NCI brief Fruit and Vegetable intake survey was used to measure dietary intake. Participants reported the frequency of each specific food eaten over the past 12 months. Values are:1 = never, 2 = less than once per month,3 = 1-3 times per week, 4 = 3-4 times per week,5 = 5-6 times per week, 6 = 1 time per day, 7 = 2 or more times per day. Higher scores indicate more frequent fruit and vegetable intake.There is no minimum or maximum available for this measure.

The frequency reported categorically on the questionnaire was converted to the number of times fruits/vegetables were consumed per day as shown below. In general, the midpoint of the frequency range was used.

Frequency ResponseTimes Per Day Never 0.0 Less than once a month 0.018 1-3 times per month 0.066 1-2 times per week 0.214 3-4 times per week 0.499 5-6 times per week 0.784

The International Physical Activity Questionnaire Short Form (7 items) was be used to measure physical activity. Participants are asked to report frequency (days/week) and duration (hours/ day or minutes/day) of vigorous and moderate physical activities performed in the past 7 days.

Participants were asked about 3 specific types of activity: walking, moderate-intensity activity, and vigorous-intensity activity. Participants also reported frequency (days per week) and duration (time per day) for each specific type of activity. To create metabolic equivalent of task (MET, energy expenditure) measures, we multiplied frequency by duration (in hours). We then used the summation times 3.3 MET (walking), 4.0 (moderate physical activity), and 8.0 (vigorous physical activity) to generate physical activity scores in MET units. Higher scores indicated more energy expenditure.

Autonomous motivation. To measure autonomous motivation, we used the Treatment Self-Regulation Questionnaire (6 items for stress management). Participants rated how true each statement was for them related to stress management using a 7-point scale: 1 (not at all true) to 7 (very true). We summed responses to the 6 items to create a score for stress management. Scores can range from 6 - 42. Higher scores indicated higher autonomous motivation.

Autonomous motivation. To measure autonomous motivation, we used the Treatment Self-Regulation Questionnaire (6 items for healthy eating). Participants rated how true each statement was for them related to healthier eating using a 7-point scale: 1 (not at all true) to 7 (very true). We summed responses to the 6 items to create a score for healthy eating. Scores can range from 6 - 42 Higher scores indicated higher autonomous motivation.

Self-efficacy. We used surveys to measure self-efficacy. We also used the general self-efficacy scale (10 items) to measure self-efficacy. Participants rated the truthfulness of each statement using a 4-point scale: 1 (not at all true) to 4 (exactly true). We summed responses to the 10 items to create a score for general self-efficacy. Scores can range from 10 - 40. Higher scores meant higher self-efficacy.

Self-efficacy. We used surveys to measure self-efficacy for healthy eating (8 items). Participants rated levels of confidence using a 4-point scale: 1 (not at all confident) to 4 (very confident). We summed responses to the 8 items to create a score for self-efficacy for healthy eating. THigher scores meant higher self-efficacy. Participants rated the truthfulness of each statement using a 4-point scale: 1 (not at all true) to 4 (exactly true). We summed responses to the 10 items to create a score for general self-efficacy.

Scores can range from 8 - 32. Higher scores meant higher self-efficacy.

Emotional control. To measure emotional control, we used the Emotion Regulation Questionnaire to assess the emotional regulatory process using reappraisal (6 items) and suppression (4 items). Participants rated the degree of agreement using a 7-point scale: 1 (strongly disagree) to 7 (strongly agree). The suppression items were reverse coded prior to score computation. We summed responses to the 10 items to create a score for emotional control. Scores could range between 10 - 70. Higher scores meant better emotional control.

We used the Perceived Stress Scale (10 items) to measure stress. Participants rated the frequency of stressful life situations in the past month using a 4-point scale: 1 (never) to 4 (often). We summed responses to the 10 items to create a score for stress. Scores can range from 10-40. Higher scores meant perceived higher levels of stress.

NCI brief dietary fat intake survey was used to measure dietary fat intake. Participants reported the frequency of each specific food eaten over the past 12 months. Values are:1 = never, 2 = less than once per month,3 = 1-3 times per week, 4 = 3-4 times per week,5 = 5-6 times per week, 6 = 1 time per day, 7 = 2 or more times per day. Higher scores indicate more frequent fat intake.There is no minimum or maximum available for this measure.

The following procedures were used to convert an individual's responses to an estimate of that individual's percentage energy from fat: The frequency reported categorically on the questionnaire was converted to the number of times fat was consumed per day as shown below. In general, the midpoint of the frequency range was used.

Never 0.0 Less than once a month 0.018 1-3 times per month 0.066 1-2 times per week 0.214 3-4 times per week 0.499 5-6 times per week 0.784
