A difference-in-differences study based on CFPS data JOURNAL=Frontiers in Psychology VOLUME=Volume 15 - 2024 YEAR=2024 URL=https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2024.1462398 DOI=10.3389/fpsyg.2024.1462398 ISSN=1664-1078 ABSTRACT=Mental health is the cornerstone of public health, especially where middle-aged and older adults during the COVID-19 pandemic were concerned. The impact of Internet usage on mental health in the time of the crisis still presents a mixed picture. This study employs the PSM-DID method according to longitudinal data (CFPS) to explore whether Internet usage reduced the impact of COVID-19 on the mental health of middle-aged and older adults. The results reveal that Internet use improves the mental health of middle-aged and older adults in China, but that the impact varies between urban and rural residents. Greater marginal gains may be realized by enhancing the digital capacity of and narrowing the digital divide that exists among rural residents. Furthermore, the moderator effects model shows that people's perceptions of the Internet have an impact upon the length of time spent online and its consequent effect on mental health. The enhancement of digital capacity and proper guidance in digital education should be taken into consideration where the mental health of middle-aged and older adults is at issue.
