"Gold standard" Birth: Unmet birth expectations and the ought-maternal-self

Unmet birth expectations are strongly associated with poorer maternal mental health, yet the processes underlying this association remain underexplored. This study addresses critical theoretical and empirical gaps by being the first qualitative investigation to recruit women specifically on the basis of unmet birth expectations and to theoretically account for how sociocultural discourses translate into psychological harm. Twenty-one semi-structured interviews were conducted with first-time mothers in the U.K. and analysed using reflexive thematic analysis. Three inductive themes were generated: (1) The Intensive Birthing Expectation Trap; (2) 'Failed' at the First Hurdle of Motherhood; and (3) Disrupted Maternal Identity. Antenatally, women were immersed in messaging which promoted 'natural' vaginal birth. When births diverged from this, women experienced distress rooted in perceived failure, self-blame, and shame. To account for these experiences, the study introduces the concept of intensive birthing ideology, a cultural framework positioning unassisted vaginal birth as maternally optimal, representing an extension of intensive mothering ideology into the birthing context. Through the first application of Self-Discrepancy Theory to childbirth, this study reveals how intensive birthing ideology creates an "ought-maternal-self"- an internalised representation of maternal obligations. This research advances theory by conceptualising intensive birthing ideology and demonstrating how sociocultural narratives generate psychological vulnerability through specific cognitive processes. It further underscores the urgent need for antenatal education reform, and critical reflection on cultural narratives privileging particular birth modes. With immediate relevance to U.K. maternity policy, this research explains how unmet birth expectations disrupt maternal identity and contribute to psychological harm.
