Abstract
Background and Objectives: Thailand's demographic shift toward an aging population increases vulnerability among older adults to the long-term mental health effects of childhood trauma. While childhood adversity is linked to heightened risks of late-life depression and PTSD, the moderating role of resilience remains underexplored in Thai older adults. This study investigated whether resilience moderates the association between childhood trauma and depressive or PTSD symptoms in this population. Materials and Methods: A cross-sectional survey was conducted with 201 older patients (mean age 68.6 years) from the Family Medicine and Geriatric Psychiatry Clinics at Maharaj Nakorn Chiang Mai Hospital. Participants completed validated measures on trauma history, resilience, depression, and PTSD symptoms. A moderation analysis was performed, adjusting for covariates including education, family support, and psychiatric history. Results: The findings revealed that resilience significantly buffered the impact of childhood trauma on depression but did not mitigate PTSD symptoms. Conclusions: These results underscore the protective role of resilience against depression following childhood trauma in older adults, yet also point to its limitations in alleviating trauma-specific responses such as PTSD. This study highlights the need for trauma-informed geriatric mental health strategies and calls for further research on resilience, focusing on cultural context and adaptive mechanisms, including emotion regulation and social connectedness, in older populations.
