Associations of Personality Variables with Smoking Behavior and Pulmonary Function

Abstract

Interindividual variability of lung function responses to smoking is unexplained. The aim of the present study is to inquire about a possible role of personality factors for an explanation of interindividual differences of lung function responses in smokers of both sexes. The results of canonical correlation analyses showed that there are no substantial correlations of personality with smoking behavior and also no significant associations of smoking behavior with pulmonary function in a healthy sample of smokers. In males only, personality factors were related to breathing frequency, but not to static and dynamic lung volumes.
