Parental knowledge trajectory and its relationships with parental warmth and adolescent disclosure for Korean adolescents

The purpose of this study was to expand the knowledge base on parental knowledge by assessing a developmental trajectory and factors that might predict parental knowledge among Korean adolescents. To address this purpose, the current study assessed changes in parental knowledge during the transition to adolescence using hierarchical linear modeling (HLM). In addition, parental warmth and adolescent disclosure were considered as time-variant predictors of knowledge. The data from Korea Youth Panel Survey (KYPS) of Grade 4 students who were followed for five years was analyzed. The results indicated that there was a significant average increase followed by a slight decrease in parental knowledge over time; that is, the data followed a quadratic trend. Controlling for gender and family structure, the study found that parental warmth and adolescent disclosure had significant effects on parental knowledge over time. The study's results suggest that parental warmth and adolescent disclosure are important elements to be emphasized in prevention and intervention programs that promote parental knowledge.
