Identifying and preventing IPV: Are clinicians doing enough?

Violence against women remains a global dilemma in need of attention. Physical violence in particular, is the most prevalent type of violence across all genders, races, and nationalities.

The Centers for Disease Control and Prevention says more than 43 million women and 38 million men report experiencing psychological aggression by an intimate partner in their lifetime. Meanwhile, 11 million women and 5 million men report enduring sexual or physical violence and intimate partner violence (IPV), and/or stalking by an intimate partner during their lifetimes, according to the CDC.1

Women who have endured this kind of violence might present differently from men. Some studies, for example, show a more significant association between mutual violence, depression, and substance use among women than men.² Studies on the phenomenon of IPV victims/survivors becoming perpetrators of abuse are limited, but that this happens in some cases.

Having a psychiatric disorder is associated with a higher likelihood of being physically violent with a partner.^3,4 One recent study of 250 female psychiatric patients who were married and had no history of drug abuse found that almost 68% reported psychological abuse, 52% reported sexual abuse, 38% social abuse, 37% reported economic abuse, and 25% reported physical abuse.⁵

Given those statistics and trends, it is incumbent upon clinicians – including those in primary care, psychiatry, and emergency medicine – to learn to quickly identify IPV survivors, and to use available prognostic tools to monitor perpetrators and survivors.

COVID pandemic’s influence

Isolation tied to the COVID-19 pandemic has been linked to increased IPV. A study conducted by researchers at the University of California, Davis, suggested that extra stress experienced during the COVID-19 pandemic caused by income loss, and the inability to pay for housing and food exacerbated the prevalence of IPV early during the pandemic.⁶

That study, where researchers collected in surveys of nearly 400 adults in the beginning in April 2020 for 10 weeks, showed that more services and communication are needed so that frontline health care and food bank workers, for example, in addition to social workers, doctors, and therapists, can spot the signs and ask clients questions about potential IPV. They could then link survivors to pertinent assistance and resources.

Furthermore, multiple factors probably have played a pivotal role in increasing the prevalence of IPV during the COVID-19 pandemic. For instance, disruption to usual health and social services as well as diminished access to support systems, such as shelters, and charity helplines negatively affected the reporting of domestic violence.

Long before the pandemic, over the past decade, international and national bodies have played a crucial role in terms of improving the awareness and response to domestic violence.^7,8 In addition, several policies have been introduced in countries around the globe emphasizing the need to inquire routinely about domestic violence. Nevertheless, mental health services often fail to adequately address domestic violence in clinical encounters. A systematic review of domestic violence assessment screening performed in a variety of health care settings found that evidence was insufficient to conclude that routine inquiry improved morbidity and mortality among victims of IPV.⁹ So the question becomes: How can we get our patients to tell us about these experiences so we can intervene?
 

 

Gender differences in perpetuating IPV

Several studies have found that abuse can result in various mental illnesses, such as depression, PTSD, anxiety, and suicidal ideation. Again, men have a disproportionately higher rate of perpetrating IPV, compared with women. This theory has been a source of debate in the academic community for years, but recent research has confirmed that women do perpetuate violence against their partners to some extent.^10,11

Some members of the LGBTQ+ community also report experiencing violence from partners, so as clinicians, we also need to raise our awareness about the existence of violence among same-sex couples. In fact, a team of Italian researchers report more than 50% of gay men and almost 75% of lesbian women reported that they had been psychologically abused by a partner.¹² More research into this area is needed.
 

Our role as health care professionals

The U.S. Preventive Services Task Force advises that all clinic visits include regular IPV screening.¹³ But these screenings are all too rare. In fact, a meta-analysis of 19 trials of more than 1,600 participants showed only 9%-40% of doctors routinely test for IPV.¹⁴ That research clearly shows how important it is for all clinicians to execute IPV screening. However, numerous challenges toward screening exist, including personal discomfort, limited time during appointments, insufficient resources, and inadequate training.

One ongoing debate revolves around which clinician should screen for IPV. Should the psychiatrist carry out this role – or perhaps the primary care physician, nurse, or social worker? These issues become even more fraught when clinicians worry about offending the patient – especially if the clinician is a male.¹⁵

The bottom line is that physicians should inquire about intimate partner violence, because research indicates that women are more likely to reveal abuse when prompted. In addition, during physician appointments, they can use the physician-patient therapeutic connection to conduct a domestic violence evaluation, give resources to victims, and provide ongoing care. Patients who exhibit treatment resistance, persistent pain, depression, sleeplessness, and headaches should prompt psychiatrists to conduct additional investigations into the likelihood of intimate partner violence and domestic abuse.

W also should be attentive when counseling patients about domestic violence when suggesting life-changing events such as pregnancy, employment loss, separation, or divorce. Similar to the recommendations of the USPSTF that all women and men should be screened for IPV, it is suggested that physicians be conscious of facilitating a conversation and not being overtly judgmental while observing body cues. Using the statements such as “we have been hearing a lot of violence in our community lately” could be a segue to introduce the subject.

Asking the question of whether you are being hit rather than being abused has allowed more women to open up more about domestic violence. While physicians are aware that most victims might recant and often go back to their abusers, victims need to be counseled that the abuse might intensify and lead to death.

For women who perpetuate IPV and survivors of IPV, safety is the priority. Physicians should provide safety options and be the facilitators. Studies have shown that fewer victims get the referral to the supporting agencies when IPV is indicated, which puts their safety at risk. In women who commit IPV, clinicians should assess the role of the individual in an IPV disclosure. There are various treatment modalities, whether the violence is performed through self-defense, bidirectionally, or because of aggression.

With the advancement of technology, web-based training on how to ask for IPV, documentation, acknowledgment, and structured referral increase physicians’ confidence when faced with an IPV disclosure than none.¹⁶ Treatment modalities should include medication reconciliation and cognitive-behavioral therapy – focusing on emotion regulation.

Using instruments such as the danger assessment tool can help physicians intervene early, reducing the risk of domestic violence and IPV recurrence instead of using clinical assessment alone.¹⁷ Physicians should convey empathy, validate victims, and help, especially when abuse is reported.

Also, it is important to evaluate survivors’ safety. Counseling can help people rebuild their self-esteem. Structured referrals for psychiatric help and support services are needed to help survivors on the long road to recovery.

Training all physicians, regardless of specialty, is essential to improve prompt IPV identification and bring awareness to resources available to survivors when IPV is disclosed. Although we described an association between IPV victims becoming possible perpetrators of IPV, more long-term studies are required to show the various processes that influence IPV perpetration rates, especially by survivors.

We would also like international and national regulatory bodies to increase the awareness of IPV and adequately address IPV with special emphasis on how mental health services should assess, identify, and respond to services for people who are survivors and perpetrators of IPV.
