Objectives
To explore the presence of PTSD and the potential correlations between the risk of developing PTSD and the lifetime mood spectrum signs and symptoms, as assessed with the Mood Spectrum Questionnaire Lifetime Version (MOODS-SR), in a sample of survivors of a liquid gas train crash in Italy, in 2009.
Methods
One hundred eleven subjects were assessed with the Structured Clinical Interview for Axis I Disorder (SCID-I), the Mood Spectrum Questionnaire (MOODS-SR) Lifetime version, the Impact of Event Scale-Revised (IES-R), and the Trauma and Loss Spectrum Questionnaire (TALS-SR).
Results
Sixty-six subjects, of the 111 who completed the SCID-I (59.5%), met criteria for PTSD. PTSD patients showed higher comorbidity rates for Generalized Anxiety Disorder (GAD) (p < 0.001), and lifetime and current Major Depressive Disorder (MDD) (p < 0.001) than subjects who did not develop PTSD. Lifetime MOODS-SR ‘Sociability/Extraversion’ factor and the prevalence of lifetime MDD differentiated subjects with from those without PTSD, when a multiple logistic regression analysis was performed.
Conclusions
Although further research is needed, our results show a significant correlation between the risk of developing PTSD and the mood spectrum comorbidity.
