small effect, r between ±0.3 and ±0.5 a medium effect and between
±0.5 and +1.0 a large effect (divided into ±0.5 to ±0.7 and ±0.7 to
+1.0). Table 3 also summarizes additional information on the percentage
of missing cells, significant negative correlations and nonsignificant
correlations. Overall, we did not observe a significant
difference in the size of the positive correlation coefficients between
both timeframes (X2(19) = 1.31; p > .05).
