DOMESTIC VIOLENCE INVENTORY PRE-POST SCALE INTERPRETATION
There are several levels of DVI Pre-Post interpretation, ranging from viewing the
DVI Pre-Post as a self-report, to interpreting scale elevations and scale
inter-relationships. The following table is a starting point for interpreting
DVI Pre-Post scale scores.

A problem is not identified until a scale score is at the 70th percentile or
higher. Elevated scale scores refer to percentile scores that are at or above
the 70th percentile. Severe problems are identified by scale scores at or above
the 90th percentile. Severe problems represent the highest 11 percent of
offenders evaluated with the DVI Pre-Post.
Scale Interpretation
1. Truthfulness Scale: Measures how truthful the offender was while
completing the test. It identifies guarded and defensive people who attempt to
"fake good". Scores, at or below the 89th percentile, mean that all, DVI Pre-Post
scales are accurate. Scale scores in the 70 to 89th percentile range are
accurate, because they have been Truth-Corrected. Scores at or above the 90th
percentile mean that all DVI Pre-Post scales are inaccurate (invalid), because
the offender was overly guarded, read things into test items that aren't there,
was minimizing problems, or was attempting to fake answers. Respondents with
reading impairments might also score in this 90-100th percentile scoring range.
If not consciously deceptive, offenders with elevated Truthfulness Scale scores
are uncooperative, fail to understand test items, or have a need to appear in a
good light. The Truthfulness Scale score is important, because it shows
whether or not the offender answered DVI Pre-Post test items honestly.
Truthfulness Scale scores at or below the 89th percentile indicate that all
other DVI Pre-Post scale scores are accurate. One of the first things to check,
when reviewing a DVI Pre-Post report, is the Truthfulness Scale score. The
Truthfulness Scale can be interpreted independently. The Truthfulness Scale
overrides all other DVI Pre-Post scale scores.
The DVI Pre-Post Truth-Correction procedure resembles that used in the
Minnesota Multiphasic Personality Inventory (MMPI). Scale item responses are
totaled (to yield raw scores), and truth-correction is then, applied. Domestic
violence offender risk, for each DVI Pre-Post scale, is determined by a series of
questions that culminate in each scales risk. This enables matching of problem
severity and treatment intensity.
2. Violence (Lethality) Scale: Identifies offenders who are dangerous
to themselves and others. It is defined as the expression of rage and hostility,
through physical force. Violence is aggression in its most extreme, and
unacceptable form. Elevated scorers can be demanding, sensitive to perceived
criticism, and are insightless about how they express their anger/hostility.
Severe problem scorers should not be ignored, as they are threatening, very
dangerous, and at risk. A particularly unstable and perilous situation, involves
an elevated Violence Scale, with an elevated Alcohol Scale or Drug Scale score.
The higher the elevation is of these scale scores (e.g., Severe Problem range), with
the Violence Scale - the worse the prognosis. An elevated Stress
Management Scale, with an elevated Violence Scale score, provides insight
regarding codeterminants, and possible treatment recommendations. An elevated
Control Scale, in combination with an elevated Violence Scale score, suggests a
rigidly, hostile characterological pattern. Loss of control results in punitive
consequences, whereas, lack of control is anxiety inducing. The Violence Scale
score can be interpreted independently, or in combination with other DVI
Pre-Post scale scores.
3. Control Scale: "Control" is a complex psychological term. Some
researchers are interested in the dynamics of controlling others. The DVI
Pre-Post Control Scale measures one's need to control others. In social
psychology, control is often a synonym for power or influence. Within the
context of domestic violence, control refers to the process of regulating,
restraining, or controlling others. These controlling behaviors vary from normal
(mild) to pathological (severe). Control-related, behavior pathology focuses on
exaggerated, distorted, or extreme behaviors like swearing, pushing,
intimidating, hitting, and even battering. Without getting into a discussion of
a variety of control theories, the construct "control" has become important in
understanding domestic violence. The significance of control is reflected in
domestic violence perpetrators' difficulties in giving up control and their
resistance to treatment.
An elevated (70 to 89th percentile) Control Scale score indicates the presence
of regulating, restraining, and controlling behaviors. Scores in the severe
problem (90 to 100th percentile) range identify extreme and, even, pathological
controlling behaviors. Elevated Control Scale scorers have a need to control
others. Anything that interferes with this sense of control is frustrating and
can be threatening. These people often have a lot of friction or conflict in
their relationships.
An elevated Control Scale score, with an elevated Violence Scale score, is
usually a malignant sign. The height of these scale scores is important. Scores
in the severe problem (90 to 100th percentile) range should not be ignored as
they are indicative of a dangerous person. Similarly, an elevated substance
(Alcohol or Drug Scale) abuse score, in conjunction with an elevated Control
Scale score, is problematic. Alcohol and/or drug involvement can exacerbate
control issues. An elevated Stress Management Scale score with an
elevated Control Scale score, may help in understanding the offender's
situation. A person who doesn't handle stress well is likely to experience
symptom magnification. In summary, the Control Scale can be interpreted
independently, or in conjunction with other DVI Pre-Post scale scores.
4. Alcohol Scale: Measures alcohol use and the severity of abuse.
Alcohol refers to beer, wine, and other liquor. An elevated (70 to 89th
percentile) Alcohol Scale score is indicative of an emerging drinking problem.
An Alcohol Scale score in the severe problem (90 to 100th percentile) range
identifies serious drinking problems.
In intervention and treatment settings, the offender's Alcohol Scale score helps
staff work through the offender's denial. Most people accept the objective and
standardized Alcohol Scale score as accurate and relevant, in comparison to a
person's subjective opinion. This is particularly true when it is explained
that elevated scores don't occur by chance. The offender must answer a definite
pattern of alcohol-related admissions, for elevated scores to occur. And, scale
scores are based on thousands of offenders' scores, who have completed the DVI
Pre-Post.
An elevated Alcohol Scale score in conjunction with other elevated scores
magnifies the severity of the other elevated scores. For example, if you have an
offender with an elevated Violence Scale, who also has an elevated Alcohol Scale
score, that person is even more dangerous when drinking. In summary, the
Alcohol Scale can be interpreted independently, or in conjunction with other
elevated scores.
5. Drug Scale: Measures illicit drug use and the severity of abuse.
Drugs refer to marijuana, cocaine, crack, ice, amphetamines, ecstasy, barbiturates, and
heroin. These are illicit substances. Prescription drug abusers (licit
substances) are also identified with the DVI Pre-Post Drug Scale. An elevated
(70 to 89th percentile) Drug Scale score is indicative of an emerging drug
problem. A Drug Scale score in the severe problem (90 to 100th percentile)
range identifies serious illicit and prescription drug abusers.
In intervention and treatment settings, the offender's Drug Scale score helps
staff work through client denial. And, an elevated Drug Scale score, in
conjunction with other elevated scale scores, magnifies the severity of the
other elevated scores. For example, an elevated Violence Scale, in conjunction
with an elevated Drug Scale score, increases the severity and risk associated
with the Violence Scale. In summary, the Drug Scale can be interpreted
independently, or in conjunction with other elevated scales.
6. Stress Management Scale: Measures how well the offender manages
stress. It is now known that stress exacerbates symptoms of mental and
emotional problems. Thus, an elevated Stress Management Scale score, in
conjunction with other elevated, DVI Pre-Post Scale scores, helps explain the
offender's situation. For example, when a person doesn't handle stress well,
other existing problems are exacerbated. This problem augmentation applies to
substance (alcohol and other drugs) abuse, violence (lethality), control issues,
and stress-related problems.
An elevated Stress Management Scale score can also exacerbate emotional and
mental health symptomatology. When a Stress Management Scale score is in the
severe problem (90 to 100th percentile) range, it is likely that the offender
has a diagnosable, mental health problem. In these instances, referral to a
certified/licensed mental health professional may be appropriate, to obtain a
diagnosis, prognosis, and treatment plan. Lower elevated scores suggest less
intensive referral alternatives, like a stress management program. In summary,
the Stress Management Scale can be interpreted independently, or in conjunction
with other elevated scales.
At one sitting, of approximately 30 minutes duration, staff can acquire a vast
amount of domestic violence, perpetrator information, which includes acting out
(violence) propensity, controlling tendencies, substance abuse, and stress
management skills. Early problem identification facilitates timely intervention
and improved outcome results.
