Prediction of adolescent suicidal ideation after the COVID-19 pandemic: a nationwide survey of a representative sample of Korea

AUTHOR(S)
Haewon Byeon

Published: July 2022   Journal: Frontiers in Pediatrics

This study developed a model to predict groups vulnerable to suicidal ideation after the declaration of the COVID-19 pandemic based on nomogram techniques targeting 54,948 adolescents who participated in a national survey in South Korea. This study developed a model to predict suicidal ideation by using logistic regression analysis. The model aimed to understand the relationship between predictors associated with the suicidal ideation of South Korean adolescents by using the top seven variables with the highest feature importance confirmed in XGBoost (extreme gradient boosting). The regression model was developed using a nomogram so that medical workers could easily interpret the probability of suicidal ideation and identify groups vulnerable to suicidal ideation.

Jeopardized mental health of children and adolescents in coronavirus disease 2019 pandemic

Published: June 2022   Journal: Clinical and Experimental Pediatrics
The coronavirus disease 2019 (COVID-19) outbreak became a worldwide pandemic in 2020. Social distancing measures, such as self-quarantine, lockdowns, and school closures, which have proven efficacy in various pandemic situations, remain in use in Korea. These measures prevented viral transmission to some extent; however, adverse effects have also resulted. First, the negative effect of social isolation on mental health is evident. This influences the psychiatric milieu of parents and children directly and indirectly. The most stressful factor among Korean youth was the restriction of outdoor activities. Increasing parenting burden result in increased screen time among youth, and social isolation created depressive mood with symptoms similar to those of attention deficit hyperactivity disorder and anxiety. Second, symptoms of posttraumatic stress disorder (PTSD) and somatization are prevalent among children and adolescents. The sense of threatened health and life during the pandemic, one symptom of PTSD, is a strong risk factor for somatization. Finally, the increased pattern of child abuse in pandemic indicates increased levels of emotional/psychological abuse and nonmedical neglect. Social isolation makes people less aware of these events. Because pediatricians evaluate pediatric patients and their families, they should regularly assess emotional/stress factors, especially when somatization is prominent during the pandemic, and cautiously recommend that families seek advice from mental health professionals when warranted. Primary physicians must understand the characteristics and aspects of child abuse in the COVID-19 pandemic, make efforts to identify signs of child abuse, and deliver accurate information and preventive strategies for child abuse to caregivers, thereby functioning as a professional guardian. To promote the mental health of parents and children during the COVID-19 pandemic, more research and cooperation among health professionals, families, governments, and schools are needed in the future.
Impact of COVID-19-related stress on preschool children's internalizing and externalizing problem behaviors: the indirect effect of mother's depression and parenting behavior

AUTHOR(S)

Published: June 2022   Journal: Child Indicators Research
The COVID-19 pandemic is affecting families and children worldwide. Experiencing the pandemic leads to stress in families resulting from fear of infection and social isolation derived from social distancing. For families raising preschoolers, the prolonged closure of childcare centers puts additional childcare burden on family members, especially mothers. Due to the limited research exploring the impact of COVID-19 on preschool children’s problem behaviors, this study examines the association between stress due to COVID-19 and preschool children’s internalizing and externalizing problem behaviors related to mother’s depression and parenting behavior. The study sample included data collected from 316 South Korean mothers raising preschool-aged children aged 3 to 5.

Published: May 2022   Journal: Child Psychiatry & Human Development
This study investigated how parental depression, parental self-care, family conflict, and parental fear of COVID-19 are associated with children’s screen time during the COVID-19 pandemic. Data were collected online among South Korean families, resulting in 246 parents (59% fathers) with children between 6 and 12 years of age. Path analysis and multi-group structural equation modelling of fathers and mothers were conducted. Parent’s fear of COVID-19 was positively associated with parental depression. Parent’s fear of COVID-19 and parental depression were negatively related to parental self-care, which was negatively linked to family conflict. Family conflict was positively associated with children’s screen time.
