Abstract:
This study evaluated the predictors of site rater performance in major depressive disorder (MDD) clinical trials by analyzing the education level, depression (indication) experience, and specific scale (MADRS) experience of 217 raters. The results showed that raters with greater experience using the MADRS scale demonstrated significantly higher assessment quality, scoring accuracy, and fewer discrepancies compared to expert reviewers, with scale experience emerging as the strongest predictor of rater performance. Indication experience also contributed to improved scoring accuracy and reduced discrepancies, while educational level was less influential. Overall, the findings highlight that scale experience, followed by indication experience, are the most important factors in ensuring high-quality rater performance in MDD trials.
