Internet programs for smoking cessation are widely available but few controlled studies demonstrate long-term efficacy.
To determine the 13-month effectiveness of an Internet program presenting a set sequence of interactive steps, and the role of depressed affect.
In a randomized controlled trial sponsored by the American Cancer Society, a treatment condition (n = 1,106) was compared to a control site (n = 1,047).
More treatment condition participants were abstinent (30-day point prevalence) than control site participants (12.9% vs. 10.1%, p < .05) at 13 months. This effect was greater among participants not reporting depressed affect (15.0% vs. 10.1%, p < .01). Among smokers who reported depressed affect, there was no difference in abstinence between the treatment and control conditions.
Data support the long-term efficacy of an Internet intervention for cessation modeled on a structured, in-person treatment approach, especially for participants not experiencing daily depressed affect.
戒烟的互联网项目已经广泛应用，但很少有对照研究能证明其长期效果。
确定一套按顺序呈现的互动步骤的互联网项目在 13 个月时的有效性，以及抑郁情绪的作用。
在美国癌症协会的一项随机对照试验中，治疗组（n = 1,106）与对照组（n = 1,047）进行比较。
13 个月时，治疗组的戒烟者（30 天点流行率）多于对照组（12.9%比 10.1%，p <.05）。对于不报告抑郁情绪的参与者，这种效果更大（15.0%比 10.1%，p <.01）。在报告抑郁情绪的吸烟者中，治疗组和对照组之间的戒烟率没有差异。
数据支持基于结构化、面对面治疗方法的互联网干预对戒烟的长期有效性，尤其是对不经历日常抑郁情绪的参与者。
