摘要
目的 探讨中老年男性吸烟者在香烟选择决策过程中的行为偏好模式。方法 52例吸烟者和48例非吸烟者完成E-Prime2.0软件编制的以香烟及钱币为线索的决策任务。任务分为两个,其中任务一为电脑屏幕上随机呈现一张香烟或钱币图片,受试者按键确定是否选取该图片,其中无论按选取键还是放弃键,受试者均可在规定时间内连续按键,以显示其对物品图片的偏好以及获取或规避的总数量;任务二为电脑屏幕上同时左右随机呈现第一个任务中看到的香烟和钱币图片,要求受试者在这两张图片中选择一张,在进行任务的同时记录受试者的选择模式、选择次数、选择结果等。结果 与对照组比较,任务一中吸烟组香烟选择次数、钱币选择次数、香烟选择总次数、钱币选择总次数均显著增多,差异有显著意义(t=2.834~6.517,P<0.05)。任务二中吸烟组和对照组对钱币的选择次数均显著大于对香烟的选择次数(t=15.484~35.883,P<0.01);但两组对钱币和香烟选择次数比较差异无显著性(P>0.05)。任务一和任务二中吸烟组对香烟的选择次数与尼古丁依赖程度、吸烟持续时间和每日吸烟量均无显著相关性(r=0.013~0.238,P>0.05)。结论 中老年男性吸烟者对香烟选择存在决策偏好效用。
Objective To investigate the behavioral preference patterns of middle-aged and elderly male smokers during decision-making for cigarette selection. Methods A total of 52 smokers (smoking group) and 48 non-smokers (control group) participated in the decision-making task based on cigarette and money developed by E-Prime 2.0 software. The task was divided into two parts. In part 1, a picture of cigarette or money was randomly displayed on a computer screen, and the subject used a button to determine whether to select the picture;the subject could press the selection key or the abandonment key continuously within the specified time to show his preference for the item in the picture and the total number of times of acquisition or avoidance. In part 2, both pictures of the cigarette and money in part 1 were displayed on the computer screen, and the subject was required to select one picture;selection mode, number of selections, and selection results were recorded. Results In part 1 of the task, compared with the control group, the smoking group had significant increases in the numbers of times of cigarette selection and money selection and the total numbers of pressings of cigarette button and money button (t =2.834-6.517, P <0.05). In part 2 of the task, the number of times of money selection was significantly higher than that of cigarette selection in both groups (t =15.484-35.883, P <0.01), but there were no significant differences in the numbers of times of money selection and cigarette selection between the two groups (P >0.05). In the smoking group, the number of times of cigarette selection in the two parts of the task was not signi- ficantly correlated with the degree of nicotine dependence, duration of smoking, and daily smoking amount (r =0.013-0.238, P >0.05). Conclusion Middle-aged and elderly male smokers have preference in decision-making for cigarette selection.
