“…In two recent meta-analyses, de Roten, Zimmermann, Ortega, and Despland (2013) identified 12–16 hr as an adequate dose of MI workshop training and noted that coaching and feedback further enhance skill, while Schwalbe, Oh, and Zweben (2014) showed that MI training effects were best maintained through a minimum of 5 hr of coaching from an expert MI trainer over a 6-month period. Reviews of the MI training literature reveal that although workshop training alone used to be common (Madson, Loignon, & Lane, 2009; Söderlund, Madson, Rubak, & Nilsen, 2011), the vast majority of recent MI training studies include at least some postworkshop coaching (Madson, Villarosa-Hurlocker, Schumacher, Williams, & Gauthier, 2019). Although a survey of MI trainers suggests that this intensive training may reflect years of practices and attitudes that community providers must unlearn in order to learn MI (Schumacher, Madson, & Nilsen, 2014), our experience training psychology interns in MI suggests substantial variability in dose of training necessary to achieve competence in MI even within that group (Schumacher et al, 2018).…”
