A computer-based incentivized food basket choice tool: Presentation and evaluation.

ABSTRACT:

Objective

To develop and evaluate a low-cost computer-based tool to elicit dietary choices in an incentive compatible manner, which can be used on-line or as part of a laboratory study.

Methods

The study was conducted with around 255 adults.
