Gender-specific responses to multifaceted factors associated with disordered eating among adolescents of 7th to 9th grade

Background The prevalence of disordered eating is increasing among adolescents in Asia. The prevalence and predictors of disordered eating in boys have often gone unrecognized. This study examined gender-specific responses to multifaceted factors associated with disordered eating, including personal, behavioral, family, and school-related characteristics. Methods After excluding responses with incomplete information, a sample of 729 adolescents (48.97% boys) between the ages of 13 and 16 were surveyed through convenience sampling from 37 classrooms in three junior high schools in New Taipei City of Taiwan were analyzed. The Eating Attitudes Test-26 questionnaire was used to identify disordered eating. Results No difference in the prevalence of disordered eating between the genders was found. Adolescent girls exhibit a preoccupation with fatness and a desire to be thinner, whereas boys are more likely to engage in extreme dieting behaviors such as vomiting, keeping the stomach empty, and avoiding sweets. Girls engaging in disordered eating reported relatively high levels of interpersonal stress involving family member weight-teasing, low peer acceptance, and high peer pressure to control weight. High intensity of regular exercise was found in girls with disordered eating. The perception of body weight is a more critical factor of engaging in disordered eating for boys than girls. Adolescents with immigrant parents were associated with disordered eating among both genders. Conclusions Changing gender-specific weight-related norms in schools and families is essential to reduce the prevalence of disordered eating, particularly among girls. Future studies using representative samples to confirm this study’s findings are warranted.

An unsupervised method for social network spammer detection based on user information interests

Online Social Networks (OSNs) are a popular platform for communication and collaboration. Spammers are highly active in OSNs. Uncovering spammers has become one of the most challenging problems in OSNs. Classification-based supervised approaches are the most commonly used method for detecting spammers. Classification-based systems suffer from limitations of “data labelling”, “spam drift”, “imbalanced datasets” and “data fabrication”. These limitations effect the accuracy of a classifier’s detection. An unsupervised approach does not require labelled datasets. We aim to address the limitation of data labelling and spam drifting through an unsupervised approach.We present a pure unsupervised approach for spammer detection based on the peer acceptance of a user in a social network to distinguish spammers from genuine users. The peer acceptance of a user to another user is calculated based on common shared interests over multiple shared topics between the two users. The main contribution of this paper is the introduction of a pure unsupervised spammer detection approach based on users’ peer acceptance. Our approach does not require labelled training datasets. While it does not better the accuracy of supervised classification-based approaches, our approach has become a successful alternative for traditional classifiers for spam detection by achieving an accuracy of 96.9%.

Peer Relationships and Depressive Symptoms Among Adolescents: Results From the German BELLA Study

Background: Poor mental health affects adolescent development and is associated with health and social outcomes in later life. The current study uses cross-sectional data to explore the understudied aspects of peer relationships as a predictor of depressive symptom severity of adolescents in Germany.Method: Data from the German BELLA study were analyzed. We focused on the most recent measurement point of the BELLA study and analyzed data of 446 adolescents (aged 14–17 years). Peer relationship was measured using four items from the internationally established Patient-Reported Outcome Measurement Information System (PROMIS). Depressive symptoms were assessed via seven items of the German version of the Centre for Epidemiological Studies Short Depression Scale (CES-D). Hierarchical linear regression models were computed to explore the association between depressive symptoms and peer relationships. Hierarchical linear regression models served to determine the added predictive effects of each aspect of peer relationships.Result: The regression model showed that 22% of the variance of the severity of depressive symptoms could be explained by the quality of adolescents’ peer relationships (F(1,444) = 125.65, p < 0.001). Peer acceptance has the most substantial unique contribution to peer relationship as a predictor of depressive symptom severity (Change in R2 = 0.05; Change in F = 27.01, p < 0.001). The gender-specific analysis shows different trends for boys and girls.Conclusion: The quality of peer relationships is a significant predictor of adolescents’ depressive symptoms severity. Improved peer acceptance, dependability, and ease of making new friends are significantly associated with reduced depression symptoms for Germany’s adolescent population.

Effects of Bystander's Emotional Empathy and Social Problem-Solving Skills on Defending Behaviors Against Bullying in Elementary School: Mediated Through Peer Acceptance

Objectives: Many children are exposed to their peers being bullied, which negatively impacts individuals and the society as a whole. We investigated the effects of elementary school children’s emotional empathy and social problem-solving skills on their defending behaviors. We evaluated the direct and indirect effects of these personal characteristics, mediated through their perceived peer acceptance among classmates. Gender differences were also tested.Methods: The study participants were 386 fourth- and fifth-graders (M = 10.4 yrs.) from six elementary schools in the metropolitan Seoul area of South Korea. Children’s perceived social acceptance, emotional empathy, and problem-solving skills were measured using self-reported questionnaires. Defending behavior was measured using peer nomination. To analyze the data, descriptive statistics and structural equation modeling were conducted using SPSS 21.0 and MPLUS 6.12.Results: Bystanders‘ emotional empathy and social problem-solving skills had significant effects on defending behaviors. Social problem-solving skills directly affected defending behaviors of boys and girls. Girls’ peer acceptance mediated both emotional empathy and social problem-solving skills for defending behaviors, while no mediation effect was found in boys.Conclusion: For children, feeling accepted by classmates is important for defending bullied peers. For girls, peer acceptance magnifies their socio-emotional and socio-cognitive skills, empowering them to defend the bullied peers. However, for boys, having competent socio-cognitive skills alone is sufficient. Based on this study’s findings, it is recommended that interventions are needed to enhance bystanders’ emotional empathy and social problem-solving skills, and thereby, empowering them to be competent defenders against school bullying.

Children’s autistic traits and peer relationships: do non-verbal IQ and externalizing problems play a role?

Background Children with autism have difficulties in understanding relationships, yet little is known about the levels of autistic traits with regard to peer relationships. This study examined the association between autistic traits and peer relationships. Additionally, we examined whether the expected negative association is more pronounced in children with a lower non-verbal IQ and in those who exhibit more externalizing problems. Method Data were collected in a large prospective birth cohort of the Generation R Study (Rotterdam, the Netherlands) for which nearly 10,000 pregnant mothers were recruited between 2002 and 2006. Follow up data collection is still currently ongoing. Information on peer relationships was collected with PEERS application, an interactive computerized task (M = 7.8 years). Autistic traits were assessed among general primary school children by using the Social Responsiveness Scale (M = 6.1 years). Information was available for 1580 children. Result Higher levels of autistic traits predicted lower peer acceptance and higher peer rejection. The interaction of autistic traits with externalizing problems (but not with non-verbal IQ or sex) was significant: only among children with low externalizing problems, a higher level of autistic traits predicted less peer acceptance and more peer rejection. Among children exhibiting high externalizing problems, a poor peer acceptance and high level of rejection is seen independently of the level of autistic traits. Conclusion We conclude that autistic traits—including traits that do not classify as severe enough for a clinical diagnosis—as well as externalizing problems negatively impact young children’s peer relationships. This suggests that children with these traits may benefit from careful monitoring and interventions focused at improving peer relationships.

Predicting suicidal thoughts and behavior among adolescents using the risk and protective factor framework: A large-scale machine learning approach

Introduction Addressing the problem of suicidal thoughts and behavior (STB) in adolescents requires understanding the associated risk factors. While previous research has identified individual risk and protective factors associated with many adolescent social morbidities, modern machine learning approaches can help identify risk and protective factors that interact (group) to provide predictive power for STB. This study aims to develop a prediction algorithm for STB among adolescents using the risk and protective factor framework and social determinants of health. Methods The sample population consisted of more than 179,000 high school students living in Utah and participating in the Communities That Care (CTC) Youth Survey from 2011-2017. The dataset includes responses to 300+ questions from the CTC and 8000+ demographic factors from the American Census Survey for a total of 1.2 billion values. Machine learning techniques were employed to extract the survey questions that were best able to predict answers indicative of STB, using recent work in interpretable machine learning. Results Analysis showed strong predictive power, with the ability to predict individuals with STB with 91% accuracy. After extracting the top ten questions that most affected model predictions, questions fell into four main categories: familial life, drug consumption, demographics, and peer acceptance at school. Conclusions Modern machine learning approaches provide new methods for understanding the interaction between root causes and outcomes, such as STB. The model developed in this study showed significant improvement in predictive accuracy compared to previous research. Results indicate that certain risk and protective factors, such as adolescents being threatened or harassed through digital media or bullied at school, and exposure or involvement in serious arguments and yelling at home are the leading predictors of STB and can help narrow and reaffirm priority prevention programming and areas of focused policymaking.

PEER ACCEPTANCE, AND PERCEPTION OF ACCEPTANCE OF STUDENTS WITH VISUAL IMPAIRMENTS IN AN INCLUSIVE SETTING IN GHANA / ACCEPTATION PAR LES PAIRS, ET PERCEPTION DE L'ACCEPTATION DES ÉLÈVES DÉFICIENTS VISUELS DANS UN ENVIRONNEMENT INCLUSIF AU GHANA

<p>This study explored the level of peer acceptance of students with visual impairments and their perception of acceptance by their sighted peers in an inclusive setting in Ghana using the case study design. Twenty students with visual impairments and two resource teachers were sampled based on census sampling for the study. Interview data were coded and analysed using the thematic approach. The study indicated that students with visual impairments were accepted by their sighted peers, more especially, based on their social skills and academic prowess. The study further revealed that students with visual impairments have a positive perception about their social participation in the school. Although the students were fairly satisfied about their participation, they expressed their frustration on how some teachers’ instructions excluded them in class. It was recommended among others in the study that teachers in inclusive schools should organise more counselling or sensitisation programmes for all students to educate them on issues of disabilities and how to ensure friendly relationships between students with and those without disabilities. This would promote better acceptance of the disabled by those without disabilities. Resource persons who are special educators are also encouraged to periodically sensitize teachers on classroom instructions.</p><p> </p><p>Cette étude a exploré le niveau d'acceptation par les pairs des étudiants ayant de déficiences visuelles et leur perception de l'acceptation par leurs pairs voyants dans un environnement inclusif au Ghana, en utilisant la conception d'étude de cas. Vingt étudiants ayant de déficiences visuelles et deux enseignants-ressources ont été sélectionnés sur la base d'un échantillonnage de recensement pour l'étude. Les données issues de l’entretien ont été codées et analysées à l'aide de l'approche thématique. L'étude indique que les étudiants malvoyants sont acceptés par leurs pairs voyants, plus particulièrement en raison de leurs compétences sociales et de leurs prouesses scolaires. L'étude a également révélé que les étudiants ayant de déficiences visuelles ont une perception positive par rapport à leur participation sociale à l'école. Bien que les étudiants soient assez satisfaits de leur participation, ils ont exprimé leur frustration sur la façon dont certains enseignants les excluent au cours de l’enseignement en classe. L'étude recommande, entre autres, que les enseignants des écoles inclusives organisent davantage de programmes de conseil ou de sensibilisation pour tous les élèves afin de les éduquer sur les questions de handicap et sur la manière d'assurer des relations amicales entre les élèves handicapés et non handicapés. Cela favoriserait l'acceptation des personnes handicapées par les personnes non handicapées. Les personnes ressources qui sont des éducateurs spécialisés sont également encouragées à sensibiliser périodiquement les enseignants sur l’enseignement en classe.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0893/a.php" alt="Hit counter" /></p>

Long-Term Effects of Acceptance and Rejection by Parents and Peers on Educational Attainment: A Study from Pre-Adolescence to Early Adulthood

Acceptance and rejection by parents and peers play an important role in pre-adolescents’ educational outcomes. Prior research focused on either parents or peers, did not encompass effects into adulthood, or considered either acceptance or rejection. This study investigated the relation between parental and peer acceptance and rejection, and their interplay, in pre-adolescence and educational attainment in early adulthood. A sample of 2229 pre-adolescents (Mage T1 = 11.11, SD = 0.56; 50.7% girls) was followed to early adulthood (Mage T5 = 22.29, SD = 0.65). Ordinal logistic regression showed that pre-adolescents’ perceived parental acceptance was positively related to educational attainment in early adulthood, whereas peer rejection was negatively related, even when WISC score and socioeconomic status were considered. No interaction effects were found, revealing no “dual-hit effect” of being rejected by parents and peers, no “dual-miss effect” of being accepted by parents and peers, and no effects of acceptance in one context (i.e., parents or peers) buffering the negative effect of rejection in the other context. The findings underscore unique and long-term links of parental acceptance and peer rejection with early adults’ educational attainment, underlining the importance of not only peers but also parents in adolescence. These insights can be used in promoting long-term educational outcomes through relationships with parents and peers.

Measurement Burst Designs to Improve Precision in Peer Research

Measurement burst designs, in which assessments of a set of constructs are made at two or more times in quick succession (e.g., within days), can be used as a novel method to improve the stability of basic measures typically used in longitudinal peer research. In this Element, we hypothesized that the stabilities for adolescent-reported peer acceptance, anxiety, and self-concept would be stronger when using the measurement burst approach versus the single time observation. Participants included youth between 10 and 13 years old who completed (a) sociometric assessments of acceptance, and measures of (b) social and test anxiety, and (c) self-concept across three times with two assessments made at each burst. Findings broadly showed that the stabilities were significantly stronger with the measurement burst when compared to the single time assessment, supporting our main hypothesis. We discuss the utility of the measurement burst in a broader context and considerations for researchers.
