Brief Summary

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.

Outcome Measures

Primary Outcomes (6)

• Test-Retest Reliability of the Mindful Eating Questionnaire (MEQ)

  Participants were given the Mindful Eating Questionnaire (MEQ) at their screening visit and study visit in an effort to establish test-retest reliability.

  SV and V1; minimum of 24 hours between visits, maximum of 5 months between visits

• To Determine the Internal Validity of Each of the MEQ's Subscales, we Calculated Cronbach's a

  Cronbach's alpha is a measure of internal consistency, that is, how closely related a set of items are as a group. It is considered to be a measure of scale reliability. Alpha coefficients generally range from 0 to 1, with a higher score indicating greater reliability of a scale. However, a "high" value for alpha does not imply that the measure is unidimensional. Technically speaking, Cronbach's alpha is not a statistical test - it is a coefficient of reliability (or consistency).

  V1

• Convergent Validity of the Mindful Eating Questionnaire Compared to the Eating Inventory (EI) Restraint Subscale

  The convergent validity of the Mindful Eating Questionnaire was assessed using the Eating Inventory (EI) subscales (restraint, disinhibition, hunger) by calculating Pearson correlation coefficients. Below are the results for the comparison of the Mindful Eating Questionnaire's subscales to the Eating Inventory restraint subscale. Correlations were run with and without the External Cues subscale (ECS) since it was found not to be internally consistent.

  V1

• Convergent Validity of the Mindful Eating Questionnaire Subscales to the Eating Inventory Disinhibition Subscale

  The convergent validity of the Mindful Eating Questionnaire was assessed using the Eating Inventory subscales by calculating the Pearson correlation coefficients. Below are the results for the comparison of the Mindful Eating Questionnaire's subscales to the Eating Inventory Subscale of Disinhibition. Correlations were run with and without the External Cues subscale since it was found not to be internally consistent.

  V1

• Convergent Validity of the MEQ Subscales Compared to the EI Hunger Subscale

  The convergent validity of the Mindful Eating Questionnaire was assessed using the Eating Inventory subscales of restraint, disinhibition and hunger by calculating the Pearson correlation coefficients. Below are the results for the comparison of the Mindful Eating Questionnaire's subscales to the Eating Inventory Subscale of Hunger. Correlations were run with and without the External Cues subscale since it was found not to be internally consistent.

  V1

• Correlation of the MEQ Subscales to the MAAS

  The convergent validity of the MEQ was also assessed by calculating the pearson correlation between the MEQ subscales and the Mindful Attention Awareness Scale (MAAS). Correlations were run with and without the External Cues subscale since it was found not to be internally consistent. \*\*Indicates correlation significant at the .01 level

Study Arms (1)

All Participants

Participants will be asked to complete the MEQ, the Eating Inventory Questionnaire, The Mindful Attention Awareness Scale (MAAS), and the Neighborhood Environment Walkability Scale (NEWS). Participants will then be asked to sequentially respond to each of the 28 items and the response choices from the MEQ and briefly discuss their reaction to the items and response choices. Finally, participants will either participate in a focus group or an individual cognitive interview, giving them the opportunity to elaborate on their responses to the MEQ. The first 11 participants completed focus groups and the remaining 29 participants completed individual cognitive interviews.
