Official title
Incentives & Motivation for Behavior Change: Survey-embedded Experiments
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In a series of controlled, randomized experiments, we will systematically manipulate exposure to health-related messages and/or survey methods to examine the effects on behavioral intention. There are various strategies used to influence health-related decision making and the effects of health behavior have had mixed results. In particular, incentive-based interventions have often failed to increase healthy behavior. We will examine 1) the role of behavioral motivation to increase sleep or exercise and 2) current levels of sleep or exercise when predicting who is interested in a mock RCT invitation to increase each behavior using financial or social incentives. In addition to the above focus on sleep and exercise, we will also examine another important health behavior: vaccination. Embedded within experiments studying effects of incentives on vaccination decisions, will conduct methodological tests. In particular, we will estimate the effects of using different methods of measuring the study outcome (vaccine intention).
