Authors' conclusions:
Interventions that aim to enhance partner support appear to have no impact on increasing long‐term abstinence from smoking. However, most interventions that assessed partner support showed no evidence that the interventions actually achieved their aim and increased support from partners for smoking cessation. Future research should therefore focus on developing behavioural interventions that actually increase partner support, and test this in small‐scale studies, before large trials assessing the impact on smoking cessation can be justified
