Characteristics and treatment interests among individuals with substance use disorders and a history of past six-month violence: findings from an emergency department study

Substance use disorders and violent behaviour in patients with severe mental disorders: A prospective, multicentre study

OBJECTIVE

The relationship between alcohol and substance use and the risk of violence exhibited by patients with mental disorders is under-researched. This prospective cohort study aims to compare patients with severe mental disorders and with different substance use behaviors in terms of sociodemographic and clinical characteristics, hostility, impulsivity and aggressive behaviors. Furthermore, this study aims to assess differences in violent behaviors during a 1-year monitoring follow-up.

METHODS

A total of 378 participants with severe mental disorders from Italian residential facilities and from four Departments of Mental Health (244 outpatients and 134 residential patients) were enrolled. Participants were categorized as Persons with Current Substance Use, Persons with Former Substance Use and Persons with Non-Substance Use. All these patients underwent a complex multidimensional assessment, including the lifetime and current substance use; a subsample of outpatients was also assessed with a laboratory substance assay including the testing for specific substances. We assessed the differences among these three groups in hostility, impulsivity and aggressive behaviors.

RESULTS

The results of the close 1-year monitoring show a significantly higher risk of violence for patients with severe mental disorders Persons with Current Substance Use compared to Persons with Former Substance Use and Persons with Non-Substance Use. Persons with Current Substance Use showed significantly higher scores for irritability, negativism and verbal assault compared to Persons with Non-Substance Use. Persons with Former Substance Use showed significantly higher scores for lifetime history of aggressive behaviors compared with patients with Persons with Non-Substance Use.

CONCLUSION

These findings suggest that patients with comorbid mental illness and substance use disorders should be referred for specific interventions to reduce aggressive behavior and ensure patient well-being and community safety.

Gender differences in unidirectional and bidirectional intimate partner violence in addictions

Background: Few studies have analyzed the specific characteristics related to uni/bidirectional intimate partner violence (IPV) in patients with addiction problems. Knowing the specific profiles of these patients would allow the development of effective tailored interventions.Objective: This study assessed gender differences in unidirectional and bidirectional IPV among patients undergoing drug addiction treatment.Method: We sampled 122 patients (91 male and 31 female) who sought treatment in an addiction treatment center, and collected cross-sectional self-reported data on violent behaviors (physical, sexual and psychological violence), sociodemographic factors, distorted thoughts about women and violence, impulsiveness, and anger.Results: Ninety-one percent of participants reported experience of IPV (any type and any direction). Sixty-three percent of participants reported bidirectional violence, which was more common among women (83.9%) than men (56.1%). Unidirectional (perpetration only) IPV was reported in 28.7% of participants, and it was more common among men (34.1%) than women (12.9%). No one reported unidirectional (victimization-only) IPV. When only physical and/or sexual violence was considered, bidirectional violence affected 32.0% of the sample; 23.8% were only victims, and 3.3% were only perpetrators (all of them men). Participants who reported bidirectional violence had higher scores for impulsiveness, anger, and distorted thoughts.Conclusions: Bidirectional IPV is commonly reported among patients seeking treatment for addiction, particularly among women, and should be considered in future research and clinical practice.

Exposure to Violence and Substance Use Treatment Outcomes Among Female Patients

BACKGROUND

Many female substance use patients have experienced violence in the past, with most estimates showing the majority of patients reporting violent experiences at some point. Prior experience with violence has been linked to increased severity of substance use, and this may contribute to more challenges in the path to recovery.

OBJECTIVES

Existing research has confounded the timing at which violence has occurred with the type of violence to which patients have been exposed. The current study was conducted to specify the extent to which the timing of exposure and the type of violence were associated with substance use after discharge from treatment.

METHODS

Data were collected from 3,439 female patients included in the Comprehensive Assessment and Treatment Outcome Research (CATOR) system.

RESULTS

With regard to the type of exposure, findings indicated female patients who were exposed to multiple forms of violence (i.e. physical and sexual) displayed the greatest severity of substance use upon treatment initiation, as well as the greatest likelihood for use following discharge from treatment. In terms of the timing, female patients who experienced violence at various time points (i.e. before and after 18 years of age) displayed the greatest severity of substance use, but patients who experienced violence after 18 years of age had the highest probability of substance use following discharge from treatment. Conclusions/Importance: Clinicians should collect information related to these important details as treatment protocols are developed, and as patients are connected to aftercare services to minimize post-treatment substance use.

Trauma Center Youth Violence Screening and Brief Interventions: A Multisite Pilot Feasibility Study

Every day, 16 American youths between the ages of 10 and 24 years are murdered; 84% of these fatalities involve a firearm. Nearly half of traumatic youth deaths result from violence-related injuries. In 2013, 580,250 youth suffered nonfatal, assault-related injuries, necessitating emergency department treatment. The aim of this multisite pilot study was to examine the process, feasibility, and challenges of violence brief interventions (VBIs). The participants were youth between 15 and 25 years of age, at 2 major Level 1 trauma centers (TCs; TC1, TC2) in the Southeastern United States. Eligible participants (N = 38; TC1: n = 20, TC2: n = 18) received at least 1 VBI during their hospital stay, which provided information about individual screening results and elicited patients' perspectives on violent and risky behaviors. More participants at TC2 than at TC1 completed 2 VBI sessions. Barriers to and support of implementation were identified at both sites, and factors for improving implementation were identified, including the need for staff support through clinical guidelines and coordinated prevention and outreach programs. Further research is needed to identify factors for successful implementation of VBIs in TCs.

Associations between PTSD and intimate partner and non-partner aggression among substance using veterans in specialty mental health

BACKGROUND

Risk factors of violence perpetration in veterans include substance use and posttraumatic stress disorder (PTSD); however, it is unknown whether these factors are associated with greater risk for partner or non-partner violence. This study investigated the associations between probable PTSD, heavy drinking, marijuana use, cocaine use, and partner and non-partner violence perpetration.

METHODS

Self-report questionnaires assessing past-year partner and non-partner aggression (CTS2) as well as past-month substance use (SAOM), probable PTSD (PCL-C), and probable depression (PHQ-9) were administered to 810 substance using veterans entering VA mental health treatment.

RESULTS

In bivariate analyses, probable PTSD in substance using veterans was associated with violence perpetration (partner physical, χ²=11.46, p=0.001, φ=0.12; non-partner physical, χ²=50.64, p<0.001, φ=0.25; partner injury, χ²=6.41, p=0.011, φ=0.09; non-partner injury, χ²=42.71, p<0.001, φ=0.23). In multiple logistic regression analyses that adjusted for sociodemographic characteristics, probable PTSD was independently associated with non-partner physical (odds ratio [OR], 2.82; 95% confidence interval [CI], 1.97-4.05) and injury aggression (OR, 3.96; CI, 2.56-6.13). Cocaine and heavy drinking were independently associated with non-partner physical and injury aggression and non-partner injury aggression respectively.

CONCLUSIONS

The results provide evidence that probable PTSD, heavy drinking, and cocaine use are associated with increased risk of non-partner violence perpetration in substance using veterans. These results underscore the importance of screening for PTSD symptoms and violence perpetration towards non-partners in substance using veterans presenting for treatment.

Association between sociodemographic characteristics and anxiety levels of violence-exposed patients admitted to emergency clinic

BACKGROUND

Here we aimed to investigate sociodemographic characteristics, psychiatric history, and association between sociodemographic characteristics and anxiety levels of violence-exposed patients admitted to emergency clinic.

METHODS

This study consists of 73 violence-exposed patients admitted to emergency clinic who were literate and agreed to participate in the study. A sociodemographic data form created by us to investigate alcohol-substance abuse, suicide attempt, previous history of trauma, self and family history of psychiatric disorders and Beck Anxiety Inventory was given to the patients.

RESULTS

Of the patients exposed to violence 63% (n=46) were female and 27% (n=27) were male. Of these patients, 68.5% (n=50) were married, 43.8% (n=25) were workers, 34.2% were housewives, 11% were unemployed, and 11% were civil servants. Of the violence-exposed patients, 56.2% (n=41) were primary school, 21.9% (n=16) were high school, and 21.9% (n=16) were university graduates. Smoking and alcohol use rates were 54.8% (n=40) and 17.8% (n=13), respectively. The most common trauma type was assault using physical force with a ratio of 78.1% (n=57). In addition, anxiety scores were high in 42.5% (n=31) and moderate in 9.6% (n=7) of the patients. Mentioned psychiatric disorder was present in 17.8% (n=13) of the patients and 19.2% (n=14) of the patients' relatives. The correlation between sociodemographic characteristics and anxiety scores revealed that married patients had higher anxiety scores (P<0.01) and patients assaulted by their parents had lower anxiety scores (P<0.00).

CONCLUSION

A total of 63% of the violence-exposed patients admitted to emergency room were females, 56.2% were primary school graduates, and 43.8% were factory workers; this result shows that low socioeconomical status and education level affect exposure to trauma especially in females. In addition, ~20% of the patients and patients' relatives had a psychiatric disorder and 53.4% of perpetrators were parents, spouses, and children; this result shows that psychiatric history and family relations are one of the issues that should be taken into account and treated.

The intersecting roles of violence, gender, and substance use in the emergency department: a research agenda

The relationship between gender, violence, and substance use in the emergency department (ED) is complex. This article examines the role of gender in the intersection of substance use and three types of violence: peer violence, intimate partner violence, and firearm violence. Current approaches to treatment of substance abuse and violence are similar across both genders; however, as patterns of violence and substance abuse differ by gender, interventions may be more effective if they are designed with a specific gender focus.
