Severe depression is devastating for those affected and is often associated with significant risk of suicide. Electroconvulsive therapy (ECT) is a highly effective acute treatment for severe depression, but its use and acceptability are limited by cognitive side effects. Of these, retrograde memory loss is most concerning, and can be long-term. The introduction of ultrabrief right unilateral (UBRUL) ECT into clinical practice has been an important step in reducing the risk of memory impairment, but significant deficits still occur. A new form of UBRUL ECT which utilises a Frontoparietal electrode placement represents a further development. Preliminary data suggest that Frontoparietal UBRUL has good efficacy and less cognitive side effects than UBRUL given using the conventional Temporoparietal electrode placement. Designed as a pivotal trial, this protocol will be the first RCT comparing these two forms of ECT, producing the rigorous efficacy and safety data required to change clinical practice/policy. This is a multicentre, parallel group RCT with 1:1 allocation ratio between Frontoparietal (intervention) and Temporoparietal (comparator) forms of UBRUL ECT. Participation will involve receiving randomised acute ECT under blinded conditions during the randomised acute treatment period (typically around 4 weeks), then completion of a 24-week follow-up period which commences after the cessation of all acute ECT. The study protocol aims to provide 12 randomised acute ECT treatments, though the number of treatments (and hence the length of the randomised acute treatment period) can be adjusted by the participant's own treating/admitting psychiatrist according to their clinical judgement.

UBRUL-FP involves ultrabrief right unilateral ECT delivered using a novel frontoparietal montage, where the anterior electrode is shifted frontally to a position above the midpoint of the right eye to avoid temporal lobe stimulation (and reduce memory side effects). UBRUL-FP will be delivered using standard ECT devices.
UBRUL-TP is the standard form of ultrabrief right unilateral ECT, using the conventional temporoparietal (d'Elia) electrode placement, where the anterior electrode is placed over the right temporal lobe. UBRUL-TP will be delivered using standard ECT devices.

Change in Depressive Symptoms as Assessed by Hamilton Rating Scale for Depression-17
The Hamilton Rating Scale for Depression-17 has a range of 0-52. Lower scores represent mild depression to no depression at all.
Time frame: From baseline to end of randomized acute treatment (typically 4 weeks)
Change in Depressive Symptoms as Assessed by Hamilton Rating Scale for Depression-17
The Hamilton Rating Scale for Depression-17 has a range of 0-52. Lower scores represent mild depression to no depression at all.
Time frame: From end of acute ECT treatment up to 24-week follow-up
Autobiographical Memory Interview-Short Form (AMI-SF) Consistency Scores
In the Autobiographical Memory Interview-Short Form, participants are graded on the consistency of their answers between baseline and subsequent time-points. The maximum consistency score is 100 percent, with lower percentages representing increasing inconsistency in retrospective autobiographical memory function.
Time frame: From Baseline to end of randomized acute treatment (typically 4 weeks)
Clinical Global Impression-Severity (CGI-S)
The Clinical Global Impression-Severity measure is a 7-point scale where a clinician rates the severity of a patient's illness in comparison to the clinician's experience with patients who have the same diagnosis. The ratings range from 1 indicating normal, not at all ill to 7 suggesting they are among the most extremely ill patients.
Time frame: From baseline to end of randomized acute treatment (typically 4 weeks)
Clinical Global Impression-Improvement (CGI-I)
The Clinical Global Impression-Improvement is a measure where a clinician assesses how much the patient's illness has improved or worsened in comparison to baseline. The "improved" version being used in this trial (Kadouri, Corruble \& Falissard, 2007) is a 13-point scale with ratings which range from 6 ('ideal improvement') to -6 (maximum deterioration).
Time frame: Through the randomized acute ECT treatment period (typically 4 weeks)
Suicidality score
Assessed by examining scores on item 3 (suicidality) of the Hamilton Rating Scale for Depression (which range from 0 to 4, where higher scores indicate more severe and/or persistent suicidality) and scores on the suicidal ideation subscale of the Columbia
Time frame: From baseline to end of randomized acute treatment (typically 4 weeks)
Post ECT reorientation time
Post ECT reorientation time is the time taken to recover orientation immediately after ECT in randomised treatment phase.
Time frame: After ECT sessions 3 and 6, which typically occur at the end of week 1 and week 2 in the randomised acute treatment phase.
Change in mean neuropsychological function
Assessed by a cognitive test battery.
Time frame: From baseline to end of randomized acute treatment (typically 4 weeks)
Mental Health Questionnaire-14 (MHQ-14)
The Mental Health Questionnaire-14 is a self-report quality of life instrument consisting of the mental health component of the Medical Outcomes Study questionnaire. This patient self-report measure contains 14 items in total, addressing symptoms of fatigue, anxiety and depression, and the impact of these symptoms on functioning. Scores on this measure range from 0 to 100, where higher scores indicate better quality of life.
Time frame: From baseline to end of randomized acute treatment (typically 4 weeks)
Number of responders
Response is defined as a 50 percent reduction in depression severity from baseline, assessed using the Hamilton Rating Scale for Depression-17
Time frame: From baseline to End of Randomized Acute Treatment (typically 4 weeks)
Number of remitters
Remission is defined as a score of ≤ 7 on the Hamilton Rating Scale for Depression-17.
Time frame: From baseline to end of randomized acute treatment (typically 4 weeks)
Number of participants switched from randomized treatment to another form of acute ECT
Number of participants switched from randomized treatment to another form of acute ECT after receiving at least 8 randomized ECT.
Time frame: After at least 8 randomized ECT treatments (typically after 3 weeks).
Number of randomized ECT treatments given over the Acute Study Treatment Phase (RCT)
Number of randomized acute ECT treatments received by participants during the Acute Study Treatment Phase (RCT), compared between the groups.
Time frame: From baseline to End of Randomized Acute Treatment (typically 4 weeks)
Occurrence of adverse events and serious adverse events
Occurrence of adverse events (AEs) and serious adverse events (SAEs) compared between the groups, based on treating them as binary outcomes (no/yes, e.g., whether participants experienced any given side effect/adverse event at least once) and as count outcomes (number of occurrences).
Time frame: From baseline and up to 24-week follow-up
