Ahn, Song, Moon, Kim, and Lee: The Perception of Laymen and Experts Toward Mobile Applications for Self-monitoring of Diet Based on in-depth Interviews and Focus Group Interviews



We conducted a qualitative study to explore the feasibility of mobile applications for self-monitoring of diet.


We conducted in-depth and focus group interviews with eight laymen who had used mobile dietary applications and eight experts. Interviews were audio-recorded and analyzed using an open coding method.


The qualitative data of our study revealed two key themes: (1) perceptions, opinions and attitudes towards mobile applications of self-monitoring of diet and (2) future directions to improve mobile applications.


Our qualitative study suggested the potential use of mobile applications as a food-tracking and dietary monitoring tool and the need for improved mobile applications for self-monitoring of diet. The results of our study may provide insights into how to technically improve mobile applications for self-monitoring of diet, how to utilize dietary data generated through mobile applications, and how to improve individual's health though mobile applications.
