If we look at examples in the second category, interventions on motivation, we see, for example, strategies that support behavioural change in a more conscious way and are, for example, based on the self-determination theory (Ryan et al., 2006) and rewarding ( van Dooren et al., 2019). Support in self-regulation (category 3) can, for example, happen through providing feedback (Casal et al., 2017) on behaviour and goal setting (Strecher et al., 1995). Examples of strategies in the fourth category, resilience support, are pats on the back and emotional support from the environment. A number of strategies in this category have been implemented in the Stopadvisor intervention (see Brown et al., 2014). In the last category, habit formation, focusing on how one's own identity is seen is a strategy (see e.g. Hoie et al., 2010).
