Prior to the intervention, the control (n = 76, mean 59.15) and intervention group (n = 78, mean 56.97) did ot differ significantly in the certainty assigned to their responses (Mann Whitney U = 2708, z = −.92, p > 0.05).
After the training the intervention group (n = 78) were significantly more certain of the risk of abuse (mean 64.64) than the control group (n = 76, mean 61.41), Mann Whitney U = 3598, z = 2.29, p = 0.02. See Table 4.
