Psychiatr Ment Health Nurs. Author manuscript; available in PMC 2014 Mar 1. Published in final edited form as: PMCID: PMC3411865 NIHMSID: NIHMS357923 Aggressive behavior is the observable manifestation of aggression and is often associated with developmental transitions and a range of medical and
psychiatric diagnoses across the lifespan. As healthcare professionals involved in the medical and psychosocial care of patients from birth through death, nurses frequently encounter—and may serve as—both victims and perpetrators of aggressive behavior in the workplace. While the nursing literature has continually reported research on prevention and treatment approaches, less emphasis has been given to understanding the etiology, including contextual precipitants of aggressive behavior. This
paper provides a brief review of the biological, social, and environmental risk factors that purportedly give rise to aggressive behavior. Further, many researchers have focused specifically on aggressive behavior in adolescence and adulthood. Less attention has been given to understanding the etiology of such behavior in young children and older adults. This paper emphasizes the unique risk factors for aggressive behavior across the developmental spectrum, including childhood, adolescence,
adulthood, and late life. Appreciation of the risk factors of aggressive behavior, and, in particular, how they relate to age-specific manifestations, can aid nurses in better design and implementation of prevention and treatment programs. Keywords: Aggression, Concept Analysis Aggressive behavior is an associated symptom of many psychiatric
disorders and can manifest throughout the life span, from attention-deficit hyperactivity disorder (ADHD) in children and adolescents, to domestic violence in adults, to dementia in older adults. While much of the aggression literature has focused on adolescents and adults, less attention has been given to understanding the etiology of aggressive behaviors across the entire developmental spectrum. The purpose of this paper is to provide an overview of the manifestation and causes of aggressive
behavior across the life span as well as provide suggestions for the roles that nurses, who frequently interact with patients from all age groups, can play in preventing and intervening in aggressive behavior. Potential consequences to both the victims and aggressors are also outlined. Aggression is a highly studied area in the psychosocial literature, particularly adolescent aggression and developmental theories, adult aggression and violence, aggression and criminal behavior, and
psychopathology. These discussions have been detailed elsewhere (Card, Stucky, Sawalani, & Little, 2008; Kempes, Matthys, de Vries, & van Engeland, 2005;
Liu & Wuerker, 2005; Loeber & Hay, 1997; Stoff & Cairns, 1996). This paper is intended to provide a basic overview of aggressive behavior and its
presentation and risk factors in major age groups so as to facilitate nurses and nursing researchers in better understanding, identifying, preventing, and treating this phenomenon. In doing so, we provide a model for anticipating, responding to, and preventing aggressive behavior across the age spectrum. Although interrelated, it is important to differentiate between the concepts of aggression, aggressive behavior,
and violence (Liu, 2004a). Aggressive behavior can be conceptualized as the observable manifestation of aggression, which is defined as any act intended to cause harm, pain, or injury in another (Zirpoli, 2008). It is important to note that although aggressive behavior and
violence are often thought of as synonymous, they are not. Violence is a form of physical assault, whereas aggressive behavior is a broader construct that includes physical, verbal, psychological, and other means of causing harm, i.e. violence is but one form of aggressive behavior. Therefore, aggressive behavior does not necessarily include a physical component. This distinction is important because, although understanding aggressive behavior as a correlate or predictor of violence is
informative, non-violent aggressive behavior can still lead to negative outcomes and is equally deserving of attention. The study of aggressive behavior is important to the healthcare field due to the wide range of possible negative public health outcomes, including youth violence, increased medical resource use (e.g., emergency department, psychiatric, and critical care) and economic costs, and greater involvement in the criminal justice system
(Bastiaens & Bastiaens, 2006; Liu, 2004). A 2002 report from the World Health Organization found that 4,400 people die each year due to acts of violence (Krug et al., 2002),
underscoring the public health relevance of understanding and preventing aggressive behavior. The study of aggressive behavior is particularly relevant to the nursing profession. Since the pioneering days of Florence Nightingale, the work of nurses has evolved to often directly involve many forms of aggressive behavior, such as the identification of child abuse, the treatment of victims of
aggressive behavior in the emergency department, as well as the emotional and psychological care of sexual assault and rape victims. Workplace violence is also a well-documented phenomenon in healthcare settings, with physicians and nurses often the recipients and/or perpetrators (Duhart, 2001;
Gillespie, Gates, Miller, & Howard, 2010). Some studies have shown an increase of violence toward women in the healthcare field (Gillespie et al., 2010), making nurses especially vulnerable. Nursing involves the physical and emotional care of
individuals who may be momentarily unstable both physiologically and psychologically, therefore the work of nurses in administering care often causes pain and discomfort to the patient. The nature of nurses’ roles increases their likelihood of being threatened, verbally abused, or even physically assaulted while providing care. Nurses play an important role in assessing, preventing, and treating aggressive behavior among patients and families. For example, nurses develop and administer
psychiatric assessment and diagnostic instruments that can help detect the propensity toward aggressive behavior or related symptoms (e.g., emotional dysregulation), directly care for victims of aggressive behavior, and provide an environment that is safe and deliberately non-precipitating of aggressive behavior. The debate over the risk factors for aggressive behavior centers on whether it results more from psychosocial factors (e.g., parenting style, emotional trauma) or
biological factors (e.g., genetics, exposure to toxic chemicals). However, a common theme among all age groups appears to be the brain. For example, in children, the brain is not fully developed and is highly vulnerable to effects from negative stimuli (toxins, emotional trauma, etc.). In older adults, degeneration of the brain (from drugs, injury, or disease) may be a risk factor for aggressive behavior. Given that nurses are involved in caring for patients across the life span, the ongoing
dialogue about aggressive behavior, its etiologic and precipitating factors, as well as developmental manifestations is highly relevant in identifying, preventing, and treating symptoms. One of the unique characteristics of aggressive behavior that can make detection and treatment difficult is the variety of ways it can manifest across a person’s life span. In working with children and adolescents, nurses may be a part of the first-line of defense to help break this pattern and reduce aggressive
behavior in later life (Liu, 2004a; Liu & Wuerker 2005). We will explore the course of aggressive behavior throughout the life span below. Aggressive behavior during childhood is seen as a part of the normal developmental process (Greydanus, Pratt, Greydanus, & Hoffman, 1992). Before children develop verbal skills, aggressive behavior is manifested physically. Later on, verbal skills can be used for aggressive purposes, but also to diffuse
aggressive behavior by communicating needs that could not be expressed physically (Ferris & Grisso, 1996). Toddlers display aggressive behavior by crying, screaming, biting, kicking, throwing, and breaking objects (Achenbach, 1994;
Raine, Reynolds, Venebles, Mednick, & Farrington, 1998). Anger outbursts typically peak at 18 to 24 months and slowly decrease by age 5. It was found that the majority of children first reached the onset of aggressive behavior before age 2, at around 17 months of age
(Hay, Castle, & Davies, 2000; Keenan & Wakschlag, 2000; Tremblay et al. 1996). In addition, in children with developmental delay, a higher rate of
aggressive behavior and other externalizing behavior problems was found (Baker et al., 2003). As children mature and enter school, they may continue to display many of the same aggressive behaviors (e.g., crying, screaming, biting, kicking, throwing, and breaking objects) as during pre-school years. As these
school-age children begin to have more social interactions and develop more relationships, however, aggressive behavior towards peers may appear (Greydanus et al., 1992). In addition, behaviors such as teasing, irritability, bullying, fighting, and even cruelty to animals or fire-setting may be seen. Maternal reports of physical aggression between the ages of 2 and 11 years,
however, suggest that aggressive behavior may actually decrease over time (Tremblay et al., 1996). The same study found an increase in reports of indirect aggressive behavior from ages 4 to 11 years. This may be due to children’s increased use of verbal skills and a larger number social relationships and interactions during this timeframe. Although school-age children may display aggressive
behavior, multiple studies have found no evidence of the onset of physical aggression in children after the age of 6 years (Broidy et al., 1999; Nagin & Tremblay, 1999). This suggests that, for school-age children, aggressive behavior displayed at this developmental stage is
carried over from earlier ages, but does not begin during this stage. AdolescentsMoving forward, more serious aggressive behavior and even violence often appear during adolescence, resulting in an increase in injury or death, partly due to greater likelihood of weapon use (Berkowitz, 1993; Reiss & Roth, 1993). Early violence involves use of knives, with gun use increasing in the later years of adolescence. The increase in bodily strength and adoption of weapons may also empower adolescents to display a greater propensity towards directing aggressive behavior at authority figures (Callahan & Rivara, 1992; Johnston, O’Malley, & Bachman, 1993). Usually, adolescent aggressive behavior occurs in groups, including gang activities such as stealing or truancy (Lopez & Emmer, 2002). Peer relationships appear to play an important role in adolescent aggressive behavior. Displaying aggressive behavior may be a way to gain popularity or high social status by demonstrating power or control. Peer pressure may lead to displays of aggressive behavior out of fear of isolation or loss of social standing (Lopez & Emmer, 2002). There is also an increase in aggressive behavior between girls and boys as cross-gender peer relationships develop. As dating begins, aggressive behavior between genders increases and may include violent forms of aggressive behavior, like date rape and sexual assault. In addition, some adolescents may have partners and parent children, bringing the possibility of aggressive behavior manifested as child abuse or domestic violence. Many researchers have identified adolescent aggressive behavior as an important public health concern (Brener, Simon, Krug, & Lowry, 1999; Krug et al., 2002; Lowry, Powell, Kahn, Collins, & Kolbe, 1998). A cross-national study by the World Health Organization (WHO) using the Health Behaviour in School-Aged Children (HBSC) survey was conducted to compare the prevalence of violence across 35 nations (Pickett et al., 2005). Out of 161,082 student respondents, involvement in fighting per country ranged from 37–69% for boys and 13–32% for girls (Pickett et al., 2005). In addition, the prevalence of weapon-carrying varied from 10–21% for boys and 2–5% for girls (Pickett et al., 2005). There is a subset of aggressive behavior in adolescents, however, that appears in adolescence and then disappears in early adulthood. It has been termed adolescence-limited antisocial behavior (Moffitt & Caspi, 2001). In this case, previously healthy and normal youngsters engage in delinquent behavior during adolescence, but discontinue such behaviors upon entering adulthood. In this scenario, youngsters exhibiting adolescence-limited antisocial behavior are relatively common, temporary, and practically normative (Moffitt & Caspi, 2001). AdultsFrom adolescence to adulthood, aggressive behavior may escalate into more serious and violent acts, such as domestic violence, sexual abuse, child abuse, and homicide. Young adults (ages 18–24 years) are reported to have the highest homicide rate (U.S. Department of Justice, 2007). In 2009, the number of violent crime cases was 1,251,617, down 5.4% from 2008 and the number of homicides decreased 7.1% over the same time period to 14,558 (U.S. Department of Justice, 2009). Although this recent trend is encouraging, aggressive behavior and violence are still serious issues for adults. Child abuse is another important issue relevant to adult aggressive behavior. In 2008, according to a report on child maltreatment (defined as an act or failure to act which results in death, serious physical or emotional harm, sexual abuse, or exploitation), the rate of children who were subject to neglect or abuse was 1.03% (U.S. Department of Health & Human Services, 2008). Of these children, 28.9% were victims of physical, sexual, or psychological abuse (U.S. Department of Health & Human Services, 2008). Spousal abuse is a concern among adults, not only for the physical toll it can take but also for the emotional trauma involved. Although both genders can commit spousal abuse, men are responsible for a majority of incidents. For instance, 7.7% of all women in the United States reported being the victim of sexual violence, and about 22% of women were physically assaulted by a male partner at some point in their lives (Krug et al., 2002). Because nurses are the primary caregivers to these victims, they are active in helping them recover physically and emotionally. A unique subset of excessive aggressive behavior in adults is road rage. Although not directly classified in the DSM-IV, it can fall under the category of Intermittent Explosive Disorder. Road rage can describe any displays of anger while driving, although such displays are also referred to as “angry or aggressive driving” (Sharkin, 2004). Both aggressive driving and violent driving incidents have increased (Dukes, Clayton, Jenkins, Miller, & Rodgers, 2001). Age is the most important factor in aggressive driving incidents, with the majority of aggressive drivers being men between 18–26 years of age (Dukes et al., 2001). Some factors that may play a role include situational/environmental conditions (traffic, congestion, etc.), personality factors, or demographic variables (Sharkin, 2004). Older AdultsAs adults grow older, new situations come into play. Much of the research on aggressive behavior in older adults has been conducted on residents in nursing homes, likely due to the high prevalence of dementias in these populations. Aggressive behavior in nursing home residents may be directed towards other residents or caregivers (Rosen et al., 2008; Zeller et al., 2009). Aggressive behavior directed toward caregivers or healthcare professionals tends to be precipitated by personal care-related events. Specifically, aiding with showers, baths, and toileting may be perceived by the patient as a violation of personal space and body (Zeller et al., 2009). Behavioral disturbance is a common feature in dementia, often due to cognitive impairment, aphasia, agnosia, brain damage resulting in loss of inhibition and emotional dysregulation, and psychosocial difficulties. Patients experiencing difficulty verbally communicating their needs may display aggressive behaviors; thus, aggressive behavior may serve to protect themselves against actions they misperceive as threats (Talerico & Evans, 2000). A more serious form of aggressive behavior seen in older adults is homicide-suicide. Data suggests that the annual incidence of homicide-suicide is higher in adults 55 years and older compared to those younger than 55 years, with males more likely to perpetrate it than females (Cohen, Llorente, & Eisdorfer, 1998; Malphurs & Cohen, 2005). Homicide-suicide more typically occurs among couples than among unrelated individuals. Suicide, which may be conceptualized as a form of self-directed aggressive behavior, is disproportionately higher in geriatric populations than non-geriatric populations in the U.S. From 2000–2006, the rate of suicide among adults aged 65 years and older was 0.0148%, compared to a general population rate of 0.0109% (Centers for Disease Control & Prevention, 2009). Completed suicides among older Caucasian males are especially high, as much as five times greater than the national average (Conwell, Duberstein, & Caine 2002). Risk Factors for Aggressive Behavior Across the LifespanClearly, aggressive behavior can vary a great deal over the course of an individual’s life. Research suggests that this aggressive behavior develops as one of two types: that which emerges in childhood and progresses into adolescence and adulthood, and that which develops after childhood, often due to physical or emotional trauma, substance use, medical illness or brain injury. A summary of developmental-specific risk factors can be found in Table 1. Table 1Characteristics of and Risk Factors for Aggressive Behavior Across Different Age Groups
Aggressive Behaviors Emerging During ChildhoodMany theories about the emergence of aggressive behavior during childhood have also been posited to explain the occurrence of aggressive behavior in adolescents and adults. The social learning theory, which postulates that individuals learn aggressive behavior by observing others’ behavior, may explain aggressive behavior in children as well as other age groups. By observing aggressive behavior and its effect on obtaining a potential reward (e.g., resolution of a conflict, obtaining what they want), an individual may use similar behavior when confronted with a similar problem. In children, this is supported by evidence that exposure to family violence is often associated with displays of aggressive behavior among the children in that family (Herrera & McCloskey, 2003; Litrownik, Newton, Hunter, English, & Everson, 2003). Concern that media influences, such as violence in television or film, may be linked with increased aggressive behavior in individuals who watch those programs has found support in children specifically through use of longitudinal data (Huesmann, Moise-Titus, Podolski, & Eron, 2003). Another model, the social information processing (SIP) theory, proposes that people develop aggressive behavior after repeated exposure to specific social stimuli. For example, proactive aggression may occur after having received a reward following aggressive behavior. Furthermore, SIP posits that individuals who display aggressive behavior may be prone to misattributing motives, behaviors, and social cues, resulting in reactive aggression. Two studies found an increase in aggression scores in children with autism spectrum disorders (Dominick, Davis, Lainhart, Tager-Flusberg, & Folstein, 2007; Hartley, Sikora, & McCoy, 2008). SIP theory may partly explain this finding. More specific to the development of aggressive behavior in childhood is the question of “nature versus nurture,” which weighs whether and how much genetic/biological factors versus environmental factors contribute to aggressive behavior development. Some studies have found that psychosocial environmental factors, such as poor parental rearing, have a strong association with aggressive behavior in children (Blanz, Schmidt, & Esser; 1991; Deater-Deckard, Dodge, Bates, & Pettit, 1998; Fergusson, Horwood, & Lynskey; 1996, Liu, Cheng, & Leung, 2010), while others suggest a genetic basis for aggressive behavior (Baker, Raine, Liu, & Jacobson, 2008; Edelbrock, Rende, Plomin, & Thompson, 1995; Miles & Carey, 1997). Still others yield inconclusive results about the effect of genetics. It is likely that both genetics and environment are involved in the development of aggressive behavior in children. Increased exposure to air pollution or certain chemicals prenatally has been linked to increased aggressive behavior (Evans & Kantrowitz, 2002; Williams & Ross, 2007). Individuals displaying aggressive and/or violent behavior often have abnormal clinical findings on neurological examinations, EEG studies, and brain imaging scans (Raine, 2002; Raine, Lencz, Nihrle, LaCasse, & Colletti, 2000; Stoff & Cairns, 1996). Aggressive behavior may also be comorbid with impulsive behavior or attention deficit hyperactivity disorder (ADHD) (Hagerman, 1999). Furthermore, neurotransmitters may be an issue, as augmentation of serotonin was recently found to decrease aggressive behavior (Berman, McCloskey, Fanning, Schumacher, & Coccaro, 2009). Serotonin is a neurotransmitter found throughout the body, including the central nervous system (CNS) where it is thought to contribute to the feelings of happiness and well-being (Young, 2007). Sex hormones may be involved in the biological model of etiology. So-called “roid rage,” which attributes aggressive behavior to taking anabolic steroids has received significant attention in the popular media. A randomized controlled trial found that men who received testosterone injections had increased ratings of manic symptoms (Pope, Kouri, & Hudson, 2000). Health risk factors should not be overlooked (Liu, in press). For example, birth complications (e.g., anoxia, forceps delivery, etc.), in combination with other risk factors like poor parenting and disadvantaged family environment, are associated with the development of aggressive behaviors in childhood (Aresenault, Tremblay, Boulerice, & Saucier 2002; Hodgins, Kratzer, & McNeil, 2001, Liu & Wuerker, 2005). It is possible that birth complications may result in central nervous system damage, impairing proper brain function (Liu, Raine, Wuerker, Venables, & Mednick, 2009). Additionally, deficiencies in specific nutrients may hinder brain growth and development, potentially predisposing malnourished children to behavioral disturbance (Liu, Raine, Venables, Dalais, & Mednick, 2004). Tremblay (2010) notes the benefit of longitudinal studies, which may facilitate clarifying the complex interaction between genes and environmental factors. In the absence of such data, methods to prevent or treat aggressive behaviors may appear before the mechanisms are firmly determined (Tremblay, 2010). Aggressive Behavior Emerging in Adolescents, Adults, and Older AdultsAggressive behavior may also appear for the first time in adolescents, adults, or older adults. Aggressive behavior emerging after childhood may be conceptualized using similar theoretical approaches as in childhood aggression, such as the social learning theory or SIP theory. Aggressive behavior, however, that appears later in life may also be associated with increased substance abuse. Aggressive behavior may be used to obtain money to purchase substances or while under the influence of substances. Illicit drug use was found to be associated with increases in violence and violence-related injuries (Baskin-Sommers & Sommers, 2006; Vitale & de Mheen, 2006;). Of the substances linked to aggressive behavior, alcohol appears particularly noxious. Alcohol is linked with violence including intimate partner violence (Bye, 2007; Lipsky, Caetano, Field, & Larkin, 2005). For example, alcohol was present in 63% of partner violence incidents, 39–45% of murders, 32–40% of sexual assaults, and 45–46% of physical assaults (Greenfeld & Henneberg, 2001). Level of intoxication may also contribute. Individuals involved in incidents of severe aggressive behavior may be more intoxicated that individuals involved in less severe incidents (Graham & Wells, 2001). Alcohol, however, has not been conclusively shown to cause aggressive behavior. Alcohol may interfere with self-control. Or perhaps individuals who use aggressive behaviors consume alcohol more frequently than people who do not. Recent data has examined the impact of traumatic brain injury (TBI) and an increased likelihood to develop aggressive behavior following childhood. For example, aggressive behavior was a prevalent symptom of TBI (Baguley, Cooper, & Felmingham, 2006; Cole et al., 2008; Tateno, Jorge, & Robinson, 2003). The initial injury may damage areas in the brain responsible for managing aggression and impulse control, particularly the frontal lobes (Tateno et al., 2003). It is not known, however, whether TBI may have other effects resulting in aggressive behavior that brain scans may not detect. The onset of dementia may contribute to the manifestation of aggressive behavior in older adults due to decrements in intellectual functioning, memory, and reasoning (Brodaty & Low, 2003; Patel & Hope, 2004). Further, patients with neurodegenerative diseases may suffer from delusions or hallucinations, making aggressive behavior more likely when they misperceive a threat (Aarsland & Cummings, 1996; Patel & Hope, 2004). Kunik and colleagues (2010) detailed aggressive behavior risk factors in persons with dementia and found depression, physical pain, and poor interrelationships between the patient and caregiver significantly associated with greater incidence of aggressive behavior. Other disorders associated with aggressive behavior are bipolar disorder, depression, and post-traumatic stress disorder (Garno, Gunawardane, & Goldberg, 2008; Latalova, 2009; McGirr & Turecki, 2007; Taft, Vogt, Marshall, Panuzio, & Niles, 2007; Taten et al., 2010; Treuting & Hinshaw, 2001). These associations not only apply to older adults but to all adults in general. For those with bipolar disorder, which is characterized by alternating episodes of mania or depression, aggressive behavior may occur during mania. In patients with depression or in a depression episode of bipolar disorder, self-directed aggression may manifest. Post-traumatic stress disorder often results from psychological trauma and affects the individual’s ability to cope with anxiety. Aggression against others may serve as a way to deal with the stress. It is unclear if a causal relationship exists. Aggressive behavior in older populations has been associated with premorbid personality dysfunction, illness progression, verbal communication impairments, and misattributions of behaviors from caregivers (e.g., perceiving acts of personal care, such as hygiene, as threats) (Pulsford & Duxbury, 2006; Rayner, O’Brien, & Schoenbachler, 2006; Shub, Ball, Abbas, Gottumukkala, & Kunik 2010; Talerico, Evans & Strumpf, 2002). In addition, although the reasons behind homicide-suicide are often unclear, a number of factors may contribute. For example, the perpetrator was more likely a caregiver for the victim (Malphurs & Cohen, 2005). Similarly, the perpetrator more likely had a history of domestic violence (Malphurs & Cohen, 2005). Other factors include marital and family conflict, pending separation, and life-event stressors (Cohen, 2000; Malphurs, Eisdorfer, & Cohen, 2001; Rosenbaum, 1990). In some instances caregivers recognize their own failing health and do not want to leave the spouses unattended. For example, increased dependency of the care-recipient and greater functional impairment of the caregiver can increase strain and burden which is associated with increased depression symptoms (Schulz & Beach, 1999). Finally, risk factors for suicide among older adults are well researched and generally considered complex due to the multiplicative effects of physical and mental disabilities that are increasingly common in late life. Psychiatric disorders, including major depression and psychotic illness, significant physical illness, perceived burdensomeness, lack of social support, and living alone all appear to significantly increase the risk of suicide in this population (Garand, Mitchell, Dietrick, Hijjawi, & Pan, 2006; Jahn, Cukrowicz, Linton, & Prabhu, 2010; Mitty & Flores, 2008). This complexity may make it difficult to implement prevention plans. Consequences of Aggressive BehaviorAfter it appears, aggressive behavior can have profound health and psychosocial effects on the perpetrator, victim, as well as bystanders. Children exposed to family violence may be more likely to express problem behaviors themselves (Litrownik et al., 2003, Liu, 2004b). Infants who live in families that experience aggressive behavior and violence may suffer from irritability, sleep disturbances, emotional distress, and somatic complaints (Osofsky & Scheeringa, 1997; Zeanah & Scheeringa, 1997). Children living in homes with handguns are differentially at risk for increased injury or death than children not living in homes with firearms (Richmond, Schwab, & Branas, 2002). Additionally, when children enter school, exposure to violence may result in misattribution biases toward inferring negative intent from neutral or unclear social cues, which can impair one’s ability to form healthy, functional relationships (Dodge, Pettit, & Bates, 1998). As aggressive children grow older and enter adolescence, they become at greater risk for anxiety, depression, and suicidal behavior (Brown & Finkelfor, 1986; Lewis, 1992; Rosenberg & Rossman, 1998). Aggressive behavior casts a notable economic toll (Barling, Rogers, & Kelloway, 2001; O’Leary-Kelly, Griffin, & Glew, 1996; Schat & Kelloway, 2000). The total financial cost of violence in the United States was estimated to be $70 billion per year, with $64.4 billion in lost productivity and $5.6 billion in medical care (Corso, Mercy, Simon, Finkelstein, & Miller, 2007). While victims of aggressive behavior are at risk for psychological and emotional traumatic reactions as well as psychiatric disorders, such as panic attacks, phobias, and depression, aggressors also face negative consequences. This includes increased risk of legal punishment and, in some cases, imprisonment. In turn, the violent nature of the prison environment often further reinforces aggressive behavior in the offender, perpetuating a cycle that can be difficult to break. Prevention and Intervention: A Three-Pronged ApproachDue to these significant consequences of aggressive behavior, steps for prevention and treatment must be taken to mitigate these harmful effects. Understanding the risk factors for aggressive behavior is vital to effective prevention and intervention. Many psychological treatments for aggressive behavior have been included as part of larger interventions for anger. While anger does not always lead to aggressive behavior, anger management interventions often focus on reducing aggressive behavior as an important outcome of interest. Effective techniques supported by the literature include cognitive/skill-training components (e.g., identifying and correcting misattributions; reframing negative cognitions into more neutral or positive cognitions; using forethought and planning behaviors rather than acting impulsively; developing problem solving skills; using perspective-taking to consider others’ views; self-monitoring to increase awareness of one’s emotions and potential reactions) as well as behavioral components (e.g., finding non-aggressive means for communicating; non-aggressive methods of diffusing anger, emoting and venting frustrations; using relaxation techniques) (Chemtob, Novaco, Hamada, & Gross, 1997; Deffenbacher, Dahlen, Lynch, Morris, & Gowensmith, 2000; Deffenbacher & McKay, 2000; Del Vecchio & O’Leary, 2004). Pharmacologic treatments with documented efficacy in children and adult populations include mood stabilizers, antipsychotics, selective serotonin reuptake inhibitors, beta blockers, and anticonvulsants (Coccaro & Siever, 2002; Findling, 2003). We recommend a three-pronged approach for the prevention and intervention of aggressive and violent behavior. The first involves the use of primary prevention programs focusing on the prenatal and perinatal periods of birth. Prenatal nurses and nurse midwifes can provide good prenatal care and screen for risk factors. In addition, they can educate mothers on proper prenatal care, including the importance of nutrition and the avoidance of smoking, drinking, or other harmful activities. For instance, supplementation with different nutrients or micronutrients (e.g., thiamine, lithium, and tryptophan) has been shown to lead to decreased aggressive behavior (Werbach, 1992). Postpartum nurses can instruct parents about proper parenting skills and the importance of breastfeeding. However, there is conflicting evidence about whether breastfeeding protects against behavior problems or not (Kramer, 2010; Kramer et al., 2008; Oddy et al., 2010). The second approach could target prevention efforts toward vulnerable populations, such as pregnant teenagers and at-risk families (e.g., those with a history of violence). Again, patient education about the damage of prenatal smoking or drinking may be beneficial. School nurses can monitor child growth and development. Additionally, they can work with teachers to detect the warning signs of aggressive behavior and explain emotion management techniques. School nurses can also instruct nurses about different techniques to reduce aggressive behavior in children and adolescents that already exhibit it. For example, massage therapy helped decrease aggressive behavior in preschool children (von Knorring, Soderberg, Austin, & Uvnas-Moberg, 2008). Separate case reports have suggested that meditation, relaxation breathing exercises, and music therapy could be effective in lessening aggressive behavior (Birnbaum, 2005; Gaines and Barry, 2008; Rickson and Watkins, 2003). However, in-classroom use of restraints was not found helpful, as it actually increased problem behaviors (Magee and Ellis, 2001). Community health and public health nurses can help at-risk families through enrollment in school-based or community-based prevention programs or family-strengthening programs, which have been shown to be effective (Fields & McNamara, 2003; Kumpfer & Alvarado, 2003; Mytton, DiGuiseppi, Gough, Taylor, & Logan, 2006). The Head Start program, when incorporating an emotion-based prevention program, led to increases in emotion knowledge and regulation and decreases in aggressive behavior, negative emotion expressions, and negative peer and adult interactions (Izard et al., 2008). As demonstrated by Olds and colleagues (1998), nurses can be directly involved in prevention through home-based nursing visits early in childhood, which may lead to reduced aggressive behavior later. In addition, removing guns and other weapons in the home could improve safety and prevent violence from occurring. Finally, the third approach involves the actual treatment of those individuals that develop aggressive behavior. Psychiatric nurses are very involved in the traditional methods of intervention, such as psychotherapy or psychopharmacology. Cognitive behavioral therapy (CBT) attempts to address dysfunctional emotional, behavioral, and cognitive problems by helping patients adopt healthier behaviors and thinking patterns. Studies have shown the effectiveness of CBT in reducing anger and aggressive behavior in children, adolescents, and adults (Beck & Fernandez, 1998; Rowand, Smith, Miller, & Brownell, 1999; Sukhodolsky, Kassinove, & Gorman, 2004). In the treatment of older adults, geriatric nurses need to be aware of the special issues involved. Care must be taken when attending to patients with dementia, who might perceive care as a threat. A person-centered approach has been effective in decreasing aggressive behavior in dementia patients (Enmarker, Olsen, & Hellzen, 2011). The treatment of behavioral disturbances, including aggressive behavior, in patients with dementia often involves pharmacotherapy with atypical antipsychotic medications. Equivalent non-pharmacological treatments may include behavior modification techniques to help patients learn non-aggressive strategies for communicating. Observing early interactions that escalate to aggressive behavior in a person of risk can also be important. A study by Landreville and colleagues (2006) reviewed the effectiveness of different non-pharmacological techniques. Special staff training, removal of negative stimuli, structured activities, and special care units showed some effectiveness in reducing aggressive behavior (Landreville et al., 2006). Although these programs may not work in all situations, nurses can experiment with them to see which initiatives are effective for individual patients. Overall, in the care of older adults, nurses and caregivers must explore the needs of their patients by open communication between the caregivers, patients, and their family members. Nurses may be particularly effective in the implementation of these behavioral strategies as they have continual contact with patients and are involved with care giving throughout the patient’s day. Nurses are important for risk assessment, as they have the opportunity to predict whether future aggression is likely based on past behaviors (Irwin, 2006). Not only are nurses likely to be very familiar with a patient’s given “triggers” for aggressive behavior, their ongoing involvement with patients means they have ample opportunities to teach skill-building for reducing aggressive behavior. For the actual treatment of aggressive behavior, medication is an effective tool. For inpatients, the quality of the nurse-patient relationship appears to be the most significant determinant of whether patients decide to take their medications (Irwin, 2006). Therefore, nurses have an important part to play in prevention, risk assessment, and treatment of aggressive behavior. ConclusionThe concept of aggressive behavior across the life span is very complex. An overarching theme appears to involve both risk factors that precipitate and increase the predisposition towards aggression as well as situations that actually elicit the aggression. For instance, early exposure to violence, toxin exposure, drug use, etc. may potentially be risk factors for aggression and predispose people to behaving aggressively. However, specific situations may actually draw out that aggressive behavior. This appears to apply to all age groups. For example, in childhood, aggressive behavior may bring rewards, such material goods or control over a situation. In adolescence, aggressive behavior may result from increased peer pressure or may serve as a means to resist authority. In adulthood, increased responsibility (taking care of family or earning an income), may bring targets of aggressive behavior such as domestic violence. In older adults, invasion of personal space may trigger aggression and diminishing physical skills may be a reason to contemplate suicide. These are just some scenarios in which aggressive behavior may be drawn out. Effective prevention strategies may need to reduce risk factors as well as mitigate the ability of those situations to elicit aggression. This is essential, because aggressive behaviors pose important individual and public health risks. As the medical caregivers who have the most interaction with aggression victims and perpetrators, nurses play a central role in the prevention and intervention of aggressive behavior. A better understanding of the etiology and meaning of aggressive behavior may lead to better treatment options and, ultimately, better outcomes. Aggressive behavior has been linked to both psychosocial and biological factors, and greater research is needed to definitively identify all of the factors that can give rise to aggressive behavior. Aggressive behavior is unique in that its causes and manifestations can vary across different age groups. Therefore, it is imperative that nurses understand these age-related differences in order to successfully tailor and develop effective prevention and intervention plans.
