ECT Modality and health related quality of life outcomes after ECT for depression

Introduction: Large improvements in health related quality of life (HRQOL) have been shown after a course of ECT for depression. Currently a wide range of ECT treatment modalities exists in clinical practice, however the effect of different types of ECT on HRQOL outcomes has not been studied. Thus, the present study explored the relationship between different types of ECT modalities and HRQOL outcomes. Methods: Data from 355 depressed patients receiving ECT in three clinical hospitals was included. HRQOL was measured at baseline and after ECT, using the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF). ECT modalities given included different combinations of electrode-placements (Right Unilateral, Bitemporal, Bifrontal) and pulse-widths (brief or ultrabrief). The association between type of ECT and HRQOL after ECT was examined by regression analysis, controlling for variables that may affect HRQOL outcomes. Results: HRQOL scores after ECT increased significantly (p
