Reliability and Validity of a Libqual Scale: A Case of a Private University in Kenya

Abstract

This study focusses on assessing the reliability, validity and dimensionality of LibQUAL scale in a private university in Kenya, a developing country. It also investigates the perception of the library users towards the services provided. This research used the survey method for collecting data from users of the Library. Library service quality was measured by using 22 items taken directly from the 2004 version of the LibQUAL scale. Altogether, 361 questionnaires were distributed and 254 completed questionnaires were used in the final analysis. Cronbach’s Alpha values of each construct confirmed that a good reliability exists with the data. Principle component analysis was employed to determine the important factors of LibQUAL scale. Out of the 22 factors, only 16 were found to satisfy requirements for testing reliability and validity. As a result, a modified LibQUAL was adopted for further analysis. Three service quality components were identified through the exploratory and confirmatory factor analysis as in line with other studies. The three were: affect of service, information control and library as a place. A structural equation model was developed showing the relationships between the three components and library service quality and all the three were significant.
