The purpose of this feasibility study was to assist limited English proficiency women predominately from Mexico (N = 24) to lose weight postpartum and establish effect sizes to power a randomized controlled pilot study. At 3 months, a small (0.20) effect size was noted in the experimental group compared to the control group in exercise, stress, and both the subscales of the eating self-efficacy scales. There was a medium (0.50) effect size noted in the experimental group compared to the control group in body mass index (BMI), nutrition, and exercise self-efficacy. There was a large (0.80) effect size noted in the experimental group compared to the control group in subscapular skinfolds and health responsibility.
