Latent categories analysis of postnatal post-traumatic stress disorder symptom profiles

Aim: To explorelatent categories of postpartum post-traumatic stress disorder (PP-PTSD) symptom profiles and to analyse differences in the demographic characteristics of the various categories of mothers. Methods: From August 2021 to April 2022, a questionnaire survey was conducted using the Urban Birth Trauma Scale and the General Information Questionnaire among women in the obstetric wards, outpatient clinics and pelvic floor muscle rehabilitation centre of a tertiary hospital in Zunyi, China to analyse thelatent categories of PP-PTSD symptom profiles. A questionnaire survey was conducted to explore thelatent categories of PP-PTSD symptoms and to explore the factors influencing thelatent categories through univariate analysis and multiple logistic regression. Results: A total of 243 mothers were included, and PP-PTSD symptoms were classified into 3latent categories (P < 0.05), namely "high PP-PTSD symptoms group" (28.4%), "labour-related symptoms group" (40.3%), and "low PP-PTSD symptoms group" (40.3%), The "group with low prevalence of PP-PTSD symptoms" (31.3%). The mode of this delivery, the number of deliveries, and the month after delivery were the main influencing factors for the classification of PP-PTSD symptom profile. Conclusions: There was heterogeneity and stage in the symptom profile of PP-PTSD, which was divided into 3latent categories. This suggests that health care professionals should pay attention to the heterogeneity and stages of PP-PTSD symptom profiles and provide specific symptom management for different categories of women.
