Objective: This study examined the incremental clinical utility of parent and teacher reports of ADHD symptomatology and functional impairment in Latino youth, as well as parent and teacher agreement with the final clinical judgment on a diagnostic structured interview. Method: Participants included 70 Latino youth (47 males, 23 females; M age = 8.13 years, SD = 2.51 years) and their parents and teachers; 60 participants were diagnosed with ADHD. Correlations, percent agreement, kappas, and regressions were utilized. Results: Results demonstrated that teachers agreed with the final clinical judgment more often than did parents. Results additionally demonstrated that functional impairment did not statistically significantly improve diagnostic models already including ADHD symptoms; follow-up analyses were run and are discussed. Finally, results demonstrated that teacher reports statistically significantly improved diagnostic models already including parent reports. Conclusion: The current findings suggest the importance of including both parent and teacher reports of both ADHD symptomatology and functional impairment when assessing ADHD in Latino youth
