The predictive validity of computer aptitude, as measured by four aptitude subtests on the Computer Aptitude, Literacy, and Interest Profile and two computer anxiety instruments (the Computer Anxiety Scale and the Computer Anxiety Factor), was investigated using non programming computer performance as the criterion variable. The effects of computer anxiety on performance were inconsistent, and the suggestion is made that computer anxiety may be related to computer experience. The effects of computer aptitude on performance also yielded inconsistent results. The relationship between computer anxiety and computer aptitude varied. The reliability of the instruments is also reported.
