The study investigated comorbid Attention-Deficit/Hyperactivity Disorder (ADHD) and depression in a sample of rural primary school children in Limpopo Province, South Africa. A total of 320 learners participated in this study of whom 160 learners had teacher and parent identified ADHD symptoms (females?=?50%; age range 6–14 years). All the learners took the Beck Depression Youth Inventory, second edition. Data were analysed applying ANOVA to investigate the possible differences between and within age, gender, and ADHD subtype group differences in depression symptomatology. Results indicated no statistically significant differences in the scores on the depression scale between the children with ADHD as identified by parents and teachers and the comparison group peers.  相似文献

ObjectivesThis study examined mediation effects of socio-ecological variables on accelerometer-determined physical activity among children in the Supporting Children's Outcomes using Rewards, Exercise and Skills (SCORES) intervention.DesignRandomized control trial mediation analysis.MethodsPrimary school children were randomly assigned the SCORES multi-component intervention or control group for the 12-month study. The outcome was accelerometer derived total moderate-to-vigorous physical activity (MVPA). Hypothesized mediators measured in children were physical activity enjoyment and perceived sport competence and social support. Hypothesized mediators measured in parents were family social support, access to physical activity facilities and equipment at home, and perceived access to physical activity opportunities in the local community. Mediation analyses were conducted using multi-level linear analysis in MPlus.ResultsThere were significant intervention effects for social support from teachers (A = 1.73, SE = 0.88, p = 0.048) and parental perceived access to physical opportunities in the local community (A = 2.69, SE = 1.12, p = 0.016). There were significant associations between changes in perceived sport competence (B = 0.48, SE = 0.36, p = 0.027), parental perceived access to physical activity opportunities in the local community (B = 0.60, SE = 0.26, p = 0.021), and changes in total MVPA. Parental perceived access to physical activity opportunities in the local community was found to have a significant mediating effect on total MVPA (AB = 1.61, 95% CI = 0.06 to 3.95, proportion 13%).ConclusionsParental perceived access to physical activity opportunities in the local community is a potential mechanism of behavior change for children and mediated the effect of the SCORES intervention on objectively measured physical activity.  相似文献

Research on the effects of physical activity on children with attention deficit hyperactivity disorder is promising, yet no attempt has been made to integrate current findings using meta-analytic techniques. Using a meta-regression, the present study examined the effectives of physical activity for children with attention deficit hyperactivity disorder on a number of cognitive, behavioral, and emotional outcomes. From 20 empirical studies, 164 effect sizes quantifying the effectiveness of physical activity for children with attention deficit hyperactivity disorder were extracted from 22 independent samples. Results indicated an overall moderate-to-large effect for physical activity on children with attention deficit hyperactivity disorder, with a significant effect for emotion/mood. Limitations of the study, future directions, and implications for school professionals are discussed.  相似文献

ABSTRACT

Recent health care reform provides many new opportunities to expand mental health and behavioral support to students in schools and school–community partnerships. Through newly available funding sources, as well as expanded legislative initiatives, school psychologists can advocate for and become leaders in delivering universal programming, tiered mental health supports, and formalized collaborative efforts with community agencies. The authors highlight the application of tiered levels of services, with current practice samples, designed to address students' mental and behavioral health. Implications for practice are discussed.  相似文献

School burnout is defined as exhaustion, cynicism and inadequacy as a student, and engagement can be conceptualized as study-related vigor, absorption and dedication. School burnout is increasing, particularly among students on an academic track, while at the end of elementary school almost half of the students no longer find school meaningful. School burnout and engagement were investigated by applying the demand-resource and stage-environment models. The results show that high school demands lead to burnout, while personal and school resources lead to school engagement. Burnout from school-context can also spillover to later depression, drop out and internet addiction, and engagement to overall satisfaction with life and success in educational pathways. In line with the stage-environment fit theory, educational transitions play a role in changes in school burnout trajectories. Adoption of a person-oriented approach revealed several different burnout-engagement profiles, including a profile in which students are at the same time both exhausted and engaged. The social context of peers, immigrant status, parents and teachers also play an important role in engagement and burnout.  相似文献

Self‐determined learning is essential to academic success. The motivational resources development model argues that parents promote academic success in their children indirectly by nurturing self‐determined learner. In this study, applying a structural equation modelling and using data collected from 8th graders in Zhuhai, China (n = 1009) in 2012, we aim to answer 2 research questions: (a) What forms of parental involvement are highly correlated with self‐determined learning and (b) Can self‐determined learning fully mediate the relationship between parental involvement and students' academic performance? We find that parental leisure involvement is positively and significantly associated with the development of self‐determined learning, which in turn is significantly and positively correlated with academic achievement. Parental provision of structure or parental academic assistance is not significantly associated with students' self‐regulation and students' academic achievement.  相似文献

Black Mountain College is remembered as an artistic utopian alternative to institutional learning. Its faculty and students included some of the most important creative thinkers of the 20th century. Its foundation was built on the philosophy of “learning by doing.” But what made Black Mountain such a dynamic educational environment? Today, the financial burden of higher education places a lasting strain on students that inhibits creative growth. Does the educational structure of the college system impede our learning? Black Mountain was a legendary educational experiment, which offers a model for contemporary art education.  相似文献

This research examined whether induced joy influences fifth graders’ performance in literacy tasks. Children were asked to recall a joyful experience, used as a joy induction, before completing either a grammar (Study 1) or textual comprehension task (Study 2). The grammar task involved understanding at the surface level and retrieval of appropriate declarative and procedural knowledge, but limited elaboration unlike the textual comprehension task, which tackled inference generation. By differentiating tasks based on depth of processing required for completion we aimed at testing the validity of two concurrent hypotheses: that of a facilitating effect and that of a detrimental effect of induced joy. Compared to controls, joy induced children showed better performance on the grammar task – specifically children with lower language ability. No differences across groups emerged as a function of joy induction on the text comprehension task. Results are discussed with respect to emotion effects on cognition.  相似文献

This study tested a parent empowerment framework using a national sample of 9,982 parents from the Parent and Family Involvement Survey (National Center for Education Statistics, 2007 ) to investigate relationships between parent empowerment and children's academic performance. A multinomial logistic regression demonstrated significant relationships between parents' competence, self‐determination, community belonging, community participation, and academic performance, which differentiate among parents based on racial/ethnic, language, and socioeconomic backgrounds. Findings highlight the importance of parent empowerment interventions that consider structural barriers in schools.  相似文献

The Irish Education Act (Government of Ireland 1998) stipulates that each young person in secondary school in Ireland is entitled to access ‘appropriate’ guidance. It has been argued that this very right has been eroded since Budget 2012, where resource re-allocations in guidance counselling are obstructing the requirement for schools to implement this section of the Act. This qualitative study explored the effects of ‘educational cutbacks’ from the perspective of guidance counsellors. Findings from interviews with guidance counsellors, suggest that the effects of such cutbacks in guidance counselling are far-reaching and ultimately students are the one’s losing out. The paper proposes that there is a need to reinstate guidance counselling hours to allow guidance counsellors provide a comprehensive service to young people – which they are entitled to.  相似文献
