To resist and cope with oppression, youth of color may use the process of critical consciousness which involves understanding racial injustices (critical reflection), developing motivation to fight these injustices (critical motivation), and taking action to enact sociopolitical change (critical action). However, little is known about how each dimension of critical consciousness affects mental health in adolescents of color. In a sample of 367 ethnically and racially diverse American adolescents of color (age range = 13-17; 68.9% girls, 28.6% boys, and 2.5% gender minority; 84.4% US-born), we conducted multivariate regressions in Mplus to examine the cross-sectional links between each critical consciousness dimension (reflection, motivation, and action) and mental health outcomes (anxiety, depression, and stress) over and above the impact of everyday discrimination. We also investigated the interaction between critical consciousness and discrimination in predicting mental health outcomes. Controlling for age, gender, nativity, and social class, we found that discrimination and critical action were both positively associated with anxiety, depression, and stress. For our covariates, girls and gender minority adolescents reported worse outcomes. No interactions were significant. Overall, critical action, while necessary to enact societal change, may have a complex relationship with youth's depression, anxiety, and psychological stress symptoms and warrants careful exploration. Future research should focus on understanding the longitudinal mechanisms of critical action and how we can maximize the benefits by protecting youth from those negative effects.
