Relationships of the adolescent who experiences group pressure. The aim of the investigation was to determine how group pressure is related to the relationships of the adolescent. The relationships of adolescents are mainly those with parents, friends and with themselves (self-concept). An empirical investigation was carried out involving 462 learners from Grades 8 to 12. A questionnaire was developed measuring parent-child relationship, relationship with friends, self-concept and group pressure. The results of the investigation showed significant negative correlations between all the social relationships and group pressure. From the regression analysis it could be concluded that self-concept was the most important variable accounting for 35% of the variance of group pressure. Group pressure seems to decrease from Grade 8 to Grade12, but self-concept does not show an increase during this period.
