The instruments were Enrich marital satisfaction questionnaire, and The European Heart Failure Self-care Behavior  (EHFSCB). Collected data were analyzed in SPSS version 16 using descriptive and inferential statistics.
Findings. The results showed that 58.8 percent of participants were male, with a mean age of 59.66 years. The mean score of marital satisfaction was 145.6±41.98. Most participants (46.9 percent) had partial marital satisfaction. The mean score of self-care was 34.5±12.24 and most participants (41.2 percent) reported good self-care. There was a statistically significant negative correlation between the marital satisfaction and self-care scores.
Conclusion.

Abstract
Aim. The aim of this study was to compare the effect of mindfulness-based cognitive therapy and acceptance and commitment therapy on sleep quality and health promoting lifestyle behaviors in patients with heart failure.
Background. Consequences of heart failure create problems with sleep quality and lifestyle that affect the course of the disease. Mindfulness-based cognitive therapy and acceptance and commitment therapy are some of the potential effective interventions on those.
Method. The present study was a quasi-experimental with a pretest-posttest design and a control group with quarterly follow-up. The sample size was 45 people which were purposefully selected and then randomly assigned to two experimental groups (n=30) and one control group (n=15). Data were collected in three stages using the Sleep Quality Index Pittsburgh  of Boyce et al. (1989) and the Health-Promoting Lifestyle Questionnaire of Walker et al. (1987). Mindfulness-based cognitive therapy and acceptance and commitment therapy for experimental groups were performed and data analysis was performed in SPSS-25 software through analysis of covariance.
Findings. Both acceptance and commitment therapy and mindfulness-based cognitive therapy in post-test and follow-up (F=181.224, P≤0.0001) and (F=62.315, P≤0.0001), improved sleep quality and health-promoting lifestyle behaviors when compared to the control group. Despite the effect of both interventions, the superiority of acceptance and commitment therapy (P< 0.001) on health promoting lifestyle was found. There was no statistically significant difference between two interventions (P=0.967) in terms of improving sleep quality.
Conclusion. According to the results, both interventions were effective on sleep quality and health-promoting lifestyle behaviors, especially acceptance and commitment therapy was more effective on health-promoting lifestyle behaviors, so, in medical settings it can be used along with medical treatments for patients with heart failure.

Abstract
Aim. This study was conducted to compare the effect of “mindfulness-based cognitive therapy” and “acceptance and commitment therapy” on fatigue and quality of life in men with heart failure.
Background. Fatigue, as one of the important symptoms and complications of heart failure, affects the quality of life of the patients, their self-care and daily task performance. Mindfulness-based cognitive therapy and acceptance and commitment therapy may have an effect on these problems.    

Method. This research was semi-experimental with a pre-test post-test design and control group within a three-month follow-up period. Forty five men with heart failure were purposefully selected and randomly allocated to two experimental groups and one control group (15 people in each group). Data were collected in three stages using the Iowa Fatigue Scale, and Minnesota Living with Heart Failure Questionnaire. Data analysis was done in SPSS-25 software with mixed analysis of variance test.

Findings. After intervention and in follow-up stages, both mindfulness-based cognitive therapy and acceptance and commitment therapy were effective on fatigue and quality of life in men with heart failure. The follow-up test showed a greater effect of acceptance and commitment therapy on quality of life and no statistically significant difference was found between the experimental groups in terms of effect on fatigue. 

Conclusion. Both interventions, especially acceptance and commitment therapy, can be used as effective interventions on fatigue and quality of life along with medical treatments for men with heart failure in medical centers.
