STRAWB2 (Stress and Wellbeing After Childbirth): a randomised controlled trial of targeted self-help materials to prevent post-traumatic stress disorder following childbirth.OBJECTIVES
 Open-label randomised controlled trial, with blinded outcome assessment.



randomised controlled trial
STRAWB2 (Stress and Wellbeing After Childbirth): a randomised controlled trial of targeted self-help materials to prevent post-traumatic stress disorder following childbirth.OBJECTIVES
 To test whether providing psychological self-help materials would significantly lower the incidence of post-traumatic stress disorder (PTSD) at 6-12 weeks postnatally.


 The self-help materials were a leaflet and online film designed to prevent the development of PTSD after trauma exposure through explaining how to manage early psychological responses.

post-traumatic stress disorder
The primary outcome was a composite of diagnostic and subdiagnostic PTSD at 6-12 weeks postnatally using the gold-standard Clinician-Administered PTSD Scale (CAPS-5) interview.



Clinician-Administered PTSD Scale (CAPS-5)
Diagnostic or subdiagnostic PTSD rates at follow-up did not differ between groups who received self-help (26.7%, 65/243) or usual care alone (26.2%, 64/244) (intention-to-treat analysis: RR 1.02, 95% CI 0.68-1.53).
