Regarding the order of the Likert scale options, the surveys are set up that way for a couple reasons. The simplest is that regardless of the order, there will likely be a few people who select the wrong option. Given that, there is some evidence that because people read left to right, putting the more positive answer on the left can create a positive bias - people choose the first option they see - which contributes to a false ceiling effect in Likert-scale responses. Putting strongly agree on the right means that people should (theoretically) read through the options. Also, if you think of it numerically, 1 to 5 makes more sense than 5 to 1. This model was designed and tested for the original public library toolkit; the ACRL task force discussed it and opted to keep the format consistent.
