SYNOPSIS

Objective . Most parents manage some degree of parenting stress without serious concerns, but young mothers experience parenting stress at higher levels than adult mothers; high parenting stress is problematic due to its association with children’s socioemotional and behavior problems and the increased likelihood of maltreatment. Understanding the circumstances that precipitate or mitigate parents’ stress can have lasting impacts for child well-being. Extant research fails to account for both longitudinal and individual variation in young mothers’ parenting stress, leading to equivocal findings about the nature of mothers’ parenting stress trajectories across early childhood. Design . The present study used growth mixture modeling (GMM) to model the trajectories of 544 first-time young mothers’ parenting stress from children’s infancy to school-age. We considered how protective factors (i.e., social support) and psychological vulnerabilities (i.e., depression) experienced during the transition to parenthood were associated with parenting stress trajectories and variation within trajectories when children were of school-age. Results . GMM identified three trajectories of parenting stress: “low stable”, “high increasing”, and “high decreasing.” Protective factors were related to low and decreasing patterns of parenting stress, whereas psychological vulnerabilities were associated with higher parenting stress patterns. Conclusions . This study has implications for programs and services that help young mothers cope with the demands of parenting and reduce parenting stress.  相似文献

There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important.  相似文献

The present study investigated preservice teachers’ self‐efficacy in classroom management involving students with symptoms of Attention Deficit/Hyperactivity Disorder (ADHD). A total of 137 Chinese preservice teachers were randomly presented with one of four vignettes involving a student character with ADHD symptoms, with manipulations including the character’s gender and diagnostic label of ADHD. Upon reading the vignette, participants responded to questions concerning their self‐efficacy in inclusive classroom management involving the character. Findings based on analysis of covariance indicated an interaction effect of the vignette character’s gender and label on teachers’ self‐efficacy. Specifically, teachers perceived greater self‐efficacy in a classroom involving a girl with an ADHD label than in a classroom involving a girl with no label or a boy with a label. Findings enriched the literature concerning the roles of gender and label in preservice teachers’ self‐efficacy toward inclusive classroom management.  相似文献

This article explores the findings of a small research study that asked writers to describe a meaningful, personal incident using first narrative and then poetic forms. The poetry raised many anxieties about writing, including the revelations of subjectivity and the risks in sharing such work with a group. To understand some of the complexities of these responses, the researchers thought of writing as an ecology with interdependent systems influencing the writing. Rereading the research texts, they traced some of those systems that affect students' writing and understanding of poetry.  相似文献

The aims of the EVINCE research projectincluded examination of the impact of information on the clinical knowledge and practice ofnurses, midwives and health visitors. EVINCE (Establishing the Value of Information to NursingContinuing Education) was funded by the British Library R&D Department for 1 year, from 1November 1995 to 31 October 1996. The methods employed (based on those used in the Valueproject) included a critical incident type study to establish patterns of information need and useamong a random sample of nursing professionals. The nature of the impact of informationobtained on present and future competencies was assessed from a survey of the searches andrequests presented to library and information services. Nurses, midwives and health visitors didvalue the information (96% of respondents agreed that there was, or would be an effect onfuture practice through enhanced competence in one or more areas). The impact findings can beused to guide a more precise assessment of information needs.  相似文献

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献

This study investigated the impact of an open inquiry experience on elementary science methods students’ understanding of celestial motion as well as the methods developed by students to answer their own research questions. Pre/post interviews and assessments were used to measure change in participants’ understanding (N = 18). A qualitative approach was used to describe the nature of each participant’s investigation through an analysis of their science journal and poster presentations. A comparison of participants’ inquiry projects with the change in their understanding revealed that while most participants improved in both their area of inquiry and beyond, elementary science methods students may need more guidance to reach a full scientific understanding across all aspects of celestial motion.  相似文献

Although the presence of toys in childhood has remained steady for decades, the types of toys that fill children's toy boxes have changed, especially over the last 10–15 years. Many of today's toys are marked by technological enhancements, from a shape sorter driven by a singing bear to robotic plastic animals designed to match a toddler's favorite television show. Although examining the effects of these changes is still an unexplored area, research to date suggests that there may be costs to the quality of caregiver–child interaction when using these toys together. This leads to two possibilities: (1) the design of the enhancements themselves hurt interactions; or (2) these toys can still be beneficial to interactions, but caregivers simply need to be aware of the potential pitfalls. In this study, we explore whether providing caregivers with a subtle cue about the potential negative impacts of technological toys on caregiver–child interaction affects their behavior.  相似文献
