The following items comprise a research instrument, which is a first step toward identification of factors associated with workplace violence reported in the clinical-empirical literature. The items are not exhaustive, fixed or mutually exclusive, and the entire checklist should be considered a work-in-progress. The checklist is meant for an interdisciplinary audience such as administrative supervisors, human resources managers, vocational counselors, and mental health personnel. Readers are cautioned that a simple sum of risk factors and the use of specific cutoffs do not equate to varying degrees of risk. The presence of one or two factors may suggest high risk of workplace violence. Generally, some form of previous threatened, attempted or consummated violence to others, self or property must be present to reasonably predict future violence. Finally, the final summary ratings are judgments by assessors, which may lead to a referral for comprehensive assessment and intervention, if appropriate.
Scoring Instructions
(To be utilized after examiner is familiar with program and
manual)
STEP 1.
Check if basal violence is present. One or more of the following must be endorsed:
____ Previous
threatened, attempted, or consummated violence
towards others.
____ Past use or
threatened use of weapons outside work.
____ Previous damage
or destruction of work-related property.
____ Previous direct
or veiled threats to harm other employees.
____ Stalking,
including repeated harassment, of other
employees.
____ Threats of
suicide or homicide.
Predict no violence will occur
if none of the above are checked. In this case,
there is no need to refer the case for a
comprehensive forensic assessment unless you are
unsure as to whether historical violence has
occurred. If uncertain, you should have
individuals other than the predictee fill out
the WVRAC, and compare responses. In addition,
you may want to assess for unreported violence
(see Chapter 4 in Hall, H.V., & Pritchard, D.
(2002). Workplace Violence Risk Analysis:
Effective Prediction and Intervention
Strategies. Kamuela, HI: The Pacific
Institute for the Study of Conflict and
Aggression).
STEP 2.
Check to see how many items from
each category of the WVRAC are present (History, Recent Events, Work Attitudes
and Traits, and Organizational Deficiencies).
If two items are checked from
each category on the WVRAC (a total of at least
eight items), you have reasonable grounds for
referring this person for a comprehensive risk
analysis. You should refer this individual for
further evaluation because the employee may be
"HOT" for violence (i.e., has history,
opportunity, and
triggers associated with violence). The
empirical basis for this conclusion is contained in Hall,
H.V., & Ebert, R. (2002). Violence
Prediction: Guidelines for the Forensic Practitioner,
Second Edition. Springfield, IL: Charles C.
Thomas Publisher.
STEP 3.
All other persons may or may not
be referred, depending on individual
circumstances. The presence of historical factors
is required if the case is referred (see Step
1). There is an association between number of
factors present and the possibility of acting
out. The more items checked on the WVRAC, the
greater the likelihood of violence to others.
Generally, scores above 10 (with
at least one history item) may be referred for
further evaluation. Previous analysis
has shown that almost all violent employees have
scores above 10. Note that some items have point
values greater than 1, which are added to the
total in order to determine whether the score
exceeds 10.
