(1) Background: In Spain, as in other countries, there is an increase in policies and practices focused on the humanization of perinatal care. In this regard, the quality of interpersonal interactions between women and health professionals is one of the main factors, and, apart from other factors, it is influenced by health professionals´ attitudes towards childbirth. The main objective of this study was to determine the attitudes of obstetricians towards the humanization of childbirth and the promotion of a positive childbirth experience. (2) Methods: The psychosocial task force of the Spanish Society of Obstetrics and Gynecology designed a nationwide online survey. The questionnaire on attitudes towards childbirth (CAVE, acronym for “cuestionario de actitudes sobre vivencias y experiencias en el parto”) was used for the assessment. Exploratory and confirmatory factor analyses of the scale were also performed. (3) Results: A total of 384 participants completed the survey. Obstetricians showed a high-quality clinical obstetric performance, but some difficulties in identifying birth-related psychological-trauma risk factors. Some differences according to practice and gender were found in the final score and in areas regarding psychosocial risk, pain, accompaniment, and women´s expectations. (4) Conclusions: In light of the results, it is advisable to launch education initiatives aimed to improve interaction with pregnant women.
