“…High quality communication, conversely, is associated with lower rates of smoking, more negative attitudes and higher self-efficacy to refuse cigarette use (de Leeuw et al, 2008;Harakeh et al, 2005Harakeh et al, , 2010Otten et al, 2008;Ringlever, Otten, de Leeuw, & Engels, 2011;; lower rates of alcohol use and higher self-efficacy to refuse (van den Eijnden et al, 2011;Koning et al, 2013;Mares, Lichtwarck-Aschoff, & Engels, 2013;Spijkerman et al, 2008). While Koning et al (2014) found no association between quality of communication and alcohol use, they still promote the use high quality conversations. Three studies found that frequent communication was indirectly protective against alcohol, tobacco and cannabis use, only when combined with high quality communication and high PCC (Cleveland et al, 2005;Huansuriya, Siegel, & Crano, 2014;Huver, Engels, Vermulst, & de Vries, 2007).…”
