This paper describes the development and validation of a new 40-item Internet Attitude Scale (IAS), a one-dimensional inventory for measuring the Internet attitudes. The first experiment initiated a generic Internet attitude questionnaire, ensured construct validity, and examined factorial validity and reliability. The second experiment further analyzed the results of the first experiment to verify criterion validity and reliability using a different sample group. The results of the first and second experiments illustrated that this newly Internet Attitude Scale is a valid and reliable instrument for measuring Internet attitudes.
