| Popis: | 105 With increasing rates of overweight and obesity, public health researchers are engaging in developing innovative method by new technology to help people to achieve healthy weights. Mobile technology and health promotion apps provide a good opportunity to collect and deliver people''s individualized health information as well as real-time assessment, tailored feedback, and advice at the appropriate time to improve self-management and health behavior change over time. A growing trend for the use of mobile technology and mHealth has attracted the attention of practitioners, researchers and policymakers globally. Despite that health-related apps are relatively effective tools in health self-management interventions, a better understanding of what factors determine individuals to use such health-related apps are still limited. Theory plays a critical role in public health interventions and research. Previous studies adopted the Technology Acceptance Model (TAM) or Technology Readiness Acceptance Model (TRAM) independently to explain people''s intention to use the mhealth apps and without taking into account people''s cognition factor, health consciousness. This study proposed an extended research framework of TRAM which includes an individual’s health consciousness to fill the gap of previous studies and to improve the prediction power of an individual''s usage intention of the dietary and fitness apps. A total of 994 participants who completed self-reported online questionnaire surveys in Taiwan. The results of structural equation modeling (SEM) indicated that the prediction power of the proposed extended TRAM model which includes health consciousness has better prediction power than that of the original TRAM model. The drivers of an individual''s technology readiness, optimism and innovativeness, have positive impacts on his or her perceived ease of using the dietary and fitness apps. An individual''s optimism also has positive impact on his or her perceived usefulness of using the dietary and fitness apps. One of the inhibitors of an individual''s technology readiness, discomfort, has negative impact on his or her perceived ease of using the dietary and fitness apps. The components of TAM model, an individual''s perceived ease of usefulness of using the dietary and fitness apps, has positive contributions on his or her attitude toward using the dietary and fitness apps, which in turn has positive contribution to his or her intention to use the dietary and fitness apps. Based on the study results, this study can provide some managerial implications and suggestions for the public health sector, the dietary and fitness developers and the promotion marketers. |
