Abstract
Aim. The aim of this study was to compare the effect of mentalization-based therapy and supportive psychotherapy on object relations in people with coronary heart disease.
Background. Cardiovascular diseases are the main cause of disability and death in different countries of the world and despite the development of various treatments, it is still highly prevalent.
Method. This experimental study was conducted in the form of the pretest-posttest design with control group and follow-up stage. The statistical population consisted of all people with coronary heart disease who referred to Imam Khomeini Hospital in Ardabil during 2018. Of this statistical population, 60 people were selected through purposive sampling and according to inclusion criteria, and were randomly assigned to two experimental groups and one control group (20 people in each group). Finally, 55 people remained until the end of interventions and evaluations. The first experimental group received 12 sessions of mentalization-based therapy, the second experimental group received 10 sessions of supportive psychotherapy, while the control group did not receive any intervention. Bell Object Relations Questionnaire was used for data collection in three stages of pre-test, post-test and follow-up. Data were analyzed using repeated measures analysis of variance and LSD post-hoc test using SPSS statistical software (version 22).
Findings. After controlling the pre-test effects, a statistically significant difference was found between the post-test mean scores of the experimental groups (mentalization -based therapy: F=19.69, P≤0.0001; and supportive psychotherapy: F=28.86, P≤0.0001) and the control group (F=0.87, P<0.43) in terms of object relations and its components. Also, the effect of supportive psychotherapy on object relations of patients with coronary heart disease was higher than that of mentalization -based therapy (P<0.01).
Conclusion. The results of the present study provides the basis for using these interventions in people with coronary heart disease.

Abstract
Aim. This study was conducted to examine the effect of mentalization-based therapy and emotion-regulated therapy based on the Gross process model on psychological well-being and quality of work-life of nurses in intensive care units.
Background. Improving nurses' well-being and satisfaction with their quality of work-life improves the nurse-patient relationship and hospitals' performance from an organizational point of view. It is necessary to provide psychological therapeutic interventions to this crucial group of health care providers.
Method. This study was an experimental  study (pre-test post-test with control group) in which 45 nurses working in intensive care units of selected Tehran hospitals, Iran, were selected by the convenience sampling method, and assigned to two intervention groups and one control group (15 nurses in each group). Reef's short-term psychological well-being and Walton's 32-item quality of work-life were used to measure dependent variables of the study. Then, mentalization-based therapy group received intervention in 8 sessions of 90 minutes as one session per week; and the treatment group based on emotion regulated therapy based on the Gross process model received the intervention in 8 sessions of 90 minutes, one session per week based on the protocol. No intervention was implemented for the control group. Data were analyzed using descriptive and inferential statistics in SPSS software.
Findings. Before the intervention, there were the highest scores for quality of work-life in the control group. At the end of the study and after the intervention, the scores of quality of work-life increased in all three groups, and no statistical significant difference was found between the groups. Before the intervention, the highest scores for psychological well-being was observed in the mentalization-based therapy group. (85.86±6.56), and after the intervention, although the psychological well-being scores of both interventions groups were higher than that of control group, but this diferrence was not statistically significant.
Conclusion. Based on the findings of this study, it seems that training sessions of mentalization-based therapy and emotion-regulated therapy based on the Gross process model improve the quality of work-life in nurses working in intensive care units, but the improvement was not statistically significant.
