Outcome measures
Primary outcome
The primary study parameter is the physiological arousal which will be measured by the E4 wristband from Empatica. This is an instrument that, while worn on the wrist, records skin conductance, continuous heart rate and skin temperature. The various physiological data will be combined to one overall measure for physiological arousal. During the measurement, participants listen to an audio recording of an individualized script that is based on their most exciting memory of exposing their genitals.
Secondary outcome
In cooperation with police and judicial authorities, after a follow-up period of one and five years, it will be attempted to query information about new police contacts for all participants. This concerns new arrest with regard to sexually offensive behavior and in particular indecent exposure.
Study objective
Within the forensic mental health services, a demand exists for the development of focused interventions and/or guidelines for the treatment of specific criminogenic factors. For sex offenders, deviant sexual arousal is such a criminogenic factor. This study will examine whether the intervention Eye Movement Desensitization and Reprocessing (EMDR) is effective in reducing deviant sexual arousal in men who expose their genitals.
The following hypotheses are formulated:
1) it is expected that EMDR treatment of exhibitionists, according to the addiction protocol by Hornsveld and Markus (2014), will lead to a decrease of physiological arousal, activated by a deviant script, within four sessions.
2) It is expected that this decrease of physiological arousal will be larger in comparison with a control group, which receives four individual sessions of cognitive behavioral therapy, targeting deviant sexual arousal.
3) It is expected that the differences between the two groups will persist at a follow-up measurement eight weeks later.
4) In the long run (1-5 years), it is expected that the group of exhibitionists who were treated with EMDR, will have encountered less police contacts due to indecent exposure, than the control group.
Study design
Measurements will be carried out before the first treatment session, after the last treatment session, and after a follow-up period of eight weeks.
Intervention
One group receives four EMDR sessions. Another group receives four sessions of cognitive behavioral therapy. Both treatments are specifically directed towards the deviant sexual arousal. Both treatment conditions include a fifth concluding session.
