The mediating role of rumination in the alexithymia- -PTSD relation among employees of emergency services – paramedics and emergency call centre operators

Introduction:
The aim of the study was to investigate the relationship between alexithymia, two types of ruminations (intrusive and deliberate) and post-traumatic stress disorder (PTSD) symptoms for two groups of emergency workers working in Poland: paramedics and emergency call centre operators.

Material and methods:
The research project was conducted the Wielkopolskie voivodship in Poland. The participants were paramedics (n = 72; 54 men, 18 women) and dispatchers (n = 66; 35 men, 31 women). The following Polish versions of standardized tools were used: the Impact of Event Scale-Revised (IES-R), Toronto Alexithymia Scale-20 (TAS-20), and the Event Related Rumination Inventory (ERRI).

Results:
Analysis of the correlation with Spearman’s test demonstrated a statistically significant relationship in both groups between the symptoms of PTSD and ruminations and alexithymia and intrusive ruminations. The correlation between intrusive ruminations and PTSD was stronger for the paramedic group. Also, in the paramedic group, ruminations acted as a mediator for the relation of alexithymia and the intensity of post-traumatic stress.

Conclusions:
The results of the study provide some evidence that paramedics present more PTSD symptoms than emergency call centre operators. The important individual features which increase PTSD are emotional-cognitive aspects of mental processing: ruminations and alexithymia. The paramedics’ direct participation in traumatic events is more overloading for them than the indirect participation in traumatic events for dispatchers.
