The Multi-dimensional Privacy Scale for Internet Users (MPS-I) was developed for the multidimensional assessment of concerns about information privacy, and its validity and reliability were examined. In Study 1, a web-based survey was conducted with 1,036 Internet users. Factor analysis of responses to the scale revealed four dimensions of concerns about one's information privacy: Autobiographical Information (11 items), Demographical Information (8 items), Identifiable Information (4 items), and Password and Credit Information (3 items). In Study 2, 119 undergraduates completed a paper-based questionnaire, and the relationships of the MPS-I to privacy preferences and self-disclosure tendencies were examined. The results suggested that the MPS-I had sufficient validity and was highly reliable.
