Note. CI, Confidence interval; LL, Lower limit; UL, Upper limit. SE B, Standard error of unstandardized regression parameter B.
Habitual behavior and predictors ranged from 0 to 4, except for vulnerability, the affective attitudes and the injunctive norm, which ranged from −4 to 4.
Standardized parameters (β) are not displayed due to the non-normal distribution of the outcome variable. R ² = 0.688, F(10, 866) = 188.41, p < .001.
