New Media Use and Mental Health of Married Women: Mediating Effects of Marital Quality.

While previous studies have investigated the influence of new media on mental health, little is known about its effects on the mental health of married women. This is a crucial research area, given that married women commonly encounter distinct mental health difficulties. Also, current research fails to provide comprehensive, population-based studies, with most relying on cross-sectional designs. Therefore, this study aimed to investigate the relationship between new media use and mental health among married women in China, utilizing a nationally representative longitudinal dataset. We utilized a balanced panel dataset from 2016 to 2020 to establish a causal connection between internet use and the mental health of these women. Our findings indicate that internet use has a positive impact on the mental health of married women in China. Additionally, a structural estimation model (SEM) with 2020 wave data was utilized to investigate various new media use effects and explore mediating pathways of marital satisfaction. Consistently, there were negative findings between new media use, marital satisfaction, and depression. Furthermore, it was determined that new media usage had a significant negative impact on married women's overall satisfaction with their spouses' housework contribution, which, in turn, negatively affected marital satisfaction as a whole. The pathways that mediate the effect of marital satisfaction on depression differ across general internet use, streaming media use, and WeChat use. Examining various theoretical perspectives, we interpreted the indirect impact of new media use on mental health through marital satisfaction as passive mediation.
