This study investigates the relationship between three variables: parenting style, locus of control,and self-worth among college students, revealing their underlying psychological mechanisms. The studysurveyed 170 undergraduate students using a questionnaire survey method to explore the relationshipbetween parenting styles, locus of control, and self-worth. It was found that the surveyed college studentshave a warm and harmonious family atmosphere, high internal control, and a high sense of self-worth.The three variables of parenting style, locus of control, and self-worth are correlated pairwise. Theparenting style affects the self-worth of college students, and the locus of control plays a partial mediatingrole in the influence of parenting style on self-worth. The results indicate that college students underpositive parenting exhibit more internal control and higher self-worth. The parenting style can directlyaffect one’s sense of self-worth, or indirectly affect one’s sense of self-worth by influencing the locus ofcontrol.
