非喫煙者の受動喫煙対処行動による喫煙獲得“前熟考期”のステージ細分類

抄録

A system of classifying the pre-contemplation stage of smoking acquisition was developed, based on participants' responses to passive smoking. Japanese undergraduate students (N=390) participated in the study. They responded to questionnaires inquiring their stage of smoking acquisition, self-efficacy and temptation to smoke, decisional balance for smoking acquisition, and impressions about scenes depicting smoking. Responses of non-smokers clearly indicated four-stages of pre-contemplation about smoking that consisted of high, intermediate, and low antipathy to smoking, and the acceptance of passive smoking. The results also showed that measures of self-efficacy decreased, whereas temptation increased as smoking related activities advanced. Moreover, the acceptance of pros of smoking behavior increased as participants progressed toward smoking, whereas their concern for cons of smoking decreased. Furthermore, negative responses to pictures showing smoking scenes were strongest in non-smokers with a high antipathy to smoking, and participants' impressions of the scenes became increasingly positive as they progressed toward smoking. This study demonstrated the validity of the new classification of the pre-contemplation stage of smoking acquisition designed for developing preventive measures against smoking among young people.
