Cognitive risk profiles for anxiety disorders in a high-risk population.

The purpose of the present study was to identify subgroups of participants who may be at particularly high risk for anxiety pathology based on specific combinations of demographic characteristics and higher-order cognitive abilities in a population at disproportionate risk for deficits in cognitive abilities (i.e., smokers within the criminal justice system).

How low should you go? Determining the optimal cutoff for exhaled carbon monoxide to confirm smoking abstinence when using cotinine as reference.
