ABSTRACT
Objective@#To explore dynamics of parenting styles of adolescents from 1999 to 2019 from the perspective of intergenerational conflict, to provide support for family education and adolescent healthy development.@*Methods@#Using a multistage stratified cluster random sampling method, the unified questionnaire was administered to 2 590 students in the same sampling junior and senior high schools in 1999, 2009, and 2019 using the Egna Minnen av Barndoms Uppfostran own memories of parental rearing practices in childhood(EMBU).@*Results@#Overall there were differences in the nine factors of parenting styles across generations ( F = 12.07-72.52, P <0.01), with decreasing ratings of warmth and understanding of father and mother (F1, M1), over interference of father (F3) over generations(F1:46.72±9.41, 45.87±11.33, 43.61±11.27; M1:51.56±9.38, 51.03±11.59, 46.23± 12.27 ; F3:19.03±4.00, 18.29±4.32, 17.95±4.51), and all other parenting styles rated higher in 2019 than in 2009 and 1999(except for the over protection and over interference of mother, and punishment, firm control of mother). Parenting styles across generations (except for the rejection and denial of father among girls) showed gender difference.The overall gender trend coincided with the total population trend. Parenting styles across generations varied significantly among middle and high school students( F =3.92-47.27, P <0.05 ), changes in F1 and F3 factors coincided with the overall decreasing trend. Factor analysis showed that parenting styles could be classified into two dimensions, with varied factor loading across generation.@*Conclusion@#Intergenerational decreases in parental emotional warmth and paternal interfering are observed in a sex and grade specific manner. Based on the diversity of needs and population differentiation, optimal intervention for comprehensive health development of adolescents are in great need to keep pace with the times and promoting the high quality development of adolescents.
