مقایسه کارایی و اثربخشی شناخت درمانی بک با شناخت درمانی تیزدل در درمان افسرده‌خویی

 Introduction: The aim of this research was to investigate the efficacy of Beck’s cognitive therapy versus Teasdale’s in treatment of dysthymia. Method: Six subjects (two males and four females) were selected by convenient sampling and were randomly assigned to two treatment groups. The methodology was a multiple-baseline experi-�mental single case study. Subjects completed Beck’s Depression Inventory (BDI) and Depression- Anxiety-Stress Scale (DASS) at pre-treatment (baseline), treatment (4 and 8 sessions),  post-treat-ment (twelfth session), and at follow-up (two months after treatment). Also, subjects completed the Dysfunctional Attitude Scale (DAS), and the Internal-External Control Scale (IECS) at pre-treat-ment (baseline) and post-treatment (twelfth session). Results: The results revealed that both Beck’s and Teasdale cognitive therapies were effective in decreasing dysthymic symptoms that was more prominent with the latter method. Conclusion: Teasdale’s cognitive therapy can be more effective than Beck’s in reducing dysthymic symptoms.
