| contents | This study applies the Causal Fairness Analysis (CFA) framework of Plecko and Bareinboim (2024) to decompose the total variation in STEM outcomes attributable to ADHD status into direct, indirect, and spurious components using Pearl's Structural Causal Model. Drawing on nationally representative data from the High School Longitudinal Study of 2009, this study examines two outcomes: cumulative STEM GPA and science identity. Total variation decomposition reveals a statistically significant ADHD penalty on STEM GPA (TV = -0.670), of which 63.3% is attributable to the direct effect (x-DE), indicating that the majority of the disparity operates through pathways not mediated by observed sociodemographic or academic confounders. In contrast, the effect on science identity is small and non-significant (TV = -0.068). Counterfactual direct effect analysis using the one-step debiased estimator further reveals that the direct effect is structured by race, with notable variation across racial and ethnic subgroups. Sensitivity analyses confirm robustness to moderate unmeasured confounding. These findings advance the understanding of ADHD-related inequities in STEM education and highlight the need for fairness-aware policies that address both direct institutional barriers and their differential impact across intersecting social identities. |
