Questions Addressed
1. What identifies an individual as “Intimate Terrorist” (IT) and what has research found about Johnson’s assertion that IT’s are almost all men?
2. What are Dyadic Concordance Types and what percent of couples are in each of IT (Male-Only, Female-Only, and Both IT)?
3. What are the implications of the results for:• Conceptualization and Measurement Of Intimate Terrorism
and Johnson’s typology• Theories explaining partner violence (PV)• Prevention and Treatment of partner violence
Intimate Terrorism, One Of Four Types
• Intimate Terrorism (IT) enacts violence to take general control over one’s partner• Situational Couple Violence (SCV) is violence that arises in the context of specific
conflicts and does not involve coercive control• Mutual Violent Control involves both partners engaging in Intimate Terrorist
violence• Violent Resistance uses violence to resist IT
• Professional interest has been mainly on IT and SCV These are the focus of this paper

Summary Of Results Of Six Studies
• Only one found a higher percent of men IT than women• Two found no difference, and reported only percent for combined sample• Two found a larger percent of women than men IT• One did not analyze the data for women
Overall: These six studies suggest that IT by women occurs as often as by men. More studies being added to table. Pattern seems to be the same
Related problem: Johnson’s four types do not include a separate category for female terrorists• Dyadic Concordance Types (discussed next) provide that

Dyadic Concordance Types (DCTs)A Method of Identifying A Crucial Characteristic Of Couples
Can Increase Understanding Of Intimate Terrorism And All Other Relationship Problems
DCTs classify couples into three categories~Male-Only, ~Female-Only ~Both engaged in the behavior of
interest, such as assault or ITDCTs go beyond comparing men and women:
• Provide a couple-level measure that is also gender-specificDCTs are easy to determine if there is “dyadic data” on the behavior of interest,
i.e., behavior measured for both partners• If IT is measured for both:
oCross-classify the IT measure for each partner oResulting four cells identify the three DCTs & reference Neither

Summary Of Results On The 3 Questions
1. What percent of partners are “Intimate Terrorists” as measured by Johnson’s methods?
* 5% of men and 9% of women (as reported by each gender) * More women than men are IT in this study and most other studies
2. What Is the level of Concordance Between partners in Intimate Terrorism?* High: When there was IT in a relationship, in 51% of those couples both
were IT* Sole-perpetrators were: Male-Only 16%, Female-Only 33%* Above percentages hold regardless of whether men or women provided
the data3. What are the implications? Next slides
Implications For Validity Of Widely Accepted Distinction Between Intimate Terrorist And Situational Couple Violence
One reason widely accepted: Seems to resolve 35 year controversy over gender symmetry in perpetration and whether the predominant cause is “patriarchy”
But does not because:o Studies found symmetry in IT, not just in SCVo Permits holding on to belief that PV is predominantly a male crime caused
by patriarchy because, according to Johnson (2006), IT is perpetrated almost exclusively by men
15
16
Other Problems With Conceptualization and MeasurementOf Intimate Terrorism
Insufficiently multidimensional because does not take into account dimensions such as chronicity and severity of assault and injury
(Perhaps reflecting Johnson belief the crucial issue is coercion and that “…the frequency and severity of the violence has no bearing whatsoever on whether the violence is classified as IT” (Johnson, 008 p. 94).)
Label “terrorist” implies chronic assaults, severe assaults, and injury, but not measured to identify IT. Therefore • low “sensitivity” i.e., ability to identify cases that fit the image • Low “specificity” i.e., false positives
Inadequate specification of coercion. Johnson argues that a key characteristic of IT is generalized coercion not situational coercion to get the partner to do or to stop a specific behavior (Johnson, 1995). The measures used by Johnson and others do not adequately distinguishes generalized coercion from situational coercion.
Although Johnson’s method of measuring IT can be applied to women• The four types do not include a separate category for female terrorists
Categorizes most cases as Common Couple Violence, which is implied to not be serious problem
The Reality Behind The Miracle Cure
Does not end the controversy because most studies that empirically compared men and women find similar percentages of male and female IT
Downplays the importance of SCV. But from a public health perspective, SCV is extremely important because• Affects many more couples• Produces the most injuries, physical and psychological because it exposes the
most people to risk of injury• Is a contagious disease and infects the next generation
Diverts attention from the need to protect women by attending to violence by reducing violence by women and their social and psychological problems
Has not improved treatment. In current Batterer Intervention Programs, all offenders get the same intervention
Although Johnson typology identifies important variations in PV, it contuse the controversy over whether the most important cause is “patriarchy” because the typology assumes that only men are terrorists
17
19
THEORETICAL IMPLICATIONRevise theories of PV to recognizes that dyadic nature of PV, including:
• About the same percent of women as men physically assault a partner• Most cases are bi-directional and involve an escalation pattern and a relationship
problem, not just a male problem• 17 studies found only a small percent of acts in self-defense, and no study found
a higher percent than men (Straus, 2012)
IMPLICATIONS FOR PREVENTION AND TREATMENTPrevention programs: Replace programs directed to men and boys with programs
explicitly addressed explicitly to both gendersTreatment of partner violence: Replace the assumption that it is violent men who
need treatment with:• Initial screening to determine whether it is unilateral or mutual,• Base treatment on that evidence, not male-only perpetrator assumption• Provide treatment for both where both perpetrated (half of couples)
Victim services: Continue to give priority to women victims because women are injured more, physically, psychologically, & economically

Does not end the controversy because studies of clinical samples show high rates of female assault (e.g. Gondolf 60%, Giles Sims etc.. See my article, And contrary to his claim, high freq of severe assault in general population.
o Minimizes symmetrical perpetration of most partner violence by giving them a more socially acceptable label ”Situational Couple Violence”
o Asserts the important problem is Intimate Terrorism, not Situational Couple Violence.

type of socially undesirable behavior is associated with willingness to disclose other types)• Nation in which data was collected There are important differences between
nations in the prevalence of crime. National differences in crime, include DCT are analyzed elsewhere (cite??). The focus of this study is whether there are effects of DCT that are in addition to the national context effects.

ObjectivesThe objectives of this study are to: (1) Describe the use of
“Dyadic Concordance Types” (DCTs) as a means of better understanding the concept of “Intimate Terrorist” and identification of cases. (2) Provide empirical estimates for a large sample of dating relationships among university students, of the percent of cases in each of the three DCTs: Male-Only, Female-Only, and Both-Intimate Terrorists. (3) Examine the degree to which each type is associated with physical injury, and gender differences in injury. (4) Evaluate the theoretical basis and empirical adequacy of Johnson's assertion that IT is perpetrated almost entirely by men.

bidirectionalor mutual partner abuse. These results on how prevalent it is for both partnersin a relationship to assault, important as that is, fails to deal with the half ofaggressive relationships in which the aggression is unidirectional. For that half, asshown in this article, many studies have found similar percentages in which only themale partner aggresses and only the female partner aggresses. It is crucial that thisbe taken into account in research, theory, and practice about PA. Identifying bidirectionalcases does not do that. Thus, even when results on bidirectional abuse arereported, a serious gap persists because information on these two DCTs is crucial fortheories of partner abuse and for prevention and treatment, including efforts to endviolence against women
Provide example showing difference between same rate for men and women and Both. It is in IPS descriptive article and I think in the PASK article.
29
Just how easy it is to obtain data on DCTs
is illustrated by an analysis of the 1975 National Family Violence Survey. In this study, as in most other studies on partner abuse, only one partner was interviewed. Nevertheless, the DCTs could be determinedbecause the partner interviewed was asked about both their own behavior and thattheir partner. It required only a cross tabulation of assault by the male partner bythe assault by the female partner. The percentages in the resulting four cells werethe three DCTs and the no-assault group. Among the relationships in which there wasan assault, the percentages were 25% Male-Only, 27% Female-Only, and 48% Both-Assaulted (Straus, 1980; Straus, Gelles, & Steinmetz, 2006). I did not name this asDCTs or give the typology any name at all.

35
Recognizing that female partners also assault and that about the same percent of women as men assault was a major advance, with extensive research, but one not yet the basis for theory and practice.
Recognizing mutual violence is a further major advance with small but growing amount of research, and also not yet the basis for theory and practice. It has been consistently found that mutually violent relationships experience more violence, more severe violence, and higher rates of injury (Gray and Foshee 1997; Swahn et al. 2010). Whitaker, Straus and Gozjolko
Recognizing DCTs has just begun.
36
DCTs and APIM
Cousins share some of the same genes
Need to spend more time together
Dyadic analysis is a much broader concept than Dyadic Concordance Types. DCTs are only one specific tool to aid dyadic analysis. The fact that DCTs deal with only a small part of what is implied by dyadic analysis is not only a limitation but also an advantage. The advantage is that it gives scholars and practitioners a specific and easily applied tool to aid making the dyadic nature of partner abuse part of their research, theorizing, or prevention and treatment work.
use of DCTs as an aid to investigating and theorizing about partner abuse and in preventing and treating partner abuse.
