Posttraumatic stress disorder symptomatology in the course of allogeneic HSCT: a prospective study

Purpose Despite the life-threatening character of allogeneic hematopoietic stem cell transplantation (allogeneic HSCT), very few longitudinal research exists on posttraumatic stress disorder (PTSD) symptomatology in this patient group. We investigated prevalence, temporal course and predictors of PTSD symptomatology in this population. Methods Patients were assessed before conditioning (T0), 100 days (T1), and 12 months after HSCT (T2). PTSD symptomatology was measured with the PTSD Checklist—Civilian Version. We conducted multilevel modeling and multiple regression analyses. Results Two hundred thirty-nine patients participated at baseline, 150 at T1, and 102 at T2. Up to 15 % met the criteria for PTSD at least once during the course of assessment. Fifty-two percent showed diagnostic relevant levels of intrusion, 30 % of avoidance, and 33 % of arousal at least once. Apart from arousal, which increased between T0 and T1 ( γ = 0.56, p = 0.03), no other severity score significantly differed between time points. Being impaired by pain ( γ = 2.89, p
