This study explored the important role of parenting styles on college student adjustment. The purpose of the study was to scrutinize the direct and indirect effects of parenting styles on social, emotional, and academic adjustments, along with the potential mediating role of personal self-esteem. We collected data by convenience sampling of 300 undergraduate students from a major public university in a Southwestern city of the United States. Study results demonstrated that the authoritative parenting style had the strongest influence on college students' self-esteem, which improved overall college students' social, emotional, and academic adjustment. The findings of this study may help parents, administrators, and counselors at universities to better understand the importance of parenting styles.
