To analyze the obtained data, co-variance analysis method&nbsp;was used, indicating a significance difference between mean depressions in the three groups in posttest stage.<br> However, this difference was not significant in follow-up stage. Moreover, there was a significant difference&nbsp;between dysfunctional attitude mean in the three groups in posttest stage; such a difference was significant in&nbsp;follow-up stage as well.
