Mapping behaviour change concepts to a future nature walks intervention for people discharged from a mental health hospital

Outcome expectancies	A lay summary of evidence (see Table 1) about the benefits of nature walks will be given to people recently discharged from a mental health hospital to help them develop accurate knowledge about the health consequences of participating in the intervention
Positive attitude	Information provided to participants will aim to promote positive feelings towards the outcomes of nature walks
Personal and moral norms	Participants will be given a diary to self-monitor their participation in the group-based nature walks.
Personal relevance	Participants will be encouraged to articulate what they hope to achieve from participating in the intervention. The literature for instance, suggests that these may include reducing stress, improving mood and losing body weight.
Individual, targeted information	Participants will be given information about a local walking group in the community where they will live once they are discharged from a mental health hospital. Maps of their local area will be given should they wish to walk on their own or with a family member or friend. Participants will be supported to identify local walk routes.
Relapse prevention	Participants will identify personal barriers (e.g. low mood, stress, stigma – see Table 2) to participating in a local community walking group and be shown how to develop action and coping plans for times when these barriers feel insurmountable.
Intention formation and concrete plan	Participants will set personal and incremental goals to participate in nature walks and be supported to achieve these goals.
Self-efficacy	Participants will be encouraged to describe their experiences of nature walks with a view to encouraging self-belief in their abilities to participate in group-based walks and walking on their own
Subjective norms	Participant’s family members, friends, GP and/or mental health team will be informed about the participant’s involvement in the intervention and asked to encourage participation
