Eight hundred volunteers who attended smoking clinics at Roswell Park Memorial Institute from 1964-1965 were followed up five years later to ascertain their current smoking status. From three waves of a mailed questionnaire, plus a telephone campaign, we obtained 559 usable responses. The relationship between smoking status at the five-year follow-up and clinic protocols and selected social and psychological characteristics as determined during the clinics were examined.Of those individuals contacted five years after the clinic, 17.8 per cent were not smoking. Variations inIn the early 1960s the Surgeon General of the United States became actively involved in evaluating the evidence relating lung cancer to cigarette smoking. From these evaluations, definitive reports evaluating the literature linking lung cancer to smoking were published' and measures were sought to deal with this problem. One method which we applied was the smoking withdrawal clinic. We now have had the opportunity to examine the smoking status, and factors related to it, of 559 patients five years after they attended a series of clinics at Roswell Park Memorial Institute.We were concerned with a number of questions: What proportion of those attending clinics are successful over the long term? Do variations in clinic procedure result in different levels of success? What are the characteristics of those who, five years after attendance, had succeeded or failed in their attempt to withdraw from smoking?In studying such long-term behavior change, we were guided by the sociological literature dealing with this phenomenon. The most commonly studied behavior changes have been incremental ones: those where new behaviors have replaced old ones. Hypotheses dealing with incremental behavior, however, may also be applicable to the study of decremental behavior, the elimination of behavioral patterns with no replacement, such as smoking cessation.The relevant literature suggests that behavior change is more likely when the innovation is compatible with previously held ideas, values, and behavioral patterns; when the function of the new behavior is understood; when the new behavior is seen by the adopter as personally advantageous over old behavior; when the decision to adopt is reversible; when old behavior is feasible to give up, for example, where physiologic dependence is not involved; and when influential individuals in the subject's milieu accept or support the innovation.2Specifically regarding smoking behavior, we hypothesized that smoking cessation would be negatively associated with the amount of habituation involved and positively associated with possession of a personal psyche which can withstand withdrawal trauma, a knowledge of the ill effects of smoking, a perceived personal threat of lung cancer, and behavior and support from others in the personal milieu which is compatible with withdrawal. Almost all of our hypotheses were confirmed.
