4Newsletter is coded –0.5 for answer “no” (n = 193) and 0.5 for answer “yes” (n = 74). Values represent point-biserial correlations.
5Gender is coded –0.5 for woman (n = 161) and 0.5 for man (n = 106). Values represent point-biserial correlations.
aIndicates that the bivariate correlation found in Study 2 is significantly different (p < .05) from the bivariate correlation found in Study 1. Comparisons have been made by using Fisher’s r-to-z transformations (z values are indicated in brackets). To be strictly comparable, comparisons involving BCTI variable have been made by taking only the 10 items from the BCTI 10-item version (M = 3.91, SD = 1.85, α = .89).
