“…TTM has been used extensively in alcohol reduction research, but mainly on a quantitative level (Campbell, 1997;Chang, McNamara, Wilkins-Haug, & Orav, 2007;Heather, McCambridge, Research, & Team, 2013;Hernandez-Avila, Burleson, & Kranzler, 1998;Hunter-Reel, McCrady, Hildebrandt, & Epstein, 2010;Reed et al, 2005;Velasquez, von Sternberg, Dodrill, Kan, & Parsons, 2005). In addition, several exploratory studies with wide ranges of participant demographics have used TTM as a framework for understanding and examining contraceptive use on a quantitative level (Choi & Shin, 2015;Emmett & Ferguson, 1999;Ha, Jayasuriya, & Owen, 2003, 2005. A number of studies looking to increase contraception use and initiation used TTM as a basis to develop an intervention, and then evaluate its effectiveness (Chung-Park, 2008;Davidson et al, 2015;Lee, Tsai, Tsou, & Chen, 2011;Peipert et al, 2008;Wang, Wang, Cheng, Hsu, & Lin, 2007).…”
