Research has shown that smoking-related cues are important triggers for craving. The objective of the present study was to test whether smoking cues in movies also function as triggers to evoke craving. To accomplish this, we conducted a pilot study in which we examined smokers' reactivity to smoking cues from a particular movie in a common cue-reactivity paradigm using pictures. In the main study, we tested whether smokers who are confronted with smoking characters in a movie segment have a greater desire to smoke than smokers confronted with non-smoking characters.
Using an experimental design, participants were assigned randomly to one of two movie conditions (smoking versus non-smoking characters).
In a laboratory, that reflected a naturalistic setting, participants watched a 41-minute movie segment.
A total of 65 young adults who smoked on a daily basis participated in the experiment.
Craving was assessed before and after watching the movie.
The pilot study revealed that pictures of smoking characters had strong effects on craving. However, when smokers actually watched a movie segment, no differences in craving were found between those who watched smoking characters and those who watched non-smoking characters. This finding was not affected by baseline craving, the time of the last cigarette smoked and daily smoking habits.
No effect of smoking cues in movies on craving was found, in contrast with research supporting the cue-craving link. Thus, if replicated, this might indicate that smoking cues in such contexts do not affect smokers' desire to smoke as expected.
研究表明,与吸烟相关的线索是引起渴望的重要触发因素。本研究的目的是检验电影中的吸烟线索是否也能作为引发渴望的触发因素。为此,我们进行了一项初步研究,在该研究中,我们使用图片在常见的线索反应性范式中检查了吸烟者对特定电影中的吸烟线索的反应性。在主要研究中,我们测试了在电影片段中面对吸烟角色的吸烟者是否比面对非吸烟角色的吸烟者更渴望吸烟。
使用实验设计,参与者被随机分配到两种电影条件(吸烟角色与非吸烟角色)之一。
在一个反映自然环境的实验室中,参与者观看了一个 41 分钟的电影片段。
共有 65 名每天吸烟的年轻人参加了实验。
在观看电影前后评估渴望程度。
初步研究表明,吸烟角色的图片对渴望有强烈的影响。然而,当吸烟者实际观看电影片段时,观看吸烟角色和观看非吸烟角色的人之间的渴望程度没有差异。这一发现不受基线渴望、最后一支烟的时间和每日吸烟习惯的影响。
与支持线索-渴望联系的研究相反,没有发现电影中的吸烟线索对渴望的影响。因此,如果得到复制,这可能表明在这种情况下,吸烟线索不会像预期的那样影响吸烟者的吸烟欲望。
