Depression is one of the most important consequences of cardiovascular diseases (CVDs), and to control and treat it, it is necessary to identify its direct and indirect triggers and underlying factors. Therefore, the current study aims to evaluate and investigate the mediator role of aggression in the relationship between marital stress and depression.
The sample of current cross-sectional study includes 212 patients with coronary artery disease (CAD) in Iran evaluated from Jan to Jun 2017. The required data were gathered using Beck's Depression Inventory (BDI) questionnaire, Buss and Perry's Aggression Questionnaire (BPAQ), and Hudson's Marital Satisfaction Index (HMSI). The data were analysed using Pearson's correlation coefficient and structural equation modeling (SEM) using SPSS20 and AMOS software.
The mean age of participants (68.4% male) was 58.5 ± 8.9. The results show that there is a significant positive relationship between all the variables ( < 0.05). The results of the model show that marital stress cannot directly predict depression ( = 0.586). However, through aggression, marital stress can significantly predict 18% of the variance of depression ( < 0.001).
Not directly, but indirectly through aggression, marital stress can significantly predict increased depression among patients with CAD. The physiological and psychological pathways of the findings can be discussed.
抑郁症是心血管疾病（CVDs）最重要的后果之一，为了控制和治疗抑郁症，有必要识别其直接和间接触发因素及潜在因素。因此，本研究旨在评估和调查攻击行为在婚姻压力与抑郁症关系中的中介作用。
本横断面研究的样本包括2017年1月至6月在伊朗评估的212例冠心病（CAD）患者。所需数据通过贝克抑郁量表（BDI）问卷、布斯与佩里攻击性问卷（BPAQ）和哈德森婚姻满意度指数（HMSI）收集。使用SPSS20和AMOS软件，通过皮尔逊相关系数和结构方程模型（SEM）对数据进行分析。
参与者的平均年龄为58.5±8.9岁（男性占68.4%）。结果表明，所有变量之间均存在显著正相关（<0.05）。模型结果显示，婚姻压力不能直接预测抑郁症（=0.586）。然而，通过攻击行为，婚姻压力可以显著预测抑郁症18%的方差（<0.001）。
婚姻压力并非直接而是通过攻击行为间接显著预测CAD患者抑郁症的增加。可以讨论该研究结果的生理和心理途径。
