Objectives: In the present study, we investigated the association between the severity of each symptom evaluated by the Montgomery-Asberg Depression Rating Scale (MADRS) at baseline and responsiveness to treatment in patients with major depressive disorder (MDD) to identify the items that predict treatment response.
Methods: The patients received a diagnosis of MDD if they had a score greater than 20 points on the MADRS. Following admission, 120 patients were enrolled in the study, and 89 patients completed the study. For the first week, a 20-mg/d dose of paroxetine was administered; thereafter, the dose was increased to 40mg/d. The MADRS was applied at baseline and after 1, 2, 4, and 6 weeks. We defined responders as patients with improvements in their MADRS scores of more than 50% after 6 weeks of treatment. A multiple regression analysis of MADRS scores at 6 weeks was performed to identify patients who responded to treatment.
Results: There was a significant difference between responders and non-responders in the reported sadness (RS) score for all MADRS items. In the multiple logistic regression analysis, only the RS and concentration difficulties (C) scores showed a significant association with treatment response. Based on the results of chi(2) tests, RS score cutoff values of 2/3 and 3/4 revealed significant differences in the responder rate. None of the cutoff values for the C score revealed significant differences.
Conclusions: The RS score was significantly associated with responsiveness to paroxetine treatment for MDD, with higher RS scores predicting poor responses to treatment.
