Developmental trajectories of self-efficacy and its predictors among people with severe disabilities.

PURPOSE/OBJECTIVE: The aim of this study was to examine the developmental trajectories of self-efficacy in individuals with severe disabilities and to identify predictive factors accounting for variations. RESEARCH METHOD/DESIGN: in South Korea. RESULTS: < .001). These patterns indicate more gradual increases among individuals with higher initial levels of self-efficacy and steeper growth trajectories among those with fewer initial resources. CONCLUSION/IMPLICATIONS: The findings suggest that although individuals with severe disabilities who lack initial resources may begin with lower levels of self-efficacy, they can achieve substantial developmental gains through environmental support and accumulated experience. Self-efficacy thus appears to function as a malleable psychological resource within rehabilitation contexts, highlighting the potential of targeted environmental and intervention-based strategies to promote adaptive developmental trajectories.
