Many cigarette smokers make multiple attempts to quit before they are successful. Implicit theories of smoking (ITS)-beliefs about whether smoking behavior is something that is changeable (incremental belief) or fixed (entity belief)-may play a role in quitting. Four iterations of the cross-sectional, nationally-representative Health Information National Trends Survey (HINTS) were used in logistic regression analyses to examine how smokers' ITS relates to (1) attempts to quit in the past 12 months; (2) considering quitting in the next 6 months; and (3) the interaction between ITS and past quit attempts on considering quitting. Greater incremental beliefs were not significantly associated with having tried to quit in the past year (β = .27, p = .055); however, greater incremental beliefs were associated with greater likelihood of considering quitting in the next 6 months (β = .22, p = .04). Past quit attempts did not moderate the association between ITS and considering quitting (β = .59, p = .10). Results suggest that incremental beliefs are associated with increased intentions to quit.
许多烟民在成功戒烟前会多次尝试。关于吸烟行为是否可改变（增量信念）或固定（实体信念）的吸烟内隐理论（ITS）可能在戒烟中起作用。使用四组横断的、全国代表性的健康信息国家趋势调查（HINTS）数据，通过逻辑回归分析检验了吸烟者的 ITS 与（1）过去 12 个月内的戒烟尝试；（2）未来 6 个月内的戒烟考虑；以及（3）ITS 与过去戒烟尝试之间的相互作用如何与考虑戒烟相关。更强的增量信念与过去一年的戒烟尝试之间没有显著关联（β = .27，p = .055）；然而，更强的增量信念与未来 6 个月内戒烟的可能性更大相关（β = .22，p = .04）。过去的戒烟尝试并没有调节 ITS 与考虑戒烟之间的关联（β = .59，p = .10）。结果表明，增量信念与戒烟的意愿增加有关。
