Purpose: This study explores changes in couples’ relationships during the COVID-19 pandemic, and analyzes the differences in the changes across three types: positive communication, criticism/defense, and demand/withdrawal. Method: A total of 600 (567 valid) Chinese respondents participated in this study, and a questionnaire was utilized to determine changes in their overall relationship, verbal and nonverbal communication, emotion, and activities with their spouses. Results: The average score of items related to positive communication is higher, compared with that of negative communication. Compared with the other two types of relationships, respondents with positive communication scored highest on all items related to positive communication and lowest on all items related to negative communication. Significant differences were noted between the positive communication types and the others. Conclusions: Results show that the relationships of couples included in this study have improved during the current pandemic. Therefore, improved consistency in the type of intimacy can lead to improved quality of couples’ relationships during the COVID-19 pandemic.
