OBJECTIVES: This article reports the prevalence of two types of interpersonal violence (IPV) (sexual and physical) and one type of aggression (psychological) in three low-to-middle-income Caribbean countries. It examines IPV among adolescents and young adults as both victims and perpetrators.
METHODS: This population-based study compares the experiences of 1530 year olds in countries at different levels of socioeconomic development. The Revised Conflict Tactics Scales (CTS2) and other behavioral instruments were used to assess the level and characteristics of IPV.
RESULTS: Out of 3 401 respondents, 70.9% reported victimization by some form of violence, which was most commonly perpetrated by a relationship partner (62.8%). Sexual violence victimization was reported more commonly by women, and was highest in Jamaica. Significant between-country differences in overall levels of reported physical violence, and psychological aggression, were evident when stratifying by perpetrator type.
CONCLUSIONS: The very high levels of reported IPV indicate very high levels of tolerance among victims, and suggest a culture of violence and of adversarial intimate relationships may be well entrenched. The findings support the view that co-occurrence of general interpersonal violence and partner violence may be limited, and that one may not necessarily be a predictor of the other. They also reveal that, among partners, not only are there no gender differentials in victimization by physical violence, but more women than men are self-reporting as perpetrators of this type of IPV.
Key words: Sexual violence, domestic violence, aggression, adolescent, adult, Barbados, Jamaica, Trinidad and Tobago.
OBJETIVOS: Se informa la prevalencia de dos formas de violencia interpersonal (VIP) la sexual y la física y de un tipo de agresión la psicológica en tres países del Caribe de bajo a mediano ingresos. Se analiza la VIP entre adolescentes y adultos jóvenes, ya sea como víctimas o agresores.
MÉTODOS: En este estudio basado en la población se comparan las experiencias de personas de 15 a 30 años de países con diferentes niveles de desarrollo socioeconómico. Se utilizó la escala revisada de tácticas de conflicto (CTS2) y otros instrumentos de análisis conductual para evaluar el nivel y las características de la VIP.
RESULTADOS: De las 3 401 personas que respondieron, 70,9% informó haber sido víctima de alguna forma de violencia, más frecuentemente ejercida por sus parejas (62,8%). Las mujeres informaron con mayor frecuencia haber sido víctimas de violencia sexual, y esta fue más frecuente en Jamaica. Se encontraron diferencias significativas entre los países en cuanto a la violencia física y la agresión psicológica, que se hicieron notables al estratificar por el tipo de agresor.
CONCLUSIONES: Los muy elevados niveles informados de VIP indican un alto grado de tolerancia entre las víctimas e indican que se puede estar arraigando una cultura de violencia y de relaciones íntimas basadas en el enfrentamiento. Estos resultados confirman que la ocurrencia simultánea de la violencia interpersonal en general y la violencia de pareja puede ser limitada y que una forma no necesariamente es un factor de predicción de la otra. En las parejas no se observaron diferencias en la victimización según el género y más mujeres que hombres se declararon agresoras en esta forma de VIP.

Based on recent studies of violence and injury reporting high and rising rates of morbidity and mortality as well as high associated economic costs, violence and injury must now be seen as a major public health problem (13), especially in the Caribbean (46). In addition, there is growing evidence that the consequences of violence go far beyond immediate morbidity and mortality, comprising longer-term and negative effects on mental and reproductive health as well as general socioeconomic development (1, 79).
Understanding the full burden of -violent behavior in a specific country requires consideration of not only mortality statistics but also morbidity statistics, which are often much higher. In the United States, for example, the estimated ratio of mortality to morbidity ranges from 1:19 to 1:200 (8, 1012). Although reliable morbidity data are not available for the Caribbean region, one study estimates a mortality-to-morbidity ratio range of 1:8 to 1:26 (4). In Jamaica, most admissions to casualty departments and accident and emergency units are related to injury caused by violence, with one-half of admissions resulting from intentional violence on individuals under 30 years of age (13). In Barbados and Trinidad and Tobago, injuries account for 10 25% of hospital admissions (14). In St. Vincent and the Grenadines, there were 17 murders recorded per 100 000, versus 1 257 and 863 per 100 000 for assault and wounding, respectively (15).
Increasing awareness of domestic violence has led to a recent increase in related literature, which reports incidence rates ranging from 16 to 69% (1, 1617). In the Caribbean, there is limited quantitative data on the subject but considerable qualitative evidence that the problem is serious, growing, and widespread (4, 1821). A clearer understanding of the characteristics, prevalence, and causes of interpersonal violence (IPV) and aggression has therefore become critical.
Violence, violent injury, and other health-risky behaviors often begin at a very early age. As in most countries in the Americas (5, 10, 22), violence and injury is now the leading cause of death among adolescents and young adults in the English-speaking Caribbean, with injury as the leading cause of death among 514 year-old males, and homicide and suicide the most important causes of death among the 1524 year age group (4). Partner violence exists among adolescents and young adults (23). In Jamaica, qualitative data suggest that the adolescent partnering process is closely linked to IPV and aggression (24).
Over time, there have been many attempts to explain antisocial behaviors, such as crimes against individuals. Yet, understanding of the magnitude and causes of this type of violence is still inadequate. With respect to the specific problem of domestic violence (including partner violence), there is still no clear consensus or overarching theoretical model to explain the causes of this phenomenon across time and/or space. There is, however, continuing debate about what should be incorporated in the definition of various types of violence, and their respective causes. Given the wide variations of violence in terms of its expressions, rationalizations, and locations, these causes are likely to be complex and multiple (1, 2530).
There are also conflicting views regarding the role of gender in IPV and aggression. Certainly, the feminist movement has been critical in raising awareness of the serious problem of female battery and spurring its incorporation into national health agendas. However, there is increasing recognition of the reality of male victimization and the fact that the " gender gap" (a disproportionate number of female victims versus male victims) may not exist or is narrowing (25, 3033). It is therefore important that analyses of IPV and aggression be gender-differentiated to determine possible differences in incidence rates.
Although current evidence indicates low- and middle-income countries have a disproportionately high rate of IPV and aggression (1), research on the determinants of this type of violence in these countries remains limited (3438). Most existing explanatory models and frameworks were developed in high-income North Atlantic countries. Therefore, their usefulness in low- to middle-income countries needs to be explored, particularly in the Caribbean, where the economic situation, as well as sociocultural mores and practices, may be quite different. Relevant studies conducted in the Caribbean include research on the problem of IPV and aggression in schools and its effect on educational performance and nutrition (34, 3840); the impact of exposure to violence-related psychological distress (37); and the role of protective factors against violence, such as family connectedness (38).
This article provides an initial report of a population-based survey of IPV and aggression among adolescents and young adults (1530 years of age) in three Caribbean countries (Barbados, Jamaica, and Trinidad and Tobago). It includes the reported prevalence of two types of IPV (sexual and physical) and one type of aggression (psychological) experienced by victims, as well as perpetrators. This is the first quantitative, comparative, Caribbean study utilizing the Revised Conflict Tactics Scales (CTS2) and other behavioral instruments to assess the extent and characteristics of IPV and aggression in the region, and collecting information on a range of possible determinants, including education and occupation; family structure and migration patterns; household composition; social support networks; parenting; and psychosocial variables such as perceptions of self-esteem, exclusion, and personal power. The study aims to determine the magnitude of physical and sexual IPV, and psychological aggression,2 as well as the possible role of gender in victimization or perpetration by/of these types of violence. It also investigates differences between violence among partners and violence among acquaintances and strangers.
MATERIALS AND METHODS
All individuals aged 1530 years were eligible for participation in this study. Actual study participants were selected using a three-level cluster-sampling regime (participants within households within communities) based on the standard methodology used by the national statistical office of each participating country. A community was defined as a contiguous group of census enumeration districts (EDs) containing at least 80 households. Communities were stratified using an urban/rural classification. Those that allowed for the best capture of the full range of prevalent socioeconomic conditions, based on standard measures (household density, measured as the number of people in the household divided by the number of bedrooms; number of household possessions; and unemployment rate), were selected for study. Within the selected communities, the EDs with probability proportional to size (PPS) were chosen. Within each selected ED, a random selection of households was visited based on a planned route (with a randomly chosen starting point). One eligible participant from each household was chosen as a representative. If a household contained more than one eligible individual, the study participant was chosen using random selection tables. Study participant selection was then stratified by sex and age to ensure adequate representation of both men and women of all ages.
Based on anecdotal reports about violence in the three countries of study, a level of IPV and aggression of between 30% and 50% was expected. The use of logistic regression to analyze the effect of a single covariate (adjusted for prior covariates) required a sample of at least 409 study participants in each country and resulted in an odds ratio (OR) of 1.75 (IPV/aggressionpositive individuals versus IPV/aggressionnegative individuals) for 90% statistical power and a test significance of 5% (at an IPV prevalence of 30%). This sample size was inflated to account for a survey design effect of 2 and a non-response rate of 20%, providing a final sample size in each country of 982 study participants.
The proportion of study participants (survey respondents) that experienced IPV victimization from strangers or acquaintances was calculated and stratified by country, sex, and type of violence (physical versus sexual). The prevalence of aggression within relationships was calculated using a third category (psychological aggression), with the survey respondent as either victim or perpetrator. Logistic regression models were used to examine the effect of age, sex, and country differences on both IPV and aggression prevalence. All prevalence estimates and regression models were weighted to account for the survey design and levels of non-response. Stata statistical software (Version 10, StataCorp LP, College Station, Texas, USA) was used for all analyses. Although statistical significance was assumed at p < 0.05, all confidence intervals (CIs) and p-values are presented, where appropriate, to clarify the exact strength of statistical relationships.
This study's definition of physical violence is based on the following World Health Organization (WHO) definition of violence: " the intentional use of physical force or power, threatened or actual, against . . . another person, or against a group or community, . . . that either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment or deprivation . . ." (1: 5). The term " interpersonal violence," in this study, refers to violence between family members and intimate partners as well as violence between acquaintances and strangers. Within this IPV category, this study differentiates violence between partners (i.e., within intimate relationships) from violence between persons known to each other (including relativessome of whom could be members of the domestic household) and violence between strangers. Reflecting the realities in the Caribbean and other countries, where relationship partners and nuclear family members do not necessarily co-resideand in contrast to most literature on the subject, which may use the terms " domestic violence" and " partner violence" interchangeablythis study focuses on the personal or relationship context of the violence perpetrated or experienced, as opposed to its venue (and therefore does not use the term " domestic violence" ).
Violence perpetrated by partners. Partner violence was assessed using the Revised Conflict Tactics Scales (CTS2) (41, 42) previously validated in Jamaica. The CTS2, which yields subscale reliability scores ranging from 0.72 to 0.81 (Cronbach's alpha), includes two questions each for 39 different items, resulting in a total of 78 questions comprising five different scales measuring experiences with violence as both victim and perpetrator. These five scales include negotiation, psychological aggression, physical assault, injury, and sexual coercion. In this study, the CTS2 was used to assess the history of involvement in partner IPV as well as different experiences with violenceboth minor and severe. Although the study questions focused on the 12 months preceding the survey, reports of incidents occurring prior to that time period were also recorded. Therefore, the data reported in this article refer to incidents " ever experienced." Incidents were classified by type and severity of violence and by role of respondent (perpetrator, victim, or both).
Violence perpetrated by acquaintances and strangers. Respondents were asked about sexual and physical violence perpetrated against them by strangers as well as persons known to them (not including intimate partners). The questions were developed using the methodology implemented in the Violence Against Women Survey (VAWS) conducted in Canada in 1993 (43) and were tested and validated at the national level in Barbados. This methodology, which allows for analysis of IPV regardless of the gender of the victim or perpetrator, has also been previously used successfully in the Caribbean (22, 44).
Drawing on the two instruments mentioned above, sexual violence (or coercion) was defined as something that occurred when any individual forced or attempted to force the respondent into any sexual activity s/he did not want by threatening, holding down, or hurting the respondent in some way.
Socioeconomic status. While most countries rely on consumption-based measurements to assess socioeconomic status, the use of this type of measure has proven challenging in the Caribbean region. Therefore, in this study, education and occupational status (employment versus unemployment) were used as proxies for socio-economic status. Educational levels were measured by combining two classifying criteria: years of schooling, and type of school last attended (primary, secondary, and tertiary).
Survey response rates are presented in Table 1. There were a total of 3 401 completed questionnaires. More were collected in Jamaica (41% of all completed surveys) than in Barbados or Trinidad and Tobago (29% each in both countries).
Table 2 provides sociodemographic data on the three countries studied, illustrating important differences in terms of gross domestic product (GDP) per capita, GDP annual growth rate, level of urbanization, and migration. The United Nations Development Programme (UNDP) Human Development Index (HDI), a standard tool for measuring and comparing well-being across countries based on life expectancy, literacy, education, and GDP, is used to summarize the development differences between the three countries in this study. Jamaica ranks the lowest in terms of GDP per capita, while Barbados has the highest HDI rating (0.892 on an ascending scale of 0 to 1).
Table 3 provides selected socio-demographic characteristics of the final 3 401 study participants (survey respondents). The distributions for age, sex, ethnicity, educational level, and unemployment were similar to those in the available aggregate national data (13, 4547). Barbados and Jamaica report roughly equivalent ethnic distributions. The Trinidad and Tobago survey respondents were divided equally between East Indian ethnicity and those of African descent. After adjusting for the confounding effect of age, women were more likely to have a higher level of education than men (OR, 1.42; 95% CI, 1.221.65; p < 0.001). Respondents from Barbados were more likely to have a higher level of education than either Jamaica (OR, 3.94; 95% CI, 2.755.63; p < 0.001) or Trinidad and Tobago (OR, 3.28; 95% CI, 2.514.28; p < 0.001). Unemployment was significantly higher among women, who had a 1.77 OR of being unemployed versus men (95% CI, 1.46 2.14). Unemployment was lowest in Trinidad and Tobago and was significantly higher in both Barbados (p < 0.001) and Jamaica (p < 0.001).
IPV among strangers, acquaintances, and partners
Victimization. Table 4 shows the percentage of reported physical violence and sexual coercion against all survey respondents (i.e., as victims), stratified by country of participation, sex of respondent, and type of perpetrator (stranger, acquaintance, or relationship partner).
Approximately three-quarters of all respondents (ranging from 63.1 to 72.5% for men, and from 65.1 to 83.1% for women) reported being a victim of some form of violence, with the violent act most commonly perpetrated by a partner within a relationship (59.0% on male victims and 66.7% on female victims). Among women, Jamaica reported the highest level of any form of violence; among males, Barbados reported the lowest levels of any kind of violence. There was no statistically significant difference by gender (p = 0.43) or by country (p = 0.94) in the prevalence of physical violence.
The levels of any violence decreased as the victim's ages increasedfalling from 72.4% among the 1518 year olds to 67.3% among the 2730 year olds (p = 0.03). Reported physical violence fell from 66.2% among the 1518 year olds to 49.0% among the 2730 year olds (p < 0.001). Reported sexual coercion fell from 60.3% among the 1518 year olds to 50.1% among the 2730 year olds (p < 0.001).
Women were more likely to be a victim of sexual coercion (OR, 1.60; 95% CI, 1.351.90; p < 0.001). Compared to Barbados, Trinidad and Tobago had similar levels of sexual coercion (p = 0.07), whereas Jamaica had significantly higher levels of sexual coercion (OR, 2.19; 95% CI, 1.702.84; p < 0.001). After adjusting for age differences, more women were victims of any violence (OR, 1.23; 95% CI, 1.041.44; p = 0.01). Compared to Barbados, Trinidad and Tobago had similar levels of overall violence, whereas Jamaica, due to increased levels of coercion, had higher levels (OR, 1.68; 95% CI, 1.302.17; p < 0.001).
When incidence of IPV is further disaggregated to show victimization by strangers and acquaintances (Table 5) versus victimization by relationship partners (Table 6), some differences appear. Among strangers and acquaintances, physical violence increased with age (p < 0.001) and was higher in Jamaica than in Barbados (p < 0.001); for Trinidad and Tobago, there was no significant difference (p = 0.40). Women reported less physical violence against them than did the men (OR, 0.66; 95% CI, 0.550.78; p < 0.001). There was a significant gender difference only for the physical violence perpetrated by strangers. Sexual coercion increased with age (p = 0.01) until the mid-20s age group, but appeared to fall off thereafter. Sexual coercion was more than 2 times higher in Jamaica than in either Barbados or Trinidad and Tobago (p < 0.001). Women were 4 times more likely to be victims of sexual coercion than men (OR, 4.01; 95% CI, 2.695.98; p < 0.001).
IPV and psychological aggression among partners only
Table 6 shows the prevalence of reported physical and sexual IPV, and psychological aggression, within relationships (victimization as well as perpetration), stratified by country and sex of the respondent.
Victimization. Levels of psychological aggression were high. Over two-thirds of all survey respondents reported a history of psychologically aggressive behavior in a past or current relationship (more than 70% in both men and women in Barbados), with no statistically significant differences according to gender (p = 0.97), between the three participating countries (p = 0.07), or across different age groups (p = 0.16).
Levels of physical violence experienced among partners fell with age. When compared to the 1518 year age group, ORs show that persons aged 1922 years were 0.68 times less likely to be victims of violence (95% CI, 0.570.82; p < 0.001); those aged 2326 years were 0.46 times less likely (95% CI, 0.370.57; p < 0.001), and those aged 2730 years were 0.41 less likely (95% CI, 0.310.53; p < 0.001) (Figure 1). However, there were no differences between the genders in the prevalence of physical violence or between the three participating countries. Figure 1 presents physical violence and sexual coercion on survey respondents, whereas Figure 2 presents physical violence and sexual coercion by survey respondents. The age-related decline is similar in both graphs.
Sexual coercion was the only victimization experience that varied by country and by gender. Overall, the prevalence of sexual coercion reported by men was lower than that reported by women (OR, 0.69; 95% CI, 0.580.82; p < 0.001). As with physical violence, this prevalence also fell with agebeing highest among persons 1922 years and lowest among persons 27 years and over (Figure 1). Compared to Barbados, there was a higher prevalence of sexual coercion in Jamaica (OR, 2.18; 95% CI, 1.672.85; p < 0.001) and in Trinidad and Tobago (OR, 1.27; 95% CI, 1.021.58; p = 0.03).
Perpetration. Similar to the survey reports of high levels of psychological aggression as victims, the levels of psychological aggression were high for perpetrators, with no strong statistically significant differences by gender, country, or age group.
Fewer men than women reported being perpetrators of physical violence (OR, 0.76; 95% CI, 0.650.88; p < 0.001), and prevalence fell sharply with age compared to the 1821 age group (p < 0.001) (Figure 2). There were no significant differences in the prevalence of physical violence between the three participating countries.
In general, among the perpetrators, the type of violence that varied the most across countries and between genders was sexual coercion. Compared to Barbados, there was a higher prevalence of sexual coercion in Jamaica (OR, 2.20; 95% CI, 1.702.86; p < 0.001) and Trinidad and Tobago (OR, 1.31; 95% CI, 1.051.64; p = 0.02). Jamaica reported the highest levels of sexual coercion, but in all three countries, women consistently reported significantly higher levels of sexual coercion than men, both as perpetrators and as victims. The risk of sexual coercion also fell with age (p < 0.001).
Severe forms of physical violence among partners
The data were further broken down to examine gender, age, and country variations among those who were exposed to or perpetrated the more serious forms of physical violence within partnerships. The more serious forms of violence were defined as those that resulted in physical harm, and/or the use of a weapon, and/or that necessitated a visit to a health facility. The analysis is presented in Table 7. It may be noted that the drop-off in IPV by age was more dramatic in this subgroup of violent events, and Jamaica seemed to report fewer violent events than either Barbados or Trinidad and Tobago. In addition, and of particular importance, there was no significant difference between men and women in the number of reported violent events either on or by survey respondents.
The data reported in this article indicate a greater vulnerability of Caribbean men (versus women) to physical violence by strangers, andwith the possible exception of Trinidad and Tobagoa greater vulnerability of Caribbean women (versus men) to sexual coercion. However, when all types of violence from strangers and acquaintances, and within intimate partnerships, are examined, it is difficult not to be struck by the magnitude of the problem for both men and women in all of the countries studied. Among male victims, the figures reported for exposure to physical violence alone ranged from 54 to 61%; inclusion of other types of violence increases this figure to 6373%. Among females, the respective proportions are 5358% and 6583%, respectively. These figures fall inand even surpassthe upper end of the 1069% range reported in surveys worldwide (1, 17, 48).
The level of violence is greatest in Jamaica. However, the limited variations across the three countriesdespite their economic and social differencesare noteworthy, as well as the fact that when differences do occur, they do not necessarily fall in the expected direction. Jamaica, for example, reported higher levels of physical violence outside of relationships, compared to both Barbados and Trinidad and Tobago, but there were no significant between-country differences for physical violence within relationships; all fell within an incidence range of 4054%with Jamaica at the lower end. Even when the more severe forms of violence between partners are considered, Jamaicawith the lowest economic development indices, and the highest levels of violence overallseemed to report fewer events than either Barbados or Trinidad and Tobago.
According to this study, the arena for most violence and injury is indeed the partner or intimate relationship setting; this is similar to the findings from other studies (1). However, it is useful to note the large discrepancy between exposure to IPV within the context of a partnership, and that involving strangers or acquaintances. The proportion reporting physical assault by a stranger or acquaintance does not exceed 20%, whereas the proportion reporting assault by an intimate partner is never less than 40%. This, together with the finding that while IPV increases with age for strangers and acquaintances, it decreases with age for partners, could suggest that there may be limited overlap between the two types of experiences and perpetrators.
Social ecologists have asserted the existence of a " spatial concentration of violence," and violent and resource-deprived communities are generally expected to encourage domestic partner violence (1, 28, 49, 50). The results presented here, however, raise an important question: Given the apparently widespread occurrence of IPV and aggression, how useful are explanations and identification of risk factors based on the view that violence and aggression is something perpetrated by a minority of criminals, sociopaths, deviants, and delinquents?3 An important hypothesis of problem-behavior theory is that myriad behavioral problems stem from an underlying deviance syndrome, that is, they are interconnected manifestations of an underlying disposition toward deviance (51). The data from this study, however, along with that from the study by Bogart et al. (52), seem to contradict this hypothesis. Although some concur with the idea of the existence of a single risk factor in emerging adulthood that has a basis in adolescent risk, the evidence does not support this generalized risk factor as the cause of the variance in the individual risk indicators.
There is some evidence that living in a violent neighborhood does not necessarily produce violent children, and not everyone who is identified as " at risk" becomes involved in violence (53). The study reported on in this article, for example, suggests that co-occurrence of different types of violence or " clustering" is limited, and one type of violence is not necessarily a predictor of another. This supports Saunders' 1992 finding that those considered generally violent are only responsible for 20% of domestic violence (55). It may thus be deduced that only a limited relationship (if any) exists between the causes of violence within partnerships and the causes of violence outside partnerships. Evidence that the causes are different would have implications for decision-making regarding optimal intervention strategies for different types of violent behaviors. In any case, the limited co-occurrence of the different types of violence analyzed in this study was an unexpected finding and is therefore a potential area for further investigation. It also suggests a need for better differentiation of the various pathways to sociopathic versus socioculturally tolerated behaviors.
In fact, speculation on whether or not there are spatial concentrations of sociopaths and delinquents or if such concentrations would be more likely to occur among the poor and resource-deprived may be irrelevant. As suggested in a qualitative study of IPV and aggression conducted in Barbados (21), and by the author of this study (see footnote 7), it may be more helpful to recognize the existence of a universal culture of adversarial relationships, in a global environment permissive of the expression of violent solutions. The data from this study provide quantitative support for that possibility, and for some of the other conclusions that emerged from the qualitative study in Barbados. Among male respondents, when conflicts arose, a " win" versus negotiation and compromise tended to be the sought-after outcome; domestic quarrels were a " challenge" by the partner to be overcome, and a " war" to be won. Among both male and female respondents, emotional and psychological abusewith its potentially long-lasting impactswas feared to a considerably greater extent than was physical violence, with the latter considered more bearable because it had a clear beginning and end (21). In contexts in which violent and aggressive behaviors may be seen as a fairly normal and even valued means of social intercourse and negotiation, it seems logical to question the usefulness of conceptual frame-works that attribute social pathologies and " deviant" behaviors to various social problems and/or dysfunctional scenarios such as social exclusion and poverty and/or single, female-headed households. As noted by Tilley and Brackley (56), for many cases in which violence and aggression may be seen as " normal" and/or " deserved," the causal suspects or triggers are not the same.
Some have theorized that the root causes of violence lie in the legacy of slavery (1920). Given the high reported levels of violence found in societies without this kind of history (1), however, alternative explanations may need to be identified. In any event, it seems necessary to accurately identify the current factors that " justify" violent solutions. More attention needs to be given to identification of the dynamics, mores, and values in the wider cultural and social systems that may condone and even encourage violent behaviors.
Finklehor et al. asserted that " most studies on individual types of victimization have failed to obtain complete victimization profiles" (57: 8). The same could be said about studies of the perpetrators. This deficiency has allowed for over-exaggeration, understatement, and a complete lack of understanding of the impacts of particular types of victimization. For example, in societies where violence may be highly tolerated, the impactssingly or cumulativelymay be quite different than in those less tolerant of violence. It thus becomes critical to pose the following questions: In environments that tolerate high levels of violence, what is it that protects some individuals from suffering from or perpetrating IPV and aggression in intimate as well as non-intimate violent situations?
The other finding that is of particular significance is the general absence of significant gender differentials in exposure to and perpetration of physical violence among partners. The quantitative data and analysis from this study support suggestions from earlier studies (21, 44) about the possible significance of male battery in the three countries as well as conclusions from those studies that recognize the narrowness or narrowing of the " gender gap" (58, 59). The results of this study also support conclusions from qualitative studies conducted in the Caribbean, which also indicate the existence of male battery (22, 60). In addition, this study's quantitative data on female-initiated violence support the view that a culture of adversarial intimate relationships may be well entrenched (21).
Although Strauss and Gelles (6162) recognized the reality of male battery some time ago, there appears to have been some reluctance (perhaps as a consequence of ideological and cultural blinkers) to discuss or analyze this apparent syndrome (58, 32). In fact, male battery may not be a recent phenomenon: there is evidence that throughout history men have suffered violence at the hands of their wives and partners (6365). However, very little is known about whether the risk factors for male battery are any different from those for female battery; as Kernsmith (66) has observed, few studies have examined the " why" and " how" of female-perpetrated violence. Some studies now seek to determine if the higher incidence of female violence currently being reported is either retaliatory in nature, or the result of more accurate measurements and/or reporting, or if it is, in fact, the result of women acting as aggressors/initiators or perpetrators (6770). This is an area that requires a great deal more information, exploration, and analysis.
In the current study, the level of reported sexual coercion of men by females is high, unexpected, and perhaps even counter-intuitive. In addition, in two of the three countries (Barbados and Jamaica), the proportion of females reporting themselves as a perpetrator of sexual coercion was higher than that of males reporting themselves as a victim (ranging from 4768% and from 4057%, respectively). This discrepancy may be due to men's unwillingness to report battery and coercion by females, resulting in an understatement of male victimization levels, or to females over-exaggerating their actual activities.
With or without an exact correlation to the levels reported by self-described female perpetrators, the levels of sexual coercion by women being reported by males are high (53 and 57% in Trinidad and Tobago and Jamaica, respectively). This could be related to male perceptions of being under threat or siege found in a qualitative study of males in at least one Caribbean country (21). In most Caribbean societiesincluding the three examined in this studyavailable aggregate national data (13, 4547) show that females significantly outperform males at all levels of the educational system, and that while females may still be disadvantaged in terms of economic status and employment levels, they now experience greater social and economical mobility than males. As males increasingly fall further behind women and/or feel threatened or unable to perform their expected roles, reports of IPV perpetrated against them by women could stem from their perceptions and fears rather than actual reality. In either case, the figures for this type of IPV are remarkably large and therefore likely describe a significant reality requiring more in-depth analysis.
The data presented do not support that of other studies that suggest male/ female rates of self-reporting the perpetration of physical IPV is only similar for low levels of physical violence (6, 30). Reports from survey respondents show that in terms of perpetration between partners, there was no gender differential at higher levels of violence. Gender reporting may be skewed by the fact that females are likely to suffer greater injury than men in any confrontation (30); however, the capacity to inflict injury or violence should probably not be confused with the intent to be aggressively violent. This is an issue that requires further exploration. In any case, the likelihood that the " gender gap" may now be almost nonexistent reinforces the view that structural and psychosocial supports need to be better identified. Developing effective interventions and solutions requires a comprehensive understanding of the IPV phenomenon. It is therefore critical to determine if explanations of and intervention strategies for IPV should be based on/customized according to the gender of the perpetrator.
This study has several limitations, including the possibility of gender reporting bias, a syndrome that calls for further research. Reports on domestic violence indicate the existence of this type of bias, in which women report a greater number of events (e.g., psychological aggression, assault and injury) as both perpetrators and victims. Nevertheless, it may be argued that while the possible significance of a reporting bias needs to be carefully examined and addressed, the proportion of physical violence reportedly perpetrated by women is so high that the associated prevalence rates and conclusions would not be significantly affected. Another study limitation stems from the possibility that some of the reported sexual battery of males could pertain to men-on-men activities. As this study did not ask about homosexual activities, it was not possible to separate violence between male partners from that occurring among heterosexual partners. Given the homophobic character of these societies, however, homosexuality and its related activities would most likely be very under-reported (71), making it difficult to address this limitation in future studies.
