The odds ratio and its alternatives: Measure-specificity of effects

Andrew Tomarken, Vanderbilt Department of Psychology

The odds ratio (OR) is among the most commonly used statistical measures of association or effect. It is by far the most commonly reported measure when dependent variables are binary and it is ubiquitous in studies focusing on the association between risk factors and disease outcomes. Unfortunately, most scientists are largely unaware of the mathematical and statistical properties of the OR and its differences, strengths, and weaknesses relative to alternative measures. After discussing several historical reasons for the popularity of the OR, I will describe several common misinterpretations and mistaken assumptions made by researchers based on an ongoing review of published research in medical and psychological journals. At various points, comparisons will be made to two alternative measures of effect, the relative risk (RR) and the risk difference (RD). Two overriding points will be emphasized: (1) Conclusions about the nature, functional form, and magnitude of effects derived from the OR will often not generalize to alternatives. Thus exclusive reliance on the OR can provide a highly selective or even misleading picture of the phenomenon under study; and, (2) Different measures are sensitive to different features of data, and at a more fundamental level, may reflect differing -- yet almost always unstated -- assumptions about the nature of main effects and interactions. I will conclude that: (1) It is important for researchers to determine those measures and models that best fit the goals of the study, the conceptualization of risk, and other aspects of the substantive phenomenon under investigation; (2) In the absence of a clearly optimal choice, researchers should report multiple measures to provide a more complete picture of the effects of predictors on binary measures; and, (3) Researchers need to expand on the cryptic verbal descriptions typically offered to describe effects and to supplement the presentation with appropriate graphical and other tools.

Careers with the US Government: A Professional Development Workshop for Graduate Students and Postdoctoral Fellows in Psychological Sciences and Neuroscience

 Vicki Ahlstrom, Engineering Research Psychologist Federal Aviation Administration (FAA)

Friday March 20, 2015 Location TBA 4:00-6:00 p.m.

Vicki Ahlstrom is an Engineering Research Psychologist and Technical Lead for the Federal Aviation Administration (FAA) in the Human Factors Branch at the William J. Hughes Technical Center in Atlantic City. She is responsible for research and standards development related to air traffic systems. Vicki was in the graduate program in Psychology at Vanderbilt from 1992-1997 under the guidance of Randolph Blake. In addition to talking specifically about her own career path and past and present job responsibilities working for the FAA, she will talk in general about some of the kinds of jobs available for those with graduate degrees in psychology and neuroscience with federal government agencies, careers in government, how jobs are advertised, how job applicants are evaluated, and general tips when considering this possible career path.

Fostering ATTENTION for Human Needs

At the turn of the 20th century Attention was seen as the central topic in human psychology.  One hundred years later,  attentional  networks involved in selection of information, maintaining alertness,  self control, and management of emotions have been explored by brain imaging.   Understanding attention has become central to managing our electronic devices, raising our children and obtaining the most from reading, listening and searching our connected world.  This talk will review the connection of the brain’s attention networks to early development of self regulation in children, understanding issues in psychopathology, and in training the brain to improve learning and to foster self control of adults in our highly connected world.
