There were 221 responses received, representing 12% of the population. However, it was necessary to remove 48 questionnaires because of the selection of identical options on the answer scale and outliers.3 The final sample was composed of 173 questionnaires. The data collection for this study occurred from November 2012 to January 2013. Table 2 shows the sample characteristics.
As 51% of users on sample were originated from Information Technology sector, Student's t-test was used to evaluate if there were statistical difference between the response average on IT users and non-IT users (Hair et al., 2010). The results indicated no significant difference among the groups of users.
