Are Older Adults Less Or More Physiologically Reactive? A Meta-Analysis Of Age-Related Differences In Cardiovascular Reactivity To Laboratory Tasks, Wendy C. Birmingham, Bert N. Uchino, Cynthia A. Berg

In this meta-analytic review of 31 laboratory studies, we examined if relatively older adults showed lower or higher cardiovascular reactivity compared with relatively younger adults. Results revealed that age was associated with lower heart rate reactivity but higher systolic blood pressure (SBP) reactivity during emotionally evocative tasks. Consistent with the predictions of dynamic integration theory, the result for SBP was moderated by the degree of task activation. These data are discussed in light of existing self-regulatory models and important future research directions.


Estimating The Prevalence And Frequency Of The Adolescent Drug Use: Do The Models Fit The Measures?, John P. Hoffmann, Stephen J. Bahr Jan 2010

Estimating The Prevalence And Frequency Of The Adolescent Drug Use: Do The Models Fit The Measures?, John P. Hoffmann, Stephen J. Bahr

Faculty Publications

We critically review recent studies to examine the measurement schemes and empirical models used to examine adolescent drug use, with a particular eye toward determining whether differences between the prevalence and frequency of use have been addressed. Several theoretical models suggest that there are differences but we find relatively few studies that have considered prevalence versus frequency, even though selection effects that dictations these processes affect conclusions about predictors of drug use. Using data from the 2004 U.S. National Survey of Drug Use and Health (NSDUH), (n=16,235), we provide an empirical example of why distinguishing prevalence and frequency of use …
