The Partners for Change Outcome Management System (PCOMS; Miller & Duncan, 2004) is also widely researched and used, both in the USA (e.g., Reese, Norsworthy, & Rowlands, 2009a, 2009b, Norway (e.g., Anker, Duncan, & Sparks, 2009), the Netherlands (e.g., Janse, de Jong, van Dijk, Hutschemaekers, & Verbraak, 2017), Ireland (Murphy, Rashleigh, & Timulak, 2012), Australia (Hansen, Howe, Sutton, & Ronan, 2015), China (She et al, 2018), and Denmark (Davidsen et al, 2017). In February 2018, a total of 92 partners or certificated PCOMS trainers from 14 different countries were registered at the homepage of the S. D. Miller initiated project the "International Center for Clinical Excellence" (2018) or at the homepage of the B. L. Duncan launched "Heart and Soul of Change Project" (2018).…”
