SEM Approach for TPB: Application to Digital Health Software and Self-Health Management

摘要

The goal of this research is to investigate the feasibility of Structure Equation Modeling approach for developing a quantitative behavior model grounded on the Theory of Planned Behavior. Data collected from an IRB sanctioned pilot consisting of approximately 500 participants were used to develop the model. The validity of the model is evaluated based on Chi-square, p-value, and RMSEA for statistical power and goodness of fit. The utility of the model is studied through correlation analysis related to user engagement for self-health management. Example association pattern discovered from the analysis was illustrated for its use in digital health software development.
