Description
Summary:Objective: This study adapted and translated the Trust in Oncologist Scale (TiOS) into the Tagalog Trust in Ophthalmologist Scale (TTOS) and validated the latter. Methods: The 18-item TiOS questionnaire was translated into Tagalog and validated in a cohort of 200 Filipino ophthalmology patients of a single institution. Internal consistency, construct validity, and test-retest reliabilities were determined. Exploratory factor analyses were also performed. Results: The TTOS showed high internal consistency with Cronbach alpha of 0.92, high reliability with Pearson's coefficient of 0.85, and high validity with Spearman’s coefficient of 0.67. Conclusion: The TTOS is a valid and reliable tool to measure the level of trust of Filipino patients in their ophthalmologists.
