The purpose of this thesis was to gain insight into why female college students initiate smoking. This study examined the major factors influencing the formation of such habit among this group. The tool used to study these factors was the questionnaire. Questionnaires were administered to randomly selected female students on the Oregon State University (OSU) campus. The Memorial Union and campus library were the only locations where these questionnaires were administered. Results of the study suggested that peers and curiosity were paramount in influencing smokers to initiate smoking. The results also indicated that, with the exceptions of curiosity and the belief that smoking was "adult", there were no differences between early and late initiators in the extent to which the factors under examination influenced them to start smoking. Both curiosity and the belief that smoking was "adult" had greater influence on early initiators to smoke their first cigarettes than they did with late initiators. Lastly, college-related stress was found to increase the daily level of smoking among smokers. For non-smokers, health concern and odor were factors that influenced them greatly to remain smoke-free. Overall, the findings suggested that prevention efforts should focus on strategies that reduce the acceptability of smoking in the social environment. / Graduation date: 1999
