Parental involvement in education has significantly contributed to positive youth development. This study applied Epstein's six constructs of parental involvement (parenting, communicating, volunteering, decision making, learning, and collaborating) and examined the effects of different types of parental involvement on children's emotions and behaviors. A cross-sectional self-administered survey was given to 317 parents of elementary school students. Parents with higher incomes were more involved at home and school, and parents with a younger child were more likely to be involved in parenting and learning at home. Overall, parental involvement was shown to be a statistically significant predictor of a child's suspension, negative behavior, or prosocial behavior. It is expected that young children's behavioral problems may often adversely affect their social development in adolescence. Hence, collaborative efforts by educators, parents, policy makers, and mental health professionals should be aimed at finding effective solutions for poor academic motivation, bullying or aggression, and mental disorders.
