Research suggests that a blunted response to nondrug rewards, especially under conditions associated with strong cigarette cravings, is associated with reduced abstinence motivation in daily smokers. One limitation of previous studies is that they have largely focused on monetary rewards as broad representative of nondrug rewards. It remains unclear whether craving dampens responses to more abstract nondrug rewards, such as personal values. Personal values often have a positive valence and are frequently assumed to remain stable across time and situations. However, there may be time-varying and contextual influences on smokers' appraisal of values in daily life. Characterizing fluctuations in value importance in relation to relapse precipitants (eg, craving) may inform interventions that leverage personal values as motivation for cessation.
Daily smokers (n = 18) completed ecological momentary assessment surveys measuring the importance of specific personal values and smoking-related variables during 8 days of monetarily reinforced cigarette abstinence. We hypothesized that value ratings would demonstrate adequate within-person heterogeneity for multilevel modeling and that within-person fluctuations in craving would be negatively related to valuing personal health.
All values demonstrated adequate within-person variability for multilevel modeling. Within-person craving was negatively related to health valuation (p = .012) and a cross-level interaction (p > .0001) suggested this effect is stronger for individuals who report greater overall craving.
Greater craving is associated with decreased importance of personal health in the moment, particularly for those with high average levels of craving. Timely interventions that bolster importance of health during moments of elevated craving can potentially improve cessation outcomes.
This study builds on research highlighting the positive influence of personal values in motivating behavior change. Values are an often used, but poorly studied, construct that has considerable utility in smoking cessation. Valuing personal health is frequently reported as a primary motivator for a quit attempt. Inasmuch as personal health is a distal nondrug reward used to motivate smoking abstinence, naturalistic evaluation of health importance, and motivators for continued smoking (ie, craving) could inform the timing and content of smoking treatment. This study is among the first to evaluate momentary assessment of personal values and craving within daily life.
研究表明,对非药物奖励的反应迟钝,尤其是在与强烈的烟瘾相关的情况下,与日常吸烟者的戒断动机降低有关。以往研究的一个局限性在于,它们主要关注货币奖励,将其作为非药物奖励的广泛代表。目前尚不清楚烟瘾是否会削弱对更抽象的非药物奖励(如个人价值观)的反应。个人价值观通常具有积极的效价,并且经常被认为在时间和情境中保持稳定。然而,在日常生活中,吸烟者对价值观的评估可能会受到随时间变化和情境的影响。描述与复发诱因(如渴望)相关的价值重要性波动,可能为利用个人价值观作为戒烟动机的干预措施提供信息。
每日吸烟者(n = 18)在8天的货币强化戒烟期间完成了生态瞬时评估调查,测量特定个人价值观和吸烟相关变量的重要性。我们假设价值评级将显示出足够的个体内异质性以进行多层次建模,并且个体内渴望的波动将与重视个人健康呈负相关。
所有价值观都显示出足够的个体内变异性以进行多层次建模。个体内渴望与健康评估呈负相关(p = 0.012),并且跨层次交互作用(p > 0.0001)表明,对于总体渴望程度更高的个体,这种影响更强。
更大的渴望与当下个人健康重要性的降低相关,特别是对于那些平均渴望水平较高的人。在渴望加剧时及时加强健康重要性的干预措施可能会改善戒烟结果。
本研究建立在强调个人价值观在促进行为改变方面的积极影响的研究基础上。价值观是一种经常被使用但研究较少的概念,在戒烟方面具有相当大的效用。重视个人健康经常被报告为戒烟尝试的主要动机。由于个人健康是用于激励戒烟的一种远期非药物奖励,对健康重要性以及持续吸烟的动机(即渴望)进行自然主义评估,可以为吸烟治疗的时机和内容提供信息。本研究是首批在日常生活中评估个人价值观和渴望的瞬时评估的研究之一。
