“…Customised remote systems that monitor and assist users are usually called Personalised Guidance Systems (PGS) or Personalised Support Systems (PSS). Often, such systems are internet-, mobile-, or game-based (Honka, Kaipainen, Hietawitzla, & Saranummi, 2011;Kato, 2010;Krebs, Prochaska, & Rossi, 2010;Krishna, Boren, & Balas, 2009;Kumar et al, 2013;Minutolo, Esposito, & De Pietro, 2012;Pawar, Jones, Van Beijnum, & Hermens, 2012;Riley et al, 2011). PGS have been proposed for disease management (Fjeldsoe, Marshall, & Miller, 2009;Gibbons et al, 2011), psychotherapeutic use (Andrews, Cuijpers, Craske, McEvoy, & Titov, 2013;Barak, Hen, Boniel-Nissim, & Shapira, 2008;Mitchell, Vella-Brodrick, & Klein, 2010), and health behaviour change (Cugelman, Thelwall, & Dawes, 2011;Webb, Joseph, Yardley, & Michie, 2010).…”
