Major depressive disorder (MDD) is a severe and debilitating illness. Despite the available treatments, clinical outcomes remain suboptimal, and hence, it is crucial to identify predictive factors for response. This is a secondary analysis investigating the relationship between treatment preference and response to treatment in the antidepressant incomplete and non-responders with treatment resistant depression (ASCERTAIN-TRD) trial (NCT02977299) comparing three treatment arms aripiprazole augmentation, repetitive transcranial magnetic stimulation (rTMS) augmentation, switching to venlafaxine XR or duloxetine in MDD patients with treatment-resistant depression (TRD) who are currently on ongoing, stable, and adequate antidepressant therapy. Patient treatment preferences were recorded in the study entry. In total, 278 subjects were randomly assigned to one of three treatment groups: aripiprazole ( n = 92), rTMS ( n = 70), or venlafaxine/duloxetine ( n = 98). Of these 278 subjects, 256 (92.1%) had at least one postbaseline Montgomery–Asberg Depression Rating Scale (MADRS) score and a recorded treatment preference and were included in this secondary analysis. In the total population, participants’ preferences did not affect their response to treatment, and the change in MADRS score was similar among patients who received their preferred treatment, had no preference, or received treatment against their preference ( P = 0.49). These results indicate that patient preference is not a significant factor that predisposes to optimal treatment outcomes.
