BACKGROUND AND OBJECTIVES Previous descriptions of the Advanced Life Support in Obstetrics (ALSO) course have indicated increases in physician comfort in managing obstetric emergencies and in their intentions to continue offering maternity care after taking the course. No previous studies have been done about the educational outcomes of the ALSO course on family practice residents. This study compared residents' pre- and post-ALSO course confidence to manage obstetrical emergencies and their intention to provide maternity care when they enter practice. METHODS A self-selected group of 55 family practice residents completed questionnaires before and after ALSO training. The questionnaire was designed to measure confidence, using Bandura's model of self efficacy, and future intention, using Ajzen's Theory of Planned Behavior. RESULTS Residents' confidence in their abilities to manage obstetrical emergencies increased significantly after the ALSO course. Residents' intent to provide maternity care when the residents enter practice did not change. CONCLUSIONS The ALSO course is a valuable teaching intervention that can improve family practice residents' perceived self-confidence in managing obstetric emergencies. The study had sufficient power to detect a moderate effect size of the ALSO course on resident intention to provide maternity care but did not do so.
