This investigation examined the relation between developmental trajectories jointly estimated for social and physical aggression and adjustment problems at age 14. Teachers provided ratings of children's social and physical aggression in Grades 3, 4, 5, 6, and 7 for a sample of 255 children (131 girls, 21% African American, 52% European American, 21%(More)
This paper examines how girls' and boys' different peer cultures in middle childhood may set the stage for challenges in emerging heterosexual romantic relationships in adolescence. Two theoretical frameworks are presented for understanding gender differences in children's same-gender friendships and peer groups in middle childhood: the two cultures(More)
This study examined the relations between facial attractiveness, peer victimization, and internalizing problems in early adolescence. We hypothesized that experiences of peer victimization would partially mediate the relationship between attractiveness and internalizing problems. Ratings of attractiveness were obtained from standardized photographs of(More)
This study examined self-reports of social victimization and parent reports of adjustment for a sample followed from fourth through seventh grades. Different patterns of social victimization experiences were identified; of the 153 students (79 girls) with complete data, 24% reported chronic social victimization, 23% reported transient experiences of social(More)
For a sample followed from age 9-13 (N=281), this investigation examined developmental trajectories for social and physical aggression as measured by teacher ratings. Trajectories for both forms of aggression were estimated first separately, then jointly. Mean levels of both social and physical aggression decreased over time for the overall sample, but with(More)
This article presents an innovative method for capturing the content of adolescents' electronic communication on handheld devices: text messaging, e-mail, and instant messaging. In an ongoing longitudinal study, adolescents were provided with BlackBerry devices with service plans paid for by the investigators, and use of text messaging was examined when(More)
This study examined the relations between facial attractiveness, aggression, and popularity in adolescence to determine whether facial attractiveness would buffer against the negative effects of aggression on popularity. We collected ratings of facial attractiveness from standardized photographs, and teachers provided information on adolescents' social(More)
OBJECTIVE Contrast-enhanced MRI is the preeminent diagnostic test for brain metastasis (BM). Detection of BMs for stereotactic radiosurgery (SRS) planning may improve with a time delay following administration of a high-relaxivity agent for 1.5-T and 3-T imaging systems. Metastasis detection with time-delayed MRI was evaluated in this study. METHODS(More)
An upward extension of the Revised Social Experience Questionnaire (Paquette & Underwood, 1999) was tested in a sample of adolescents followed longitudinally from 7th through 10th grade. We hypothesized that a 2-factor model with overt and social victimization factors would fit the data better than would a unidimensional model (a single general(More)
The authors examined whether early adolescents (N = 90) solicit self-enhancing feedback (i.e., positive feedback) or self-verifying feedback (i.e., feedback congruent with self-views, even when these views are negative). Sixth, seventh, and eighth graders first completed a self-perception measure and then selected whether to receive positive or negative(More)
