Development of eHealth-Based Behavior Change Support for Young Adults Using the Nine Principles Framework

Area of Science:

• Behavioral science
• Nutrition research
• Digital health interventions

Background:

• Adherence to healthy eating and dietary recording is crucial in nutrition research.
• Developing effective behavior change support (BCS) programs for randomized control trials (RCTs) presents challenges.

Purpose of the Study:

• To develop and pilot an eHealth BCS program using the Nine Principles framework.
• To enhance adherence to healthy eating and dietary intake recording in young adults within an RCT.

Main Methods:

• Utilized the Nine Principles framework, Theory of Planned Behavior, and qualitative focus group data.
• Developed a 10-week eHealth BCS program delivered via Facebook and text messages.
• Piloted the program with young adults participating in an RCT.

Main Results:

• The eHealth BCS program appeared to support optimal dietary recording.
• The program demonstrated potential in maintaining desired dietary behaviors.
• The intervention showed promise for improving adherence in RCTs.

Conclusions:

• An eHealth BCS program, guided by theory and user-centered design, can enhance adherence in nutrition research.
• Framework-based, digitally delivered interventions may be effective for improving participant compliance in RCTs.
