As Taiwan transitions to a super-aged society, gaps are emerging between long-term care (LTC) policy and public preferences for elder care. Using data from the 2016 and 2021 Taiwan Social Change Survey, this study examines the determinants of preferences for four elder care models for oneself and family members. The findings show declining support for full-time family care and rising acceptance of institutional and mixed models, particularly for self-care. Higher education predicts lower support for family care, while filial piety remains influential but is weakening. The divergence between preferences for others and for oneself reflects shifting values and growing demand for professionalized care. As Taiwan’s LTC 3.0 entered a phased rollout beginning in September 2025 and will continue to expand service scope through 2026, these findings provide an empirical benchmark for assessing whether ongoing policy adjustments—particularly regarding institutional capacity, affordability, and hybrid community-based services—are aligned with changing public expectations.
