Insufficient enrollment - currently revisiting and updating study eligibility criteria - plan to shift the project to focus on the postpartum period

Primary Study Aims:

1. To evaluate the feasibility, acceptability, and preliminary efficacy of a 10-week mindful eating self-help program for women who binge eat during pregnancy. Primary efficacy targets will include measures of mindful eating and binge eating. Secondary efficacy targets will involve measures of body image and well-being.
2. To evaluate the incremental utility of adding use of a companion mindful eating smart phone application for enhancing the acceptability and preliminary efficacy of the program.
3. To gain insights into ways in which this program may be better tailored to the experiences of pregnancy for future program adaptation and refinement.

Research suggests that binge eating during pregnancy may adversely impact maternal-child health and well-being. For example, clinical evidence cites binge eating as a risk factor for increased gestational weight gain, cesarean delivery, giving birth to infants who are large for gestational age (LGA), and is associated with additional maternal susceptibility for cardiometabolic dysregulation and its complications at this critical maturational period . Nevertheless, surprisingly despite the growth in epidemiological investigations of eating disorders during pregnancy, no studies to date have specifically evaluated a behavioral intervention during pregnancy to address binge eating concerns within this population. Therefore, there is significant need to address this gap in order to develop, evaluate, and disseminate evidence-based behavioral interventions for women struggling with binge eating during pregnancy. One growing area of scholarship is implementing self-help approaches as a means of increasing availability to evidence-based behavioral health interventions for individuals who may not otherwise be able to access these treatments. At the same time, interventions that incorporate mindful eating have recently shown promise as an effective intervention for reducing binge eating and overeating in a wide range of clinical and community samples. These interventions most often conducted over a period ranging between 6-20 weeks of varying formats (e.g., group, in-person versus combination with remote support, etc.), and intensities (e.g., weekly versus bi-weekly, etc.), typically introduce participants to the concepts of mindfulness, provide opportunities to engage in mindfulness meditation practices, apply mindfulness skills to the process of eating via eating-related meditations and other similar exercises including appetite awareness training and encourage between-session home practice. The Am I Hungry? Mindful Eating Program for Binge Eating was used as a model for the present study. In the original pilot investigation a sample of women with binge eating disorder engaged in a 10-week group mindful eating-based treatment program. Results indicated significant reductions in binge eating severity and psychological distress by the final assessment period which were sustained at 1-year follow-up. We have adapted this approach in order to evaluate it in a guided self-help format with and without access to a companion smartphone application and among other things to directly assess not only changes in binge eating but also those related to more adaptive eating processes such as mindful and intuitive eating styles.
