Qualitative Evaluation of the Mindful Eating Questionnaire (MEQ) in Pregnant Women
Qualitative Evaluation of the Mindful Eating Questionnaire (MEQ) in Pregnant Women
The Specific Aim of this supplemental project is to evaluate the Mindful Eating Questionnaire (MEQ) to determine if it is a valid instrument for pregnant women. During this project, the MEQ will be qualitatively evaluated in a sample of pregnant women who are similar in age, ethnicity, education, and marital status to the women targeted for recruitment in the parent study. The qualitative evaluation will include a focus group with 10 participants followed by 30 individual cognitive interviews. Comments from the interviews will be summarized and analyzed systematically for each of the 28 questions of the MEQ and the interviewer will use findings from initial interviews to inform subsequent interviews. Content validity will be evaluated based on responses from the focus group and cognitive interviews, and MEQ items will be evaluated for comprehension, retrieval, judgment, and response. Strengths, weaknesses, relevance, comprehensiveness, and interpretations will be reported for each of the MEQ questions. We will also have some of the more traditional validation parameters (the inclusion of other questionnaires) in the study to collect data on convergent and discriminant validity. The resulting publication will provide readers with a thorough report on the utility and appropriateness of using the MEQ to quantify mindful eating in pregnant women.
Pre-pregnancy maternal overweight/obesity and excess weight gain during pregnancy are associated with metabolic abnormalities in mothers and their offspring. Despite guidelines developed by the Institute of Medicine (IOM) for appropriate levels of gestational weight gain, more than 50% of overweight and obese pregnant women exceed the recommended amount of weight gain during pregnancy (CDC 2009). Updated guidelines from the Institute of Medicine (IOM) in 2009 suggest that individualized dietary counseling and regular physical activity are necessary for pregnant women to achieve appropriate levels of gestational weight gain (IOM and NRC 2009), yet few studies have examined weight management in overweight pregnant women and none were successful at increasing adherence to the IOM guidelines (Polley, Wing et al. 2002; Olson, Strawderman et al. 2004; Asbee, Jenkins et al. 2009; Shirazian, Monteith et al. 2010; Phelan, Phipps et al. 2011).
This project is a supplement to a parent study called Expecting Success: Personalized management of body weight during pregnancy (U01 DK094418-01 PIs: Leanne M. Redman, Ph.D. & Corby K. Martin, Ph.D.). The parent study will test the efficacy of two interventions at promoting appropriate levels of weight gain during pregnancy compared to each other and to a usual care control group. Appropriate levels of weight gain during pregnancy will be defined by the 2009 IOM gestational weight gain guidelines (CDC 2009). The two interventions include training on mindfulness surrounding eating, hunger, and satiety; hence, it is logical to test if changes in mindfulness differ between the two intervention groups and the usual care group. Moreover, it is possible that change in mindfulness will be associated with the study's outcome or different levels of gestational weight gain between the usual care group and the two intervention groups. Finally, changes in mindfulness could mediate the effect of the two interventions on gestational weight gain.
Despite the possible importance of mindfulness to the eating behavior and weight management of pregnant women, no measure has been validated to measure mindfulness in pregnant women. The Mindful Eating Questionnaire (MEQ) is a 28-item self-report instrument that measures five domains of mindful eating: disinhibition, awareness, external cues, emotional response, and distraction. Mindful eating refers to an unbiased awareness of sensations surrounding eating and although a preliminary study found the MEQ to be a valid measure of mindful eating in healthy adults, it has not been validated in pregnant women. A valid measure of mindful eating is required when an intervention is used to increase mindful eating in pregnant women and evaluate if the increase results in healthier eating habits and effective weight management. Indeed, effectively measuring mindful eating is central to evaluating: 1) if an intervention had the anticipated effect on mindful eating, 2) if increasing mindful eating resulted in changes to eating habits and body mass, and 3) if changes in mindful eating mediated treatment effects.
Relationship of the supplement to the parent grant: Mindfulness training is effective at helping people manage their eating habits, making mindfulness training a viable strategy to use with special populations who struggle with eating and weight management, including pregnant women. During the parent study, two personal weight-management interventions designed to meet the unique needs of pregnant women will be deployed and mindful eating techniques are part of these interventions. Although a preliminary study found the Mindful Eating Questionnaire (MEQ) to be valid in a convenience sample of generally healthy adults, it is not known if the MEQ is an appropriate and valid instrument for use with pregnant women, and the proposed project will answer this question. If the MEQ is valid for use with pregnant women, it can be used in the parent study, as well as other studies, to determine if the interventions are effectively at training participant to mindfully eat and if changes in mindful eating mediate intervention effects.
