Affective temperaments in clinical practice: a validation study in mood disorders.

Area of Science:

• Psychiatry
• Clinical Psychology
• Mood Disorders Research

Background:

• Assessing affective temperaments is crucial for understanding mood disorders.
• Clinical validation of self-report temperament measures is an ongoing area of research.

Purpose of the Study:

• To examine correlations between clinical validators and temperaments in patients with mood disorders.
• To evaluate the efficacy of the TEMPS-A (Temperament Evaluation of the Memphis, Pisa, and San Diego Autoquestionnaire) in a clinical setting.
• To determine optimal cut-offs for identifying clinically significant temperaments.

Main Methods:

• 123 consecutive patients in a Mood Disorders Program completed the 50-item TEMPS-A.
• Temperaments assessed included cyclothymia, dysthymia, irritable, and hyperthymia.
• Various cut-offs (50%, 75%, dominant temperament) were analyzed using multivariate regression.

Main Results:

• Cyclothymia demonstrated the strongest correlation with clinical validators, followed by dysthymia and hyperthymia.
• Irritable temperament lacked validation in this patient sample.
• A 75% item endorsement cut-off identified clinically important temperaments in less than half of the participants.
• Patients without a temperament at the 75% cut-off showed better prognostic indicators.

Conclusions:

• Affective temperaments are correlated with clinical validators, particularly cyclothymia.
• The 75% TEMPS-A cut-off may serve as a useful definition for abnormal affective temperaments in mood disorders.
• Approximately half of mood disorder patients exhibit abnormal affective temperaments, with those lacking them possessing better prognoses.
