An extended version of the theory of planned behavour: Prediction of intentions to quit smoking using past behaviour as moderator
It was hypothesised that: (i) intentions to quit smoking were predictable from group identity, self-identity, moral norms and past quit attempts, beyond the components of the Theory of Planned Behaviour (TPB), and (ii) that past experiences with the behaviour (quit attempts) would increase the predictive utility of the extended TPB model on intentions. The data was collected among 357 daily smoking students (M = 24 years). The TPB components accounted for 12.3% of the variance in quitting intentions, while the extension variables added 16.5% to the explained variance in intentions beyond the impact of the TPB. Past behaviour had the strongest impact on intentions (α = 0.30), followed by mor…
Using an extended version of the theory of planned behaviour to predict smoking cessation in two age groups
The aim of this study was twofold: (i) to test the utility of the theory of planned behaviour (TPB) in predicting intentions to quit smoking and subsequent behaviour in two age groups, and among women and men, and (ii) to examine whether descriptive norms, moral norms and past behaviour predict intentions and behaviour beyond the impact of the TPB components. Analyses were based on data from a prospective sample of 447 daily smokers (adolescents 16–19 years, n = 174, M = 17.5, adults 35–55 years, n = 311, M = 44 years). The TPB accounted for 31.8% and 38% of the variance in intentions in the adolescent and adult groups, respectively. The extension variables added 12.6% and 12.1% to the …
Premeditated automaticity : the role of explicit cognition in the development of obsessive smoking
- Abstract The purpose of the present study was to examine the role of explicit cognitions in relation to the development of obsessive smoking passion. Data derives from a longitudinal internet survey conducted among 939 daily smokers over a period of four months. Mental representations were the strongest predictor of obsessive smoking passion (ß=.47, p<.001) followed by habit strength (ß=.25, p<.001) and number of cigarettes smoked (ß=.09, p<.01). Altogether the variables accounted for 48% of the variance in obsessive smoking passion. The results indicated that mental representations, along with automatic processes, play an important role in the prediction of obsessive smoking passion. The…
