Objective: To develop and psychometrically evaluate an information literacy (IL) self-efficacy survey and an IL knowledge test. Methods: In this test-retest reliability study, a 25-item IL self-efficacy survey and a 50-item IL knowledge test were developed and administered to a convenience sample of 53 chiropractic students. Item analyses were performed on all questions. Results: The IL self-efficacy survey demonstrated good reliability (test-retest correlation ¼ 0.81) and good/very good internal consistency (mean j ¼ .56 and Cronbach's a ¼ .92). A total of 25 questions with the best item analysis characteristics were chosen from the 50-item IL knowledge test, resulting in a 25-item IL knowledge test that demonstrated good reliability (test-retest correlation ¼ 0.87), very good internal consistency (mean j ¼ .69, KR20 ¼ 0.85), and good item discrimination (mean point-biserial ¼ 0.48).Conclusions: This study resulted in the development of three instruments: a 25-item IL self-efficacy survey, a 50-item IL knowledge test, and a 25-item IL knowledge test. The information literacy self-efficacy survey and the 25-item version of the information literacy knowledge test have shown preliminary evidence of adequate reliability and validity to justify continuing study with these instruments.
