For the purposes of this study data from more than 10,000 library users from 14 institutions that implemented randomized control trials during the spring 2008, fall 2008, and spring 2009 survey cycles were analyzed. Findings indicate that LibQUAL+® Lite is a viable and preferred alternative to the long form of 22 core items that has been established since 2003. LibQUAL+® Lite uses item sampling methods to: (a) gather data on all 22 LibQUAL+® core items, while (b) each individual participant responds to only a subset of items. Every Lite user responds to one “linking” item from each of the subscales, and to a randomly-selected subset of five items from the remaining 19 (22-3) core LibQUAL+® items. As a consequence, survey response times are roughly cut in half, while the library still receives data on every survey question. The matrix sampling method, the randomized control trial framework, and the statistical analysis methods outlined in the current study are useful heuristic methods for other high stakes library survey implementations whether for a physical as well as a digital library environment. These methodological approaches add rigor and thoughtful perspectives as they inform ways libraries shape their services and “touch” their users through improvements and innovations in the years to come. text http://hdl.handle.net/2142/14570 Copyright 2009 Martha Kyrillidou Library & Information Science 1992 Library & Information Science 0370 University of Illinois at Urbana-Champaign Dissertation Ph.D. PHD:Library & Infor Sci -UIUC 10KS0370PHD
