Profiles of Antisocial Behavior in School-Based and At-Risk Adolescents in Singapore: A Latent Class Analysis.

This study used latent class analysis to examine whether multiple subgroups can be identified based on rule-breaking and aggressive behavior in school-based and at-risk adolescent samples. These groups were tested for differences in behavioral, emotional, personality and interpersonal correlates. Rule breaking and aggressive behavior co-occurred across all classes. School-based adolescents were classified as having minimal, minor or moderate antisocial problems. At-risk adolescents were classified as having mild, medium or severe antisocial problems. Generally, at-risk adolescents had higher levels of antisocial behavior, and greater severity of antisocial behavior was associated with more problems in various domains. Results differed however, for the school-based and at-risk samples with respect to emotional problems, sensation-seeking and peer conformity pressure. There is a need to jointly consider both non-aggressive rule-breaking behavior and aggressive behavior in prevention and intervention work, as it is insufficient to address isolated symptoms and problems in children and adolescents.

Student perceptions of self-efficacy and teacher support for learning in fostering youth competencies: Roles of affective and cognitive engagement.

INTRODUCTION: This exploratory study extends research on student engagement by examining the relationships between its different facets, students' perception of teacher support for learning and self-efficacy, and adaptive youth competencies. Guided by Reschly and Christenson's (2012) student engagement framework, affective and cognitive engagement were posited to mediate the relationships between students' perceived beliefs, adaptive competencies and behavior engagement. METHOD: 3776 Singapore Grade 7 and 8 students completed a self report survey questionnaire. RESULTS: Self-efficacy and teacher support demonstrated different indirect relationships with student competencies and via different engagement pathways. Cognitive engagement mediated the effects of teacher support and self-efficacy on the four student competencies, while affective engagement's mediated effects was only evident on academic buoyancy. CONCLUSION: This study holds important implications for educational and psychological research on student engagement, demonstrating that the construct, though theorized in a western context, has empirical utility and relevance in an East Asian context.

Factor Structure and Invariance of the Reactive and Proactive Aggression Questionnaire in a Large Sample of Young Adolescents in Singapore.

The present study investigated the factor structure, gender invariance, and convergent validity of the scores associated with the Reactive-Proactive Aggression Questionnaire (RPQ) in a Singapore sample of 1027 school-going adolescents. Results demonstrated that the 2-factor reactive-proactive aggression model had a superior fit compared with the 1-factor general aggression model, providing evidence that while reactive and proactive aggression were correlated, they were nevertheless distinct and separable. Current findings also provided empirical support for the invariance of the 2-factor model of the RPQ across gender. Furthermore, convergent validity was examined; while both reactive and proactive aggression were shown to be positively and significantly related to delinquency and narcissism, it was proactive aggression rather than reactive aggression that showed relatively stronger associations with delinquency and narcissism. Collectively, these findings provided evidence that there are meaningful differences between reactive and proactive aggression, and contributed to the cross-cultural generalizability of the RPQ.

The role of delinquency, proactive aggression, psychopathy and behavioral school engagement in reported youth gang membership.

Given the robust positive association between gangs and crime, a better understanding of factors related to reported youth gang membership is critical and especially since youth in gangs are a universal concern. The present study investigated the role of delinquency, proactive aggression, psychopathy and behavioral school engagement in reported youth gang membership using a large sample of 1027 Singapore adolescents. Results from logistic regression showed that delinquency, proactive aggression, and behavioral school engagement were statistically significant risk factors for reported youth gang membership, and that psychopathy was not related to reported gang membership. Implications for prevention and intervention work with respect to youth gang membership were discussed. In particular, strengthening students' engagement with school and meaningful school-related activities and developing supportive teacher-student relationships are particularly important in working with young people with respect to prevention work. Additionally, the present study's theoretical and empirical contributions were also discussed.

The impact of shyness on problematic internet use: the role of loneliness.

In recent years, research indicated that the problematic effects of Internet use must be examined together with individual differences present in its users with which such effects are contingent. This study examined loneliness in adolescents as a mediator of the relationship between shyness and their generalized problematic Internet use (PIU). A total of 1469 adolescents (48.5% male, 51.5% female) from Grade 8 and Grade 9 classes participated in this study. Using the Social Reticence Scale (SRS), the revised UCLA Loneliness scale and the Generalized Problematic Internet Use scale, initial findings indicated significant correlations among the three variables. Results from the study further revealed that loneliness completely mediated the relationship between shyness and generalized problematic Internet use. Implications for intervention work addressing both loneliness and shyness issues facing adolescents who are problematic users of the Internet were discussed.

Cross-cultural invariance of the Academic Expectations Stress Inventory: adolescent samples from Canada and Singapore.

We provide further evidence for the two-factor structure of the 9-item Academic Expectations Stress Inventory (AESI) using confirmatory factor analysis on a sample of 289 Canadian adolescents and 310 Singaporean adolescents. Examination of measurement invariance tests the assumption that the model underlying a set of scores is directly comparable across groups. This study also examined the cross-cultural validity of the AESI using multigroup confirmatory factor analysis across both the Canadian and Singaporean adolescent samples. The results suggested cross-cultural invariance of form, factor loadings, and factor variances and covariances of the AESI across both samples. Evidence of AESI's convergent and discriminant validity was also reported. Findings from t-tests revealed that Singaporean adolescents reported a significantly higher level of academic stress arising from self expectations, other expectations, and overall academic stress, compared to Canadian adolescents. Also, a larger cross-cultural effect was associated with academic stress arising from other expectations compared with academic stress arising from self expectations.

Functions of Aggression and Delinquency: The Moderating Role of Parent Criminality and Friends' Gang Membership.

This study examined the relationships between two functions of aggression (i.e., reactive and proactive) and delinquency, including the moderating effects of parent criminality and friends' gang membership, in a sample of 1,027 Singaporean adolescents from Grade 7 to Grade 9, with age ranging from 12 to 19 years ( M = 14.10, SD = 1.15). Findings suggested that both reactive aggression and proactive aggression significantly and positively predicted delinquency (after controlling for proactive aggression and reactive aggression, respectively), with proactive aggression being a stronger predictor. Friends' gang membership was found to moderate the relationship between reactive aggression and delinquency, and proactive aggression and delinquency, with stronger moderator effects for the latter. Those who were aggressive proactively and who had friends in a gang appear to be impacted most negatively with respect to delinquency. Parent criminality did not moderate these relationships. These findings highlight the need to effectively address the issues of child and adolescent aggression. Also, developing positive peer relations early is crucial for delinquency prevention.

Validation of the Adolescent Concerns Measure (ACM): evidence from exploratory and confirmatory factor analysis.

This article reports the development and initial validation of scores obtained from the Adolescent Concerns Measure (ACM), a scale which assesses concerns of Asian adolescent students. In Study 1, findings from exploratory factor analysis using 619 adolescents suggested a 24-item scale with four correlated factors--Family Concerns (9 items), Peer Concerns (5 items), Personal Concerns (6 items), and School Concerns (4 items). Initial estimates of convergent validity for ACM scores were also reported. The four-factor structure of ACM scores derived from Study 1 was confirmed via confirmatory factor analysis in Study 2 using a two-fold cross-validation procedure with a separate sample of 811 adolescents. Support was found for both the multidimensional and hierarchical models of adolescent concerns using the ACM. Internal consistency and test-retest reliability estimates were adequate for research purposes. ACM scores show promise as a reliable and potentially valid measure of Asian adolescents' concerns.

Gender differences in adolescent concerns and emotional well-being: perceptions of Singaporean adolescent students.

Although much has been written about adolescent adjustment and coping in Western countries, relatively little is known about similar issues in Asia. The authors examined the emotional adjustment of young adolescents in Singapore. They report adolescent concerns and how they influence adaptive functioning and emotional well-being. Data were obtained from three self-report measures: the Adolescent Concerns Measure (R. P Ang, W. H. Chong, V. S. Huan, & L. S. Yeo, in press), selected scales of the Behavioral Assessment System for Children Personality Self-Report (C. R. Reynolds & R. W. Kamphaus, 1998), and the Emotional Distress Scale of the Reynolds Adolescent Adjustment Screening Inventory (W. M. Reynolds, 2001). Emotional well-being emerged as a dominant concern for Singaporean youths with significant gender differences. Girls reported a more positive attitude toward school, better friendship skills, and stronger relationships with parents than did boys. However, girls registered significantly greater worries about self and emotional distress compared to boys. The authors discuss implications for teachers and mental health professionals.

The influence of dispositional optimism and gender on adolescents' perception of academic stress.

This study investigated the role of optimism together with gender, on students' perception of academic stress. Four hundred and thirty secondary school students from Singapore participated in this study and data were collected using two self-report measures: the Life Orientation Test and the Academic Expectation Stress Inventory. Results revealed a significant negative relationship between optimism and academic stress in students. Gender was not a significant predictor of academic stress and no two-way interactions were found between optimism and gender of the participants. Possible explanations for the results were suggested and implications of the findings were discussed.

Re-Examining of Moffitt's Theory of Delinquency through Agent Based Modeling.

Moffitt's theory of delinquency suggests that at-risk youths can be divided into two groups, the adolescence- limited group and the life-course-persistent group, predetermined at a young age, and social interactions between these two groups become important during the adolescent years. We built an agent-based model based on the microscopic interactions Moffitt described: (i) a maturity gap that dictates (ii) the cost and reward of antisocial behavior, and (iii) agents imitating the antisocial behaviors of others more successful than themselves, to find indeed the two groups emerging in our simulations. Moreover, through an intervention simulation where we moved selected agents from one social network to another, we also found that the social network plays an important role in shaping the life course outcome.

Understanding the relationship between proactive and reactive aggression, and cyberbullying across United States and Singapore adolescent samples.

This study examined cyberbullying among adolescents across United States and Singapore samples. Specifically, the purpose of the investigation was to study the differential associations between proactive and reactive aggression, and cyberbullying across two cultures. A total of 425 adolescents from the United States (M age = 13 years) and a total of 332 adolescents from Singapore (M age = 14.2 years) participated in the study. Results of the moderator analyses suggested that nationality was not a moderator of the relationship between proactive aggression and cyberbullying, and between reactive aggression and cyberbullying. As expected, findings showed proactive aggression to be positively associated with cyberbullying, after controlling for reactive aggression, across both samples. Likewise, as hypothesized, reactive aggression and cyberbullying was not found to be significant after controlling for proactive aggression across both samples. Implications of these findings were discussed: (a) Proactive aggression is a possible risk factor for both bullying and cyberbullying; (b) proactive and reactive aggression could be argued to be distinct as they have different correlates-only proactive aggression contributed to cyberbullying after controlling for reactive aggression; (c) this research extends previous work and contributes toward cross-cultural work using similar and comparable measures across different samples; and (d) prevention and intervention programs targeted at proactive aggressive adolescents could adopt a two-pronged approach by changing mind sets, and by understanding and adopting a set of rules for Internet etiquette.

The influence of father criminality on juvenile recidivism: testing for delinquent behaviors as a mediator.

This study investigates the relationships between father criminality, prior delinquency, and recidivism using data from 382 incarcerated juveniles assessed in Singapore's Juvenile Court in 2005. The juveniles are aged 13 to 16 years, with a mean of 14.55 years (SD = 0.93). Using Baron and Kenny's framework, this study tests the prediction that the prior delinquent behaviors of the juvenile mediate the relationship between father criminality and recidivism in a four-step process. When the juvenile's prior delinquent behaviors are included in the model, the previous significant relation between father criminality and recidivism disappears. Implications of findings in terms of applied and practical intervention and prevention work for youths in schools and those in incarceration are discussed.

Factorial structure and invariance of the academic expectations stress inventory across Hispanic and Chinese adolescent samples.

Using confirmatory factor analysis, the current study provided further evidence for the two-factor structure of the Academic Expectations Stress Inventory [AESI; Ang RP, Huan VS (2006) Educ Psych Meas 66:522-539] using a sample of 191 US Hispanic adolescents and a sample of 211 Singapore Chinese adolescents. This study also examined the cross-cultural validity of the AESI using multigroup confirmatory factor analysis to investigate the invariance of the factor structure of the AESI across both samples. Results from multigroup confirmatory factor analysis suggested that while partial invariance was observed across the samples, the consistency of fit indices indicating either no change or a minimal loss of fit between the unconstrained basic model and the partially constrained models, provided support that partial invariance was acceptable. Analyses of covariance results indicated that perceived overall academic stress and academic stress arising from self-expectations were significantly higher among Singapore Chinese adolescents compared with US Hispanic adolescents.

Relationship between academic stress and suicidal ideation: testing for depression as a mediator using multiple regression.

Relations among academic stress, depression, and suicidal ideation were examined in 1,108 Asian adolescents 12-18 years old from a secondary school in Singapore. Using Baron and Kenny's [J Pers Soc Psychol 51:1173-1192, 1986] framework, this study tested the prediction that adolescent depression mediated the relationship between academic stress and suicidal ideation in a four-step process. The previously significant relationship between academic stress and suicidal ideation was significantly reduced in magnitude when depression was included in the model providing evidence in this sample that adolescent depression was a partial mediator. The applied and practical implications for intervention and prevention work in schools are discussed. The present investigation also served as a demonstration to illustrate how multiple regression analyses can be used as one possible method for testing mediation effects within child psychology and psychiatry.
