Scales	Description/scoring methods
Barriers to care [31]	Twenty “yes” (Y = 1) or “no” (N = 0) questions to measure existence of socio-behavioral procedures practices, which prevent effective assimilation in the health care system. Scoring: Responses were summed to a raw score between 0 and 20 points, where 0 indicated effective assimilation into the health care system and 20 indicated ineffective assimilation into the health care system.
Social support [32]	Twenty questions to evaluate awareness of family and friends supporting personal goals to modify patients’ diet. Reponses (response = x) for both family and friends were: “None” (x = 1), “rarely” (x = 2), “a few times” (x = 3), “often” (x = 4), “very often” (x = 5), and “does not apply” (x = 0). Scoring: Responses were summed to a raw score between 0 and 50 points, where 50 indicated a lot of family/friends support for diet change and 0 indicated no support for diet change.
Depression Scale CES-D [33]	Self-reported assessment consisting of five depression indicator questions with response ranges of “Rarely or none of the time (less than one day)” (x = 0), “Some or little of the time (1–2 days)” (x = 1), “Occasionally or moderate amount of time (3–4 days)” (x = 3), and “Most or all of the time (5–7 days)” (x = 3). Scoring: Responses were summed to a raw score between 0 and 15 points, where 0 indicated minor to no depression and 15 indicated severe depression.
Coping [34]	Two questions identifying patients’ means of solving issues and making important life decisions.
Self-esteem [35]	A ten-question survey evaluating overall measure of self-worth. Response (response = x) ranges were “Strongly Agree” (x = 1), “Agree” (x = 2), “Disagree” (x = 3), “Strongly Disagree” (x = 4), and “Refused/Don’t Know” (x = 0). Scoring: Responses were summed to a raw score between 10 and 40 points, where 10 indicated a high self-esteem and 40 indicated a low self-esteem.
Family Health History [36]	A two-question survey evaluating awareness of cancer related health problems in blood relatives. Response ranges were “yes” (points = 2), “no” (points = 1), and “don’t know” (points = 0). Scoring: Responses were summed to a raw score between 0 and 4, where 4 indicated knowledge of cancer in family history and 0 indicated no knowledge of family health history.
Health Behavior Change [37]	A fifteen-question assessment on stress coping & differences in health behavior among cancer survivors. Response (response = x) ranges were “less” (x = 1), “The Same Amount” (x = 2), “More” (x = 3), “Don’t Know” (x = 4), and “Refused” (x = 5). Scoring: Responses were summed to a raw score between 15 and 75 points.
Cancer Worry Scale [38]	An eight-question survey to assess patients’ personal worry about cancer diagnosis. Response (response = x) ranges were “Never or hardly ever” (x = 1), “Sometimes” (x = 2), “Often” (x = 3), and “Always or Almost Always” (x = 4). Scoring: Responses were summed to a raw score between 8 and 32 points, where 8 indicated no worry and 32 indicated high worry.
FACT-G [39]	FACT-G is an instrument with which respondent cancer patients are asked to respond to various health-related items as it applies to their experience within the past 7 days. The tool is composed of a total 27 questions and includes four subscales. Scoring: Subjects were asked to rate each item using a five point Likert-tvpe rating scale, where 1 = “Not at all,” 2 = “A little bit,” 3 = “Somewhat,” 4 = “Quite a bit,” and 5 = “Very much.” The total score for the FACT-G includes summation of the mean score of each of the four subscales; the mean score for each subscale is then calculated by adding each item response score, multiplying the total by seven and dividing by the number of questions answered. The score range for FACT-G is 0–108.
FACT-B (Breast Cancer Functional Assessment of Cancer Therapy Scale) [39]	FACT-B is a tool with which respondent breast cancer patients are asked to respond to various health-related items as it applies to their experience within the past 7 days. The tool is an additional subscale of F ACT-G and reflects experiences of specific importance to breast cancer patients. The FACT-B subscale is composed of ten total questions. Scoring: As in FACT-G, in FACT-B subjects are asked to rate each item using a five point Likert-type rating scale, where 1 = “Not at all,” 2 = “A little bit,” 3 = “Somewhat,” 4 = “Quite a bit,” and 5 = “Very much.” The subscale score for the FACT-B is its mean score; it is calculated by adding each item response score, multiplying the total by ten and dividing by the number of items answered. The Score range for FACT-B Subscale Score is 0–40. The Total FACT-B Score includes summation of its mean plus the Total FACT-G Score which is scored composed by adding the scores of each of the four subscales: Physical Well-Being, Social/Family Well-Being, Emotional Well-being, and Functional Well-Being. The score range for the FACT-B is 0–148.
Self-efficacy [40,41]	The Self Efficacy questionnaire explores how confident patients are; it is comprised of 24 questions which are organized in seven subscale categories. Scoring: For each of the questions, patients are asked to choose the number on the scale that corresponds to the level of confidence with which they can accomplish the tasks regularly at the present time. The scales are presented in a Likert-type approach ranging from “Not at all confident” to “Totally confident.” The total scale score includes summation of scores on all the questions, with lower scores indicating less satisfaction regarding personal confidence level, and higher scores indicating an observed greater confidence level.
IPAQ Short (Last 7 days) [42]	The International Physical Activity Questionnaire (IPAQ) was developed as an instrument for cross-national monitoring of physical activity and inactivity. Scoring: Both the short and long form data were used to estimate total weekly physical activity by weighting the reported minutes per week within each activity category by a MET energy expenditure estimate assigned to each category of activity. MET levels were obtained from the 2000 compendium of physical activities to include moderate-intensity activities between 3 and 6 METs and vigorous-intensity activities as 6 METs. The weighted MET-minutes per week were calculated as duration frequency per week.
PSS-14 (Perceived Stress Scale) [43]	A total of fourteen questions to evaluate self-reported amount of stress. Response (response = x) ranges were “Never” (x = 0), “Almost Never” (x = 1), “Sometimes” (x = 2), “Fairly Often” (x = 3), and “Very Often” (x = 4). Scoring: Reponses were summed to a raw score between 0 and 16 points, where 0 indicated a low amount of personal stress and 16 indicated a high amount of personal stress.
Brief Family Life Questionnaire [44]	A total of twenty questions designed to measure help and support between patient and family. Response (response = x) ranges were “Strongly Disagree” (x = 1), “Disagree” (x = 2), “Agree” (x = 3), and “Strongly Agree” (x = 4). Scoring: Responses were summed to a raw score between 20 and 80 points, where 80 indicated family support and 20 indicated no family support.
Apter Motivational Style Profile [45]	Survey of forty questions indicating level of motivation by personal experience recollection. Response (response = x) ranges were “Never” (x = 1), “Seldom” (x = 2), “Sometimes” (x = 3), “Often” (x = 4), “Very Often” (x = 5), and “Always” (x = 6). Scoring: Responses were summed to a raw score between 40 and 240 points.
Modeling [46,47]	A total of eight ‘yes’ (Y = 1) or ‘no’ (N = 0) questions of self-reported awareness of social support to improve personal diet. Scoring: Responses were summed to a raw score between 0 and 8 points, where 8 indicated strong patient-family role-model relationships and 0 indicated weak patient-family role model relationships.
Stages of Change [46,47]	A total of five ‘yes’ (Y = 1) or ‘no’ (N = 0) questions identify current change, intention to change, or no intention to change in diet. Scoring: Responses were summed to a raw score between 0 and 5 points, where 5 indicated current change of previous diet choices and 0 indicated no intention of changing current diet.
Medication List [48]	Participant’s self-reported medication list. Participants were asked for dose, frequency, duration, and route for each medicine the participant was taking at the time of the interview. Terms chosen for route are from the RxNorm developed at the NLM.
Diet Assessment Tool [49]	1 Fourteen questions were coded to assign ‘1’ to responses in agreement with a Mediterranean Diet, and ‘0’ to other. Scoring: Items were summed up to get a raw score between 0 and 14 points.
Spices Assessment [49]	2 Twelve questions constructed by the project’s team to evaluate consumption of Mediterranean style diet. Scoring: Each question ranges from 1 to 4 score points making for a raw score range of 12–48, where 48 indicated Mediterranean dietary choices and 12 indicated non-Mediterranean dietary choices.
