Does the behavioral "despair" test measure "despair"?
Physiology & Behavior
|January 1, 1986
Summary
The widely used "despair" test for antidepressants may not accurately reflect depression. Animal immobility in the test is linked to environmental knowledge, not "despair," questioning its validity for human depression research.
Area of Science:
- Neuroscience
- Animal Behavior
- Pharmacology
Background:
- The behavioral "despair" test is a common tool for evaluating antidepressant efficacy.
- This test operates under the assumption that immobility in animals signifies desperation.
Purpose of the Study:
- To investigate the underlying causes of immobility in the "despair" test.
- To determine if "despair" or other factors influence animal behavior in this test.
Main Methods:
- Comparison of animal behavior under varied water depths (4, 15, 30 cm).
- Assessment of the role of prior environmental exposure on immobility.
Main Results:
- Animal immobility in dangerous water conditions (15, 30 cm) is influenced by environmental familiarity, not solely "despair."
- Prior knowledge of the environment significantly alters behavioral responses.
Conclusions:
- The "despair" test's methodology may not accurately model the behavioral aspects of human depression.
- The test's results are confounded by factors beyond a state of "despair."
