Functional Variability and Ecological Sensitivity in Thai Shelters: Implications for Mental Health Rehabilitation

Abstract

Occupational performance is shaped by complex interactions between individuals and their environments, yet traditional assessments in mental health rehabilitation often overlook how context influences functional outcomes. This study explored whether short-term variability in observed performance reflects ecological sensitivity and adaptive engagement, with implications for recovery-focused psychosocial rehabilitation. We conducted a two-week observational study with 60 Thai adults residing in either community-based shelters or institutional care facilities for individuals with psychiatric and cognitive disabilities. Participants completed structured, culturally adapted work tasks rated on motor, process, and social interaction domains using the Assessment of Work Performance. Additional screening measured cognitive functioning and psychiatric symptom severity. While group averages showed minimal overall change, substantial individual variability revealed diverse occupational responses to different living environments. Participants in community-based shelters demonstrated more consistent functional gains despite having lower average cognitive screening scores, underscoring the role of ecological fit. Improvements in motor, process, and social domains often occurred independently, suggesting that changes in one area may not automatically generalize to others. These findings challenge assumptions that stable scores always indicate better outcomes and highlight those fluctuations in functional performance can signal meaningful adaptation to supportive contexts. Integrating culturally relevant, performance-based assessments into psychosocial rehabilitation may help identify needs that standardized screenings miss, enabling more personalized, recovery-oriented planning. This approach could strengthen community mental health services by ensuring that program structures align with both individual capacities and ecological opportunities.
