Role of Dysfunctional Attitudes in the Association Between Discrimination and Adolescents' Mental and Physical Health.

Our study is based on Beck's cognitive stress-vulnerability theory of depression and research on (a) disparities in elevated blood pressure between adolescents from minority and majority backgrounds, (b) the effects of perceived everyday discrimination (PED) on depression and elevated blood pressure, and (c) the associations between depression and cardiovascular diseases. The purpose of our study is to integrate Beck's model and the different research lines by examining the associations of the stressor PED and depressive symptoms with blood pressure through the cognitive vulnerability of dysfunctional attitudes in adolescents. In our cross-sectional study, 97 adolescents (40% female) aged 13 to 15 (M = 14.15, SD = .53) who identified as Black (47.5%), white (47.5%), and mixed race (5%) completed self-reports of PED, dysfunctional attitudes, and depressive symptoms and had their blood pressure measured. We used the PROCESS command tool for SPSS to compute OLS regressions and direct, indirect, and total effects of PED, dysfunctional attitudes, and depressive symptoms on blood pressure. As predicted, our analyses revealed that PED predicts dysfunctional attitudes and depressive symptoms, dysfunctional attitudes predict marginally significant depressive symptoms and significantly systolic blood pressure. Our findings highlight the relevance of PED and dysfunctional attitudes for adolescents mental (i.e., depressive symptoms) and physical health (i.e., blood pressure). If this pattern is replicated, systemic interventions to reduce PED and individual interventions to address dysfunctional attitudes in adolescents could be promising to improve both mental (i.e., depressive symptoms) and physical health (i.e., BP).
