Psychometric analysis of Integrated Digital Library User Success (IDLUS) Scale in academic digital library environment

What is it about?

This study executes confirmatory factor analysis (CFA) in structural equation modeling (SEM), to investigate the reliability and validity of the proposed integrated digital library user success (IDLUS) scale in academic digital library computing information system in the area of information management and systems. We analyzed 355 valid responses (M.Phil. and Ph.D.) from the largest and oldest public sector university in Pakistan. Sample selection was calculated through stratified random sampling technique from the four faculties of University of the Punjab. The instrument was constructs based from the available two digital library and information system success models. First model is Jung’s (1997) digital library user success model that is further composed of flow model (1977), end user computing satisfaction (EUCS) model (1987), and Joshi’s overall user satisfaction model (1990). Similarly the second model is DeLone & McLean’s reformulated information system success (2003) theory. The question items employed a 5-point Likert scale and executed regression weights, standardized regression weights, convergent validity, variance extracted, construct reliability, and discriminant validity to infer results. The findings show that IDLUS scale has the excellent validity and reliability estimates.
