Prevalence of school bullying and its relationship with attention deficit-hyperactivity disorder and conduct disorder: a cross-sectional study

Background

School bullying is the most widespread form of violence among adolescents. It has been identified as a critical problem for students and has evolved into a public health issue and global crisis. The study aims to assess the prevalence of school bullying among primary school students and its relationship with attention deficit hyperactive disorder (ADHD) and conduct disorders. Among the 280 primary school students those aged 10–12 years were recruited. All participants were assessed by parent interview, the Arabic version of the bullying behavior scale for children and adolescents and the Arabic version of the Conners’ Teacher Rating Scale-28.

Results

We found that the prevalence rate of bullying behavior was 12.5% among students. In bullying students’ group, males were higher percentage (15.8%) than females (9%). Also, they had the highest mean scores regarding verbal bullying and social bullying, followed by psychological and physical bullying. Regarding Conners’, the higher mean scores of conduct problem, passive-inattentive, and hyperactivity index were associated with bullying students in compared to students without bullying.

Conclusions

The prevalence of school bullying among primary school students was 12.5%. Also, there was significant association between bullying students and having attention deficit hyperactive disorder (ADHD) and/or conduct disorder.

A review of psychosocial factors linked to adolescent substance use

PURPOSE

Informed by ecological theories and models of influence, this review discusses various psychosocial risk and protective factors that contribute to adolescent substance use behavior. Given typical patterns of substance use initiation during this developmental period, an emphasis is placed on alcohol, cigarette, and marijuana use.

FINDINGS

Consistent with bioecological theories, peers and parents tend to have the strongest effect on adolescent substance use behavior. Influences can be both direct, such as offers and availability to use substances, as well as indirect influences, such as the perception of substance use approval. Schools and neighborhoods also contribute to adolescent substance use behavior, but this effect is often less direct. Moreover, the effect of neighborhoods on adolescent behavior reflects both structural components (e.g., neighborhood racial composition, teacher-student ratios) in addition to social process (e.g., neighborhood social cohesion, school connectedness). A review of parallel studies conducted with animals is also provided.

SUMMARY

Adolescent substance use behavior does not occur in a vacuum. Investigations must encompass the relevant social ecologies that affect adolescent behavior, including family, peer, school, and neighborhood contexts to provide a more complete understanding of substance use etiology.

Future Directions in Peer Relations Research

Peer relationships among youth have been examined as predictors of mental health outcomes for at least fifty years, revealing dozens of discrete peer constructs that each are associated with adjustment in childhood, adolescence, and later in adulthood. Future research may benefit by examining a range of new outcomes and psychological processes that have been discussed recently in related literatures. This paper reviews recent research on interpersonal determinants of physical health outcomes, and opportunities for greater examination of 1) peer influence processes toward health risk behaviors; 2) neural correlates of peer adversity; 3) adverse peer experiences that may affect physiological markers of stress response; and 4) immune system markers of peer adversity. Additional future directions include the study of differences in the forms and functions of peer interactions within the digital age.

Brain responses and approach bias to social alcohol cues and their association with drinking in a social setting in young adult males

Alcohol is mainly consumed in social settings, in which people often adapt their drinking behaviour to that of others, also called imitation of drinking. Yet, it remains unclear what drives this drinking in a social setting. In this study, we expected to see stronger brain and behavioural responses to social compared to non-social alcohol cues, and these responses to be associated with drinking in a social setting. The sample consisted of 153 beer-drinking males, aged 18-25 years. Brain responses to social alcohol cues were measured during an alcohol cue-exposure task performed in an fMRI scanner. Behavioural responses to social alcohol cues were measured using a stimulus-response compatibility task, providing an index of approach bias towards these cues. Drinking in a social setting was measured in a laboratory mimicking a bar environment. Specific brain responses to social alcohol cues were observed in the bilateral superior temporal sulcus and the left inferior parietal lobe. There was no approach bias towards social alcohol cues specifically; however, we did find an approach bias towards alcohol (versus soda) cues in general. Brain responses and approach bias towards social alcohol cues were unrelated and not associated with actual drinking. Thus, we found no support for a relation between drinking in a social setting on the one hand, and brain cue-reactivity or behavioural approach biases to social alcohol cues on the other hand. This suggests that, in contrast to our hypothesis, drinking in a social setting may not be driven by brain or behavioural responses to social alcohol cues.

Prevalence and correlates of bullying and victimization among school students in rural Egypt

OBJECTIVES

Knowledge on risk factors of bullying and victimization among school students is crucial for the implementation of preventive measures. This study was conducted to determine the prevalence and correlates of school bullying and victimization and their association with behavioral disorders among preparatory and secondary school students in rural Egypt.

STUDY DESIGN

Cross-sectional METHODS: A total of 476 students from two mixed public schools in rural Egypt (one preparatory and one secondary) were enrolled. A pretested self-administered questionnaire was used to collect sociodemographic characteristics and correlates of bullying and victimization including personal and social, family, school, and community factors. Frequency of bullying and victimization was measured using the short version aggression and victimization scale. The Strengths and Difficulties Questionnaire (SDQ) was used for screening behavioral problems.

RESULTS

Prevalence of bullying behavior was high (77.8%) among the studied group, of those 9.5% were unique bullies, 10.5% were unique victims, and 57.8% were bully-victims. On multivariate logistic regression analysis, failure in previous scholastic years (OR = 11.1, 95% CI 1.1-101.4, P = 0.033), witnessing family members using weapons (OR = 6.1, 95% CI 1.1-34.0, P = 0.038), male gender (OR = 2.3, 95% CI 1.1-5.0, P = 0.027), and mothers' education (university or higher) (OR = 0.1, 95% CI 0.02-0.7, P = 0.017) remained the significant predictors for bullying. However, only having a drug addict friend (OR 2.5, 95% CI 1.1-5.4, P = 0.025) was the significant predictor for victimization. The independent predictors for being bully-victims in order of importance were exposure to physical violence in the street (OR = 5.1, 95% CI 1.2-22.7, P = 0.031), male gender (OR = 3.2, 95% CI 1.8-5.6, P < 0.001), witnessing fights (OR = 3.1, 95% CI 1.7-5.7, P < 0.001) and insulting words (OR = 2.5, 95% CI 1.3-4.7, P = 0.007) among family members, exposure to insulting words in the street (OR = 2.1, 95% CI 1.2-3.7, P = 0.010), watching violent movies (OR = 2.0, 95% CI 1.2-3.4, P = 0.008), and younger age (OR = 0.7, 95% CI 0.6-0.8, P < 0.001). The self-reported SDQ revealed that the conduct problems scale scored significantly higher among bully-victims (2.8 ± 1.7 vs. 2.3 ± 1.6, P = 0.004).

CONCLUSIONS

Prevalence of bullying behavior was high among rural adolescent school students. Establishment of a bullying prevention committee at school including all school personnel for addressing different factors associated with bullying behavior is recommended. Further follow-up and psychiatric assessment of students for predicting those prone to behavioral abnormalities are also recommended.

Understanding adolescent binge drinking in Spain: how school information campaigns moderate the role of perceived parental and peer consumption

Despite its potentially harmful effects, adolescent binge drinking is becoming increasingly common worldwide. To enable the design of more effective school information campaigns, the underlying factors of heavy alcohol use must be carefully analysed. This study investigated how individual, social and contextual factors relate to adolescent binge drinking. It also explored whether adolescents' exposure to information campaigns at school moderates the relationships between perceived parental and peer alcohol consumption and adolescent binge drinking. We used data from a Spanish nationwide representative sample of 47 803 students aged 14-18 years, of whom 25 576 had engaged in binge drinking behaviours. Data were collected every 2 years between 2006 and 2012. For the multilevel estimation in 2012, the sample comprised 10 577 students. Whilst perceived problems associated with binge drinking and perceived difficulty in accessing alcohol were associated with low levels of binge drinking, adolescents' perceptions of parental and peer consumption were associated, to a greater degree, with high levels of binge drinking. School information campaigns moderated the relationship between parental consumption and adolescent binge drinking but not the relationship between peer consumption and adolescent binge drinking. We conclude by highlighting implications for policymakers and offering possible directions for future research.

Homophily in delinquent behavior: The rise and fall of friend similarity across adolescence

This study examined age-related changes in friend similarity on delinquency to determine whether deviant behavior homophily peaks during mid-adolescence. A community sample of 1,663 male and 1,826 female Swedish youth from Grade 5 ( M = 11.21 years) to Grade 10 ( M = 16.25 years) provided self-reports of delinquency. Friendships were identified from nominations. Intraclass correlations revealed age group differences in friend delinquency similarity, independent of normative age-related changes in deviant behavior. Cross-sectional results indicated that similarity was greatest in the seventh grade ( M = 13.21 years). Longitudinal results from a subsample of participants revealed an increase in friend similarity from ages 11 to 13 (Grades 5 to 7) and a decline in friend similarity from ages 14 to 16 (Grades 8 to 10). The findings demonstrate that similarity between friends in delinquent behavior peaks in mid-adolescence, independent of normative age-related changes in participation in deviant acts.

The Role of Self-Control and Early Adolescents' Friendships in the Development of Externalizing Behavior: The SNARE Study

This social network study investigated the moderating role of self-control in the association between friendship and the development of externalizing behavior: Antisocial behavior, alcohol use, tobacco use. Previous studies have shown inconsistent findings, and did not control for possible friendship network or selection effects. We tested two complementary hypotheses: (1) That early-adolescents with low self-control develop externalizing behavior regardless of their friends' behavior, or (2) as a result of being influenced by their friends' externalizing behavior to a greater extent. Hypotheses were investigated using data from the SNARE (Social Network Analysis of Risk behavior in Early adolescence) study (N = 1144, 50 % boys, M age 12.7, SD = 0.47). We controlled for selection effects and the network structure, using a data-analysis package called SIENA. The main findings indicate that personal low self-control and friends' externalizing behaviors both predict early adolescents' increasing externalizing behaviors, but they do so independently. Therefore, interventions should focus on all early adolescents' with a lower self-control, rather than focus on those adolescents with a lower self-control who also have friends who engage in externalizing behavior.

Interaction matters: quantifying conduct problem × depressive symptoms interaction and its association with adolescent alcohol, cigarette, and marijuana use in a national sample

Substance use is a major contributor to morbidity and mortality among American adolescents. Conduct problems and depressive symptoms have each been found to be associated with adolescent substance use. Although they are highly comorbid, the role of the interaction of conduct problems and depressive symptoms in substance use is not clear. In national samples of 8th-, 10th-, and 12th-grade students from the Monitoring the Future study, latent moderated structural equation modeling was used to estimate the association of conduct problems, depressive symptoms, and their interaction to the use of alcohol (including binge drinking), cigarettes, and marijuana. Moderation by age and sex was tested. The interaction of conduct problems with depressive symptoms was a strong predictor of substance use, particularly among younger adolescents. With few exceptions, adolescents with high levels of both conduct problems and depressive symptoms used substances most frequently. Conduct problems were a strong positive predictor of substance use, and depressive symptoms were a weak positive predictor. Whereas conduct problems are often thought to be a primary predictor of substance use, this study revealed that depressive symptoms potentiate the relation of conduct problems to substance use. Therefore, substance use prevention efforts should target both depressive symptoms and conduct problems.

Moderators of the association between peer and target adolescent substance use

Associating with substance using peers is generally considered as one of the most important predictors of adolescent substance use. However, peer association does not affect all adolescents in the same way. To better understand when and under what conditions peer association is most linked with adolescent substance use (SU), this review focuses on the factors that may operate as moderators of this association. The review highlighted several potential moderators reflecting adolescents' individual characteristics (e.g., pubertal status, genes and personality), peer and parental factors (e.g., nature of relationships and parental monitoring), and contextual factors (e.g., peer, school and neighborhood context). As peer association is a broad concept, important methodological aspects were also addressed in order to illustrate how they can potentially bias interpretation. Taking these into account, we suggest that, while the effects of some moderators are clear (e.g., parental monitoring and sensation seeking), others are less straightforward (e.g., neighborhood) and need to be further examined. This review also provides recommendations for addressing different methodological concerns in the study of moderators, including: the use of longitudinal and experimental studies and the use of mediated moderation. These will be key for developing theory and effective prevention.

Best friends and alcohol use in adolescence: the role of the dopamine D4 receptor gene

The influence of friends and peers is theoretically one of the most consistent and important factors explaining adolescent alcohol use. However, not all adolescents are equally likely to be influenced by their friends' drinking behaviors. Genetic factors may underlie these inter-individual differences in susceptibility to the drinking behavior of friends. Because the long allele (≥ 7 repeats) of the dopamine D4 receptor (DRD4) gene has been associated with susceptibility to alcohol and alcohol-related cues, we tested whether associations between best friend's and adolescent's alcohol use differed for DRD4 genotypes. A Dutch nationwide sample of 308 adolescents (age 13 at baseline) participated in a prospective, community-based study with five annual waves. A cross-lagged path analysis was carried out in Mplus to examine bi-directional relations between friends' and adolescents' weekly alcohol use (number of drinks). A multi-group approach was applied to test for moderation effects of a 48-base pair variable number of tandem repeats polymorphism in exon 3 of the DRD4 gene. Additionally, with latent growth curve models, it was examined whether the interaction between friends' drinking and DRD4 genotype predicted the development of adolescents' alcohol use. Results showed that both cross-sectionally and longitudinally higher levels of friends' alcohol use resulted in higher levels of adolescents' alcohol consumption over time (and vice versa). No significant moderation of DRD4 genotype was found: Associations between adolescents' and friends' drinking did not differ for adolescent carriers of the DRD4 long allele, when compared with adolescents without the DRD4 long allele. Because this is the first study to examine DRD4 × friends' drinking effects prospectively, replication is essential. Future longitudinal studies, possibly with observational or diary designs, are needed to increase our understanding of the interplay between genetic and environmental risk factors for adolescent alcohol use.
