Cross-cultural adaptation and the evaluation of psychometric properties of the Sinhala version of the general rehabilitation adherence scale (GRAS-Sin)

However, its ceiling effect may limit differentiation at higher adherence levels. Further studies are required to address the limitations of the ceiling effect in the present study.
