Abstract
Background: For effective health promotion using health information technology (HIT), it is mandatory that health consumers
have the behavioral intention to measure, store, and manage their own health data. Understanding health consumers intention
and behavior is needed to develop and implement effective and efficient strategies.
Objective: To develop and verify the extended Technology Acceptance Model (TAM) in health care by describing health
consumers behavioral intention of using HIT.
Methods: This study used a cross-sectional descriptive correlational design. We extended TAM by adding more antecedents
and mediating variables to enhance the models explanatory power and to make it more applicable to health consumersbehavioral
intention. Additional antecedents and mediating variables were added to the hypothetical model, based on their theoretical
relevance, from the Health Belief Model and theory of planned behavior, along with the TAM. We undertook structural equation
analysis to examine the specific nature of the relationship involved in understanding consumers use of HIT. Study participants
were 728 members recruited from three Internet health portals in Korea. Data were collected by a Web-based survey using a
structured self-administered questionnaire.
Results: The overall fitness indices for the model developed in this study indicated an acceptable fit of the model. All path
coefficients were statistically significant. This study showed that perceived threat, perceived usefulness, and perceived ease of
use significantly affected health consumers attitude and behavioral intention. Health consumers health status, health belief and
concerns, subjective norm, HIT characteristics, and HIT self-efficacy had a strong indirect impact on attitude and behavioral
intention through the mediators of perceived threat, perceived usefulness, and perceived ease of use.
Conclusions: An extended TAM in the HIT arena was found to be valid to describe health consumers behavioral intention.
We categorized the concepts in the extended TAM into 3 domains: health zone, information zone, and technology zone.
