Background: A well-known technique to assess (psychological) arousal is to measure the skin conductance level (SCL). Although widely used in experimental psychological research, this technique has not been used often in (locked) psychiatric admission settings on patients who are at a high risk of engaging in aggressive behaviour. One of the obvious reasons for this is that measuring skin conductance, until recently, required a substantial amount of equipment. Methods: As technology developed, it became possible to develop small wearable devices in the form of regular watches to measure the SCL as well as other psycho-physiological parameters. To illustrate the potential this may have for the prevention of aggressive behaviour, a case description is provided of a patient in crisis who became physically aggressive while wearing a skin conductance measurement device. Results: Interestingly, the SCL of the patient had been rising sharply before the first signs of aggressive behaviour were visible. Conclusion: Although it concerns an anecdotal case study, this finding suggests that measuring SCL on a continuous basis in patients who are at a high risk of becoming violent, without this procedure having to interfere with their daily life, may open new avenues for preventing aggression at an earlier stage. A large-scale empirical study in a substantial number of (potentially aggressive) patients is needed, however, to investigate the predictive validity of mobile skin conductance assessments on imminent inpatient aggression in a reliable way.
