Technology acceptance research within the field of information systems has been limited in its application to health and there is a concurrent need to develop and gain empirical support for models of technology acceptance within health and to examine and address acceptance and utilisation issues amongst health professionals to improve the success of information system implementation in this arena. There is a paucity of information relating to acceptance and utilisation of ICT amongst occupational therapists, yet it is vital that this unique group of professionals are aptly prepared to accept new technologies that will ultimately be introduced in their work places and through their involvement with clients. This research addresses these issues by examining ICT acceptance and utilisation by Australian occupational therapists. The objective of this study was to understand the factors contributing to occupational therapists' acceptance of ICT and to develop and empirically validate a model of ICT acceptance amongst this group of health professionals.
A three-phase study design was undertaken to collect substantial quantitative, qualitative and longitudinal data on technology acceptance and use amongst occupational therapists. Phase r consisted of the development of a research model of ICT acceptance; questionnaire development and pre-testing; and, conducting focus groups to obtain qualitative data. A non-experimental survey research design was utilised in phase II, involving a national survey sent to over 6,500 Australian occupational therapists to provide cross-sectional data on behavioural intention and acceptance of ICT. Phase III was a naturalistic inquiry, involving a longitudinal multi-method field study to apply the research model to a small, non-profit community-based healthcare organisation, providing both quantitative and qualitative longitudinal data on actual usage and acceptance of ICT.
Key findings from this study include.
\U+2022\ Occupational therapists harbour positive attitudes towards ICT but are frustrated by inadequate access to technologies they believe have the potential to add much value to their work.
\U+2022\ Occupational therapists make good use of the ICT they are given access to, using technology for a variety of clinical, administrative and professional purposes. Given the opportunity, they are apt to be creative and innovative with their use of ICT.
\U+2022\ The primary outcome of this study aimed to be the development and validation of a model of technology acceptance behaviour by occupational therapists. The research model was primarily based on the Unified Theory of Acceptance and Use of Technology (UTAUT) (Venkatesh, Morris, Davis, & Davis, 2003) and Chau and Hu's (2002) three technology acceptance dimensions.
\U+2022\ Results from the structural equation modelling analysis of 1605 survey responses suggested the research model explained almost two-thirds (63.6%) of the variance in occupational therapists' acceptance of ICT. The rich data gathered in the case study supported the research model and the role of all model variables in influencing technology acceptance and use.
\U+2022\ The degree of compatibility of ICT to the existing work practices, values, needs and experiences of occupational therapists was shown to exhibit the strongest total effect on intention to use technology.
\U+2022\ Insights from this research led to the development of a comprehensive model of individual technology acceptance and use - the Technology Acceptance and Use model (TAUM). The TAUM extends the focus of the original research model to examine continued use of ICT.
\U+2022\ The need to extend technology acceptance studies to post-acceptance use and to examine the resultant organisational outcomes from acceptance and use is captured in the proposed Technology Acceptance and Outcomes Framework (TAOF). The framework links technology acceptance to the realisation of organisational benefits, organisational outcomes and the impacts of technology use.
This study makes several important contributions to the technology acceptance, health informatics and occupational therapy literature. The theoretical significance of this work derives from the thoroughly constructed research model, the unique approach to the study of technology acceptance and the findings which were comprehensive both in scope and detail, derived from one of the largest sample sizes ever tested.
The study is unique in that the technology acceptance model was developed to be independent of individual user group, technology type and implementation context. Whereas technology acceptance models are usually tested in one specific environment/context, amongst a population of users who derive from that context and for a specific technology - this model was tested across potentially thousands of contexts and applies to a generic conceptualisation of technology. This is the first study to adopt three such significant shifts in the study of technology acceptance.
The study findings highlight the complexity of the constructs and relationships that influence technology acceptance and outcomes and confirms the limitations of current models at understanding and describing this complexity. The study serves as an opportunity to reconceptualise models of technology acceptance and the impacts of acceptance and use; and serves as a source of new insights into the field. The results of this study have practical and theoretical implications for employers/governments, healthcare professionals, educators, information system professionals and information system researchers.
