A meta-analysis of published studies on the clinical efficacy of selected self-help programs (F. Scogin et al; see record 1990-15222-001) indicated that such conditions were more effective than no-treatment controls. Calculation of a fail-safe N showed that 53 nonsignificant studies would have to exist to render the conclusions of the meta-analysis invalid. Results indicate that unpublished research is unlikely to threaten the validity of the original meta-analysis. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Entrepreneurs look to the future and see opportunity where others see barriers. They are proactive with the never-ending cycle of change, recognizing that change relocates opportunity. Nurse entrepreneurs make themselves aware of emerging health care trends, acquire the skills demanded by those trends, and arrive in the new era fully equipped to flourish. 相似文献
