Forensic psychology lies at the intersection of criminal justice and mental health care (Vollm et al., 2018). Its main goal is to reduce the chance of recidivism and address treatment targets in relation to offence-related factors and psychiatric disorders (Kip et al., 2018;Vollm et al., 2018). The forensic population is characterised by various risk factors for recidivism, such as high psychiatric comorbidity (Fazel & Danesh, 2002;Van der Veeken et al., 2018), relatively low treatment motivation (Drieschner & Boomsma, 2008;Kip et al., 2019b) and low cognitive abilities (Kip et al., 2019b). The combination of these risk factors makes the forensic population both hard to reach and difficult to treat, which is reflected in high reoffending rates (Bengtson et al., 2019). As risk factors are diverse, the use of individualised therapy is essential for treatment efficacy (Bonta & Andrews, 2007). Implementing technology in treatment can support individualised therapy (Kip et al., 2019b). Furthermore, when applied in the right way, technology could reduce bias and increase inclusivity. Therefore, technologies could enhance the forensic field in the main elements of care: risk assessment, offender rehabilitation, and reintegration (Bonta & Andrews, 2007;Vollm et al., 2018). Two forms of eHealth with the potential for application with a forensic population include Virtual Reality (VR) and applications for mobile devices ("smartphone apps"). Both are discussed in this chapter.VR has several features that can make it a valuable addition to the forensic psychology toolkit. In this chapter, we focus on immersive VR (also referred to as IVR) which is generally experienced through a head-mounted display (HMD) (Fox et al., 2009). For research and assessment purposes VR provides advantages over current methods. Among others, VR enables objective data gathering and standardised treatment, resulting in less biased and more individualised assessment. Consider roleplay exercises, which generally take place with real actors. Confederates or trained actors' verbal and non-verbal behaviour may cause unintentional variation in the treatment and they may vary in terms of
