夫妻沟通方式与抑郁的关系及样本类型的调节作用研究

Objective     To explore the relationship between marital communication patterns and depression in a clinical sample versus a general sample.  Methods     This study was conducted between two samples recruited in 2016, including 148 outpatients with marriage problems from a mental health hospital in Beijing (clinical group), and 400 normal married participants (control group).  A self-developed Demographic Questionnaire, Chinese version of PHQ-9 (PHQ-9-C) and Chinese version of CPQ-SF（CPQ-SF-C）were used to measure the demographic information, depression and communication patterns of the participants.  Hierarchical regression analysis was used to examine the moderate effect of different types of samples on the relationship between marital communication patterns and depression.  Results     (1) Compared with the control group,  clinical group scored higher in depression, male demand/female withdraw, female demand/male withdraw，total demand/ withdraw and criticize/defend，but scored lower in constructive communication (P<0.05) .  (2) Two groups achieved similar scores in alternative demand/ withdraw (P>0.05) .  (3) Hierarchical regression analysis showed that, male demand/ female withdraw，female demand/male withdraw，total demand/withdraw, alternative demand/withdraw, criticize/ defend could positively predict depression (P<0.05), when gender, educational attainment, and if the participant has a child were controlled, while constructive communication could negatively predict depression (P<0.05).  (4)  After bringing the product terms of male demand/female withdraw，female demand/ male withdraw, total demand/ withdraw，alternative demand/withdraw criticize/ defend, constructive communication with sample type into the regression model，respectively, the results demonstrated that the interaction between male demand/ female withdraw and sample type, as well as that between constructive communication and sample type were significant (P<0.05).  The type of the sample played a moderate role in the relationship between male demand/female withdraw and depression, and the relationship between constructive communication pattern and depression (△ R²=0.011, P<0.05; △ R²=0.019, P<0.05).  Conclusion     Sample type plays a moderating role in the relationship between marital communication pattern and depression, especially in the relationship between male demand/female withdraw and depression, as well as that between constructive communication pattern and depression.
