A comparison of adolescent inpatients with and without a history of violence perpetration: impulsivity, PTSD, and violence risk

How childhood maltreatment and violence victimization contributes to subsequent violent behavior remains an understudied area. We examined 130 psychiatrically hospitalized adolescents and compared those with a history of perpetrating violence to those without a history of violence perpetration. Perpetrators of physical violence were significantly more likely to have been a victim and/or witness to family and community violence and also reported significantly higher levels of a broad range of psychopathology than nonperpetrators. Correlational analyses with the study group of violence perpetrators revealed that higher levels of impulsivity, dissociation, and PTSD were significantly associated with higher levels of violence. Furthermore, multiple regression analysis showed that symptoms of impulsivity and PTSD contributed significantly to the prediction of violence risk. Our findings demonstrate that violence exposure and childhood maltreatment are indeed common negative life events among adolescent inpatients, and that symptoms of PTSD may predispose traumatized youth toward impulsive violent behavior.     

Correlates of community violence exposure in hospitalized adolescents.

To examine psychological and behavioral correlates of community violence exposure in psychiatrically hospitalized adolescents, 89 inpatients were administered a battery of psychometrically well-established self-report instruments. Violence exposure was assessed using the Child's Exposure to Violence Checklist (CEVC). Half of the patients reported exposure to multiple incidents violence in their community (52%) and home (53%). Sixty-one percent were victims of physical assault, and 39% were victims of sexual assault. Patients who had witnessed community violence reported significantly more post-traumatic stress disorder (PTSD) symptoms, drug use, and violence potential than patients without a history of witnessing community violence. Patients exposed to community violence were also more likely to be the victim of childhood maltreatment, as well as a perpetrator of violence. In conclusion, traumatization via exposure to community violence may serve as one important determinant in the development of mixed internalizing and externalizing psychopathology in adolescent inpatients, thus necessitating accurate assessment and treatment planning.     

Perpetration of violence, violent victimization, and severe mental illness: balancing public health concerns

OBJECTIVE: This review examined U.S. empirical studies published since 1990 of the perpetration of violence and of violent victimization among persons with severe mental illness and their relative importance as public health concerns. METHODS: MEDLINE, PsycINFO, and Web of Science were searched for published empirical investigations of recent prevalence or incidence of perpetration or victimization among persons with severe mental illness. Studies of special populations were included if separate rates were reported for persons with and without severe mental illness. RESULTS: The search yielded 31 studies of violence perpetration and ten studies of violent victimization. Few examined perpetration and victimization in the same sample. Prevalence rates varied by sample type and time frame (recall period). Half of the studies of perpetration examined inpatients; of these, about half sampled only committed inpatients, whose rates of perpetration (17%-50%) were higher than those of other samples. Among outpatients, 2% to 13% had perpetrated violence in the past six months to three years, compared with 20% to 34% who had been violently victimized. Studies combining outpatients and inpatients reported that 12% to 22% had perpetrated violence in the past six to 18 months, compared with 35% who had been a victim in the past year. CONCLUSIONS: Perpetration of violence and violent victimization are more common among persons with severe mental illness than in the general population. Victimization is a greater public health concern than perpetration. Ironically, the discipline's focus on perpetration among inpatients may contribute to negative stereotypes.     

Victimization and perpetration of intimate partner violence and substance use disorders in a nationally representative sample

ABSTRACT: The aim of this study was to examine the relationship between perpetration and victimization of physical and sexual intimate partner violence (IPV) in the past year and substance use disorders (SUDs) in the past year, including alcohol, sedatives/tranquilizers, cocaine, cannabis, and nicotine stratified according to sex. Data were from the National Epidemiologic Survey on Alcohol and Related Conditions. A series of adjusted logistic regression models were conducted. Among men and women, all types of SUDs were associated with increased odds of IPV perpetration (odds ranging from 1.4 to 8.5 adjusting for sociodemographic variables). IPV victimization increased the odds of having all types of SUDs for male and female victims, with the exception of sedatives/tranquilizer abuse/dependence among women (odds ranging from 1.5 to 6.0 adjusting for sociodemographic variables). Substances that had the most robust relationship with perpetration and victimization of IPV included alcohol and cannabis, after adjusting for sociodemographic variables, mood disorders, anxiety disorders, personality disorders, and mutual violence.     

Past violence and substance use disorder and subsequent violence towards others: six year analysis of the Assaulted Staff Action Program (ASAP)

Recent research has begun to document evidence of associations between past violence toward others, untreated personal victimization, and substance use disorder and later acts of violence toward others. This appears true for many types of individuals, including psychiatric patients who have been victims of violence. This six-year retrospective study sought to evaluate these possible associations in assaultive psychiatric patients. Data were gathered in the context of the Assaulted Staff Action Program (ASAP), a crisis intervention program for staff victims of patient assault. Both histories of violence (violence toward others and/or personal victimization) and substance use disorder in assaultive psychiatric patients were individually and jointly examined and found to be associated with subsequent assaults by these patients. Increased levels of both past violence toward others, personal victimization, and substance use disorder were associated with the largest increased frequency of subsequent assault. The implications and possible links to emergency mental health services are discussed [International Journal of Emergency Mental Health, 2(4), 241-247].     

Characteristics of recent violence among entrants to acute mental health and substance abuse services

OBJECTIVE: The aim of this study was to describe the characteristics of recent interpersonal violence perpetrated and experienced by individuals recruited from acute crisis mental health and substance abuse treatment settings and to examine differences among incidents involving individuals with mental disorders only (MDO), substance use disorders only (SDO), and co-occurring mental and substance use disorders (COD). METHOD: Participants (N = 419) were interviewed about their involvement in specific acts of violence in the past 30 days. Participants were also asked about where each incident took place, who was involved, whether individuals were injured, and whether alcohol or drugs were used before the incident. We examined distributions of violence characteristics for the full sample and used logistic regression analyses to test differences among incidents involving participants with MDO, SDO, and COD. RESULTS: Approximately 41% (n = 171) of the sample was involved in at least one incident of violence as a perpetrator or a victim, generating a total of 379 incidents. Far more incidents of violence involved victimization (62%) than perpetration (38%). Most incidents were isolated and involved only perpetration or only victimization. However, a total of 98 (26%) incidents occurred with another incident and constituted 49 episodes of violence that included incidents of perpetration and victimization. Characteristics of perpetration and victimization incidents were similar, except that victimization incidents involved more serious types of violence. The majority of incidents took place outdoors and did not result in injuries. Participants used drugs or alcohol prior to over 40% of incidents. Most incidents of perpetration (70%) targeted someone known to the participant. Diagnostic group was the strongest predictor of type of injury, location of incident, and use of alcohol and drugs before the incident. Individuals with substance use disorders, either alone or co-occurring with mental disorders, were more likely to report that violent incidents took place outdoors. Individuals with mental disorders, either alone or co-occurring with substance use disorders, were less likely to report alcohol and drug use prior to involvement in violence. CONCLUSIONS: Violence is common among individuals entering acute crisis mental health and substance abuse treatment. We found that such persons are more likely to report being victims of violence than perpetrators of violence. In contrast to prior studies, we found that most incidents took place outdoors. Although individuals in different diagnostic groups were no more or less likely to perpetrate or experience violence, they perpetrated and experienced violence under different circumstances. Implications and directions for future research and practice are discussed.     

The relationship of gambling to intimate partner violence and child maltreatment in a nationally representative sample

It has been suggested that family violence is associated with gambling problems. However, to date, this relationship has not been thoroughly investigated using representative data. The purpose of the current study was to analyze the relationship between gambling problems and the perpetration and victimization of intimate partner violence (including dating and marital violence) and child maltreatment (including minor child assault and severe child abuse) using nationally representative data. Data were drawn from the US National Comorbidity Survey Replication (n = 3334; 18 years and older). Multiple logistic and multinomial logistic regression models were used to examine the relationships between gambling and the perpetration and victimization of dating violence, marital violence, and child maltreatment. The results indicated that problem gambling was associated with increased odds of the perpetration of dating violence (Adjusted Odds Ratios (AORs) ranged from 2.2 to 4.2), while pathological gambling was associated with increased odds of the perpetration of dating violence (AORs ranged from 5.7 to 11.9), severe marital violence (AOR = 20.4), and severe child abuse (AOR = 13.2). Additionally, dating violence, marital violence, and severe child abuse victimization were associated with increased odds of gambling problems. The results were attenuated when adjusted for lifetime mental disorders. These findings can be used as evidence-based research to inform healthy public gambling polices and inform prevention and intervention efforts.     

Brief report: Associations between adolescent girls' social–emotional intelligence and violence perpetration

This study examined associations between social–emotional intelligence (SEI) and two measures of violence perpetration (relational aggression and physical violence) in a cross-sectional sample of high-risk adolescent girls (N = 253). We evaluated three aspects of SEI: stress management, intrapersonal, and interpersonal skills. Results of a multiple linear regression model accounting for participants' age, race/ethnicity, and experiences of relational aggression victimization indicated that girls with better stress management skills were less likely to perpetrate relational aggression. A parallel model for perpetration of physical violence showed a similar pattern of results. Study findings suggest that SEI, and stress management skills in particular, may protect adolescent girls – including those who have been victims of violence – from perpetrating relational aggression and physical violence. Interventions that build adolescent girls' social and emotional skills may be an effective strategy for reducing their perpetration of violence.     

Gender-based violence and mental disorders in female college students

Purpose

To assess the association between gender-based violence and DSM-IV Axis I disorders in female college students.

Methods

A stratified random sample of 1,043 college women (average age 22.2?years) participated in the study. We collected sociodemographic, socioeconomic and academic information as well as information on the participants’ experience of gender-based violence victimization. The presence of mental disorders during the 12?months preceding the study was assessed by clinically trained interviewers applying the Structured Clinical Interview for DSM-IV Axis I disorders-Clinician Version (SCID-CV).

Results

15.2% of the participants reported lifetime gender-based violence victimization. Almost two-thirds of the victims had suffered some Axis I disorder during the past year, a significantly larger proportion than among non-victims (OR?=?3.72; 95% CI 2.61–5.30). Mood disorders and anxiety disorders were both significantly more common among victims than non-victims (OR?=?4.26; 95% CI 2.81–6.46 and OR?=?1.97; 95% CI 1.20–3.24, respectively). The most prevalent individual disorder among victims was major depressive disorder (26.41%). Among victims of purely psychological violence, the overall rate of Axis I disorder was similar to the rate among other victims (67 and 61%, respectively).

Conclusions

Among female university students, the experience of physical or psychological gender-based violence is associated with mental disorder. These findings suggest the need for treatment and prevention interventions designed specifically for this population.     

Associations among symptoms of depression and posttraumatic stress disorder and self-reported health in sexually assaulted women

Symptoms of depression and posttraumatic stress disorder (PTSD) were examined for their association with health status in a sample of sexual assault victims. Hypotheses were that symptoms of each disorder would account for unique variance in health status among individuals exposed to traumatic stressors. Fifty-seven sexually assaulted college women were assessed for prior victimization history, assault characteristics, and depressive and PTSD symptoms. When prior history of sexual victimization, assault severity, and physical reactions during the assault were controlled, hierarchical multiple regression models indicated that symptoms of PTSD and depression were significantly associated with global health perceptions and severity of self-reported health symptoms. Only PTSD symptoms were significantly associated with reproductive health symptoms. The results suggest that both symptoms of PTSD and depression account for the relationship between exposure and health impairment among sexual assault victims.     

Perceptions of teachers' support, safety, and absence from school because of fear among victims, bullies, and bully-victims

This study examines the distribution of the types of involvement in school violence (bullies, victims, bully-victims, and students not involved in violence) among the general population of Israeli school students. The prevalence of these different types of involvement was also examined according to gender, age or school level (junior high vs. high school), and ethnicity (Jewish vs. Arab). Further, the study examines the relationships between type of involvement in school violence and students' perceptions of teachers' support, safety, and absence from school because of fear. Data were obtained from a nationally representative, stratified sample of 13,262 students in grades 7-11 who responded to a self-report questionnaire on victimization by, and perpetration of, school violence and on perceptions of school climate. Data revealed that 3.6% of all students were victims of bullying (18.5% of those involved in violence). The proportion of bully-victims among male students was 6.4% (21.9% of all involved) compared with 1.1% (11.2% of all involved) among females. Bully-victims reported the lowest levels of teacher support and feelings of security and missed school because of fear significantly more often. The results point to the uniqueness of the bully-victim group. This group presents multiple challenges for school staff with these students needing special attention.     

Correlates of suicide risk in adolescent inpatients who report a history of childhood abuse

The study objective was to examine correlates of suicide risk in psychiatrically hospitalized adolescents with a reported history of childhood abuse. Predictors of suicide risk were examined in 74 subjects who reported a history of childhood abuse and 53 depressed subjects who did not report a history of childhood abuse. Subjects completed a battery of psychometrically well-established self-report instruments to assess childhood abuse, suicide risk, and internalizing and externalizing psychopathology. Correlational analyses showed that higher levels of depression, self-criticism, and hopelessness were significantly associated with suicide risk in both study groups and violence was significantly associated with suicide risk in the childhood abuse group. For the childhood abuse group, multiple regression analyses with seven predictor variables accounted for 54% of the variance in suicide risk; depression and alcohol problems made significant independent contributions, while violence and self-criticism were independent predictors at the trend level. For the depressed/nonabused group, multiple regression analyses with the seven predictor variables accounted for 60% of the variance in suicide risk; depression, hopelessness, and self-criticism were independent predictors. Our findings suggest that both internalizing (i.e., depression or self-criticism) and externalizing (i.e., violence or alcohol) factors predict suicide risk in adolescent inpatients who report childhood abuse. This profile appears different from the more internalizing pattern (i.e., depression, self-criticism, and hopelessness) observed for the depressed adolescent inpatients who reported no history of childhood abuse.     

Mental disorder and serious violence: the victims

BACKGROUND: Media representation of violence by people with mental disorder tends toward images of random, serious violence to strangers. Studies of general psychiatric patients do not support this representation, but include few cases of serious or homicidal violence. This study describes the relationship of mentally disordered offenders to victims of an attack that was serious enough to result in the offender's detention in a high-security hospital. Hypotheses tested were that perpetrators of stranger violence would be more likely than those targeting people they know to be male, nonwhite, and younger and have a violence history and less likely to have psychotic features. METHOD: A clinical register and record study of all patients with an index offense of interpersonal violence who were resident in English high-security hospitals Jan. 1, 1993, to June 30, 1993, was conducted. RESULTS: Among 887 men and 88 women, 33% had attacked strangers. After adjustment for the high proportion of men in this male-dominated population, men were still more likely than women to have attacked strangers. There was no independent association between stranger victimization and perpetrator's age, ethnic group, or violence history. Stranger victimization was, however, more likely to have been committed by those with personality disorder than those with psychosis. The most serious violence and homicide were more likely to be against intimates than strangers. CONCLUSION: Among patients selected for high risk to the public, high rates of stranger victimization would be expected. The rates appeared, however, only slightly higher than in other reported patient samples and lower than in an untreated sample. The safety of people close to such patients urgently needs improvement.     

Sexual abuse in children and adolescents with intellectual disability

The present authors conducted a study of the occurrence of victimization and the perpetration of sexual abuse among 43 in‐patients with intellectual disability aged between 9 and 21 years who were admitted to a child and adolescent psychiatric in‐patient department over a period of 5 years. A retrospective case‐note review was employed that explored the nature and severity of abuse in relation to the age, gender and level of disability. The prevalence of abuse or abusive behaviour, i.e. 14% of 300 admissions, did not change over time. In 13 out of the 43 cases, the issue of sexual abuse was identified after admission. Victimization alone occurred in 21 cases, perpetration alone in six cases, and both victimization and perpetration in 16 cases. Fifty per cent of the victims had been abused by a member of their close or extended family. Most cases (62%) were adolescents. There was only one instance of a victim being abused by a female. However, there were five girls who were perpetrators, all of whom had previously been victims. By contrast, 11 out of the 17 male perpetrators had been victims. Despite difficulties of disclosure, it was possible to establish that severely disabled patients had suffered sexual abuse. The present data support theories which (1) recognize gender differences in sexual abuse patterns and (2) have a developmental perspective, incorporating the influence of adolescence.     

Effects of adolescent trauma exposure on risky behavior in college women

Individuals with sexual assault or abuse histories are likely to engage in risky sexual and other self-destructive behaviors. Studies of these behaviors, however, have focused on target traumatic events without accounting for other events in the participant's history, recency of the events, and/or developmental level at time of occurrence. The present study addressed some of these confounds by creating groups with unique and non-overlapping trauma histories among adolescent participants whose first trauma occurred at age 12 or older. Sophomore women from six regional campuses were screened in a two-stage procedure, and 209 of 363 final interviewees were included in the present report. These were assigned to a no trauma group, or to one of five groups with a unique trauma history: a single traumatic loss, a single physical assault, a single sexual assault, ongoing sexual or physical abuse, or multiple single traumas. Risky sexual behavior, suicidal ideation, and elevated perpetration of violence were most prominent among those with ongoing abuse exposure, although a single exposure to interpersonal violence during adolescence was sufficient for some risky behaviors. Major depression (MDD) and posttraumatic stress disorder (PTSD) were associated with many of the behaviors, and may serve to heighten risk.     

Adolescent stalking and risk of violence

Stalking perpetration and the associated risk for violence among adolescents has generally been neglected. In the present study, 1236 youth completed surveys assessing empirically established stalking indicators, threats and aggression toward stalking victims, dating violence, and violent delinquency. Latent Profile Analysis identified 3 latent classes of boys: non-perpetrators (NP), hyper-intimate pursuit (HIP), and comprehensive stalking perpetrators (CSP) and, and 2 classes for girls: NP and HIP. Boys in the CSP class were the most violent youth on nearly all indices with boys in the HIP class demonstrating an intermediate level of violence compared to NP boys. Girls in the HIP class were more violent than NP girls on all indices. These findings suggest stalking in adolescence merits attention by violence prevention experts. In particular, juvenile stalking may signify youth at risk for multiple forms of violence perpetrated against multiple types of victims, not just the object of their infatuation.     

Childhood maltreatment and risk of intimate partner violence: A national study

ObjectivePrior research indicates that different types of childhood maltreatment frequently co-occur and confer risk for adulthood intimate partner violence (IPV). However, it is unknown whether the risk of IPV is due to specific type(s) of maltreatment or to their shared association or both. Although these competing explanations have different implications for intervention, they have never been evaluated empirically.MethodData were drawn from a nationally representative survey of 34,653 US adults, the 2004–2005 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Structural equation modeling was used to simultaneously examine the shared and specific effects of five types of childhood maltreatment (i.e., sexual abuse, physical and emotional abuse and neglect) on the risk of different IPV behaviors (i.e., perpetration, victimization and reciprocal violence). Analyses were stratified by sex and adjusted for sociodemographic characteristics (i.e., age, personal income, educational background and race/ethnicity).ResultsMost types of childhood maltreatment increased the risk of victimization, perpetration and reciprocal violence. Effects of maltreatment types on each IPV behavior were exerted mostly through a latent factor representing the shared effect across all different types of maltreatment in both sexes (CFI = 0.990, TLI = 0.990, RMSEA = 0.023), although sexual abuse had an additional effect on victimization.ConclusionsBecause childhood maltreatment types increase the risk of each intimate partner violence behavior mainly through a general maltreatment dimension, underlying biological and developmental-ecological mechanisms should be considered important targets of prevention for both victimization and perpetration of abuse in adult relationships.     

Two International Conferences

Sexual violence can cause acute and persistent negative psychological outcomes among children and adults in a community. Previous studies have frequently reported high prevalence of prior child and adolescent sexual abuse among adult victims of sexual violence. This raises uncertainty over the specific contribution of sexual victimization in adulthood to the adverse psychological outcomes. The present study draws on a large nationally representative sample of adults without history of childhood sexual abuse, and applies diagnostic criteria of DSM-IV, in order to investigate the risk factors and psychiatric comorbidities correlated with sexual victimization in adulthood. In a large representative sample of U.S. adults without history of childhood sexual abuse, 2.5% reported sexual victimization in adulthood. Female gender, living alone, economic disadvantage, and a history of childhood adversities and parental psychopathology were identified as risk factors. Adult sexual victimization increased the risk of developing a variety of psychiatric disorders, especially PTSD (HR = 3.43, 95% CI [2.67, 4.41]) and drug abuse (HR = 3.38, 95% CI [2.49, 4.58]). Conversely, pre-existing psychiatric psychopathology, particularly PTSD (HR = 3.99, 95% CI [2.68, 5.94]) and dysthymia (HR = 2.26, 95% CI [1.42, 3.59]), increased the likelihood of sexual victimization in adulthood. Childhood experience and adulthood sociodemographic characteristics are important in affecting the risk of being sexually victimized in adulthood. Psychiatric disorders can act as both risk factors and outcomes of adult sexual victimization.     

Characteristics of American Assaultive Psychiatric Patients: Review of Published Findings, 2000–2012

Previous reviews of the literature from 1976 to 2000 documented two categories of assaultive psychiatric patients: (1) male patients with schizophrenic illness and histories of violence toward others and substance use disorder and (2) male/female patients with personality disorders and histories of violence toward others, personal victimization, and substance use. The present study reviewed the published findings on American assaultive patients from 2000 to 2012. The present findings partially supported the earlier findings in that patients with schizophrenic illness continued to present the greatest risk for assault. However, personality disordered patients were not equal in assault risk to patients with affective disorders. Possible explanations for these findings and a detailed methodological review are presented.
