When ADHD traits at 2 years were included in the model the overall regression was statistically significant ( r 2 = 0.640, F (2,79) = 68.44, p < 0.001), ADHD traits at age 2 significantly predicted ADHD traits at age 3 (β = 0.798, p < 0.001), and Prohibition scores at age 2 showed a trend-level predictive association to ADHD traits at age 3 (β = 0.035, p = 0.050).No other predictive associations from EF performance at 2 years to 3-year autism and ADHD traits were found.
