| Abstract: | Smoking is regarded as the world’s leading reason for preventable and premature mortality and morbidity. As stopping to smoke can reduce smoking-related health consequences considerably, smoking interventions are highly relevant. Previous academic literature has hinted that intrinsic motivation and self-efficacy are two crucial drivers in successful smoking cessation. Therefore, for the present study, data of a smoking intervention was analysed to assess how and under which conditions self-efficacy and intrinsic motivation predict successful smoking termination and how they are related to the quitting strategy to stop at once, or to having a depression. The smoking intervention was conducted by trained counsellors at the Outpatient Smoking Cessation Clinic at the Medisch Spectrum Twente, Enschede, the Netherlands. This clinical study has a longitudinal design of four waves where data of 344 participants was collected with questionnaires or, in the case of people’s smoking status, with biochemically validated exhaled carbon monoxide (CO) levels and cotinine measures at baseline (T0), three, six, nine and 15 months (T1-T4). Against empirical evidence and theory, the results showed that self-efficacy and intrinsic motivation did not significantly influence smoking cessation, quitting at once or depression in an expected way. Though, the study supported that stopping at once is significantly and positively related to smoking cessation. Limitations of the present study as well as implications for research and practice are discussed for the clinical health literature. |
