TMS in major depression: A retrospective naturalistic study including two subjective tools.

ObjectiveTo report the outcomes of transcranial magnetic stimulation (TMS) treatment of patients with acute major depressive disorder (MDD), with particular attention to the performance of the individual assessment tools, including two new subjective mood scales.MethodsPatients with MDD were treated with up to 35 daily TMS sessions. Objective quantification of mood utilised the Hamilton Depression Rating Scale (HAM-D6) and the Clinical Global Impression-Severity scale (CGI-S). Subjective quantification was made using the Subjective Depression Scale (SDS6) and a new Daily Emotion Score (DES) - a single question which is asked daily.ResultsNinety consecutive patients (58 females; 64.4%) with a mean age of 46.9 years were included. Using HAM-D6 criteria, 51 patients (56.7%) achieved remission. Scores obtained using the different tools correlated well at the same time point, especially at the conclusion of TMS therapy. The only statistically significant independent predictors of remission were the percentage improvement at session 10 (relative to baseline) in the SDS6 ( = .0026) and in the DES ( = .043).ConclusionThe SDS6 was confirmed as a valuable companion for the HAM-D6. The DES correlated with the other subjective tool (SDS6); the latter, in particular, may also have utility in predicting treatment outcome.
