Professor Yoon-Sun Han's research lab specializes in adolescent development and youth well-being in South Korea, with a strong focus on the social and environmental factors influencing youth psychosocial outcomes. The lab investigates bullying dynamics—including perpetration, victimization, and cyberbullying—through both traditional survey data and innovative social big data analytics. It also explores the protective roles of family, school, and neighborhood social bonds in shaping adolescent behavior, particularly in relation to substance use and mental health. Drawing on social control theory and social disorganization theory, the lab integrates longitudinal, nationally representative datasets to uncover developmental trajectories and contextual risk factors.

15The present study analyzed the relationship between various parenting practices and an array of adolescent psychosocial outcomes in South Korea, while controlling for demographic, family, school, and neighborhood factors. Analyses were based on five waves of the nationally representative Korea Youth Panel Survey using 3,263 youth ( Person Years = 13,121). All parenting (warmth, monitoring, and hostility) and youth’s psychosocial (confidence, depressive symptoms, and aggressive behaviors) measure
As the contemporary phenomenon of school bullying has become more widespread, diverse, and frequent among adolescents in Korea, social big data may offer a new methodological paradigm for understanding the trends of school bullying in the digital era. This study identified Term Frequency-Inverse Document Frequency (TF-IDF) and Future Signals of 177 school bullying forms to understand the current and future bullying experiences of adolescents from 436,508 web documents collected between 1 January
AIMS: This study examined latent trajectories of bullying perpetration and victimization, and identified neighborhood antecedents of these trajectories among South Korean adolescents. METHODS: Nationally representative individual-level data from waves 2 to 6 (middle school to high school) of the Korean Children and Youth Panel Survey were merged with neighborhood-level data drawn from the Korean Census and the Korean Ministry of Education. Latent class growth analysis (N = 2,178) and logistic re
This study examined the association between school bonds and the onset of substance use among adolescents in South Korea. Based on Hirschi's social control theory, this study tested the roles of teacher attachment, educational aspiration, extracurricular activities, and rule internalization--four elements of social bonds within the school setting--in delayed initiation of alcohol drinking and cigarette smoking. Discrete-time logistic regression was used to analyze five waves of the Korea Youth P
Based on Hirschi’s social control theory (1969), this study examined the relationship between attachment (an element of social bonds) and the onset of substance use among South Korean adolescents. Using discrete-time logistic regression, the study investigated how attachment to parents, teachers, and close friends was associated with the timing of first alcohol and cigarette use. A nationally representative sample of Korean youth from five waves of the Korea Youth Panel Survey ( N = 3,449 at bas
This cross-national research investigated nationally representative adolescents from South Korea and the United States, explored similarities and differences in latent profiles of bullying victimization between countries, and examined individual- and school-level variables that predict such latent profiles supported by the Social Disorganization Theory. The fourth-grade sample of the 2015 Trends in International Mathematics and Science Study from South Korea ( N = 4,669) and the United States (
The absence of an approach which encompasses several micro-systems in Korea may leave important factors of youth risk behaviors undetected. Thus, an examination of a broad set of ecological factors within the micro-system--including individual characteristics as well as immediate family, peer, and school environments surrounding the youth--that is associated with juvenile theft is warranted. The current study analyzes a rare dataset of 176 youth who were arrested for theft and a matching non-the
Despite extensive formal legislation designed to protect youths from engaging in health-risk behaviors, underage substance use and extreme forms of aggression are prevalent in Korea. This study examined the ways social capital—an informal relational resource—may contribute to delayed onset of health-risk behaviors among Korean adolescents. Analyses were conducted using five consecutive waves of the Korean Youth Panel Survey (N = 3,449), a nationally representative sample of adolescents in Korea.
=918). Probit and negative binomial models were applied to predict the probability of ever-use and the average number of drinks consumed in the past 30 days. Results supported the profound role of peer-relationships in the development of youth drinking behavior. Particularly, peer pressure seemed more important in predicting alcohol ever-use than the frequency of drinking. Simultaneously, parents, especially fathers, played a crucial protective role. Policies aimed at preventing various drinking
