A Structural Equation Model of Information Retrieval Skills

要旨

Identifying factors that influence information retrieval skills can help us to understand search behavior and show what skills are required to conduct efficient and accurate searches. This paper describes a study in which relationship factors that influence the information retrieval skills of a cohort of 1,551 Japanese Internet users are investigated using a combination of survey methods, factor analysis, and structural equation modeling. Our factor analysis confirms the importance of three sub-skill groups that are similar to sub-skill groups that have been previously reported (i.e., formal Internet skills, operational skills, and assessment skills) and indicates the importance of a fourth group (which we call "search strategy skills"). Our structural equation model incorporates two novel factors that have not previously been studied in this context: critical thinking ability, and self-efficacy for the Internet and information retrieval. The results show that critical thinking ability and self-efficacy positively influence the information retrieval skill level, and age is found to be a negative influence. Contrary to previously reported results, little independent effect is seen from educational attainment.
