The three numbers in each cell are the correlation coefficients from three different analyses: sample 1 (n = 208), sample 2 (n = 170), and sample 3 (n = 200). Cohen's (25) criteria is indicated as follows: bold numbers with the “+” indicate a large effect size (0.50 or greater), bold numbers without the “+” indicate a medium effect size (0.30 to 0.49), and numbers not in bold indicate a small effect size (0.10 to 0.29). Statistically insignificant values are not included in the table and are represented as “—”.
