Moderators of the Link Between Social Preference and Persistent Peer Victimization for Elementary School Children.

OBJECTIVE: Current antibullying programs can reduce overall rates of victimization but appear to overlook processes that give rise to persistent peer victimization. Needed are studies that delineate the interplay between social contextual and individual difference variables that contribute to persistent peer victimization. We examined the extent to which two individual-difference variables - internalizing symptoms (IS) and anxiety sensitivity (AS) - moderated the link between children's average social preference score across the school year and their status as persistent victims. METHOD: Participants included 659 4th-grade students (Mage = 9.31 years, SD = 0.50, 51.8% girls; 42.3% Latinx, 28.9% non-Hispanic White, 10.2% Pacific Islander, 7.7% Bi/Multiracial, 1.9% Black, 1.7% Asian, 1.7% Native American, and 3.4% unreported) from 10 public elementary schools in the U.S. RESULTS: As expected, higher social preference scores predicted a decreased likelihood of being persistently victimized. Conversely, IS and AS were positively linked to persistent victim status. AS significantly moderated the link between social preference and persistent victim status such that for children with high AS, compared to those with AS scores at or below the mean, the negative association between social preference and persistent victim status was attenuated. CONCLUSIONS: Findings provide evidence that children who experience high levels of IS and AS are at risk for being persistently victimized by peers and that high AS could signal increased risk for persistent victimization even when children are generally liked by peers. We discuss the implications of these findings for efforts to develop focused interventions for chronically bullied children.

Informal mentoring support as a potential moderator of the relation between adolescent dating violence victimization and substance use.

Research links adolescent dating violence (ADV) victimization to negative developmental outcomes, including involvement in substance use. Informal mentoring is associated with several positive outcomes, including reduced risk of substance use. Addressed in this study is whether support from an informal mentor can function to protect victims of ADV from involvement in substance use. Participants were 152 adolescents (grades 9-12). Findings revealed a significant association between ADV victimization and adolescents' involvement in substance use, as well as some evidence that support from an informal mentor moderates that link. When informal mentor support was low or at the mean, ADV victimization was significantly linked to adolescents' involvement in substance use; when informal mentor support was high, ADV victimization was unrelated to substance use involvement. Discussed are research and practice implications of the potential protective role of informal mentors for victims of ADV.

Measurement of aggressive behavior in early childhood: A critical analysis using five informants.

Measurement of aggressive behavior in early childhood is unique given that relational aggression is just developing, physical aggression is still prevalent, and both forms of aggression are relatively overt or direct. The current study had three aims. The first aim was to examine the internal reliability, validity, and correspondence of five different assessments of aggressive behavior in early childhood: parent report, teacher report, observer report, child report, and naturalistic school-based observations. The second aim was to test a one- and two-factor model of early childhood aggression using confirmatory factor analysis. The final aim of the study was to investigate gender differences among different reports of aggression. Observations, teacher report, and observer (research assistant) report were collected in the children's school, and parent report and child report were collected in a lab session at one time point (N = 300; 56% male; Mage = 44.86 months, SD = 5.55). Observations were collected using a focal child sampling with continuous recording approach, and previously validated measures were used for the remaining four informants. Results demonstrated that all measures were reliable with the exception of child report of relational aggression, and there was small to strong correspondence among the various informants. In addition, a two-factor structure of aggression provided the best fit to the data, providing evidence for divergence among relational and physical aggression. Finally, there were robust gender differences in physical aggression, but gender differences in relational aggression varied by method. The implications of different types of measurement are discussed.

The effect of caste and reproductive state on the chemistry of the cephalic labial glands secretion of Bombus terrestris.

The cephalic labial glands are well developed in many bee species. In bumble bee males, they cover most of the head volume, and their secretion is used in marking reproductive territories and attracting virgin queens. In females, however, they are poorly studied. Here, we present chemical analyses of their secretion in queens and workers of Bombus terrestris under various social conditions. The secretion revealed a context-dependent composition with sterile females possessing large amounts of fatty acid dodecyl esters, ranging from dodecyl hexanoate to dodecyl oleate, compared to small amounts in fertile females. Significant reduction in the dodecyl esters also was found in queens at the competition phase, where worker reproduction, aggression, and gyne differentiation occur. The exclusive production of esters by sterile individuals also is typical of Dufour's gland secretion in this species, albeit in this case these are octyl rather than dodecyl esters, and the differences between sterile and fertile individuals are qualitative rather than quantitative. We propose that the labial gland esters provide yet another signal of reproductive inactivity. In virgin queens, it may signal that egg laying is deferred to the next season, while in workers it reinforces the message "I am sterile and out of the reproductive competition". Whether the reduction in dodecyl esters in fertile queens as a function of colony social development is involved in regulating gyne production and the onset of the competition phase is yet to be deciphered.

Awareness and education of patients receiving bisphosphonates.

BACKGROUND: Bisphosphonates are used to fight osteoporosis and for treating malignancies. In 2003, the first case reports appeared that described bisphosphonate-induced osteonecrosis of the jaw (BONJ). The aim of this study was to assess patient awareness of the adverse effects of bisphosphonates in order to improve cooperation among doctors and between doctors and patients. METHODS: Patients with symptoms of osteoporosis, prostate cancer, or breast cancer were surveyed to determine their knowledge of bisphosphonates. The questionnaire comprised 12 questions that covered sociographic data, kind of medication, level of information, and side effects experienced. Out of 142 patients contacted, 55 participated in the study. RESULTS: 62% of patients received most of their knowledge about the prescribed drug from the package insert. Despite knowledge that the patient was under treatment with bisphosphonates, 80% of dental treatments were continued without modifications. Only 32% of patients that received intravenous bisphosphonate treatment were aware of the possible risks of developing BONJ. CONCLUSION: The level of information is poor concerning the side effects of bisphosphonates, particularly the risk of BONJ. Clinicians should aim to sensitize the relevant people about the risks before treatment.
