This study reports on aggressive outcomes from a cluster randomized trial of the Promoting Alternative Thinking Strategies (PATHS) curriculum. Fourteen elementary schools were randomly assigned to intervention or control condition and third grade students were followed through the fifth grade. Teacher and self-reports of student aggression, conduct problems, delinquency, acting out problems, and social information processing (SIP) variables were collected. Linear change for each of the SIP variables was noted with control students demonstrating increased normative beliefs about aggression, increased aggressive social problem solving, increased hostile attribution bias, and increased aggressive interpersonal negotiation strategies over time while PATHS students remained relatively stable. Teachers reported significant curvilinear change in student aggression, conduct problems, and acting out behavior problems; all favoring PATHS students.  相似文献

Underage drinking continues to be an important public health problem and a challenge to the substance abuse prevention field. Community-based interventions designed to more rigorously control underage access to alcohol through retailer education and greater enforcement of underage drinking laws have been advocated as potentially effective strategies to help address this problem, but studies designed to evaluate such interventions are sparse. To address this issue we conducted a randomized trial involving 36 communities to test the combined effectiveness of five interrelated intervention components designed to reduce underage access to alcohol. The intervention was found to be effective in reducing the likelihood that retail clerks would sell alcohol to underage-looking buyers, but did not reduce underage drinking or the perceived availability of alcohol among high school students. Post hoc analyses, however, revealed significant associations between the level of underage drinking law enforcement in the intervention communities and reductions in both 30-day use of alcohol and binge drinking. The findings highlight the difficulty in reducing youth drinking even when efforts to curtail retail access are successful. Study findings also suggest that high intensity implementation of underage drinking law enforcement can reduce underage drinking. Any such effects of enhanced enforcement on underage drinking appear to be more directly attributable to an increase in perceived likelihood of enforcement and the resultant perceived inconveniences and/or sanctions to potential drinkers, than to a reduction in access to alcohol per se.  相似文献

In this study, the authors aim to clarify whether the subject–object asymmetry in relative clause comprehension is due to the use of parsing strategies (Active Filler Theory) or to a greater memory load generated by object sentences. Two experiments investigate how individual differences in working memory span may influence the reading times of relative sentences in Italian, a language characterized by a flexible structure. The results of Experiment 1 indicate that object extraction is more complex than subject extraction when sentences have a canonical structure. Furthermore, low-span participants have particular difficulties with object relative sentence comprehension. The results of Experiment 2 show that subject-relative clauses with uncanonical structures are more complex to understand than object-relative clauses, and low-span participants have more difficulties than high-span participants in elaborating both subject and object relative clauses. These data seem to be coherent with the Active Filler Theory.  相似文献

The current study tests a model that depicts the relationships among coping strategies (active, distraction, avoidance, and support seeking) and anxiety symptoms. SEM is used to test if the relationship between these variables is mediated by coping efficacy. A large sample of Canadian children (N = 506) aged 8 to 11 years (boys = 249, girls = 245, unknown gender = 12) participated in the study. Results showed that coping efficacy is a partial mediator of the relations between active coping strategies and anxiety symptoms, however support was not found for it to be an effective mediator for other coping strategies. This study contributes to the understanding of childhood anxiety by highlighting the importance of the relationship between anxiety and the methods children use to cope with stress and how perceptions of their coping abilities influence this relationship.  相似文献

This paper presents confirmatory factor models with fixed factor loadings that enable the identification of deviations from the expected processing strategy. The instructions usually define the expected processing strategy to a considerable degree. Simplification is a deviation from instructions that is likely to occur in complex cognitive measures. Since simplification impairs the validity of the measure, its identification is important. Models representing simplicity and instruction-based processing strategies were considered in investigating the data of 345 participants obtained by a working memory measure in order to find out whether and how the use of these strategies influences model-data fit. As expected, the consideration of simplicity strategies improved the model-data fit achieved for the instruction-based strategy.  相似文献

Abstract

Developmental researchers have demonstrated the potent role of a knowledge base on children's memory performance. However, the only studies to experimentally assess a causal connection between children's knowledge and memory have failed to find such connection (DeMarie-Dreblow, 1991; Muir-Broaddus, Rorer, Branden, & George, 1995). In this study, we extended the length of training relative to earlier studies with samples of first- and seventh-grade children, incorporating knowledge training into their school curriculum. Both groups of children displayed an increase in knowledge as a result of training and corresponding significant improvements in recall, consistent with a causal relation between knowledge and memory. Although we believe that some of the benefits for the older children were associated with improvements in strategic organization, most of the gains, for both the older and younger children, could be attributed to item-specific effects of knowledge on recall.  相似文献

ABSTRACT

As a consequence of worldwide waves of immigration there is a permanent increase of ethnically mixed school classes in countries all over the world. However, there is a lack of empirical studies on interethnic relationships which differentiate immigrant children based on their countries of origin. The present paper focuses on these topics and provides data of both negative and positive aspects of interethnic interactions. Direct and indirect forms of bullying, friendship patterns, and peer acceptance in 326 native and 242 immigrant children aged 11 to 14 (57% native Austrian, 22% former Yugoslavian, 14% Turkish/Kurdish, 7% rest group) in 29 ethnically mixed school classes (6th and 7th grades) were examined. Bullying was measured via the Olweus Bully/Victim Questionnaire and via peer nomination techniques, friendship patterns via self-ratings. Peer acceptance was defined by social preference scores on positive and negative sociometric items. According to peer ratings Austrian children were found to be more often victims (9%) and bullies (12%) of direct bullying than immigrant children. Prevalence rates in immigrant children varied depending on their country of origin between 2% and 8% for victims and 3% to 7% for bullies. Results suggested that Turkish/Kurdish children are at risk concerning their social integration in class (e.g., they had the fewest number of friends in class, reported higher levels of loneliness at school, and were less accepted by their peers compared to Austrians and former Yugoslavian children). Friendship patterns differed considerably between native children and children of the three immigrant groups. Findings are discussed concerning differences in integration strategies of immigrant children depending on their country of origin.  相似文献

Abstract

This study investigated the meaning of working for subjects from three levels of an organizational hierarchy. Staff members of a high technology manufacturing organization were surveyed using an abridged version of the Meaning of Working Questionnaire. Five central aspects of the ‘meaning of working’ concept were explored using this instrument, namely Work Centrality, Work Role Identification, Valued Working Outcomes, Societal Norms about Working, and Work Goals. Results show a high level of shared perceptions by members of the three hierarchical levels on ‘meaning of working’ variables, a finding which is at odds with past research, which for the most part indicates clear hierarchal effects. Such findings are discussed within the context of the internal processes of the organization as well as in a specific industry-wide framework.  相似文献

There are currently no guidelines available for enhancement of resilience in professional nurses. This study aims to provide broad guidelines with specific strategies that may enhance resilience and psycho-social well-being in professional nurses. These guidelines are based findings from previous qualitative research on resilience in professional nurses in the public and private sector in South Africa. We used Kumpfer's (1999) theoretical model of resilience to frame the guidelines. Resilience among professional nurses appears to vary in manifestation across settings of practice.  相似文献
