# Implementation of a digital behavior change intervention (eCHANGE) for weight loss maintenance support: a service design and technology transfer approach

## TL;DR

This paper discusses how to design and implement a digital tool called eCHANGE to help people maintain weight loss using service design and technology transfer strategies.

## Contribution

The paper introduces a service design and technology transfer approach for implementing digital behavior change interventions.

## Key findings

- A service design approach can guide the implementation of digital interventions from initiation to delivery.
- A technology transfer process can accelerate the transition of research-based innovations to market-ready solutions.

## Abstract

Obesity is a chronic disease, and while weight loss is achievable, long-term weight loss maintenance is difficult and relapse common for people living with obesity. Aiming to meet the need for innovative approaches, digital behavior change interventions show promise in supporting health behavior change to maintain weight after initial weight loss. Implementation of such interventions should however be part of the design and development processes from project initiation to facilitate uptake and impact. Based on the development and implementation process of eCHANGE, an evidence-informed application-based self-management intervention for weight loss maintenance, this manuscript provides suggestions and guidance into; (1) How a service design approach can be used from initiation to implementation of digital interventions, and (2) How a technology transfer process can accelerate implementation of research-based innovation from idea to market.
