Abstract

Background and purpose: Several studies have found that women who have experienced
childhood sexual abuse (CSA) have an increased risk of developing Post-Traumatic Stress
Disorder (PTSD) related to their victimization experiences. The current study evaluated the
presence of PTSD symptoms and general psychiatric distress (GSI from SCL-90-R) five years
after discharge among adult women suffering from sequelae from childhood sexual abuse.
Materials and method: This 5-year follow-up study of a randomized controlled trial included
106 women: 52 assigned to analytic group psychotherapy and 54 assigned to systemic group
psychotherapy. PTSD symptoms and general psychiatric distress were evaluated at baseline,
at discharge, 1 year and 5 years after discharge, using the crime-related post-traumatic stress
disorder scale (CR-PTSD) and the Global Severity Index (GSI) from the Symptom Checklist-
90-Revised (SCL-90-R). At the 5 year follow-up, the PTSD Checklist-Civilian (PCL-C) was also
administered to confirm the findings from CR-PTSD and to determine whether the women met
the DSM-IV symptom criteria of PTSD. ANOVA was performed using treatment group as a
between factor and the four time points as repeated measures.
Results: PTSD symptoms and general psychiatric distress were significantly reduced during
therapy for both treatment modalities (P < 0.000), but the systemic group exhibited significantly
more reduction of PTSD symptoms than the analytic group (P < 0.002) at discharge. No
difference in reduction of PTSD symptoms and general psychiatric distress was found
between groups at 1 and 5 year follow-up. Difference in trajectories was found for the two
groups (time*treatment group interaction, CR-PTSD, P = 0.012 and GSI, P = 0.021). Level of
PTSD symptoms on the CR-PTSD was validated at 5 year follow-up by the total symptom
severity score on the PCL-C (r = 0.929). Of the women participating in the 5-years follow-up,
18 (28%) met the DSM-IV symptom criteria as measured by PCL-C (analytic: 36%, systemic:
21%, χ2 NS).
Conclusion: Symptoms of PTSD and general psychiatric distress were reduced in women
with a history of CSA participating in both analytic and systemic specialized incest group
psychotherapy. Improvement was maintained for both groups at 5-year-follow-up. The
trajectories of PTSD symptoms and GSI for the two groups differed significantly, however.
Implications of the difference in trajectories for treatment planning will be discussed. The
findings in the present study stress the importance of long-term follow-up studies in evidencebased reserch.
