INTRODUCTION: A growing body of research indicates that disrespect and mistreatment during childbirth (obstetric mistreatment) are widespread globally. These experiences, along with their prevalence, risk factors, and impacts on maternal mental health, are often assessed using METHODS: An online survey was administered to 620 women, assessing sociodemographic and childbirth-related factors, experiences of disrespect and mistreatment during childbirth, postpartum posttraumatic stress symptoms related to childbirth, personality traits, and parenting stress. RESULTS: Exploratory factor analysis identified a 5-factor model with good internal consistency: negative interactions with healthcare providers, separation from the newborn, medical intrusiveness, verbal mistreatment, and pain experience. Confirmatory factor analysis supported this structure, showing positive correlations with perinatal stress (convergent validity) and no association with openness to experience (divergent validity). Higher scores on the DMCQ correlated with increased parenting stress, particularly distress related to the parental role. Women with higher education, low income, and births in Southern Italy reported greater obstetric mistreatment. Risk factors included primiparity, unplanned cesarean, instrumental delivery, episiotomy, anesthesia, labor exceeding 12 h, and delivery complications. DISCUSSION: In conclusion, the Disrespect and Mistreatment during Childbirth Questionnaire is a psychometrically valid tool specifically designed to address obstetric mistreatment in the early years postpartum.
