Brief summary

A total of 67 people were recruited from maternity units and social media to take part in the study. They first completed an online questionnaire, then filled out the CityBiTS measure, and finally took part in a diagnostic interview over the phone. The CityBiTS scores were compared to the results of the interviews using ROC curve analysis. We looked at how well the scores identified cases (sensitivity), correctly identified non-cases (specificity), and overall accuracy to find the best cutoff scores and see how these compared to other available methods.

Interventions

DIAGNOSTIC_TESTDiagnostic interview

SCID-5 Clinician Version (SCID-5-CV) was used as gold standard method for determining if diagnostic criteria of PTSD was met or not (First, 2023). SCID-5-CV has been validated for use via telephone with good results for PTSD (Osorio et al., 2019). Only the PTSD-chapter was used, and exclusively birth-related traumatic experiences were considered. This was done achieved by adding a question to the interview guide, addressing potentially traumatic experiences associated with healthcare during a physical examination, operation, intensive care or childbirth.
