switch rate
The proportion of participants who transition from depression to mania/hypomania during treatment or study period.
Full Definition
Switch rate quantifies the percentage of study participants who experience a transition from a depressive episode to mania or hypomania during a specified time period, typically during antidepressant treatment. This metric is particularly important in bipolar disorder research and trials involving mixed diagnostic populations. Switch rates help assess the safety profile of treatments and guide clinical decision-making regarding mood stabilizer co-therapy. Calculation methods and time windows for assessment should be clearly defined in study protocols.
Usage
Usage note: Specify time window and criteria for defining mood switches; particularly relevant in bipolar populations.
