Ecological Factors Influencing Emotional/Behavioral Problems and Self-Concept in Adolescents from Low-Income Families in South Korea.

In this study, we examined emotional/behavioral problems and self-concept in adolescents from low-income families in Korea; additionally, we identified ecological factors associated with these traits. This descriptive study employed an ecological model to analyze data from the Korean Children and Youth Panel Survey. A nationwide stratified multistage cluster sampling methodology was used. Overall, 2534 first-year middle school students were included in the survey, and the survey was conducted from 2010 to 2016. Hierarchical multiple regression models were generated. The mean score of emotional/behavioral problem has been changed from 2.20 (2011), 2.15 (2013), to 2.11 (2015) out of 4, and the mean score of self-concept has been changed from 2.73 (2012), 2.73 (2014), to 2.77 (2015) out of 4. Factors that influenced emotional/behavioral problems and self-concept among adolescents were health perception and academic achievement (only associated with self-concept) at the intrapersonal level and parenting style, peer attachment (only associated with self-concept), and relationships with teachers at the interpersonal level. These results may be used to inform the development of interventions designed to decrease emotional/behavioral problems and improve positive self-concept in adolescents from low-income families.
