“…The PTSD diagnosis was established using the Dutch version of the CAPS-IV (Blake et al, 1995; Dutch version: Hovens, Luinge, & Van Minnen, 2005). To measure the severity of PTSD symptoms by self-report, we used the Dutch PTSD Symptom Scale Self Report (PSS-SR) (Foa, Riggs, Dancu, & Rothbaum, 1993; Mol et al, 2005) and the Dutch Impact of Event Scale (IES) (Horowitz, Wilner, & Alvarez, 1979; Van Der Ploeg, Mooren, Kleber, Van Der Velden, & Brom, 2004). Patients’ exposure to traumatic events was identified using a self-report version of the modified Interview for Traumatic Events in Childhood (ITEC) (Lobbestael, Arntz, Harkema-Schouten, & Bernstein, 2009).…”

“…The Dutch IES (Horowitz et al, 1979; Van Der Ploeg et al, 2004) was used to assess post-traumatic stress symptoms during the course of the treatment programme. According to the authors of the Dutch validation study of the Impact of Event Scale – Revised (IES-R), the original IES was more appropriate than the IES-R (Olde, Kleber, Van Der Hart, & Pop, 2006).…”

Background: There is room for improvement regarding the treatment of severe post-traumatic stress disorder (PTSD). Intensifying treatment to increase patient retention is a promising development. Objective: The aim of this study was to determine the effectiveness of an intensive trauma-focused treatment programme over 8 days for individuals suffering from severe PTSD. Method: Treatment was provided for 347 PTSD patients (70% women; mean age = 38.32 years, SD = 11.69) and consisted of daily sessions of prolonged exposure and eye movement desensitization and reprocessing (EMDR) therapy (16 sessions in total), physical activity, and psycho-education. All participants had experienced multiple traumas, including sexual abuse (74.4%), and suffered from multiple comorbidities (e.g. 87.5% had a mood disorder). Suicidal ideation was frequent (73.9%). PTSD symptom severity was assessed by both clinician-rated [Clinician Administered PTSD Scale (CAPS)] and self-report [PTSD Symptom Scale Self Report (PSS-SR) and Impact of Event Scale (IES)] inventories. For a subsample (n = 109), follow-up data at 6 months were available. Results: A significant decline in symptom severity was found (e.g. CAPS intention-to-treat sample Cohen’s d = 1.64). At post-treatment, 82.9% showed a clinically meaningful response and 54.9% a loss of diagnosis. Dropout was very low (2.3%). Conclusions: Intensive trauma-focused treatment programmes including prolonged exposure, EMDR therapy, and physical activity can be effective for patients suffering from severe PTSD and are associated with low dropout rates.

“…The Dutch Impact of Event Scale (IES; Horowitz, Wilner, & Alvarez, 1979; Van Der Ploeg, Mooren, Kleber, Van Der Velden, & Brom, 2004) was used to index the frequency of posttraumatic stress reactions. We used the IES (15-item version) because the authors of the Dutch validation study of the IES-R (revised) recommended the use of the IES rather than the IES-R as the original IES had a better fit compared to the IES-R (Olde, Kleber, Van Der Hart, & Pop, 2006).…”

Background: It is assumed that PTSD patients with a history of childhood sexual abuse benefit less from trauma-focused treatment than those without such a history. Objective: To test whether the presence of a history of childhood sexual abuse has a negative effect on the outcome of intensive trauma-focused PTSD treatment. Method: PTSD patients, 83% of whom suffered from severe PTSD, took part in a therapy programme consisting of 2 × 4 consecutive days of Prolonged Exposure (PE) and EMDR therapy (eight of each). In between sessions, patients participated in sport activities and psycho-education sessions. No prior stabilization phase was implemented. PTSD symptom scores of clinician-administered and self-administered measures were analysed using the data of 165 consecutive patients. Pre-post differences were compared between four trauma groups; patients with a history of childhood sexual abuse before age 12 (CSA), adolescent sexual abuse (ASA; i.e. sexual abuse between 12 and 18 years of age), sexual abuse (SA) at age 18 and over, or no history of sexual abuse (NSA). Results: Large effect sizes were achieved for PTSD symptom reduction for all trauma groups (Cohen’s d = 1.52–2.09). For the Clinical Administered PTSD Scale (CAPS) and the Impact of Event Scale (IES), no differences in treatment outcome were found between the trauma (age) groups. For the PTSD Symptom Scale Self Report (PSS-SR), there were no differences except for one small effect between CSA and NSA. Conclusions: The results do not support the hypothesis that the presence of a history of childhood sexual abuse has a detrimental impact on the outcome of first-line (intensive) trauma-focused treatments for PTSD.

“…The Cronbach's alpha at the three waves was >0.93 for both subscales. Intrusion and avoidance reactions, which are symptoms characteristic for PTSD, were assessed by the Dutch version of the Impact of Event Scale (IES) (Cronbach's alpha at the three waves >0.83) [21][22][23].…”

Health-related quality of life and mental health problems after a disaster: Are chronically ill survivors more vulnerable to health problems?

Studies have shown that the chronically ill are at higher risk for reduced health-related quality of life (HRQL) and for mental health problems. A combination with traumatic events might increase this risk. This longitudinal study among 1216 survivors of a disaster examines whether chronically ill survivors had a different course of HRQL and mental health problems compared to survivors without chronic diseases. HRQL and mental health problems were measured 3 weeks, 18 months and 4 years post-disaster. Data on pre-disaster chronic diseases was obtained from the electronic medical records of general practitioners. Random coefficient analyses showed significant interaction effects for social functioning, bodily pain and emotional role limitations at T2 only. Chronically ill survivors did not consistently have a different course of general health, physical role limitations, and mental health problems. In conclusion, chronic diseases were not an important risk factor for impaired HRQL and mental health problems among survivors.
