A group of researchers conducted a study to test the inclusion of attitudes in the Technology Acceptance Model (TAM). Two versions of this model are compared, such as that with attitudes or original model (TAM-O) and without attitudes or revised model (TAM-R). TAM with and without attitudes were applied to the adoption of the student enrolment through three different technologies, such as the Internet, electronic kiosk, and mobile phone. A sample of 1414 undergraduate students was obtained for this study from the University of Seville, Spain. This sample was spread over 26 centers, grouped into four main fields, such as Economics or Law, Humanities, Sciences or Technical Studies, and Biology or Medicine. The sample elements were extracted in proportion to the relative size of each area, with 488 students participating in the first setting or e-service with 56.97% of females and 43.03% of males. The measurement model corresponding to the theoretical relations used for comparison in the three proposed settings was analyzed.
