Background: Due to the chronic and long duration of multiple sclerosis and the importance of depression and identity crisis in these patients, the need to pay attention to the use of group behavioral activation therapy in these patients has been neglected. Aims: The present study aimed to determine the effectiveness of group behavioral activation therapy on depression and identity crisis in patients with multiple sclerosis. Method: The present study was a quasi-experimental with a pretest and posttest design with a control group. The statistical population included all female patients with inflammatory bowel disease who were members of the inflammatory bowel disease association of Karaj in the period from May to December 2020. By purposive sampling method, 30 inflammatory bowel patients were selected based on inclusion and exclusion criteria and randomly divided into two groups (15 people in the experimental group and 15 people in the control group) were replaced. Data collection tools included Beck et al. Depression Questionnaire (Second Edition (1996)) and Rajai et al.'s Identity Crisis Questionnaire (2008). The experimental group was treated with group behavioral activation in 8 sessions of 60 minutes, but the control group did not receive any intervention. For statistical analysis of data, mean, standard deviation and multivariate analysis of covariance were used with SPSS software version 24 at a significance level of α= 0/05. Results: The results showed that in the post-test, after adjusting the post-test scores on the pre-test scores, the mean scores of depression and identity crisis in the experimental group significantly decreased compared to the control group (p< 0/001). Conclusions: Based on the results of the study, group behavioral activation therapy should be used as a complementary therapy along with other treatment methods to improve the psychological status of multiple sclerosis patients.

Background: Individuals with gender dysphoria often face challenges, social discrimination, and difficulties in defining their own identity. The existing literature highlights the need for therapeutic interventions tailored to the unique psychological needs of this population. Unified group psychotherapy, which incorporates multiple therapeutic approaches, offers a promising solution to support individuals with gender dysphoria in exploring and affirming their identities and improving their positive self-concept and resilience. However, empirical research on the effectiveness of such interventions in addressing identity crises and improving self-concept in individuals with gender dysphoria is still limited.
Aims: The aim of the present study was to determine the effectiveness of unified group psychotherapy on identity crises and self-concept in individuals with gender dysphoria.
Methods: The present research employed a quasi-experimental pretest-posttest design with a control group. The statistical population comprised all individuals with gender dysphoria in Isfahan province in the year 2022. Thirty individuals were selected using convenience sampling method and randomly assigned to two groups: experimental (n= 15) and control (n= 15). The research instruments used in this study were the Identity Crisis Questionnaire (Ahmadi, 1999) and the Self-Perception Profile (Harter & Pike, 1984). Multivariate analysis of covariance (MANCOVA) was employed to analyze the data using SPSS version 25.
Results: The results indicated that in both the identity crisis and self-concept variables, the psychotherapy group in the posttest phase showed significantly lower means compared to the control group (p< 0.05).
Conclusion: Based on the findings, it can be concluded that with the assistance of unified group psychotherapy, variables such as identity crisis and self-concept in individuals with gender dysphoria can be influenced. This approach in this field can contribute valuable practical knowledge and experience to clinical practice and aid in improving therapeutic methods.
