Abstract
Despite the growing number of older adults engaging in voluntary migration, there is a lack of knowledge about their psychological well-being in cross-cultural contexts. This cross-sectional study investigated factors associated with psychological well-being among older Chinese migrants residing in Chiang Mai, Thailand. Between December 2024 and February 2025, 204 Chinese migrants aged 60 and above who had resided in Chiang Mai for at least six months participated in a survey in Chinese. The survey measured sociodemographic and psychosocial factors including perceived health, income, marital status, number of co-residing family members, social support, acculturative stress, sense of mastery, and loneliness. Multiple regression analysis showed that gender (female) (p = 0.006), better perceived health status (p = 0.021), higher income (p = 0.007), more co-residing family members (p = 0.037), a greater sense of mastery (p = 0.009), and lower levels of loneliness (p < 0.001) were each independently associated with better psychological well-being. In contrast, neither general family support nor acculturative stress was a statistically significant predictor. These findings highlight the significant roles of financial security, family co-residence, personal empowerment, and social connectedness in shaping overall well-being. Strategies to improve psychological well-being in this population should focus on strengthening emotional connectedness, supporting the development of meaningful family and social relationships, and supporting economic stability.
