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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.
