다변량 잠재성장모형을 활용한 부모의 부정적 양육태도, 초기 청소년의 스마트폰 의존 및 삶의 만족도 간의 종단적 관계

초록

This study examines the longitudinal relationships between negative parenting attitudes, smartphone dependency, and life satisfaction in early adolescents, with a focus on the mediating role of smartphone dependency in the influence of parenting attitudes on life satisfaction. Using longitudinal data from the 3rd (6th grade), 4th (1st year of middle school), and 5th (2nd year of middle school) waves of the 2018 Korean Children and Youth Panel Survey (KCYPS 2018), the study analyzed data from 1,960 adolescents. Data were analyzed with IBM SPSS 27.0 and AMOS 23.0, employing descriptive statistics, Pearson's correlations, and latent growth modeling to assess changes over time in parenting attitudes, smartphone dependency, and life satisfaction. A multivariate latent growth model and AMOS user-defined estimand were used to test the mediating effect of smartphone dependency. Results revealed that while negative parenting attitudes and life satisfaction declined over time, smartphone dependency increased. Initial smartphone dependency partially mediated the relationship between negative parenting attitudes and life satisfaction, and the change in smartphone dependency fully mediated the relationship between changes in parenting attitudes and life satisfaction. These findings highlight the significant role of parenting attitudes in adolescents’ life satisfaction and suggest the need for targeted interventions to reduce smartphone dependency through engaging programs in both family and educational contexts.
