Vascular response to cigarette smoking was measured by blood flow change by utilizing a photoelectric plethysmograph in 43 subjects. All subjects took part in a smoking control program consisting of self-monitoring for a two-week period. It was hypothesized that there would be a non- linear relationship between blood flow change and various measures of success in treatment. It was also hypothesized that a combination of predictor variables including blood flow change, number of years the subject had smoked, change in heart rate following smoking, age of the subject, and pre-treatment smoking rate would successfully predict success in this smoking treatment. A significant non-linear relationship was found between blood flow change and change in the number of cigarettes smoked from the beginning of the two-week treatment period to the end of the treatment phase of the study. Significant multiple correlations were found for the relationships of the pre-treatment smoking rate and magnitude of the blood flow change with post-treatment smoking rate and the smoking rate at four weeks after treatment.
