The Relationship Between Parenting Patterns and Parental Knowledge Regarding Sibling Rivalry Incidents in Preschool Children Aged 3-5 Years at Al Azhar Kindergarten 22

Background : Sibling rivalry is competition or jealousy between siblings that often occurs in preschool children due to differences in parental attention and parenting styles, and can affect children's social-emotional development. This study aims to determine the relationship between parenting styles and parental knowledge with the incidence of sibling rivalry in children aged 3–5 years at Al Azhar 22 Kindergarten. Method : This study used a quantitative method with a cross-sectional design . The study population was parents who have preschool children aged 3–5 years with a sample of 40 respondents taken using the total sampling technique. The research instrument was a questionnaire on parenting styles, parental knowledge, and the incidence of sibling rivalry. Data analysis was carried out univariately and bivariately using the Spearman Rank test. Results : The results showed a significant relationship between parenting styles and the incidence of sibling rivalry (p = 0.000) and a significant relationship between parental knowledge and the incidence of sibling rivalry (p = 0.000). Democratic parenting styles and a good level of parental knowledge tend to reduce the incidence of sibling rivalry. Conclusion: Parenting styles and parental knowledge are significantly associated with the incidence of sibling rivalry in preschool children. Parents are expected to be able to implement appropriate parenting styles and increase their knowledge regarding child development.
