A Chi-square test confirmed these percentage differences in drug and alcohol use
between the EDR to be significant. As regards drug use, Chi-square = 7.37, (df = 2), p =
0.04 and the Contingency Coefficient was .28. With regard to alcohol use, Chi-square =
14.75, (df=2), p=.001 and the Contingency Coefficient was .38. The moderate and high
EDR groups reported significantly higher use of alcohol or drugs compared with the use
of the low EDR group apparent in Table 27.
