泰勒和他的同事们表明，戒烟和改善心理健康之间存在明显的联系。这可能有助于让患者放心，戒烟不一定会对心理健康产生持久的不利影响，甚至可能改善心理健康。尽管如此，新闻稿和媒体报道的读者相信这项研究提供了戒烟对改善心理健康的因果关系的证据，这是可以原谅的，但事实并非如此。作者对他们的发现提出了三种可能的解释：戒烟改善心理健康;改善心理健康导致戒烟;或者一个共同的因素解释了两者。我们在他们的调查结果中看不到多少支持媒体报道中对第一种解释的明显认可。
Taylor and colleagues show a clear association between smoking cessation and improved mental health. 1 This may help reassure patients that quitting smoking need not have a lasting adverse effect on mental health, and that it might even improve mental health. Nevertheless, readers of the press release and media coverage could be forgiven for believing that the study provided evidence of a causal effect of smoking cessation on improved mental health, which it did not.The authors present three possible explanations for their findings: smoking cessation improves mental health; improved mental health causes cessation; or a common factor explains both. We see little in their findings to support the apparent endorsement of the first over the second and third of these explanations in the media coverage.
