All variables ranged from 0 to 4, except for vulnerability, the affective attitudes and the injunctive norm, which ranged from −4 to 4. In parentheses: Quartiles (Q) are displayed due to the non-normal distribution of habitual behavior; Q1 = 25%, Q2 = 50%, Q3 = 75%. ^aExcept for correlations with habitual behavior. These are Spearmen correlations due to the non-normality of habitual behavior. Boldface: significant with p < .001, except for the following: ^b p = .003; ^c p = .015; ^d p = .001; ^e p = .046. Not significant: ^f p = .248.
