Risk perception and adoption of technology: An empirical study of personal computer use for Pakistani managers

Risk associated with use of information technology (IT) may adversely affect the performance of organizational members. In the past, a number of researchers had applied technology acceptance model (TAM) to measure the use of IT, but overlooked the use of personal computers under security threats. The current study presented a modified model of TAM with an additional construct of Perceived Risk (PR). Under the modified model, PR is taken as a direct determinant of attitude toward using computers. A survey of 431 Pakistani managers was conducted through validating questionnaires. SPSS was used for data measurement and regression analysis was done to measure the relationship among the observed constructs. It was found that modified model of TAM works well in the sociocultural environment of Pakistan. PR was found to have a significant relationship with attitude towards using computer and it was concluded that risk factor is reduced when the use of computers is enhanced.
