N = 177 Comparison of the domains’ relative impact
% explained variance of intention p-value

Attitude 49 45 .76
Subjective social norm 31 21 .51
Perceived behaviour control 63 50 .25
  1. The table illustrates the predictive power of single domains separately for the study groups. P values for differences between the percentages of explained variance as drawn from regression analyses were calculated using Fishers Z-test.
