Hispanic American adults are at high risk for obesity and obesity-related complications, making it essential for primary care providers to address education to improve weight self-efficacy (WSE). The purpose of this quantitative, quasi-experimental quality improvement project was to determine if or to what degree implementation of shared medical appointments (SMAs) including MyPlate weight and lifestyle intervention impacted the three factors of WSE and total body weight among Hispanic adult patients, in a community clinic in the midwestern United States over four weeks. Weight self-efficacy data was measured using the Spanish Three Factor Eating Questionnaire (TFEQ-SP) among seven (N=7) Hispanic adults with a body mass index (BMI) of 25 or greater. The three TFEQ-SP factors measured were emotional eating, uncontrolled eating, and cognitive restraint. Rosenstock’s health belief model, King’s theory of goal attainment, and Bandura’s social learning theory were utilized as a framework for the project. Paired sample t tests were used to analyze the total body weight and the TFEQ-SP factors. A paired t-test showed that there was a statistically significant decrease in total body weight (M= 2.57, SD = 1.20) (t (6) = 5.685, p = 0.001), emotional eating (M = 1.29; SD = 1.11) (t (6) = 3.57, p = 0.022), and uncontrolled eating (M = 4.43; SD = 1.90) (t (6)=6.159, p = 0.001). A statistically significant increase in cognitive restraint was noted (M = 5.14; SD = 2.22) (t (6) =-6.21, p = 0.001). Using SMAs for a primary care weight intervention, among Hispanic adults, may improve WSE and help patients lose weight. Continuing SMAs over an extended period with a larger sample size would increase options for weight loss and should be expanded to the larger population of overweight and obese Hispanic adults.
