越来越多的证据表明，吸烟与抑郁症之间存在正相关关系。此外，抑郁症状，无论是既往的、当前的还是亚综合征，似乎都会对戒烟努力产生负面影响。虽然抑郁症通常通过临床访谈或自我报告进行评估，但很少有人在戒烟研究的背景下评估与抑郁症有关的已知神经认知缺陷(例如，全球减速)。因此，这项研究检验了简单的反应时间--情感中性词的颜色命名--是否可以预测以前抑郁的吸烟者(N=28)12个月的戒烟结果。结果表明，反应时间与抑郁症状之间存在显著的正相关关系，反应时间较慢的人复发的风险更高。通过自我报告评估的基线抑郁症状与戒烟结果无关，也不能预测戒烟结果。Logistic回归分析的结果进一步表明，反应时间对戒烟结果的预测增加了增量差异。因此，简单的反应时间可能会捕捉到通常在自我报告问卷中没有评估的抑郁的方面。讨论了这些结果对戒烟研究的理论和临床意义。
Burgeoning evidence points to a positive association between cigarette smoking and depression. Moreover, depressive symptomatology, whether historical, current, or subsyndromal, appears to negatively influence smoking cessation efforts. Whereas depression is typically assessed via clinical interview or self-report, rarely are the known neurocognitive deficits linked to depression (e.g., global slowing) assessed in the context of smoking cessation research. Hence, this study examined whether simple reaction time-color naming of affectively neutral words-is predictive of 12-month smoking cessation outcome among a sample of formerly depressed smokers (N = 28). Results revealed a significant, positive correlation between reaction time and depressive symptoms such that those who exhibited slower reaction times were at heightened risk to relapse. Baseline depressive symptoms, as assessed via self-report, neither correlated with nor predicted smoking cessation outcome. Results from logistic regression analyses further showed that reaction time added incremental variance to the prediction of smoking cessation outcome. Therefore, simple reaction time may capture aspects of depression not typically assessed in self-report questionnaires. These results are discussed in terms of their theoretical and clinical implications for smoking cessation research.
