NCT03314415

Brief Summary

The purpose of this study is to determine whether robotic assistance can help facilitate adherence, engagement, and weight loss in participants enrolled in a behavioral weight loss program. All participants will be enrolled in the same Web-based weight loss program and take part in "robotic assistance sessions" either early or late in the five-week study. These robotic assistance sessions involve speaking one on one with a robot about diet-related progress.

Outcome Measures

Primary Outcomes (1)

  • Weight change

    Primary outcome is weight change during the with-robot and without-robot periods adjusted for week of weight loss.

    5 weeks

Secondary Outcomes (7)

  • Change in self-reported eating behavior

    Baseline, once during with-robot phase, Week 5

  • Change in self-reported food cravings

    Baseline, once during with-robot phase, Week 5

  • Self-reported quality of life

    Baseline, once during with-robot phase, Week 5

  • Participant engagement with the robot

    2 weeks

  • Robot adherence

    2 weeks

  • +2 more secondary outcomes

Study Arms (2)

Early robotic intervention

EXPERIMENTAL

Participants randomized to the early robotic intervention will attend robotic assistance sessions for a two-week period earlier in the study (during the first half of the study, approximately). Each participant will attend ten 15-minute robotic assistance sessions to interact with a robot (Aldebaraan Nao H25).

Device: Aldebaraan Nao H25

Late robotic intervention

EXPERIMENTAL

Participants randomized to the late robotic intervention will attend robotic assistance sessions for a two-week period later in the study (during the latter half of the study, approximately). Each participant will attend ten 15-minute robotic assistance sessions to interact with a robot (Aldebaraan Nao H25).

Device: Aldebaraan Nao H25

Interventions

The Aldebaraan Nao H25 is a humanoid robot with the capability to interact with people through small movements, gestures, and speech. It does not physically touch the participant at any time.

Eligibility Criteria

Age25 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Men and women who are overweight or obese (body mass index of 25-40 kg/m2)
  • Want to lose weight and enroll in the study, and are willing to sign the informed consent form
  • Able to meet the study requirements for food habits and able to attend online videoconference sessions
  • Willing and able to attend in-person robotic assistance sessions, and are not planning to be out of town for more than five days during the study

You may not qualify if:

  • Self-reported serious food allergies/intolerances, dietary patterns, or active health conditions (e.g., irritable bowel syndrome, Crohn's disease, celiac disease) that would prevent consumption of recommended foods.
  • Concurrent participation in another weight loss program or \>2 hours/day of exercise on average.
  • Actively dieting or self-reported weight loss of \>10 lb in the past 3 months
  • Vulnerable populations, including women who are pregnant and adults who are unable to consent
  • Women who are lactating or planning to become pregnant within two months of the start date, per self-report
  • Diagnosis of a serious mental health condition
  • Non-English speaking individuals
  • Medical complications or chronic illness that would prevent full participation (e.g., active cancer)
  • Surgical procedures that influence hunger or satiety (e.g., gastric bypass, bowel rerouting, stomach sleeve)
  • Primary training as a Clinical Nutritionist or practicing Registered Dietitian
  • Diagnosed eating disorder
