Use of Information and Communication technology in healthcare (eHealth) is growing rapidly in both developing and developed countries. It is important that the healthcare institutions and the communities assess their preparedness for implementing eHealth, to enhance their chances of success. eHealth readiness assessment tools can help in determining such preparedness of healthcare institutions. This study is part of a larger study that develops and validates eHealth readiness assessment tools for healthcare institutions in developing countries. The study used survey methodology to determine the internal consistency reliability of eHealth readiness assessment tools. A total of fourteen healthcare institutions were selected in two areas of Pakistan, and all the managers and healthcare providers in these institutions, who had experience with eHealth programs, were asked to complete the tools. In total, 50 managers and 48 healthcare providers completed the survey. Cronbach’s alpha score for the tool for managers was 0.94, and for the tool for healthcare providers was 0.91. Also, the Cronbach’s alpha score for each category was found to be greater than 0.81. All the items, in both the tools, revealed significant correlation with the mean scores for that category. Thus the study showed significant internal consistency for both the e-readiness assessment tools. eHealth readiness assessment tools, tested in this study, demonstrated reasonable internal consistency reliability. These results, along with the face and content validities, reported in another study, provide confidence to the planners of eHealth programs to use these tools as part of the planning process.
