This study was conducted with the aim of comparing the effect of acceptance and commitment therapy and self-compassion on cognitive flexibility in anxious female students of the second year of high school. The research method was semi-experimental in two stages: pre-test and post-test. In this study, 30 people were selected through convenience sampling and randomly assigned to two experimental groups and one control group (10 people in each group). Then the experimental groups underwent 8 sessions of acceptance and commitment and self-compassion therapy, and the control group did not receive any therapy. Anxiety questionnaire and cognitive flexibility scale were used to collect data. Data were analyzed using multivariate analysis of covariance. The results showed that in the post-test stage, there is a significant difference between the acceptance and commitment and self-compassion treatment groups compared to the control group in increasing cognitive flexibility. Also, the results showed that there is no significant difference between the two treatments of acceptance and commitment and self-compassion in terms of effectiveness on psychological flexibility. Based on the findings, both acceptance and commitment therapy and self-compassion are suitable options for increasing cognitive flexibility in anxious female students of the second secondary level.

Post-traumatic growth emphasizes the fact that people experience positive changes in psychological, interpersonal and environmental dimensions after facing stressful events. The present study was conducted with the aim of developing and validating an educational program based on the post-traumatic growth model (PTG) and its effectiveness on the resilience and psychological well-being of patients with leukemia. The research method was semi-experimental with a pre-test-post-test design with a control group. The statistical population included patients referred to Tehran's Firouzgar Hospital in 1400, 30 patients were selected using voluntary and available sampling, and randomly replaced in two experimental and control groups. The tools included Connor and Davidson Resilience Questionnaire (RIS-CD) and Ryff Psychological Well-Being (RSPWB). The treatment program was held during 12 sessions, and after two months, the experimental group was followed up again. The results of covariance analysis showed that the F value obtained for resilience variable and dimensions of psychological well-being including independence dimension, mastery of the environment, personal growth, positive communication, purpose in life and self-acceptance. It is meaningful and the educational program based on the pattern of post-traumatic growth is effective on resilience and dimensions of psychological well-being (P<0.05). The results of the repeated measurement analysis are significant (P<0.01) in order to check the lasting effect of the educational program on resilience and dimensions of psychological well-being. The educational program based on the post-traumatic growth pattern as an effective and special program can be used to improve resilience and psychological well-being of patients with leukemia.

Lack of cognitive flexibility intensifies an individual’s negative thoughts about oneself.

The present study aimed to design and validate an educational program based on the posttraumatic growth model and to evaluate its effectiveness in the cognitive flexibility of leukemia patients.

In this quasi-experimental study with a pretest-posttest control group design, the statistical population consisted of all patients referred to Firouzgar Hospital of Tehran, Iran, in 2022. The sample size 30 patients were selected by the convenience sampling method and randomly allocated into the experimental and control groups. The Cognitive Flexibility Questionnaire (2010) was used to collect the required data. The educational program based on the posttraumatic growth model was held in 12 sessions, and a follow-up experiment was conducted to evaluate the durability of intervention effects. The results were analyzed using the multivariate analysis of covariance and repeated measures ANOVA in SPSS version 22.

The results showed that the F-values measured for the components of cognitive flexibility, including the perception of controllability, perception of different options, and perception of behavior justification, were significant (P<0.01), suggesting the impact of the training program based on the posttraumatic growth model on cognitive flexibility. The results of repeated measures ANOVA also indicated the persistence of the effects of the training program on cognitive flexibility (P<0.01).

The result of the research showed that the training program according to the posttraumatic growth model was effective in cognitive flexibility, and its effect persisted until the follow-up period. Therefore, this program can be used as an effective intervention to improve the cognitive flexibility of patients with leukemia.
