Does the intervention modify attitudes toward gender roles and sexual harassment?
Researchers will compare the three experimental groups to evaluate the effects of IVR:
- Identity Exchange Group with Exposure to Sexual Harassment: Participants embodied their partner's identity in a VR harassment scenario.
- Identity Exchange Group without Harassment Exposure: Participants embodied their partner's identity in a neutral VR scenario.
- Third-person Observer Group: Participants observe a harassment scenario in VR from their own perspective.
Participants will:
- Attend one virtual reality session in a laboratory setting.
- Undergo pre- and post-intervention assessments and a three-month follow-up.
- Complete self-report questionnaires and physiological measures (eye tracking and pupillometry).
- Participate in semi-structured interviews about their experiences. This study aims to explore how immersive VR embodiment can be used as a tool for gender violence prevention by fostering perspective-taking and behavioral change.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
REVISE - Virtual Reality Gender-Swap with Harassment ExposureBehavioural
Participants will embody a virtual avatar of their female partner in a sexual harassment scenario using full-body tracking, and identity exchange in virtual reality (VR). The goal is to assess whether experiencing harassment from a first-person perspective increases empathy and decreases tolerance toward sexual harassment.
REVISE - Virtual Reality Gender-Swap without HarassmentBehavioural
Participants will embody a virtual avatar of their female partner in a neutral social interaction scenario using VR-based identity exchange. This condition controls for the effect of perspective-taking alone, without exposure to harassment, to evaluate its impact on empathy and gender attitudes.
| Study group | Role | What they receive |
|---|---|---|
| Identity Exchange with Exposure to Sexual Harassment | Experimental | Participants will experience a virtual reality (VR) perspective-taking intervention in which they embody their female partner's avatar in a scenario depicting sexual harassment. This immersive experience aims to enhance empathy and reduce the acceptance of sexual harassment. Physiological responses (eye tracking and pupillometry) will be recorded, and participants will complete pre- and post-intervention self-reports. Receives: Behavioral: REVISE - Virtual Reality Gender-Swap with Harassment Exposure |
| Identity Exchange without Harassment Exposure | Experimental | Participants will embody their female partner's avatar in a neutral VR scenario without any harassment. This condition serves to evaluate the effects of identity exchange alone, without exposure to gender-based violence, on empathy and gender attitudes. Pre- and post-intervention assessments and physiological measures will be collected. Receives: Behavioral: REVISE - Virtual Reality Gender-Swap without Harassment |
| Third-Person Observer Condition | No intervention | Participants will observe a VR scenario depicting sexual harassment from a third-person perspective, without experiencing identity exchange. This condition acts as a control to determine whether passive observation differs from immersive perspective-taking in modifying attitudes toward gender-based violence. Self-reports and physiological responses will be also analyzed. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Empathy Scores (Interpersonal Reactivity Index - IRI)
Empathy will be assessed using the Interpersonal Reactivity Index (IRI), a validated self-report measure that evaluates different components of empathy, including perspective-taking and empathic concern. The IRI consists of 28 items, each rated on a 5-point Likert scale (0 = Does not describe me well to 4 = Describes me very well). The total score ranged from 0 to 112, with higher scores indicating greater levels of empathy. Cronbach's alpha ranged from .68 to .80. Participants will complete the IRI at baseline (pre-intervention), immediately post-intervention, and at a three-month follow-up to assess changes over time. Higher scores indicate greater empathy levels.
Measured: Baseline, immediately post-intervention, 3-month follow-up
Secondary outcomes (10)
Change in Gender Role Attitudes (Ambivalent Sexism Inventory - ASI)
Gender role attitudes will be measured using the Ambivalent Sexism Inventory (ASI), which assesses two factors: hostile and benevolent sexism. We will use the brief version composed of 12 items (6 items in each factor) with Cronbach's alphas of .75 and .81. Higher scores indicate greater sexist attitudes. Participants will complete the ASI at baseline, post-intervention, and 3-month follow-up to evaluate changes in gender-related beliefs.
Measured: Baseline, immediately post-intervention, 3-month follow-up
Change in Communication Patterns (Communication Patterns Questionnaire - CPQ)
Communication patterns in close relationships will be assessed using the Spanish version of the Communication Patterns Questionnaire (CPQ). The CPQ is a self-report measure that evaluates three dimensions of communication: mutual constructive communication, communication avoidance or demand/withdrawal, and aggressive communication. Participants will complete the CPQ at baseline (pre-intervention), immediately post-intervention, and at a three-month follow-up to assess changes in communication styles over time. The questionnaire consists of 24 items, each rated on a 9-point Likert scale ranging from 1 ("Very unlikely") to 9 ("Very likely"). Higher scores indicate greater use of the corresponding communication strategy. Cronbach alpha in Spain ranged from .62 to .84.
Measured: Baseline, immediately post-intervention, 3-month follow-up
Change in Relationship Satisfaction (Dyadic Adjustment Scale - DAS)
We will use the Spanish brief version of the DAS. It is composed of 13 items answered in a variable Likert scale and those items are grouped under three second order factors and one of first order structure. The scale in its short form presents a cut-off of 44. The higher the score the best adjustment is observed. Cronbach alpha was .83.
Measured: Baseline, immediately post-intervention, 3-month follow-up
Change in Couple Flourishing (Couple Flourishing Measure - CFM)
Couple flourishing will be assessed using the Couple Flourishing Measure (CFM), a unidimensional self-report instrument. The Spanish validated version by Saavedra-Roa et al. will be used in this study. Participants will complete the CFM at baseline (pre-intervention), immediately post-intervention, and at a three-month follow-up to assess changes in relationship satisfaction and flourishing over time. The questionnaire consists of 16 items, each rated on a 7-point visual analogue Likert scale ranging from 1 (Distressed relationship), 4 (Satisfied relationship), to 7 (Flourishing relationship). The total score ranges from 16 to 112, with higher scores indicating greater couple flourishing. The instrument demonstrated high internal consistency reliability (α = .94).
Measured: Baseline, immediately post-intervention, 3-month follow-up
Change in Acceptance of Modern Myths about Sexual Aggression (AMMSA Scale)
Attitudes towards modern myths about sexual aggression will be assessed using the Acceptance of Modern Myths about Sexual Aggression Scale (AMMSA; Gerger et al., 2007). The Spanish adapted and validated version (Megías et al., 2011) will be used in this study. The AMMSA is a self-report measure designed to evaluate subtle beliefs that justify or minimize sexual aggression. Participants will complete the AMMSA at baseline (pre-intervention), immediately post-intervention, and at a three-month follow-up to assess changes in the acceptance of sexual aggression myths over time. The questionnaire consists of 30 items, each rated on a 7-point Likert scale, ranging from 1 ("Totally disagree") to 7 ("Totally agree"). Higher scores indicate greater acceptance of modern myths about sexual aggression. Cronbach alpha in a Spanish sample was .91.
Measured: Baseline, immediately post-intervention, 3-month follow-up
Change in Body Ownership Illusion
Body ownership illusion will be assessed to measure the extent to which participants experience the illusion of embodying their self-avatar and their partner's avatar. This measure evaluates embodiment and agency from a first-person perspective during the VR experience. A validated four-item scale will be administered verbally in two phases: (1) mirror embodiment with the assistant and (2) farewell with the assistant . In the first phase, the assistant will instruct the participant to look into a virtual mirror and ask: "On a scale from 0 to 10, to what extent did you feel that the virtual body in the mirror was your own?" and "When looking down, did you feel that the virtual body was yours?" In the second phase, the assistant will ask: "Did you feel that you owned a different body?" and "Did you feel fear of aggression?" Higher scores indicate a stronger experience of embodiment.
Measured: During VR exposure at two assessment points: (1) Mirror embodiment phase (approximately 5 minutes after VR start) and (2) Farewell phase (at the end of VR exposure, approximately 15 minutes after VR start).
Change in Physiological Arousal (Pupillometry)
Physiological arousal will be measured using pupillometry, which records minute fluctuations in the pupil diameter in response to stimuli. Pupil dilation is an indicator of autonomic nervous system activation, and greater pupil dilation is associated with negative emotional processing. The key metric recorded will be pupil diameter ratio (measured in millimeters): the relative change in pupil size in response to VR stimuli. The pupil data will be sampled at a minimum frequency of 60 Hz with a visual angle accuracy of 0.5°. Artifacts such as pupil amplitude outliers (<1 mm or >9 mm), drifts, and blinks will be coded as missing values. A 10 Hz low-pass filter will be applied to smooth the data.
Measured: From the start of VR exposure until the completion of the VR session (approximately 15 minutes). Data will be collected in real-time during this period.
Change in Visual Attention (Eye-Tracking Data)
Visual attention will be assessed using eye tracking technology integrated into VR goggles. Eye tracking measures fixation behavior as an indicator of attention allocation toward erotic stimuli, based on sexual objectification theory (Hollett et al., 2022). Two key parameters will be recorded: 1) fixation count (measured in number of fixations): number of available fixations on a specified area of interest (VR model's neckline) and dwell time (measured in milliseconds), and total duration of fixations on the area of interest (neckline). Fixation was defined as a continuous gaze lasting at least 100 ms.
Measured: From the start of VR exposure until the completion of the VR session (approximately 15 minutes). Data will be collected in real-time during this period.
Changes in affective responses
Self-Assessment Manikin (SAM) will be used to assess participants' affective responses during the intervention. This is a non-verbal, pictorial scale that evaluates three dimensions of emotional reaction: Valence (from negative/unpleasant to positive/pleasant), Arousal (from calm to excited), and Dominance (from feeling dominated to feeling in control). Each dimension is rated on a 9-point scale: 1 indicates the lowest intensity (e.g., unpleasant, calm, or dominated), and 9 indicates the highest intensity (e.g., pleasant, excited, or dominant). Higher scores represent more positive emotional valence, higher arousal, and greater sense of control or dominance
Measured: During VR exposure at one assessment point: Farewell phase (at the end of VR exposure, approximately 15 minutes after VR start).
Qualitative Insights from Participant Experience
Participants will complete semi-structured interviews post-intervention to explore their experiences and perceptions of the VR embodiment task. Interviews will be transcribed and analyzed using thematic analysis to identify key themes related to empathy, gender role reflection, and perceived impact of the intervention.
Measured: Immediately post-intervention

The goal of this clinical trial is to evaluate the effectiveness of REVISE (REalidad Virtual Inmersiva y SExualidad), an immersive virtual reality (IVR) intervention designed to promote empathy and reduce sexual harassment behaviors in heterosexual cisgender men.
The main questions that this study aims to answer are as follows.
Does experiencing gender swapping in IVR increase empathy towards survivors of sexual harassment?
Does the intervention modify attitudes toward gender roles and sexual harassment?
Researchers will compare the three experimental groups to evaluate the effects of IVR:
- Identity Exchange Group with Exposure to Sexual Harassment: Participants embodied their partner's identity in a VR harassment scenario.
- Identity Exchange Group without Harassment Exposure: Participants embodied their partner's identity in a neutral VR scenario.
- Third-person Observer Group: Participants observe a harassment scenario in VR from their own perspective.
Participants will:
- Attend one virtual reality session in a laboratory setting.
- Undergo pre- and post-intervention assessments and a three-month follow-up.
- Complete self-report questionnaires and physiological measures (eye tracking and pupillometry).
- Participate in semi-structured interviews about their experiences. This study aims to explore how immersive VR embodiment can be used as a tool for gender violence prevention by fostering perspective-taking and behavioral change.

- Model description
- Participants will be randomly assigned to one of three independent intervention groups: 1. Identity Exchange with Exposure to Sexual Harassment: Male participants will embody their female partner's avatar in a VR harassment scenario. 2. Identity Exchange without Harassment Exposure: Male participants will embody their female partner's avatar in a neutral VR scenario. 3. Third-person Observer Condition: Male participants will observe a harassment scenario in VR without identity exchange. Each participant remains in their assigned condition throughout the study, and comparisons are made between groups based on empathy, gender attitudes, and harassment-related responses.
| Arm | Type | Receives |
|---|---|---|
| Identity Exchange with Exposure to Sexual Harassment | Experimental | Behavioral: REVISE - Virtual Reality Gender-Swap with Harassment ExposureParticipants will experience a virtual reality (VR) perspective-taking intervention in which they embody their female partner's avatar in a scenario depicting sexual harassment. This immersive experience aims to enhance empathy and reduce the acceptance of sexual harassment. Physiological responses (eye tracking and pupillometry) will be recorded, and participants will complete pre- and post-intervention self-reports. |
| Identity Exchange without Harassment Exposure | Experimental | Behavioral: REVISE - Virtual Reality Gender-Swap without HarassmentParticipants will embody their female partner's avatar in a neutral VR scenario without any harassment. This condition serves to evaluate the effects of identity exchange alone, without exposure to gender-based violence, on empathy and gender attitudes. Pre- and post-intervention assessments and physiological measures will be collected. |
| Third-Person Observer Condition | No intervention | –Participants will observe a VR scenario depicting sexual harassment from a third-person perspective, without experiencing identity exchange. This condition acts as a control to determine whether passive observation differs from immersive perspective-taking in modifying attitudes toward gender-based violence. Self-reports and physiological responses will be also analyzed. |

Interventions
| Intervention | Type | Arms |
|---|---|---|
| REVISE - Virtual Reality Gender-Swap with Harassment ExposureParticipants will embody a virtual avatar of their female partner in a sexual harassment scenario using full-body tracking, and identity exchange in virtual reality (VR). The goal is to assess whether experiencing harassment from a first-person perspective increases empathy and decreases tolerance toward sexual harassment. | Behavioural | Identity Exchange with Exposure to Sexual Harassment |
| REVISE - Virtual Reality Gender-Swap without HarassmentParticipants will embody a virtual avatar of their female partner in a neutral social interaction scenario using VR-based identity exchange. This condition controls for the effect of perspective-taking alone, without exposure to harassment, to evaluate its impact on empathy and gender attitudes. | Behavioural | Identity Exchange without Harassment Exposure |
Primary outcome
Change in Empathy Scores (Interpersonal Reactivity Index - IRI)
Time frame: Baseline, immediately post-intervention, 3-month follow-up
Empathy will be assessed using the Interpersonal Reactivity Index (IRI), a validated self-report measure that evaluates different components of empathy, including perspective-taking and empathic concern. The IRI consists of 28 items, each rated on a 5-point Likert scale (0 = Does not describe me well to 4 = Describes me very well). The total score ranged from 0 to 112, with higher scores indicating greater levels of empathy. Cronbach's alpha ranged from .68 to .80. Participants will complete the IRI at baseline (pre-intervention), immediately post-intervention, and at a three-month follow-up to assess changes over time. Higher scores indicate greater empathy levels.
