The current study explored the influence of three methods of parental emotion discourse (structured story-telling, reminiscing, and picture book) and their relation to preschoolers’ emotion understanding. Thirty-seven families participated in the study. Analyses showed that the structured story-telling method produced more emotion words, was high in unique emotion words, and was high for both emotion labelling and explanations. All three methods showed some potential to predict preschooler’s emotion understanding. Structured story-telling was best at predicting role-taking, while reminiscing and the picture book both were better at predicting situation knowledge. Additional studies are needed to further explore the influence of different methods of assessing emotion discourse to enhance validity and reliability of research in this field.  相似文献

BackgroundHealth and recreation practitioners play an important role in promoting and supporting leisure time physical activity (LTPA) among persons with physical disabilities (PWPD), yet many practitioners lack training and education to provide the basic knowledge, skills, and resources necessary.1 Little is known about existing LTPA information and training resources for health and recreation practitioners and there has been no known systematic effort to identify existing resources.ObjectiveThe purpose of the current study was to engage systematic scoping methodologies to identify resources that target the training and education of health and recreation practitioners to promote and support LTPA among PWPD. To further analyze the identified resources, an assessment of quality was conducted.MethodsSystematic scoping review methodologies were employed, which included searches of academic and grey literature, online materials (i.e., Google search) and expert consultation. Results: Several (N = 46) resources were identified from academic, government and non-government, and professional organizations. Most resources were targeted to a specific PWPD population. The resources were of high technical quality. Conclusion: The paper serves as a listing of existing resources for practitioners working with PWPD in LTPA settings. The review provides a catalyst for action in further research and practice regarding the analysis, design, development, implementation and evaluation of optimally effective resources targeting practitioners to promote and support LTPA among PWPD.ResultsSeveral (N = 46) resources were identified from academic, government and non-government, and professional organizations.

Objective: To identify behavioural barriers of service provision within general practice that may be impacting the vaccination coverage rates of Aboriginal children in Perth, Western Australia (WA). Methods: A purposive developed survey was distributed to 316 general practices across Perth and three key informant interviews were conducted using a mixed‐methods approach. Results: Of the surveyed participants (n=101), 67.4% were unaware of the low vaccination coverage in Aboriginal children; 64.8% had not received cultural sensitivity training in their workplace and 46.8% reported having inadequate time to follow up overdue child vaccinations. Opportunistic vaccination was not routinely performed by 30.8% of participants. Key themes identified in the interviews were awareness, inclusion and cultural safety. Conclusion: Inadequate awareness of the current rates, in association with a lack of cultural safety training, follow‐up and opportunistic practice, may be preventing greater vaccination uptake in Aboriginal children in Perth. Cultural safety is a critical component of the acceptability and accessibility of services; lack of awareness may restrict the development of strategies designed to equitably address low coverage. Implications: The findings of this study provide an opportunity to raise awareness among clinicians in general practice and inform future strategies to equitably deliver targeted vaccination services to Aboriginal children.  相似文献
