Randomization
The subjects were included in the study by simple random sampling method and divided into three equal groups (n = 22) including two experimental groups (received nursing ethics education through lectures and group discussions methods) and a control group (did not received any nursing ethics training) using block randomization methods. To perform blocked randomization, the randomization code was generated by computer in permuted blocks of 6. Block randomization was performed using sealed envelope technique and computer-generated random numbers by Random Allocation Software © (RAS; Informer Technologies, Inc., Madrid, Spain).
