Literature provides qualitative evidence on smoking behaviour among healthcare professionals. Smoking behaviour of nurses and medical doctors have been examined to understand their attitudes and perceptions regarding their smoking behaviour. Being a healthcare professional and a smoker at the same time may represent some conflict due to the dilemma it creates with a professional position. Therefore it is important to understand how healthcare professionals make sense of their health behaviours. Health psychology professionals aim to promote health related behaviours by conducting various interventions. The aim of the current study is to understand how a health psychology student make sense of their smoking behaviour by focusing on dilemmatic aspects of this position. By using qualitative in-depth interviews, this study aims to understand the perspective of a health psychology student who is a smoker. Interpretative phenomenological analysis was used to conduct analysis on a single case. In total, four super-ordinate themes were developed, one of the themes was reported in detailed. The theme, justification in terms of escaping from reality, highlights perceptions relevant to dilemmatic aspects, therefore it was chosen to discuss dilemmatic position of the case. The findings were mainly discussed in the context of cognitive dissonance theory. Analysis showed that the case used rationalisation and denial to justify smoking behaviour. Overall, this study provides interesting narrative that shows how a person on a dilemmatic position make sense of their own behaviour.
