ABSTRACT
The aim of the present investigation was to extend previous work on anxiety sensitivity (AS) and early smoking relapse among a sample of 130 (74 females) young adult (M (age) = 22.5 years, SD = 2.1) daily low-level smokers (9.3 cigarettes/day, SD = 11.5) from Mexico City, Mexico. Results indicated that of the global-level and lower-order factors (i.e., physical, mental incapacitation, and social concerns) on the Anxiety Sensitivity Index, only the physical concerns factor was significantly related to early lifetime smoking relapse. This effect was observed above and beyond the effects of negative affectivity, cigarettes smoked per day, and alcohol consumption, as well as beyond the other AS mental and social concerns factors. Findings provide novel evidence that AS is an important explanatory construct in early smoking relapse.

Taxometric coherent cut kinetic analyses were used to test the latent structure of anxiety sensitivity in samples from North America (Canada and United States of America), France, Mexico, Spain, and The Netherlands (total n = 2741). Anxiety sensitivity was indexed by the 36-item Anxiety Sensitivity Index--Revised (ASI-R; [J. Anxiety Disord. 12(5) (1998) 463]). Four manifest indicators of anxiety sensitivity were constructed using the ASI-R: fear of cardiovascular symptoms, fear of respiratory symptoms, fear of publicly observable anxiety reactions, and fear of mental incapacitation. Results from MAXCOV-HITMAX, internal consistency tests, analyses of simulated Monte Carlo data, and a MAMBAC external consistency test indicated that the latent structure of anxiety sensitivity was taxonic in each of the samples. The estimated base rate of the anxiety sensitivity taxon differed slightly between nations, ranging from 11.5 to 21.5%. In general, the four ASI-R based manifest indicators showed high levels of validity. Results are discussed in relation to the conceptual understanding of anxiety sensitivity, with specific emphasis on theoretical refinement of the construct.
