Calculating alcohol risk in a visualization tool for promoting healthy behavior.

Objective: To investigate effective methods for communicating the personalized risks of alcohol consumption, particularly to young people.
Methods: An interactive computerized blood alcohol content calculator was implemented in Flash based on literature findings for effectively communicating risk. Young people were consulted on attitudes to the animation features and visualization techniques used to display personalized risk based on disclosed alcohol consumption.
Results: Preliminary findings reveal the calculator is relatively enjoyable to use for its genre. However, the primary aims of the visualization tool to effectively communicate personalized risk were undermined for some users by technical language. Transparency of risk calculations might further enhance the tool for others. Worryingly, user feedback revealed a tension between accurate presentation of risk and its consequent lack of sensationalism in terms of personal risk to the individual.
Conclusion: Initial findings suggest the tool may provide a relatively engaging vehicle for exploring the link between action choices and risk outcomes. Suggestions for enhancing risk communication include using intelligent techniques for selecting data presentation formats and for demonstrating the effects of sustained risky behavior.
Practice Implications: Effective communication of risk contributes only partially to effecting behavior change; the role of the tool in influencing contributing attitudinal factors is also discussed.
