Interventions

  • Eatwell — BEHAVIORAL
    The Eatwell intervention content is focused on helping participants make healthier grocery shopping decisions, eat at home more often to take advantage of the optimal defaults present there, and learn how to navigate temptation when eating away from home. The intervention itself involves nutrition education, self-regulation, motivation, and household support. In total, it will last 18 months; index participants will attend 12 workshop sessions that are 90 minutes each. Each workshop session will include approximately 12-16 index participants. The first four sessions will be held weekly in Month 1, and subsequent sessions decrease in frequency. Each index participant will have one enrolled household member who will be asked to join four workshop sessions in a support role: sessions 3, 4, 7, and 10. In these four sessions, household members will receive education about WCRF/AIRC recommendations and training in how to provide instrumental and emotional support to index participants.
  • Nutrition Education Control Group — OTHER
    In the control condition, index participants will receive nutrition education in a series of 12 workshop sessions, following the same schedule as participants in the Eatwell condition. All of the content described under the "nutrition education" component of the Eatwell intervention will be provided. The educational material will be delivered with greater detail and with additional in-session activities, as greater time is devoted to education in the control vs. experimental condition. Participants also will receive monthly educational email messages reiterating key ideas from workshops. Specialized content and activities related to self-regulation and motivation will not be provided in the control condition. If an index participant is randomized to the control condition, their designated household member will have no intervention involvement and will only complete assessments.

Study Details

Cancer is a leading cause of death and will affect many people in their lifetimes. Organizations such as the American Cancer Society and the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) have noted that dietary quality is a key factor influencing cancer risk, but most Americans do not meet these dietary guidelines for cancer prevention. The proposed study will enroll adults from the community (n=236 index participants, 236 household members; N = 472) who have low adherence to WCRF/AICR's four dietary guidelines. Participants will be randomized to either nutrition education or the Eatwell intervention. The Eatwell intervention content is focused on helping participants make healthier grocery shopping decisions, eat at home more often to take advantage of the optimal defaults present there, and learn how to navigate temptation when eating away from home. The findings will be relevant not only to the field of cancer prevention, but to the prevention of other diseases for which dietary quality is important.
