Design and Analysis of Group-randomized Trials - David M ... - 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 (, schools, worksites) and the units of observation are members of those groups (, students, workers).

Parallel Group Designs - Clinical Trials - Mussen Healthcare - A parallel group design is a complete randomized design in which each patient receives one and only one treatment in a random fashion. Basically there are two types of parallel group design for comparative clinical trials, namely, group comparison (or parallel-group) designs and matched pairs parallel designs. The simplest group comparison parallel group design is the two-group parallel design ...

The methods literature for these trials has grown steadily since they were introduced to the biomedical research community in the late 1970s, and we summarize those developments. We review, in addition to the group-randomized trial, methods for two closely related designs, the ...

Design and Analysis of Group-Randomized Trials: A Review ... - We review recent developments in the design and analysis of group-randomized trials (GRTs). Regarding design, we summarize developments in estimates of intraclass correlation, power analysis, matched designs, designs involving one group per condition, and designs in which individuals are randomized to receive treatments in groups.

Customer reviews: Design and Analysis of Group ... - Group-randomized trials are trials in which randomization takes place at a level higher than the individual subject. For example, for logistical reasons a comparison of two programs might be undertaken by randomizing communities to program, in which case the community rather than the resident is the unit of analysis.

Design and analysis of group-randomized trials (Book, 1998 ... - Abstract: This is the first comprehensive text about the design and analysis of community or group-randomized trials, which are usually done to evaluate the effect of health promotion efforts. It reviews the. underlying issues, describes the most widely used research designs, and presents the many approaches to analysis that are now available.

Randomized Controlled Trial - Study Design 101 - Definition A study design that randomly assigns participants into an experimental group or a control group. As the study is conducted, the only expected difference between the control and experimental groups in a randomized controlled trial (RCT) is the outcome variable being studied.

An evaluation of constrained randomization for the design ... - Group‐randomized trials are randomized studies that allocate intact groups of individuals to different comparison arms. A frequent practical limitation to adopting such research designs is that only a limited number of groups may be available, and therefore, simple randomization is unable to adequately balance multiple group‐level covariates between arms.

Design and Analysis of Group-Randomized Trials: A Review ... - We reviewed group-randomized trials (GRTs) published in the American Journal of Public Health and Preventive Medicine from 1998 through 2002 and estimated the proportion of GRTs that employ appropriate methods for design and analysis..
