Investigation of the Validity Evidence of the Information Literacy Self-Efficacy Scale (ILSES) Among Undergraduate Students

Abstract

The purpose of this research was to provide validity evidence for the Information Literacy Self-Efficacy Scale (ILSES), a widely used instrument that was constructed in 2006. The researchers were interested in investigating the validity of this instrument due to the evolution of the information environment that has taken place since the scale’s original development, mostly as a result of the prominence of the internet. Data were collected from undergraduate students participating in a broader information literacy research study (n = 253). Data were subjected to descriptive analyses, internal consistency reliability, and a confirmatory factor analysis (CFA). After evaluating three different CFA models based on the ILSES’ construction, the researchers determined that a four-factor model fit the data with the following latent constructs: 1) Initiating the search strategy, 2) Assessing and comprehending the information, 3) Interpreting, synthesizing, and using the information, and 4) Evaluating the product and process. A discussion of these findings is provided in light of the evolving information environments in which undergraduate students are expected to use information for their academic, personal, and professional lives.
