The Associations Between Parenting and Bullying Among Children and Adolescents: A Systematic Review and Meta-Analysis

Parenting styles are closely related to bullying behavior in children and adolescents. However, differences in study design and inconsistent results create uncertainty regarding the relationship between parenting and bullying. This study aimed to evaluate the associations between four parenting styles and bullying perpetration/victimization through a meta-analysis, identifying sources of study heterogeneity by examining moderating effects. This meta-analysis included 107 studies with 624 effect sizes and 162203 participants (49.28% female, M_age = 13.51, SD_age = 2.56). Results indicated that positive parenting was negatively correlated with bullying perpetration and victimization, while negative/harsh parenting and uninvolved parenting were positively correlated with bullying perpetration and victimization. A positive correlation was also found between psychologically controlling parenting and bullying victimization (not perpetration). Significant moderating variables included the identity of the caregiver, country of origin, ethnic group, reporter of parenting, reporter of bullying, and measure of bullying. Specifically, the mother's psychological control was more related to bullying perpetration and victimization than the father's. Compared to other countries and ethnic groups, the relationships between psychologically controlling parenting or negative/harsh parenting and bullying were more positive in studies of Chinese and Asians. The relationship between negative/harsh parenting and bullying demonstrated a greater effect size in self-reported measures of parenting and bullying. Finally, a stronger correlation was found between negative/harsh parenting and bullying victimization when using the Olweus Bully/Victim Questionnaire to measure bullying. The current study deepens the understanding of the relationship between different parenting styles and bullying, emphasizing that adopting appropriate parenting, particularly positive parenting behaviors, helps mitigate bullying issues and achieve positive developmental outcomes for children and adolescents.
