However, fostering a sense of social identity has been shown to protect psychological wellbeing and mental health during life transitions, such as entering parenthood. This study therefore investigated the relationship between traumatic childbirth and first-time mothers\u2019 social identity and their psychological wellbeing, and more specifically whether strength of identity as a first-time mother protected psychological wellbeing following traumatic childbirth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Women over the age of 18 who were living in the UK and had given birth to their first child in the past nine months were recruited to the study from clinical and community settings. They completed digital self-report questionnaires about their birth experience, social identity, mental health, and psychological wellbeing. Women who perceived themselves to have had a traumatic birth (the trauma group;<jats:italic>N<\/jats:italic>\u2009=\u200984) were compared to women who did not perceive themselves to have had a traumatic birth (the control group,<jats:italic>N<\/jats:italic>\u2009=\u200939). T-tests and chi square tests assessed preliminary group differences before multivariate analyses of covariance controlled for covariates. Post-hoc tests identified the direction of differences. Multiple regression and moderation analyses analysed interaction effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The trauma group had significantly lower psychological wellbeing (mean\u2009=\u200941.5, 95% CI [39.4\u201343.7],<jats:italic>p<\/jats:italic>\u2009=\u2009.008, partial \u03b7<jats:sup>2<\/jats:sup>\u2009=\u20090.059), compared to the control group (mean\u2009=\u200948.4, 95% CI [45.3\u201351.5]), but the two groups did not differ in the strength of their first-time mother identity, which was high across both groups. Strength of identity did not moderate the relationship between traumatic childbirth and psychological wellbeing. Giving birth by caesarean section independently reduced the strength of the first-time mother identity (<jats:italic>p<\/jats:italic>\u2009=\u2009.017, partial \u03b7<jats:sup>2<\/jats:sup>\u2009=\u20090.049). All analyses controlled for emotional and practical support, perceptions of healthcare staff, and mode of birth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Having a traumatic birth was associated with lower psychological wellbeing, and the strength of first-time mother identity does not appear to moderate this relationship. Factors such as mode of birth may be more important. Further research, including longitudinal designs, is needed to understand the relationship between these constructs and identify more effective ways of protecting first-time mothers\u2019 mental health.<\/jats:p><\/jats:sec>","DOI":"10.1186\/s12884-024-06288-3","type":"journal-article","created":{"date-parts":[[2024,6,21]],"date-time":"2024-06-21T13:02:15Z","timestamp":1718974935000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["The relationship between traumatic childbirth and first-time mothers\u2019 social identity and wellbeing: a cross-sectional observational study"],"prefix":"10.1186","volume":"24","author":[{"given":"Shama","family":"El-Salahi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Knowles Bevis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorna","family":"Hogg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,6,21]]},"reference":[{"issue":"3","key":"6288_CR1","doi-asserted-by":"publisher","first-page":"275","DOI":"10.1007\/s10389-016-0783-y","volume":"25","author":"S Abdollahpour","year":"2017","unstructured":"Abdollahpour S, Mousavi SA, Motaghi Z, Keramat A, Khosravi A.
