title: A comparative study on the effectiveness of positive psychotherapy and group cognitive-behavioral therapy for the patients suffering from major depressive disorder.
abstract: OBJECTIVE
  Aim of this experimental study is evaluating the effectiveness of two different approaches towards the treatment of major depressive disorder (MDD): Positive-oriented psychotherapy and group cognitive-behavior therapy.
  
  
  METHODS
  Eighteen out-patients suffering from major depression were randomly divided into two groups to be treated according to either of these two approaches. Both groups undertook the treatments for 12 weeks. All the subjects were tested by Beck Depression Inventory, Subjective Wellbeing Scale, Oxford test of Happiness, and the scale of Subjective Units of Distress before and after the treatments.
  
  
  RESULTS
  The results show significant differences between the two groups in terms of the variables of happiness and mental distress, suggesting that effectiveness of positive psychotherapy is more than cognitive-behavioral therapy in increasing happiness. These two approaches were significantly different in neither decreasing the acuteness of depression symptoms nor increasing subjective wellbeing.
  
  
  CONCLUSIONS
  As a whole, the results of this comparative study indicate that positive psychotherapy is more effective in increasing happiness among MDD patients.
