Despite previous evidence supporting the use of the Cigarette Purchase Task (CPT) as a valid tool for assessing smoking reinforcement, research assessing how environmental changes affect CPT performance is scarce.
This study addressed for the first time the differential effect of treatment condition [Cognitive Behavioral Treatment (CBT) + Behavioral Activation (BA) versus CBT + BA + Contingency Management (CM)] on cigarette demand among treatment seeking smokers with depressive symptoms. It also sought to assess whether reductions in smoking consumption arranged over the course of an intervention for smoking cessation impact on in-treatment cigarette demand.
Participants were 92 smokers with depressive symptoms from a randomized clinical trial that received eight weeks of either CBT + BA or CBT + BA + CM. Individuals completed the CPT 8 times; the first during the intake visit and the remaining 7 scheduled once a week in midweek sessions. Cotinine samples were collected in each session.
Participants receiving CBT + BA + CM showed higher reduction in cigarette demand across sessions than participants receiving CBT + BA, although this comparison was only significant for the intensity index (p = .004). Cotinine was positively related to cigarette demand (all p values < .001), although this association became less prominent across sessions. In-treatment cotinine decreases were associated with demand reductions (all p values < .001), but this association was not significant for elasticity.
Reductions in nicotine intake arranged over the course of an intervention for smoking cessation impact in-treatment cigarette demand.
尽管先前有证据支持使用香烟购买任务（CPT）作为评估吸烟强化的有效工具，但评估环境变化如何影响 CPT 表现的研究却很少。
本研究首次探讨了治疗条件[认知行为治疗（CBT）+行为激活（BA）与 CBT+BA+Contingency Management（CM）]对有抑郁症状的吸烟寻求者的香烟需求的差异影响。它还试图评估在戒烟的干预过程中减少吸烟量是否会对治疗中的香烟需求产生影响。
参与者为来自一项随机临床试验的 92 名有抑郁症状的吸烟者，他们接受了八周的 CBT+BA 或 CBT+BA+CM。个体完成了 8 次 CPT；第一次在摄入就诊时进行，其余 7 次在治疗中期每周一次的就诊中进行。在每次就诊中都收集了可替宁样本。
接受 CBT+BA+CM 的参与者在整个治疗过程中显示出更高的香烟需求降低，而接受 CBT+BA 的参与者则显示出更高的香烟需求降低，尽管这种比较仅在强度指数上具有统计学意义（p=0.004）。可替宁与香烟需求呈正相关（所有 p 值均<0.001），尽管这种关联在整个治疗过程中变得不那么明显。治疗过程中的可替宁降低与需求降低相关（所有 p 值均<0.001），但在弹性方面没有统计学意义。
在戒烟干预过程中减少尼古丁摄入会影响治疗中的香烟需求。
