Washington DC : National Academies Press US ; Sep Bullying behavior is a serious problem among school-age children and adolescents; it has short- and long-term effects on the individual who is bullied, the individual who bullies, the individual who is bullied and bullies others, and dj pone homework 02 bystander present during the bullying event. In this chapter, the committee presents the consequences of bullying behavior for children and youth.

As referenced in Chapter 1bullying can be either direct or indirect, and children and youth may experience different types of bullying. Specifically the committee examines physical including neurobiologicalmental, and behavioral health consequences.

The committee also examines consequences for academic performance and achievement and explores evidence for some of the mechanisms proposed for the psychological effects of bullying. When applicable, we note the limited, correlational nature of much of the available research on the consequences of bullying. Mounting evidence on bullying has highlighted the detrimental effects of being bullied on children's health and behavior Gini and Pozzoli, ; Lereya et al.

In this section, the committee reviews the research on physical, psychosocial, and academic achievement consequences for those children and youth who are bullied. Being bullied makes young people incredibly insecure: When you're being bullied, you can feel constantly insecure and on guard. Even if you're not actively being bullied, you're aware it could start anytime. It has a big mental and emotional impact—you feel unaccepted, isolated, angry, and withdrawn.

You're always wondering how you can do better and how you can escape a bully's notice. You're also stunted dj pone homework 02 of the constant tension and because maybe you forego making certain friendships or miss out on taking certain chances that could actually help your development. See Appendix B for additional highlights from interviews. The physical health consequences of bullying can be immediate, such as physical injury, or they can involve long-term effects, such as headaches, sleep disturbances, or somatization.

In one of the few longitudinal studies on the physical and mental effects of bullying, Bogart and colleagues studied 4, children and their parents from three urban locales: Birmingham, Alabama; 25 contiguous school districts in Los Angeles County, California; and one of the largest school districts in Houston, Texas.

Bogart and her team were interested in the cumulative effects of bullying on an individual, dj pone homework 02. They collected data when the cohort was dj pone homework 02 fifth grade todj pone homework 02, seventh grade toand tenth grade to Data consisted of responses to the Peer Experience Questionnaire, the Pediatric Quality of Life Inventory with its Psychosocial Subscale and Physical Health Subscale, dj pone homework 02, and a Self-Perception Profile.

The Physical Health Subscale measured perceptions of physical quality of life. Bogart and colleagues found that children who were bullied experienced negative physical health compared to dj pone homework 02 peers, dj pone homework 02. Among seventh grade students with the worst-decile physical health, 6.

These effects were not as strong when students were in tenth grade. Limitations to this study were that physical health was measured by participants' perceptions of their health-related quality of life, rather than by objectively defined physical symptoms.

It is critical to understand that this study, or other studies assessing correlations between behavior and events, cannot state that the events caused the behavior. Future research might build on this large multisite longitudinal study and obtain more in-depth evidence on individuals' physical health as a consequence of bullying. In their study of 2, twins reared together and separately as a part of the Environmental Risk E-Risk Longitudinal Twin Study, Baldwin and colleagues found that children who had experienced chronic bullying showed greater adiposity subsequently, but not at the time of victimization.

An important future direction for research is to gather more information on physical consequences such as elevated blood pressure, dj pone homework 02, inflammatory markers, and obesity in light of work showing effects on these outcome of harsh language by parents and other types of early life adversity Danese and Tan, ; Danese et al.

Most of the extant evidence on the physical consequences—somatic symptoms in particular—of bullying pertains to the individual who is bullied. The emotional effects of being bullied can be expressed through somatic disturbances, which, similar to somatization, are physical symptoms that originate from stress or an emotional condition. Common stress or anxiety-related symptoms include sleep disorders, gastrointestinal concerns, headaches, palpitations, and chronic pain.

The relationship between peer victimization and sleep disturbances has been well documented Hunter et al. For instance, Hunter and colleagues examined sleep difficulties feeling too tired to do things, had trouble getting to dj pone homework 02, and had trouble staying asleep among a sample of 5, Scottish adolescents.

One limitation of this study is that it was based on self-reports, which have sometimes been criticized as being subject to specific biases. Patients with insomnia may overestimate how long it takes them to fall asleep Harvey and Tang, Another limitation is that the study included young people at different stages of adolescence. Sleep patterns and sleep requirements vary across the different stages of adolescence. A recent meta-analysis based on 21 studies involving an international sample ofchildren and adolescents examined the association between peer victimization and sleeping problems.

A broader focus on peer victimization was used because of the definitional issues related to bullying. Moreover, the relationship between peer victimization and sleeping problems was stronger for younger children than it was for older children van Geel et al.

This study was based on cross-sectional studies that varied widely in how peer victimization and sleeping problems were operationalized and thus cannot make any claims about causal relations between peer victimization and sleeping problems. Knack and colleagues a posited that bullying results in meaningful biological alterations that dj pone homework 02 result in changes in one's sensitivity to pain responses, dj pone homework 02.

A recent meta-analysis by Gini and Pozzoli concluded that children and adolescents who are bullied were at least twice as likely to have psychosomatic disturbances headache, stomachache, dizziness, dj pone homework 02, bedwetting, etc.

Although the use of self-report measures are very common in bullying research and are usually considered to be valid and reliable Ladd and Kochenderfer- Ladd,their use requires adequate self-awareness on the part of the respondent, and some children who are bullied may be in denial about their experience of having been bullied.

There is also evidence of gender dj pone homework 02 in the physical effects of being bullied. For example, Kowalski and Limber examined the relation between experiences with cyberbullying or traditional bullying i. Students were asked how often in the past 4 weeks they experienced 10 physical health symptoms, with scores across these 10 symptoms averaged to provide an overall health index higher scores equal more health problems, dj pone homework 02.

A limitation of this study is that it is correlational in nature and the authors cannot conclude that being a victim of traditional bullying caused the psychological or physical problems.

In summary, it is clear that children and youth who have been bullied also experience a range of somatic disturbances. There are also gender differences in the physical health consequences of being bullied.

Psychological and physical stressors, such as being the target of bullying, activate the stress system centered on the hypothalamic-pituitary-adrenal HPA axis Dallman et al. The role of HPA and other hormones is to promote adaptation and survival, but chronically elevated hormones can also cause problems. Stress has ubiquitous effects on physiology and the brain, dj pone homework 02 levels of many hormones and other biomarkers, and ultimately affects behavior.

Therefore, dj pone homework 02, both a general understanding of stress during early adolescence and, where known, specific links between stress and bullying can provide insight into the enduring effects of bullying.

The dj pone homework 02 of the stress hormone cortisol have been shown to change in targets of repeated bullying, dj pone homework 02, with being bullied associated with a blunted cortisol response Booth et al. To the committee's knowledge, no study has examined bidirectional changes in cortisol, although there is evidence to suggest that cortisol is typically elevated immediately following many types of stress and trauma but blunted after prolonged stress Judd et al.

Kliewer did find that cortisol increased from pre-task to post-task i. However, in these studies, the immediate effect of being bullied on stress reactivity was not examined. In contrast, Ouellet-Morin and colleagues and Knack and colleagues b did not find an increase in dj pone homework 02 in bullied youth following a psychosocial stress test but rather found a blunted pattern of response after the test had concluded see Figures and In order to test whether, in the short-term, bullying produces an increase in cortisol, whereas in the long-term it is associated with a blunted cortisol response as seen with other types of psychosocial stressors; Judd et al.

The importance of this future work notwithstanding, there is evidence to support a finding that when stress becomes prolonged, the stress hormone system becomes hypofunctional and a blunted stress response results McEwen, Cortisol reactivity for victimized and nonvictimized adolescents during the Trier Social Stress Test.

SOURCE: Adapted from Knack et al. SOURCE: Adapted from Ovellet-Morin et al. When stress becomes prolonged, the stress hormone system becomes hypofunctional and a blunted stress response results Knack et al. That is, the elevation in cortisol in response to stress fails to occur.

Cortisol has many functions and serves to regulate myriad biological systems; a blunted stress response compromises the orchestration of cortisol's biological functions. The critical importance of the massive over-activation of the stress system producing a blunted stress response is clinically relevant since it is associated with posttraumatic stress disorder and other psychiatric disorders Heim et al.

It is also relevant for understanding an individual's inability to self-regulate and cope with stress. Prolonged stress also disrupts the circadian or daily rhythm of cortisol, which is normally elevated in the morning and slowly decreases over the day to result in low levels at bedtime Dj pone homework 02 et al. An altered circadian rhythm results not only in difficulty awaking in the morning but also in difficulty falling asleep at night.

It can cause profound disruption in sleep patterns that can initiate myriad additional problems; sleep deficits are associated with problems with emotional regulation, dj pone homework 02, learning, mood disorders, and a heightened social threat detection and response system McEwen and Karatsoreos, Recent research suggests that the consolidation of memories 2 one learns each day continues during sleep Barnes and Wilson, ; Shen et al.

Sleep disturbances disrupt memory consolidation, and studies in animals suggest stress during learning engages unique neurochemical and molecular events that cause memory to be encoded by some unique mechanism Baratta et al, dj pone homework 02. Although victims of bullying have sleep problems Miller-Graff et al. Dj pone homework 02, these correlations between being a target of bullying and physiological problems may highlight important interactions between events and outcome, dj pone homework 02, but it is also likely that unidentified variables might be the critical causal factors.

It is also noteworthy that the HPA axis showed heightened responsiveness during the peak ages of bullying Blakemore, ; Dahl and Gunnar, ; Romeo, ; Spear, For example, cortisol response characteristics in children are such that, when cortisol is activated, the hormonal response is protracted and takes almost twice as much time to leave the blood and brain compared to adults Romeo, The circadian rhythm of cortisol also seems altered during early adolescence, most notably associated with morning cortisol levels, with levels increasing with age and pubertal development Barra et al.

Animal models suggest that the extended cortisol response begins in pre-puberty and indicate that recovery from stressful events is more challenging during this age range Romeo, Emotional regulation, including a person's ability to recover from a traumatic or stressful event, involves being able to regulate or normalize stress hormone levels. Specifically, it is well documented in the human and animal research literature that a sensitive caregiver or a strong support system can greatly dampen the stress system's response and actually reduce the amount of stress hormone released, dj pone homework 02, as well as shorten the amount of time the stress hormones circulate within the body and brain.

This results in dramatic decreases in stress-related behavior Gee et al. The social cues actually reduce stress by reducing the activation of the stress system, dj pone homework 02, or HPA axis, at the level of the hypothalamus Hennessy et al. The social stimuli that buffer children as they transition into adolescence appear to begin to have greater reliance on peers rather dj pone homework 02 on the caregiver Hostinar et dj pone homework 02. Other physiological effects of stress include the activation of the immune system by bullying-induced stress Copeland et al.

Other hormones and physiological mechanisms are also involved in the stress activation response. For example, cortisol is associated with an increase in testosterone, the male sex hormone associated with aggression in nonhuman animals and with dominance and social challenge in humans, particularly among boys and men Archer, In fact, in rodents the combined assessment of testosterone and cortisol provides more predictive value of behavioral variability McCormick and Mathews, compared to controls Márquez et al.

In humans, there is increasing evidence supporting an interaction between testosterone and cortisol in the prediction of social aggression see Montoya et al. In a study of year-olds, Vaillancourt and colleagues found that testosterone levels were higher among bullied boys than nonbullied boys, but lower among bullied girls than nonbullied girls.

The authors speculated that the androgen dynamics were possibly adrenocortical in origin, highlighting the need to examine testosterone and cortisol in consort. To date, researchers have only investigated cortisol response to being bullied Kliewer, ; Knack et al. There are no studies examining these two important hormones together in relation to bullying perpetration or to being bullied.
