A framework for the conceptual modelling of assistive technology device outcomes

Area of Science:

• Rehabilitation Engineering
• Assistive Technology Outcomes Research

Background:

• Effective assistive technology outcomes research requires device-specific conceptual models.
• An overarching framework is needed to guide the development of multifarious device-specific models.

Purpose of the Study:

• To propose a conceptual framework for assistive technology outcomes research.
• To facilitate the creation of device-specific causal models.

Main Methods:

• Literature review to identify needs for a conceptual framework.
• Specification of framework assumptions.
• Description and discussion of the framework's implications.

Main Results:

• Assistive technology outcomes result from interactions between device characteristics, users, and environment.
• Initial stages include device procurement and introductory use, moderated by co-factors.
• This leads to short-term and potential long-term outcomes.

Conclusions:

• The framework can accelerate the development of device-specific causal models.
• It aids in establishing a research agenda for assistive technology outcomes.
• Highlights needs for outcome measures and identifies testable hypotheses regarding device usage.
