title: Historical perspective on the development of outcomes measures for low-vision and blind rehabilitation in the Department of Veterans Affairs.
abstract: This article reviews the instrument development process and synthesizes current research findings for three low-vision and blind rehabilitation outcomes measures developed in the Department of Veterans Affairs (VA). The examined measures include the Blind Rehabilitation Service Functional Outcomes Survey, the Functional Assessment of Self-Reliance on Tasks, and the VA Low Vision Visual Functioning Questionnaire. We examined vision rehabilitation literature using two fundamental measurement criteria to compare and contrast the instrument development process and research findings for the three measures. Our findings suggest the three measures need refinement to meet the two criteria and proposed measurement standards for instruments in this field. Advanced development goals for the instruments are identified. Measures that meet the specified and proposed measurement criteria will help establish an evidence-based system and guide practice at the VA and in the field.
