“…CHBs may negatively contribute to the intention formation process, independently from behaviour-specific factors (self-efficacy, risk perceptions, outcome expectancies) (Berli, Loretini, Radtke, Hornung, & Scholz, 2014;Fleig et al, 2015;Radtke, Scholz, Keller, & Hornung, 2012), and through the self-efficacy mediating role (Matley & Davies, 2017). CHBs may also interact with self-efficacy (they negatively predict intention when self-efficacy is low, Storm et al, 2016) and risk perception (they positively predict intention when risk perception is high, Radtke, Kaklamanou, Scholz, Hornung, & Armitage, 2014). However, CHBs' effects have not been examined on IWCD in an MHBC context, but only in healthy populations with low/medium intentions for behaviours change (Radtke et al, 2012;Berli et al, 2014;Fleig et al, 2015;Storm et al, 2016).…”
