Psychophysiological interactions between smoking and stress coping?
Earlier studies with different types of stressors suggested that cigarette smoking might selectively dampen physiological stress reactions in passive rather than in active coping situations. This hypothesis was tested in the present study using the same task for both types of coping, but with two different instructions. Twenty-four female regular smokers were assigned either to a group requiring active coping or to a group requiring passive coping with ongoing electric shocks, and tested in two sessions where they performed a pre- and a postsmoking/non-smoking trial of the rapid information processing task (RIP). Smoking increased RIP task performance, cardiovascular and electrocortical arousal, and reduced anxiety throughout the session. Active coping, as compared to passive coping, produced greater increases in heart rate and blood pressure, a greater pre- to post-treatment decrease in reaction time and higher pain ratings of the electrical shocks. However, interactions between the effects of smoking and the type of coping were few and did not suggest a plausible concept. Thus, it was concluded that, although the typical effects of smoking as well as the differentiation between active and passive coping seen earlier with the same paradigm were confirmed, cigarette smoking did not affect the effects of the two coping conditions in a differential way.
