Chapter 2. Literature Review Adoption, Diffusion and Use of E-government
Hassan Al-Zaabi Services in Abu Dhabi Police Force
On the other hand, Chong et al. (2009) used some of the DOI constructs in Malaysia, which is a
country that Abu Dhabi can be compared with. However, in their study it was found that innovation
attributes have no influence on adoption. Therefore, this study will examine this issue and find out
more about DOI/PCI constructs with respect to influence on e-government adoption in a public sector
organisation in a developing country.
Examining in depth and understanding the current situation in ADPF will help in discovering barriers
or problems and therefore, know how things could be improved. With such reasoning from the
literature it was seen that DOI/PCI will help with understanding more of this topic.
2.7.2 Constructs from TAM
Furthermore, previous e-government research (Carter and Belanger, 2005) found that the
aforementioned factors of DOI are associated with TAM‟s constructs: perceived usefulness and
perceived ease of use (Carter and Belanger, 2005). Additionally, TAM has been used in various studies
that examined adoption in information systems (Carter and Weerakkody, 2008). Therefore, this
research will also combine this model in the theoretical framework, more due to the importance of
understanding user‟s ability towards using the innovation. For example, if they find it useful or not, or
easy to use or not. Furthermore, it was also noticed from the literature review, that factors such as lack
of training led to not using e-services because users may find it difficult to use and none or less training
capabilities are available (Kumar and Best, 2006; Dada, 2006). Therefore, the TAM will also help in
investigating more issues in this research.
2.7.3 Constructs from DTPB
Perceived Behavioural Control (PBC) is a construct in the TPB. The decomposition of PBC, self-
efficacy, resource and technology facilitating conditions was also used in DTPB (Taylor and Todd,
1995b) and TAM3 (Venkatesh and Bala, 2008). Based on literature, it was noticed that PBC is an
important construct that can influence the behavioural intention and actual use (Taylor and Todd,
1995b; Macredie and Mijinyawa, 2011). This research will also use the decomposition of PBC to
examine the following: (i) Self-efficacy; to examine staff in ADPF if they have the confidence and
skills to use the e-services (ii) Resource facilitating conditions; to examine the current situation in
ADPF and its current resources, such as, budgets set for implementation and training purposes (iii)
Technology facilitating conditions; to examine the current IT infrastructure and IT support in ADPF.
