目标。本研究考察了TPB预测戒烟意向和戒烟行为的能力。此外，研究人员还研究了未来取向、吸烟数量、计划、过去行为以及意图与其他预测因素之间的相互作用等因素的预测能力。材料和方法。这些数据来自对奥斯陆大学103名每天吸烟的学生（平均年龄24.6岁，平均吸烟年数= 8年）的纵向调查。这些数据是在T1（2003年10月）和T2（2004年2月）通过自我填写的问卷收集的，记录实际戒烟结果。TPB成分占戒烟意向方差的30%，情感态度和描述性规范是戒烟意向的最强预测因子。有序回归分析显示，意图是随后戒烟行为的一个临界显著预测因素，而PBC的影响不显著（模型1）。附加变量的纳入改善了模型的拟合，香烟数量和计划似乎是行为的重要预测因子（模型2）。正如预测的那样，感知控制与戒烟意图之间存在显著的相互作用（模型3）。Nagelkerke R-2从。07型号1到。模型2中的54，最后到。模型3中58。结果表明，情感态度和描述性规范在激励吸烟者戒烟方面的作用比其他TPB预测因子更重要。结果还表明，自我调节策略在成瘾行为中很重要。
Objectives. The present study examined the ability of the TPB to predict the intention to quit smoking and quitting behaviour. In addition, the predictive power of future orientation, number of cigarettes smoked, planning, past behaviour and the interactions between intention and other predictors was examined.Material and methods. The data were derived from a longitudinal survey among 103 daily smoking students at the University of Oslo (mean age 24.6 years, mean number of years of smoking = 8 years). These data were collected by means of self-administered questionnaires at T1 (October 2003) and at T2 (February 2004) in terms of recording actual quitting.Results. The TPB components accounted for 30% of the variance in quitting intentions, and affective attitude and descriptive norm emerged as the strongest predictors of quitting intention. Ordinal regression analysis showed that intention was a borderline significant predictor of subsequent quitting behaviour, while the impact of PBC was non-significant (model 1). The inclusion of the additional variables improved the fit of the model, with number of cigarettes and planning appearing as significant predictors of behaviour (model 2). As predicted, there was a significant interaction between perceived control and intentions on quitting (model 3). Nagelkerke R-2 increased from .07 in model 1 to .54 in model 2, and finally to .58 in model 3.Conclusions. The results indicate that affective attitude and descriptive norm play a more crucial role than the other TPB predictors in motivating smokers to quit. The results also indicate that self-regulatory strategies are important in relation to addictive behaviours.
