Background and Aim Psychological factors play a significant role in the exacerbation of cardiovascular diseases. This study aimed to investigate the effectiveness of teaching emotion regulation skill (based on dialectical behavioral therapy) on cognitive emotion regulation and Quality of Life (QoL) of patients with cardiovascular diseases.
Methods and Materials The present study has a quasi-experimental design with pretest-posttest and the control group. The statistical population of the study included all patients with cardiovascular diseases in Kermanshah City, Iran in 2018. Among them, 30 participants were selected by simple random sampling method. Then, they were randomly assigned to the two groups of experimental and control (each group 15 patients). We performed the intervention of excited ordering education based on dialectical behavioral therapy for the experimental group in eight 90-minute sessions, while the control group did not receive any intervention during this period. To collect study information, we used a short form of the emotional cognitive regulation questionnaire and MacNew Quality of Life Questionnaire. To analyze the data, we used the multivariate analysis of covariance in SPSS V. 20.
Ethical Considerations The Research Ethics Committee of Kermanshah University of Medical Sciences approved this study (Code: IR.KUMS.REC.1397.39).
Results The results showed that the scores of Positive Cognitive-Emotional Strategies and quality of life of cardiovascular patients after training of emotional regulation skills based on dialectical behavioral therapy in experimental group significantly increased in comparison with control group, and also Negative Strategies Scores were decreased (P<0.01). 
Conclusion Based on our positive study results, we recommend the therapists to use psychological treatments as complementary therapies for these patients.

Background and Aim: The purpose of this study was to evaluate the relationship between stress coping strategies and difficulties in emotion regulation mediated by marital life quality in married women with breast cancer. 
Methods & Materials: This is a descriptive correlational study. The study population included all married women with breast cancer in Amol and Babol cities of Iran in 2018. Of these, 385 were selected through a convenience sampling technique. The research instruments were Ways Of Coping Questionnaire, Difficulties In Emotion Regulation Scale and Marital Life Quality Scale.  The goodness-of-fit of proposed model was examined by Structural Equation Modeling (SEM) in LISREL software. The indirect correlations were tested by using Preacher and Hayes’ bootstrapping method . 
Ethical Considerations: This study received its ethical approval from Islamic Azad University of Tonekabon Branch (Code: IR.IAU.TON.REC.1397.029). Informed consent was obtained from all participants.

Conclusion: The proposed model had a good fit and can be used in identifying the factors affecting difficulties in emotion regulation.  It can be useful for designing and developing programs to prevent emotions problems in women with breast cancer.

Background and Aim Fibromyalgia syndrome is a chronic disease that causes widespread musculoskeletal pain. It primarily affects women and negatively impacts many aspects of a person’s psychological and social life. This study aimed to compare the effectiveness of cognitive therapy based on mindfulness and compassion therapy on automatic negative thoughts, psychological symptoms, pain intensity, and quality of life in patients with fibromyalgia syndrome.
Methods & Materials This research is a quasi-experimental study with a pre-test-post-test design with two experimental and one control group. The statistical study population consisted of all individuals with fibromyalgia syndrome referred to Mehregan Pain Clinic in Mirdamad (District 3), Seyed Khandan Clinic (District 4), and Taleghani Hospital Pain Clinic (District 1) in Tehran City, Iran. Of them, 30 patients were randomly selected and divided into three groups of experimental 1, experimental 2, and control; each group will include 10 people. The instruments used in this study included the World Health Organization quality of life questionnaire (WHOQOL BREF), pain intensity questionnaire (PIS), psychological symptoms questionnaire (Anxiety, Stress and Depression [DASS]), and automatic negative thoughts (QNS).
Ethical Considerations This study was approved by the Research Ethics Committee of Arak Branch, Islamic Azad University (Code: IR.IAU.ARAK.REC.1400.005). 
Results The analysis of covariance showed the effectiveness of both cognitive therapies based on mindfulness and compassion therapy on four variables of pain intensity, psychological symptoms, automatic negative thoughts, and quality of life (P<0.05). Comparing the two intervention methods showed that both therapies had almost the same effect on pain intensity, psychological symptoms, and automatic negative thoughts (P<0.05) but the effectiveness of mindfulness intervention on the quality of life was significantly higher than compassion intervention (P<0.05). 
Conclusion The results indicate that cognitive therapy based on mindfulness and compassion therapy are suitable for people with fibromyalgia under appropriate treatment. 

Introduction: Sleep quality is one of the effective variables in other psychological characteristics, especially in multiple sclerosis patients. As a result, the present study was conducted with the aim of determine the role of interpersonal problems and illness perception in predicting sleep quality with mediating distress tolerance in multiple sclerosis patients.
Methods: This was a cross-sectional correlational study. The research population was all patients who were members of the Multiple Sclerosis Association of Urmia township in the first quarter of 2021 year. The sample size was estimated 315 people who were selected by available sampling method. The research data were collected by Barkham et all short version of interpersonal problems inventory (1996), Broadbent et all brief illness perception questionnaire (2006), Buysse et all Pittsburgh sleep quality index (1989) and Simons & Gaher distress tolerance scale (2005) and were analyzed by Pearson correlation coefficients and path analysis methods in SPSS-19 and PLS-3 software. This research with the IR.IAU.URMIA.REC.1400.022 ethics code is approved by the ethics committee in biomedical research of Islamic Azad University of Urmia branch.
Results: The results showed that the increase of interpersonal problems and negative perception of illness led to decrease the distress tolerance and loss of sleep quality and an increase of distress tolerance improved sleep quality. In addition, the decrease of interpersonal problems and negative perception of illness with mediating distress tolerance led to improved sleep quality (P<0.01).
Conclusions: According to the results, to improve the sleep quality of multiple sclerosis patients can be increased the rate of their interpersonal problems and illness perception and decreased their distress tolerance.

Introduction: The purpose of this research was to investigate the effect of a period of resistance training and melatonin consumption on sex hormone levels, pain intensity, and sleep quality in girls with primary dysmenorrhea.
Methods: For this purpose, 60 girls with moderate primary dysmenorrhea disorder (score 4-7) were randomly placed in 4 groups: resistance training + melatonin, resistance training + placebo, melatonin supplement group, and control group.  Pain intensity, and sleep quality were assessed by the McGill questionnaire, and the Pittsburgh questionnaire respectively.  10 mg of melatonin was taken daily in two 5 mg capsules and the placebo group received the same amount of carbohydrates in the same capsule.  Weight training, three days a week for eight weeks. This circuit exercise training was in 9 stations and with a maximum of 10-12 repetitions at 30-65% of a maximum repetition in each station.  Each set and repetition was separated by 2-3 minutes and 90 seconds of rest, respectively. The blood sample was taken in the morning, fasting and 5 cc from the brachial vein from the left hand while sitting in the sitting position, and was taken by special kits. Data were analyzed by ANOVA with repeated measures and Bonferroni post hoc test at level P<0.05. All experimental procedures were approved by the Ethics committee of the Sport Sciences Research Institute of Iran (Code: ID IR.IAU.NEYSHABUR.REC.1401.008), Clinical Trial (Code: ID IRCT20230703058653N1) from the Iran Clinical Registration Center and were conducted under the Declaration of Helsinki.
Results: A significant increase in Estrogen (P<0.001) and progesterone (P<0.001) levels in the exercise + supplement group compared to all groups, and in the exercise + placebo group and the supplement group compared to the placebo group was reported. Also, The decrease in Pain intensity (P<0.001) and sleep quality (A decrease in the sleep score means an increase in the sleep quality in the output of the questionnaire) (P<0.001) in the supplement group compared to all groups and in the exercise + placebo group (P<0.05) and the exercise + supplement group compared to the placebo group showed a significant difference.
Conclusions: It seems that synergy of exercise and melatonin has affected the sex hormones level. Also, the melatonin probably helped to improve the sleep quality and pain intensity of the subjects through the adjustment of sex hormones following dysmenorrhea. Also, exercise probably has an effect on the pain intensity and sleep quality through the release of beta-endorphins and the effects of exercise on the menstrual cycle, although the finding are ambiguous.
