 유의하였다. 본 연구 결과는 어머니의 역기능적 양육행동과 자녀의 친사회적 행동의 관계에서 아동의 스마트미디어 중독과 ADHD 관련문제가 중요한 영향을 미친다는 근거를 제시함으로써 아동의 친사회적 행동 증진 방안의 기초 자료로 활용가능할 것으로 기대된다.

Objectives: The coronavirus disease 2019 pandemic and its associated societal responses are anticipated to have wide-ranging effects on youth development and mental health. Depression, anxiety, and attention deficit hyperactivity disorder (ADHD) are the three most common mental health problems among university students. Many factors that can threaten mental health during the outbreak affect these three conditions, as well as sleep conditions, in undergraduate students. Thus, determining how these abrupt changes in students' circumstances impact their mental health is very important from a public health perspective. Methods: We investigated the usual conditions and changes in ADHD symptoms during the outbreak, in relation to depressive and sleep-related symptoms among undergraduate students. A total of 252 students, primarily juniors, completed the online survey. Results: The results showed that 12% of the students exceeded the cut-off score of the ADHD questionnaire before the pandemic. Approximately 6%-21% of the university students, especially those with ADHD traits, rated their ADHD behaviors as worse during the outbreak than that before the outbreak. Conclusion: Female students and undergraduates with ADHD traits are more susceptible to experiencing further deterioration of ADHD (inattention) symptoms during the pandemic. In cases where it is difficult to intervene with ADHD symptoms, approaching circadian rhythm or depression will be of considerable clinical use.

As smartphone use is increasing within the middle-aged population, society should pay closer attention to the mental health problems associated with smartphone addiction. This study examines the possibility that depression, anxiety, and ADHD can be interpreted not only as negative aspects, but also as positive aspects, in an addiction-related individual. We used habitual and addictive smartphone behavior as the dependent variables; anxiety, ADHD, depression, and habitual smartphone use as the independent variables; and self-control as a moderating variable. Depression and ADHD in smartphone users were found to be associated with higher levels of addictive smartphone use. Anxiety was having negative effect on addictive smartphone use. However, habitual smartphone use didn't significantly affect addictive smartphone use. Further analysis indicated that depression, anxiety, and ADHD have mediating effects on habitual smartphone use. This study confirmed that psychological factors in adults, as well as habitual/addictive smartphone use and self-control, significantly influence smartphone overdependence.

Ethanol exposure during gestational period is related to growth retardation, morphological abnormality, and even in neurological abnormalities including attention deficit/hyperactivity disorder (ADHD)-like behaviors on offspring. However, relatively little is known about the effects of maternal ethanol consumption prior to conception on their offspring. In this study, we investigated whether maternal ethanol administration during preconceptional phase produces ADHD-like behaviors in the rat offspring. Sprague-Dawley (SD) female rats were administrated ethanol via intragastric intubation with dosing regimen of 6 g/kg daily for 10 consecutive days and treated female rats then mated with non-treated male SD rats after 8 weeks. Another group subjected to the same procedure as those conducted on ethanol treated group except the saline administration instead of ethanol. Offspring was tested for their ADHD-like behaviors using open field test, Y maze test and impulsivity test that is performed in the aversive electronic foot shock paradigm. Offspring of preconceptional ethanol treated (EtOH) group showed hyperlocomotive activity, attention deficit and impulsivity. And reduction of striatal dopamine transporter (DAT) level was observed by Western blot in the EtOH group, compared to control (Con) group, while the immunohistochemical analysis exhibited increased expression of norepinephrine transporter (NET) in the frontal cortex. These results suggest that maternal ethanol consumption in the preconceptional phase induces ADHD-like behaviors in offspring that might be related to the abnormal expression of DAT and NET in rat.

Objective: The purpose of this research was to examine the prediction models of conflict and intimacy in teacher-child relationships based on decision tree analysis. Methods: The participants were 297 preschool children from ages three to five including 166 boys and 131 girls. Teacher-child relationships were measured by the Student-Teacher Relationship Scale(STRS). Physical aggression, relational aggression, social withdrawal, and prosocial behaviors were measured by teacher ratings. Moreover, ADHD-RS(Attentive Deficit Hyperactivity Disorder Rating Scale) was used to measure ADHD. The data was analyzed with decision tree analysis. Results: According to the prediction model for teacher-child conflict, the significant predictors were physical aggression and social withdrawal. According to the prediction model for teacher-child intimacy, the significant predictors were prosocial behaviors and relational aggression. However, children's age, gender and ADHD were not significant predictors. Conclusion/Implications: The findings suggest that social behaviors may be closely related with teacher-child relationships for preschool children. Based on the results of this study, intervention suggestions were made.

Objectives: This study investigated the relationship between suicidal behavior and the use of methylphenidate (MPH) or atomoxetine (ATX) in patients with attention deficit hyperactivity disorder (ADHD). Methods: The Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines were used to conduct a meta-analysis. The Physiotherapy Evidence Database scale was used to score the quality of the studies. Results: Nine studies were included in this quantitative analysis. The analysis included 602864 patients with ADHD (521125 and 81739 patients were taking methylphenidate [MPH group] and atomoxetine [ATX group], respectively) and 19230 healthy controls. The overall estimates were in the order of the control, MPH, and ATX groups; however, no statistically significant between-group difference was observed in the incidence of events (p=0.553 for control vs. MPH; p=1.000 for control vs. ATX; p=1.000 for MPH vs. ATX). Conclusion: The rate of suicidal behavior was higher in the ADHD groups treated with MPH and ATX than in the control group. However, no statistically significant difference was observed between the ADHD groups treated with MPH and ATX, and the control group. Therefore, MPH and ATX did not increase suicidal behavior.

Oroxylin A is a flavonoid isolated from Scutellaria baicalensis, which is one of the most important medicinal herbs in traditional Korean medicine. In this study, we investigated the psychopharmacological activities of oroxylin A using the open field, rota-rod, balanced wire and plus-maze tests in Spontaneously Hypertensive Rats (SHR) and Wistar Kyoto Rats (WKY). Oroxylin A reduced hyperactivity in SHR (ADHD animal model) although it tended to increase locomotor activity in WKY. Methylphenidate did not reduce hyperactivity. Oroxylin A alleviated impulsive behaviors such as rearing, the percentage of moving time to the central area and the tendency to move into an unstable condition (open area in elevated plus-maze). Methylphenidate also reduced the percentage of staying time in the central area and the tendency to move into an unstable condition. Both oroxylin A and methylphenidate enhanced motor attention in SHR and WKY. Oroxylin A antagonized the muscimol ($GABA_A$ receptor agonist)-induced $Cl^-$current and its action was similar to that of bicuculline ($GABA_A$ receptor antagonist). The effects of oroxylin A may be caused by the antagonism at the $GABA_A$ receptor. Thus, oroxylin A may be a candidate of drug for treatment of ADHD.
