Changing Tactics? Optimizing ECT in Difficult-to-treat Depression (ChaT)
Changing Tactics? Optimizing ECT in Difficult-to-treat Depression: A Randomized Trial Comparing Continuation of Right Unilateral ECT and Switching to Bitemporal ECT in Case of Early Non-response During an Acute Course of ECT for Difficult-to-treat Depression
The goal of this randomized controlled trial is to address which treatment strategy (continue right unilateral (RUL) ECT or switch to bitemporal (BT) ECT speeds up recovery and has the least impact on memory function, in case of early non-response during an acute course of ECT for difficult-to-treat depression.
The main questions it aims to answer are:
- Assess the antidepressant efficacy and cognitive impact of the continuation of an ongoing treatment with RUL ECT compared to switching the treatment technique to BT ECT, in patients failing to show an early response to an acute course of ECT for major depression;
- Assess group and subject-specific trajectories of depressive symptom severity and neurocognitive performance during the acute ECT course and up to 3 months post-treatment.
Participants treated with ECT for depression, showing no 'response' (≥50 percent decrease in depressive symptom severity compared to baseline) after 4 treatment sessions, will be randomized to either switch to BT ECT or continue with RUL ECT. Mood and neurocognitive assessments will be performed at baseline, after 4 ECT sessions (before randomization), after 8 ECT sessions, at the end of the acute course and 3 month after the acute course.

Plan to Share Individual Participant Data (IPD)?
IPD Plan Description
Details on methodology are noted in the protocol. Questionnaires will be used as stated in their manuals. Data of assessments (informed consent, answers to questionnaires,...) are documented on paper and entered in a data platform (Redcap). When access is provided, or data is exported (using a certain standard format such as .xls or .cvs) it can be reused by other researchers. All data is provided with a clear nomenclature, referring to the scores of standardized questionnaires,cognitive assessment tools, ECT parameters,...
Further, published articles by the involved researchers will contain all details necessary to reveal context of data collection, collection methodology, analytical and procedural information, etc.
The pseudonymized data can be made available upon request, after permission is granted by the principal investigator and the head researchers.
