While clinical DSS have many proven benefits in the medical field, their uptake by GPs has been limited. This research explores the influence of decision styles as a possible explanatory variable for the usage of DSS. Insight into the reasons why GPs do not use clinical DSS will allow the development of strategies to facilitate more widespread adoption with consequent improvements across many areas. Depth interviews were conducted with 37 GPs comprising a mix of education backgrounds, experience and gender. In addition respondents completed a decisions styles questionnaire. Results indicated that users of DSS were more likely to have an integrative decision style while non users adopted a flexible decision style. Decision style was also strongly correlated to education with overseas trained doctors more likely to have integrative decision styles and Australian trained GPs exhibiting flexible styles.
