Abstract

The CATOR Framework for the Conceptual Modeling of Assistive Technology Device (ATD) Outcomes assumes antecedent factors that inform it and influence component variables. The CATOR Framework provides a conceptual structure for developing models that identify characteristics of individuals related to ATD use. This paper proposes a model of factors influencing consumer and provider predispositions to particular ATD procurement. The literature on antecedent factors influencing predispositions to specific ATD procurement is summarized. The decision that a particular ATD is appropriate and desirable is a critical step in the process of service provision. It is affected by a broader societal climate that fosters unique personal climates for both provider and consumer that uniquely predispose them to particular AT decisions. The antecedent model can contribute to AT clinical practice and outcomes research by highlighting factors important to consider prior to ATD procurement.
