Psychomotor retardation and externally oriented thinking in major depression

Area of Science:

• Psychiatry
• Clinical Psychology
• Affective Disorders

Background:

• Alexithymia, characterized by difficulty identifying and describing emotions, is often observed in psychiatric conditions.
• Depression is a prevalent mood disorder with diverse symptom presentations.
• Understanding the relationship between alexithymia and depression is crucial for effective diagnosis and treatment.

Purpose of the Study:

• To explore correlations between alexithymia and depressive states.
• To examine relationships using specific subscales of the Toronto Alexithymia Scale (TAS-20) and the Hamilton Rating Scale for Depression (HAM-D).

Main Methods:

• Assessed 75 patients with Unipolar Depression and 63 controls using the HAM-D and TAS-20.
• Divided participants into age subgroups (30-60 and 61-80 years).
• Investigated correlations between alexithymia and depressive symptoms globally and by subscale.

Main Results:

• Positive correlations found between HAM-D and TAS-20 total scores in patients.
• HAM-D psychomotor retardation correlated with TAS-20 total score and subscales in patients, particularly females and those aged 30-60.
• Anxiety/somatization correlated with TAS-20 in the control group.

Conclusions:

• Confirmed the link between alexithymia and affective symptoms in both patients and controls.
• Highlighted the correlation between psychomotor retardation and externally oriented thinking in patients.
• Suggested cognitive theories may explain how externally oriented thinking contributes to psychomotor retardation in depression.
