And Buffy, you say this study uses the Conflict Tactics Scale - are you aware that the CTS is considered severely flawed by many researchers in this field, and is mainly used and promoted by people associated with the Men's Rights Movement?
"Gender symmetry [in domestic violence] is often reported in studies employing large, random, and national or community samples and using the Conflict Tactics Scale (CTS), a questionnaire that asks about recent use of specific tactics by an intimate partner against the respondent to measure IPA (Brush, 1990; Cantos, Neidig, & O'Leary, 1994; Johnson, 1995; Morse, 1995). Morse (1995) suggests that the goal is to reconceptualize the social problem of ""woman battering"" to one of ""family violence."" From this perspective, some scholars tend to conclude that men and women are equally likely to be both perpetrators and victims of IPA.
"Several arguments have been made to explain the huge discrepancies in scholars' interpretations of findings regarding women's use of violence against intimate partners. These arguments include criticisms of the CTS as a measure of IPA, concerns over gender differences in reporting of IPA and its impact on abuse rates, the differences due to settings in which the data have been collected and the samples studied and, finally, issues related to studying victimization only versus victimization and perpetration.
"First, and at the heart of much of this criticism, is CTS: a set of scales designed by Strauss and Gelles, leaders in the ""family violence"" approach, to measure IPA (Strauss & Gelles, 1990). Some scholars have harshly criticized the CTS for ignoring the context, motivations, meanings, and consequences of IPA (see, for example, Bachman, 1998; Belknap, 2001; Berk, Berk, Loseke, & Rauma, 1983; DeKeseredy, 1995; Dasgupta , 2001; DesKeseredy & Schwartz, 1998; Dobash & Dobash, 1988; Kurz, 1993; Schwartz, 1987; Stark & Flitcraft, 1983; Yllo, 1983, for critiques). As stated previously, the studies reporting gender symmetry and the higher rates of female-perpetrated IPA predominantly use national sampling plans. These are also the studies most likely to employ the CTS to measure IPA. Thus, it is likely not the ""national"" sample that results in the different rates of female-perpetrated IPA, but rather the strong correlation between a study's likelihood of using the CTS and using a national sampling plan that leads to the reporting of gender symmetry. The use of the CTS clearly explains some of the discrepancies between the two approaches.
"Also, some researchers are concerned that the studies using the Conflict Tactics Scale (CTS) interpret the results incorrectly, and that this may account for the differences in the studies.
Dobash and colleagues report that in many of the studies finding higher rates of female-perpetrated IPA, a respondent who reports that he or she has ever, ""pushed,"" ""grabbed,"" ""shoved,"" ""slapped,"" or ""hit or tried to hit"" another person, is regarded as a perpetrator of IPA (Dobash et al., 1992). This may include only one instance not taken in context. Thus, when victims resist abuse in any way, including defending themselves or their children, they will mistakenly be portrayed as intimate partner abusers. For an excellent review of the history of the CTS, its past, revised, and current uses and limitations, read DeKeseredy and Schwartz (1998).

Sampling bias
"According to Michael Johnson, the CTS’s dependence on voluntary interviews with a representative sample population could create a strong bias against measuring the worse cases of domestic violence: “men who systematically terrorize their wives would hardly be likely to agree to participate in such a survey, and the women whom they beat would probably be terrified at the possibility that their husband might find out that they had answered such questions.
"Jack Stranton points out another important sampling bias: the CTS, as used in the original Straus/Gelles research and most of the research that follows it, excludes violence that occurs after a divorce or separation. However, such violence accounts for 76% of spousal assaults, and is overwhelmingly committed by men; excluding this violence disproportionately omits most spousal violence against women.
Contrary Social Science Data
"Many non-CTS studies have found, contrary to CTS results, that men are overwhelmingly the perpetrators of domestic violence, while women are overwhelmingly the victims. Since most (but not all) of these studies are designed to measure criminal violence, Farrell dismisses them, saying men are socialized to “take it like a man” and not report their victimization. However, Russell Dobash pointed out “that women have their own reasons to be reticent, fearing both the loss of a jailed or alienated husband’s economic support and his vengeance.” Moreover, surveys of domestic violence victims in the US and Canada have found that men are more likely to call the police after being assaulted by their partner. So while it’s true that both men and women have motivation not to report their abuse, it’s just not true that men are actually less likely to report abuse than women.
"A review of the social science literature indicates that the CTS is, even according to its creators, seriously flawed when used as a comparative measure of male and female domestic victimization (i.e., the way men’s righters and anti-feminists use it)."
