Self-esteem level of Brazilian teenagers victims of bullying and its relation with the need of orthodontic treatment

Nível da autoestima de adolescentes brasileiros vítimas de bullying e sua relação com a necessidade de tratamento ortodôntico

ABSTRACT

Objective:

The aim of this study was to analyze self-esteem among Brazilian adolescents and also verify possible associations between the variables: the need for orthodontic treatment and bullying.

Methods:

The cross-sectional, population-based epidemiological study consisted of a sample composed of adolescents from 11 to 16 years of age, enrolled in the public school system of a medium-sized municipality in the northwest of the State of São Paulo, Brazil. A dental examination was performed using the Dental Aesthetic Index (DAI) in order to verify the need for orthodontic treatment and a self-administered questionnaire containing the Global Self-Evaluation (GSE) indices to identify the level of self-esteem and Kidscape in order to detect bullying. Data analysis was performed using descriptive statistics, association analysis and multivariate logistic regression.

Results:

A total of 815 adolescents participated in the study. There was a statistically significant association between self-esteem and the variables: sex (p <.0001), willingness to straighten teeth to improve appearance (p = 0.0006), bullying victim (p <.0001), frequency of bullying = 0.0111) and consequences of bullying (p <.0001). A significant risk factor for non-white adolescents' very negative self-esteem (OR = 1.914) was present together with bullying victims who had had negative consequences after the episode (OR = 3.343).

Conclusion:

There was an association between the self-esteem and bullying variables. Those who reported negative consequences on bullying were three times more likely to present very negative self-esteem, and the chances of non-white adolescents to show negative self-esteem were almost twice as high. There was no statistically significant association between self-esteem and the need for orthodontic treatment.

RESUMO

Objetivo:

Analisar o nível da autoestima de adolescentes brasileiros e verificar as possíveis associações de desfecho com a necessidade de tratamento ortodôntico e bullying.

Métodos:

Estudo epidemiológico transversal de base populacional. A população foi composta por adolescentes de 11 a 16 anos, matriculados na rede pública de ensino de um município de médio porte do noroeste paulista. Foi realizado um exame bucal utilizando o índice Dental Aesthetic Index (DAI), para verificar a necessidade de tratamento ortodôntico, e um questionário autoaplicável, contendo os índices Global Self-Evaluation (GES), para identificar o nível de autoestima, e o Kidscape, para detecção de bullying. A análise dos dados foi feita utilizando estatística descritiva, análises de associação e regressão logística multivariada.

Resultados:

No total, 815 adolescentes participaram da pesquisa. Houve associação estatisticamente significante entre autoestima e as variáveis: sexo (p<.0001), vontade de corrigir os dentes para melhorar a aparência (p=0.0006), vítima de bullying (p<.0001), frequência com que sofreu bullying (p=0.0111) e consequências do bullying (p<.0001). Apresentaram-se como fator de risco significante para uma autoestima muito negativa a cor da pele não branca (OR=1.914) e vítimas de bullying que tiveram consequências negativas após o episódio (OR= 3.343).

Conclusão:

Houve associação entre as variáveis autoestima e bullying. Aqueles que relataram consequências negativas sobre o bullying apresentaram chances três vezes maiores de ter autoestima muito negativa, já as chances dos adolescentes com cor da pele não branca foram quase duas vezes maiores. Não houve associação estatisticamente significante entre autoestima e necessidade de tratamento ortodôntico.

INTRODUCTION

The different ways of violence expressions affect society as a whole, its different sectors and social levels. The child and the adolescent are more susceptible to violent situations in which they are exposed in the social, family or school environment11 Cavalcanti AL. Maxillo facial injuries in victims of violence at school environment. Ciênc Saúde Coletiva. 2009;14(5):1835-42. doi: 10.1590/S1413-81232009000500025
https://doi.org/10.1590/S1413-8123200900...
. The phenomenon known as bullying or bullying among peers or peers in school-age children is considered a subtype of violence. It can be defined as a specific form of aggressive behavior in which the student is repeatedly exposed to negative actions, by one or more students22 Olweus D. Bullying at school: basic facts and effects of a school based intervention program. J Child Psychol Psychiatry. 1994;35:1171-90. doi: 10.1111/j.1469-7610.1994.tb01229.x
https://doi.org/10.1111/j.1469-7610.1994...
. One of its main characteristics is an imbalance in real or perceived power between the victim and the aggressor. It can be manifested in different forms of aggression: direct (physical and verbal aggression) or indirect (social exclusion, gossip and isolation), causing damage to the victim33 Fekkes M, Pijpers FI, Verloove-Vanhorick SP. Effects of antibullying school program on bullying and health complaints. Arch Pediatr Adolesc Med. 2006;160(6):638-44. doi: 10.1001/archpedi.160.6.638

.

Bullying victims often develop behavioral and emotional problems, such as high levels of stress, decrease or loss of self-esteem, impaired learning and academic performance, anxiety, depression and, in more extreme cases, these problems lead to suicide22 Olweus D. Bullying at school: basic facts and effects of a school based intervention program. J Child Psychol Psychiatry. 1994;35:1171-90. doi: 10.1111/j.1469-7610.1994.tb01229.x

Self-esteem can be considered the most critical variable which affects the successful insertion of an adolescent into their social relationships. It is said to be an important adolescence mental health indicator66 Bandeira, CM, Hutz CS. Implications of bullying in adolescents' self-esteem. Psicol Esc Educ. 2010;14:131-8. doi: 10.1590/S1413-85572010000100014

, since mechanisms which distort the communication of the adolescents' thoughts and feelings can be developed , imparing their social integration with other adolescents77 Costa ACG. Protagonismo juvenil: adolescência, educação e participação democrática. Salvador: Fundação Odebrecht; 2000..

Aesthetic beauty standards are strongly related to the level of self-esteem. Malocclusion is considered a deviation from the aesthetic pattern in society, and not a disease in itself, and it can be defined as the anomaly in the development of dental arches, resulting in aesthetic and / or functional problems88 Campos FL, Vazquez FL, Cortellazzi KL, Guerra LM, Ambrosano GMB, Meneghim MC, et al. A má oclusão e sua associação com variáveis socioeconômicas, hábitos e cuidados em crianças de cinco anos de idade. Rev Odontol UNESP. 2013;42:160-6.

Although many studies have reported the problem of bullying in schoolchildren, no national study has researched the association of this phenomenon using self-esteem and malocclusion variables. Therefore, the aim of the present study was to analyze the level of self-esteem in adolescents of the public school system as well as to verify the possible associations of orthodontic treatment need and bullying.

METHODS

Study design

This is a cross-sectional epidemiological study carried out with adolescents of both sexes, enrolled in public schools, in a medium-sized municipality located in the northwest of the State of São Paulo, Brazil, in 2014.

A total of 19 schools participated in the study (out of the 20 elementary schools in the urban area), and one school did not consent to participate in the research during the time available for data collection (N = 4.283). The sample consisted of adolescents aged from 11 to 16 years-old, students from 7th, 8th and 9th grade, so that they could answer the self-administered questionnaire. Exclusion criteria were: adolescents whose parents did not authorize the exams, adolescents who had parents' authorization but did not want to participate in the survey, and those who were not present on the three dates scheduled for the exams. The final sample consisted of 815 adolescents (19.03%).

Ethical aspects

This study was approved by the Research Ethics Committee under protocol number FOA-01080/2011. The adolescents were examined only when the consent term had been signed by the parents or guardians. The data collection began after the authorization of the regional education leader and the school principals involved in the research.

Data collection

Initially, the subjects answered the self-administered questionnaire containing the Global Negative Self-Assessment scale to identify the level of self-esteem and the Kidscape questionnaire to assess bullying.

The Global Negative Self-Evaluation1414 Alsaker F, Olweus D. Global self-evaluations and perceived instability of self in Norwegian preschoolchildren and schoolchildren. J Early Adolesc 1986;6:269-78. doi: 10.1111/j.1467-9450.1993.tb01100.x
https://doi.org/10.1111/j.1467-9450.1993...
instrument consists of a six-item scale, each one presenting six response alternatives, which are quantified in ascending order (1 to 6), following the scale arrangement. Through this instrument, it is possible to classify self-esteem in four categories: 1-1.69, very negative self-assessment; 1.7 - 2.69, low negative self-assessment; 2.7 - 3.99, negative self-assessment; 4.0-6.0, very negative self-assessment. The results were dichotomized in low negative self-esteem (1-2.69) and very negative self-esteem (2.7-6) to facilitate data analysis.

In order to assess bullying among schoolchildren, the research used a British-English instrument named KIDSCAPE which prevents bullying and child sexual abuse1515 Kidscape: preventing bullying, protectin children [cited 20 Maio 2015]. Available from: <http://www.kidscape.org.uk>.
http://www.kidscape.org.uk...
. The following questions were considered for this evaluation: frequency of bullying, its consequences, the type of intimidation, the sex of the perpetrator and whether the victim, himself, has ever been a bully.

Afterwards, an oral exam was performed following the World Health Organization requirements and using the Dental Aesthetic Index (DAI), an instrument proposed by Cons et al.1616 Cons NC, Jenny J, Kohout FJ, Songpaisan Y, Jotikastira D. Utility of the dental aesthetic index in industrialized and developing countries. J Pub Health Dent. 1989;49:163-6. doi: 10.1111/j.1752-7325.1989.tb02054.x
https://doi.org/10.1111/j.1752-7325.1989...
which evaluates the individual's aesthetic commitment, besides occlusion. After the examination, the occlusal condition is categorized into: no abnormality or mild malocclusion (no need for treatment), definite malocclusion, severe malocclusion and very severe or disabling malocclusion. For the data analysis, the results of this index were dichotomized as follows: need of treatment (> 25 - mild, moderate and severe) and without need of treatment (≤25 - normal).

The oral examination and the questionnaire application were performed in the teaching institution by a previously calibrated single researcher and specialist in orthodontics. The calibration of the team (examiner and note-taker) and the methodological adjustments were made in the pilot study preceding the research. In this stage, 26 participants were examined within 15 days and excluded from the final sample . Intra-examiner diagnostic agreement was measured by the kappa statistical test and considered optimal (kappa = 0.91).

Data analysis

Data were analyzed using the SAS for Windows, version 9.3. The chi-square test or Fisher's test was used at a 5% level of significance in order to verify the association between self-esteem (negative and very negative) with the following variables: gender, age, skin color, desire to correct their teeth, bullying, frequency with which they have been bullied, sex of perpetrator, type of bullying suffered and whether the victim has already been a bully. The multivariate analysis was performed through logistic regression considering self-esteem as a response variable and the others as explanatory. The variables which presented statistical significance were introduced into the model and the results were expressed as odds ratio (OR) in the association with very negative self-esteem and the respective 95% confidence interval (CI).

RESULTS

A total of 4.283 applications for authorization were submitted, with a return rate of 19.03%, totaling 815 adolescents participating. The minimum sample size was 384 individuals, considering that, for the age group of students, the prevalence of bullying in the city of Araçatuba, State of São Paulo is unknown (50%), with a 5% margin of error and 95%. Regarding all the schools in the municipality, the data collection was performed in two stages: one that took into consideration the schools and the other, the students. Thus, it can be stated that there is an effect of the sampling design of two (referring to 2 collection stages) . The sample size was of at least 768 individuals, which could already be seen as representative but in fact 815 students were examined in all, therefore the sample can be considered representative, besides the bullying estimate in the sample was 48.22%, which is close to the established prevalence and within the margin of error considered.

Table 1 presents the descriptive results of the study containing the following variables: age, sex, skin color, DAI index, Global Negative Self-Evaluation and desire to correct teeth in order to improve appearance. The result descriptive analysis of the bullying questionnaire is shown in Table 2.

Table 3 shows the relationship between low negative self-esteem and very negative self-esteem with the other variables. It was observed that there was no statistically significant association between the variables age range, need for orthodontic treatment, sex of the aggressor, type of bullying suffered and whether the victim had previously been a bully.

The variables which showed significant associations were dichotomized to allow multivariate logistic regression analysis. The frequency with which the bullying occurred was categorized as follows: one episode and more than one episode. Regarding bullying consequences, they were categorized as with and without consequences. Although the following variables: sex, desire to correct the teeth in order to improve the appearance and the bullying episode frequency seen as a risk factor for very negative self-esteem victims, these variables were not significant. The items: Non-white adolescents and bullying with consequences had a significant effect on the occurrence of intimadation (Table 4).

DISCUSSION

The profile of the students surveyed reveals a great deal of female students, with a slight predominance of brown skin color and age showing a balanced distribution among the participants.

In 2010, data from the last census in the municipality, comprising the age group of 5 to 9 years old and 10 to 14 years old, revealed that there is no female predominance whereas in the age group of 5 to 9 years old, the proportion of boys and girls was the same (2.9%) and, in the group of 10-14 years old , there was a small advantage in the percentage of boys when compared to girls (3.7% and 3.4%, respectively)1717 Instituto Brasileiro de geografia e estatística (IBGE). Censo Brasil 2010 [cited 15 Abr 2015]. Available from: http://www.censo2010.ibge.gov.br/sinopse/webservice/frm_piramide.php?codigo=350280

.

The fact that more girls participated in the study may be related to the greater interest of female adolescents in participating in this type of research. This variable had a statistically significant association in the chi-square test and could be considered a risk factor for victims of bullying presenting a very negative self-esteem, although it did not present significance in the logistic regression model.

A possible explanation for this finding is the difference between the factors that influence the self-esteem of girls and boys. Girls are more influenced by issues related to relationships, while boys, by the success achieved in their goals. During adolescence, girls may overestimate the opinion of friends and people they consider important; Thus, criticisms of these relationships over their image are significant66 Bandeira, CM, Hutz CS. Implications of bullying in adolescents' self-esteem. Psicol Esc Educ. 2010;14:131-8. doi: 10.1590/S1413-85572010000100014
https://doi.org/10.1590/S1413-8557201000...
. Thus, it can be concluded that the fact that the girls suffer from bullying, that is, the rejection of the peers, negatively influences the level of their self-esteem

Although it was not the majority of adolescents who reported poor levels of self-esteem, there was a high percentage of those who reported having very negative self-esteem (39.02%). This information is of great importance because the low level of self-esteem may be related to the prevalence of behavioral and emotional disorders, as well as to antisocial behaviors (aggression / violence, criminal activities, suicidal thoughts, smoking, illicit drug use and low school performance)1818 Khajehdaluee M, Zavar A, Alidoust M, Pourandi R. The relation of self-esteem and illegal drug usage in high school students. Iran Red Cres Med J. 2013;15:e7682. doi: 10.5812/ircmj.7682
https://doi.org/10.5812/ircmj.7682...
.

The results showed a high rate of bullying (48.22%). The students were previously instructed to complete the questionnaire about what characterized bullying episodes in order to find out how to differentiate them from games between colleagues. Nevertheless, the prevalence was higher than other similar studies1919 Liang H, Flisher AJ, Lombard CJ. Bullying, violence, and risk behavior in South African school students. Child Abuse Negl. 2007;31:161-71. doi: 10.1016/j.chiabu.2006.08.007

This fact can be justified by the methodological differences employed as well as the cultural differences. In addition, in the present study, there was no temporal limitation, that is, the student was questioned about episodes of bullying in any period prior to the research, thus increasing the chances of detecting more reports. It is essential to emphasize that, even though it is not the objective of the research, situations of violence in the school regions are frequently reported in the local media, which could justify the high percentage of young people involved in bullying episodes.

The majority of adolescents reported having experienced this type of situation more than once. Although it may have happened once, the main characteristic of this type of violence is the fact that the victim is persecuted by his tormentors2121 Aalsma MC, Brown JR. What is bullying? J Adolesc Health. 2008;43:101-2. doi: 10.1016/j.jadohealth.2008.06.001
https://doi.org/10.1016/j.jadohealth.200...
. The results also showed that the most common intimidation was verbal and that the perpetrators, most of the times, were boys. These data are commonly found in other studies on this theme in different regions and countries at all levels of development44 Kowalski RM, Limber SP.

The literature reports that episodes of bullying are strongly related to low levels of self-esteem among adolescents2121 Aalsma MC, Brown JR. What is bullying? J Adolesc Health. 2008;43:101-2. doi: 10.1016/j.jadohealth.2008.06.001

https://doi.org/10.1002/ab.1010...
. Likewise, the present study found a statistically significant association between the victims of bullying and the level of self-esteem. In the logistic regression model, it can be observed that those who suffered bullying as well as non-white adolescents were twice as much prone to present very negative self-esteem. Data released by the National School Health Survey (NSHS), conducted by IBGE in partnership with the Ministry of Health in 2012, also showed a greater chance of black boys being the most victims of bullying2525 Malta DC, Porto DL, Crespo CD, Silva MMA, de Andrade SSC, Mello, FCM, et al. Bullying em escolares brasileiros: análise da Pesquisa Nacional de Saúde do Escolar (PeNSE 2012). Rev Bras Epidemiol. 2014;17(1):92-105..

Brazil is a great miscegenation country, yet certain cultural and socially valued patterns and stereotypes still prevail. Often, these stereotypes are distant from those found in most of the population. Some of the characteristics most valued concerning the appearance are: white skin, straight and blond hair and lean body. It is necessary, therefore, to think about the differences, since the motivation for the practice of bullying comes precisely from the differences, that is, from those who differ from socially valued standards2626 Batista EHM. Bullying and ethnic-racial prejudice. POIÉSIS. 2013;7:302-23.. Racial prejudice is present in all sectors, as well as in the school environment, which can negatively affect the self-esteem of bullying victims.

Bullying consequences in adolescents' lives directly affect very negative self-esteem (odds ratio = 3.343). There are situations in which self-esteem may be so compromised that the victim believes that he or she deserves the violence suffered2424 O'Moore M, Kirkham C.

. Moreover, the consequences of these episodes in childhood can have adulthood repercussions associated with antisocial behavior and loss of opportunities, such as job instability and short-term affective relationships2727 Pearce JB, Thompson AC.

.

Concerning the association between self-esteem and the need for orthodontic treatment, although it was statistically insignificant, it was observed that a large proportion of adolescents evaluated dental care needs related to malocclusion problems. Moreover, it is worth mentioning that, regardless of the need for orthodontic treatment, almost all the participants (91.41%) showed a desire to correct their teeth in order to improve their appearance. This variable can be considered as a risk factor (odds ratio = 1.805) represented as a very negative self-esteem for victims of bullying, showing an expressive o adolescents' concern with their dental appearance.

Bullying can affect the physical and mental health of adolescents, requiring the attention of schools, parents and the community. The present study detected high levels of very negative self-esteem and bullying among schoolchildren, bringing different consequences in adulthood. Thus, it is necessary to identify the risk factors so that adequate preventive actions can be developed.

CONCLUSIONS

It was concluded that there was an association between the variables self-esteem and bullying. Those who reported negative consequences on bullying were three times more likely to have very negative self-esteem, and the chances of non-white adolescents were almost twice as high. There was no statistically significant association between self-esteem and need for orthodontic treatment. Although these findings cannot be generalized to other localities, it is of great importance to understand the reality of different regions, to map this serious public health problem and thus create prevention strategies. In addition, further studies should be conducted using different methodological approaches such as qualitative analysis in order to better understand the feelings of adolescents involved in bullying episodes and longitudinal studies to verify the consequences of these episodes in adult life.
