Identifying Birth-Related PTSD: Cutoffs for the City Birth Trauma Scale

Identifying Birth-Related PTSD: Cutoffs for the City Birth Trauma Scale

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.

Inclusion Criteria:

• age 18 or more
• who had given birth with a minimum at four weeks prior to completing CityBiTS,
• who had a sufficient level of Swedish to participate.

Exclusion Criteria:

• Cases of stillbirth
