There is a rich body VPN

There is a rich body of literature in social psychologythat provides a solid base for research in predictingbehaviour in a variety of domains. MIS researchers havein recent years devoted increased attention to selfe� cacy construct to better understand why people use asystem or how successful the usage might be (Venkateshand Davis 1996, Marakas et al. 1998, Compeau et al.1999, Torkzadeh et al. 1999).In order to measure dimensions of Internet selfe� cacy, we reviewed the literature on informationprocessing and self-e� cacy (Hurphreys and Revelle1984, Murphy et al. 1989, Harrison and Rainer 1992,Torkzadeh and Koufteros 1994, Compeau and Higgins1995) and generated a list of 24 items. Then ®vepractitioners and four academics were consulted toreview these items. The wording for a few items werealtered based on their input. A ®ve-point Likert-typescale was used where 1 is strongly disagree to 5 isstrongly agree. The survey was administered to MISundergraduates at a state university in the Southwestregion of the United States. Students in several sectionsof information system courses participated in the study.Participation in the study was voluntary. A total of 277(51% male, 49% female) participated in the study. Theage of the participants ranged from 17 to 57 with a meanof 24.88.The questionnaire responses were explored withseveral objectives in mindÐpuri®cation, unidimensionality, reliability, brevity and simplicity of factor structure. First, we wanted to purify the items before doingfactor analysis. The need to purify the items (i.e.eliminate `garbage items' ) that are suggested as measures
