*p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001; r = Pearson product moment correlation coefficient; Beta = standardised regression coefficients. 1 The two blocks in the TPB reflect the two different regression analyses that were run to predict behavioural simulation, one with all the theoretical constructs from the model, and one with only the proximal predictors of behaviour (Intention, PBC). Both direct and indirect measures of PBC and attitude (TPB) were included in this study as each have been used to measure these constructs in the literature. However, only the indirect, theoretically derived measures were included in these theoretical regression equations Similarly, Generalised Self Efficacy was included in this study because this is how some studies using SCT have interpreted and operationalised SE, however only the theoretical measure of SE is included in this theoretical regression equation.
