Scientific title | A brief and early psychological intervention for individuals exposed to psychological trauma |
Study objectives | A time by group interaction is expected whereby self-reported symptoms of posttraumatic stress disorder (PTSD) will be less severe in the intervention group than in the no intervention control group at the post-test, but not at the pre-test or at mid-treatment. |
Ethics approval(s) | McGill's Research and Ethic Board. Date of approval: 09/09/2002 (protocol number: A01-B03-02A) |
Health condition(s) or problem(s) studied | Posttraumatic stress disorder |
Intervention | This is a single-blind, randomised controlled trial with a treated group and another group on a waiting list completing the periodic assessments only. This two-session dyadic intervention includes elements of psychoeducation and motivational interviewing, and targets communication between the patient and significant other, aiming to facilitate support, promote bi-directional disclosure, reduce disclosure-constraining behaviours, and improve coping. It promotes the disclosure of thoughts and emotions about the trauma in the natural environment of the dyad while attempting to reduce social constraints on disclosure and negative social support interactions. The intervention is led by a social worker or a nurse trained and supervised every second week by a clinical psychologist. The initial 90-minute session takes place within the first few weeks after the traumatic event. A 75-minute follow-up meeting is scheduled two weeks later. |

Primary outcome measure | PTSD self-reported symptoms as measured by the Impact of Event Scale Revised. We measured PTSD symptoms on average 26 days after trauma exposure (baseline, before treatment), then on average 40 days post-trauma at mid-treatment (after one treatment session), and 90 days after trauma exposure (a time when one can diagnose chronic PTSD), and then again 2 years after trauma exposure. |
Secondary outcome measures | Negative social support. (It was hypothesised that the treatment would decrease the provision of negative social support from the significant other toward the trauma victim.). This was assessed using the Social Constraints Scale (SCS). Timepoints: 26 days (on average) after trauma exposure (baseline, before treatment), 40 days post-trauma at mid-treatment (after one treatment session), 90 days and 2 years after trauma exposure. |
