Job roles of assistive technology service providers in the United States.
The purpose of this study was to identify empirically the roles of assistive technology service providers in the United States. Via factor analysis, the following six job roles were identified: (a) Device Selection and Maintenance Activities, (b) Environmental Modification Activities, (c) Dissemination of Information on Assistive Technology Activities, (d) Evaluation of Suitability of Assistive Device Activities, (e) Administration Activities, and (f) Product Development Activities. The identified roles can provide a potential guide for the development of education or training curricula for assistive technology service providers. Those job role categories can be considered to be required areas of knowledge in a curriculum for assistive technology specialists. The identified roles can also be utilized to help define the profession of assistive technology. That definition could help guide the development of eligibility criterion and examination content for a credentialing programme for qualified assistive technology service providers in the future. A clear description of the job of assistive technology service providers can help administrators create needed positions within service delivery organizations such as state department of rehabilitation services and a rehabilitation hospital. The results could be valuable to the administrators responsible for setting job role criteria for assistive technology service providers. Such criteria are necessary for making effective hiring and employee evaluation decisions. In addition, the results can provide other professionals who utilize assistive technology services with an accurate picture of the services available from assistive technology service providers. When professionals on a rehabilitation team know what to expect of each other, clients are better served. Thus a better understanding of the roles of assistive technology service providers can contribute to better utilization of their services by a multidisciplinary team. This would in turn increase the chances of assistive technology services being offered to clients. Replication of the present study is encouraged to verify the obtained results. A future study should also focus on examining the roles of assistive technology service providers by directly observing their daily work activities. The task inventory used in the present study (ATTI) might be utilized to help guide such observations.
