  1. Standardized loadings and fit indices of the unidimensional confirmatory factor analytic models for the multi-item Intention scales among participants in the cross-validation sample
  2. ASPQ, Adult Smokers Planning to Quit; ASNPQ, Adult Smokers Not Planning to Quit; EV, e-vapor; CFI, comparative fix index; GFI, goodness of fit index; RMSEA, root mean square error of approximation
  3. aTo achieve over-identification, two error variances similar in magnitude were constrained to be equal
  4. bDue to shared item content and to improve model fit, the error covariance between items was freely estimated
