Behavioural despair assessments are standardised paradigms in which brief, inescapable stress is used to elicit immobility, which is quantified as an index of passive coping. The forced swim test places a rodent in a cylinder of water from which it cannot escape and scores active swimming and climbing against passive immobility during a five-minute test that follows a longer pre-test exposure [1]. The tail suspension test suspends a mouse by the tail and records the duration of the immobile posture [2]. Reduced immobility is read as an antidepressant-like effect, provided that general locomotor activity is unchanged [1]. Construct and face validity for depressive-like states are weak, and immobility is held to reflect stress-coping strategy rather than depression [3].
