The present study tests a protective factor which may mitigate the negative impact of test anxiety on academic outcomes. This study examines ethnic and racial identity as a moderator of the impact of test anxiety on grades and academic ability self-concept among African American adolescents. The study relies on the existing longitudinal Maryland Adolescent Development in Context Study (MADICS) dataset, a public use dataset collected from 1991-2000. The subsample consists of 533 African American youths in Wave 3 and 399 African American youths in Wave 4. The present study uses two waves of data from participants aged 13 to 18. This study employs self-reported questionnaires of test anxiety, ethnic and racial identity, grades, and academic ability self-concept. Moderation analyses are conducted to test ethnic and racial identity as a protective factor mitigating the impact of test anxiety on later grades and academic ability self-concept, while adjusting for gender, socioeconomic status, and age. Results indicate that ethnic and racial identity moderated the relation between test anxiety and GPA, such that the lower the level of ethnic and racial identity, the more protective it becomes. Discussion centers on potential causes for the unexpected trend in moderation.
