Posttraumatic Stress and Alexithymia: Symptom Associations

Area of Science:

• Psychology
• Trauma Studies
• Mental Health Research

Background:

• Alexithymia and posttraumatic stress disorder (PTSD) share a known association.
• Previous research primarily focused on male populations in high-risk occupations.
• Limited understanding exists regarding these associations in female populations.

Purpose of the Study:

• To investigate the relationship between posttraumatic stress (PTS) and alexithymia in female university students.
• To explore potential sex differences in the association between PTS and alexithymia.

Main Methods:

• 100 trauma-exposed female university students participated.
• Utilized the Life Events Checklist, PTSD Checklist for DSM-5 (PCL-5), and Toronto Alexithymia Scale (TAS-20).
• Employed multiple regression analyses to examine associations between alexithymia and PCL-5 subscales.

Main Results:

• Total alexithymia scores (TAS-20) were significantly associated with total PTS scores (PCL-5).
• Difficulty in Identifying Feelings (DIF) subscale showed a strong positive association with most PCL-5 subscales.
• Sex differences emerged, with DIF being most strongly linked to PTS in women, unlike males where describing feelings is more associated.

Conclusions:

• The findings support the universality of the association between alexithymia and PTS.
• Highlights significant sex differences in how alexithymia facets relate to PTS, particularly the role of DIF in women.
• Suggests clinical implications for understanding and treating trauma-related stress in women.
