Self- and other-efficacy are related to current smoking during a quit attempt: a daily diary study in single-smoking couples.

To start the quit attempt with high self-efficacy, and maintain it throughout the quit attempt seems important for successful abstinence, as this might help to overcome a lapse. This is the first study to show that other-efficacy is related to smoking behaviour. However, more research is needed regarding the temporal order of smoking and efficacy, from both smokers and spouses.
