This study examined whether characteristics of a positive school climate were associated with lower student risk behavior in a sample of 3,687 high school students who completed the School Climate Bullying Survey and questions about risk behavior from the Youth Risk Behavior Surveillance Survey (YRBS). Confirmatory factor analyses established fit for 20 items with three hypothesized school climate scales measuring (1) prevalence of bullying and teasing; (2) aggressive attitudes; and (3) student willingness to seek help. Structural equation modeling established the relationship of these measures with student reports of risk behavior. Multigroup analyses identified differential effects across gender and race. A positive school climate could be an important protective factor in preventing student risk behavior.

In 2 studies, we examined the use of validity screening items in adolescent survey data. In each study, adolescent respondents were asked whether they were telling the truth and paying attention in answering survey questions. In Study 1 (N = 7,801), the prevalence rates of student risk behaviors were significantly lower after inappropriate (invalid) responders were screened out of the sample. In addition, confirmatory and multigroup factor analyses demonstrated significant differences between the factor structures of school climate scales with valid versus invalid responders. In Study 2, student perceptions of school climate were correlated with teacher perceptions in 291 schools. A bootstrap resampling procedure compared the correlations obtained with valid versus invalid responding students in each school and found that valid responders had more positive views of school conditions and produced higher correlations with teacher perceptions. These findings support the value of validity screening items in improving the quality of adolescent survey data.

To determine whether larger high schools have more student victimization than smaller schools, this study examined a statewide sample of approximately 7,431 ninth-grade students and 2,353 teachers in 290 Virginia high schools participating in the Virginia High School Safety Study. School size was distinguished from the proportion of students receiving free or reduced-price meals, percentage of minority students, ethnic diversity (heterogeneity), and urbanicity. In larger schools, teachers and students reported that they perceived more bullying and teasing taking place, but student self-reports of being a victim of bullying were not associated with school size. Additionally, school discipline records showed that although the total number of incidents was higher, the rate of bullying offenses was lower in larger schools. Similar results were found for measures of student threats and physical assaults. These findings raise the possibility that the link between larger schools and higher student victimization is an illusion based on perceived frequency rather than rates of victimization.

Three young children diagnosed with autism did not reliably locate objects in the environment on the basis of an adult's gaze shifts. A training program designed to teach gaze following used the activation of remote controlled mechanical toys as both prompts and consequences. Over several training sessions, toy activation was progressively delayed following the adult's gaze-shift cues. All of the children eventually came to anticipate the toy activation and locate the target object on the basis of the adult's gaze-shift cue alone. Discrimination of another person's gaze direction is discussed in relation to joint attention deficits in children with autism.
