ACKNOWLEDGEMENTS First and foremost I would like to thank the nurses and students for participating in this research and for giving up their time to talk to me with frankness. Special thanks are due to my loving husband Malcolm and to Clare, Graham, Alison and Sam for their constant love, faith, patience and support during the course of the study. I 'am also grateful to my friends and colleagues for their help and encouragement. I would like to thank my supervisor Professor Jill Macleod Clark, without whose wisdom, understanding, and encouragement, this study would not have been possible. This study was made possible in part by the National Board for Nurses, Midwives and Health Visitors for Northern Ireland and their support is gratefully acknowledged. 2 ABSTRACT The aim of this study was to evaluate the impact of an individualised cessation intervention on the smoking behaviour of qualified nurses and student nurses and to explore the experiences of nurses who attempted to give up smoking. A comparison or reference group comprised qualified nurses and student nurses who wished to give up smoking but did not receive the intervention. In phase one, data were collected pre and post intervention and analysed using a combination of quantitative and qualitative methods. Self reports of smoking cessation were objectively verified by measuring carbon monoxide in expired alveolar air and cotinine in saliva. Twenty five per cent of nurses in the intervention group stopped smoking at one year compared with 8% in the reference group. This suggests that an individualised smoking cessation intervention is an appropriate method for helping nurses stop smoking and that Prochaska and DiClemente's (1982) transtheoretical model of behavioural change is a useful framework upon which to base smoking cessation interventions. In phase two semi-structured interviews were undertaken with qualified nurses and student nurses to explore the reasons why some stopped smoking and others continued. A qualitative approach to analysis revealed that nurses who successfully stopped experienced something akin to a 'Damascus Road' experience and had internalised the effects of smoking on their health and professional role. Specific barriers to stopping smoking were also identified particularly amongst the qualified nurses who described the powerful relationship they enjoyed with cigarettes. This relationship was linked to varying levels of stress incurred in their everyday lives. Student nurses described the impact of important peer relationships which were in turn nurtured by the smoking condoning culture within the College of Nursing. In examining the effect of smoking on the nurse's role the findings suggest that nurses who smoke are compromising their role as promoters of health in this area and that the students studied have little understanding of the meaning of health promotion. The implications of these findings for professional practice are discussed. 3 TABLE OF CONTENTS PageNo. TITLE 1 ACKNOWLEDGEMENTS 2 ABSTRACT 3 TABLE OF CONTENTS 4 LIST OF TABLES AND FIGURES 12 LIST OF
