A number of 30 male students were recruited based on inclusion and exclusion criteria, as well as a clinical interview conducted by a specialist.

The SPSS software, version 18 was used to analyze the data. Results of MANCOVA indicated that the ACT reduced perfectionism (P< .001) and the sense of shame (P<.05) in the experimental group.
