Multi-Ethnic Study of Atherosclerosis (MESA), 2000, Neighborhood Section

Availability:

Publicly available

Description:

The Perceived Availability of Healthy Foods Scale from the Multi-Ethnic Study of Atherosclerosis (MESA) is a three-item, interviewer-administered scale that measures the quality and availability of fresh fruit and vegetables and low-fat products in the local neighborhood. Higher mean scores indicate greater availability of healthy foods in the neighborhood (i.e., low-fat products, fruits, and vegetables).

Protocol:

The respondents are asked to think of their neighborhood as the area within a 20‑minute walk (approximately 1 mile) from their home and then to indicate the extent to which they agree with the following statements:

1. The fresh fruits and vegetables in my neighborhood are of high quality.

[ ] 1 strongly agree

[ ] 2 agree

[ ] 3 neither agree nor disagree

[ ] 4 disagree

[ ] 5 strongly disagree

2. A large selection of fresh fruits and vegetables is available in my neighborhood.

[ ] 1 strongly agree

[ ] 2 agree

[ ] 3 neither agree nor disagree

[ ] 4 disagree

[ ] 5 strongly disagree

3. A large selection of low-fat products is available in my neighborhood.

[ ] 1 strongly agree

[ ] 2 agree

[ ] 3 neither agree nor disagree

[ ] 4 disagree

[ ] 5 strongly disagree

Scoring Instructions

The Perceived Availability of Healthy Foods Scale is estimated by taking the average across the three items (note that only respondents with complete information for all three items can be assigned a scale score).

Lower mean scores indicate better availability of healthy foods (i.e., low-fat products, fruits, and vegetables).

Note that in papers by Moore, Diez Roux, and Brines (2008) and Moore et al. (2008), the five-point Likert scale was reported as follows: 0 = strongly agree; 1 = agree; 2 = neither agree nor disagree; 3 = disagree; and 4 = strongly disagree.

Personnel and Training Required

No specific training is needed if data are collected through a self-administered questionnaire. If interviewers administer the questionnaire, the interviewer must be trained to conduct personal interviews with individuals from the general population and found competent to administer these particular questions (i.e., tested by an expert) at the completion of this training. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.

Equipment Needs

These questions can be administered in a computerized or noncomputerized format (i.e., paper-and pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer or handheld computer to administer or to allow the respondent to self-administer a computer-assisted questionnaire.

Requirements

Requirement CategoryRequired
Average time of greater than 15 minutes in an unaffected individualNo

Mode of Administration

Self-administered

Life Stage:

Adult

Specific Instructions:

Although used in the context of a personal interview, the questions and response categories are straightforward and can be adapted to a self-administered format.

Definition

This measure utilizes a questionnaire to assess a respondent’s access to healthy foods and healthy eating alternatives in his or her local neighborhood.

Purpose

Obesity and being overweight are major public health issues, and it is well established that obesity is associated with a wide range of serious health outcomes, such as coronary heart disease, cancer, and diabetes. Until quite recently, food purchasing behavior and diet have been regarded purely as matters of individual free choice, and most intervention studies have targeted changing individual behavior (e.g., encouraging healthy eating). This perspective neglects social and material contexts in which food purchasing and diet decisions are made (Diez Roux, 1998). There is now considerable interest in the role of the built and social environments in promoting obesity and being overweight (Egger & Swinburn, 1997; Walker et al., 1999; Davison & Birth, 2000).

Selection Rationale

The protocol was selected because it is low burden, has good reported psychometric properties (Mujahid et al., 2007), and has been shown to be associated with higher-burden measures derived from secondary data and Geographic Information System (GIS) characterizations of the local food environments (Moore, Diez Roux, & Brines, 2008).
