ABSTRACT
Developmental cascade models linking childhood physical and relational aggression with symptoms of depression and attention-deficit/hyperactivity disorder (ADHD; assessed at ages 10, 11, 12, 13, and 14) to borderline personality disorder (BPD) features (assessed at age 14) were examined in a community sample of 484 youth. Results indicated that, when controlling for within-time covariance and across-time stability in the examination of cross-lagged relations among study variables, BPD features at age 14 were predicted by childhood relational aggression and symptoms of depression for boys, and physical and relational aggression, symptoms of depression, and symptoms of ADHD for girls. Moreover, for boys BPD features were predicted from age 10 ADHD through age 12 depression, whereas for girls the pathway to elevated BPD features at age 14 was from depression at age 10 through physical aggression symptoms at age 12. Controlling for earlier associations among variables, we found that for girls the strongest predictor of BPD features at age 14 was physical aggression, whereas for boys all the risk indicators shared a similar predictive impact. This study adds to the growing literature showing that physical and relational aggression ought to be considered when examining early precursors of BPD features.

OBJECTIVE: To examine trends in mechanism and outcome of major traumatic injury in adults since the implementation of the New South Wales trauma monitoring program, and to identify factors associated with mortality. DESIGN AND SETTING: Retrospective review of NSW Trauma Registry data from 1 January 2003 to 31 December 2007, including patient demographics, year of injury, and level of trauma centre where definitive treatment was provided. PARTICIPANTS: 9769 people aged ≥ 15 years hospitalised for trauma, with an injury severity score (ISS) > 15. MAIN OUTCOME MEASURES: The NSW Trauma Registry outcome measures included were overall hospital length of stay, length of stay in an intensive care unit and in ospital mortality. RESULTS: There was a decreasing trend in severe trauma presentations in the age group 16-34 years, and an increasing trend in presentations of older people, particularly those aged ≥ 75 years. Road trauma and falls were consistently the commonest injury mechanisms. There were 1328 inhospital deaths (13.6%). Year of injury, level of trauma centre, ISS, head/neck injury and age were all independent predictors of mortality. The odds of mortality was significantly higher among patients receiving definitive care at regional trauma centres compared with Level I centres (odds ratio, 1.34; 95% CI, 1.10-1.63). CONCLUSIONS: Deaths from major trauma in NSW trauma centres have declined since 2003, and definitive care at a Level 1 trauma centre was associated with a survival benefit. More comprehensive trauma data collection with timely analysis will improve injury surveillance and better inform health policy in NSW.

The aim of the present study was to compare recollections of sexual, physical, verbal, social, and cyber peer victimization experienced in high school in terms of depressed affect, self-esteem, and loneliness experienced in university. In all, 247 university students (70 males and 177 females; M = 20.62, SD = 2.54) completed online measures assessing retrospective accounts of their experiences of different forms of peer victimization during high school (i.e., sexual, physical, verbal, social, and cyber) and their current psychosocial adjustment (i.e., self-esteem, depressed affect, and loneliness). Three separate hierarchical multiple regressions were conducted to determine whether different indices of negative psychosocial adjustment are more strongly predicted by experiencing sexual or nonsexual forms of peer victimization. Although many university students recalled experiencing sexual peer victimization in high school at least once at an even higher percentage than verbal and social forms of peer victimization, the results of the present study suggest that social peer victimization in high school predicts higher levels of depressed affect and loneliness in university students than sexual peer victimization experienced in high school. Surprisingly, the young adults reporting higher levels of cyber peer victimization in high school were less lonely in university. Although the hypothesized relationships between each form of peer victimization and specific indices of psychosocial functioning were not consistently supported, these findings suggest that the form of peer victimization matters and may be differentially associated with well-being in emerging adulthood. It is important that future research explores how individual characteristics may further predict varied experiences of peer victimization and the long-term impact of those experiences.

Recent evidence suggests that people who score low on measures of sociability may be at risk for certain types of psychopathology, including mood and anxiety disorders. In an attempt to extend these findings to other forms of psychopathology, we examined levels of neuroticism and extraversion in relation to eating problems in a non-clinical sample of undergraduate women. The Eysenck Personality Questionnaire (EPQ), Eating Disorders Inventory (EDI), and the Eating Attitudes Test (EAT-26) were completed by 196 first-year undergraduate females. We found that high neuroticism was related to high scores on both of the EDI subscales (Bulimia and Drive for Thinness) as well as high scores on the EAT-26 measure, replicating previous work. In addition, neuroticism served as a moderator such that lower extraversion (i.e., introversion) was related to greater disordered eating, but only for those women who scored high on neuroticism. Thus, a combination of neuroticism and introversion may be a risk-factor for symptoms of eating disorders in a non-clinical sample of university women.

The relative impact of school transition versus development on peer victimization and bullying perpetration were examined in a natural experiment involving 698 students where half transitioned into middle school from Grade 5 to Grade 6 and the other half remained in their elementary school over the same period. Results indicated that, on average, peer victimization decreased over the transition period while bullying perpetration remained stable for the whole sample. Multilevel modeling was used to investigate the effects of school transition and sex on changes in victimization and perpetration. Results indicated that the effect of transition status on changes in peer victimization was moderated by sex. Middle school transition status predicted decreases in peer victimization for girls, but not for boys, who transitioned. However, school transition status and participants' sex (and their interaction) did not predict changes in perpetration over time. Our findings indicate that changes in student involvement with peer victimization are better understood as a contextual rather than a typical developmental process, whereas bullying perpetration may be better understood as developmental.

Recent research on developmental dyslexia has suggested a phonological core deficit hypothesis (e.g., Manis, Seidenberg, Doi, McBride-Chang, & Peterson, 1996; Stanovich, Siegel, & Gottardo, 1997) whereby pure cases of developmental phonological dyslexia (dysfunctional phonetic decoding processing but normal sight vocabulary processing) can exist, but pure cases of developmental surface dyslexia (dysfunctional sight vocabulary processing but normal phonetic decoding processing) should not. By applying Jacoby's (1991) and Lindsay and Jacoby's (1994) process dissociation procedure to the reading of regular and exception words, we present a method that serves to estimate readers' reliance on sight vocabulary and phonetic decoding during real word recognition. These reliance estimates are then used in Castles and Coltheart's (1993) regression-based approach to identify normal readers and developmental dyslexics. This new method: (1) allows one to explore normal reading acquisition and both the delay and deviance accounts of developmental dyslexia, (2) provides an alternative to matching dyslexics to both chronological-age and reading-age control groups, and (3) uses only real words. We present evidence that pure cases of developmental surface dyslexia can be obtained with both Castles and Coltheart's measure as well as our own, and that developmental surface dyslexia is not simply a delayed reading deficit. The theoretical importance and utility of estimates of reliance on sight vocabulary and phonetic decoding is discussed.

The study of peer victimization has drawn together researchers, parents, teachers, and health professionals around the world in an effort to make change. Research attention has focused on the question of whether peer victimization in childhood and adolescence leads to lasting and serious negative ramifications in the lives of young people. We consider the wealth of information documenting the troubling adjustment that follows peer victimization within childhood and adolescence. Findings from prospective studies tracking children and adolescents into young adulthood are presented and synthesized. Using the construct of "multifinality" as our framework, we explore why it might be that early peer victimization does not have the same impact on all young people by considering factors that place individuals at greater risk or appear to protect them from more lasting harm. In addition to a need for carefully planned prospective studies, the field would benefit from the use of qualitative studies aimed at elucidating possible causal, concurrent, and resultant mechanisms involved with victimization.

BACKGROUND: Legg-Perthes disease is associated with ischemia of the capital femoral epiphysis in children. Thrombophilia has been implicated as a potential cause of the condition, and screening of patients with Legg-Perthes disease for thrombophilia has been recommended. We analyzed the value of screening for inherited thrombophilia in patients with Legg-Perthes disease by examining the association between Legg-Perthes disease and abnormalities in the thrombotic pathway. METHODS: A random series of consecutive patients with Legg-Perthes disease were prospectively enrolled in this study. Assays for the detection of factor-V Leiden mutation and the plasma concentrations of protein C, protein S, antithrombin III, and lipoprotein (a) were performed on plasma samples from children with Legg-Perthes disease, and the results were compared with those for pooled plasma from normal controls. Plasma concentrations below the 95% midrange of the control values were classified as protein deficiencies. The estimated population frequency of each coagulation abnormality was compared with the proportion of the study group with the corresponding abnormality. RESULTS: The proportion of abnormalities observed in the study group did not differ from the estimated population frequency for protein C, protein S, antithrombin III, or factor-V Leiden mutation. A lipoprotein (a) level of >30 mg/dL (>1.07 micro mol/L) was found in 16% of the study group. CONCLUSIONS: Our data do not suggest that thrombotic diatheses due to deficiency of protein C, protein S, or antithrombin III or due to factor-V Leiden mutation are major causes of Legg-Perthes disease. The elevated levels of lipoprotein (a) in children with Legg-Perthes disease suggest that they may be at risk for atherosclerosis as adults.

School-level school climate was examined in relation to self-reported peer victimization and teacher-rated academic achievement (grade point average; GPA). Participants included a sample of 1,023 fifth-grade children nested within 50 schools. Associations between peer victimization, school climate, and GPA were examined using multilevel modeling, with school climate as a contextual variable. Boys and girls reported no differences in victimization by their peers, although boys had lower GPAs than girls. Peer victimization was related to lower GPA and to a poorer perception of school climate (individual-level), which was also associated with lower GPA. Results of multilevel analyses revealed that peer victimization was again negatively associated with GPA, and that lower school-level climate was associated with lower GPA. Although no moderating effects of school-level school climate or sex were observed, the relation between peer victimization and GPA remained significant after taking into account (a) school-level climate scores, (b) individual variability in school-climate scores, and (c) several covariates--ethnicity, absenteeism, household income, parental education, percentage of minority students, type of school, and bullying perpetration. These findings underscore the importance of a positive school climate for academic success and viewing school climate as a fundamental collective school outcome. Results also speak to the importance of viewing peer victimization as being harmfully linked to students' academic performance.

Developmental cascade models linking childhood peer victimization, internalizing and externalizing problems, and academic functioning were examined in a sample of 695 children assessed in Grade 3 (academic only) and Grades 5, 6, 7, and 8. Results revealed several complex patterns of associations in which poorer functioning in one domain influenced poorer outcomes in other areas. For example, a symptom driven pathway was consistently found with internalizing problems predicting future peer victimization. Support for an academic incompetence model was also found-- lower GPA in Grade 5, 6, and 7 was associated with more externalizing issues in the following year, and poor writing performance in Grade 3 predicted lower grades in Grade 5, which in turn predicted more externalizing problems in Grade 6. Results highlight the need to examine bidirectional influences and multifarious transactions that exist between peer victimization, mental health, and academic functioning over time.

Injuries represent a significant health burden in Australia. In New South Wales (NSW), no routine follow-up of post-injury health outcomes is conducted. This article describes the development of a protocol and the conduct of a pilot study to collect information on trauma outcomes at 3 months post-injury at two trauma centres. A modified Victorian model of trauma outcomes monitoring was adopted, with potential participants required to 'opt in' to the collection. Fifty-three percent of individuals contacted consented to opt in, with 75% of these completing an interview. The data items collected were able to provide an indicator of the impact of trauma on individuals. This study has highlighted that there are important methodological issues to be addressed in terms of recruitment in establishing long-term trauma outcomes data collections that are representative of the trauma population. Ultimately, information from a long-term trauma outcomes collection could be linked to data collections to conduct research across the injury continuum.

Trustworthiness was examined in children and early adolescents from two countries. In Study 1,505 children in the fifth and sixth school years in the United Kingdom (mean age = 9 years 7 months) were tested across an 8-month period. In Study 2,350 sixth- through eighth-grade Canadian children and early adolescents (mean age = 12 years 11 months) were tested across a 1-year period. Participants completed measures assessing trustworthiness (ratings of promise and secret keeping by peer group and also by best friend in Study 1), assertiveness (Study 1), prosocial behavior (Study 2), social relationships (friendships and peer preference), and psychological adjustment (self-esteem, depressive symptoms, and loneliness). Peer-reported trustworthiness was positively associated with, and predicted changes across time in, the number of friendships. The observed relations were found to be statistically independent of peer preference and peer-reported assertiveness or prosocial behavior. Trustworthiness was found to be positively associated with peer preference (Study 1 and Study 2) and psychological adjustment (Study 1).
