Comprehensive approaches to youth violence prevention are needed to simultaneously address multiple risk factors across socioecological levels. ThrYve (Together Helping Reduce Youth Violence for Equity) is a collaborative initiative focused on addressing broader factors influencing youth violence, including social determinants of health. Using a participatory approach, the development of ThrYve is examined through an empirical case study. Through a Systems Advisory Board (SAB), ThrYve deploys multiple strategies that support cross-sector collaboration involving over 40 partners across 13 community sectors. Based on the Institute of Medicine’s model for public health action in communities, the SAB identified 87 change levers (i.e., program, policy, practice changes) to support community and systems-level improvements. As a result of the collaborative process, in the first couple of years, ThrYve facilitated 85 community actions and changes across sectors. The changes aligned with identified risk and resilience needs of the youth served in the community. The findings further support prior research, which suggests disparities related to gender may influence risk and resilience factors for youth violence. The study also indicates the importance of continuing to examine academic performance as a factor related to youth resilience.  相似文献

Motor vehicle collisions involving older drivers have increased and become an important social issue. It is known that the decline of cognitive function, including dementia, affects driving performance. A series of studies using the Mini-Mental State Examination (MMSE) and other tests of dementia have attempted to prevent motor vehicle collisions by identifying as early as possible older drivers who may be unable to maintain their driving performance. Further, the performance of older drivers may deteriorate even if they do not have a diagnosis of dementia. Therefore we focused on the relationship between cognitive functioning assessed by the MMSE and diagnosis of leukoaraiosis (LA), or changes in the cerebral white matter, with different aspects of driving behavior resulting from aging. Qualified driving instructors evaluated participants’ driving behaviors on an outdoor driving course at a driving school. Visual search duration and angle at intersections were obtained by wearable wireless sensors. Vehicle speed and minimum vehicle speed were recorded from vehicle speed pulse signals. Duration of signaling and visual searches at unsignalized intersections were recorded using an in-vehicle camera. We assessed instructors’ evaluations and the scores on two instruments to evaluate the effects of MMSE scores and the grade of LA on driving performance were verified. The results suggest that lower MMSE scores and higher LA grade can predict some aspects of poor driving performance in older drivers before they experience dementia or an evident decline in cognitive functioning. Based on these results, we discuss countermeasures that may prevent motor vehicle collisions involving older drivers.  相似文献

This study examined the association of cigarette smoking status and body image dissatisfaction as measured by the Multidimensional Body-Self Relations Questionnaire (MBSRQ), in 1575 young adult college students, 18–24 years of age. Respondents were current cigarette smokers (N = 482) or never tobacco users (N = 1093). Smoking status was found to be significantly associated with 5 of the 10 MBSRQ subscales, with current smokers having lower scores on Fitness Orientation, Health Evaluation and Health Orientation (all p < 0.001) and higher scores on Appearance Orientation (p = 0.01) and Overweight Preoccupation (p = 0.03) compared with never tobacco users. Furthermore, among current smokers, a higher number of days smoked in the last 30 days were associated with lower scores on all MBSRQ subscales, except Self-Classified Weight. In terms of clinical implications, interventions for smoking cessation among college students might benefit from inclusion of components for addressing body image dissatisfaction and improving health beliefs.  相似文献

This paper presents a psychometric study performing a confirmatory factor analysis of Gismero's Social Skills Scale. A background review is conducted on evaluation tools generally used for social skills, and the general characteristics of the scale are presented for the tool studied. A review is also conducted on psychometric properties of this tool. The sample consisted of 1206 college students at the Universidad Católica de Temuco, Chile. Confirmatory factor analysis was conducted using a polychoric correlation matrix, and the structure proposed by Gismero was analyzed. Reliability assessment procedures, such as internal consistency (Ordinal Alpha) and discriminant validity analysis, were also conducted using AF5 factors. The results show good internal reliability of the tool, suitability of the model to the data, and good discriminant validity. In conclusion, the Gismero's Social Skills Scale is considered as a suitable tool for assessing social skills in Chilean university students. A slight modification of the model structure in the second order factor level is proposed.  相似文献

Fasting, or going a significant amount of time without food, is a predictor of eating pathology in at-risk samples. The current study examined whether acute changes in body image occur after an episode of fasting in college students. Furthermore, it evaluated whether individual difference variables might inform the relationship between fasting and shifts in body image. Participants (N = 186) included male (44.7%) and female college students who completed the Body Image States Scale (BISS) and other eating-related measures before a 24-h fast. Participants completed the BISS again after fasting. While no overall changes in BISS scores emerged during the study, some individuals evidenced body image improvement. Baseline levels of disinhibition and self-reported fasting at least once per week uniquely predicted improvement in body image. Individual difference variables may play a role in how fasting could be reinforced by shifts in body image.  相似文献

Natural mentors provide advice, moral support, and assistance to adolescents who aspire to obtain a postsecondary degree, but past studies of the benefits of having an informal adult mentor have yet to resolve several issues. Our analyses of a national sample of high school graduates test three hypotheses: (H1) natural mentoring increases the odds of college attendance and completion, (H2) guidance and career advice are more important for college success than encouragement or role modeling, and (H3) students from poor and working‐class families benefit more from mentoring than students from middle‐ and upper‐class families. Hypotheses 1 and 3 are clearly supported when examining the odds of attending college, while Hypothesis 2 was not supported—encouragement and role modeling boost attendance, not advice or practical help. None of the hypotheses is supported when predicting degree completion among those who matriculated. As natural mentors do not appreciably increase the odds of completing college, we conclude past studies have overstated the postsecondary educational benefits of natural mentors.  相似文献

本研究探索在通用认知诊断模型和相关检验方法的基础上对现有语言水平测验进行诊断改造和分析,分三步进行探索:1)探索对语言水平测试不同的属性和Q矩阵构建途径;2)探索对语言水平测试基于通用模型的建模和效度验证;3)探索对语言水平测试建模后续的深入分析。研究发现:属性分布和总分分布划分的学生水平一致性较高;学生对属性掌握存在性别差异且属性间的难易层级不同;属性模式分布进一步验证了语言属性间关联程度较高以及通用认知诊断模型和相关检验方法对语言测验的适用性。三步式的建模分析可作为对语言水平测验进行认知诊断改造的参考。  相似文献

The authors propose conceptual models linking trait emotional intelligence (TEI) with achievement both directly and indirectly via perceived social support (PSS), engagement coping (EC), and adjustment, in the context of the university transition. The models were tested in a multiwave design with a sample of incoming Australian undergraduates (N = 470). In structural equation analyses, TEI was found to be a direct predictor of higher PSS and the greater use of EC strategies. Further, mediation analyses revealed that TEI was indirectly associated with academic adjustment via EC and psychological adjustment via EC and PSS operating in parallel. TEI was also found to be indirectly associated with achievement via EC and academic adjustment linked serially in a three-path mediated sequence. These direct and indirect relations were robust when controlling for known confounding influences. The empirically supported mediating processes extend the literature by elucidating some of the pathways through which TEI is linked with better adjustment and achievement.  相似文献
