Workplace Violence Scale
Also known as: WVS
The Workplace Violence Scale measures employee exposure to physical and verbal violence, threats, and harassment in occupational settings. Developed by the International Labour Organization, it captures the prevalence and severity of violent incidents affecting worker safety and health across sectors including healthcare, education, retail, and social services. The scale is essential for identifying organizational violence risk and monitoring workplace safety interventions.
Key highlights
- Directly addresses a critical occupational health hazard with proven links to physical injury, PTSD, burnout, and absenteeism
- Available in sector-specific versions (healthcare, education, social services), allowing contextually relevant assessment
- Simple, self-administered format requiring no specialized training for respondents
- Generates actionable organizational data for violence prevention planning and resource allocation
- International validation across multiple countries and occupational sectors

When to use it
The WVS is essential in sectors with documented high violence risk: healthcare (nurses, physicians, mental health professionals), education (teachers in high-stress settings), social services (case workers, protective services), retail and hospitality (customer-facing roles), and security. Use at organizational baseline assessments, post-incident investigations, before and after violence prevention program implementation, and in periodic occupational health surveillance. Suitable for all adults in paid or unpaid work; populations with prior trauma may require modified administration or follow-up support.
Strengths & limitations
- Directly addresses a critical occupational health hazard with proven links to physical injury, PTSD, burnout, and absenteeism
- Available in sector-specific versions (healthcare, education, social services), allowing contextually relevant assessment
- Simple, self-administered format requiring no specialized training for respondents
- Generates actionable organizational data for violence prevention planning and resource allocation
- International validation across multiple countries and occupational sectors
- Self-report bias; workers may underreport violence due to shame, fear of retaliation, or organizational culture normalizing aggression
- Recall bias for incidents in distant past; shorter recall windows (e.g., past 12 months) improve accuracy but miss chronic low-level harassment
- Cultural and linguistic variation in understanding 'violence' (e.g., physical contact vs. verbal aggression) may affect cross-cultural comparability
- No universal scoring standard; different organizations and research teams use different versions and thresholds, limiting benchmarking
- Does not capture perpetrator information, context (customer vs. colleague vs. supervisor), or worker response/coping, limiting targeted intervention design

Frequently asked
What counts as 'workplace violence' on this scale?
The WVS typically includes: verbal abuse (insults, yelling, threats, sexual harassment), intimidation (threatening gestures, property damage), physical assault (hitting, pushing, weapons use), and in some versions, bullying or deliberate humiliation. The threshold is exposure to unwanted aggression; disagreement or conflict alone is not coded as violence unless it involves threats or force.
How do I use this scale if my workplace doesn't have written incident reports?
The WVS is self-administered and requires no prior documentation; workers report their own experiences directly in the questionnaire. This captures both reported and unreported incidents, making it valuable in cultures or organizations where formal reporting is low. However, cross-check with available incident data post-administration to validate reporting patterns.
Can I compare my organization's scores to other organizations?
Direct comparison requires that both organizations use the same WVS version, recall period (e.g., past 12 months), and similar occupational roles. The ILO and sector-specific research provide reference benchmarks for healthcare (~30–50% annual verbal abuse) and social services (~40–60%); your organization's rate relative to sector norms is more meaningful than absolute scores. Consider hiring an occupational epidemiologist or consultant for formal benchmarking.
What should I do if a worker reports serious violence, like a recent assault?
Administer the scale with sensitivity; allow workers to decline or skip items if distressed. For workers disclosing recent violence, follow your organization's incident response protocol: provide immediate support (first aid, counseling referral), document formally as an incident (separate from the research scale response), and review with occupational health and security. The scale should not replace formal incident reporting or worker protection.
