To estimate participants’ daily eating habits
Type of Measure
Created for study
Using a 5-point response scale, participants rate the frequencies with which they typically engage in five different types of diet-related behaviors:
- Eating breakfast
- Eating between meals
- Taking vitamin supplements
- Consuming fruits
- Consuming vegetables
Number of Items
For eating breakfast and eating between meals:
0 =not in past year, 1 = less than once a month, 2 = once a month or more, 3 = once a week or more, 4 = daily or almost daily
For taking vitamin supplements:
0 = less than once a month, 1 = once a week, 2 = 2 or 3 times a week, 3 = once a day, 4 = more than once a day
For fruit and vegetable intakes:
0 = less than once a week, 1 = once a week, 2 = 2 or 3 times a week, 3 = 4 or 5 times a week, 4 = once a day, 5 = more than once a day
The diet score used in Cohen et al. (1991) was created by taking the sum across the breakfast, fruit, and vegetable items. Because of the difference in scale between the former and latter 2 items, the breakfast variable was multiplied by 1.25 prior to computation.

Type of Measure
Revised. The CLUE II FFQ is 62-item modification of the Block Health Habits and History Food Frequency Questionnaire.
Participants used the CLUE II FFQ to report on their usual eating habits over the past year. The FFQ is comprised of a checklist of several types of foods and beverages. For each food/beverage item, respondents are asked to report both their typical frequency of consumption during the past year, and their usual portion size. Frequency is rated on a 9-point scale, ranging from never/less than once a month to two or more times per day. Portion sizes are rated as being small, medium, -or large relative to a provided example of a medium serving. Calculations for nutrient intake can be estimated via computerized software programs that multiply the reported frequency of each food by the amount of nutrient in a serving of that food. Computer editing and nutrient analyses of PCS1 and PCS2 FFQ data were performed by Block Dietary Data Systems (Berkeley, CA). Nutrient analyses now are performed by NutritionQuest.
