The relation between two indexes of readiness to quit smoking obtained at baseline and subsequent quitting 2-7 years later was examined. Baseline data from the Minnesota Heart Health Program were used to construct 3-item composites of interest in quitting (alpha = .76) and past quitting behavior (alpha = .64). With baseline smoking controlled, both measures predicted quitting at the 2- and 7-year follow-ups but not at 4 years. Only interest in quitting was significant at the 7-year follow-up when both indexes entered the model. Given the representative community sample and the long interval from baseline to the final assessment, the findings provide support for the readiness construct.
研究了在基线时获得的两个戒烟准备指标与2至7年后随后戒烟之间的关系。来自明尼苏达心脏健康项目的基线数据被用于构建对戒烟的兴趣（α = 0.76）和过去戒烟行为（α = 0.64）的3项综合指标。在控制了基线吸烟情况后，这两个指标在2年和7年随访时都能预测戒烟情况，但在4年随访时则不能。当两个指标都纳入模型时，只有对戒烟的兴趣在7年随访时具有显著意义。鉴于该社区样本具有代表性，且从基线到最终评估的时间间隔较长，这些研究结果为戒烟准备这一概念提供了支持。
