Understanding User Experience and Acceptance Statistics

I am still busy with my literature review of the mobile learning research that has been published over the past 5 years. One aspect that strikes me after scanning over 200 papers is the high number of user acceptance or user experience studies that use simple questionnaires with likert scales. 

While some of the studies use questionnaires that are based on standardised models such as UTAM, the vast majority uses hand crafted questionnaires without an underpinning model. Without such a model it is hard to understand the real meaning of the results, because in most cases the items that were asked are unique to the study. So the critical question is: how do we interpret the results of these studies in order to gain a better understanding of our domain?
