Children as pedestrians are one of the most vulnerable groups of road users. Therefore factors associated with risky pedestrian behaviour should be carefully studied. The aim of this article is to clarify how the traffic behaviour of 6th grade students as pedestrians is associated with the behaviour of their traffic companions and prevention activities at school, also taking gender into consideration. The research was conducted based on a randomly-selected sample of 1033 6th-grade students with the mean age of 12.77 ± 0.38 (SD) years. The results showed that compared to girls boys take significantly more risks as pedestrians: they rarely use reflectors during periods of darkness and often cross the road against the red light. The most important role models for adolescents in traffic behaviour are their parents. The role model behaviour with the strongest effect on adolescent high-risk behaviour in traffic is the role model not using crosswalks to cross the street. The results also showed that higher-risk traffic behaviour by adolescent pedestrians is predicted by higher-risk behaviour on the part of their companions (parents, teachers), walking alone on the street, as well as by an adolescent’s lower involvement in the less active prevention activities in the classroom. To improve adolescent pedestrians’ traffic behaviour social environment and school-based factors should be considered more thoroughly in prevention work at school.  相似文献

Contingency is an important cue to causation. Research shows that people unequally weight the cells of a 2 × 2 contingency table as follows: cause-present/effect-present (A) > cause-present/effect-absent (B) > cause-absent/effect-present (C) > cause-absent/effect-absent (D). Although some models of causal judgement can accommodate that fact, most of them assume that the weighting of information is invariant as a function of whether one is assessing a hypothesized generative versus preventive relationship. An experiment was conducted that tested the hypothesis-independence assumption against the predictions of a novel weighted-positive-test-strategy account, which predicts hypothesis dependence in cell weighting. Supporting that account, judgements of hypothesized generative causes showed the standard A > B > C > D inequality, but judgements of hypothesized preventive causes showed the predicted B > A > D > C inequality. The findings reveal that cell weighting in causal judgement is both unequal and hypothesis dependent.  相似文献

This study was designed to investigate the relationship between sexuality and exercise motivations in 93 British bar staff. Participants who self-identified as heterosexual, gay, or lesbian completed the revised version of the Exercise Motivations Inventory and reported exercise frequency. Heterosexual men scored lower on appearance motives than did heterosexual women and gay men, higher on enjoyment motives than did gay men, and higher on competition motives than did women and gay men. Men were significantly less likely than women to be motivated by weight management. Heterosexual men also reported exercising significantly more frequently than the other three groups. Suggestions for targeted exercise promotion initiatives are discussed.  相似文献

Whilst some individuals exercise for health-related reasons, others appear to exercise to bolster physical attractiveness. For the latter, this is often attributed to dissatisfaction with appearance. Few studies, however, have explored if differences in self-esteem may relate to diverse exercise reasons. The present study investigated whether global self-esteem, appearance-contingent self-worth, and appearance satisfaction may be differentially associated with health and attractiveness exercise reasons. It was further sought to explore whether these relations coincided with different motivational regulations. Adults from the east midlands of the United Kingdom (N = 209; 75% female, 25% male; mean age = 29.77 years) completed measures relating to their global and appearance-contingent self-esteem, appearance satisfaction, exercise intentions, and motivations. Structural equation modelling revealed that global self-esteem was positively associated with appearance satisfaction and health reasons for exercise, whereas appearance-contingent self-esteem related to lower appearance satisfaction and attractiveness reasons. Appearance satisfaction had no association with either exercise reason but was associated with intrinsic motivation and lower controlled exercise motivations. Health exercise reasons were positively associated with intrinsic, identified, and introjected motivation, whereas attractiveness reasons were exclusively related to external motivation. The findings highlight the conceptual importance of differentiating the level and contingency of exercisers’ self-esteem. The findings may also have substantive value for exercise practitioners in understanding different reasons for exercise.  相似文献

Social science research and clinical literature concur with our experience as providers of psychoeducational and clinical services: Postpartum depression results from the interplay of a multitude of individual and contextual factors. In light of the extensive literature on postpartum depression, it is surprising that models for prevention have not been established. We propose a model for prevention through integrated care and support, in which a wide range of existing services are used. This model is similar to comprehensive prevention models proposed by advocates of integrated service systems, such as community mental health and family support. The article includes illustrative case material.  相似文献

In the present review, we summarize the extant literature in the field of delinquency prevention. We do not provide a recounting of whether specific programs have or have not been effective but, rather, attempt to judge the overall utility of programs to prevent delinquency in its various forms and among various definable groups. Specifically, we organize our review of programs according to the characteristics of the targeted population, differentiating programs for universal, selected, or indicated populations. Within each population type, we further distinguish programs according to designated intervention context, relying on a biopsychosocial model that specifies four levels of influence on risk for delinquency: individual, close interpersonal relationships, proximal social settings, and societal macrosystems. At each level, we identify a number of effective intervention strategies and highlight those that are based on relevant risk factor research. As we note, the effectiveness of some approaches depends on the specific population, although, in general, multicomponent, multilevel programs appear to have the most substantial effects.  相似文献

We investigated whether (a) depression prevention was associated with depressive symptoms and medial-frontal alpha asymmetry in adolescents; (b) alpha asymmetry mediated the association between participation in a prevention program and depressive symptoms; and (c) gender affects these associations. In our randomised control group study, we compared a universal prevention program (n = 40 adolescents, 14 females) with a non-intervention control condition (n = 39 adolescents, 20 females) in German secondary school students (mean age: 13.53 years, SD = 0.53). We collected data at baseline, post-intervention, 6-month, and 12-month follow-up using the Self-Rating Questionnaire for Depressive Disorders (SBB-DES) and resting medial-frontal alpha activity on F3 and F4. We found that girls benefitted from participating in the prevention program in regards to their depressive symptoms at 12-month follow-up but not alpha asymmetry. In boys, participation in the prevention program was associated with their alpha asymmetry at 6-month follow-up but not their depressive symptoms. Alpha asymmetry did not mediate the effects of the prevention program on depressive symptoms in either gender. Although participation in the prevention program was associated with both depressive symptoms and alpha asymmetry, those associations seem independent from each other. Possible explanations for this result pattern are discussed.  相似文献

Guyana, a low-to-middle-income country (LMIC) in South America, leads the world in youth suicide. As an understanding of risk and protective factors is critical to the development of culturally informed suicide prevention efforts, research exploring these factors among youth in Guyana is needed. The current study expands on current research on adolescent suicide in Guyana and LMICs broadly by using qualitative focus groups and interviews to explore adult stakeholders' and youth's perspectives. Participants included 17 adult stakeholders and 40 adolescents in Guyana. Data were analysed using a grounded theory approach. Themes related to participants' perceptions of risk factors for suicide included demographic characteristics, pressure and expectations, adults' responses to youth, limited coping with stressful life events and exposure to suicide. Themes related to protective factors for suicide included positive social support and involvement in community activities. Findings have implications for the development and tailoring of suicide prevention efforts for Guyanese youth.  相似文献

The introduction to the EJSP special issue brings together recent literature on allyship. We present and discuss different definitions of allyship and highlight a multiple perspectives approach to understanding the predictors and consequences of allyship. This approach suggests that engagement in allyship can be driven by egalitarian and non-egalitarian motivations and that the behaviours identified as allyship can have different meanings, causes and consequences depending on whether researchers take into account the allies’ perspective or the disadvantaged groups’ perspective. We use this approach as an organizing principle to identify themes that emerge in the papers included in this special issue. We start with four papers that consider the perspective of the advantaged group, followed by two papers that consider the perspective of the disadvantaged group. Finally, we introduce two theoretical papers that examine the relations between disadvantaged groups and allies, and we set out directions for future research.  相似文献
