For the Z-Generation, the Internet has become a very important experimentation laboratory for the discovery and validation of their identity. Despite the importance of the process of building the self in the adolescent, there are hardly any validated instruments that measure the self online. The aim of this research was to design and validate the…

This study investigated the structure and concurrent validity of the Beliefs About Fighting Scale (BAFS). Participants were 2,118 students from three urban middle schools who completed measures of their beliefs, frequency of physical aggression, victimization, and nonviolent intentions. Ratings of students' frequency of physical aggression,…

We present validity evidence for the Expectancy-Value-Cost (EVC) Scale of student motivation. Using a brief, 10-item scale, we measured middle school students' expectancy, value, and cost for their math and science classes in the Fall and Winter of the same academic year. Confirmatory factor analyses supported the three-factor structure of the EVC…

Valid measurement of how students' experiences in secondary school classrooms lead to gains in learning requires a developmental approach to conceptualizing classroom processes. This article presents a potentially useful theoretical model, the Teaching Through Interactions framework, which posits teacher-student interactions as a central driver…

The purpose of this study was to examine the differentiation and correlates of shyness and unsociability during early adolescence in urban and rural China. Participants were 93 urban and 229 rural Chinese sixth- to eighth-graders. Students rated their shyness, unsociability, fear of negative evaluation, self-efficacy for peer interactions, and…

This study applies multi-level analysis to student reports of effective teacher-student interactions in 50 upper elementary school classrooms (N = 594 fourth- and fifth-grade students). Observational studies suggest that teacher-student interactions fall into three domains: Emotional Support, Classroom Organization, and Instructional Support.…

Most research exploring the interplay between context and adolescent separation and detachment has focused on the family; in contrast, this investigation directs its attention outside of the family to peers. Utilizing a latent variable approach for modeling interactions and incorporating reports of behavioral adjustment from 14-year-old…

While both outsiders and defenders have antibullying attitudes, only defenders have the reputation to defend victims. However, outsiders--despite their reputation of avoiding involvement in bullying--do receive some defender nominations and thus defend victims at least occasionally. This study investigated the relationship between these behavioral…

This study examined the reliability and validity of the Classroom Assessment Scoring System-Secondary (CLASS-S) in Finnish classrooms. Trained observers coded classroom interactions based on video recordings of 46 Grade 6 classrooms (450 cycles). Concurrent associations were investigated with respect to teacher self-ratings (e.g., efficacy beliefs…

The current study investigated whether invulnerability manifests with adaptive and maladaptive outcomes during early adolescence. We sampled 248 (53% female; 63% Caucasian; [[X-bar]][subscript age] = 13.2 years) early adolescents on the Adolescent Invulnerability Scale (AIS), and measures of drug use, delinquency, depressive symptoms, and mastery…

This study investigated individual differences in sixth-grade students (N = 181; 47% girls, ethnically diverse) use of friends as a coping resource when dealing with a social stressor with another peer at school. Confirmatory factor analysis supported the hypothesized three factor structure of coping with friends: mastery, avoidance, and…

This study investigates the factor structure, reliability, and validity of the Inventory of Teacher-Student Relationships (IT-SR), a measure that was developed by adapting the widely used Inventory of Parent and Peer Attachments (Armsden & Greenberg, 1987) for use in the context of teacher-student relationships. The instrument was field tested…

This study investigated cultural identity and peer influence on tobacco, alcohol, and cannabis use in a culturally diverse sample of Northern Australian adolescents. Middle school students (n = 274) completed the Multigroup Ethnic Identity Measure (MEIM) and measures of their own and perceived friends' substance use. Higher scores on the full…

The authors describe the development and initial psychometric properties of the Friendship Motivation Scale for Children, a new scale designed to assess four dimensions of self-determination (i.e., intrinsic motivation, identified regulation, external regulation, and amotivation) in preadolescents and early adolescents' desire for friendships. The…

Applied confirmatory factor analysis in a test of alternative factor models and measurement invariance across gender groups, using data from the Early Adolescent Temperament Questionnaire focusing on shyness, high-intensity pleasure, activity level, attention, irritability, and fear. Found that factor models based on composite indicators showed…
