Abstract
Aim. The purpose of this study was to compare the effect of “acceptance and commitment therapy” and “stress inoculation training” on stress symptoms in people with broken heart syndrome.
Background. Stress is considered to be the main driving force of broken heart syndrome, while broken heart syndrome also causes stress. It seems that training the patient for correct use of coping strategies during stressful events is effective in preventing recurrence.
Method. In this quasi-experimental pre-test post-test design with control group, 62 people referred to Tohid Hospital in Sanandaj during 2016-2017 and had been diagnosed as with broken heart syndrome were considered as accessible population, out of which 30 patients were recruited by convenience sampling method and randomly assigned to three groups. Research tool was the stress syndrome scales in Persian language.  For intervention groups, the acceptance and commitment therapy and stress inoculation training interventions was conducted in weekly sessions. The questionnaire were filled out before intervention, after intervention and one month after intervention by the three groups. Data were analyzed in SPSS using descriptive and inferential statistics.
Findings. Compared with control group, acceptance and commitment therapy (F=87.65, P≤0.0001) and stress inoculation training (F=61.18, P≤0.0001) were effective in reducing stress symptoms and the effect of the acceptance and commitment therapy was remarkable. In addition to the stability of the effect of both interventions one month after intervention, the effect of acceptance and commitment therapy was found to be superior to stress inoculation training.
Conclusion. Both modalities; especially acceptance and commitment therapy, can be used as effective methods with wide applicability in preventing and reducing symptoms of stress and improving the status of people with broken heart syndrome.

Abstract
Aim. This study was conducted to compare the effect of multidimensional spiritual therapy and stress inoculation training (SIT) on physiological and psychological coordination of heart rate variability (HRV) and depression in patients after coronary artery bypass graft (CABG) surgery.
Background. Depression and other emotional disorders play an important role in reducing the physiological and psychological coordination of heart rate in patients after coronary artery bypass graft (CABG) surgery. Depression and other emotional disorders prevent the person from recovering from the pathologic condition. It seems that preparing the patient for proper coping techniques is helpful in improving emotional disorders and preventing recurrence of disease.
Method. This was a clinical trial with two experimental and one control group. The study population included patients after CABG in Tehran Cardiac Research Center, Tehran, Iran. Thirty patients were randomly selected and assigned into three groups. The instrument of this study was the DASS-21 scale and the evaluation of physiological and psychological coordination of heart rate, which was measured before the intervention and at the end of the 10th session in groups. The first experimental group was exposed to the Meichenbaum stress inoculation training for 10 sessions of 90-minute duration, and the second experimental group received multidimensional spiritual therapy. Data were analyzed using Multivariate analysis of covariance in SPSS.
Findings. Multivariate analysis of covariance showed that SIT and multidimensional spiritual therapy interventions both have a statistically significant effect in reducing depression in one-month and three-month follow-up, compared to the control group, but their effects on reducing depression was significantly different (-2.200, P=0.002). However, no statistically significant difference was observed between experimental groups in terms of changes in physiological and psychological coordination (-0.00133, P=0.1).
Conclusion. SIT intervention seems to be less effective than multidimensional spiritual therapy in reducing depression, but its effect on changes in physiological and psychological coordination is the same as multidimensional spiritual therapy.
