This chapter first presents a review of research on the development of adopted children, focusing on meta‐analytic evidence and highlighting comparisons between adopted children with and without histories of early adversity. Some methodological issues arising from this literature are considered as well. Second, 7 longitudinal studies of adopted children's development are described, and the convergence of findings across the longitudinal studies and with the cross‐sectionally based meta‐analytic evidence is discussed. Third, the role of the adoptive family in supporting adopted children's development is explored. 相似文献

Objective
The extent to which existing and future research can impact on reducing health disparities relates not only to the evidence available, but the ability to find that evidence. Our objective is to quantify experts' literature searching effectiveness with respect to Aboriginal and Torres Strait Islander people's health.Methods
Nine journals were dual reviewed, and a ‘gold standard’ set of relevant articles was identified. Health librarians (n = 25) completed a standardised searching task using OVID MEDLINE, and results were compared with the gold standard. Sensitivity, specificity and precision rates were calculated.Results
The gold standard comprised 136 of 1469 (9.3%) records from nine journals. Searches achieved a mean sensitivity of 53.2% (median = 64.7%, range 0.0–93.4%), specificity of 97.4% (median = 99.4%, range 52.6–100%) and precision of 83.3% (median = 91.0%, range 16.7–100%). Self‐estimates of search sensitivity (post hoc) were significantly higher than observed (M = 78.9%, t = 4.812, P < 0.001).Conclusions
Even expert searchers struggle to find the relevant peer‐reviewed literature in MEDLINE.Implications
A search filter may improve searching effectiveness for Aboriginal and Torres Strait Islander health literature. Assessment of health librarians' searching competencies warrants further professional debate and consideration. 相似文献6.
Background/objectives: Methodological decisions made during the research process can influence generalizability of findings to real world practice. The aims of this study were to explore the impact of decisions made in the development of a palliative care search filter and to consider the implications for implementation. Methods: Three elements of the original study methodology were explored: (i) choice of OVID medline field delimiters; (ii) use of the general medical literature to evaluate the filter's performance; and (iii) use of the OVID interface. Sensitivity, specificity, accuracy and precision rates of variant search strategies were compared to consider each issue. Results: The delimiter .af. outperformed the alternatives of .tw. or .mp. in OVID medline , improving sensitivity from 45.4 to 46.2%. Applying the filter in the specialist palliative literature resulted in 87.5% (692/791) of articles being retrieved using either .tw. or .mp., increasing to 100% (791/791) with the .af. delimiter. Finally, a PubMed version of the filter was successfully validated. Conclusions: Reviewing three methodological decisions that preserved validity in an original study led to the improved utility of a search filter in practice. Generating high‐quality evidence is only part of evidence‐based practice: consideration of generalizability issues can inform further research and effective evidence implementation. 相似文献
