The benefits of parental involvement in children’s education have been well established but increasing evidence suggests that overparenting may have adverse effects on children. The question of whether excessive parental involvement hinders children’s academic and psychosocial development warrants further investigations. This study examined the associations of parental educational involvement at home and in school with academic performance and psychological health of 507 Chinese Grade 3 schoolchildren in Hong Kong. Parents reported on their level of involvement in children’s schooling and their children’s psychosocial issues. Children were surveyed to determine their school engagement, and their Chinese language and mathematics attainment was assessed. We also explored the underlying mechanism by testing children’s engagement with school as a mediator of the relationships. Our results showed that home-based parental educational involvement was positively associated with children’s language competence and psychosocial wellbeing, and the associations were linked through engaging children with school. However, the benefits reached a plateau at higher level of parental involvement in children’s learning at home. School-based parental involvement had an indirect effect on children’s prosocial behavior through school engagement. These findings highlight the significance of optimal level of parental involvement in children’s education at home for children’s development.  相似文献

Four to 5 % of cystic fibrosis (CF) patients are diagnosed as adults and often have subtler symptoms. Their siblings are at genetic risk to also have a subtler disease state. Diagnostic testing is recommended for siblings of newly diagnosed infants, but recommendations are less clear for later diagnoses. This study explored sibling testing recommendations in pediatric and adult practice using a survey that was emailed to CF clinicians. There were 58 respondents. Results revealed that 82.5% of pediatric and 36.4% of adult care respondents reported always recommending diagnostic testing for siblings of a newly diagnosed patient. In adult care, another 33.3% reported recommending diagnostic testing if the sibling has symptoms. In pediatric care, whether the sibling had newborn screening was most influential. Most pediatric respondents prefer the sweat chloride test, while 40% in adult practice prefer familial mutation analysis. Perceived barriers included cost, insurance coverage and logistical concerns in both settings, parental emotional state in pediatrics, and concern making recommendations for someone who is not the patient in adult care. Genetic counselors may be able to meet familial needs in CF care, including sibling testing. Many newly diagnosed patients/families do not see a genetic counselor, especially in adult care. These data reveal opportunities for practice guidelines and standardization.  相似文献

Human sexuality is not binary: this, although counter-intuitive initially, is a medical fact. Homo-sexuality was an anomaly under a M/F taxonomy, and so ‘unnatural’ and ‘an abomination’. It is a mere statistical anomaly: it is a fact of Nature, nevertheless. Doctrines of Natural Law must recognize that even if Nature is stable, the notion/word ‘Nature’ is a shifter. As medical and other sciences amend our understanding of Nature, the idea of ‘Nature’ shifts. Natural Law theory is – and must continue to be – based on Nature: the contents of the idea of ‘Nature’ change progressively. So must cultural attitudes.  相似文献

The purpose of this study was to examine the role of neighborhood disadvantage and perceptions of neighborhood on the development of aggressive behavior among a sample of urban low‐income African American middle school aged youth (mean age = 11.65 years). Results of hierarchical linear modeling indicated that youth experienced significant changes in rates of aggression across the three middle school years, and that on average, negative youth perceptions of neighborhood predicted increases in aggression. Both parent and youth perceptions of neighborhood disadvantage trended toward significance as a moderator between objective neighborhood characteristics and aggression. These results are in accordance with past research, which suggests that personal evaluations of the disadvantage of a neighborhood influence child development and behavior. Future studies should examine the role that perceptions play in youth development, as well as in interventions geared towards thwarting youth aggression.  相似文献

A randomized trial compared effects of a Family Critical Time Intervention (FCTI) to usual care for children in 200 newly homeless families in which mothers had diagnosable mental illness or substance problems. Adapted from an evidence‐based practice to prevent chronic homelessness for adults with mental illnesses, FCTI combines housing and structured, time‐limited case management to connect families leaving shelter with community services. Families were followed at five time points over 24 months. Data on 311 children—99 ages 1.5–5 years, 113 ages 6–10 years, and 99 ages 11–16 years—included mother‐, teacher‐, and child‐reports of mental health, school experiences, and psychosocial well‐being. Analyses used hierarchical linear modeling to investigate intervention effects and changes in child functioning over time. Referral to FCTI reduced internalizing and externalizing problems in preschool‐aged children and externalizing for adolescents 11–16. The intervention led to declines in self‐reported school troubles for children 6–10 and 11–16. Both experimental and control children in all age groups showed reductions in symptoms over time. Although experimental results were scattered, they suggest that FCTI has the potential to improve mental health and school outcomes for children experiencing homelessness.  相似文献

This collective case study investigated the experiences of bilingual counselors‐in‐training who assessed school‐wide cultural competence in public schools. Analysis and interpretation of data resulted in the identification of 5 themes: eye‐opening experiences, recognition of strengths, the role of school leaders, road maps for change, and empowering marginalized groups. Implications and recommendations are discussed. Este estudio de caso colectivo investigó las experiencias de consejeros bilingües en formación que evaluaron la competencia cultural institucional en escuelas públicas. El análisis e interpretación de los datos dieron como resultado la identificación de 5 temas: experiencias reveladoras, reconocimiento de puntos fuertes, el papel de los líderes académicos, hojas de ruta para el cambio y empoderamiento de grupos marginalizados. Se discuten las implicaciones y recomendaciones.  相似文献
