Developing multicomponent interventions using fractional factorial designs
(John Wiley & Sons, Ltd., 2009-09-20)
Multicomponent interventions composed of behavioral, delivery, or implementation factors in addition to medications are becoming increasingly common in health sciences. A natural experimental approach to developing and ...
Cancer-specific worry interference in women attending a breast and ovarian cancer risk evaluation program: impact on emotional distress and health functioning
(John Wiley & Sons, Ltd., 2001-09)
Intrusive thoughts about cancer, often identified as ‘cancer-specific worries’ or ‘cancer-specific distress’, have been postulated to be associated with dysfunction in women at increased risk of developing breast or ovarian ...
A Conceptual Framework for Adaptive Preventive Interventions
(Kluwer Academic Publishers-Plenum Publishers; Society for Prevention Research ; Springer Science+Business Media, 2004-09)
Recently, adaptive interventions have emerged as a new perspective on prevention and treatment. Adaptive interventions resemble clinical practice in that different dosages of certain prevention or treatment components are ...
Rural motor vehicle crash mortality: The role of crash severity and medical resources
(Elsevier, 1992-12)
We did a retrospective case control study to examine the relationship between the risk of dying for Michigan motor vehicle crash (MVC) drivers and the type of county (rural/nonrural) of crash occurrence, while adjusting ...
Balanced centralized and distributed database design in a clinical research environment
(John Wiley & Sons, Ltd., 2000-06-15)
Clinical research databases can meet both research and clinical needs, but this ideal is seldom achieved. Priorities often differ for those who collect and ultimately use the data and those who develop data systems. ...
Assessing the Total Effect of Time-Varying Predictors in Prevention Research
(Kluwer Academic Publishers-Plenum Publishers; Society for Prevention Research ; Springer Science+Business Media, 2006-03)
Observational data are often used to address prevention questions such as, “If alcohol initiation could be delayed, would that in turn cause a delay in marijuana initiation?” This question is concerned with the total causal ...
On weighting the rates in non-response weights
(John Wiley & Sons, Ltd., 2003-05-15)
A basic estimation strategy in sample surveys is to weight units inversely proportional to the probability of selection and response. Response weights in this method are usually estimated by the inverse of the sample-weighted ...
The age structure of populations of Saccharomyces cerevisiae
(Elsevier, 1981-04)
A discrete deterministic model is described for the growth of an age-structured population of yeast, Saccharomyces cerevisiae, incorporating recent information on the asymmetry of cell division and control of the cell cycle ...
On summary measures analysis of the linear mixed effects model for repeated measures when data are not missing completely at random
(John Wiley & Sons, Ltd., 1999-09-15)
Subjects often drop out of longitudinal studies prematurely, yielding unbalanced data with unequal numbers of measures for each subject. A simple and convenient approach to analysis is to develop summary measures for each ...
