Objectives: This study examines WeChat use among family caregivers of persons living with schizophrenia (PLS), its socio-demographic correlates and relationship to caregiving experiences, including perceived stress, stigma, coping, social support, family functioning, and caregiving rewarding feelings. Methods: A cross-sectional study was conducted with 449 family caregivers of PLS. Face-to-face interviews were conducted to collect information on socio-demographics, WeChat use, and a range of caregiving experiences. Results: The results indicated that nearly half (46.8%) of caregivers were WeChat users. WeChat use was associated with higher education (OR = 3.34–9.88, 95% CI : 2.01, 24.77), and younger age (OR = 0.94, 95% CI : 0.92, 0.97). Compared to non-users, WeChat users reported less stigma (b = −1.84, 95% CI : −3.40, −0.28), higher social support (b = 6.62, 95% CI : 2.73, 10.50), better family functioning (b = 1.08, 95% CI : 0.38,1.78), and more caregiving rewarding feelings (b = 3.93, 95% CI : 2.01, 5.85). WeChat use among caregivers of PLS was lower than that found in the general population, which warrants specific attention to this group with alternative support and resources provided to them. Conclusions: WeChat use is associated with more favorable caregiving experiences, and thus serves as a promising medium for further health intervention to support family caregivers, and improve their well-being.
