Abstract
Aim. The present study aimed to compare the effect of schema therapy and dialectical behavior therapy on lifestyle of women with coronary artery heart disease.
Background. Given that an unhealthy lifestyle is one of the main determinants of early onset of coronary heart disease in adulthood and its resulting mortality, the need for therapeutic interventions in this group of patients seems necessary.  
Method. This experimental study (pre-test-post-test with control group and follow-up) was conducted on women with coronary heart disease in Tehran in 2019-2020. A total of 45 female patients were selected by available sampling method and randomly allocated to two experimental group and one control group (15 people in each group). Experimental and control groups were assessed during the pre-test, post-test and one-month follow-up stages by Lali et al. (2012) lifestyle questionnaire. Eight sessions of group schema therapy (for one experimental group) and eight sessions of group dialectical behavior therapy (for another experimental group) were held (two sessions per week for 4 weeks). The data were analyzed using repeated measures analysis of variance in SPSS V.23.
Findings. Both interventions were effective in promoting lifestyle in women with coronary heart disease (p≤0.0001). Also, group dialectical behavior therapy had a greater effect on lifestyle promotion in women with coronary heart disease compared with group schema therapy (p≤0.0001).
Conclusion. Training of the use of group dialectical behavior therapy is recommended as an effective intervention method for improving lifestyle of women with coronary heart disease.

Abstract
Aim. The aim of this study was to compare the effect of integrative behavioral couple therapy, narrative couple therapy, and couple schema therapy on affective capital and depression among people with coronary artery disease.
Background. Coronary artery disease is one of the heart diseases that can cause problems for couples.
Method. This was a semi-experimental study with a pretest and posttest design and control group. The statistical population consisted of people with coronary artery disease and their spouses out of which 64 couples were selected by purposive sampling method and randomly assigned to three experimental groups and a control group (16 couples in each group). Affective Capital Questionnaire and Depression Inventory of Beck was used to assess dependent variables in two stages. The three intervention groups were each treated for 8 sessions of 90 minutes and the control group did not receive any treatment. The data were analyzed in SPSS by descriptive and inferential statistics.
Findings. In terms of affective capital, there was a statistically significant difference of integrative behavioral couple therapy, narrative couple therapy and couple schema therapy with the control group (p­≤0.001), and of integrative behavioral couple therapy with narrative couple therapy and couple schema therapy (p­≤0.001). For depression, there was a statistically significant difference of the three intervention groups with the control group, and of integrated behavioral couple therapy and couple schema therapy with couple narrative therapy (p<0.05).
Conclusion. According to the results, integrative behavioral couple therapy, couple schema therapy and narrative couple therapy are effective in increasing affective capital and reducing depression in people with coronary artery disease and their spouses. It is recommended that these three interventions be used for these patients and their spouses in cardiovascular disease centers.
 

Abstract
Aim. The aim of this study was to compare the effect of narrative couple therapy, couple schema therapy and integrative behavioral couple therapy on hope and perceived stress among patients with coronary artery disease and their spouses.
Background. Coronary artery disease is one of the heart diseases that can make couples face problems and need help.
Methods. This research was a semi-experimental study with a pretest and posttest design and with a control group. The statistical population was people with coronary artery disease and their spouses in the winter of 2021. Sixty four couples were selected by purposive sampling method and randomly assigned to three experimental groups and a control group (16 couples for each group). Hope scale of Snyder and perceived stress of Leung et al. were used to assess dependent variables in two stages. The three intervention groups were each treated for 8 sessions of 90 minutes and the control group did not receive any intervention. The data were analyzed by analysis of covariance and post-hoc Bonferroni test.
Findings. The results showed that there was a statistically significant difference of integrative behavioral couple therapy and couple schema therapy with the control group in terms of hope (P≤0.0001), but there was no statistically significant difference between the narrative couple therapy and control group and between three interventions. About the perceived stress, the results showed that there was a statistically significant difference of integrative behavioral couple therapy, narrative couple therapy and couple schema therapy with the control group (p≥0.05).
Conclusion. Considering the effect of integrative behavioral couple therapy and couple schema therapy in increasing hope and effect of the mentioned two interventions and narrative couple therapy in reducing perceived stress among people with coronary artery disease and their spouses. It is recommended to use these interventions in cardiovascular treatment centers.
