“…Finally, all included studies applied observational coding methods (e.g., Houck, Moyers, Miller, Glynn, & Hallgren, 2010; Martin, Moyers, Houck, Christopher, & Miller, 2005; Miller, 2000; Miller, Moyers, Ernst, & Amrhein, 2003; Miller, Moyers, Ernst, & Amrhein, 2008;
Miller, Moyers, Manuel, Christopher, & Amrhein, 2008) to the study of MI within-session process. While studies using the Motivational Interviewing Treatment Integrity Scale (Moyers, Martin, Manuel, Miller, & Ernst, 2003; Moyers, Martin, Manuel, Miller, & Ernst, 2007; Moyers, Martin, Manuel, Miller, & Ernst, 2010) were eligible, these studies must have used these data to examine one or more paths outlined in the MI process model as proposed by Miller and Rose (2009; see also Arkowitz et al, 2008). …”
