Further assessment determined that the scores of both experimental groups were significantly lower than that of the control group, and that the difference between the integrated practical training experimental group and the control group was extremely significant ( P < .01), while the difference between the training group and purely theoretical group approached the threshold of significance ( P = .051).
SNK test results revealed that the scores for 5 factors: SCL90-2 (symptoms), SCL90-3 (interpersonal sensitivity), SCL90-4 (depression), SCL90-5 (anxiety), and SCL90-6 (hostility) in the integrated practical training experimental group were significantly lower than those of the control group ( P < .01), while those for the remaining factors with the exception of SCL90-8 (paranoid) approached significance.
With the exception of SCL90-8 (paranoia), the difference between the practical training experimental group and the control group for the remaining 4 factors was also marginally significant (Table 2 ).
