The overview of the structural equation model based on the extended protective motivation theory. Note: A: Perceived severity, A1–A3: Three dimensions of perceived severity; B: Perceived susceptibility, B1 and B2: Two dimensions of perceived susceptibility; C: Response cost, C1 and C2: Two dimensions of response cost; D: Response efficacy, D1–D3: Three dimensions of response efficacy; E: Self‐efficacy, E1–E3: Three dimensions of self‐efficacy; K: Knowledge of RAT, K1–K4: Four dimensions of knowledge; and e1–e18: Measurement error of each observation variable. The path with two‐way arrows represents the correlation between two variables. The path with a single‐way arrow represents regression analyses. The number on the path represents the standardized correlation or regression coefficient.
