NCT02694731

Brief Summary

Participants will complete a 5-week smartphone app-based intervention that teaches mindful eating skills. One goal is to determine to what extent participants will enjoy using the app and complete the intervention. The investigators predict that after completing the intervention, participants will report fewer episodes of eating in response to food cravings. The investigators will also measure several other biological and behavioral outcomes.

Outcome Measures

Primary Outcomes (1)

  • Craving indulgence frequency

    Cell phone questionnaires assess frequency with which participants eat in response to food cravings. Cell phone questionnaires assess frequency with which participants eat in response to food cravings. Participants are asked whether they ate in response to a craving in the past hour

    1 month post-intervention

Secondary Outcomes (7)

  • Craving indulgence frequency

    Administered 9 times over the 7 days after the participant completes the intervention (typically 28 days after beginning the study; may be longer if participant takes extra days to complete the intervention)

  • Reward-based Eating Drive (RED)

    1 month post-intervention

  • Reward-based Eating Drive (RED)

    immediate post-intervention (within 7 days of completing the intervention)

  • Palatable Eating Motives Scale, coping subscale

    1 month post-intervention

  • Palatable Eating Motives Scale, coping subscale

    Immediate post-intervention (within 7 days of completing the intervention)

  • +2 more secondary outcomes

  • Overweight or obese (BMI of 25.0 to 39.9 kg/m2)
  • Score at or above the scale midpoint on the Readiness Ruler, a single-item visual analog scale measure of readiness for behavioral change (prompt is, "I have decided to give in to food cravings less")
  • Have and use a smartphone (Android or iOS) with internet access.
  • Report food cravings on most days and a desire to indulge in food cravings less

You may not qualify if:

  • Current diagnosis of anorexia or bulimia
  • In the opinion of an investigator, meets any of the following criteria:
  • Likely to drop out due to expressed ambivalence or lack of interest
  • Likely to be harmed in any way by participating
  • Likely to have provided untruthful answers to the screening questions (based on evidence such as unclear or inconsistent responses when talking to study staff vs. reporting online, or log data showing repeated attempts to "game" the screening questionnaire).
