Reactance, a specific type of resistance aroused when a threat to freedom occurs, has been identified as a potential culprit in inhibiting effective law enforcement interactions (includes information gathering and interviews of victims, witnesses and suspects). Law enforcement interactions are critically important, but law enforcement officers (LEOs) often unknowingly arouse reactance during them, resulting in less effective or even negative interactions. The impact of linguistics on reactance is well studied across several disciples, but law enforcement is not one of them. The critical importance of the linguistic composition of a message is not disputed in the literature, but law enforcement agencies are not currently applying this existing research. Give that reactance is one of the most common underlying causes of resistance, a systematic literature review across disciplines was conducted and WIRES (Words Impacting Reactance: Evidence-based Strategies) Level I Training was developed. The first part of the current study aims to evaluate if this training is valid (does it increase knowledge about reactance and linguistic strategies to avoid/mitigate it). For the second part of the study law enforcement officers will be asked to apply the concepts presented in the WIRES Level I training while in the field. Data will be collected on call outcomes as well as officer perception of the WIRES techniques when used in the field.
