ObjectiveTo develop a child victimization survey among a diverse group of child protection experts and examine the performance of the instrument through a set of international pilot studies.MethodsThe initial draft of the instrument was developed after input from scientists and practitioners representing 40 countries. Volunteers from the larger group of scientists participating in the Delphi review of the ICAST P and R reviewed the ICAST C by email in 2 rounds resulting in a final instrument. The ICAST C was then translated and back translated into six languages and field tested in four countries using a convenience sample of 571 children 12–17 years of age selected from schools and classrooms to which the investigators had easy access.ResultsThe final ICAST C Home has 38 items and the ICAST C Institution has 44 items. These items serve as screeners and positive endorsements are followed by queries for frequency and perpetrator. Half of respondents were boys (49%). Endorsement for various forms of victimization ranged from 0 to 51%. Many children report violence exposure (51%), physical victimization (55%), psychological victimization (66%), sexual victimization (18%), and neglect in their homes (37%) in the last year. High rates of physical victimization (57%), psychological victimization (59%), and sexual victimization (22%) were also reported in schools in the last year. Internal consistency was moderate to high (alpha between .685 and .855) and missing data low (less than 1.5% for all but one item).ConclusionsIn pilot testing, the ICAST C identifies high rates of child victimization in all domains. Rates of missing data are low, and internal consistency is moderate to high. Pilot testing demonstrated the feasibility of using child self-report as one strategy to assess child victimization.Practice implicationsThe ICAST C is a multi-national, multi-lingual, consensus-based survey instrument. It is available in six languages for international research to estimate child victimization. Assessing the prevalence of child victimization is critical in understanding the scope of the problem, setting national and local priorities, and garnering support for program and policy development aimed at child protection. 相似文献

This study examined how inferences about epistemic competence and generalized labeling errors influence children’s selective word learning. Three- to 4-year-olds (N = 128) learned words from informants who asked questions about objects, mentioning either correct or incorrect labels. Such questions do not convey stark differences in informants’ epistemic competence. Inaccurate labels, however, generate error signals that can lead to weaker encoding of novel information. Preschoolers retained novel labels from both informants but were slower to respond in the Inaccurate Labeler condition. When the test procedure was not sensitive to the strength of information encoding, children performed above chance in both conditions and their response times did not differ. These results suggest that epistemic-level inferences and error generalizations influence preschoolers’ selective word learning concurrently. 相似文献

Recent studies have shown that there are systematic differences among total and free prostate-specificantigen (PSA) immunoassays. In this study we analyzedintermethod differences in total PSA (tPSA) and free PSA(fPSA) measurement using ARCHITECT i2000SR (Abbott Diagnostics) and COBAS E601 (Roche Diagnostics). A number of 160 blood samples were tested for tPSA and 50 samples for fPSA (selecting only sampleswith tPSA: 4.1–10.0 μg/L). Passing–Bablok regression analysis was used to compare the two analytical methods fortPSA, fPSA and percentage of fPSA (%fPSA). A strong correlation was noticed between ARCHITECT i2000SR and COBAS E601 for tPSA, fPSA and %fPSA (r between 0.94 and 0.99). Concentrations of tPSA and fPSA measured by COBAS E601 were higher thanthose measured by ARCHITECT i2000SR with a bias of 0.8 μg/L for tPSA and 0.14 μg/L for fPSA. Analyzing therelative difference between methods for fPSA and %fPSA, COBAS E601 exceed a 10% relative difference limit. Our study confirms that there are differences in measured concentrations of tPSA and fPSA byvarious commercial methods. Because clinical judgment on subsequent diagnostic procedures, such as prostatebiopsy, is based on tPSA and fPSA results, tests harmonization should be a priority. 相似文献

Parents' contribution to sex education is increasingly receiving research attention. This growing interest stems from recognition of the influence that parental attitudes may have both on young people's sexual attitudes and behaviour, and on school-based sex education. Studies regarding parental attitudes towards sexuality are, however, still rare. The two main objectives of this study were to explore parental views about sexuality and to understand parental attitudes towards sex education. Four focus group discussions were conducted with parents from high schools in Cuenca, Ecuador. Data were analysed using thematic analysis. The study revealed that parents held a restricted view about sex education, grounded in traditional religious ideas about sexuality, which led parents to understand it as a morally and physically dangerous activity. Although parents expressed a willingness to make good quality sex education available to their children, they reported having insufficient personal resources to fulfil that objective. The results of this study provide important information about the need to develop and adapt sex education to each specific cultural context, thereby confirming the importance of knowing about the cultural traditions and religious beliefs that may form obstacles to effective sex education for young people in Ecuador. 相似文献

A longitudinal study analyzed (a) which lower- and higher-level semantic components uniquely predicted listening text comprehension and (b) the nature of the relation (i.e., direct and indirect) between the predictors and listening text comprehension in preschoolers. One-hundred and fifty-two children participated in the present study (68 females; mean age = 4;10 years/months and 5;5 years/months at Time 1 and Time 2, respectively). Participants were administered measures to evaluate listening text comprehension (Time 1 and Time 2) and (a) expressive and receptive word knowledge (lower-level semantic components), and (b) inferential skills and the ability to use context (higher-level semantic components) (Time 1). Verbal short-term and working memory were also included as control variables. Data were analyzed using path analysis models. Results showed that both types of semantic components (a) accounted for unique variance in listening text comprehension at Time 2, with lower-level semantic components explaining a larger proportion of variance than higher-level semantic components; (b) were related to later listening text comprehension through direct and indirect relations. Memory resources did not significantly contribute to listening text comprehension. The results are discussed in light of their theoretical relevance and educational/practical implications. 相似文献

This study investigated the relation between theory of mind (ToM) and metamemory knowledge using a training methodology. Sixty‐two 4‐ to 5‐year‐old children were recruited and randomly assigned to one of two training conditions: A first‐order false belief (ToM) and a control condition. Intervention and control groups were equivalent at pretest for age, parents' education, verbal ability, inhibition, and ToM. Results showed that after the intervention children in the ToM group improved in their first‐order false belief understanding significantly more than children in the control condition. Crucially, the positive effect of the ToM intervention was stable over 2 months and generalized to more complex ToM tasks and metamemory. 相似文献

There is growing evidence that children develop orthographic knowledge from the very beginning of literacy acquisition. This study investigated the development of German‐speaking children's orthographic knowledge with a nonword choice task. One nonword in each pair contained a frequent consonant doublet (zommul) and the other nonword contained an infrequent doublet (zobbul). Children (N = 54) performed at chance level in kindergarten but chose nonwords with frequent doublets significantly more often than expected by chance in first and second grade. Correlations between children's orthographic knowledge and their reading and spelling skills were not found. The results indicate that knowledge of frequent double consonants is evident in German‐speaking children from first grade onwards, but it is not related to their reading and spelling performance. This finding is consistent with the view that children in transparent orthographies rely less on frequent letter patterns during reading and spelling compared to children in deep orthographies. 相似文献

The loss of co-workers due to retirement has a profound impact on the people who are left to carry on with the work of the unit. The process of recovery from the loss of experienced and long-serving support staff members is analogous to the stages of grief that a person experiences after the death of a loved one. This article describes how the Serials Services unit at the University of Victoria Libraries is coping with the consequences of the retirement of its two most experienced library assistants and discusses the steps taken in order to continue to provide quality service to users. 相似文献
