Design and Analysis of Group-randomized Trials
Design and Analysis of Group-randomized Trials by David M. Murray, published by Oxford University Press in 1998, is a comprehensive resource that delves into the design and analytic issues associated with group-randomized trials. This edition spans 467 pages and is presented in English, focusing on the evaluation of health promotion interventions where identifiable groups serve as the units of assignment. The book covers various research designs and analytic strategies, emphasizing mixed-model regression techniques.
Readers will find an in-depth exploration of the complexities involved in conducting comparative studies, particularly in the fields of medical research, epidemiology, and public health. The text includes detailed discussions on analytic methods using SAS PROC MIXED and GLIMMIX, as well as a thorough chapter dedicated to power analysis and sample size calculation. This resource is particularly relevant for those interested in clinical medicine and health care delivery, providing essential insights into the methodologies used in group-randomized trials.
Official synopsis Publisher
This text provides the most comprehensive treatment of the design and analytic issues involved in group-randomized trials. GRTs are comparative studies conducted to evaluate the effect of a health promotion intervention in which the units of assignment are identifiable groups (e.g., schools, worksites) and the units of observation are members of those groups (e.g., students, workers). The book reviews the underlying issues, the most widely used research designs, and analytic strategies. There is an emphasis on mixed-model regression, with two chapters illustrating the analytic methods in SAS PROC MIXED and GLIMMIX. There is also a detailed chapter on power analysis and sample size calculation.
