The purpose of this study was to examine in a sample of 11,516 secondary school students the extent to which different behavioral, emotional and cognitive problems (a) reflected one or more underlying common factors; (b) actually cooccurred; and (c) were single problems. Principal Component Analyses were performed and percentagewise techniques were used. PCA demonstrated that one or more general syndromes could not by far account for all of the variance of the variables. The results suggest the existence of adolescent subgroups with divergent comorbidity patterns: those who primarily report one single symptom; those who report concurrent symptoms either exclusively in the category of behavioral problems or exclusively in the category of emotional and cognitive problems; and those who report concurrent symptoms in both categories. This distinction between different subgroups has important theoretical, diagnostic, and treatment implications.  相似文献

This article will trace the history and effects of the PPI from the time of its original concept by the FDA in the early 1970's to its current status. It will also address the response to this FDA initiative by the industry, medical community and consumer groups. Initiatives in other countries and future issues will also be discussed.  相似文献

Federalism enjoyed political and popular salience during theperiod 1996–1997 as the so-called "Devolution Revolution"began to be implemented and analyzed in the United States. Whilethere were a few examples of important Revolutionary efforts,the federal government continued to hold much of the power andsignificance it has achieved over the past sixty years. Evenin the area of welfare policy, where in 1996 there were historicreforms enacted to end the federal entitlement, the federalgovernment maintained a significant presence that made the ideaof devolution of welfare policy responsibility some what questionable.Nevertheless, states continued to lead in policy innovationin areas ranging from education to health, and the U.S. SupremeCourt continued to question the limits of federal power. Thepast year illustrated, once again, the complexity of our federalsystem and how difficult it is to reform federalism—particularlywhen it involves a shift in power and creates the perceptionof winners and losers.  相似文献
