Given that physical activity (PA) tends to decrease with age during adolescence, addressing factors that affect change is important. This study examined the similarity and interdependence of PA as influenced by psychosocial factors among adolescent best friend dyads. A total of 660 adolescents, representing 330 best friend dyads, completed questionnaires with regard to PA, sitting time, perceived exercise benefits and barriers, physical self-perception and social support for PA. Dyads were also identified as reciprocal and non-reciprocal best friends; reciprocal means that both considered each other best friends and non-reciprocal were those in which only one considered the other a best friend. Data were analysed using a hierarchical linear model framework. Results indicated significant similarities between reciprocal best friend dyads for PA and sitting time, and for sitting time in non-reciprocal best friends (P values <.01). Psychosocial variables were associated with PA in reciprocal best friend dyads and with sitting time in reciprocal and non-reciprocal best friend dyads. Best friend gender, regular sports practice of the person, perceived exercise barriers of the best friend and best friend social support were the best predictors for PA. 相似文献

Effective educational leadership is essential for the success of schools and ultimately student achievement. The impact of school leadership may be even more pronounced in charter schools. Due to current and unprecedented growth, unique design, and complexities of political, financial, and governance issues they face, there is a need for more highly qualified charter school leaders and perhaps even “differently” prepared leaders. In this qualitative study, the authors documented the characteristics and skills of two successful, sustained charter school leaders who retrospectively described their evolved and evolving roles over twenty five years. Each transformed high-poverty, low-performing schools with at-risk populations and led with vision, passion, and a relentless desire to positively influence their organizations and ultimately improve student success in their communities. Although many of their skills and characteristics fall within existing theories, such as situational leadership, transformational leadership, and distributive leadership, they embodied a level of dedication and commitment to the original communities in which they founded charters lasting over a quarter of a century. The findings suggest that founding a charter school and seeing it through to success over time may more closely resemble missionary work than traditional school leadership. 相似文献

Objective
Young children involved with child welfare services are at high risk for behavior problems. This study aims to identify externalizing behavior paths that preschoolers in this high-risk population follow over a 6 year period, and the predictors of membership in normative and problematic pathways.Methods
Using data from the National Study of Child and Adolescent Well-being (NSCAW), the sample included 246 4-year-olds who remained home after investigation. Latent class growth analysis (LCGA) was used to estimate the number, size, and shape of subgroups of preschoolers following distinct behavioral pathways. Early predictors of membership in the resulting groups were then examined.Results
Four groups of preschool children following distinct behavior trajectories over 6 years were identified. Weighted results show that more than half (61%) of the children followed a low/normal problem behavior trajectory while just over one tenth (12%) were on a persistent high trajectory, remaining in the clinical range throughout the study. Improving (23%) and worsening (4%) problem behavior groups were also identified. Internalizing problems, attention problems, child ethnicity, and maltreatment type reported at age 4 predicted membership in the trajectory groups.Conclusions
Internalizing behavior problems and maltreatment type may distinguish preschool children who are more likely to experience worsening or persistent problematic externalizing behaviors from those likely to follow a normal behavior trajectory.Practice implications
Identifying early indicators of externalizing behavior problems and addressing them with evidence-based interventions to reduce negative behaviors may avert long-term negative outcomes. 相似文献4.

This study was designed to determine the predictive validity of selected admissions variables used by the University of Kentucky College of Medicine. Data for the study were collected from 586 students admitted to the M.D. program from 1961 to 1968. These students were categorized into one of three groups (Successful [SUCC], Successful with Extended Study [SWES], and Lost to Medicine [LTM]) based upon their performance in medical school. A two-way analysis of variance and the use of a post hoc Scheffé method of multiple comparisons indicated significant differences between the SUCC group and the combined SWES and LTM groups. Therefore, the data revealed the predictive ability of two admissions variables and suggested the need for additional research into the subjective variables used in the admissions process. 相似文献

In this article, we present an approach for comprehensive analysis of the effectiveness of interventions based on nonlinear structural equation mixture models (NSEMM). We provide definitions of average and conditional effects and show how they can be computed. We extend the traditional moderated regression approach to include latent continous and discrete (mixture) variables as well as their higher order interactions, quadratic or more general nonlinear relationships. This new approach can be considered a combination of the recently proposed EffectLiteR approach and the NSEMM approach. A key advantage of this synthesis is that it gives applied researchers the opportunity to gain greater insight into the effectiveness of the intervention. For example, it makes it possible to consider structural equation models for situations where the treatment is noneffective for extreme values of a latent covariate but is effective for medium values, as we illustrate using an example from the educational sciences. 相似文献

ABSTRACTThis special issue of JREE features studies from three of the teams (Barnes, Stuebing, Fletcher, Barth, & Francis; Language and Reading Research Consortium, Arthur, & Davis; LaRusso et al.) supported by the Institute of Education Sciences—Reading for Understanding Research (RFU) Initiative. Each study examined the importance of comprehension-related variables (i.e., academic language, perspective taking, complex reasoning skill, suppression, and response to instructional dosage) in developing readers. In this commentary we apply Perfetti and Adlof's (2012) concept of comprehension-related pressure points to help us assess whether the size of relation between the comprehension-related variables and reading comprehension skill are large enough to be of practical significance for assessment and intervention. In general, we conclude that none of the comprehension-related variables investigated in the special issue meet the criteria for inclusion as a pressure point. However, we caution that decontextualized assessments of potentially important comprehension-related skills applied as predictors to generic passage variance without concern for important reader-by-text interactions may result in underestimates of the importance of reader characteristics in certain texts. 相似文献

The study investigates parenting styles as predictors of anxiety and depression in secondary school students in Edo State, Nigeria. It employed a correlation research design. Two hundred and forty students constituted the sample for the study. Parenting Style Scale questionnaire was used to collect data for the study. Linear regression was used to analyse the data. The findings revealed that parenting styles (authoritarian, authoritative and permissive) significantly predict anxiety in adolescent secondary school students in Edo State. However, parenting styles did not significantly predict depression in adolescent secondary school students in Edo State. Based on these findings it was recommended among others that school counsellors should organise seminars and create awareness among parents and students on the influence of these parenting styles on the students and professional counselling intervention programmes were recommended for professional counselling practices. 相似文献

This study examined the extent to which students could fake responses on personality and approaches to studying questionnaires, and the effects of such responding on the validity of non-cognitive measures for predicting academic performance (AP). University students produced a profile of an ‘ideal’ student using the Big-Five personality taxonomy, which yielded a stereotype with low scores for Neuroticism, and high scores for the other four traits. A sub-set of participants were allocated to a condition in which they were instructed to fake their responses as University applicants, portraying themselves as positively as possible. Scores for these participants revealed higher scores than those in a control condition on measures of deep and strategic approaches to studying, but lower scores on the surface approach variable. Conscientiousness was a significant predictor of AP in both groups, but the predictive effect of approaches to studying variables and Openness to Experience identified in the control group was lower in the group who faked their responses. Non-cognitive psychometric measures can be valid predictors of AP, but scores on these measures can be affected by instructional set. Further implications for psychometric measurement in educational settings are discussed. 相似文献

Limited information on the actual and preferred career counseling and career testing activities of school counselors exists. An analysis of a statewide school counselors' survey revealed career counseling and testing preferences, priorities and predictors. Results revealed counselors preferred trait/factor approaches to career counseling, including Holland's RIASEC theory, Person-Environment-Correspondence theory and Cognitive Information Processing theory, respectively. With respect to career counseling and career testing priorities, means comparisons indicated that elementary, middle, and high school counselors' actual time performing career counseling duties is minimal; however, they desire to spend significantly more time on career counseling and testing. Multiple regressions revealed important predictor variables for actual and ideal time spent on career counseling and career testing. Limitations and recommendations for further research are discussed. 相似文献

Most longitudinal evidence explores the average level of development, suggesting that the relationships between a limited number of variables applies to all learners in the same way. This is the first longitudinal study that investigates multiple component numeric skills within a preschool population using a person-centered approach (i.e., a latent transition analysis), thus allowing for an investigation of different subgroup learning pathways of mathematical skills over time. 128 children aged 43–54 months (at Time 1) were tracked at three time points over 8 months encompassing the transition from preschool through to their first year of primary education. Findings suggest that there are five developmental pathways of mathematical learning with some groups of children making more rapid progress on entry to school than other groups. Those children in the low number skill pathway have a lower rate of growth than more advanced pathways, possibly due to a lack of understanding in cardinality. Findings highlighted the potential importance of language and working memory abilities on mathematical skills development over time. 相似文献
