“…A growing body of research demonstrates empirical support for the role of all three MCO pillars in advancing psychotherapy processes (e.g., working alliances) and outcomes (e.g., change in symptom functioning) in samples totaling over 7,000 clients (e.g., Davis et al, 2018; Hook et al, 2013; Kivlighan et al, 2019; Owen et al, 2014, 2016; Pérez-Rojas et al, 2019). Given the data supporting MCO in psychotherapy, scholars recently began to theorize and empirically study MCO in supervision (Cook et al, 2020; Drinane et al, 2021; Hook et al, 2016; King et al, 2020; Watkins, Hook, Mosher, & Callahan, 2019; Watkins, Hook, Owen, DeBlaere, Davis, & Callahan, 2019, Watkins, Hook, Owen, DeBlaere, Davis, & Van Tongeren, 2019; Wilcox et al, 2022).…”
