Theories and research on adolescent development and psychopathology frequently characterize adolescent girls as "vulnerable" and "at-risk." Although adolescent girls do consistently report disproportionate levels of internalizing behaviors (e.g., depression, anxiety) compared to boys, the dearth of research on adolescent girls' strengths and resiliency has resulted in an unbalanced characterization of today's girls. This study focused on internal resiliency traits among adolescent girls and sought to examine whether significant differences existed by gender, ethnicity and age among a diverse adolescent sample. Analyses of data collected from 303 adolescents who completed the Resiliency Scale for Children and Adolescents (RSCA) revealed few significant gender differences across 15 measures of resiliency. These results suggest that adolescent boys and girls as groups share similar levels of skill and struggle in the areas of mastery, relatedness and emotional impairment. Analysis of data by ethnicity revealed a few significant differences for girls but not for boys in the study. Analysis by age revealed that boys and girls both experience a decline in skills in many domains between the ages of 13 and 14. This age shift was especially significant among boys in the study.
