“…There are a number of candidate active ingredients (e.g., “change talk”) and candidate mechanisms of change, (e.g., “arguing oneself into change”) (Bem, 1967 ; Miller, 1983 ; Gollwitzer, 1999 ; Miller and Rollnick, 2002 , 2004 , 2013 ; McNally et al, 2005 ; Moos, 2007 ; Arkowitz et al, 2008 ; Gaume et al, 2008 ; Apodaca and Longabaugh, 2009 ; Miller and Rose, 2009 ; Barnett et al, 2010 ; Glynn and Moyers, 2010 ; Lee et al, 2010 ; Berger and Villaume, 2013 ; Moyers and Miller, 2013 ; Apodaca et al, 2014 ; Berger and Bertram, 2015 ; Copeland et al, 2015 ; Magill et al, 2015 , 2018 ). In a previous study (Dobber et al, 2020 ), we performed a systematic literature search for active ingredients and mechanisms of change in PsychInfo, in PubMed, and in textbooks on MI. Based on the research (Gollwitzer, 1999 ; McNally et al, 2005 ; Gaume et al, 2008 ; Apodaca and Longabaugh, 2009 ; Barnett et al, 2010 ; Glynn and Moyers, 2010 ; Lee et al, 2010 ; Apodaca et al, 2014 ; Copeland et al, 2015 ; Magill et al, 2018 ) and MI theory (Bem, 1967 ; Miller, 1983 ; Gollwitzer, 1999 ; Miller and Rollnick, 2002 , 2004 , 2013 ; McNally et al, 2005 ; Moos, 2007 ; Arkowitz et al, 2008 ; Gaume et al, 2008 ; Apodaca and Longabaugh, 2009 ; Miller and Rose, 2009 ; Barnett et al, 2010 ; Glynn and Moyers, 2010 ; Lee et al, 2010 ; Berger and Villaume, 2013 ; Moyers and Miller, 2013 ; Apodaca et al, 2014 ; Berger and Bertram, 2015 ; Copeland et al, 2015 ; Magill et al, 2015 , 2018 ...…”
