Today, the survival of women with breast cancer after diagnosis has increased, but for this category of patients, not only survival is important, but adherence to treatment after the occurrence and diagnosis of the disease and increased concern about the quality of life are also important. The effectiveness of various psychological treatments on adherence to treatment and quality of life of these patients has been investigated, but there is a gap in research regarding the comparison of the effectiveness of compassion-based therapy and behavioral activation therapy on the studied variables.

The purpose of this research was to compare of the effecacy of compassion-based therapy and behavioral activation therapy on adherence to treatment and quality of life in women with breast cancer.

The design of the current research was semi-experimental, of pre-test-post-test type with a control group and a two-month follow-up. 45 women with breast cancer in Gorgan during the years 2021 and 2022 were placed in three groups of compassion-based therapy, behavioral activation therapy and control group by simple random sampling method. To collect data, were used for Medication Adherence Scale (Morisky et al., 2008) and Quality of Life Questionnaire for cancer patients (European Organization for Research and Treatment of Cancer). participants in the experimental groups underwent the interventions of compassion-based therapy (Gilbert, 2006) and behavioral activation therapy (Dimidchian et al. et al., 2008) were included in 8 sessions of 90 minutes. Also, the data were analyzed by repeated measurement variance analysis and LSD follow-up test with the help of SPSS19 software.

The findings of the research showed that both compassion-based therapy and behavioral activation therapy were effective on the adherence to treatment and quality of life of women with breast cancer (p<0.05). Also, the results showed that behavioral activation therapy was more effective than compassion-based therapy, and this significant level was stable in the follow-up phase (p<0.05).

Cancer has experienced alarming growth in the last two decades and is considered as an urgent health problem of modern life. Meanwhile, breast cancer is one of the most common types of cancer, and its annual incidence is increasing at a rate of 1.8 to 2% in the world, and it ranks first among all women's cancers. However it has a major difference from other chronic diseases. In addition to requiring long-term care and treatment, it cannot be completely cured. This study  aimed to investigate the effectiveness of group self-healing training on distress tolerance, emotional reactivity and anxiety in women with breast cancer in Isfahan. It was semi-experimental in the form of pre-test-post-test with a control group. The statistical population included all women with breast cancer in Isfahan who had referred to support center for cancer patients in the first quarter of 2011, and their number was 93 people in this period of time based on the statistics received from the counseling center. 30 people were selected as the sample through available sampling and were placed in two experimental (15 people) and control (15 people) groups. The used tools were Simons & Gaher's distress tolerance (2005), Matuo & Nock's emotional reactivity (2008) and Reese and Patterson anxiety (1985) questionnaires. Self-healing group training sessions based on the protocol of Latifi and Meravi (2017) adapted from Loyd and Johnson (2010) were conducted during 14 sessions. The data were analyzed using SPSS-24 software in two descriptive and inferential (normalization and MANCOVA) according to the investigated hypotheses.   The results showed that group self-healing training on distress tolerance and its dimensions (tolerance, evaluation and regulation), emotional reactivity (sensitivity, intensity and stability) and anxiety (fear of physical symptoms, fear of cognitive control distortion, fear of observing anxiety reactions) is effective in women with cancer in Isfahan (P<0.05). Therefore, it seems that this method can be used for breast cancer patients. The reason for the effectivness of self-healing training on reducing cancer patients’ anxiety and stress in physical and psychological dimensions can be attributed to the effects of direct training in the field of fear and anxiety in this intervention. In this treatment method for treating anxiety, strategies include self-education and communication management (keeping calm, avoiding haste, avoiding useless discussions, speaking in a soft tone, not reacting quickly and not judging quickly), trusting others (patience, calmness, happiness and entrusting the solution of the problem to a higher power), adjustment of idealism (reducing the desire to be perfect and accepting mistakes as an inseparable part of every human being), order and time management (having discipline, planning and prioritization and doing necessary daily tasks), correct connection with the mind (living in the present moment), and using physical and muscle relaxation techniques (muscle relaxation, breathing, hydrotherapy, swimming, walking, religious behaviors, watching the sky, listening to the sound of water, meditation and yoga, the use of relaxing audio files at least once a day) were used and the patients were helped to reduce their anxiety to a great. Considering the confirmation of the effectiveness of self-healing training on reducing emotional reactivity and anxiety in people with cancer, it is suggested that doctors and nurses pay attention to their psychological condition in addition to physical treatments for these patients and if they observe psychological problems caused by the disease, refer them to psychologists and counsellors. It is also suggested to set up counseling and psychological centers for cancer patients in hospitals.

The results of the research indicated that cognitive behavioral intervention is effective on psychological distress in women with breast cancer in Tehran. Therefore, the results of this research show the necessity of using psychological treatments along with common drug treatments for patients.

The research instruments were the Conor-Davidson Resilience Questionnaire, Garnowski et all, Cognitive Emotion Regulation Inventory), World Health Organization Quality of Life Scale, and Schneider hopefulness et all, for data analysis, structural equation modeling was used. The findings showed that the direct effect of quality of life on hopefulness of patients with breast cancer was equal to (t = 1.98 and β = 0.31) and Resilience had a significant direct (t=2.38 & β=0.37) and indirect (t=2.03 & β=0.14) effect on the hopefulness (mediating of quality of life) (p <0.05). Also, positive cognitive emotion regulation and negative cognitive emotion regulation did not have a significant direct effect on hopefulness. Positive cognitive emotion regulation on the hopefulness had significant indirect effect (t = 2.14 and β = 0.18) and negative cognitive emotion regulation on the hopefulness had significant indirect effect (t = 2.09 and β = 0.16) (mediating of quality of life) (p <0.05). The results of the model analysis showed that the factor structure of the research scales was confirmed. The results of the conceptual model test showed that the fitting indices of the research model are in a favorable situation. Increasing the rate of reproduction directly increases the hopefulness of patients with breast cancer and also increases the level of hopefulness of these patients by increasing the quality of life. Also, increasing the cognitive emotion regulation by increasing the quality of life increases the level of hope of patients.
