Teacher characteristics, social classroom relationships, and children's social, emotional, and behavioral classroom adjustment in special education.

The goal of this study was to explore relations between teacher characteristics (i.e., competence and wellbeing); social classroom relationships (i.e., teacher-child and peer interactions); and children's social, emotional, and behavioral classroom adjustment. These relations were explored at both the individual and classroom levels among 414 children with emotional and behavioral disorders placed in special education. Two models were specified. In the first model, children's classroom adjustment was regressed on social relationships and teacher characteristics. In the second model, reversed links were examined by regressing teacher characteristics on social relationships and children's adjustment. Results of model 1 showed that, at the individual level, better social and emotional adjustment of children was predicted by higher levels of teacher-child closeness and better behavioral adjustment was predicted by both positive teacher-child and peer interactions. At the classroom level, positive social relationships were predicted by higher levels of teacher competence, which in turn were associated with lower classroom levels of social problems. Higher levels of teacher wellbeing were directly associated with classroom adaptive and maladaptive child outcomes. Results of model 2 showed that, at the individual and classroom levels, only the emotional and behavioral problems of children predicted social classroom relationships. At the classroom level, teacher competence was best predicted by positive teacher-child relationships and teacher wellbeing was best predicted by classroom levels of prosocial behavior. We discuss the importance of positive teacher-child and peer interactions for children placed in special education and suggest ways of improving classroom processes by targeting teacher competence.

Developmental links between disobedient behavior and social classroom relationships in boys with psychiatric disorders in special education.

In mainstream education, positive relationships with teachers and peers have been found to positively influence children's behavioral development. However, high levels of classroom behavior problems may hinder the formation of such positive relationships. Therefore, findings from mainstream education cannot be generalized to special education. The present study investigated the developmental links between disobedience and positive as well as negative relationships with teachers and peers among boys in restrictive special educational settings. At three assessment waves across one school year, teacher-reports of teacher-child closeness and conflict, and peer-reports of peer acceptance, rejection and disobedience were collected among 340 boys (mean age = 10.1 years, SD = 1.58, range = 5-13) with psychiatric disorders receiving special education. Autoregressive cross-lagged models were fitted to explore the nature of these developmental links. The impact of boys' age was examined using multiple group analyses. Findings supported the importance of teacher-child conflict, but not closeness, and positive and negative peer relationships for the development of boys' disobedience, with a stronger effect of negative than positive relationships. However, teacher-child and peer relationships were not longitudinally related and the effect of boys' age was minimal. This study extends prior research by suggesting that, despite differences in educational setting and severity of behavior problems between children in mainstream and special education, reducing negative classroom interactional patterns is most important in preventing the development of problematic classroom behavior in boys with severe social-emotional and behavioral difficulties.

Twenty-year trends in emotional and behavioral problems in Dutch children in a changing society.

OBJECTIVE: Research into changes in the prevalence of children's psychiatric diagnoses has indicated an increase in recent decades. However, methodological problems may have influenced results. This study compared children's emotional and behavioral problem levels across three population samples from different time points across 20 years, assessed with identical methodologies. METHOD: We compared Child Behavior Checklists and Teacher's Report Forms across three population samples of 6- to 16-year olds, assessed in 1983, 1993, and 2003. RESULTS: We found evidence for small increases in the mean population levels of parent-reported problems, and in the percentages of children with serious problems. These changes concerned mostly internalizing problems. Teacher reports showed less changes. Decreases in scores were found on several areas of competence. Changes were the strongest between 1993 and 2003. CONCLUSION: We found evidence for small increases in Dutch children's problems. Further developments must be monitored, as this trend may continue and have serious societal consequences.

Naturally occurring xanthine urolithiasis in a domestic shorthair cat.

A five-year-old neutered male domestic shorthair cat was presented after three episodes of urethral obstruction and anuria requiring relief urethral catheterisation. A double contrast cystogram revealed the presence of multiple small cystoliths which were radiolucent on plain radiographs. A perineal urethrostomy and a cystotomy were performed to relieve the urethral obstruction and to remove the cystoliths. Quantitative analysis revealed the cystoliths to be composed of 100 per cent xanthine. Clinical history suggested the xanthinuria to be naturally occurring. Unfortunately, the cat was killed in a road traffic accident two months after the surgical procedure, preventing further long-term assessment.
