The independent predictive value of peritraumatic dissociation for postdisaster intrusions, avoidance reactions, and PTSD symptom severity: a 4-year prospective study.

This 4-year prospective study (N=662) of victims of a fireworks disaster examines the independent predictive value of peritraumatic dissociation for self-reported intrusions, avoidance reactions, and posttraumatic stress disorder (PTSD) symptom severity at both 18-months (T2) and almost 4-years postdisaster (T3). Peritraumatic dissociation was measured 2-3 weeks after the disaster (T1). Hierarchical multiple regression analyses revealed that peritraumatic dissociation was not a strong independent predictor for intrusions and avoidance reactions and PTSD symptom severity at T2 or at T3 above initial intrusions, avoidance reactions, and psychological distress (T1).

Post-disaster mental health problems and the utilization of mental health services: a four-year longitudinal comparative study.

This study examined mental health problems and mental health services (MHS) utilization after a fireworks disaster among adult survivors and a comparison group. The disaster took place on May 13, 2000, in the city of Enschede, The Netherlands. Victims (N=662) participated in a survey 2-3 weeks (T1), 18 months (T2) and 4 years (T3) post-disaster.
