Expert decision support system use, disuse, and misuse: a study using the theory of planned behavior

This empirical study used theory of planned behavior to formulate hypotheses about the use, disuse, and misuse of an expert system decision support (EDSS) technology. It was found that EDSS use was negatively related to errors, whereas misuse of EDSS was positively related to errors. More positive attitudes and social influences led to increased EDSS use, while perceptions of control had no apparent effect. The interaction of social influences and attitudes had a significant non-linear relationship with EDSS misuse.
