Background: Cancer is a complex, debilitating, and common disease with many dimensions, consequences, and psychological, biological, and social complications. We aimed to investigate the structural equations of treatment adherence based on emotional, cognitive regulation mediated by coping styles in women with breast cancer undergoing chemotherapy. Methods: The present study was a correlational study using structural equation modeling. The statistical population included patients with breast cancer referred to specialized cancer clinics in Tehran between October and February 2018. The sample consisted of 250 patients with breast cancer who were selected by convenience sampling. Data were obtained using the Folkman and Lazarus Coping Strategies Questionnaire, the Cognitive Emotion Regulation Questionnaire (CERQ), and Morisky Medication Adherence Scale (MMAS-8). Data were also analyzed using correlation coefficients, Pearson’s correlation matrix, multiple regression, and structural equation modeling. Also, all statistical calculations were performed using Amos 22 and SPSS 22 software. Results: Emotion regulation had a direct effect on coping strategies (β=0.48, P<0.001) and adherence to treatment (β=0.63, P<0.001). Coping strategies had a mediating role in the relationship between emotion regulation and adherence to treatment (AGFI=0.98, RMSEA=0.067). Conclusion: There is a relationship between emotion regulation and adherence to treatment and coping strategies has a mediating role in women with breast cancer undergoing chemotherapy.

Background and Objective:This study assessed the efficacy of Acceptance and Commitment Therapy (ACT) on weight loss and cognitive emotion regulation in obese people. Methods:To do this study, 29 obese people with BMI < 29.9 were selected by purposeful sampling at the beginning, who completed demographic questionnaire and emotional cognitive regulation questionnaire. The participants' body mass index (BMI) was measured at the first meeting and at the end of the treatment. Participants were assigned into the intervention and the control groups. The intervention group participated in acceptance and commitment group therapy sessions for five months and at the end of the treatment sessions, they completed the questionnaires again. Statistical methods included Chi-square test, t-test for comparing two independent groups and analysis of covariance (P<0.01). Results:The findings showed that the acceptance and commitment therapy can reduce BMI; it also reduces negative strategies and increases the positive strategies of emotional cognitive regulation (P<0.01). Conclusion:The present study showed that the acceptance and commitment group therapy resulted in weight loss and improved emotion regulation in people with obesity. Therefore, it is recommended to use this therapeutic approach for obese individuals.

Background: Cardiovascular disease is the most common cause of death from non-communicable diseases. The purpose of the present study was to determine the effectiveness of acceptance and commitment therapy on health anxiety and adherence to treatment in patients who underwent open-heart surgery. Materials and Methods: The research method was semi-experimental with pre-test and post-test design. The statistical population consisted of all patients with heart disease in Tehran in 2019, 45 of whom were divided into experimental and control groups. data were collected using the health anxiety questionnaire and adherence to treatment questionnaire. Data were analyzed by analysis of covariance and SPSS software. Results: The results showed that acceptance and commitment therapy significantly reduced health anxiety (F=83.60, P<0.0001) and increased adherence to treatment (F=271.32, P<0.0001). Conclusion: It can be concluded that acceptance and commitment therapy was effective in increasing adherence to treatment and decreasing health anxiety.

Background: Cognitive rehabilitation is a way to restore lost cognitive capacities. This study aimed to investigate the effectiveness of cognitive rehabilitation therapy on cognitive functions (working memory, concentration, and attention) of adolescents living in boarding schools in Tehran. Methods: This study was a quasi-experimental research with pre-test and post-test design. The statistical population includes all adolescents living in welfare boarding schools in the age group was 15 to 18 years old, and they were in Tehran in 2018. Out of 100 people, 60 people who had problems in the mentioned variables were randomly selected, and randomly divided into two groups of 30 people. The first group underwent eight individual sessions of cognitive rehabilitation therapy (by NBK software), and the second group, as a control group, did not receive any treatment. Data were analyzed by multivariate analysis of covariance and Spss.22 software. Results: The results showed that the effectiveness of cognitive rehabilitation therapy was effective on cognitive functions (working memory, concentration, and attention) of adolescents (P<0.001). Conclusion: It can be concluded that cognitive rehabilitation can successfully affect numerous aspects of cognitive functions, while numerous medical therapies may be required to treat each mere aspect. Further evaluations are strongly recommended.
