Examination of current instruments

Field Scan 1
Name: At Instrument Update and Review
Short Description: A comprehensive search of published AT instruments was performed. The instruments are primarily those that are available commercially. A searchable database, called ID-AT-Assessments, cataloging the nature of the instruments’ questions and their purposes is completed. This data set and instrument library serves as a guide for practitioners to support the selection of the best measures for their clinical situations.
Technical Report: Assistive Technology Instrument Update and Review
Field Scan 2
Name: Treatment of AT in Current/Emerging Health & Rehabilitation Outcome Measures
Short Description: This field scan identified hundreds of health and rehabilitation instruments. 100 were selected and critically reviewed in regard to the inclusion of AT and the measurement issues surrounding the use of AT. The results are published in the American Journal of Physical Medicine & Rehabilitation (2005) 84 (10), 78-793.

This field scan also worked with the authors of several instruments under development to identify AT inclusion and scaling issues and to provide recommendations.

Literature review

Field Scan 7
Name: Review of Taxonomies Related to Domains of Assistive Technology Outcomes
Short Description:This field scan examines the intersection of performance taxonomies domains across taxonomies to identify a common language for AT outcomes discussions. A review of 10 generic taxonomic models including the Nagi Model (1965), ICIDH (1980, 1993), Rehabilitation Indicators (1983), NCMRR Research Plan (1993), Quality of Life Taxonomy (Spilker & Revicki, 1996), Characterization of Rehabilitation Services (Duncan, Hoenig, Samsa, & Hamilton 1997), Institutes of Medicine Model (1997), ICIDH-2 draft (1997), and the ICF (2002.) The field scan reveals a range of acceptance of AT as part of the performance models.

Field Scan 12
Name: History of Assistive Technology Outcomes
Short Description: This field scan was identified and added to place AT outcomes measurement methodology in context. This literature review provides a chronology of events and publications relevant to assistive technology outcomes. This field scan is available as a report with a chronological event wall chart.
Interim Report: FS12 Update
Technical report: History of AT Outcomes
Field Scan 13
Name: Methods to Identify Assistive Technology Device Use
Short Description: This field scan was added as an outgrowth of the recognition that any AT outcomes system must know what devices and services were provided and how the devices were used. In any outcomes study these would be the independent variables. This scan has examined the assistive technology outcome instruments and AT outcomes research literature to see how the field has historically performed this function. The results of the field scan indicate that current approaches to identify AT use do not necessarily ensure that all devices used by an individual are identified or the method only a priori scrutinizes one subset of devices. Presented at RESNA, June 2003.
Interim Report: FS13 Update
Technical report: Methods to Identify Assistive Technology Device Use
Field Scan 14
Name: Review of the Literature on AT Satisfaction Measurement
Short Description: This field scan was added to the ATOMS Project in the spring of 2003. Recent interest in using product satisfaction scales prompted a review of how product satisfaction is viewed from a research and measurement perspective. While it has consumer perspective in mind, the quantification of self-satisfaction also poses other measurement issues as potential limitations. This field scans reviews the advantages and disadvantages of product satisfaction scales. An article for a refereed journal submission is in progress.

Literature review and survey

Field Scan 3
Name: Outcome Measures Used in AT Research & Development
Short Description: Activity Questions: Do assistive technology device developers use appropriate outcomes instruments and methodologies for their projects? How severe is the problem? Do product developers perceive there to be a problem?

This field scan examined 1) the current use of outcomes measures by Federally funded (2001) investigators of assistive technology and 2) the use and perception of outcomes measures by commercial developers of AT. Presented at RESNA, June 2003. An article for a refereed journal submission is in press.

Summarizing issues of legal/policy

Field Scan 9
Name: Legal Implications of Assistive Technology Outcomes Instruments

Short Description: This field scan examined legal & ethical issues related to AT outcomes systems. Our team attorney has completed this review discussing legal, responsible, & ethical data collection procedures; potential legal ramifications of AT outcomes data (positive and negative); and implications of AT outcomes for policy-making. An open forum discussed these issues and strategies at the RESNA 2003 conference. An article for a refereed journal submission is in progress.

Summarizing newer methodologies and instrumentation

Field Scan 4
Name: Next Generation Data Collection Technology
Short Description: This field scan reviewed current and developing hand held computer data collection technologies that might be relevant to an outcomes system. The review of current and emerging technology approaches was completed based on: a) Content/outcomes, b) Equipment (hardware/software) characteristics, c) Portability, d) Cost, e) Durability, f) Scaling potentials, g) Data collection processes/protocol, h) Data handling protocols, and i) Data Reporting. Presented at RESNA, June 2003
Interim Report: FS4 Update
Technical report: Next Generation Data Collection
Field Scan 5
Name: Comparison of Cost Outcome Methods
Short Description: This field scan reviewed cost the cost comparison literature and explored how various approaches and methodologies might meet the needs for AT outcomes measurement procedures that include cost variables. Results have been published in the Assistive Technology, (2003), 15(1), 16-27.
Interim Report: FS5 Update
Technical report: Comparison of Cost Outcome Methods
Field Scan 6
Name: Use of Multi-attribute (MAU) and Bayes Approaches in Outcomes Data Collection
Short Description: This field scan has reviewed the literature using Multi-attribute Utility (MAU) Theory and Bayes Theorem to identify the scope in which they are used and recommends potential applications relevant to AT outcomes. Articles have been coded into three categories: 1) health, 2) engineering, and 3) general literature.
Technical report: Multiattribute Utility Theory
