Article history:Received 12 February 2016Revised 31 October 2016Accepted 23 November 2016Keywords: Computer tool AnxietyCue reactivity Chemically dependentBackground and objective: Anxiety is one of the major inﬂuences on the dropout of relapse and treat- ment of substance abuse treatment. Chemically dependent individuals need (CDI) to be aware of their emotional state in situations of risk during their treatment. Many patients do not agree with the di- agnosis of the therapist when considering them vulnerable to environmental stimuli related to drugs. This research presents a cue reactivity detection tool based on a device acquiring physiological signals connected to personal computer. Depending on the variations of the emotional state of the drug addict, alteration of the physiological signals will be detected by the computer tool (CT) which will modify the displayed virtual sets without intervention of the therapist.Methods: Developed in 3ds Max® software, the CT is composed of scenarios and objects that are in the habit of marijuana and cocaine dependent individual’s daily life. The interaction with the environment is accomplished using a Human-Computer Interface (HCI) that converts incoming physiological signals indicating anxiety state into commands that change the scenes. Anxiety was characterized by the average variability from cardiac and respiratory rate of 30 volunteers submitted stress environment situations. To evaluate the effectiveness of cue reactivity a total of 50 volunteers who were marijuana, cocaine or both dependent were accompanied.Results: Prior to CT, the results demonstrated a poor correlation between the therapists’ predictions and those of the chemically dependent individuals. After exposure to the CT, there was a signiﬁcant increase of 73% in awareness of the risks of relapse.Conclusion: We conﬁrmed the hypothesis that the CT, controlled only by physiological signals, increases the perception of vulnerability to risk situations of individuals with dependence on marijuana, cocaine or both.© 2016 Elsevier Ireland Ltd.
