Abstract—In terms of mobile apps, mHealth technology might enhance public health. However, despite the development of hundreds of health-related mobile applications, few studies have studied their relationship to psychological constructs. This study aimed to evaluate the association between the intensity of mHealth app use and nutrition knowledge, healthy-eating self-efficacy, and positive body image among Jordanian students and to measure their levels. In the first semester of the academic year 2022-2023, a structured, self-administered web-based questionnaire containing valid and reliable measures (i.e., positive body image scale, healthy eating self-efficacy, general nutrition knowledge questionnaire, and the adopted intensity use of mHealth apps scale) was administered to 414 undergraduates. The findings reported that their usage of mHealth-related mobile applications was low, as they had inadequate nutrition knowledge, low healthy-eating self-efficacy, and a moderate positive body image. The Pearson correlation analysis revealed a significant and positive correlation between the degree of usage of health-related mobile applications and nutrition knowledge, healthy eating self-efficacy, and positive body image (p<0.01). These findings underscore the need to promote healthy eating self-efficacy and positive body image among students and to improve their nutrition knowledge. In addition, these results advise decision-makers to encourage students to include mHealth applications in their daily routines to benefit their health.
