“The ISTSS PTSD Prevention and treatment guidelines. Methodology and Recommendations and Position papers on Complex PTSD” have been published with the evidence summaries that generated the recommendations. The guidelines were finalized in October 2018.
The recommendations are based on a systematic review of RCTs, conducting also metanalysis, using the approach of the Australian center for post-traumatic mental health, the Cochrane review, the NICE and the World Health Organization.
High quality systematic reviews developed through the Cochrane collaboration, NICE and the WHO and RCTs from these reviews were used as the basis of the evidence. These were the criteria considered, revaluated and agreed for the ISTSS treatment guidelines.
5.500 potential studies were identified, plus those included in existing systematic reviews. The purpose was to see which interventions were effective in reducing symptoms of PTSD, RCTSs, effect size, early interventions, individual, group and couple interventions, etc.
EMDR had a strong recommendation for the treatment of children and adolescents and for adults with PTSD. A strong recommendation means that interventions with a reasonable quality of evidence and the highest certainty of effect are available.
