Diurnal variation in depression--is it there?
The Journal of Nervous and Mental Disease
|July 1, 1975
Summary
This study found that most unipolar depression patients reporting diurnal mood variation did not show it in behavioral measures or self-assessment inventories. This suggests mood fluctuations in depression may be distorted or retrospectively falsified.
Area of Science:
- Psychiatry
- Psychology
Background:
- Diurnal variation in mood is often reported by individuals with unipolar depression.
- Quantifying depression depth typically involves psychiatric interviews and rating scales like the Hamilton Rating Scale.
Purpose of the Study:
- To measure diurnal mood variation in unipolar depressives using self-assessment and behavioral measures.
- To compare self-reported mood fluctuations with objective behavioral assessments in depressed patients.
Main Methods:
- Utilized a sensitive self-assessment inventory for mood.
- Employed a behavioral measure to assess the depth of depression.
- Correlated findings with the established Hamilton Rating Scale.
Main Results:
- All patients reported experiencing diurnal mood variations.
- Observed fluctuations were not evident in behavioral measures for most patients.
- Only one patient demonstrated a significant difference on the depressive inventory.
Conclusions:
- Self-reported mood variations in unipolar depression may not align with behavioral observations.
- Perceptual distortion or retrospective falsification might influence self-report accuracy in depression.
- Further research is needed to understand the discrepancy between subjective experience and objective measures of mood variation in depression.
