- Brief summaryWe aim to help smokers to quit, by finding a successful way to involve their non-smoking partner. Partner support as part of a cessation intervention seemed unrelated to greater rates of successful. Hence, intervening on support after a quit attempt might not be the right solution to the problem. Support from a non-smoking partner, both prior to and during a self-set quit attempt, was related to less smoking. After the quit date, this effect was even more pronounced. Perhaps, the support should be received also before the quit date.

In our RCT, we aim to involve the partner before the quit date by asking the couple to jointly create a plan for the smoker to quit smoking. This would change the role of the partner from just a support-provider to a part of the team: quitting smoking becomes a dyadic effort. We will examine the effect of dyadic planning to quit smoking in comparison to individual planning. Dyadic planning is when an individual is creating a plan, together with their partner (instead of on their own), on when and where quitting might be difficult, and creating plans of what to do when they have cravings or when they are in a situation where they usually smoke.

Both partners will fill in a daily diary, to provide insight into the efficacy of the intervention. For example, it could show differences between the intervention and control group in how a couple deals with a weak moment, when craving for a cigarette is high. With a diary, the sequence of events can be determined and consequently, whether associations extend over a certain time period.
