Social cognitive theories (e.g., ASE-model) propose that smoking cessation can be accomplished by changing underlying cognitive determinants such as attitudes, social influence, and self-efficacy. Others have argued that people's preferences for a health state can also predict behavior. In this study, preferences constitute the degree to which one is willing to give up a valuable good, that is survival, to obtain a desirable behavior (e.g., to quit smoking). The aim of this study is to investigate the impact of cognitive determinants and patients' preferences on the prediction of smoking cessation.
Data were collected as part of a randomized clinical trial. Smoking outpatients (N = 217) with cardiovascular disease were included. At baseline (T0), socio-demographic and clinical characteristics were measured. Social cognitions (pros of quitting, pros of smoking, social influence, and self-efficacy) and preferences (using a paper time trade-off measure (TTO)) were assessed at T1 (1 week). Smoking cessation was assessed at T2 (8 weeks).
Logistic regression analysis showed that socio-demographic (P = .92) and clinical (P = .26) factors did not predict smoking cessation, whereas social cognitions (P = .02) and preferences did (P = .00). On average, quitters are willing to give up an appreciable amount of survival years in order to quit smoking.
Preference for quitting was the strongest single predictor of smoking cessation.
社会认知理论（如 ASE 模型）提出，戒烟可通过改变潜在的认知决定因素来实现，如态度、社会影响和自我效能感。其他人则认为，人们对健康状态的偏好也能预测行为。在本研究中，偏好指的是一个人为了获得期望的行为（如戒烟）而愿意放弃一种有价值的东西，即生存的程度。本研究的目的是调查认知决定因素和患者偏好对戒烟预测的影响。
作为一项随机临床试验的一部分收集数据。纳入患有心血管疾病的吸烟门诊患者（N = 217）。在基线（T0）时，测量社会人口统计学和临床特征。在 T1（1 周）时评估社会认知（戒烟的好处、吸烟的好处、社会影响和自我效能感）和偏好（使用纸质时间权衡测量法（TTO））。在 T2（8 周）时评估戒烟情况。
逻辑回归分析表明，社会人口统计学因素（P = 0.92）和临床因素（P = 0.26）不能预测戒烟情况，而社会认知（P = 0.02）和偏好能够预测（P = 0.00）。平均而言，戒烟者为了戒烟愿意放弃相当数量的生存年限。
戒烟偏好是戒烟最强的单一预测因素。
