Smoking cessation interventions that use implementation intentions have shown promising results. Implementation intentions are if-then plans that specify certain behaviour within a situational context. This study examines whether dyadic planning (i.e., involving a non-smoking partner) is more effective than individual planning in quitting smoking.
This longitudinal single-blind randomized controlled trial involves a baseline questionnaire, end-of-day measurements for three weeks, and a follow-up questionnaire after three months. Single-smoking couples were randomized to a dyadic or individual planning condition. After the intervention, which 176 couples received, smokers attempted to quit smoking, and the diary measurements started.
smoking abstinence, number of cigarettes smoked and relationship satisfaction.
At follow-up, both planning groups showed similar quit rates (33%, dyadic; 30%, individual) and a similar significant decline in number of cigarettes smoked (almost 50%). For most smokers, the smoking pattern shown in the diary seemed to be indicative of smoking behaviour at follow-up. Relationship satisfaction declined minimally, in both intervention groups and in both smokers and partners.
The involvement of a non-smoking partner in the planning did not increase its effectiveness. However, couple participation and daily measurements during a quit attempt could be important components of future interventions.
使用实施意向的戒烟干预措施已显示出良好的效果。实施意向是一种情境性的特定行为计划，即“如果……那么……”计划。本研究旨在检验在戒烟方面，双元规划（即涉及不吸烟者的伴侣）是否比个体规划更有效。
这是一项纵向单盲随机对照试验，包括基线问卷、为期三周的每日测量和三个月后的随访问卷。单吸烟夫妇被随机分配到双元或个体规划组。干预后，176 对夫妇接受了干预，吸烟者尝试戒烟，日记测量开始。
戒烟成功率、吸烟量和关系满意度。
随访时，两个规划组的戒烟率相似（双元组 33%，个体组 30%），吸烟量也明显下降（近 50%）。对于大多数吸烟者来说，日记中的吸烟模式似乎表明了随访时的吸烟行为。在干预组和吸烟者及伴侣中，关系满意度都略有下降。
非吸烟者伴侣参与规划并不会增加其效果。然而，在戒烟尝试中，夫妻双方的参与和每日测量可能是未来干预措施的重要组成部分。
