Partner Influence, Self-Control, and Smoking Cessation: A Study Using EMA

描述(由申请人提供)：在美国，烟草使用是主要的可预防的死亡原因。尽管大多数吸烟者想戒烟，但大多数戒烟尝试都不成功。研究表明，伴侣的支持对戒烟至关重要，但操纵提供支持的研究并不能提高戒烟率。有可能的是，研究人员只考察了一个伴侣在一个时间点的感知支持行为，并没有捕捉到影响复发和禁欲的实际近端伴侣行为。当前应用程序的目标是了解实时伴侣行为是如何影响吸烟的。中心假设是，一方的行为可以通过影响吸烟者的自我控制，间接影响另一方的吸烟/戒烟行为。该项目的基本原理是，确定影响吸烟的伴侣行为将提供所需的知识，以加强戒烟的行为干预。核心假设将通过追求两个具体目标来检验：1)找出与吸烟密切相关的积极和消极的伴侣行为；2)找出对吸烟结果有适度影响的个体差异。在第一个目标下，将使用生态瞬时评估(EMA)来检查伴侣行为对吸烟者的瞬时自我控制和随后的吸烟结果的影响。预计积极的伴侣行为(与吸烟无关)将与吸烟者更强的自控力和更好的后续吸烟结果相关。相反，消极的伴侣行为(与吸烟无关)将与较低的自我控制力和较差的后续吸烟结果相关。在第二个目标下，在基线上测量的个体差异将作为这些影响的调节因素进行测试。预计关系质量高的吸烟者，积极的伴侣行为与改善的吸烟结果之间的联系将比低关系质量的吸烟者强。还预计，高冲动的吸烟者的负面伴侣行为与较差的吸烟结果之间的关联将比低冲动的吸烟者更强。最后，S预计，对于戒烟动机较低或尼古丁依赖程度较高的参与者，自控力与吸烟结果之间的关联将更强。这项拟议的研究在理论上是创新的，因为它在论证合作伙伴方面与先前的研究有所不同 与戒烟尝试无关的行为是戒烟最重要的。这项拟议的研究在方法上是创新的，因为它涉及到在吸烟者戒烟尝试期间通过EMA近距离研究吸烟者和伴侣的行为，而不是通过一个人在基线或后续行动时的自我报告评估。这项拟议的研究意义重大，因为它是确定哪些伴侣的行为实际上对演员戒烟有影响的第一步。归根结底，这些知识有可能为加强的行为和社会干预提供信息，其中包括将伴侣行为的改变作为戒烟的一个组成部分。

DESCRIPTION (provided by applicant): Tobacco use is the leading preventable cause of mortality in the United States. Although the majority of smokers want to quit, most quit attempts are unsuccessful. Research suggests that partner support is critical to smoking cessation, but studies manipulating the provision of support do not improve quit rates. It is possible that studie examining perceived support behaviors at only one time point from only one partner do not capture the actual proximal partner behaviors that influence relapse and abstinence. The objective of the current application is to understand how real-time partner behaviors affect smoking. The central hypothesis is that the behavior of one partner can affect the smoking/quitting behaviors of the other partner indirectly, through their influence on the smoker's self-control. The rationale for this project is that identifying the partner behaviors tha influence smoking will provide the knowledge needed to strengthen behavioral interventions for smoking cessation. The central hypothesis will be tested by pursuing two specific aims: 1) identify positive and negative partner behaviors proximally associated with smoking, and 2) identify individual differences that moderate proximal influences on smoking outcomes. Under the first aim, ecological momentary assessment (EMA) will be used to examine the effect of partner behaviors on the smoker's momentary self-control and subsequent smoking outcomes. It is expected that positive partner behaviors (unrelated to smoking) will be associated with greater self-control strength in the smoker and better subsequent smoking outcomes. Conversely, negative partner behaviors (unrelated to smoking) will be associated with lower self-control strength and poorer subsequent smoking outcomes. Under the second aim, individual differences measured at baseline will be tested as moderators of these effects. It is expected that the association between positive partner behavior and improved smoking outcomes will be stronger for smokers with high than with low relationship quality. It is also expected that the association between negative partner behaviors and poorer smoking outcomes will be stronger for smokers with high impulsivity than with low impulsivity. Finally, it s expected that the association between self-control strength and smoking outcomes will be stronger for participants low in motivation to quit or high in nicotine dependence. The proposed research is theoretically innovative because it departs from prior research in arguing that partner behaviors unrelated to the quit attempt are the most important for smoking cessation. The proposed research is methodologically innovative because it involves studying both smoker and partner behaviors proximally through EMA during a smoker's quit attempt, rather than through one person's self-reported assessments at baseline or at follow-up. The proposed research is significant because it is a first step in determining which partner behaviors are in fact consequential for the actor's smoking cessation. Ultimately, such knowledge has the potential to inform enhanced behavioral and social interventions that include changes in partner behavior as a component of smoking cessation.
