Objective This study aims to understand the current status of parental upbringing styles and internet addiction among college students,and to explore the gender differences in the impact of parental upbringing styles on internet addiction.Methods The Egna Minnen av Banrdonsua Pofsrtran(EMBU)and the Revised Chen Internet Addiction Scale(CIAS-R)were used for the investigation conducted on 187 college students with internet addiction.Results There were significant gender differences in multiple dimensions of parenting styles among college students with internet addiction.Male students scored higher than female students in the punitive and harsh dimension of paternal parenting style(t=3.23,P<0.05)and the rejection and denial dimension(t=2.30,P<0.05).Similarly,male students scored higher than female students in the punitive and harsh dimension(t=3.20,P<0.05)and the rejection and denial dimension(t=2.06,P<0.05)of maternal parenting style.However,female students scored higher than male students in the emotional warmth and understanding dimension(t=-2.12,P<0.05)of maternal parenting style.Correlation analysis indicated that for male students,the dimensions of compulsion,withdrawal,and tolerance in internet addiction were associated with parenting styles,whereas for female students,the interpersonal and health issues and time management problems in internet addiction were correlated with parenting styles.Structural equation modeling analysis revealed different mechanisms for males and females.For male students with internet addiction,paternal emotional warmth and understanding influenced compulsion;paternal and maternal punishment and harshness,along with paternal favoritism,affected withdrawal responses;paternal favoritism,as well as maternal warmth and understanding,punishment and harshness,impacted tolerance.In contrast,for female students with internet addiction,paternal and maternal favoritism and paternal punishment and harshness influenced interpersonal and health issues,whereas maternal punishment and harshness affected time management problems.Conclusion The impact of parenting styles on college students with internet addiction differs in gender.For male college students with internet addiction,dimensions related to parental warmth and understanding,punishment and harshness,and paternal favoritism influence compulsion,withdrawal responses,and tolerance.For female college students with internet addiction,dimensions of parental warmth and understanding,and favoritism affect interpersonal and health issues as well as time management problems.
