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.
