e-GovQual: A multiple-item scale for assessing e-government service quality Xenia Papadomichelaki 1 , Gregoris Mentzas National Technical University of Athens, 10682, Athens, Greece abstract article info Available online 25 September 2011 Keywords: e-Government Service Quality Measurement Instrument A critical element in the evolution of governmental services through the internet is the development of sites that better serve the citizens' needs. To deliver superior service quality, we must rst understand how citi- zens perceive and evaluate online. Citizen assessment is built on dening quality, identifying underlying di- mensions, and conceptualizing measurements of these e-government services. In this article an e-gov service quality model (e-GovQual) is conceptualized and then a multiple-item scale for measuring e-gov service quality of governmental sites where citizens seek either information or service, is developed, rened, validat- ed conrmed and tested. © 2011 Elsevier Inc.

Nevertheless, different quality dimensions have been proposed and there is no con- sensus on the component dimensions. Collectively, the extant litera- ture suggests that e-service quality is a multidimensional construct although the content of what constitutes e-service quality varies across studies (Zeithaml, Parasuraman, & Malhorta, 2002). While early in the development of e-government services, issues of accessibility were troubling and while some issues do remain, there is a new awareness raised by scholars like Bertot and Jaeger (2006). While the literature is not as robust as we would like to see, the authors believe this manuscript will begin to provide a conceptual foundation examining what is necessary for determining quality of e-government services. The provision of such a study will further enhance the e-government's ability to exploit and further attract more citizens to make their transactions through the web. The objective of this study is to develop and validate an instru- ment to measure citizens' perceptions of service quality from e- government sites or portals. Throughout this article we describe the development, renement, psychometric evaluation, potential appli- cations and limitations of a multiple-item scale (e-GovQual) for mea- suring e-government service quality of governmental sites, where citizens seek either information or service. As already noticed by Aladwani and Palvia (2002) there are three generic steps common in all models' construction and verication that include (1) conceptu- alization, (2) design, and (3) normalization. In the rst step a model is conceptualized after an extensive literature survey. The second step focuses on construct validity and reliability analysis. In this step the rening of the sample of items takes placein order to come up with an initial scaledeciding on such operational issues as question types and question sequence. The third and last step concerns the effort to normalize the scale that has been developed. It involves the important steps of subsequent independent verication and valida- tion. In our research's rst step, conceptualization, after an extensive literature review as provided in Section 22, we classied 33 e- government quality attributes under six main quality dimensions: Ease of Use, Trust, Functionality of the Interaction Environment, Reliability, Content and Appearance of Information, and Citizen Support. After creat- ing the conceptual model we needed to conrm whether the quality indicators selected describe the construct of e-government service quality. As a next step, a questionnaire based on these criteria was designed to elicit and assess information on preferences of the citi- zens when evaluating e-government service and governmental web- sites. The scale was produced following guidelines for measurement development proposed by Churchill (1979). In order to rene and evaluate the scale to measure e-government quality we collected 630 responses via an online survey that took place from February to June of 2007. We rened the scale, tested its reliability, and looked for a stable factor structure that resulted in 21 quality attributes clas- sied under four quality dimensions: Reliability, Efciency, Citizen Support and Trust (e-GovQual). A second online survey with 264 respondents took place from November 2007 to February 2008 in order to verify, validate, and nally to conrm the scale. This instru- ment developed under the above process would be valuable to researchers and practitioners interested in designing, implementing, and managing governmental websites. The rest of the paper consists of ve sections. The next section reviews prior research related to e-government, e-service quality, website quality, portal quality, and service quality measure- ments; the third section includes the conceptualization of the Government Information Quarterly 29 (2012) 98109 Corresponding author.
