Development and Implementation of a Tailored Self-assessment Tool in an Internet-based Weight Loss Maintenance Program

摘要

Background: Using the Internet to replicate client/counselor interactions provides a tremendous opportunity to disseminate interventions at relatively low cost per participant. However, there are substantial challenges with this approach. The Weight Loss Maintenance Trial (WLM) compared two long-term weight-maintenance interventions: (1) a personal contact arm and (2) an Internet arm, to a third self-directed control arm. The Internet arm focused on use of an interactive website for support of long-term weight maintenance. This paper describes a highly interactive self-assessment tool developed for use in the WLM trial Internet intervention arm.
