Acute Exercise Improves Inhibitory Control but Not Error Detection in Male Violent Perpetrators: An ERPs Study With the Emotional Stop Signal Task

Violence has been linked to the co-occurrence of cognitive dysfunction and altered activations in several brain regions. Empirical evidence demonstrated the benefits of acute exercise on motor inhibition and error detection and their neuronal processing. However, whether such effects also hold for the population with violent behaviors remains unknown. This study examined the effects of acute aerobic exercise on inhibitory control and error monitoring among violent offenders. Fifteen male violent offenders were counterbalanced into experimental protocols, which comprised a 30-min moderately aerobic exercise [60% heart rate (HR) reserve] and a 30-min reading control session. After each session, participants performed an emotional stop signal task while event-related potentials (ERPs) were recorded simultaneously. Results showed insignificant changes in ERPs components [i.e., N2, P3, error-related negativity (ERN), and error-positivity (Pe) amplitudes] and the behavioral performance in go condition, stop accuracy, and post-error adjustments by exercise. However, the current study demonstrated that the acute exercise facilitated stop signal reaction time (SSRT) when compared to the control session regardless of emotional conditions. This is the first research to exhibit the improvements in inhibitory performance by acute exercise for violent offenders. Most importantly, this effect was independent of affective settings, expanding the existing knowledge of the influences of acute exercise on cognition. Our findings implicate the perspective of acute exercise for clinical and correctional practices.

Hazardous drinking and exposure to interpersonal and community violence on both sides of the U.S. -Mexico border

Objective

Different patterns of heavy drinking occur by country and proximity to the U.S. Mexico border. Few studies describe the impact of violence on drinking between countries and along the border.

Methods

Survey data is from U.S. Mexican origin adults living in Texas and Mexican border and non-border cities, N=4,796. Participants were asked about alcohol consumption, interpersonal physical violence (IPV) and exposure to community violence. Monthly hazardous drinking (5+/4+ for men/women) was the primary outcome. Multivariate logistic regression model comparisons identified best predictors.

Results

In the U.S. hazardous drinking was associated with past year IPV (OR_adj=2.5; 1.8-3.5) and community violence (OR_adj=1.4; 1.1-1.8). In Mexico, IPV (OR_adj=3.9; 2.0-7.4) and border proximity (OR_adj=0.5; 0.4-0.8) were associated with hazardous drinking but not community violence.

Conclusion

Hazardous drinking is associated with IPV in both countries, but violence did not explain border hazardous drinking differences where they existed in Mexico.

Factors Explaining Variation in Alcohol Use Disorder Prevalence Across Border and Nonborder Communities in Texas

BACKGROUND

U.S. border populations have been found to be at high risk for alcohol problems. However, results from the U.S.-Mexico Study on Alcohol and Related Conditions (UMSARC) revealed surprisingly large variation in alcohol outcomes even among Texas border sites, with alcohol use disorder (AUD) prevalence ~1.5 to 1.6 times greater in the border city of Laredo compared to both San Antonio and the border site of McAllen/Brownsville. Because a better understanding of this variation is important to identifying environmental influences on AUD, we developed and tested a conceptual model addressing variation in AUD prevalence across Texas UMSARC sites.

METHODS

Surveys involved in-person, household interviews with Mexican-origin residents of the Texas border cities Laredo (n = 751) and McAllen/Brownsville (n = 814), with San Antonio as an off-border comparison (n = 771). Interviews assessed past-year DSM-5 AUD; past-year heavy drinking; coping and enhancement motives; and 7 indicators of substance use climate and stress exposure hypothesized to mediate site effects. Analyses, conducted separately by gender, included regressions and structural equation modeling with Mplus.

RESULTS

Preliminary analyses revealed that site effects on AUD prevalence were, unexpectedly, exclusive to men, and that Laredan men were similar to McAllen/Brownsville men on demographics, acculturation, and cross-border mobility. However, sites differed dramatically on most of the hypothesized risk factors. Structural equation models confirmed that site effects on AUD were partially mediated via effects of site on indicators of a permissive climate (i.e., permissive drinking norms, high drug availability) and stress exposures (i.e., high exposure to violence/crime, low family support), and via downstream effects on drinking motives and heavy drinking.

CONCLUSIONS

Findings of very high rates of past-12-month AUD among Laredan men (35%) suggest the possibility of significant heterogeneity even within demographically similar border areas and underline the need for additional study of the border region. Findings regarding our conceptual model suggest that this model may constitute a useful initial framework for future research on alcohol problems at the border. However, additional research using representative samples is needed to confirm and expand this model to comprehensively address relevant individual and community factors.

Drinks per day in women of Mexican origin: does birth place matter?

Historically, Mexican-born women who immigrate to the United States (U.S.) have lower levels of alcohol use and higher rates of abstinence compared with Mexican American women born in the U.S. and other racial groups in the U.S. As such, immigrant women's alcohol use has received limited attention by the research community. Gaps in knowledge of their alcohol use patterns, changes in healthy drinking recommendation for women, and projections of population growth in both Mexican immigrant and Mexican American populations support the need for the study. Data from the Center for Disease Control's National Health Interview Survey were used to explore alcohol use differences in women of Mexican origin born in and outside of the U.S. In addition, the relationship between years in the U.S. and drinks per day was explored in Mexican immigrant women. The results indicated that Mexican immigrant women who drink are drinking above recommended levels and the younger immigrant women are drinking more drinks per day than young Mexican American women. These changes point to the importance of developing culturally sensitive interventions for this expanding segment of the population.

Rape, sex partnership, and substance use consequences in women veterans

The association of rape history and sexual partnership with alcohol and drug use consequences in women veterans is unknown. Midwestern women veterans (N = 1,004) completed a retrospective telephone interview assessing demographics, rape history, substance abuse and dependence, depression, and posttraumatic stress disorder (PTSD). One third met lifetime criteria for substance use disorder (SUD), half reported lifetime completed rape, a third childhood rape, one quarter in-military rape, 11% sex with women. Lifetime SUD was higher for women with rape history (64% vs. 44%). Women with women as sex partners had significantly higher rates of all measures of rape, and also lifetime substance use disorder. Postmilitary rape, sex partnership, and current depression were significantly associated with lifetime SUD in multivariate models (odds ratio = 2.3, 3.6, 2.1, respectively). Many women veterans have a high need for comprehensive mental health services.

Child physical and sexual abuse: a comprehensive look at alcohol consumption patterns, consequences, and dependence from the National Alcohol Survey

BACKGROUND

Previous research has documented a relationship between child sexual abuse and alcohol dependence. This paper extends that work by providing a comprehensive description of past year and lifetime alcohol consumption patterns, consequences, and dependence among women reporting either physical and sexual abuse in a national sample.

METHODS

This study used survey data from 3,680 women who participated in the 2005 U.S. National Alcohol Survey. Information on physical and sexual child abuse and its characteristics were assessed in relation to 8 past year and lifetime alcohol consumption measures.

RESULTS

Child physical or sexual abuse was significantly associated with past year and lifetime alcohol consumption measures. In multivariate analyses, controlling for age, marital status, employment status, education, ethnicity, and parental alcoholism or problem drinking, women reporting child sexual abuse vs. no abuse were more likely to report past year heavy episodic drinking (OR(adj) = 1.7; 95% CI 1.0 to 2.9), alcohol dependence (OR(adj) = 7.2; 95% CI 3.2 to 16.5), and alcohol consequences (OR(adj) = 3.6; 95% CI 1.8 to 7.3). Sexual abuse (vs. no abuse) was associated with a greater number of past year drinks (124 vs. 74 drinks, respectively, p = 0.002). Sexual child abuse was also associated with lifetime alcohol-related consequences (OR(adj) = 3.5; 95% CI 2.6 to 4.8) and dependence (OR(adj) = 3.7; 95% CI 2.6 to 5.3). Physical child abuse was associated with 4 of 8 alcohol measures in multivariate models. Both physical and sexual child abuse were associated with getting into fights, health, legal, work, and family alcohol-related consequences. Alcohol-related consequences and dependence were more common for women reporting sexual abuse compared to physical abuse, 2 or more physical abuse perpetrators, nonparental and nonfamily physical abuse perpetrators, and women reporting injury related to the abuse.

CONCLUSION

Both child physical and sexual abuse were associated with many alcohol outcomes in adult women, even when controlling for parental alcohol problems. The study results point to the need to screen for and treat underlying issues related to child abuse, particularly in an alcohol treatment setting.

Sexual victimization in female and male college students: examining the roles of alcohol use, alcohol expectancies, and sexual sensation seeking

Alcohol and alcohol expectancies relate to sexual victimization. The present study examined these links in a sample of 407 predominantly Hispanic male and female college students, along the Mexico-US border. The study also examined the independent contribution of sexual sensation seeking to the prediction of victimization. Results showed that victimization was associated with alcohol risk, alcohol consumption-related problems, and positive alcohol expectancies. Importantly, sexual sensation seeking independently predicted victimization and did so after controlling for alcohol risk and expectancies. Our results suggest that associations among victimization, alcohol risk, and expectancies generalize to Hispanic women and men. The study's limitations are noted.

Intimate partner violence among Latinas in eastern North Carolina

This article explores the correlates of intimate partner violence (IPV) among rural, southern Latinas. A sample of 1,212 women in blue-collar work sites in rural North Carolina completed a questionnaire assessing IPV and other social, demographic, and health-related variables. Social and demographic correlates of IPV were examined. Adult lifetime prevalence of IPV in Latinas was 19.5%, similar to that of non-Latinas. As compared to Latinas who did not experience IPV and non-Latinas who experienced IPV, Latinas who experienced IPV were more likely to lack social support and to have children in the home. Agencies that provide services to victims of IPV in the rural South need to be prepared to meet the unique needs of Latina immigrants.

From the margins to the center: ethnic minority women and the mental health effects of sexual assault

The trauma of sexual assault is heightened for many women by the interlocking experience of societal traumas such as racism, sexism, and poverty. The mental health effects of sexual assault are mediated by race and ethnicity. The investigators explore the experiences of African American, Asian American, Latina, and Native American female survivors of sexual assault. The sociohistorical context of intergenerational trauma in the lives of ethnic minorities is a part of the context for the contemporary experience of sexualized violence. Racial and ethnic dynamics related to sexual assault prevalence, mental health effects, and disclosure are examined. Literature related to cultural beliefs, community attitudes, and perceived social support in relation to sexualized violence are also reviewed. Finally, practice, research, and policy implications are discussed.

Intimate partner violence in Latina and non-Latina women

BACKGROUND

No single study has delineated the prevalence of intimate partner violence (IPV) over multiple time periods for Latina versus non-Latina women and compared the health of abused Latina women to the health of abused non-Latina women using multiple health indicators. The objective of this study was to describe the prevalence of IPV over multiple time periods and the association between lifetime IPV exposure and current health in Latina and non-Latina women.

METHODS

A total of 3429 women (mean age=47 years) were randomly sampled from a large U.S. healthcare system; 139 (4%) were Latina. During a telephone survey, past-5-year and past-year IPV prevalence was assessed using five questions on physical and psychological abuse from the Behavioral Risk Factor Surveillance System (BRFSS), and ten questions from the Women's Experience with Battering Scale; lifetime IPV prevalence was assessed using the BRFSS questions. Current physical, social, and mental health was assessed using well-validated questionnaires.

RESULTS

Prevalence of IPV for Latina versus non-Latina women was, respectively: 44.6% vs 44% lifetime; 20.1% vs 14.5% for the past 5 years; and 11.5% vs 7.8% for the past year. In models adjusted for age and income, women with a lifetime IPV history had significantly worse health compared to non-abused women across many health indicators; for example, Latina women with a lifetime IPV history had Short Form-36 Health Survey (SF-36) subscale scores that were 5.62 (mental health) to 7.77 (vitality) points lower than those for non-abused Latina women; depression prevalence more than two times higher; and more physical symptoms. Adverse IPV-related health was significantly worse for Latina than non-Latina women for overall mental health functioning (p<0.02), vitality (p<0.01), and emotional functioning (p<0.01) according to SF-36.

CONCLUSIONS

This exploratory study showed that IPV is common in Latina and non-Latina women, and adverse IPV-related mental health was pronounced in Latina women.

Health status of Mexican-origin persons: do proxy measures of acculturation advance our understanding of health disparities?

OBJECTIVES

This paper compares select health status indicators between the U.S. and Mexico, and within the Mexican-origin population using proxy measures of acculturation.

METHODS

Statistical data were abstracted and a Medline literature review conducted of English-language epidemiologic articles on Mexican-origin groups published during 1976-2005.

RESULTS

U.S.-born Mexican-Americans have higher morbidity and mortality compared to Mexico-born immigrants. Mexico has lower healthcare resources, life expectancy, and circulatory system and cancer mortality rates, but similar infant immunization rates compared to the U.S. Along the U.S.-Mexico border, the population on the U.S. side has better health status than the Mexican side. The longer in the U.S., the more likely Mexican-born immigrants engage in behaviors that are not health promoting. Conclusions Researchers should consider SEP, community norms, behavioral risk and protective factors when studying Mexican-origin groups. It is not spending-time in the U.S. that worsens health outcomes but rather changes in health promoting behaviors.

Is sexual victimization gender specific?: the prevalence of forced sexual activity among men and women in denmark, and self-reported well-being among survivors

The present study investigates the prevalence of sexual victimization and correlations between sexual victimization and indicators of poor health in two representative samples of men and women in Denmark. Specifically, the authors explore the prevalence of self-reported victimization among adolescents (N = 5,829) and adults (N = 3,932) and analyze differences in self-reported health outcomes between male and female victims and corresponding controls. Gender differences are found in the reported prevalence of sexual victimization. Significantly more females than males reported forced sexual experiences in both samples. Associations between sexual victimization and poor health outcomes are found for both genders. Comparable patterns of association for men and women are found on a number of variables, particularly those pertaining to risk behavior.

Substance abuse prevalence and treatment among Latinos and Latinas

Substance abuse prevalence rates for Latinos/as generally mirror those of the general U.S. population; however, a number of indicators of assimilation to U.S. culture as well as sociodemographic variables predict substance use and abuse among this group. Latinos/as have poorer outcomes in substance abuse treatment programs. Yet there is little empirical evidence that explains the problems these individuals experience in treatment, and there are few studies on the use and effectiveness of mutual help groups among this population. New developments in the conceptualization and measurement of acculturation will lead to a greater understanding of the role of culture in the prevalence and treatment of substance-related problems.

Reasons for intimate partner violence perpetration among arrested women

There are limited empirical data regarding the reasons or motives for the perpetration of intimate partner violence among women arrested for domestic violence and court referred to violence intervention programs. The present study examined arrested women's self-report reasons for partner violence perpetration and investigated whether women who were victims of severe intimate partner violence were more likely than were women who were victims of minor partner violence to report self-defense as a reason for their behavior. In all, 87 women in violence intervention programs completed a measure of violence perpetration and victimization and a questionnaire assessing 29 reasons for violence perpetration. Self-defense, poor emotion regulation, provocation by the partner, and retaliation for past abuse were the most common reasons for violence perpetration. Victims of severe partner violence were significantly more likely than were victims of minor partner violence to report self-defense as a reason for their violence perpetration. The clinical implications of these findings are discussed.

Psychopathology in women arrested for domestic violence

This study examined the prevalence of psychopathology among women arrested for violence and whether the experience of intimate partner violence (IPV) was associated with Axis I psychopathology. Women who were arrested for domestic violence perpetration and court referred to violence intervention programs (N= 103) completed measures of IPV victimization, perpetration, and psychopathology. Results revealed high rates of posttraumatic stress disorder (PTSD), depression, generalized anxiety disorder (GAD), panic disorder, substance use disorders, borderline personality disorder, and antisocial personality disorder. Violence victimization was significantly associated with symptoms of psychopathology. Logistic regression analyses showed that sexual and psychological abuse by partners were associated with the presence of PTSD, depression, and GAD diagnoses. Results highlight the potential importance of the role of violence victimization in psychopathology. Results suggest that Axis I and Axis II psychopathology should routinely be assessed as part of violence intervention programs for women and that intervention programs could be improved by offering adjunct or integrated mental health treatment.

Trauma history and relapse probability among patients seeking substance abuse treatment

We estimated the prevalence of trauma history and relapse in a sample of 959 patients at two outpatient chemical dependence clinics of a managed healthcare organization. A large majority (89%) reported a history of at least one traumatic event. The most common traumatic events were serious accidents, being robbed, seeing someone killed or seriously injured, and partner violence. One third of the patients had a history of substance abuse disorder relapse. There were gender and ethnic differences in the types of traumatic events reported. There were ethnic differences in relapse rates, which were highest among African American and multicultural patients. The types of traumatic events reported differed in patients of various sexual orientations. Bisexual patients had the highest rates of relapse, even when trauma exposure was controlled. Clinical implications of the findings are discussed.

Socioeconomic, cultural, and personal influences on health outcomes in low income Mexican-origin individuals in Texas

Several studies have suggested that the health of Mexican-Americans is better than expected given their low socioeconomic status. The healthy migrant hypothesis and the acculturation hypothesis, stating that the foreign-born and the less acculturated enjoy better health, have been proposed as possible complementary explanations. However, it is not clear which are the socioeconomic, cultural, and personal characteristics that favor good health and that differentiate foreign-born from US-born and unacculturated from acculturated Mexicans. In this paper, we compare, by nativity and acculturation level, the socioeconomic, cultural, and personal characteristics in a sample of low income mostly female Mexican-origin individuals living in Texas and investigate their contribution to differences in self-reported physical health, mental health, and self-rated health (SRH) status. Using a multistage probability sample, we completed 1745 interviews with Mexican-origin individuals. The survey instrument included the SF-12, demographic and socioeconomic information, and questions on social support, religiosity, fear of victimization, trust, perceived racism, and perceived opportunity. Nativity and use of the Spanish language were combined into a nativity/acculturation variable. We estimated multivariate regressions and ordered logit regressions to investigate the association of health outcomes to nativity/acculturation and socioeconomic, cultural, and personal characteristics. Overall, the distribution of strengths (more social support, trust, perceived personal opportunities and less perceived victimization) reflected a nativity-based income gradient and an education gradient reflecting language use. Health outcomes varied by nativity/acculturation after controlling for socioeconomic, cultural, and personal characteristics. Physical health differed by nativity, supporting the healthy migrant hypothesis, while nativity-based differences in mental health were explained by socioeconomic and personal characteristics. SRH varied by language use, suggesting a culturally conditioned response. The socioeconomic, cultural, and personal factors affected health outcomes differently. These findings suggest a complicated interaction between nativity, acculturation, and economic factors in determining social and personal strengths and their influences on health.

Prevalence and co-occurrence of violence, substance use and disorder, and HIV risk behavior: a comparison of sheltered and low-income housed women in Los Angeles County

BACKGROUND

Violence against women, substance use and disorder, and HIV represent three significant threats to the health of women, yet little is known about the extent of these epidemics among indigent women. This study investigates and documents differences in the prevalence and co-occurrence of physical and sexual violence, substance use and disorder, and HIV risk behavior in sizable probability samples of sheltered homeless and low-income housed women.

METHODS

Retrospective self-reports were obtained through structured interviews with stratified random samples of women residing in shelters (N = 460) and low-income housing (N = 438) in Los Angeles County, California.

RESULTS

Sheltered women were more likely than housed women to report experiencing physical and sexual violence, substance use and disorder, HIV risk behavior, and co-occurrence of these problems in the past year. Differences remained when propensity weights were used to equate the groups on demographic and background characteristics.

CONCLUSIONS

Findings suggest remarkable need for services among communities of indigent women. Higher rates of problems among women in shelters highlight the importance of differentiating among subgroups of indigent women in community-based prevention and intervention activities and tentatively suggest a protective influence of housing.

Treatment for alcohol-related problems: special populations: research opportunities

For the subgroups indicated, a few questions/issues are relevant to all three (women, elderly, minorities): 1. Heterogeneity of the special populations, for example, Hispanic-Americans are from different countries with different cultures. Women and the elderly vary by age, education, income, social class, health status, etc., to say nothing of ethnicity/color/religion. 2. Of therapy modalities, professional and indigenous, which are more efficacious? 3. Are group-specific therapies needed, or will sensitivity to a particular group work as well? WOMEN: Stereotypes and myths have prevailed, for example, the long-standing belief that women have poorer prognoses than male alcoholics. When female and male alcoholics are compared, women report more positive family history, a later onset of drinking and problems, more marital disruption, more comorbidity, etc. The review of treatment outcomes (Vannicelli, 1986) showed few significant gender differences in outcomes. Research recommendations include biological and genetic studies, women's view of and use of therapeutic modalities, and outcome studies of different modalities, including all female facilities. ELDERLY: Medications are used more by older patients, and such patients are more likely to experience adverse drug reactions. In the moderate social use of alcohol, there are conflicting reports and the extent of elderly use awaits decisive study. The etiology of problem drinking by older persons is studied rarely. An attempt has been made to explain onset later in life (vs. earlier onset) based on the stresses of aging (loss, loneliness, health problems, etc.); research results have not been supportive. Consequences of older persons' heavy drinking seems to be most often alcohol-related medical disorders, although there are often familial and social consequences. Atkinson (1995) recommended the development of elder-specific outcome measures, study of the efficacy of different treatment modalities, and study of the efficacy of treatment for patients in elder-specific and mixed age groups, etc. MINORITIES: Each of the federally mandated minority groups in the United States is heterogeneous. The epidemiology of use and abuse of alcohol and other drugs is well studied, but treatment issues are not. AMERICAN INDIANS: There are more than 200 tribes; each has its own customs and culture. Some tribes are abstinent; others have big problems with abuse of alcohol, and other drugs. Orthodox treatment methods, used by professional counselors and therapists, have not worked very well.

RECOMMENDATION

study of traditional Indian forms of healing practices combined with other treatment; this would be a culture-sensitive model. BLACK AMERICANS: This includes not only African-Americans but people from the Caribbean, Central and South America, etc. Among African-Americans, there is a history of ambivalence toward alcohol: on the one hand, a tolerant "nightclub culture" and on the other, church beliefs in temperance and abstinence. There is "respectable drinking" and "problem drinking," most often defined as solitary or public drinking. The primary source of support is considered familial, so people tend to be distrustful of therapy from "strangers." They are anonymous in promoting sobriety and study of subcultural norms and the history of slavery. Earlier ethnographic works (Liebow, 1967) were of "street-corner men," slum dwellers, ghetto norms; recommended: studies of middle-class African-American life and drinking behaviors. ASIAN-AMERICANS: A study in Los Angeles reports differences among Chinese, Japanese, Filipinos, and Koreans in drinking beliefs and behavior. Of these groups, the Japanese in Japan and the Japanese-Americans report the largest number of heavy drinkers. It is, however, considered a private matter, even when associated with social problems. Interestingly, there is an organization called the All Nippon Sobriety Association (like Alcoholics Anonymous). RECOMMENDATIONs: studies of generational differences among Japanese-Americans in use and efficacy of treatment. For the Chinese-Americans, who are fairly permissive about older persons' drinking and share a belief in the health benefits of alcohol, a gender/gerontological study is recommended. HISPANIC-AMERICANS: As a total group, they drink more and present more alcohol-related problems than other immigrant minorities. Age, ethnicity, and gender patterns in permissiveness to drink need to be explored. Treatment sought is often in pentecostal churches and Centros for Espiritismo. Hispanics are not likely to seek help in formal clinical settings which emphasize alcohol consumption as the basic, core problem. They are more likely to seek out and be responsive to the perception of their drinking problem as sin and a rejection of Jesus. It is not that minorities do not recognize problems and seek out help. They are not likely to seek out the health profession's offering of outpatient clinics, residential treatments, etc.
