Introduction & Objective:
Major depression is one of the most common psychiatric illnesses and, according to the World Health Organization, by 2020, the second most common disease in the world. Since one of the important goals of treating depression is the use of measures that can, in the short term, create favorable conditions, make people change from negative emotional state to positive state of affairs. Based on theoretical knowledge, positive psychology has this feature. The aim of this study was to determine the effect of positive group psychotherapy on the hope of patients with major depressive disorder.

Materials and Methods:
The present study was an experimental study in which the population of this study was composed of patients with major depressive disorder in Yasuj, Shahid Rajaee Nursing and Psychiatric Hospital. Among the patients with the criteria for entering the study, 32 first cases were randomly assigned to the experimental group and the other 32 as the control group. After completing the Snyder Hearing Inventory in the pre-test, four sessions and weekly sessions a 90-minute psychotherapy group was established for positive psychology. Immediately after completing the post-test training sessions and two weeks afterwards, the follow up was assessed. Data were analyzed by SPSS software version 21 through independent t-test and Mann-Whitney test, Chi-square test, Fisher exact test, and ANOVA with repeated measurements at 95% confidence level.

At the beginning of the study, there was no significant difference between the experimental and control groups in terms of demographic characteristics. The hopefulness of the research units at the beginning of the study was 33.31 ± 5.31 in the experimental group and 30.72 ± 5.96 in the control group. Independent T-test did not show any significant difference between the two groups (P < 0.07). The hopefulness of the research units in the experimental group was 40.44 ± 5.9 in the first post test and 41.59 ± 5.48 in the second post test was significantly increased (P <0.001), while the hopefulness Control units of the control group in the first and second posttest have a decreasing trend toward the pretest.

According to the findings of this study, it seems that psychosocial group based on positive psychology is effective on the hope of patients with major depressive disorder.
