“…The TTM has been used to design interventions to promote positive behaviours such as physical activity/exercise (Adams and White, 2003;Spencer et al, 2006), healthy eating (Armitage et al, 2004;Horwath, 1999;Spencer et al, 2007), and mammography screening (Ashworth, 1997;Spencer, Pagell, and Adams, 2005), as well as to help people avoid pregnancy and sexuallytransmitted diseases (Horowitz, 2003) and overcome harmful behaviours such as smoking and substance abuse (Migneault, Adams, and Read, 2005;Spencer et al, 2002). The apparent success of some of these communication and intervention programmes suggests that it might be worth applying insights from the model to the promotion of lower-carbon and other sustainability-related behaviours.…”
