Beyond search and communication: Development and validation of the Internet Self-efficacy Scale (ISS)

摘要

Internet self-efficacy is a pivotal construct for understanding a wide range of online activities. Human activity has been developing in new directions along with the evolution of the Internet over the last few decades. A self-efficacy measure which might appropriately reflect these changes is still lacking in the literature. To address this research gap, the current study developed the Internet Self-efficacy Scale (ISS) and tested its validity and reliability. A sample of 349 undergraduate students completed an assessment battery including the ISS. A 17-item five-factor model was extracted from an EFA. Using a CFA, the 17-item five-factor model obtained from the EFA was cross-validated and the results revealed acceptable model fits where χ2(df = 107) = 198.987, NFI = .918, CFI = .960, and RMESA = .067 (95% C.I.; 052, .081). Also, the ISS showed good convergent validity, evidenced by the significant relationships with Internet outcome expectancy and Internet anxiety.
