Description: This comparative investigation of smokers' "in-process decision making" about quitting investigated the relationship of eight decision-making elements, theoretically derived from Janis and Mann's conflict theory of decision making, Becker's health decision model, and Fishbein and Ajzen's theory of reasoned action. Subjects, 80 men and women, 30-44 years old, smoking at least 15 cigarettes per day, divided themselves into one of two groups: Not presently considering quitting or Presently considering quitting. Validity of group categorizations was established through concurrent measures as well as a six month follow-up of reported attempts to quit. A four-part researcher developed questionnaire using different question formats and incorporating a subjective expected utility framework was used to measure eight targeted elements of decision making: perceived susceptibility, barriers to quitting, non health benefits of quitting, normative influence, prevalence of smoking within the smoker's social milieu, self-efficacy, consistency between smoking and one's ideas and beliefs about the self, and recent experiences with negative health events.

Kendall's tau correlations between subjects considering quitting status and the decision-making elements revealed that, with respect to smokers not considering, those considering quitting scored significantly higher on measures of perceived susceptibility, normative influence, and experiences of negative life events, but significantly lower on measures of perceived barriers to quitting, prevalence of smoking within the social environment, and consistency with ideas and beliefs about the self. A discriminant analysis function was used to test the ability of the health decision model to predict whether or not smokers were considering quitting. When perceived susceptibility, barriers, nonhealth benefits, negative life events, self-efficacy, normative influence, and social prevalence were entered into the function simultaneously, the model was able to correctly classify 76.25% of the cases. Significant Pearson's correlations between negative health events and perceived susceptibility, and between perceived susceptibility, perceived normative influence, and lack of consistency with ideas and beliefs about the self suggested that what prompts smokers to consider quitting is a highly complex process.
